effectiveness of eu biofuels sustainability criteria in the context of land acquisitions in africa abstract in recent years land is becoming an important commodity and the land sector in many developing countries has been object of growing foreign acquisitions the aim of the paper is to analyze whether the requirements set by the eu renewable energy directive introducing biofuels sustainability criteria has induced the european investors acquiring land for producing biofuel feedstocks to adopt more sustainable strategies first we review the factors that may induce a corporation to adopt sustainable behavior and corporate social responsibility csr strategies in the context of land acquisitions second the paper illustrates our original evidence on european land acquisitions in africa and on the behavior of the investors involved then we use a logistic model to estimate the variables affecting the investor s choice to certify its actions and to adopt csr strategies our evidence shows that the main factors influencing the probability that an investor chooses to certify the sustainability of its actions are the sector in which it operates the fact of acquiring land in more than one foreign country and the characteristics of origin and destination country interestingly the european economic operators involved in acquisitions for biofuel crops show significantly lower probability of being certified therefore the eu sustainability criteria seem to be ineffective in guaranteeing and verifying the sustainability of the european land investments in africa joint efforts by european union member states target countries and private sector operators are necessary to prevent the negative effects of land acquisitions on local stakeholders and the environment

management of social issues in supply chains a literature review exploring social issues actions and performance outcomes the social dimension of sustainable development and its impact on supply chains have so far received less attention than the environmental dimension the aim of the research is to explore the intersection between social issues corporate social responsibility csr actions and performance outcomes a structured literature review of social issues in supply chains is presented analysing the research published so far in peer reviewed publications linking csr and supply chain management allows the exploration of strategies and performance outcomes with a focus on social issues the corresponding responsible supply chain actions adopted by firms to address these issues are grouped into communication compliance and supplier development strategies social and economic as well as buyer and supplier performance are identified as the key outcomes but the interactions among these constructs would require further research this paper contributes to the understanding of managing social issues in supply chains by linking social issues responsible supply chain actions and performance outcomes the paper consolidates related research by offering an overarching conceptual framework and points to future research directions and simultaneously provides insights into the management of social issues in supply chains

light duty vehicles and external impacts product and policy performance assessment abstract in order to demonstrate that welfare theory can be put into practice mathematical programming methods are used here which can handle the aggregation problems facing us when information concerning the relative valuation of external factors emissions safety risks non renewable energy use noise etc is highly uncertain product and policy performance measures are presented and then applied to one time period real data on the single perhaps most welfare affecting man made consumer product of the 20th century light duty vehicles ldvs the focus when examining costs imposed on society due to individuals or other economic units purchase and use of ldvs is here the total external cost from the choice of ldv technology the relative weights of the external factors are then determined endogenously by first using for each ldv model the unconstrained set of weights most favorable to itself the flexibility of the relative weights is then constrained according to assumed knowledge about true external relative costs by this procedure it is possible to aggregate the multiple societal impact factors of ldvs and thus to measure the total external impact of individual ldv models relative to current best practice technology

project evaluation by potential tax reform abstract shadow prices are derived for small open economies with several production sectors experiencing constant returns to scale small projects affect the balance of trade domestic prices of non traded goods and factors and sector scales only domestic prices affect welfare and only if there is not domestic price equalization generally a project s net benefits depend upon the potential tax and tariff reform made possible or necessary through the balance of trade effect border prices are right for traded goods but domestic good shadow pricing requires knowing the direction of at least one reversible available tax reform and presuming optimality with respect to available reforms

foreign exchange equivalence and project appraisal procedures this paper investigates the implications of different adjustment mechanisms for shadow pricing traded and nontraded goods in a flexible price model a foreign exchange equivalent rule that can be readily adapted whatever the adjustment mechanism is derived it is shown that traded commodities are always valued at border prices and nontraded commodities can always be shadow priced in terms of changes in production and consumption of traded goods valued at border prices the role of the shadow exchange rate and the implications for measuring the balance of payments effect when no tax adjustment policy is assumed are also discussed copyright 1990 by royal economic society

shadow pricing with suboptimal policy rules abstract this paper aims to clarify different views on the validity of the little mirrlees border price rule for project evaluation in a context where the government chooses its controls suboptimally in a systematic fashion the rule is shown to be valid quite generally for small public sector projects when the government s response restores market clearing in nontradeables and foreign exchange it can be invalid in contexts of a non market clearing or b private sector projects that generate profits distributed to households in the latter case special treatment of profit effects is required along the lines described by little and mirrlees 1974

unbundling the biofuel promise querying the ability of liquid biofuels to deliver on socio economic policy expectations abstract while excitement around biofuels initially focused on finding a clean and secure alternative to fossil fuels many other expectations have subsequently been attached to the biofuel boom biofuels are not only expected to mitigate climate change or foster domestic energy security but also to generate employment provide opportunities to smallholders and support decentralized energy systems this paper interrogates the expectations attached to biofuels we begin by examining how policies in consumer and producer countries articulate a series of expectations for biofuels that are bundled with the promise of cleaner energy using the rationales behind these expectations to derive criteria for success we then review evidence from the published literature on biofuel outcomes against these criteria to assess whether the most prevalent assumptions have been met we find that policy expectations for biofuels are often expressed in narrow terms failing to capture important potential impacts for example focusing on new jobs in the formal sector rather than job quality or whether employment offsets livelihood costs associated with biofuel investments some expectations have proven elusive irrespective of the metrics employed for example using biofuels to improve energy access in remote rural areas the paper concludes by discussing implications for policy and practice

shadow prices and substitution in trade distorted economies abstract this paper derives simple and operational shadow pricing rules in a three sector three factor general equilibrium model incorporating nontraded goods under the little mirrlees method if a single simple and empirically plausible condition is satisfied the accounting ratio for land will exceed unity and those for capital and labor will lie below unity if this condition is not satisfied or cannot be verified it is still possible to fix some accounting ratios above or below unity just from knowledge of the signs of substitution patterns in consumption and factor intensity patterns in production guidelines are also derived for setting the shadow prices of nontraded goods or quota restricted imports it is shown that the alternative domestic price method generally yields less useful guidelines than the little mirrlees method

promoting sustainable palm oil viewed from a global networks and flows perspective abstract global demand for palm oil is increasing to fulfil worldwide needs for cooking oil food ingredients biofuels soap and other chemicals in response palm oil production is rapidly expanding which promotes economic growth in producing countries but also leads to serious environmental and social problems such as destruction of tropical forests climate change and threats to small holder livelihoods for these reasons palm oil production and use have become highly controversial however the global character of palm oil production and consumption the number of different actors involved and its multiple uses makes promotion its sustainability highly complex individual nation states can no longer control and regulate a global flow like palm oil and alternative governing networks appear involving private companies and ngos acknowledging the roles of such governance networks with different forms of power means that relying only on economic and political power to explain current dynamics in the palm oil sector is inadequate in global networks like palm oil supply encompassing transnational material flows and multiple actors the relevance of each actor relates to his position in the network power in global palm oil supply is therefore not only related to their position in the vertical supply chains but also to their role in the horizontal networks new forms of power in networks arise from steering the networks programming and from connecting different networks switching in the multiple networks that compose global palm oil provision today different programmers and switchers play critical roles this is briefly illustrated in this paper on the basis of different cases of active steering in global palm oil provision

community currencies and sustainable development a systematic review community or complementary currency systems have spread all around the world most often they have been promoted as tools to foster sustainable development albeit they differ in terms of specific objectives while many case studies have tried to assess the actual impact of these systems there has been no global analysis summarizing their global impact this paper aims to fill the gap by exploring whether complementary currencies contribute to the three pillars of sustainable development we use the systematic review methodology on an original dataset gathering most academic publications on the topic in english french and spanish our main findings suggest that community currencies mostly contribute to social sustainability and that their economic benefits are somewhat limited due to their small scale and the lack of awareness on their scope moreover very few studies explicitly identify environmental outcomes finally this review reveals some limits regarding current methods for impact assessment in this field therefore it encourages more standardization to provide greater accuracy and strengthen the legitimacy of community currencies in order to foster their continued development

limits to economic growth as shown by a computable general equilibrium model abstract economic growth is distinguished from commercial growth and is defined in this article as the growth of the value a society puts in monetary terms on all commercial and non commercial goods and values it possesses during a certain period a computable general equilibrium model is used to show the impact of changes in the endowments preferences and production possibilities on economic income which in the model comprises all wealth besides land with its natural resources and labor energy is the key endowment to drive an economy the model leads in an intuitive way to the following conclusions 1 societies should start to use appropriate indicators for true economic growth rather than just for commercial growth as measured by gross national product 2 all types of economic growth are limited no matter if based on endowment growth production efficiency growth or changes in preferences 3 economic growth should be oriented more towards increasing production efficiency and less towards using more natural resources 4 human population growth puts at risk the possibilities for average economic growth per person 5 we should get better prepared to use solar energy in the future 6 besides economic growth there exists pure utility growth which is not measurable in monetary terms it includes much of scientific progress in the long run and is of great importance even though it cannot be included in an indicator of economic growth

relative shadow prices and the shadow exchange rate abstract the divergent conclusions that have been reached in the literature as to the role of the shadow exchange rate in project appraisal are reconciled in this paper it is shown that the shadow exchange rate is not needed to assess the relative shadow prices of either traded or nontraded goods

constructing sustainable palm oil how actors define sustainability abstract biofuels as a renewable source of energy have gained considerable importance in recent years the use of biofuels is expected to rise since national governments of developed nations like the us and european countries see it as one of the ways to fulfill climate targets and increase the security in their energy supply production of biofuels is also expected to rise as developing nations see in biofuels the opportunity for connecting to international markets through supplying a new demand in the energy market several studies report on the environmental social and economic gains and detriments that can arise from increased biofuel production and consumption however research that provides insight into the way in which such issues are defined by actors within the product chain is scarce in this article we analyse how the strategies and value definitions of actors involved in the production and consumption of biofuels lead to specific definitions of sustainability the empirical material concerns the chain of palm oil production in colombia and electricity generation in the netherlands it is analysed using the method of action in context which allows us to uncover the level and source of diversity of sustainability definitions in the product chain while the current growth in production of palm oil is definitely buyer driven the analysis of various activities in the chain shows that several aspects of sustainability are defined in more complex actor fields throughout the product chain

the environmental kuznets curve ekc theory part a concept causes and the co2 emissions case abstract the main purpose of this study is to capture the main features of the environmental kuznets curve ekc concept according to the ekc theory the process of economic growth is expected eventually to limit the environmental degradation created in the early stages of development the ekc concept leads many researchers from the early 1990s to assume that each economy should focus on its growth and any environmental problems will be eventually eliminated by the process of economic growth several studies attempt to test empirically the ekc hypothesis using data on many countries and examining various types of environmental degradation while other studies examine the underlying factors that may drive such a relationship this article reviews the evolution of the ekc concept and the possible causes of an ekc pattern like the distribution of income the international trade pollution haven hypothesis structural changes technical progress and improvements in energy efficiency institutions and governance and consumer preferences as co2 emissions are a pollutant with global effects several studies deal with the possible ekc pattern for co2 emissions and these studies are discussed separately the various critiques on the ekc concept are reviewed in the second article of this work

project appraisal procedures and the evaluation of foreign exchange different procedures for evaluating foreign exchange have been suggested in the project appraisal manuals of unido and little and mirrlees while it is widely agreed that the manuals differ in their practical procedures there has been disagreement as to whether they are equivalent in principle using a model due to boadway we show that the manuals differ in principle the little mirrlees procedure can be given an interpretation which correctly values traded and non traded goods in project appraisal while the unido formula for the shadow exchange rate is not required when the balance of payments constraint is binding

how biofuel policies backfire misguided goals inefficient mechanisms and political ecological blind spots abstract the development of an economically viable biofuel industry rests on strong state subsidies for production and processing creation of markets through government procurement fuel blending mandates price controls as well as foreign trade tariffs and quotas and multiple interventions in agricultural ecological and other regulations we use an approach grounded in agrarian political economy to critically analyze the literature on how biofuel policies interact with broader production trade and agro ecological processes we focus on policies involving the most prominent crops in the places where biofuel production has advanced the most i e usa brazil and the eu but also extend analysis to their relations with broader transformations in production commercial and even governance practices around the world we investigate the political and economic interests driving biofuel policies and how these set the terms in which state interventions and policies are conceived and implemented we find that these are not developed and implemented according to environmental or inclusive pro poor development purposes but according to state interests in energy security and its intersection with a tense alliance between corporate sectors rendering many policy mechanisms ineffective or even outright counterproductive to effectively facilitate more socially and environmentally sustainable energy production and agricultural practices

the seesaw of germany s biofuel policy tracing the evolvement to its current state today biofuels represent one of the most common options for larger scale substitution of conventional fuels due to the trans sectoral nature of biofuels a multitude of factors and actors determine the according policies of governments and the beliefs of societies especially since some impacts of biomass cultivation for bioenergy production are not yet fully understood this article aims at showing the drivers that led to an introduction of biofuel policies in germany and explains germany s pioneering role in the promotion of bioenergy thereby the focus lies on the role of the main actors and their composition of so called discourse coalitions the analysis indicates that the origin of the biofuel industry was a result of national and supranational market interventions as well as it was intermittently an instrument of supporting renewable energies along the seesaw of germany s biofuel policies seven discourse coalitions were identified who compete for discursive hegemony in order to gain political influence

the challenge of measuring biofuel sustainability a stakeholder driven approach applied to the french case measuring biofuel sustainability requires dealing with a wide variety of complex and conflicting values at stake consequently the biofuel capacity to contribute to one specific value cannot lead to any absolute conclusion about the overall sustainability of biofuel the scope of the sustainability concept may vary depending on individuals preferences the time scale and the geographical region based on the 5 pillars sustainability concept that includes social economic environmental legal and cultural considerations the present study proposes to assess several biofuel sustainability options for france by 2030 through a stakeholder driven approach rather than seeking to reach a consensus our approach allows us to capture the wide diversity of stakeholders perspectives and preferences french stakeholders perceive 22 different sustainability criteria for biofuels with a very low level of agreement between the different segments of professions feedstock producers biofuel producers refining industry fuel distributors car manufacturers end users government and ngos in order to operationalize the sustainability assessment a set of indicators has been identified with stakeholders that allows us to measure the capacity of biofuels to fulfill each of their criteria seventeen biofuel options were assessed with regards to economic social environmental cultural and legal considerations allowing the identification of the strengths and weaknesses of each biofuel

sine qua nons of sustainable biofuels distilling implications of under performance for national biofuel programs biofuels have been promoted worldwide under the assumption that they can support several strategic policy goals while mitigating associated risks drawing on published evidence on performance contributing papers to this special section question assumptions commonly attributed to biofuels their carbon neutrality their positive effect on rural livelihoods and policymakers ability to effectively govern for sustainability this paper takes these findings as its starting point and asks what next for countries wishing to advance biofuels as one option for the necessary divestment from fossil fuels deriving recommendations for national biofuel programs from past performance is no easy task context complexity power dynamics and scaling pose significant challenges to achieving policy aims we are nevertheless able to distill a set of sine qua nons indispensables for sustainable biofuel governance from the evidence and change management literatures they are put forward not as recipes for success but minimum conditions and best bet approaches requiring testing deliberation and refinement perhaps the most fundamental sine qua non is to pursue options that downscale global demand as current levels of global energy consumption if only in the transport sector cannot be met by biomass derived agrofuels in a way that meets social and environmental sustainability goals

toward consilience between biology and economics the contribution of ecological economics abstract during its ten year history ecological economics has made a real difference in the way economists look at the natural world and in the way biologists look at the economy in this survey article we examine the contributions to the journal in terms of e o wilson s concept of consilience that is his argument that the methods and assumptions of any field of study should be consistent with the known and accepted facts in other disciplines in particular we examine the contributions of ecological economics to reconciling the economic theory of the consumer and producer with biophysical reality

the adjustment of expectations to a change in regime a study of the founding of the federal reserve the founding of the federal reserve system in 1914 led to a substantial change in the behavior of nominal interest rates the authors examine the timing of this change and the speed with which it was effected they then use data on the term structure of interest rates to determine how expectations responded their results indicate that the change in policy regime was rapid and that individuals quickly understood the new environment they were facing copyright 1987 by american economic association

project appraisal and foreign exchange constraints a comment a paper in this journal by blitzer dasgupta and stiglitz i98i hereinafter bds entitled project appraisal and foreign exchange constraints examines the implications of various non optimal macroeconomic adjustment policies for project evaluation the discussion is presented in terms of a simple two good one consumer economy with price distortions which lead the ratio of the domestic price of the exported good e to the domestic price of the imported good i to be greater than the internati onal price ratio it is argued that the resulting trade gap will force the government to pursue an adjustment policy which may take the form of taxation of income or commodities rationing or foreign borrowing and it is shown that the choice of policy will determine the appropriate shadow price formulae to be used in project appraisal the view that world prices provide shadow prices for traded goods is argued to be correct for some but not all of the macroeconomic policies considered this comment argues that the bds analysis fails to specify how tax revenue is to be incorporated in the model as a result the various policy options open to the government are not clearly brought out we set out below in section i an amplified version of the bds general equilibrium model which includes tax revenue and use it to show how the different adjustment mechanisms have to be related to the public sector budget constraint in section ii we reconsider their analysis and show that if either an income or a commodity tax on the importable is used to ensure public sector balance then world prices remain shadow prices for traded goods in section iii we make the point that the presence of import tariffs does not imply in the context of a real general equilibrium model that the balance of payments constraint will be violated the conclusion is drawn that endogenous foreign borrowing cannot be analysed without respecifying the basic bds model our comment is confined to the problem of shadow pricing traded goods in the bds model we do not consider rationing as a means of macroeconomic adjustment policy nor do we comment on their section iii where they analyse the additional problems which follow from introducing a non traded commodity into the model

scaling up biofuels a critical look at expectations performance and governance this editorial is the introduction to a special issue of scaling up biofuels a critical look at expectations performance and governance which assesses biofuels contribution to sustainability governance and upscaling the issue aims to contribute to a more informed evidence based policy debate on the role of bioenergy for sustainable development it comprises six review papers that share a solutions oriented and policy focused approach towards the assessment of sustainability bioenergy production and consumption is not evaluated as an isolated industry or additionality instead it is assessed as an inherent component of the broader social ecological system and history of which it forms a part synthesizing available empirical evidence on performance and contextualizing the evidence in view of expectations and bioenergy governance in and over time the papers address the role of biofuels for climate mitigation their ability to deliver on socio economic policy expectations the actual performance in view of risk anticipation and mitigation the role of state policy considering sector development and sustainability and the ability of certification schemes to deliver on market conversion and quality the synthesis paper draws on the empirical findings to develop a set of sustainability conditions sine qua nons that have to be considered in processes of policy making and upscaling

social sustainability assessments in the biobased economy towards a systemic approach abstract the majority of impact assessments for the biobased economy are primarily focused on the environmental and techno economic aspects while social aspects are rarely considered this study proposes a modified systemic approach for a social sustainability impact assessment of the biobased economy based on a review on the common methodologies for assessing social impacts accordingly the proposed approach follows the four general iterative steps of social life cycle analysis slca as it considers all life cycle phases of the biobased economy the systemic approach considers the potential social impacts on local communities workers and consumers as the main three groups of the stakeholders the review showed that the most common social indicators for inventory analysis within the biobased economy include health and safety food security income employment land and worker related concerns energy security profitability and gender issues multi criteria decision analysis mcda was also highlighted as the broadly utilized methodology for aggregating the results of impact assessments within the biobased economy taking a life cycle perspective this study provides a holistic view of the full sustainability of research design and innovation in the biobased economy by suggesting the integration of the social aspects with techno economic and an environmental life cycle assessment our proposed systemic approach makes possible to integrate the social impacts that are highly valued by the affected stakeholders into the existing sustainability models that focus only on environmental and techno economic aspects we discuss the steps of the proposed systemic approach in order to identify the challenges of applying them within the biobased economy these challenges refer mainly to the definition of the functional unit and system boundaries the selection and the analysis of social indicators inventory analysis the aggregation of the inventory to impact categories and the uncertainties associated with the social sustainability evaluation the result of this review and the proposed systemic approach serve as a foundation for industry and policy makers to gain a better insight into the importance of social sustainability impacts assessment within the biobased economy

reply to commentary on the special issue scaling up biofuels a critical look at expectations performance and governance abstract the special issue scaling up bioenergy identifies major policy expectations attached to biofuels production worldwide and it provides systematic reviews of actual biofuel performance and governance in these areas papers address the extent to which policy expectations related to climate change mitigation energy security rural livelihoods and risk mitigation have been achieved and the effectiveness of public and private governance in advancing sector sustainability building on these findings the synthesis paper asks what next for countries wishing to advance national biofuel programmes as one option for the necessary divestment from fossil fuels among other sine qua nons the special issue highlights the urgent need to downscale global energy demand and to stop treating biofuels as an isolated sector goldemberg et al 2018 query several aspects of our approach from research design data collection to our recommendation to apply the precautionary principle in research as well as policy making unfortunately goldemberg et al 2018 incorrectly portray our main argument moreover they claim bias in our approach and mistakes in our empirical evidence however without bringing forward an evenhanded critique of research philosophy methodology or referencing different empirical literature we fully stand behind our research philosophy and findings presented

growing green money mapping community currencies for sustainable development abstract parallel sustainable monetary systems are being developed by civil society groups and non governmental organisations ngos informed by ecological economics perspectives on development value economic scale and growth and responding to the unsustainability of current global financial systems these parallel systems of exchange or community currencies are designed to promote sustainable development by localising economic development building social capital and substituting for material consumption valuing work which is marginalised in conventional labour markets and challenging the growth based monetary system however this international movement towards community based ecological economic practices is under researched this paper presents new empirical evidence from the first international study of the scope and character of community currencies it identifies the diversity scale geography and development trajectory of these initiatives discusses the implications of these findings for efforts to achieve sustainable development and identifies future research needs to help harness the sustainability potential of these initiatives

project appraisal and foreign exchange constraints a rejoinder in their comment on blitzer dasgupta and stiglitz i98i bds dinwiddy and teal i987 dt state that many of the points made in this note apply to bell and devarajan i983 however for clarity we confine ourselves to commenting on only bds the purpose of this note is to point out that none of dt s criticisms of the bds piece applies to our i 983 paper in fact we make essentially the same points using a somewhat more general model than dt our results are consistent with but not subsumed by those of dt and are therefore sometimes at variance with those of bds dt s main claim is that bds s assertion that the border price rule fails to hold when commodity taxation is used as the equilibrating device is false this stricture does not apply to our i 983 paper for in every single case we consider the relative shadow prices of the two tradeable goods are shown to be their relative border prices see our equations 22 and 23 28 and 29 and 33 and 34 dt show that when commodity taxation is the equilibrating device shadow prices are proportional to world prices in contrast to bds s claim we derive the same result in the case when the tariff on one of the tradeable goods is the equilibrating device p 474 moreover dt s specific criticisms of bds s treatment of the public sector s budget do not carry over to our model unlike bds we do specify how tax revenues are incorporated in the system see our equation i4 nor did we overlook the accounting relationship between the public sector budget deficit and the current account deficit 1 we state t he government s budget deficit or surplus registers an equal change in the government s net foreign assets through foreign borrowing or lending p 46i hence endogenous foreign borrowing in our model arises precisely in the case when the public sector s budget constraint is not satisfied due to tax rates and public expenditures being exogenously given to conclude while dt make several valid criticisms about the bds paper their attempt to tar our i983 paper with the same brush is unwarranted

shadow prices for project evaluation under alternative macroeconomic specifications for purposes of social cost benefit analysis a project may be viewed as a disturbance to the economy displacing it from some initial equilibrium to a new one but the new configuration will depend on which particular variables adjust to restore equilibrium this paper examines the shadow prices for project evaluation under alternative assumptions about how equilibrium is restored when the government reacts by altering its foreign exchange reserves the shadow prices coincide with those advocated in the manuals on social cost benefit analysis however if the government adjusts its domestic expenditures or tariff rates the shadow prices will differ from those of the manuals except insofar as the relative shadow prices of tradeables remain their relative border prices the paper first presents the model followed by two cases in which domestic prices and wage rates do not vary because ad valorem tariffs are fixed and one case in which they are endogenous

multi actor governance of sustainable biofuels in developing countries the case of mozambique this paper describes and analyses the multi actor governance process that made mozambique the first african nation state to develop a national policy framework for sustainable biofuels the paper draws on findings from action research conducted in mozambique between december 2008 and july 2012 we analyse interactions between the changing governance context the course of the multi actor governance process and the choices in relation to governance framework characteristics and content for four successive stages of governance framework development this provides the basis for reflection on the competences required for effective multi actor sustainability governance and a discussion about the role of the nation state in sustainability governance of global economies such as biofuels the governance framework for sustainable biofuels has contributed to a more transparent and secure investment climate for biofuels in mozambique key factors for success were 1 the presence of different types of competences during the various stages of the governance framework development 2 closing the gap between licences to sell and licences to produce across different governance levels and 3 balancing between the short and long term objectives for biofuel production in mozambique and requirements of global biofuel markets developing country nation states can provide an essential contribution to these success factors for global governance of sustainable biofuels

limits to growth and sustainable development grappling with ecological realities abstract the paper has three main sections the first discusses the limits to growth debate of the 1970s identifying concern with three potential kinds of limits ecological limits to the physical scale of economic activity limits to the economic welfare to be derived from growth of economic activity and social limits to economic growth the second section explores the same issues through the sustainable development literature of the late 1980s and the 1990s to date the principal change over the 20 years concerned a period also framed by the stockholm environment conference and unced is far greater acceptance of the existence of threatening environmental damage and the need for active policy to address it no consensus has yet emerged however on the relationship between economic growth and welfare or ecological or social sustainability the third section indicates the scale of the task if global economic growth is to be reconciled with ecological sustainability and advocates a strategy for sustainability that principally involves differentiating between north and south and forging new economic relations between them

project appraisal procedures and the evaluation of foreign exchange a comment in 1986 dinwiddy and teal analyzed the shadow exchange rate ser in a tariff distorted small economy containing two traded and one non traded good contrary to their claim i maintain a ser is inherent to their model even if the balance of payments constraint is binding it equals the value of the marginal consumption basket at market prices divided by its value at world or foreign exchange equivalent fee prices shadow prices defined in welfare terms equal the products of the ser and 1 the world or fee prices of goods or 2 marginal products of factors at world prices copyright 1990 by the london school of economics and political science

evaluating projects and assessing sustainable development in imperfect economies we are interested in three related questions 1 how should accounting prices be estimated 2 how should we evaluate policy change in an imperfect economy 3 how can we check whether intergenerational well being will be sustained along a projected economic programme we do not presume that the economy is convex nor do we assume that the government optimizes on behalf of its citizens we show that the same set of accounting prices should be used both for policy evaluation and for assessing whether or not intergenerational welfare along a given economic path will be sustained we also show that a comprehensive measure of wealth computed in terms of the accounting prices can be used as an index for problems 2 and 3 above the remainder of the paper is concerned with rules for estimating the accounting prices of several specific environmental natural resources transacted in a few well known economic institutions

the founding of the fed and the behavior of interest rates what can be learned from small samples abstract we take issue with angelini s 1994 claim that the founding of the federal reserve was not responsible for a change in the stochastic process followed by short term interest rates we argue that angelini s failure to reject the null hypothesis of no regime change around the date of the founding of the fed is due to the low power of his test

supply chain and logistics issues of bio energy production abstract within the concert of renewable energy technologies bio energy can play a decisive role during the next decades when smartly designed and applied under favorable conditions in this respect efficient and effective supply chain and logistics management represent one key parameter this paper presents a literature review of articles published in english speaking peer reviewed journals from 2000 to 2009 which cover the interface of bio energy production and issues of logistics and supply chain management first the articles are assessed according to descriptive criteria such as journal year of publication and research design applied then issues and challenges of designing and operating biomass chains that secure stable and competitively priced feedstock supply for bio energy plants have been classified 1 into the operations harvesting and collection storage transport and pre treatment techniques as well as 2 into overall supply system design although biomass supply chains for energy use are manifold in terms of size design and functioning most relevant issues regarding supply chain management and logistics of bio energy production are identified the findings are discussed against the backdrop of bio energy as sustainable renewable energy option

contesting legitimacy of voluntary sustainability certification schemes valuation languages and power asymmetries in the roundtable on sustainable palm oil in colombia voluntary certification schemes aimed at assuring producer compliance with a set of sustainability criteria have emerged as market based instruments mbis of sustainability governance however the impacts they tackle can be part of a complex arena of socio environmental conflict where values and powers of business and local actors compete legitimacy of these schemes not only results from compliance by business actors but also depends on acceptance by local actors affected by or resisting the industries that these mechanisms aim to govern this paper explores the influence of different local actors values and powers on legitimacy granting or contestation by local actors during national processes of sustainability criteria development we analyse the case of the roundtable on sustainable palm oil rspo in colombia using an approach that combines concepts of ecological economics and political ecology with the legitimacy literature based on critical sociology in colombia the palm oil industry led the initiative to implement certification under national interpretation of rspo principles and criteria however the national interpretation process revealed power asymmetries among stakeholders and clashes between their different values this resulted in strong contestation of rspo legitimacy by local actors who resist expansion of oil palm cultivation

lessons from first generation biofuels and implications for the sustainability appraisal of second generation biofuels the emergence of second generation 2g biofuels is widely seen as a sustainable response to the increasing controversy surrounding the first generation 1g yet sustainability credentials of 2g biofuels are also being questioned drawing on work in science and technology studies we argue that controversies help focus attention on key often value related questions that need to be posed to address broader societal concerns this paper examines lessons drawn from the 1g controversy to assess implications for the sustainability appraisal of 2g biofuels we present an overview of key 1g sustainability challenges assess their relevance for 2g and highlight the challenges for policy in managing the transition we address limitations of existing sustainability assessments by exploring where challenges might emerge across the whole system of bioenergy and the wider context of the social system in which bioenergy research and policy are done key lessons arising from 1g are potentially relevant to the sustainability appraisal of 2g biofuels depending on the particular circumstances or conditions under which 2g is introduced we conclude that sustainability challenges commonly categorised as either economic environmental or social are in reality more complexly interconnected so that an artificial separation of these categories is problematic

trends and sustainability criteria of the production and use of liquid biofuels abstract environmental impacts associated with the use of fossil fuels rising prices potential limitations in supply and concerns about regional and national security are driving the development and use of biomass for bioenergy biofuels and bioproducts however the use of biomass does not automatically imply that its production conversion and use are sustainable conflicts between various ecosystem services economic production of food fodder and fuels biodiversity social and cultural values etc that are provided by fertile land are increasing as well hence a developed thinking on how to balance between these services is desirable there is a significant amount of information available on biofuels and their sustainability in this paper different initiatives and sustainability criteria for biofuels are presented and assessed 35 criteria were found in emerging sustainability assessment frameworks the majority of 12 criteria were focused on environmental issues 4 were social and only 1 was economic energy balance and greenhouse gas balance were perceived as especially critical social criteria ranked generally low although being perceived as important food security ranked very low

testing for structural breaks trade off between power and spurious effects abstract i argue that in order to test for the effect of the foundation of the federal reserve on the behavior of short term interest rates extending the sample size on either side of the interval 1908 1918 will generate spurious results mankiw miron and weil 1987 1994 do not address data problems pointed out by other authors nor do they take into account some historical events and institutional changes in the new york money market that had an impact on the behavior of short term interest rates given these reasons for restricting the sample size i argue that their monte carlo evidence is largely irrelevant to the issue and that lack of power confirms my claim that no regime change can be detected astride the foundation of the fed

the social cost of labor and project evaluation a general approach abstract this paper presents a general framework for analyzing shadow wages in ldcs we focus on i the differences between the domestic and international prices ii the equilibrating mechanisms in the economy iii the endogeneity of earnings in industry and agriculture iv the consequences of industrial employment creation on agriculture and v the nature of migration and unemployment we identify those reduced form relationships which are central in determining the shadow wage and use them to obtain general formulae for the shadow wage these formulae can be specialized to alternative technological behavioral and institutional settings this yields many new results concerning the relationship between the shadow wage and the market wage also earlier results on shadow wages are derived as special cases of our formulae

the foreign exchange constraint suppression of the trade deficit and the shadow price of foreign exchange in a fix price economy abstract the foreign exchange gap is analysed as a possible feature of a fix price economy the implications of closing the gap by means of import rationing are then discussed finally a set of shadow rates of exchange is derived these shadow prices are conditional on the prevailing regimes and include the paradoxical possibility of a negative shadow rate of exchange

more on the behavior of interest rates and the founding of the fed abstract the paper addresses the issue of the impact of the foundation of the federal reserve system in 1914 on the behavior of short term interest rates empirical evidence is presented showing that no change of regime can be detected in the process governing short term rates in the years straddling the foundation of the fed since the behavior of this process did change in the decade 1910 1920 the paper discusses some historical events and institutional changes in the new york money market that had an impact on the behavior of short term interest rates between 1908 and 1920

ethical and legal challenges in bioenergy governance coping with value disagreement and regulatory complexity the article focuses on the interplay between two factors giving rise to friction in bioenergy governance profound value disagreements e g the prioritizing of carbon concerns like worries over ghg emissions savings over non carbon related concerns and regulatory complexity in terms of regulatory measures and options we present ethical and legal analyses of the current stalemate on bioenergy governance in the eu using two illustrative cases liquid biofuels for transport and solid biomass based bioenergy the two cases disclose some similarities between these two factors but the remaining differences may partly explain or justify contrasting forms of governance while there seems to be no easy way in which the eu and national governments can deal with the multiple sustainability issues raised by bioenergy it is argued that failure to deal explicitly with the underlying value disagreements or to make apparent the regulatory complexity clouds the issue of how to move forward with governance of bioenergy we suggest that governance should be shaped with greater focus on the role of value disagreements and regulatory complexity there is a need for more openness and transparency about such factors and about the inherent trade offs in bioenergy governance

low climate stabilisation under diverse growth and convergence scenarios abstract in the last decade a number of papers have analysed the consequences of achieving the greenhouse gas concentration levels necessary to maintain global temperature increases below 2 c above preindustrial levels most models and scenarios assume that future trends in global gdp will be similar to the growth experienced in the past century which would imply multiplying current output by about 19 times in the 21st century however natural resource and environmental constraints suggest that future global economic growth may not be so high furthermore the environmental implications of such growth depend on how it is distributed across countries this paper studies the implications on ghg abatement policies of low global gdp growth and high convergence levels in gdp per capita across countries a partial equilibrium model poles of the world s energy system is used to provide detailed projections up to 2050 for the different regions of the world the results suggest that while low stabilisation could be technically feasible and economically viable for the world in all the scenarios considered it is more likely to occur with more modest global growth however that will imply higher global abatement costs relative to gdp convergence in living standards on the other hand places greater pressures in terms of the required reduction in emissions in general we find that there are major differences between regions in terms of the size and the timing of abatement costs and economic impact

developing a sustainability framework for the assessment of bioenergy systems the potential for biomass to contribute to energy supply in a low carbon economy is well recognised however for the sector to contribute fully to sustainable development in the uk specific exploitation routes must meet the three sets of criteria usually recognised as representing the tests for sustainability economic viability in the market and fiscal framework within which the supply chain operates environmental performance including but not limited to low carbon dioxide emissions over the complete fuel cycle and social acceptability with the benefits of using biomass recognised as outweighing any negative social impacts this paper describes an approach to developing a methodology to establish a sustainability framework for the assessment of bioenergy systems to provide practical advice for policy makers planners and the bioenergy industry and thus to support policy development and bioenergy deployment at different scales the approach uses multi criteria decision analysis mcda and decision conferencing to explore how such a process is able to integrate and reconcile the interests and concerns of diverse stakeholder groups

optimal investment choice for developing countries rational theory and rational decision making abstract this paper analyzes a key feature of the conceptual process that governments use for making major investment choices in the developing countries both through their direct investment activities and through the special incentives e g credit foreign exchanage and tax subsidies they provide governments typically play a large role in the allocation of investment resources in ldc s consequently the public investment choice process has significant effects on the efficiency of capital formation and on economic growth in developing countries although the feature of the investment choice process on which we focus has important theoretical and practical implications it has so far received little analytical attention

sustainability of biofuels in latin america risks and opportunities several latin american countries are setting up biofuel programmes to establish alternative markets for agricultural commodities this is mainly triggered by the current success of brazilian bioethanol production for the domestic market and for export furthermore the global biofuel market is expected to increase due to ambitious biofuel programmes in the eu and in the usa colombia venezuela costa rica and guatemala are focusing on bioethanol production from sugarcane whereas biofuel production in argentina is based on soy biodiesel recent developments of the biofuel sector take place extremely rapid especially in argentina which became one of the five largest biodiesel producers in the world in 2008 till date no specific biofuel sustainability certification systems have been implemented in latin american as well as on global level this fact and the predominant use of food crops for biofuel production raise concerns about the sustainability of biofuel production related to environmental and social aspects this paper provides an overview of the hotspots of conflicts in biofuel production in latin america it investigates presently available sustainability tools and initiatives to ensure sustainable biofuel production in latin america finally it provides an outlook on how to integrate sustainability in the latin american biofuel sector

sustainable supply chain management when focal firms are complex a network perspective the purpose of the paper is to generate an understanding of the prerequisites for sustainable supply chain management a common tendency in the literature is to see sustainable supply chain management as something that is undertaken by a focal firm at the end of the chain even though many scholars point to the need for cooperative approaches focal firms are still considered to manage supply chains from one fixed and coherent vantage point the managerial outlook of the focal firm itself understood as a structurally coherent top down controlled unit through an illustration from the swedish retail sector we argue that such a vantage point is problematic we suggest a deeper analysis of focal firms and sustainable supply chain management in terms of a network perspective employed mainly in the industrial marketing and purchasing imp literature the adopted network perspective recognizes both internal and external complexity of sustainable supply chain management implying for example difficulties to control entire organizations and the existence of multiple supply chains to manage it is also suggested that sustainable supply networks may be a viable concept to use when dealing with sustainability issues related to production since it relates sustainability in the supply chain to the more general responsibility context of firms

biofuel developments in mozambique update and analysis of policy potential and reality abstract climate change rising oil prices and concerns about future energy supplies have contributed to a growing interest in using biomass for energy purposes several studies have highlighted the biophysical potential of biofuel production on the african continent and analysts see mozambique as one of the most promising african countries favorable growing conditions and the availability of land water and labor are mentioned as major drivers behind this potential moreover the potential of biofuel production to generate socio economic benefits is reflected in the government s policy objectives for the development of the sector such as reducing fuel import dependency and creating rural employment this article provides an overview of biofuel developments in mozambique and explores to what extent reality matches the suggested potential in the country we conclude that biofuel developments mainly take place in areas near good infrastructure processing and storage facilities where there is skilled labor available and access to services and goods moreover our analysis shows the need to timely harmonize current trends in biofuel developments with the government s policy objectives as the majority of existing and planned projects are not focusing on remote rural areas and in absence of domestic markets principally target external markets

european union leadership in biofuels regulation europe as a normative power the rapid emergence of the european union eu as a leader in global environmental politics has led many scholars to argue in favour of the eu being a normative power in international relations this paper critically examines the eu s biofuels policy and evaluates whether its attempts to lead by example and shape international practice in this field could support such arguments europe s biofuel policies are evaluated through a sustainable development lens so as to determine the extent to which it has embraced a holistic approach to sustainability while not dismissing that the identity of the eu is indeed an explanatory factor and that normative intentions may well be regarded as a motivating force this study argues that an interest based perspective on international environmental regulation offers a supplementary view of how an actor s preferences for an international regime are shaped by erecting barriers aimed at shielding its own inefficient domestic biofuels production the eu is in essence placing trade competitiveness and economic growth above environmental protection thus permitting sustainability concerns to be addressed only in part

institutional emergence in an era of globalization the rise of transnational private regulation of labor and environmental conditions1 why have systems of transnational private regulation recently emerged to certify corporate social and environmental performance different conceptions of institutional emergence underlie different answers to this question many scholars argue that firms create certification systems to solve problems in the market a view rooted in a conception of institutions as solutions to collective action problems the author develops a different account by viewing institutions as the outcome of political contestation and by analyzing conflict and institutional entrepreneurship among a wide array of actors using a comparative case study design the analysis shows how these arguments explain the formation of social and environmental certification associations both theoretical approaches are needed but strong versions of the market based approach overlook an important set of dynamics that the author calls the political construction of market institutions the analysis shows how both problem solving in markets and

biofuels development in sub saharan africa are the policies conducive this paper analyses national regional and international biofuels policies and strategies to assess whether these policies promote or undermine the development of biofuels sector in africa despite having a huge comparative advantage in land labour and good climatic conditions favourable for the growing of energy crops few countries in sub saharan africa have included biofuels strategies in their energy or national development policies further results show that while developed countries commit huge financial resources for research technology development and the provision of tax incentives to both producers and consumers there is little government support for promoting biofuels in africa although the consequences of biofuels on food supply remain uncertain the mandatory blending of biofuels with fossil fuels by industrialized countries will create demand for land in africa for the growing of energy crops for biofuels this paper urgently calls upon national governments in sub saharan africa to develop appropriate strategies and regulatory frameworks to harness the potential economic opportunities from biofuels sector development while protecting the environment and rural communities from the adverse effects of land alienation from the mainstream agriculture towards the growing of energy crops for biofuels at the expense of traditional food crops

the geographic and sectoral patterns of large scale farmland investments in sub saharan africa following the food and energy price crises of the mid 2000s sub saharan africa has become one of the largest recipients for large scale farmland investments while much has been written on the phenomenon scant reliable empirical evidence is available as to the precise geographic and sectoral patterns and underlying drivers employing strict data quality requirements this paper addresses these knowledge gaps by analyzing 563 farmland projects that have been established between 2005 and 2013 in sub saharan africa findings show that the investment intensity and associated risks are not geographically uniform moreover the study highlights a number of popular misconceptions regarding investor origin and their sectoral interests and motives

market based governance for sustainability in value chains conditions for successful standard setting in the palm oil sector abstract current production and consumption patterns remain unsustainable global economic growth reaches planetary boundaries and puts increasing pressure on the world s natural resources whereas most economic actors just react to environmental pressures proactive market actors and other non governmental organisations e g greentec firms or fair trade organisations turn them into market opportunities or even create standards or certification schemes as promising problem solving market instruments in global value chains however how legitimate are standards and certification schemes developed by collaborating non state actors for sustainability in global value chains what are conditions for the success of those market based governance mechanisms this paper discusses the legitimacy and effectiveness of standard setting in the case of palm oil and focuses on the roundtable of sustainable palm oil rspo as the first global standard setting initiative in this respect conditions for the success of sustainability standard setting in global value chains are identified based on the concept of non state market driven nsmd governance based on literature review and expert interviews on standard setting results from the case study on rspo highlight strengths and weaknesses of its standard setting process in the light of increasing market demand for palm oil

do no harm risk perceptions in national bioenergy policies and actual mitigation performance this paper investigates how risks are anticipated in national bioenergy policies and in which way related expectations that harms can be prevented or mitigated have actually been met the paper draws on the national biofuel policies of ten countries and the eu selected to represent a diverse sample of regions producers and consumers and pioneers and latecomers it proceeds in two steps firstly it identifies three risk categories most frequently mentioned across the investigated national policies secondly it conducts a systematic review of available empirical research about biofuels effects in these risk categories findings are discussed regarding the empirical conditions under which related expectations to do no harm have materialized or failed and concerning the challenges of risks perception and management in actual policies we observe issues of crop selection and inadequate sectoral governance of biofuels but also challenges of large scale modes of intensive production effective risk mitigation was often the result of risk adverse choices by contract farmers engaged in biofuels production national policy documents have insufficiently conceptualized do no harm concepts and strategies in place to address these performance issues while remaining silent on the particular risk governance and accountability framework that keeps track of actual developments commitments and responsibilities

the emergence of southern standards in agricultural value chains a new trend in sustainability governance abstract the objective of this paper is to understand and trace the emergence of southern standards in global agricultural value chains while the trend towards private standards established by developed country or northern actors has received significant attention in the literature recently an emergent counter trend can be observed which manifests in the development of standards by southern producer country actors this may be attributed to the perceived lack of legitimacy of global standards especially from a southern perspective the paper therefore applies a legitimacy perspective to analyse the emergence of new southern standards in indonesian and malaysian palm oil brazilian soy and south african fruit production the analysis reveals that southern standards both target different audiences to obtain legitimacy and rely on different sources of legitimacy as compared to established northern standards this is done explicitly in order to create cognitive and moral distance to northern standards and ultimately to reclaim the issue areas occupied by northern standards the paper discusses and reflects on the implications of the emergence of southern standards for sustainability governance and concludes with the identification of future research opportunities on southern standards

a review of social sustainability considerations among eu approved voluntary schemes for biofuels with implications for rural livelihoods the rapid expansion of biofuel production and consumption has raised concerns over the social and environmental sustainability of biofuel feedstock production processing and trade the european union eu has thus balanced its commitment to biofuels as one option for meeting its renewable energy targets with sustainability criteria for economic operators supplying biofuels to member states seven voluntary eu sustainability schemes were approved in july 2011 as a means to verify compliance while mandated sustainability criteria have a strong environmental focus a number of these voluntary schemes have social sustainability as a significant component of the requirements put forward for achieving certification as several of these voluntary schemes are incipient thereby limiting evidence on their effectiveness in practice this analysis is based on a comparative analysis of the substantive content or scope of these schemes and the likely procedural effectiveness of the same findings show that while some schemes have considerable coverage of social sustainability concerns poor coverage of some critical issues the presence of schemes lacking any social sustainability requirements and gaps in procedural rules are likely to undermine the likelihood that social sustainability is achieved through these schemes or the eu sustainability policies lending credibility to them

what is ecological economics ecological economics addresses the relationships between ecosystems and economic systems in the broadest sense these relationships are the locus of many of our most pressing current problems i e sustainability acid rain global warming species extinction wealth distribution but they are not well covered by any existing discipline environmental and resource economics as it is currently practiced covers only the application of neoclassical economics to environmental and resource problems ecology as it is cur rently practiced sometimes deals with human impacts on ecosystems but the more common tendency is to stick to natural systems ecological economics aims to extend these modest areas of overlap it will include neoclassical environmental economics and ecological impact studies as sub sets but will also encourage new ways of thinking about the linkages between ecological and economic systems we have chosen the name ecological economics for this area of study because it implies a broad ecological interdisciplinary and holistic view of the problem of studying and managing our world the earth from space cover of the journal reflects this global holistic perspective we did not intend to imply with the ordering of the two words in the title that the journal is mainly an economics journal it is intended to be a new approach to both ecology and economics that recognizes the need to make economics more cognizant of ecological impacts and dependencies the need to make ecology more sensitive to economic forces incentives and constraints and the need to treat integrated economic ecologic systems with a common but diverse set of conceptual and analytical tools there was much discussion of other possible names such as economic ecology or ecology and economics or some conjoining of the two words that to me end up being confusing tongue twisters like ecolnomics or econology but ecological economics seemed to get closest to the mean ing we desired while still being evocative to the uninitiated
