wheat from chaff meta analysis as quantitative literature review abstract this paper presents and develops a quantitative method of literature reviewing and evaluating empirical research meta regression analysis or mra economics is theory driven yet we must learn empirically if economics is to advance mra offers a more objective statistical method to summarize our empirical knowledge and to explain the wide study to study variation in economic research mra is used to assess the evidence for ricardian equivalence and its findings are contrasted to those of conventional narrative review furthermore mra establishes a platform from which to distinguish genuine empirical effect from the exploitable specification error that infests applied econometrics

resource degradation and adoption of land conservation technologies in the ethiopian highlands a case study in andit tid north shewa abstract this paper reports results from a study of resource degradation and conservation behavior of peasant households in a degraded part of the ethiopian highlands peasant households choice of conservation technologies is modeled as a two stage process recognition of the erosion problem and adoption and level of use of control practices an ordinal logit model is used to explain parcel level perception of the threat of the erosion problem and the extent of use of conservation practices results show the importance of perception of the threat of soil erosion household land and farm characteristics perception of technology specific attributes and land quality differentials in shaping conservation decisions of peasants furthermore where poverty is widespread and appropriate support policies are lacking results indicate that population pressure per se is unable to encourage sustainable land use the challenge of breaking the poverty environment trap and initiating sustainable intensification thus require policy incentives and technologies that confer short term benefits to the poor while conserving the resource base

the political economy of rural property rights and the persistence of the dual economy abstract rural areas often have more than one regime of property rights and production large private property farms owned by powerful landowners coexist with subsistence peasants who farm small plots with limited property rights at the same time there is broad consensus that individual well specified and secure property rights over land improve economic outcomes if property rights in land are so beneficial why are they not adopted more widely i put forward a theory according to which politically powerful landowners choose weak property rights to impoverish peasants and force them to work for low wages moreover because weak property rights force peasants to stay in the rural sector protecting their property the incentives to establish poor property rights are especially salient when peasants can migrate to an alternative sector such as when urban wages increase with industrialization

going digital credit effects of land registry computerization in india digitization of land records represents a unique way to test for credit supply effects of improved land administration information over time the authors exploit variation in the timing of the shift from manual to digital operation of andhra pradesh s 387 sub registry offices during the state wide rollout of this intervention from 1999 to 2005 data on credit disbursement and registered mortgages for the 1995 2007 period point to significant though quantitatively modest increases in credit access in urban areas institutional factors allow the authors to explain these results

flood risk land use and private participation in embankment maintenance in indian sundarbans this paper analyzes the complementarities between land productivity and conservation investments in the context of river embankment maintenance in the indian sundarbans the study finds that households whose principal occupation is aquaculture commit more resources to embankment maintenance relative to those in non aquaculture employment while conservation efforts are greater in all types of aquaculture plots irrespective of distance from the embankments such efforts unambiguously decrease for agricultural plots that are located at a distance from the embankments private returns to traditional aquaculture are much higher than returns to agriculture enabling aquaculture households in invest in managing their local public good however there is evidence of free riding in canal based aquaculture when multiple users draw water from a single source head enders with greater wealth as well as intense social networks tend to free ride while tail enders with less land holdings contribute more towards canal maintenance furthermore public intervention in embankment maintenance may be crowding out private efforts thus in primarily agricultural areas productivity enhancing policies like adoption of salt tolerant crops with supportive extension activities may be more efficient than policies that fully subsidize public good maintenance

the economic effects of land registration on smallholder farms in kenya evidence from nyeri and kakamega districts effects of land registration and title on security of tenure use of formal credit crop yields and land concentration are analyzed from household and plot data in four kenyan sites results indicate that the registration and titling program had a weak impact on perceived land rights of farmers credit use and terms crop yields or concentration of land holdings the conclusion is that titles are acquired for enhancing security of rights rather than for increasing agricultural production scarce government resources are best targeted towards providing better infrastructure and market opportunities which should also foster a greater demand for titling

tenure security and land related investment evidence from ethiopia the authors use a large data set from ethiopia that differentiates tenure security and transferability to explore determinants of different types of land related investment and its possible impact on productivity while they find some support for endogeneity of investment in trees this is not the case for terraces transfer rights are unambiguously investment enhancing the large productivity effect of terracing implies that even where households undertake investments to increase their tenure security this may not be socially efficient in ethiopia government action to increase tenure security and transferability of land rights can significantly enhance rural investment and productivity

land tenure security and investment does strength of land right really matter in rural burkina faso abstract the causal relationship between land tenure security and agricultural investment plays a crucial role in the process of rural development land property rights are key determinants for reducing poverty through agricultural productivity natural resource management and socio economic inequalities growing competition for land access increases the sensitivity in land socio economic stakes and related policies in developing countries this paper analyzes the impacts of land rights on land related investment in rural burkina faso we use rural representative panel data and appropriate methods the two stage conditional maximum likelihood approach is used for dealing with endogeneity while the generalized structural equation model allows us to control for random effects we show that stronger land rights increase land attached investment and land investment has positive and negative effect on stronger and weaker land rights respectively in rural burkina faso our study also finds that women and immigrants have less land rights than men and natives respectively our contribution to related literature includes the use of rigorous process of hierarchy in land rights the close link of the results with land right strength is of great interest for cautious practitioners in land tenure and investment moreover our results imply that a gain of efficiency can be achieved from combining practices in land tenure and investment

identifying and addressing land governance constraints to support intensification and land market operation evidence from 10 african countries beyond concerns about agricultural productivity growth issues of land governance have attracted global interest as demand for land acquisition by outsiders has increased rapidly but most of the transfers failed to live up to expectations and instead disrupted local livelihoods we use the land governance assessment framework to identify key conceptual issues and identify how land governance in 10 african countries compares to global good practice results point towards weak protection of rights in practice large gaps in female land access and limited outreach and effectiveness of institutions to record rights and adjudicate disputes we note that programs to improve performance along these lines had significant impact in other contexts suggesting that efforts to improve land governance will be warranted and should be closely monitored and evaluated in an effort to identify models suited to african conditions and assess their impact and interaction with other factor markets

technical trading rules in the european monetary system abstract using genetic programming we find trading rules that generate significant excess returns for three of four ems exchange rates over the out of sample period 1986 1996 permitting the rules to use information about the interest rate differential proved to be important the reduction in volatility resulting from the imposition of a narrower band may reduce trading rule profitability our results cannot be duplicated by commonly used moving average rules filter rules or by two rules designed to exploit known features of target zone rates there is no evidence that the excess returns are compensation for bearing systematic risk

is land titling in sub saharan africa cost effective is land titling in sub saharan africa cost effective a cost benefit analysis suggests that the current system of formal titling should not be extended in rural madagascar and that any new system of land registration would have to be quite inexpensive to be worthwhile indeed establishing a modern property rights system without legally recognizing informal rights may expand the scope for rent seeking thus creating additional insecurity atwood 1990 purchasing a titled plot without easily being able to update the name on the document exposes the buyer to the risk that a relative of the seller sharing the family name might subsequently claim the plot or challenge the transfer analyses omitted here for brevity indicate that there is no significant advantage to owning titled land in terms of a household s access to formal credit after controlling for the household s landholdings within the mailles such land being much more likely to be titled and titled plots are no more likely to be used as collat

do overlapping property rights reduce agricultural investment evidence from uganda the need for land related investment to ensure sustainable land management and increase productivity of land use is widely recognized however there is little rigorous evidence on the effects of property rights for increasing agricultural productivity and contributing toward poverty reduction in africa whether and by how much overlapping property rights reduce investment incentives and the scope for policies to counter such disincentives are thus important policy issues using information on parcels under ownership and usufruct by the same household from a nationally representative survey in uganda the authors find significant disincentives associated with overlapping property rights on short and long term investments the paper combines this result with information on crop productivity to obtain a rough estimate of the magnitudes involved the authors make suggestions on ways to eliminate such inefficiencies

partial land rights and agricultural outcomes evidence from thailand to disentangle the issue concerning which dimensions of land rights among security tradability and pledgeability affect agricultural outcomes this paper exploits a unique partial land rights entitlement program in thailand that guarantees only security allows a limited access to credit and prohibits any land sale based on an instrumental variables strategy i find that the entitlement increases 1 second rice but not major rice productivity 2 land use intensity and 3 land related investment and leads to 4 better soil quality this suggests that the security dimension alone can play an important role in improving farm activities

communal land and agricultural productivity this paper quantifies the aggregate impact of communal land tenure ar rangements that prevail in sub saharan africa such tenure regimes limit land transfer ability by prohibiting sales subjecting rented out land to the risk of expropriation and redistributing it to existing farmers in a progressive fashion we use a general equilibrium two sector selection model featuring agents heterogeneous in skills to compute the result ing occupational and operational choices as well as land allocations the quantification of the model is based on policies deduced from ethiopia in the sub saharan african context we find that such policies substantially dampen nominal agricultural relative to non agricultural productivity by 25 real relative agricultural productivity however only falls by 4 since cross sectoral terms of trade adjust strongly with excess agricul tural employment only amounting to some 1 5 percentage points the loss in gdp is small about 2 that serves as a reminder that ostensibly highly distortionary policies need not have substantial bite when individuals strategically adjust to them and equilib rium prices adapt for example the model predicts that at given prices 62 of farmers in an economy such as ethiopia would leave farming if tenure were secured casting land insecurity as a major obstacle yet only 9 would actually switch sectors after price adjustments are factored in

land markets property rights and deforestation insights from indonesia summary we examine the emergence of land markets and their effects on forest land appropriation by farm households in jambi province sumatra using micro level data covering land use and land transactions for a period of more than 20 years 1992 2015 based on a theoretical model of land acquisition by a heterogeneous farming population different hypotheses are developed and empirically tested farm households involved in forest land appropriation differ from those involved in land market purchases in terms of migration status and other socioeconomic characteristics in principle these differences provide opportunities for market induced deforestation however the appropriated forest land is not extensively traded which we attribute to the lack of de jure property right protection and the resulting undervaluation in the market while the de facto property right protection under customary law provides sufficient security within the village community the sense of external tenure security is low when the land cannot be formally titled clearing forests for trading in the land market is therefore financially less lucrative for farm households than engaging in own cultivation of plantation crops such as oil palm and rubber we conclude that land markets did not have significant effects on deforestation on the other hand the emergence of land markets alone has also not been able to deter forest appropriation by local farm households

environmental and gender impacts of land tenure regularization in africa pilot evidence from rwanda although increased global demand for land has led to renewed interest in african land tenure few models to address these issues quickly and at the required scale have been identified or evaluated the case of rwanda s nation wide and relatively low cost land tenure regularization program is thus of great interest this paper evaluates the short term impact some 2 5 years after completion of the pilots undertaken to fine tune the approach using a geographic discontinuity design with spatial fixed effects three key findings emerge from the analysis first the program improved land access for legally married women about 76 percent of married couples and prompted better recordation of inheritance rights without gender bias second the analysis finds a very large impact on investment and maintenance of soil conservation measures this effect was particularly pronounced for female headed households suggesting that this group had suffered from high levels of tenure insecurity which the program managed to reduce third land market activity declined allowing rejection of the hypothesis that the program caused a wave of distress sales or widespread landlessness by vulnerable people implications for program design and policy are discussed

tenure security human capital and soil conservation in an overlapping generation rural economy we develop an overlapping generation model of rural agricultural households to examine whether tenure security and subsistence needs influence the choice between unexploited topsoil and investment in children s human capital as the mode of transfer of wealth a unique dataset from bangladesh finds that tenure security is associated with greater topsoil conservation and lower human capital investment therefore there exists a tradeoff between these two modes of transfer we suggest that increased public expenditure on schooling which substitutes private expenditure may lower the pressure on land and soil resources

the economic effects of the abolition of serfdom evidence from the russian empire we document substantial increases in agricultural productivity industrial output and peasants nutrition in imperial russia as a result of the abolition of serfdom in 1861 before the emancipation provinces where serfs constituted the majority of agricultural laborers lagged behind provinces that primarily relied on free labor the emancipation led to a significant but partial catch up better incentives of peasants resulting from the cessation of ratchet effect were a likely mechanism behind a relatively fast positive effect of reform on agricultural productivity the land reform which instituted communal land tenure after the emancipation diminished growth in productivity in repartition communes

indigenous land rights in sub saharan africa appropriation security and investment demand abstract we discuss the links between rights appropriation tenure security and investment demand in sub saharan africa common assertions regarding indigenous tenure are 1 a insecurity of tenure leads to suboptimal investment incentives and 2 b appropriation of land rights in the public domain is rent dissipating we argue that land use and investment decisions among african farmers often have two motives productivity and rights appropriation the usual assertions thus seem contradictory we offer a conceptual model to show that indigenous tenure may provide equal or higher investment incentives than private rights and may promote modes of rights appropriation that are productive rather than wasteful

tenure security investment and productivity in gambian agriculture a generalized probit analysis the determinants of investment input use and productivity are investigated under customary tenure in peri urban areas of the gambia a structural model is specified to investigate the role of tenure security on farm investments and input use and thereby on yield testing of the structural form hypotheses requires simultaneous equation estimation containing both continuous and discrete endogenous variables the model is estimated as a feasible generalized least squares amemiya s generalized probit some of the positive relationships hypothesized between tenure security investment and yields are corroborated in particular tenure security is found to enhance long term investments which in turn enhance yields

property rights and water access evidence from land titling in rural peru summary insecure land tenure and property rights are an impediment to infrastructure access and services for households in many developing countries this paper explores whether alleviating this impediment through a land titling program in rural peru is associated with improvements in household water sources as well as sanitation and electricity services the economics literature on the links between property rights and investment decisions has amassed yet due to the necessity of water for life the high fixed costs associated with water infrastructure construction and the positive externalities that can result from water provision it is not obvious how water services might respond to land tenure improvements utilizing the phased in program timing in a quasi experimental design we exploit the differences in implementation timing across space in conjunction with the differences in program impact across households that held property titles prior to the project and those that did not results from this modified difference in differences method indicate that land titling is associated with small in magnitude but statistically significant increases in water access larger gains in sanitation and electricity services are found we investigate the channels through which this improved access occurs and find evidence of investments in all three services via either government or water utilities we find evidence of individual household investment only in the case of sanitation taken together these results indicate that land titles are important but not sufficient to increase access to water and other services

gender differences in the relationship between land ownership and managerial rights implications for intrahousehold farm labor allocation abstract recent research has increased interest in the intersection of land tenure and gender roles in african agriculture while formalization of land ownership has been found to have important gender impacts time use and management remain critical to both the productivity of agricultural operations as well as the welfare of household members thus it is important to understand how gender intersects with the relationship between the ownership and operation of plots we use plot level data from nationally representative household surveys in ethiopia and malawi to characterize the structure sole male sole female or joint and domain plot ownership plot management or output management of control over land in each household we then answer the following research questions 1 are there any gender gaps in the degrees of the concordance among different domains of controls and 2 how does the structure of ownership and managerial rights affect labor allocations on plots we find that for both males and females sole managerial rights are most likely to occur in plots owned exclusively by either gender however on jointly owned plots instances of sole planting rights are almost exclusively male we also find that while females supply more of their own labor to plots they control the pattern of own gender bias in labor allocation varies with each structure domain combination the heterogeneity suggests gender inequality analyses related to land rights are sensitive to the choice of domain of control

impacts of low cost land certification on investment and productivity new land reforms are again high on the policy agenda and low cost propoor reforms are being tested in poor countries this article assesses the investment and productivity impacts of the recent low cost land certification implemented in the tigray region of ethiopia using a unique household and farm plot level panel data set with data from before and up to eight years after the reform alternative econometric methods were used to test and control for endogeneity of certification and for unobserved household heterogeneity significant positive impacts were found including effects on the maintenance of soil conservation structures investment in trees and land productivity copyright 2007 oxford university press

land transfer in rural china incentives influencing factors and income effects land transfer incentives and their effect on farmers income in developing countries have been widely examined in the literate but little is known about the driving mechanism of rural household in

the profits of power land rights and agricultural investment in ghana we examine the impact of ambiguous and contested land rights on investment and productivity in agriculture in akwapim ghana we show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights and that as a consequence they invest more in land fertility and have substantially higher output the intensity of investments on different plots cultivated by a given individual corresponds to that individual s security of tenure over those specific plots and in turn to the individual s position in the political hierarchy relevant to those specific plots

new ways to assess and enhance land registry sustainability evidence from rwanda summary rwanda has recently implemented a nation wide program of first time land regularization ltr that many believe set new standards for the region we use administrative data combined with household survey and program rollout information to explore sustainability of the infrastructure created in this process including the impact of public efforts to increase registration of subsequent transactions we find that the program provided significant benefits in terms of gender equality and credit access while opening up new opportunities in terms of land taxation or land use planning but that high level of rural informality may undermine these in the medium to long term while public efforts to decentralize service provision helped to significantly reduce informality additional efforts are likely to be needed to ensure sustainability of the registry we discuss how rwanda can further move in this direction and draw out implications for other countries considering first time adjudication and registration of property rights

land tenure systems and their impacts on agricultural investments and productivity in uganda this article provides an empirical analysis of the impact of different tenure systems mailo customary and public land on agricultural investment and productivity in central uganda a major hypothesis tested is that land investments and practices may have both economic and tenure security implications the results indicate that coffee planting is used by farmers to enhance tenure security while fallowing is practised to a greater extent by farmers on more secure holdings this supports the notion that farmers consider tenure implications when making investments and that different tenure systems do not inhibit the promotion of tree planting investment tenure had no impact on the productivity of crop farming

land tenure and agricultural productivity in africa a comparative analysis of the economics literature and recent policy strategies and reforms summary this paper examines the convergence and divergence of results from economic studies of the relationships between land tenure security and agricultural productivity in africa and how these results have been incorporated into recent agricultural poverty alleviation and land policy documents the paper finds that there are both areas of convergence and divergence in the economics literature similarly the attention given to land tenure and its perceived effects on productivity varies considerably in the policy literature the significant heterogeneity in findings itself suggests that policy responses must pay attention to local context and the overarching macro and sectoral conditions within which tenure systems operate

north south interactions in the presence of trade in environmental permits a structuralist investigation this article develops a structuralist framework to analyse a world where production requires emission permits international agreements bind northern output whilst leaving room for the south under the principle of common but differentiated responsibilities act i considers the effects of reducing northern output through tighter emission regulations in the short run traditional structuralist results such as a negative effect on southern terms of trade and accumulation follow in the long run the impact of northern regulation is bottled up within that region this latter property vanishes once act ii allows for the creation of international permit markets permit trade relaxes the northern output constraint whilst also establishing a channel through which the north directly influences southern permit prices the result in the short run is to reverse the effects of tighter northern regulation on relative southern terms of trade and accumulation which now increase in the long run international permit trade leads to increased variability in the 1 global distribution of capital in response to tighter northern regulation and 2 intensity of northern emissions in response to tighter southern regulation thus globalised permit exchanges generate new trade offs between the global distribution of capital and environmental efficiency

is land titling in sub saharan africa cost effective evidence from madagascar formalizing land rights has been promoted as a way to encourage agricultural investment and stimulate land markets yet little is known about the benefits of such policies in sub saharan africa where the preconditions for success are less favorable the analysis uses a large sample of plots from an intensively titled rice growing area of madagascar and compares land specific investments land productivity and land values for titled and untitled plots cultivated by the same household having a title has no significant effect on plot specific investment and correspondingly little effect on land productivity and land values these results are broadly consistent with a simulation of a theoretical model of investment under expropriation risk calibrated to the same data a cost benefit analysis suggests that the current system of formal titling should not be extended in rural madagascar and that any new system of land registration will have to be quite inexpensive to be worthwhile

land tenure climate and risk management abstract we analyze to what extent climate conditions affect the prevalence of sharecropping as a form of traditional land tenure we investigate how sharecropping tenure is related to climate risk and how it interacts with fertilizer use and livestock ownership that both influence production risk we first develop a stylized theoretical model to illustrate the role of climate for land tenure and production our empirical analysis is based on more than 9000 households with considerable heterogeneity in climate conditions across several african countries we find that farmers in areas with low precipitation are more likely to be sharecroppers we further find evidence for risk management interaction effects as sharecropping farmers are less likely to own livestock and more likely to use fertilizer in economies where formal kinds of insurance are unavailable sharecropping thus functions as a form of insurance and reduces the need for potentially costly risk management strategies

tenure security resource poverty public programs and household plot level conservation investments in the highlands of northern ethiopia land degradation poses a serious problem for the livelihoods of rural producers furthermore there is rarely enough private investment taking place to commensurate the scale of the problem this article examines the role of tenure insecurity resource poverty risk and time preferences and community led land conservation on differentiated patterns of household investment in land conservation in northern ethiopia we control for biophysical household characteristics market access conditions and village level factors investments in soil bunds and stone terraces are specifically studied so as to capture the link between these various factors and the durability of conservation investments we introduce the distinction between the determinants of the decision to invest and how much to invest in conservation regression results show that publicly led conservation programs seem to significantly stimulate private investment a host of plot level variables and household perceptions of returns on conservation investments expressed in terms of perceived improvements in land quality and increased crop yields were found to be critical to the decision to invest and intensify soil conservation the evidence on the significance of households attitudes toward risk aversion suggests the important role of risk and the household s risk bearing capacity in the decision to intensify conservation measures at the same time tenure security indicators and households resource endowments resource poverty had weaker effects in increasing willingness to invest and the level of investment made the policy implications of these results point to the importance of agricultural research and extension efforts that target technologies which reduce household risk and poverty while enabling sustainable investments in conservation measures by individual households

entitled to work urban property rights and labor supply in peru this brief summarizes the results of a gender impact evaluation study entitled entitled to work urban property rights and labor supply in peru new legal rights were issued in 1996 project teams providing titling service through 2003 in peru the study observed that between 1996 and 2003 the peruvian government issued property titles to over 1 2 million urban households the largest titling program targeted at urban squatters in the developing world this paper examines the labor market effects of increases in tenure security resulting from the program pre program squatters in program neighborhoods were significantly more likely to report improved tenure security by 60 percent similarly program participants were 18 8 percentage points less likely to report a high likelihood of eviction or invasion and 18 8 percentage points more likely to report that their dwelling was currently very secure from eviction or invasion the likelihood of working inside the home significantly falls by 11 6 percentage points for the average squatter family with two program periods

investment in soil conservation in northern ethiopia the role of land tenure security and public programs abstract a double hurdle statistical analysis of 250 farms in the tigray region of ethiopia reveals different causal factors for soil conservation adoption versus intensity of use farmers reasons for adopting soil conservation measures vary sharply between stone terraces and soil bunds long term investments in stone terraces were associated with secure land tenure labour availability proximity to the farmstead and learning opportunities via the existence of local food for work ffw projects by contrast short term investments in soil bunds were strongly linked to insecure land tenure and the absence of local food for work projects public conservation campaigns on private plots reduced adoption of both stone terraces and soil bunds whereas capacity factors largely influenced the adoption decision expected returns carried more influence for the intensity of stone terrace adoption measured as metres of terrace per hectare more stone terracing was built where fertile but erodible silty soils in higher rainfall areas offered valuable yield benefits intensity of terracing was also greater in remote villages where limited off farm employment opportunities reduced construction costs these results highlight the importance of the right kind of public interventions direct public involvement in constructing soil conservation structures on private lands appears to undermine incentives for private conservation investments when done on public lands however public conservation activities may encourage private soil conservation by example secure land tenure rights clearly reinforce private incentives to make long term investments in soil conservation

expected failures and unexpected successes of land titling in africa abstract the imposition of market oriented economic reforms throughout africa in the 1990s has sparked renewed debate over the desirability of state sponsored land titling programs proponents argue that land titling is an essential foundation for economic growth opponents contend that titling programs are unnecessary and premature at best or detrimental at worst this paper addresses these concerns through an examination of cameroon s 1974 lands ordinance using both quantitative and qualitative data we find that the 1974 lands ordinance has not introduced western style private property rights in cameroon s agrarian sector nevertheless the ordinance is not irrelevant to rural farmers rural farmers have used the ordinance to obtain concrete boundary markers on their land enhancing their tenure security in addition administrators have used the ordinance to register underdeveloped land reducing the contradictions between state law and customary law these findings suggest that policy makers could fruitfully redesign their land tenure policies to render them more attractive to rural farmers and thereby give the state a more constructive role in enhancing tenure security and in promoting economic growth

land tenure security and investment incentives puzzling evidence from burkina faso abstract the commonsense logic associating higher land security and higher incentives to invest has been recently called into question in the case of african agriculture to be meaningful empirical tests have to be carefully designed so as to take account of the possible endogeneity of the land rights variable this is done in this paper by applying suitable econometric methods to the original data collected in burkina faso the results obtained cast doubt on the existence of a systematic influence of land tenure security on investment by reviewing the justifications for scepticism in the recent literature we are able to conclude that the traditional village order where it exists provides the basic land rights required to stimulate small scale investment

the roles of land tenure reforms and land markets in the context of population growth and land use intensification in africa this article reviews the past and potential future roles of land tenure reforms and land markets in sub saharan africa ssa as responses to population growth in the process of land use intensification and livelihood transformation the farm size distribution and the existence of an inverse relationship ir between farm size and land productivity in ssa and the implications of this relationship for efficiency and equity are investigated more secure property rights and removal of restrictions on land markets have the potential to create both efficiency and equity benefits but there are high risks of elite capture of large land areas with inefficient and inequitable outcomes this situation is the case not only in land abundant areas but also in urban and peri urban areas where increasingly larger proportions of people will make their living increasing population pressure in densely populated rural areas contributes to more rapid rural urban migration and creating alternative livelihood opportunities for the migrating youth population is essential to achieving economic development with social stability

land redistribution tenure insecurity and intensity of production a study of farm households in southern ethiopia this study analyzes the determinants of land tenure insecurity and its impact on intensity of use of purchased farm inputs among households in southern ethiopia seventeen percent of the households stated that they were tenure insecure the feeling of tenure insecurity could be caused by the land redistribution policy in ethiopia where household size has been the main criterion used for land allocation after the land reform in 1975 this would imply that land rich households should be more tenure insecure alternatively the local power structure may be strong enough to counter this and cause the land rich who are also likely to be influential to be able to protect their land rights the analysis revealed that in the overall sample relative farm size was not significantly correlated with tenure insecurity when testing for each site however we found that in four of the sites per capita farm size was positively associated with tenure insecurity while in five other sites it had a significant negative association this may be due to local historical cultural and demographic differences giving way to differences in the effects of the redistribution policy and the local power structure on tenure insecurity we assessed the impact of tenure insecurity on the intensity of use of purchased farm inputs the tenure insecurity variable was insignificant farmers in areas with a positive correlation between farm size and tenure insecurity were more likely to purchase farm inputs larger farms were more likely to use purchased inputs but this effect was lower in areas with a positive correlation between farm size and tenure insecurity poverty and subsistence constraints may explain this absence of higher intensity of use of purchased inputs on small farms by contrast the land redistribution policy may have improved small farms access to purchased farm inputs text of abstract

land tenure and investment incentives evidence from west africa abstract the existing literature on the relationship between property rights in land and agricultural investment in africa has given results that are often confusing and contradictory i make two clarifying contributions to this literature first i pull together existing studies and investigate whether the results they find have been affected by research methods or local contexts studies with small sample sizes those that use binary investment measures and those that control for household fixed effects are less likely to find a statistically significant link between land tenure and investment self reported tenure security has been a poor predictor of investment outcomes second i test for a relationship between land tenure and agricultural investment in nine data sets from west africa while the link between tenure and investment is significant for fallow and tree planting it is less robust for labor use and other inputs such as manure or chemical fertilizer

contradictory land use plans and policies in laos tenure security and the threat of exclusion summary contradicting policies and overlapping property arrangements are common in many countries opening doors for diverse interpretations by different actors this requires better knowledge on how competing interests and actors interact and what determines the practical competition outcomes as demand for land intensifies and international actors get increasingly involved in regulating natural resources land use planning in laos provides a case in point as it aims at strengthening tenure security intensifying agriculture and sparing forest areas while other policies simultaneously promote agricultural development and agri business investment that reconfigure land use and land access through national provincial district village and household interviews we examine how different land and forest related policies interact and whether ongoing land use planning processes and land rights formalization increase tenure security we show how government policies supported by international donors and introduced to strengthen tenure rights for the rural population actually reduce villagers legally permitted agricultural areas even if district level land use regulations do not currently exclude local communities from their land land use plans lay the groundwork for potentially excluding villagers from large land areas we find that plural contradictory regulations and policies combined with existing power inequalities result in a filter mechanism that reduces the practical impact of legal instruments and safeguards aimed at strengthening the least powerful actors rights our results add to other authors arguments that political and legal changes are mediated by power relations cultural norms and economic incentives by highlighting that the duel edged rights sword may actually end up paving the way for greater state control over future benefits derived from community areas classified as forest lands this is especially relevant when preparing redd which we show is likely to weaken rather than strengthen tenure security for rural populations

determinants of biofuel oriented land acquisitions in sub saharan africa abstract the recent surge of investors interest for african land has triggered the debate about the drivers and effects of the so called land grabbing after a review of the relationship between investment in land and biofuel development in sub saharan africa we contribute to the existing literature in four dimensions we use the updated version of land matrix whose potentialities are currently underexploited we concentrate on land deals for cultivating biofuel crops which are emblematic of the food land energy nexus we focus on fdi to the african continent the most targeted region for land grabbing finally we delve deeper into the influence of institutional quality by testing the role of different institutional dimensions we find that abundance of water resources and general business conditions security and regulatory quality facilitate the investment in land for biofuels as for land governance what matters is the strength and security of land tenure rights rather than the type of tenure system

measuring the production efficiency of alternative land tenure contracts in a mixed crop livestock system in ethiopia abstract in this paper we test the hypothesis that land held under varying configurations of property rights will be farmed at different levels of production efficiency production data were collected from 477 plots in a fairly productive mixed farming system in the ethiopian highlands interspatial measures of total factor productivity based on the divisia index were used to measure the relative production efficiency of three informal and less secure land contracts rented share cropped and borrowed relative to lands held under formal contract with the ethiopian government although the informally contracted lands are farmed 10 16 less efficiently the analysis indicates that farmers of such lands actually apply inputs more rather than less intensively i e more inputs per unit of land the gap in total factor productivity thus results from the inferior quality of inputs or lack of skills in applying them rather than a lack of incentive to allocate inputs to mixed crop livestock farming for this reason we find no empirical basis to support the hypothesis that land tenure is a constraint to agricultural productivity

land pressures the evolution of farming systems and development strategies in africa a synthesis abstract evidence assembled in this special issue of food policy shows that rising rural population densities in parts of africa are profoundly affecting farming systems and the region s economies in ways that are underappreciated in current discourse on african development issues this study synthesizes how people markets and governments are responding to rising land pressures in africa drawing on key findings from the various contributions in this special issue the papers herein revisit the issue of boserupian agricultural intensification as an important response to land constraints but they also go further than boserup and her followers to explore broader responses to land constraints including non farm diversification migration and reduced fertility rates agricultural and rural development strategies in the region will need to more fully anticipate the implications of africa s rapidly changing land and demographic situation and the immense challenges that mounting land pressures pose in the context of current evidence of unsustainable agricultural intensification a rapidly rising labor force associated with the region s current demographic conditions and limited nonfarm job creation these challenges are manageable but will require explicit policy actions to address the unique development challenges in densely populated rural areas

can integrated agriculture nutrition programmes change gender norms on land and asset ownership evidence from burkina faso this article uses a mixed methods approach to analyse the impact of an integrated agriculture and nutrition programme in burkina faso on women s and men s assets and norms regarding ownership use and control of assets we use a cluster randomised controlled trial to determine whether productive asset transfers and increased income generating opportunities for women increase women s assets over time qualitative work on gender norms finds that although men still own and control most assets women have greater decision making power and control over home gardens and their produce and attitudes towards women owning property have become more favourable in treatment areas
