description: We explore some implications of our previous proposal, motivated in part by the Generalised Uncertainty Principle (GUP) and the possibility that black holes have quantum mechanical hair that the ADM mass of a system has the form $M + βM_\mathrm{Pl}^2/(2M)$, where $M$ is the bare mass, $M_\mathrm{Pl}$ is the Planck mass and $β$ is a positive constant. This also suggests some connection between black holes and elementary particles and supports the suggestion that gravity is self-complete. We extend our model to charged and rotating black holes, since this is clearly relevant to elementary particles. The standard Reissner-Nordström and Kerr solutions include zero-temperature states, representing the smallest possible black holes, and already exhibit features of the GUP-modified Schwarzschild solution. However, interesting new features arise if the charged and rotating solutions are themselves GUP-modified. In particular, there is an interesting transition below some value of $β$ from the GUP solutions (spanning both super-Planckian and sub-Planckian regimes) to separated super-Planckian and sub-Planckian solutions. Equivalently, for a given value of $β$, there is a critical value of the charge and spin above which the solutions bifurcate into sub-Planckian and super-Planckian phases, separated by a mass gap in which no black holes can form.

description: Durch zahlreiche Gesetzestexte oder Richtlinien sowohl auf europäischer als auch nationaler Ebene gelang es in den letzten Jahren den Anbau von Energiebiomasse zu forcieren. Aufgrund aktueller Entwicklungen auf den Agrar- und Energiemärkten kommt es nun verstärkt zur Konkurrenz zwischen der Nahrungsmittel- und der Energieproduktion um den knappen Faktor Boden. Ein weiterer Ausbau der Bioenergieproduktion auf Basis von Biomasse führt zu einer Verdrängung der auf Lebensmittelproduktion ausgerichteten Landwirtschaft. Die Folgen für die regionale Wirtschaft können deshalb nicht nur als positiv bewertet werden. Sowohl der Arbeitkraftbedarf als auch die Wertschöpfung kann sich in der Region in Folge einer Verdrängung arbeitsintensiver Veredelungsketten verringern.

description: In this letter we investigate a class of Hamiltonians which, in addition to the usual center-of-mass (CM) momentum conservation, also have center-of-mass position conservation. We find that regardless of the particle statistics, the energy spectrum is at least q-fold degenerate when the filling factor is $p/q$, where $p$ and $q$ are coprime integers. Interestingly the simplest Hamiltonian respecting this type of symmetry encapsulates two prominent examples of novel states of matter, namely the fractional quantum Hall liquid and the quantum dimer liquid. We discuss the relevance of this class of Hamiltonian to the search for featureless Mott insulators.

description: The expansion of renewable energy sources is an EU strategy to reduce the dependency on fossil fuels and to curb carbon dioxide emission. According to studies estimating technical potentials, significant land resources can be mobilised for the production of energy crops. We estimate the costs of a policy aiming at a stimulation of biomass and bioenergy production in Austria using a model that integrates the production of food, feed, agricultural and forest biomass as well as bioenergy products. The results show that an expansion of domestic biomass and bioenergy production is costly and it diminishes the production of food and feed.

description: The Cosmic Microwave Background (CMB) has been measured over a wide range of multipoles. Experiments with arc-minute resolution like the Atacama Cosmology Telescope (ACT) have contributed to the measurement of primary and secondary anisotropies, leading to remarkable scientific discoveries. Such findings require careful data selection in order to remove poorly-behaved detectors and unwanted contaminants. The current data classification methodology used by ACT relies on several statistical parameters that are assessed and fine-tuned by an expert. This method is highly time-consuming and band or season-specific, which makes it less scalable and efficient for future CMB experiments. In this work, we propose a supervised machine learning model to classify detectors of CMB experiments. The model corresponds to a deep convolutional neural network. We tested our method on real ACT data, using the 2008 season, 148 GHz, as training set with labels provided by the ACT data selection software. The model learns to classify time-streams starting directly from the raw data. For the season and frequency considered during the training, we find that our classifier reaches a precision of 99.8%. For 220 and 280 GHz data, season 2008, we obtained 99.4% and 97.5% of precision, respectively. Finally, we performed a cross-season test over 148 GHz data from 2009 and 2010 for which our model reaches a precision of 99.8% and 99.5%, respectively. Our model is about 10x faster than the current pipeline, making it potentially suitable for real-time implementations.

description: In Deutschland genießen die Energie- und Klimapolitik und mit ihr die erneuerbaren Energien bereits seit längerer Zeit eine erhöhte Aufmerksamkeit. Von politischer Seite wurden weitreichende Förderungsmaßnahmen und Anreize zur Investition in erneuerbare Energien geschaffen. Aufgrund der guten produktionstechnischen Voraussetzungen der Landwirtschaft zur Erzeugung von Bioenergie hat dies in den vergangenen Jahren zu einem regelrechten Biogas-Boom auf landwirtschaftlichen Betrieben geführt. Für diese Betriebe bedeutet die Investition in eine Biogasanlage gleichzeitig eine Diversifikation des Tätigkeitsspektrums. Der vorliegende Beitrag untersucht, welche Faktoren (betriebsstrukturelle Merkmale und Einstellungen der Betriebsleiter) diese Diversifikation und somit die Adoption der Innovation „Biogasanlage“ begünstigt haben. Datengrundlage bilden die Ergebnisse einer Befragung von 1.055 Landwirten in Niedersachsen, von denen 97 Betriebe in eine Biogasanlage investiert haben.

A Generalized Boltzmann Kinetic Theory for Strongly Magnetized Plasmas with Application to Friction

Year: 2020
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Coulomb collisions in plasmas are typically modeled using the Boltzmann collision operator, or its variants, which apply to weakly magnetized plasmas in which the typical gyroradius of particles significantly exceeds the Debye length. Conversely, O'Neil has developed a kinetic theory to treat plasmas that are so strongly magnetized that the typical gyroradius of particles is much smaller than the distance of closest approach in a binary collision. Here, we develop a generalized collision operator that applies across the full range of magnetization strength. To demonstrate novel physics associated with strong magnetization, it is used to compute the friction force on a massive test charge. In addition to the traditional stopping power component, this is found to exhibit a transverse component that is perpendicular to both the velocity and Lorentz force vectors in the strongly magnetized regime, as was predicted recently using linear response theory. Good agreement is found between the collision theory and linear response theory in the regime in which both apply, but the new collision theory also applies to stronger magnetization strength regimes than the linear response theory is expected to apply in.

description: Im Zuge der Reform der EU-Agrarpolitik werden seit dem Midterm-Review zunehmend weniger politische Instrumente zur Stützung des europäischen Milchmarkts eingesetzt. Dadurch und durch die wahrscheinlich im Zuge der WTO-Verhandlungen erfolgende Lockerung des EU-Außenschutzes werden Milcherzeuger wesentlich stärker als bisher den Kräften des Marktes und den damit verbundenen Risiken ausgesetzt. Vor diesem Hintergrund war das Ziel der vorliegenden Studie, die Risikowahrnehmung der Landwirte aus einer verhaltenswissenschaftlichen Perspektive zu untersuchen. Datengrundlage bildet eine Befragung von 236 Milcherzeugern zum Risikomanagement auf ihren Betrieben. Dabei wurden Politik-, Markt- und Preis- sowie Produktionsrisiken hinsichtlich ihrer Eintrittswahrscheinlichkeit und Schadenauswirkung bewertet. Risiken auf den Faktormärkten stehen dabei im Vordergrund, gefolgt von Politik- und Produktionsrisiken. Weiterhin wurden die empirischen Ergebnisse vor dem Hintergrund neuerer Forschungsarbeiten zur Risikowahrnehmung und zu kognitiven Entscheidungsheuristiken interpretiert. Insgesamt konnten dabei verschiedene Erklärungsansätze für die Wahrnehmung von Risiken aufgezeigt und mögliche Einflussfaktoren von Wahrnehmungsverzerrungen identifiziert werden.

description: We show that microscopic entropy formula based on Virasoro algebra follows from properties of stationary Killing horizons for Lagrangians with arbitrary dependence on Riemann tensor. The properties used are consequence of regularity of invariants of Riemann tensor on the horizon. Eventual generalisation of these results to Lagrangians with derivatives of Riemann tensor, as suggested by an example treated in the paper, relies on assuming regularity of invariants involving derivatives of Riemann tensor. This assumption however leads also to new interesting restrictions on metric functions near horizon.

description: Following the two rounds of land reform in Ukraine since independence, household plot farmers emerged as the major suppliers of agricultural goods. But they form a very heterogeneous group. Not all of them are equally successful and integrated to markets. In general, a varying degree of access and adoption of production factors is identified as being of influence. In this paper, we argue that social capital is an additional factor contributing to higher agricultural incomes. We tested our hypothesis using primary evidence from a survey in Ukraine among 255 household plot farmers. Based on 23 social capital indicators we deduced four separate index variables linking the social capital dimension of form, i.e. structural and cognitive, with the social capital dimension of relationship, i.e. bonding and bridging. By adopting multiple regression analysis we can show that social capital of its bridging structural type is indeed a significant factor determining the level of agricultural income. However, the findings also underline the multidimensional side of social capital. Both bonding and cognitive social capital have no impact on agricultural income. We conclude that social capital can be identified as a significant production factor but its underlying indicators do not seem to point to the same direction and have to be analysed in their specific contexts.

Linear time algorithm for parsing RNA secondary structure
Creators: name: Rastegari, Baharak
Publisher: name: University of British Columbia
Year: 2009

description: RNA secondary structure prediction is an important problem in computational molecular biology. Experiments show that existing polynomial time prediction algorithms have limited success in predicting correctly the base pairs, i.e. secondary structure, in known biological RNA structures. One limitation of many current algorithms is that they can predict only restricted classes of structures, excluding many so-called pseudoknotted secondary structures. The type of the pseudoknotted structures that occur in biological structures, as well as the type of structures handled by current algorithms, have been poorly understood, making it difficult to assess the generality of current algorithms. In this thesis we present a comprehensive and precise classification of structural elements and loops in a secondary structure, along with a linear time algorithm for parsing secondary structures into their structural elements. The parsing algorithm, along with the classification scheme for the loops in a pseudoknotted secondary structure, can be used in analysing existing prediction algorithms to determine which known biological RNA structures can not be predicted by the algorithms. This analysis can help us to design new and more powerful prediction algorithms. Furthermore, we present two applications of our work: (i) linear time free energy calculation algorithm, and (ii) linear time test for Akutsu's[2] algorithm class. We present a linear time algorithm for calculating the free energy of a given secondary structure. This algorithm can be useful especially in heuristic prediction algorithms, as they commonly use a procedure to calculate the free energy for a given sequence and structures. We also present a linear time algorithm to test whether the prediction algorithm introduced by Akutsu[2] can handle a given structure. The result of our analysis on algorithm of Akutsu on some sets of biological structures shows that although it is proved theoretically that the class of structures handled by Akutsu's algorithm is more general than that handled by the algorithm of Dirks and Pierce [7], they can both handle the same class of given biological structures.

Adiabatic-antiadiabatic crossover in a spin-Peierls chain

description: We consider an XXZ spin-1/2 chain coupled to optical phonons with non-zero frequency $ω_0$. In the adiabatic limit (small $ω_0$), the chain is expected to spontaneously dimerize and open a spin gap, while the phonons become static. In the antiadiabatic limit (large $ω_0$), phonons are expected to give rise to frustration, so that dimerization and formation of spin-gap are obtained only when the spin-phonon interaction is large enough. We study this crossover using bosonization technique. The effective action is solved both by the Self Consistent Harmonic Approximation (SCHA)and by Renormalization Group (RG) approach starting from a bosonized description. The SCHA allows to analyze the lowfrequency regime and determine the coupling constant associated with the spin-Peierls transition. However, it fails to describe the SU(2) invariant limit. This limit is tackled by the RG. Three regimes are found. For $ω_0\llΔ_s$, where $Δ_s$ is the gap in the static limit $ω_0\to 0$, the system is in the adiabatic regime, and the gap remains of order $Δ_s$. For $ω_0>Δ_s$, the system enters the antiadiabatic regime, and the gap decreases rapidly as $ω_0$ increases. Finally, for $ω_0>ω_{BKT}$, where $ω_{BKT}$ is an increasing function of the spin phonon coupling, the spin gap vanishes via a Berezinskii-Kosterlitz-Thouless transition. Our results are discussed in relation with numerical and experimental studies of spin-Peierls systems.

description: We generalize the numerical renormalization group scheme to study the phonon-mediated retarded interactions in the high Tc cuprates. We find that three sets of phonon-mediated retarded quasiparticle scatterings grow under RG flow. These scatterings share the following common features: 1) the initial and final quasiparticle momenta are in the antinodal regions, and 2) the scattering amplitudes have a $x^2-y^2$ symmetry. All three sets of retarded interaction are driven to strong coupling by the magnetic fluctuations around $(π,π)$. After growing strong, these retarded interaction will trigger density wave orders with d-wave symmetry. However, due to the d-wave form factor they will leave the nodal quasiparticle unaffected. We conclude that the main effect of electron-phonon coupling in the cuprates is to promote these density wave orders.

description: Africa is a region of female farming compared with other regions of the world where women have the responsibility for food production, processing, marking, cooking, child care and other home related activities. It is argued that women account for 70-80 percent of household food production in sub-Sahara Africa. However, case studies in Nigerian and in most Africa countries tend to point to the fact that women who have been described as the hidden productive force in the countryside have not fully benefited from food production development planning strategies, despite their increased involvement in agricultural production. The food production development programme has often focused in the designing of effective packages for generating surpluses in agriculture without particular focus on women. The basic needs approach which emphasis the expansion of people’s capabilities therefore points to the importance of re-examining the strategies for promoting participation in agricultural production with specific focus on women. Food development planning and execution strategies need to be re-oriented and re-designed to ensure that development packages reach women farmers as well as stimulate them to participate more actively to increase output though technology and other incentives. This paper therefore focuses on the importance of women’s participation in Nigerian agricultural production and its implications for national development. The neglect of women’s roles in agriculture and factors that have adversely affected rural women’s agricultural production is also reviewed. Finally, the paper proposes some socio-economic, socio-cultural and institutional structures that must be re-examined and redesigned to facilitate the increase women participation in Nigeria main streaming agriculture.

description: We investigate, analytically near the dimension $d_{uc}=4$ and numerically in $d=3$, the non equilibrium relaxational dynamics of the randomly diluted Ising model at criticality. Using the Exact Renormalization Group Method to one loop, we compute the two times $t,t_w$ correlation function and Fluctuation Dissipation Ratio (FDR) for any Fourier mode of the order parameter, of finite wave vector $q$. In the large time separation limit, the FDR is found to reach a non trivial value $X^{\infty}$ independently of (small) $q$ and coincide with the FDR associated to the the {\it total} magnetization obtained previously. Explicit calculations in real space show that the FDR associated to the {\it local} magnetization converges, in the asymptotic limit, to this same value $X^{\infty}$. Through a Monte Carlo simulation, we compute the autocorrelation function in three dimensions, for different values of the dilution fraction $p$ at $T_c(p)$. Taking properly into account the corrections to scaling, we find, according to the Renormalization Group predictions, that the autocorrelation exponent $λ_c$ is independent on $p$. The analysis is complemented by a study of the non equilibrium critical dynamics following a quench from a completely ordered state.

description: Agriculture, unlike industrial activity which has always resulted in pollution, has been environmentally benign for most of its history until after the Second World War when the system disintegrated. Then, crop residues were incorporated into the soil or fed to livestock, the manure returned to the land in amounts that could be absolved and utilized. Mechanized farming, however, is reliant on synthetic fertilizers and pesticides. Hence, crop residues and livestock excreta, which were once recycled have become wastes and their disposal a continuing problem for the farmer. With the present national policy on agriculture, there is the need for private sector participation especially in the area of environmental health and safety for economic and environmental sustainability.

Using the well-known Newton-Raphson iterator we numerically locate the position of the points of equilibrium, while we also obtain their linear stability. Furthermore, we demonstrate how the two variable parameters, entering the generalized Hénon-Heiles potential, affect the convergence dynamics of the system as well as the fractal degree of the basin diagrams. The fractal degree is derived by computing the (boundary) basin entropy as well as the uncertainty dimension.

description: Increasing attention is being accorded the potential role of women farmers in Plateau State due to their significance in sustainable agricultural development. However, production impediments have often diminished the hope to fully utilise such potentials for the benefit of humanity. A study was conducted in Kanam and Wase L.G.As to examine production characteristics of women farmers in the study areas. 200 women farmers were selected from 8 wards by simple random sampling technique. However, 198 responses were available for analysis Descriptive statistics – frequency and corresponding percentages is used for analysis. The result of the study revealed that greater number of the women range between ages of 30-39 years. (52.%) Married women were majority (72.22%), primary school leavers were majority (40.40%) majority of them operate on their husband’s farm (68.18%) major source of finance is personal savings (83.33%) major farm enterprise are cattle, sheep, goat, crops (100%). Major source of labour is family labour (50.51%) common size of farm holding is less than 2 hectares (65.66%) constraints identified includes: Non Accessibility to land ownership (98.48%)Iinadequate access to reliable source of loanable funds (89.%) Non availability of village level technology (100%). The conclusion is that their production level is characterized by small holder agriculture with associated impediments. In view of the importance attached to role of women in agriculture, significant effort is required through effective extension services to alleviate the burden of the women.

description: In reaction to worrisome performance of agricultural sector in Nigeria, the Federal Government has embarked on various programs and projects aimed at returning the sector to its enviable position. The government efforts have not yielded sufficient desired results, as the country still witnessed high cost of food, general cost of living and perpetual poverty. This paper suggested a redirection of the government efforts to privatization of agricultural enterprises, projects and programs, since it has been shown to have capacity to increase the efficiencies of the concerned enterprises. This study relied on secondary data from Malawi and primary data from private cocoa farmers in Oyo state in Nigeria. The empirical evidence from Malawi shows that technical efficiency of agro-allied industries increased from 65% before privatization to 72% after privatization. The determinants of technical efficiency of the agro-allied industries in Malawi are state ownership, monopoly, capital intensity, Multinational Corporation, and structural adjustment program. While state ownership and monopoly reduce the efficiency, the other three determinants increase it. This indicates that agro allied industries can be more efficient under private control than under the State (Government). The result of analysis of the primary data suggests that farmers that pay for their land are more technically efficient (63%) than those who did not (59%). This allay the fear that increased in cost, that is associated with privatization will not reduce the technical efficiency of the farmers. The paper recommends a gradual privatization of agricultural enterprises, projects and programs in Nigeria. This will not only increase their efficiency but also gender active participation and competition.

description: The study analyzed the performance of cycle traders in the marketing of foodstuffs in Mamu, Ogun State, Nigeria. A survey was carried out in the boundary market over five cycle market days across one hundred and fifty (150) foodstuffs traders. Cycle traders were grouped into fifteen (15) homogenous foodstuffs trading categories. Descriptive analytical tools were then used to analyse the socio-demographic characteristics of foodstuffs marketers in the market. Further, quantitative analytical tools were used to analyse the extent of inequalities in the stock levels and trade volume, market expenditures, and returns to traders. Results revealed that majority of the cycle traders in the sample had low educational attainment, and were married into polygamous families of four to ten children, on the average. Indices of inequality also revealed that there was a relative equality in incomes realized by traders on cycle market days. Notwithstanding the relative equality in market expenditures, stock levels, volume of trade, and market incomes, training programme should be organized for boundary market traders. Such educational programmes should focus on improving the literacy ability, and the accounting and trading skills of cycle marketers in the study area.

description: In Nigeria, agricultural extension services have been dominated by the Agricultural Development Programme (ADPs) since the mid-1970s. However, the experiences of farmers are changing. Traditional extension services linked with production objectives and blanket recommendations can no longer meet farmers’ expectations. Therefore, extension practitioners need to meet this challenge by seeking private sector participation in the funding and delivery of extension services. This paper noted that extension services provided by the private sector, even when it is funded by government, is a positive feature and government can play a strategic role in identifying gaps in the provision of extension services that can be filled through a brokerage role or by contracting service providers. It then concluded that the sustainability of private sector participants in extension service delivery requires a new orientation among staff. This will require some investment in staff training and reorientation.
Search for a Lorentz invariance violation in atmospheric neutrino oscillations using MACRO data

description: The energy spectrum of neutrino-induced upward-going muons in MACRO was analysed in terms of special relativity principles violating effects, keeping standard mass-induced atmospheric neutrino oscillations as the dominant source of nu_mu nu_tau transitions. The data disfavour these exotic possibilities even at a sub-dominant level, and stringent 90% C.L. limits are placed on the Lorentz invariance violation parameters. These limits can also be re-interpreted as upper bounds on the parameters describing violation of the Equivalence Principle.

Food Security and Poverty

description: Poverty in Nigeria is concentrated in rural areas. Low resource or resource-poor farmers characterized by preponderance of small farm units, fragile soils, rain-dependent, minimum inputs and poor yield dominate the agricultural sector. The incidence of poverty is highest among households in which the head is engaged in agriculture as the main source of income. Agricultural growth is therefore important to the eradication of extreme poverty and hunger in Nigeria. Conscious policy efforts by government towards poverty alleviation began during the SAP era. Some companies like Shell and certain State Governments have shown real interest in alleviating poverty through their agricultural programmes and policy statements. Nigeria’s current vision for agricultural development is expressed in the National Economic Empowerment and Development Strategy (NEEDS), the New Agricultural Policy (NAP), and the Rural Sector Development Strategy (RSDS). This paper posits that provision of electricity, potable water, health centres and formal schools will facilitate the sustainability of any impact of poverty alleviation programmes in Nigeria. Encouraging community development projects evolved by the communities themselves will minimize poverty incidence. Increasing the access of the poor to land and other productive resources will reduce poverty and generate employment. Development of infrastructural facilities in the rural areas has the two pronged approach of reducing poverty and developing the rural areas. Encouraging processing through adequate incentives to SMEs will also further empower the private sector.
Understanding stochastic local search algorithms : an empirical analysis of the relationship between search space structure and algorithm behaviour

description: Combinatorial optimisation problems are an important and well-studied class of problems, with applications in most areas of the computing sciences. Because of their prominence, combinatorial optimisation problems and their related decision problems have been the focus of extensive research for several decades. The propositional satisfiability problem (SAT), in particular, has been the focus of a vast amount of research, and a class of algorithms known as stochastic local search (SLS) algorithms has emerged as the state-of-the art on a variety of SAT problem classes. Much of the recent progress in algorithm development has been facilitated by an improved understanding of the properties of SAT instances and of high-performance SAT algorithms. This thesis studies the search space features underlying the behaviour of stochastic local search algorithms for SAT, extending existing results from the literature and providing novel contributions. Search space features such as plateaus and the interconnectivity between plateaus are defined and studied on a variety of SAT instances, and it is empirically demonstrated that features such as these are responsible for the wide range in instance hardness observed in distributions of syntactically identical SAT instances. Furthermore, the novel concept of the performance criticality of variables in SAT instances is introduced, and the connections between search space structure and performance criticality are investigated. Finally, methods for practically exploiting the knowledge gained by this search space analysis are briefly explored, with the goal of improving the state-of-the-art in SAT solving.

description: The study examined the factors influencing farm credit delivery decisions by Cooperative Societies in Edo and Delta States. Primary data were obtained from 809 loan applications selected from 80 Cooperative Societies purposively selected from 16 LGAs with the assistance of the Ministries of Commerce and Industry. Descriptive statistics and the logit model were used to analyse the data. The results showed that all the Cooperative Societies were multipurpose, but with credit delivery as their major function. They had a male to female ration of 4:1 and a high loan approval rate of 95%. Gender, age and educational level were examined as factors influencing loan decisions. The results of the cross-categorical analysis of the 2x2x2x2 model showed that being a male above 40 years old with no formal education had the highest possible likelihood of increasing the probability of loan decision being positive. The combined effect of all the factors however showed high statistical significance with a Chi square (Χ2) value of 29.20 and a likelihood ratio (G2) of 35.01 at 1%. The study therefore concluded that the major factors influencing the loan delivery decision were gender and age as formal education did not seem to enhance the decision.

description: AGOA directs the President of the United States to convene an annual meeting between the U.S. government and representatives of eligible African countries and to prepare an annual report to Congress on U.S. trade and investment policies with sub-Saharan Africa (SSA). Currently, Angola, Gabon, Nigeria and South Africa- accounted for the bulk (84 percent) of U.S. total imports from SSA. Since the passage of AGOA, the business climate has improved for non-agricultural exports and growth in these sectors has made relatively low direct benefits to Africa’s poor. Consequently, expanding AGOA’s application to African agriculture would have a significant impact on reducing hunger and poverty and therefore, on improving overall conditions in SSA. As a result of inadequate technology availability to increase agricultural output in order to take advantage of AGOA after meeting domestic needs, it is necessary to encourage a synergic approach to farming such as the African integrated farming system. Secondly, the paper posits that integrated agriculture will be cost effective in reducing the high cost structure of agricultural production in the SSA. AGOA should encourage and support African countries in the establishment and enforcement of effective laws, rules and regulations governing international trade and marketing. In conclusion the paper urged the U.S. government to adopt a comprehensive African policy, including a strengthened AGOA, increased development assistance, increased emphasis on agriculture and rural development, and a vigorous response to famine and civil conflicts.
