Full textThe comparaison between the agricultural cooperatives ot Togo and Congo brings out resemblances and differences. Are these differences only a reflection of contradictory, geographical, economical, historical, political and ideological situations ? Do their cooperatives allow members and farmers in general, to reach a higher level of development ? What role do state, traders, consumers and foreigner experts play as regards cooperatives ? In conclusion, are cooperatives an adequate means of modernization for rural develoment ? The internal and external factors that enable cooperatives to run are quite easy to identity. However, taking into account the anthropological backround and the political implications, they are (much) more difficult to set up

Full textFamily farming undeniably appears as a pillar of national food security. It represents nearly 80% of farms in sub-Saharan Africa and employs 75% of assets. In the groundnut basin, family farms generally have an average size between one and five hectares, but they face the various challenges of food security, social equity and environmental sustainability. In addition, they face structural constraints of organizational and economic order in a context of climate uncertainty. Thus, this thesis seeks to understand the strategies used by family farms toward the various risks and alternative proposals from other actors in the sector's development. It is, at once, to identify the main constraints arising farms and strategies they cause to propose additional or alternative strategies in the analysis of the risk management framework. For such an aim, we arrested the concepts of family farm, risk, vulnerability and agricultural insurance to reflect the dimensions of this subject for research. This theoretical and conceptual framework was operationalized on the field within farms, giving a voice to farm managers. Several investigations have been conducted and focused on socio-demographic, structural and technical indicators, principal risks and constraints at the farm level, the perception of agricultural insurance. It appears from this study that the main risks identified are agriculture and climate. Family farms consider access to inputs (fertilizer and seed) and farm equipment as a structural constraint in the rainfall deficit. Also, it appears a significant vulnerability in its three components at farm level Basin. This reflection shows the limits of the strategies developed by the farms to improve their resilience in the context of rained groundnut basin; and justifies the need to go to new complementary strategies. One of the tracks that we have explored is the agricultural index insurance. Its coupling to credit, as collateral to financial institutions and to provide working capital is positively appreciated by the subscribers who, up to 95%, are willing to extend the use of insurance policies

Full textThe fundamental objective of this research is to explore the impact of rice price policy on the growth of rice production and on income distribution in six African countries. In a first part, we outline the rice sector performance of each country since twenty years; we then analyze the rice price policy followed by the governments; the international price of rice has been used to judge national policies. The second part has two main purposes: the first one is to point out the extent in which rice price policy lead to an increase in rice production. The empirical analysis reveals that rice supply is responsive to real and relative price of rice changes. The second main center of interest concern the effect of rice price policy on income distribution: income transfers between farmers, consumers and the state are highlighted they are evaluated in reference to a freely market determination of rice prices

Full textIn our thesis, we assume that African Sub-saharan countries' food security status can be enhanced through a better management of agricultural commodities prices instability, which constitutes the basic food basket of local populations. To this aim, we initially review the dynamics of agricultural markets and the role played by “prices” in this mechanism as well as the existing linkages between unstable price trends and the notion of food insecurity. Focus is then directed to the relationship between “food insecurity” and the regulation of the agricultural sector, in particular within international trade theory frameworks.Finally, we proceed to the assessment of “food insecurity” through the empirical analysis of the instabilities affecting food prices of the region, and also that of price transmission and linkages within and between countries. We then highlight prices instabilities at individual (country) level, as well as the linkage of these prices (therefore of their unstable components) between the various constituents of the basic food basket of a given country, or that of neighboring countries.All along our thesis, food insecurity resilience measures for these countries are suggested. These measures are believed to potentially serve as initial steps in the establishment of national and regional agricultural policies aiming at attaining/safeguarding food security in African sub-Saharan countries

Full textIn microfinance, the success of the major networks is closed to constant failures of rural cooperative organizations which are struggling to remain after their institutionalisation and their autonomy. The failure of rural mutual or cooperative organizations is related to the problem of governance. Considering the types of governance to reduce transaction costs and conflicts caused by the relations between agencies do not reflect exactly the dynamic aspect of governance in microfinance. This limit is raised by the heterodox theory that combines the genesis of new executives from the interaction of stakeholders and trade-offs which come out of that in order to stabilize organizations. We chose an approach by stakeholders and to justify this choice, we have used the model of Gérard Charreaux analysis, the Daniel Côté cooperative balance model and the Christian Cadiou theoretical model of the stakeholders. On the field, we have mobilized analysis tools of governance of the cherry in the case of the Niayes Remec. So, we bear in mind that cooperatives and rural mutual are the result of the melting between resources and superposition of associative and entrepreneurial practices. They are more able to endure the withdrawal of the external support when they benefit from that after their setting up by members. External participation strengthens resources and threatens the democratic balance, and it triggers a process of repatriation of authorities from leaders to the wage-earning staff. When the co-operative organizations are disconnected from their base (members), the social mechanisms do not play their auto-enforcement role efficiently

Full textIn a context of major questioning about polluting industrial processes and mobilising non-renewable resources, structural modifications in order to set up sustainable production methods and to establish the economical growth in a long-term base, are namely necessary for african countries in their development stratégies.In this way, spirulina valorisation, a renewable resource, for multiple use and with outstanding properties, belongs in this logical.Besides its therapeutic values and nutritional qualities, spirulina is not only safe for environment, but also it presents interest due to photosynthesis.In terms of socio-economics, spirulina could bring significant response to underdevelopment problems, and namely malnutrition and poverty. Indeed, its valorisation permit to generate regular incomes to the persons who work in and also, permit financial empowerment of vulnerable population groups.Nowadays, spirulina valorisation spread accross Africa but continuity and succes of spirulina projects depend on various challenges to be met.Therefore, the aim of this work is to demonstrate in what way, how and under which conditions, sustainable development strategies based on spirulina valorisation can be a vector of development for Subsahara Africa countries

Full textIncreasing agricultural productivity and fostering agricultural development are necessary for agriculture to play an effective role in food security and poverty reduction in Sub-Saharan Africa. The literature has identified several barriers to agricultural development, including environmental constraints, institutional constraints, as well as resource constraints. However, how to promote agricultural development in Sub-Saharan Africa remains a challenging issue. This dissertation addresses three important issues relating to agricultural development in Sub-Saharan Africa, and particularly in Burkina Faso. The dissertation considers how institutions and policies can have an impact on the constraints faced by individual farmers and households, and how to foster the emergence of institutions that will work for agricultural development. The first chapter of this dissertation investigates the role of norms and institutions in the formation of farmer organizations, and women’s participation in farmer organizations. The findings indicate that female farmers are less likely to participate in farmer organizations. The results suggest that the relatively low level of female participation in farmer organizations is explained by women’s lack of resources including information as well as a lack of incentives to participate. The second chapter studies the emergence conditions of land markets in the Hauts-Bassins region Burkina’s cotton zone. The chapter’s findings highlight the equalizing role of land markets in this region. Land markets enable migrants to gain access to land in this region. Last, the third chapter of this dissertation seeks to understand the relative, apparent low use of chemical fertilizers by farmers. The low uptake of chemical fertilizers might have been driven by factors other than profitability, including a lack of access to fertilizers and credit. Building on the theoretical literature in economics as well as the literature in other social sciences, and on various datasets, this dissertation contributes to enhancing the overall understanding of the issues faced by farmers in Sub-Saharan African countries and points towards further research in the economics of agricultural development as well as in the general economic literature

Full textEnvironmental and climate issues constitute a predominant and much up to date topic in international discussions. It is broadly recognized that developing countries are the most vulnerable when it comes to climate issues, albeit, they are the least responsible. Finding ways for households’ of these countries to cope with the harmful effects of climate goes through the necessity to identify mechanisms that can help, such as migration and remittances. The latter have been found in the scientific literature to be a hedge against several shocks such as natural disasters, conflicts, and economic shocks.This research thesis explores the theme of remittances, and climate variability in developing countries, by focusing on a sub-Saharan African country, Burkina Faso. Compared to its neighbouring countries, Burkina Faso has not been subject to much research in the migration and remittances. The country however has a vast migration history that is worth studying. Climate issues are also rampant, and very important, as the country is practising subsistence agriculture. The findings of this dissertation show that remittances have a positive impact on households’ ability to cope with the negative effects of climate issues. Yet these important sources of inflows for developing countries might have some limitations. The first chapter assesses the impact of remittances and climate variability on the food security of households in Burkina Faso. We build a food security index using principal component analysis that encompasses the accessibility and utilization dimensions of the concept. We also compute an inter-annual rainfall index and the latter is found to have a negative impact on food security. After controlling for potential endogeneity issues using distance variables and migrant characteristics as instruments, remittances are found to enhance food security. Results are robust to alternative measures of food security and alternative calculations of rainfall variability. In Chapter two, we assess the impact of remittances and natural disasters on poverty in Burkina Faso. To do so, we construct a poverty index using household’s housing characteristics and Multiple Correspondence Analysis method. Propensity score matching method is used as an empirical strategy, and results show that remittances have a negative impact on poverty. Another important result is that remittances have a higher impact on the resilience of households, when they have experienced disasters in the past. Therefore, when it comes to natural disasters, these inflows act as an important tool for populations to be more resilient. Lastly in chapter 3, we assess the role of remittances and drought on diversification strategies of farm-households. This chapter uses the same database as chapter two, and also takes advantage of the climate database of the Climatic Research Unit (CRU) of University of Anglia . Results show that remittances by themselves are not sufficient to push households towards costly diversification strategies, and they need to be conditional to households’ wealth status to be effective. Climate conditions as well as soil properties have not surprisingly been found to significantly push households towards diversifying their income.This research sheds light on the undeniable importance of remittances in helping households to cope with harmful effects of climate, but also on its limitations. International and national policies that will contribute in a more efficient and less costly conveying of these inflows are to encourage. However in order for remittances to be efficient, reducing inequalities and poverty within populations is a necessity. Otherwise, they can contribute to dig further poverty gaps and extensively the vulnerably levels inside populations. Therefore, remittances should be seen as complementary to other sources of income, rather than substitute
