Nous étudions le processus de transfert politique selon lequel les idées et valeurs du développement durable, mûries et véhiculées au niveau international, donnent lieu au niveau national à une recomposition des modes publics d’intervention en milieu rural. Au Mali et à Madagascar, les politiques de développement durable recouvrent des expressions différentes. Nous interprétons ces différences par une analyse comparative des stratégies des acteurs intervenant dans le jeu politique. Nous montrons que ces stratégies renvoient à des processus historiques.
Les investissements dans les agrocarburants en Afrique constituent une véritable question de développement. Ils sont pleinement concernés par le débat sur les acquisitions de terres à grande échelle et exposent les populations et les agricultures africaines à plusieurs types de risques. Dans le même temps, ils représentent une opportunité dans des pays où l’accès à l’énergie est sans doute un des principaux facteurs de blocage au développement. Certaines formes d’investissement peuvent être encouragées, à condition qu’elles profitent aux économies locales.
The objective of this paper is to show how Value Chain Analysis for Development (VCA4D) applied sustainable development concept for value chain analysis to establish a manageable set of criteria allowing to provide quantitative information, which is desperately lacking in many situations in developing economies, usable by decision makers and in line with policymakers concerns and strategies (the “international development agenda”).
Developing regions' food system has transformed rapidly in the past several decades. The food system is the dendritic cluster of R&D value chains, and the value chains linking input suppliers to farmers, and farmers upstream to wholesalers and processors midstream, to retailers then consumers downstream. This study analyze the transformation in terms of these value chains' structure and conduct, and the effects of changes in those on its performance in terms of impacts on consumers and farmers, as well as the efficiency of and waste in the overall chain.
The efforts to adapt to climate change in developing countries are in their infancy, and hopefully CSA will be a major contributor to these efforts. But CSA itself is evolving, and there is a growing need to refine and adapt it to the changing realities. This section of the book focus on the implications of the empirical findings for devising effective strategies and policies to support resilience and the implications for agriculture and climate change policy at national, regional and international levels.
Cette document (Note méthodolgique pour l'analyse des chaines de valeur agricoles) combine:
- les réponse aux quatre Questions Structurantes en relation avec l'analyse des chaines de valeurs agricoles.
Question 1: Quelle est la contribution de la chaine de valeur à la croissance économique ?
Question 2: Cette croissance économique est-elle inclusive ?
Question 3: La chaine de valeur est-elle durable du point de vue social ?
Question 4: La chaine de valeur est-elle durable du point de vue environnemental ?
Fish is a key source of income, food, and nutrition in Zambia, although unlike in the past, capture fisheries no longer meet the national demand for fish. Supply shortfalls created an opportunity to develop the aquaculture sector in Zambia, which is now one of the largest producers of farmed fish (Tilapia spp.) on the continent. In its present form, the aquaculture sector exhibits a dichotomy.
The topics addressed in this book are of vital importance to the survival of humankind. Agricultural biodiversity, encompassing genetic diversity as well as human knowledge, is the base upon which agricultural production has been built, and protecting this resource is critical to ensuring the capacity of current and future generations to adapt to unforeseen challenges.
This paper shows that the current generation of transgenic crop varieties has significant potential to improve economic welfare in low-income countries. These varieties might increase crop yields in low-income countries in cases when pesticides have not been used. They will reduce negative health effects of chemicals when they replace them. With low transaction costs, appropriate infrastructure, and access to intellectual property, multiple varieties of transgenics will be introduced.
For millennia, humans have modified plant genes in order to develop crops best suited for food, fiber, feed, and energy production. Conventional plant breeding remains inherently random and slow, constrained by the availability of desirable traits in closely related plant species. In contrast, agricultural biotechnology employs the modern tools of genetic engineering to reduce uncertainty and breeding time and to transfer traits from more distantly related plants.
