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”).
This paper provides a retrospective look at a systems-oriented research program, on the increasing occurrence of parasitic weeds in rainfed rice in sub-Saharan Africa, to qualitatively assess merits and identify challenges of such approach. Was gained a broad contextual overview of the problem and different stakeholders' roles, which enabled identification of entry points for innovations in parasitic weed management
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.
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.
This book summarizes the achievements as well as some of the challenges faced while implementing integrated systems research to support the sustainable development of smallholder farming in the uplands of the Mekong region.
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 objective of this paper is to explore the extent to which systems approaches to innovation are reflected in the crop protection literature and how such approaches are used. A systematic literature review is conducted to study the relation between crop protection and systems approaches to innovation in 107 publications. The analysis of the crop protection literature demonstrates that only a small fraction is systems-oriented as compared to the bulk of publications with a technology-oriented approach.
Xanthomonas Wilt of Banana (BXW) is a complex problem in the African Great Lakes Region that is affecting the livelihoods of millions of smallholder farmers. Since the first disease reports from Uganda and the Democratic Republic of Congo in 2001, BXW has been studied widely. The majority of these studies focus on the technological or biophysical dimensions, while aspects and influence of socio-cultural, economic and institutional dimensions only recently started to gain attention.
