Natural resource management practices, such as the System of Rice Intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of system technologies for farmers are often debated. Impacts seem to be context-specific, which is especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research.
Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a recent survey of smallholder maize farmers in two zones of Tanzania. Hybrid adoption rates are 48% and 13% in the North and East, respectively. Average net yield gains of hybrids are 50-60%, and there are also significant profit effects.
National governments, especially in sub-Saharan Africa, have limited budgets and are forced to make difficult funding decisions regarding the provision of social services and the support of agricultural programs. These provisions can play a critical role in rural incomes and agricultural production but due to data constraints, the effects of different types of social services on agricultural productivity in this region have not been analyzed in detail.
This paper attempts to identify the major factors associated with some of the failures and successes of integrated watershed management policies and projects with a particular emphasis on the uplands of mainland Southeast Asia. It argues that many policy measures have been misguided by failing to acknowledge the multi- dimensional facets of sustainable watershed management and putting too much emphasis on command-and-control approaches to resource management and one- size-fits-all conservation models.
Ever since the Asilomar Conference on ‘Recombinant DNA' in February 1975, regulatory policies relating to recombinant DNA technology have focused on the idea that this technology implies threats to human health and the environment [1].
Extension and advisory services (EAS) perform an important role in agricultural development and help reduce hunger and poverty. Development efforts are increasingly complicated because of challenges such as natural resource depletion and climate change. Agricultural development frameworks have moved from a linear to a more complex systems perspective. Many scholars today use the agricultural innovation systems (AIS) framework as a conceptual model.

Le Programme 2012-2013 de l’Initiative 3N vise à :
- Accroître et diversifier les productions agro-sylvo-pastorales et halieutiques pour assurer la sécurité alimentaire et nutritionnelle des populations nigériennes;
- Augmenter les revenus des producteurs et des acteurs des filières agricoles par l’amélioration de la conservation, la transformation et la commercialisation des produits agro-alimentaires ;
- Améliorer les capacités nationales de prévention et de gestion des crises et catastrophes et la résilience des populations vulnérables.
Ce manuel est destiné aux formateurs des organisations paysannes (OP) et à leurs membres en Afrique sub-saharienne. Le but étant de fournir une formation sur les techniques et opérations après-récolte afin d’améliorer la qualité des grains et ainsi de permettre l’augmentation des revenus et l’amélioration de la sécurité alimentaire des agriculteurs participants au programme. Dans le passé, les formations sur les opérations après-récolte n’ont pas été normalisées entre les différents pays membres du programme P4P.
Cette étude a été menée dans le cadre du projet PAEPARD ou Plateforme pour un partenariat Afrique-Europe dans le domaine de la recherche agricole pour le développement, projet financé à 80% par la Commission européenne avec pour objectif de consolider la collaboration entre l’Afrique et l’Europe dans le domaine de la Recherche Agricole pour le Développement.
