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
Este documento presenta los aspectos centrales del Programa Territorios Productivos. Este es un programa para potenciar la productividad, la producción y los ingresos de los hogares en condición de pobreza que son beneficiarios de PROSPERA que habitan en municipios y localidades en que los pequeños productores campesinos tienen un peso social y económico preponderante, priorizando los municipios originalmente seleccionados por la Cruzada Nacional contra el Hambre
This chapter analyses the functioning of the Brazilian agricultural innovation system. It discusses the role of the different actors and describes governance mechanisms to define priorities and evaluate performance. It analyses trends in agricultural R&D expenditure and sources of funding, the role of intellectual property protection in fostering knowledge markets, and outlines mechanisms used to facilitate knowledge transfers, including collaboration at the national level and the adoption of innovation at the farm or firm level.
African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by: advancing scientific and technological research; investing in infrastructure; fostering higher technical training; and creating regional markets.
Increasing of agriculture products is of importance so that research and development in this branch considers as one of the most important infrastructure which develops production growth. Agriculture provides new and improved findings regarding inputs and production methods hence R&D efficiency increases and leads to potential creation in increasing of agriculture products and reduces pressure on natural resources.
According to the literature on regime transition, niches are sources of innovation that may lead to the transformation of the dominant regime, if processes at other level of the system – the landscape and the mainstream regime - are supportive. A focus on actors involved in the transition process and the analysis of their specific role in knowledge networks can help assessing the robustness of a specific niche and its growth potential. Knowledge systems, and in particular the dynamics of local and expert knowledge, have in fact a key role in innovation models.
Au sud-est de la commune de Djougou, les eaux de surface à usage pastoral se raréfient depuis les années 1990. Pour en comprendre l’ampleur et les raisons, nous avons développé un outil permettant une analyse socio-spatiale et socio-environnementale, à l’échelle du finage de deux villages, des dynamiques des ressources, de leurs usages et des stratégies d’accès développées par les populations : un SIG « à dires d’acteurs » associant sur le même support une cartographie classique (réseau hydrographique, forêts, voies de communication, villages, etc.) et l’expertise des populations locales.
