Les conséquences sur les territoires des changements climatiques d’origine anthropique sont variables dans leurs expressions comme dans leurs effets, et les territoires sont inégaux face à ces variations climatiques en termes d’exposition aux effets (fonction de facteurs physiques, sociaux, économiques, culturels, politiques, etc.) comme en termes de capacité de réponse (capacité d’appréhension, d’anticipation, de réparation, etc.).
L’enjeu environnemental pour les territoires croît de façon exponentielle depuis une décennie. Les décideurs politiques s’emparent de cette mouvance et favorisent des actions qui entrent dans le projet dit durable. La Région Île-de-France choisit en partie de baser son développement territorial sur l’idéologie de l’« urban greening ». Elle met en œuvre des actions pour devenir la première Écorégion d’Europe d’ici une demi-douzaine d’années et, pour ce, favorise les mesures agro-environnementales. Un des piliers de ce développement est l’agriculture biologique.
This Economic and Sector Work paper, “Enhancing Agricultural Innovation: How to Go Beyond the Strengthening of Research Systems,” was initiated as a result of the international workshop, “Development of Research Systems to Support the Changing Agricultural Sector,” organized by the Agriculture and Rural Development Department of the World Bank in June 2004 in Washington, DC.
The purpose of this paper is to map some elements that can contribute to an IFAD strategy to stimulate and support pro-poor innovations. It is an initial or exploratory document that hopefully will add to an ongoing and necessary debate, and is not intended as a final position paper. The document is organized as follows.
The purpose of this article is to investigate effective reformism: strategies that innovation networks deploy to create changes in their environment in order to establish a more conducive context for the realization and durable embedding of their innovation projects. Using a case study approach, effective reformism efforts are analyzed in a technological innovation trajectory related to the implementation of a new poultry husbandry system and an organizational innovation trajectory concerning new ways of co-operation among individual farms to establish economies of scale.
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.
This report provides a synthesis of all findings and information generated through a “stocktaking” process that involved a desk study of Prolinnova documents and evaluation reports, a questionnaire to 40 staff members of international organizations in agricultural research and development (ARD), self-assessment by the Country Platforms (CPs) and backstopping visits to five CPs. In 2014, the Prolinnova network saw a need to re-strategise in a changing context, and started this process by reviewing the activities it had undertaken and assessing its own functioning.
Most cocoa farmers in Ghana do not adopt research recommendations because they cannot afford the cost, therefore, yields are low. Integrated pest management (IPM) technologies that rely on low external inputs were tried with a group of farmers. The technologies included using aqueous neem seed extracts to control capsids; removing diseased pods to reduce blackpod incidence; controlling mistletoes, epiphytes, weeds; and managing shade. Although yields increased significantly, adoption was constrained by technical, social and economic factors.
Este libro, originalmente un documento de trabajo económico y sectorial del Banco Mundial, se inició como resultado de un taller internacional,“Desarrollo de sistemas de investigación para el apoyo a un cambiante sector agrícola”, que fue organizado por el Departamento de Agricultura y Desarrollo Rural del Banco Mundial en junio de 2004 en Washington, DC.
Les espaces ruraux périurbains des grandes villes d'Algérie vivent des transformations liées à trois facteurs combinés, parfois contradictoires : l'ouverture libérale, la redistribution de la rente pétrolière et l'évolution des espaces et des marchés urbains. Les exemples de la Mitidja centrale (entre Blida et Alger) et de l'Oranais en révèlent la diversité et les contrastes.
