This study, evaluates the intervening influence of extension services on livelihood impacts of drought tolerant maize adoption and the potential mechanisms through which extension can enhance or reduce impact of drought tolerant maize using cross-sectional household level data from smallholder maize producers in Zimbabwe. Specifically, we examine whether access to agriculture extension services influences the relationship between livelihood outcomes and the adoption of drought-tolerant maize varieties in selected districts in the country
Les populations rurales sédentaires de la commune de Hombori (Mali) pratiquent presque toutes la culture de mil associée au petit élevage non transhumant. Au-delà des contraintes environnementales d’une région semi-aride, le maintien de l’agro-élevage repose sur une double maitrise, des territoires et des ressources, l’une et l’autre ne pouvant se confondre.
Le sud du Brésil qui possède un bon potentiel naturel en raison de son climat chaud et humide et de son relief favorable est voué principalement à l’élevage et aux cultures de soja, de riz et de maïs. Cette région, comme d’autres au Brésil, participe à la production de denrées agricoles pour le marché national et international. Elle est ainsi soumise à l’intensification des pratiques dont les impacts sur l’environnement sont notoires. L’étude concerne plus particulièrement le bassin versant de l’Ibicuí (46 800 km²), situé dans le sud-ouest de l’État de Rio Grande do Sul.
L’agriculture de conservation (AC) obéit à trois principes : travail du sol minimal, couverture du sol permanente et multiculture. Partant de ses avantages avérés pour l’écologie du sol, la séquestration de carbone et son adoption massive dans quelques régions du monde, elle est présentée par ses promoteurs comme un système durable convenant à tous contextes. Dès lors elle a été mondialement diffusée au nom du développement durable.
There is great untapped potential for farm mechanization to support rural development initiatives in low- and middle-income countries. As technology transfer of large machinery from high-income countries was ineffective during the 1980s and 90s, mechanization options were developed appropriate to resource poor farmers cultivating small and scattered plots. More recently, projects that aim to increase the adoption of farm machinery have tended to target service providers rather than individual farmers.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
This report is part of the AFRHINET project under the ACP-EU Cooperation Programme in Science and Technology (S&T II). The overall aims of the project are to enhance options for sustainable integration of rainwater harvesting for irrigation through understanding adoption constraints and developing networks for capacity building and technology transfer. The African partners are Addis Ababa University and WaterAid-Ethiopia in Ethiopia, University of Nairobi and ICRAF-Searnet in Kenya, Eduardo Mondlane University in Mozambique, and University of Zimbabwe and ICRISAT-Zimbabwe in Zimbabwe.
This study has been produced with the overall goal to document and analyse exisiting best practices in the field of RWHI management in sub-Saharan Africa, with a special focus on Ethiopia, Kenya, Mozambique and Zimbabwe. This is meant to determine the suitability of RWHI management under multivariate biophysical and socioeconomic conditions. The best practices include specific information and know-how on the performance, cost-efficiency and impacts of RWHI technologies.
These advanced training materials have been produced to foster the capacity of practitioners from private, nongovernmental and public sectors on one hand, and academics and scientists on the other, to practically implement cost-efficient RWHI technologies and practices in arid and semi-arid areas. Therefore, these training materials intend to provide the required information to support proper planning, design and construction of cost-efficient RWHI technologies and practices, with special emphasis on the specific problems encountered in Ethiopia, Kenya, Mozambique and Zimbabwe.
These training materials have been produced to foster the capacity of key members of local communities to practically implement RWHI systems in a cost-efficient manner. The specific target group of these capacity building materials are local community members who are directly involved in the replication and scale-up of RWHI technologies and practices, i.e.
