This study examines the price transmission mechanisms in the Bloemfontein beef market using the producer price and retail prices at four retail outlets collected over a period of 3 years. It further estimates the causality links between the producer and retail prices. The traditional (Engle-Granger) and standardized (Enders & Siklos) Augmented Dickey- Fuller procedures were used to test for co-integration and asymmetry in price transmission
These recommendations are a compilation of 2 regional studies at sub-Saharan Africa level which focused on research and technology transfer in the field of rainwater harvesting irrigatio nmanagement on one hand (section 3), and effective policy recommendations on the use of rainwater for off-season small-scale irrigation on the other (section 4). The regional studies upon which this transnational study is based come from the analysis of national studies in Ethiopia, Kenya, Mozambique and Zimbabwe.
At an average above 6.0 percent per year over the past two decades, Uganda' s growth rate was impressive by all standards. In parallel, poverty declined significantly, not only in urban areas, but also to some extent within the rural areas. This combination was possible because the key drivers of growth were labor-intensive services sectors, some of which are agriculture based. In fact, Uganda's growth process has reduced overall poverty faster than what has been observed in many other developing countries.
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.
Este documento resume las actividades desarrolladas durante el Foro “Experiencia de Investigación Agrícola para el Desarrollo: las Escuelas de Campo (ECAS)-Una Apuesta Innovadora hacia la Investigación Acción Participativa del Programa Agroambiental Mesoamericano (MAP) en la Región Trifinio” celebrado en San Ignacio, Chalatenango (El Salvador) entre el 25 y el 27 de octubre, 2011.
Food security is predicted toface considerable challenges in the upcoming period. This couldbe more profound in developing countries due to rapid societal change and ecological pressure in theseregions. Concerted efforts to deal with these challenges areof great importance, including accelerating th euse of improved agricultural input technology (IAIT) such as high yield varieties of seeds and improved fertilizer formulas. This type of innovation is more suitable to being introduced amongst developing countries farmers in order to increase their productivity.
Banana and plantain are one of the most important staple food crops and a significant source of income to smallholder farmers in the East African Great Lakes Region. Banana Xanthomonas Wilt (BXW) is a devastating bacterial disease that threatens smallholder production and livelihoods. We use a systems approach to describe how gender shapes roles and practices in the household, on the farm and in innovation processes. We draw on a case study in Burundi, where single disease stem removal (SDSR) has been introduced as a labour-saving package to reduce BXW incidence.
Innovation platforms (IPs) are a way of organizing multistakeholder interactions, marshalling ideas, people and resources to address challenges and opportunities embedded in complex settings. The approach has its roots in theories of complexity, the concept of innovation systems and practices of participatory action research. IPs have been widely adopted across Africa and beyond in recent years as a “must have” tool in a range of “for development” modes of agricultural research.
The development and scaling of orange-fleshed sweetpotato (OFSP) during the past 25 years is a case study of a disruptive innovation to address a pressing need – the high levels of vitamin A deficiency among children under five years of age in sub-Saharan Africa. When the innovation was introduced consumers strongly preferred white or yellow-fleshed sweetpotato, so it was necessary to create a demand to respond to that need. This was at odds with the breeding strategy of responding to consumers’ demands.
This article presents a multi-stakeholder framework for intervening in root, tuber, and banana seed systems and in other VPCs. These crops are reproduced not with true seed but with vegetative planting material (e.g., roots,tubers, vines, stems, and suckers), called “seed” in this article. Seed systems for VPCs need to be designed differently than those for true seed, and coordination among stakeholders in seed systems is crucial
