Revised Summary Report on Developing CGIAR System Priorities for Research por CGIAR Science Council

“…The priority areas for research respond to the continuing challenge of maintaining sustainable food production systems, and the new agricultural paradigms encouraging competitiveness, and addressing the situation of the poor in marginal lands. The Science Council considers that the reviews undertaken of the current emphases in CGIAR research, the establishment of the future context and the widely participatory process followed for establishing potential new areas for research, provide the basis for the next steps - the establishment of overall CGIAR System Priorities for the period to 2010.The Summary Report further defines the subsequent activities to be undertaken, and a proposed schedule, through which new CGIAR System Priorities for research may be developed. …”

Beef and dairy value chains in Senegal: Problems and Opportunities por Chan, Derek, Houessionon, Prosper, Sow, Fafa, Perin, Lucie, Krendelsberger, Alexandra, Seck, Ibrahima, Wane, Abdrahmane, Whitbread, Anthony M., Worou, Nadine

“…The most significant problems faced are increased competition for fewer resources (namely pasture biomass and water) which, compounded with high feed prices and tight margins, contributes to conflict. There are opportunities to improve the marketability of dairy products and milk and beef productivity by improving connections to the market, testing different stabling and feed practices, adapting climate information services to producers’ needs, identifying and rehabilitating transhumance corridors, improving accessibility to feed, and introducing better and more veterinary checks.…”

Understanding smallholder irrigation in Sub-Saharan Africa: results of a sample survey from nine countries por Shah, Tushaar, Verma, Shilp, Pavelic, Paul

“…Motor-pump-irrigation farmers reported the highest net value added per acre and per family worker, with gravity-flow and manual-irrigation farmers earning marginally more than rainfed-only farmers. In addition to making affordable pumps more readily available, improving the availability of working capital, enhancing security of tenure and ensuring the availability of affordable fuel are all likely to accelerate smallholder irrigation development in Sub-Saharan Africa.…”

Digital innovations and agricultural transformation in Africa: Lessons from Kenya por Tabe-Ojong, Martin Paul Jr., Abate, Gashaw T., Abay, Kibrom A., Spielman, David J.

“…Efforts to better integrate food systems—defined here as the constellation of actors and their activities originating from agriculture, livestock, forestry, or fisheries, as well as the broader economic, societal, and natural environments in which they operate, including the production, aggregation, processing, distribution, consumption, and disposal of food products (Dwivedi et al. 2017; FAO 2018; Njuki et al. 2021)—will depend partly on how digital technologies can be used to bolster engagement, coordination, and innovation among a wider and more inclusive set of actors, including marginalized and vulnerable groups (Benfica et al. 2021).…”

Land Management Options in Western Kenya and Eastern Uganda por Delve, Robert, Ramisch, Joshua

“…These problems have been ascribed to many different causes: social (e.g., marginalization of the poor and women), political (e.g., structural adjustment programs), economic (e.g., poor availability and/or high prices of inputs, limited market opportunities), biological (e.g., increasing population and reducing land sizes), and physical (e.g., climatic change).…”

Prediction of the impact of logging activities on forest cover: a case study in East province of Cameroon por Mertens, B., Forni, E., Lambin, E.F.

“…Results showed that, in one site, half of the very high rent areas have already been logged indicating that the unlogged high rent area is scarce and the low rent or marginal forest area remains largely unlogged. However, this was not the case throughout the study area as shown by the observations at the other site. …”
