The processes underlying environmental, economic, and social unsustainability derive in part from the food system. Building sustainable food systems has become a predominating endeavor aiming to redirect our food systems and policies towards better-adjusted goals and improved societal welfare. Fo...
Background: Cultivation is the most appropriate management option when both demand and harvesting of wild plant species increase beyond natural production levels. In the current study we made the assumption that, besides the intrinsic biological and ecological characteristics of the species, the ...
Discusses the historical context of ILCA's research, the principal types of animal production systems and the stages in ILCA's farming systems research. Describes the smallholder farming in the Ethiopian highlands & humid zone, the agropastoralists of the sub-humid zone, systems research in pasto...
Describes possible methods of allocating research resources based on different analytical models. Presents a brief review of models proposed; and some evidence about current agricultural and livestock reserch in sub-Saharan Africa. Also presents emperical tests of which variables might be importa...
Using a global atmospheric chemistry model, we have quantified for the first time, intercontinental transboundary contributions to crop ozone exposure and subsequent yield reductions in the Northern Hemisphere. We apply four metrics (AOT40, M7, M12, W126) to assess the impacts of 100% reductions ...
Climate change threatens staple food production and human livelihoods, particularly in vulnerable environments in Africa. Poorly adapted cropping systems increase the risk of poverty and hunger. Existing genotypes adapted to local conditions may not be suited for cropping systems responding to fu...
Integrated Assessment studies have shown that meeting ambitious greenhouse gas mitigation targets will require substantial amounts of bioenergy as part of the future energy mix. In the course of the Agricultural Model Intercomparison and Improvement Project (AgMIP), five global agro-economic mode...
