The development of a system for the monitoring of agrobiodiversity in situ or on-farm is of paramount importance for every country and urgently needed. Its importance arises from the fact that by and large the greatest amount (inter- and intra-specific levels) of agrobiodiversity (plants and anim...

Soaring international food and energy prices and the resulting volatility in markets is alarming many African policy makers. The domestic production of wheat in many countries suffers from lack of policy support and donor neglect resulting from the perception that Africa cannot competitively prod...

Soil fertility depletion is considered one of the main biophysical limiting factors for increasing per capita food production for smallholder farmers in Sub-Saharan Africa. The adoption and diffusion of sustainable agricultural practices (SAPs), as a way to tackle this challenge, has become an im...

Rice productivity and sustainability are continually threatened by abiotic stresses, particularly in the era of global climate change. In severe cases, 100% yield loss can be experienced due solely to abiotic stresses, such as drought. The situation may become worse due to climate change that may...

Dissemination or extension of technologies among the farmers is a complex issue. More often than not the scientists, having developed and tested the technologies, are not able to transfer these to the farmers widely. W hy the farmer is not ready to adopt the new technology is an issue that haunts...
The present study takes into account the role of potatoes in the global food system and seeks to contribute to the current discussion on agricultural research for food security. To this end, an updated and rebuilt version of the IMPACT-WATER model (Rosegrant et al., 2008) is applied to assess the...

The climate change has been recognized by the world community as a potential threat to environment, ecosystem, and development. The impacts are not spatially similar and Asia s rural poor are more challenged of its consequences. ICRISAT with support of ADB have tracked the climatic trends, identi...

Recent and current efforts at IITA to assess risks due to the various biotic stresses, arthropod pests and diseases, are presented for different cropping systems. In the case of cassava arthropod pests, the focus is on temperature-mediated interactions between the pest and its natural enemy which...

Current projections suggest that the impacts of warmer climates on smallholder production by the middle of this century, are excpected to be mainly negative. Both the livelihoods and food security of smallholder households can be improved through suitable strategies for handling climate- induced ...
