Impacts of climate variability and climate change on regional crop yields are commonly assessed using process-based crop models. These models, however, simulate potential and water limited yields, which do not always relate to observed yields. The latter are largely influenced by crop...

In Sub-Saharan Africa (SSA) efforts to achieve food security are challenged by poverty, low soil fertility, unequal global trade relationships, population growth, weak institutions and infrastructure, and future climate changes and variability. Crop models are the primary tools available to...

Rainfed lowlands in inland valleys present a high potential for rice (Oryza spp.) production in West Africa. However, rice yield in the lowlands is, in general, low due to various constraints such as poor soil fertility, drought, iron (Fe) toxicity, and poor crop management practices. The...
