Drivers of household food availability in sub-Saharan Africa based on big data from small farms
Achieving sustainable food security (i.e., the basic right of people to produce and/or purchase the food they need, without harming the social and biophysical environment) is a major challenge in a world of rapid human population growth, large-scale changes in economic development and in the face of climate change.
In sub-Saharan Africa (SSA), production on smallholder farms is critical to the food security of the rural poor and contributes the majority of food production at the national level.
