Sustainable agricultural practices (SAPs) that lead to an increase in productivity are central to the acceleration of economic growth; this will alleviate poverty and help to overcome the recurrent food shortages that affect millions of households in Africa. However, the adoption rates of SAPs re...

The paper contributes to an understanding of the determinants of food security with a bias on the link between gender of household head and food security using detailed farm household and plot level survey data from 30 divisions in rural Kenya. Both parametric and non-parametric econometric techn...

Crop residue use for soil mulch and animal feed are the two major competing purposes and the basic source of fundamental challenge in conservation agriculture (CA) where residue retention on farm plots is one of the three CA principles. Using survey data from Kenya and applying bivariate ordered ...

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...

This study uses geo-spatial crop modeling to quantify the biophysical impact of weather extremes. More specifically, the study analyzes the weather extreme which affected maize production in the USA in 2012; it also estimates the effect of a similar weather extreme in 2050, using future climate s...
