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...

This paper examines the high value chains (HVC) for green bean exports from Africa to identify the critical points at which exporters exercise great caution in preventing produce contamination with pathogens and pesticide residues. It then examines the control points that pose greatest threat to...

This paper examines the effects of compliance with developed country pesticide standards (DC-PS) on pesticide-related health costs and morbidity of developing country fresh vegetable growers. DC-PS require that farmers i) only use approved pesticides (usually less toxic to humans than ones used...

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...
