Abstract:
... Maize (Zea mays L.) is a key food security crop in Eastern and Southern Africa (ESA). Maize yield gaps are large in the smallholder farming systems of ESA but can be closed by a combination of improved crop varieties and sustainable cropping systems. On-farm trials were conducted in five countries of ESA over a seven-year period to assess the effects of different cropping systems on maize producti ...

Abstract:
... Continuing environmental degradation amidst economic growth and population increase has underscored the desirability of pursuing sustainable intensification in agriculture. In theory, it would increase the volume of agricultural production without further degrading the natural environment or compromising the food security of the world’s poorest people. In practice, difficult choices involving trad ...

Abstract:
... Climate change will likely affect several of the dimensions that determine people’s food security status in Bangladesh, from crop production to the availability and accessibility of food products. Crop diversification is a form of adaptation to climate change that reduces exposure to climate-related risks and has also been shown to increase diet diversity, reduce micronutrient deficiencies, and po ...

Abstract:
... Agricultural mechanization is on the rise in Africa. A widespread replacement of manual labor and animal traction will change the face of African agriculture. Despite this potentially transformative role, only a few studies have looked at the effects of mechanization empirically, mostly focusing on yields and labor alone. This is the first paper that explores perceived agronomic, environmental, an ...
