Food without fire: Environmental and nutritional impacts from a solar stove field experiment

American Journal of Agricultural Economics, EarlyView.
Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Production, breeding and potential of cowpea crop in Brazil. [PDF]

, 2013
About 50 years ago cowpea was reported as a relatively minor tropical legume. However, in the last years, it has been emerging as one of the most important food legume of the 21st century (SINGH, 2010). Brazil is not out of this panorama.
