Tanzania fertilizer use increased after intervention, but changes were not sustained, study shows
Smallholder farmers in Sub-Saharan Africa tend to use very small amounts of fertilizer, limiting their crop productivity. A 2016 intervention in Tanzania increased farmers' fertilizer use and their crop yields. However, a follow-up study from an inte.....»»
Polarization and risk perception could play important roles in climate-policy outcomes
Times of crises often call for strong and rapid action, but in polarized societies, strong top-down policies can backfire......»»
Extended maternal care is a central factor to animal and human longevity, modeling study suggests
The relationship between mother and child may offer clues to the mystery of why humans live longer lives than expected for their size—and shed new light on what it means to be human......»»
