Increased grazing pressure threatens the most arid rangelands

A new study published in Science reports results from the first-ever global field assessment of the ecological impacts of grazing in drylands. An international research team has found that grazing can have positive effects ...

Finding more sustainable ways to cultivate rice crops

Rice farmers depend on phosphorous fertilizers to maximize their yields of this major staple food, which helps nourish more than half of the world's population. However, there is a finite supply of the nutrient available ...

Global hotspots for soil conservation are poorly protected

Current protected areas only poorly cover the places most relevant for conserving soil ecological values. This is the conclusion of a new study published in the journal Nature. To assess global hotspots for preserving soil ...
