More homogeneity and fires are coming for boreal forests

,
Secondo uno studio della Wageningen University le foreste dell'emisfero settentrionale saranno sempre più simili tra loro a causa dei cambiamenti climatici. In questo modo aumenterà anche il rischio di incendi boschivi

Crop diversification supports nitrogen sequestration (but not carbon)

,
Diversifying rotations does not promote carbon storage but increases nitrogen availability with positive impact on soil and climate, a Iowa University study has found

Efficient use of nitrogen is needed to protect environment and health, says FAO

,
Nitrogen, the UN agency remarks, is an essential element but also a contaminant. Its intake to the soil is likely to quadruple by the end of the 21st century
In tropical forests, says a study, the addition of nutrients would increase shoot biomass by 26% and growth rate by 14%.

Accumulation of nutrients threatens tropical forests

,
According to a study, the inflow of nutrients would eventually provide a competitive advantage to some tree species resulting in a loss of biodiversity

Agriculture and irrigation affect rainfall in the U.S. Midwest

,
According to a study, the interaction between groundwater resources, crops and irrigation impacts the rate of rainfall recycling with a direct effect on agricultural management and water availability

Climate change reduces rice quality in China and Japan

,
According to a Chinese study, the quality of rice has been deteriorating for decades, and the phenomenon is unlikely to slow down over this century
