Many assessments of climate change impacts on global crop yields project declines as early as the 2020s. Losses are projected to increase with time, up to 50% by the 2080s. We carry out a systematic global review and compare published projections of climate change impacts from 34 studies and ∼450...

The impacts of climate change on crop yields, as projected by a slew of impact assessments carried out since the 1980s, have brought the issue of future food insecurity to the fore. A meta-analysis of ~27,000 data points from studies published over the last four decades reveals that at country le...

Agricultural research for development has made important contributions to poverty reduction and food security over the last 40 years. Nevertheless, it is likely that both the speed of global change and its impacts on natural and socio-economic systems are being under-estimated. Coupled with the m...

Climate change will have far-reaching impacts on crop, livestock and fisheries production, and will change the prevalence of crop pests. Many of these impacts are already measurable. Climate impact studies are dominated by those on crop yields despite the limitations of climate-crop modelling, wi...

In developing countries, drought can cripple communities. Its impact is often long-lasting, especially if smallholders have to sell off farming equipment in order to survive the loss of crop income. And in the developed world, drought in a major food-producing region can push up food prices world...

Intermediaries are seen as important actors in facilitating payments for environmental services (PES). However, few data exist on the adequacy of the services provided by intermediaries and the impacts of their interventions. Using four PES case studies in Vietnam, this paper analyses the roles o...
