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...

Adaptation must become a priority for policymakers around the world. Research and other initiatives must begin now as they can take up to 20 years to deliver results.


Campbell, Bruce M.[Climate change: Call for UN to act on food security]Climate change: Call for UN to act on food security

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...

When negotiations began on the post-2012 global climate change regime, forests and forestry returned to the international stage (Angelsen, 2008). I ask whether it is the time now for agriculture, and whether climate change initiatives in forestry and agriculture can contribute to poverty alleviat...

If climate-smart agriculture (CSA) is meaningfully to address the development challenges posed by climate change, effective approaches will be needed to scale up research findings. Here, eleven case studies are used to exemplify scaling-up strategies based on (1) value chains and private sector i...

Climate change impacts on agriculture have become evident, and threaten the achievement of global food security. On the other hand, the agricultural sector itself is a cause of climate change, and if actions are not taken, the sector might impede the achievement of global climate goals. Science-p...
