Climate change is a key threat to agriculture. Modelling is fundamental to assessing its potential impacts. This collection summarises the wealth of research on improving climate impact models and their use in assessing impacts on different regions. Modelling climate change impacts on agricultural systems reviews research on developing models in areas such as improving data flows, incorporating genetic information and dealing with uncertainty. This collection also reviews what we know about potential climate change impacts on regional agricultural systems such, Europe, North America, Latin America, Australia and Oceania, as well as different regions in Asia and Africa.

It has been suggested that agriculture may account for up to 24% of the greenhouse gas emissions (GHGs) contributing to climate change. At the same time climate change is threatening to disrupt agricultural production. This collection reviews key research addressing this challenge. Climate change is the biggest challenge agriculture faces. Part 1 of this collection reviews current research on the impacts of climate change on agriculture, such as the effects of increased temperatures, as well as the ways these impacts can be modelled. Part 2 assesses what we know about the contribution of agriculture to climate change, including the impacts of both crop and livestock production as well as land use. Part 3 surveys mitigation strategies to achieve a more 'climate-smart' agriculture such as the role of integrated crop-livestock and agroforestry systems.
