Land-use and land-cover changes (LULCC) have a recognized effect on climate, both in terms of changes in the carbon cycle due to changes in vegetation and soil carbon (biogeochemical effects), but also through variations in the surface energy budget mediated by reflected sunlight, evapotranspiration, canopy structure, etc. (known collectively as biophysical effects). Biophysical effects result in changes in seasonal and/or annual air surface temperatures and precipitation with prevalently local to regional effects, which depend – in sign and in magnitude – on the latitude and ecosystems where they occur. Although biophysical impacts on climate can be relevant at the regional scale, the international UNFCCC process focuses on the biogeochemical effects. We have produced a synthesis of the existing knowledge on temperature and precipitation changes due to biophysical effects of LULCC in order to provide an evidence base to policy makers on which to judge the need for an assessment of biophysical changes caused by land-based mitigation/adaptation policies. One objective of LUC4C is to provide a tool for policy makers that supports quantification and monitoring of LULCC biophysical effects of land use change; this tool is under development, the review presented here serves as a first step towards it.
