This document summarizes a study on the potential impacts of climate change on land use in Laos. It finds that temperatures in Laos increased over the 20th century, especially in the south, and are projected to continue rising substantially by 2020 and 2050 according to climate models. Rainfall trends are less clear but also appear to be changing. These climate shifts could impact suitable areas for crops like sugarcane and coffee. Analysis of satellite data from 2000 to 2009 detected land use and vegetation changes across the country. The study recommends more integrated and resilient farming systems to prepare for a hotter, drier future from climate change.
