This publication builds on the landmark 2018 Groundswell report to examine climate-induced migration in the Lake Victoria Basin to inform policy makers and practitioners about the urgency for near- and farsighted planning, policy, and action as an integral part of the development response. This report uses a quantitative and qualitative understanding of plausible future climate migration scenarios and proposes core policy direction and domains for action to better anticipate and prepare for the issue. It also provides strategic policy responses to guide countries in the Lake Victoria Basin to better anticipate and prepare for the expected 16.6 - 38.5 million internal climate migrants in the Victoria Basin countries by 2020.
