This Guidance Note was drafted to document lessons learned in the three project countries and in doing so, it provides a step-by-step practical guide for countries in post-crisis situations to undertake Integrated SEAs. The Integrated SEA approach builds upon current SEA practices, while placing greater emphasis on integrating disaster risk and climate change impacts into a participatory data collection, mapping and planning process. This publication provides practical guidance on how to manage the process of assembling data and obtaining consensus from a wide range of actors to produce robust and widely accepted ‘Opportunity Maps’ for sustainable reconstruction and development. Recommendations from Integrated SEA processes should aim to be institutionalized into formal land-use planning processes. As such, Post-Crisis Integrated SEAs can be considered a bridge between post-crisis humanitarian action and sustainable development planning.
