This report documents lessons and experiences from the Reduced Emission from All Land Use (REALU) project, implemented by the ASB Partnership for the Tropical Forest Margins (ASB) hosted by the World Agroforestry Centre (ICRAF) from 2009 -- 2013 with financial support from Norway's Climate and Forest Initiative (NICFI) / the Norwegian Agency for Development Cooperation (NORAD). The report synthesizes findings and learning from exploratory work on landscape approaches towards emission reductions, the results of which aim to support actors in Reducing Emissions from Deforestation and Forest Degradation (REDD+), agriculture and climate smart landscapes. Given that this is an action research project, this report represents work in progress as the results and outcomes of the project are still being digested and further developed in the current phase of the project titled SECURED LANDSCAPES - Securing Ecosystems and Carbon benefits by Unlocking Reversal of Emissions Drivers in Landscapes.
