This report was commissioned by the Food and Agriculture Organization of the United Nations under a Technical Cooperation Programme with ASEAN: Scaling up Agroforestry for Livelihoods and Environmental Benefits in ASEAN. The study and publication of this report were coordinated by World Agroforestry (ICRAF) and the Southeast Asian Regional Center for Graduate Study and Research in Agriculture. The report preparation benefited from additional funding and technical support from the CGIAR Research Program on Forests, Trees and Agroforestry. This report is neither complete nor comprehensive but provides an overview of the advances in, and ongoing challenges to, agroforestry development and research in ASEAN, primarily, centring on initiatives over the last two decades . The report covers a range of thematic areas from landscape restoration and climate change adaptation and mitigation through governance to knowledge hubs as a means to identify opportunities and gaps in creating pathways for agroforestry uptake.Since agroforestry is not included in national reporting by either the forestry or agricultural sectors, this report has relied on primary analyses drawn from the literature, contributions from agroforestry researchers and expert practitioners, and survey data gathered from delegates to the ASEAN Working Group on Social Forestry. By focusing on gaps and opportunities in agroforestry landscapes, the report presents recommendations pertinent to the needs and interests of ASEAN Member States. To this end, the report aims to motivate actions among ASEAN Ministers and Senior Officials of Agriculture and Forestry along with local resource users, the private sector, researchers and others in expanding the scale of sustainable natural resource management through agroforestry. The outcomes of these actions will contribute to the Sustainable Development Goals, Paris Agreement and other societal targets for environmental and human well-being.
