The Regional forum on Agroecology Futures represented the closing session of the ACTAE Project1 “Toward an agroecological transition in South East Asia” funded by AFD (Agence Française pour le Développement). It took place in Siem Reap, Cambodia, on 6th – 8th of November 2018. It has been the biggest event on agroecology in the Mekong Region since the Regional Symposium organized by the UN Food and Agriculture Organization (FAO) in November 2015, in Bangkok, Thailand. Over 260 participants from 21 nationalities gathered to discuss the futures of Agroecology during an unprecedented Regional Forum. The event was co-organized by the General Directorate of Agriculture (GDA) of Cambodia, CIRAD and GRET in a joint effort to promote agroecology. The overall aim of the forum was to build a momentum around the different dimensions of Agroecology that should be addressed, and consolidate a Regional Agroecology stakeholders' coalition by wrapping up the achievements of ACTAE project (Towards an Agroecological Transition in South-East Asia, AFD) and discussing the future of regional initiative in Agroecology. Over 3 days, the participants could learn, share and network through 74 presentations in plenary and parallel sessions, an innovation and knowledge fair (with over 20 booths), a poster session (25 were presented) and a seed swap where more than 60 different plant species were exchanged. Agroecology being diverse and multidimensional, a broad range of issues were addressed such as the fundamental role of crop biodiversity, the highly preoccupying status of agrochemical use in the region, the need for appropriate-scale mechanization, the importance of innovative and participatory intervention mechanisms, the recognition and integration of Indigenous Knowledge, the capacity building of the new generation, the marketing of agroecological products… A panel discussion bringing together representatives from AFD, the UN Food and Agriculture Organization (FAO), the Livelihood Trust
