This report is to complete the terms of reference of the project signed between General Directorate of Rubber (GDR/MAFF, Kingdom of Cambodia) and Cirad on 22 June 2018 and called “Implementing Good Agricultural Practices (GAP) in Cambodia for a Climate Smart Rubber Production: Training sessions”, under a funding provided by Agence Française de Développement (AFD). A seminar was organized by GDR from 19 to 22 June 2018 in GDR head office in Phnom Penh, followed by a visit of Cambodian Rubber Research Institute (CRRI) experimental station in Tboung Khmum Province on 23 June 2018. The document report addresses 5 terms of reference, as stated in the contract: • TOR1. A reminder of the definitions of the concepts of Good Agricultural Practices (GAP) and Climate Smart Agriculture (CSA). • TOR2. A reporting of the activities of Cirad in each area of expertise: Agro-socioeconomics (Dr Bénédicte Chambon), agrophysiology and agronomy (Dr Eric Gohet and Dr Régis Lacote), ecophysiology (Dr Yann Nouvellon), soil fertility management and crop diversification (Dr Florent Tivet), focusing mainly on capacity building in each area. • TOR3. A drafting of a GAP (Latex harvesting system) manual, understandable by farmers. • TOR4. Proposed supporting experimentation (managed by CRRI) • TOR5. Proposals for a long-term cooperation between the three partners of the project (GDR, CRRI and CIRAD) for tackling the adaptation of rubber cultivation to the different rubber cultivation areas of Cambodia, taking into account the diversity of socioeconomic contexts.
