APPENDIX F. Interview with Ma Veasna project coordinator of the ILFARM project. Held 18th of October 2008 at the CEDAC office in Prey Veng city, Prey Veng province, Cambodia. Marc Dumas-Johansen: How many SRI concepts do farmers follow in average and which ones? Ma Veasna: Farmers normally use big seedlings for transplanting, leveling of land, use more compost than in traditional fields, planting the rice plants in strait lines and do weeding. Most farmers carry out all these techniques. Good farmers do like this. Lazy farmers do not do so much. Marc Dumas-Johansen: What is the disadoption rate of SRI farmers? How many farmers will not practise SRI after some years? Ma Veasna: Most farmers stop with SRI after three to four years because they are used to working with traditional rice farming and then they mix the two concepts and stop with SRI. SRI also means more work for them, so they gradually go back to traditional rice farming. Marc Dumas-Johansen: What do farmers feed their animals? Ma Veasna: Grass and rice straw. They also eat tree leaves. This is mostly for cows. Marc Dumas-Johansen: How many SRI farmers are there in the in total in the project and how many in each commune? Ma Veasna: There are 160 farmers in the three target communes but the number is growing. Chourn Ampol commune has 25 SRI farmers and Kdoung Reay commune has 70-78 sri farmers. The most successful farmers are found in this commune. The total land of SRI is 8 ha in these two communes where farmers are medium and small farmers.. Marc Dumas-Johansen: Where do farmers get their seeds from? Ma Veasna: They use their own seeds and save seeds from last year’s harvest. They keep the seed stocks from their parents. Some farmers buy seeds from outside. Marc Dumas-Johansen: What trees are used in the project and how many? Ma Veasna: 500.000 trees in total will be mobilized by the project. Multiple use trees and fruit trees will be used. 87
