11 Benefits of agroforestry Shantea: same growth in all treatments Shantea have not harvested yet and it will be continued to evaluate for next period of experiment Mulato: 11.5 ton/ha/year Ghine: 14.5 ton/ha/year grasses were used for livestock Increase land use efficiency Soil conservation

12 2. Macadamia + Coffee+bean Mai Sơn-Sơn La and Tuần Giáo-Điện Biên Established: 6/213

14 Benefits of agroforestry -Growth of coffee intercropped with macadamia and bean were better than growth of coffee intercropped with bean Coffee will be harvested in 215 -Growth of macadamia were the same in all treatments Macadamia have not yielded yet and it will be continued to evaluate for next period of experiment Yield of bean reached.28 ton/ha (4.5 millions VND/ha) - Increase land use efficiency - Increase soil nutrients - Soil conservation

17 Benefits of agroforestry Coffee and plum have not yielded yet and it will be continued to evaluate for next period of experiment Yield of bean reached.16 ton/ha (2.5 millions VND/ha) Ghine: 9.7 ton/ha/year Grasses were used for livestock Increase land use efficiency Soil conservation

18 Outlook Continue to monitor and analyze the trials include economic efficiency. Evaluation ability to minimize erosion of grooviest systems Provide recommendations to improve smallholder livelihoods in the Northwest Vietnam
