Résumé
Sixteen papers present case studies of various innovative alternatives to slash-and-burn that have been adopted in tropical uplands agriculture, especially in Indonesia; assess these promising upland technologies; and examine how these innovations came about. Papers discuss technical innovations and livestock production (Federic Lancon and Ibrahim Hasanudin); on-farm reservoirs for supplemental irrigation (Pascal Perez); constraints to adoption of food-crop technologies in upland areas (Lancon); the introduction of vegetable production (Lancon and Hasanudin); ginger and annual crops in tree-based agriculture (Francois Ruf, Yoddang, and Syarifuddin); tree crops and paddy cropping systems (Ruf and Yoddang); transition from alley cropping to cashew farms (Ruf and Lancon); coffee and agroforestry systems (Ruf and Yoddang); vanilla on coffee farms (Ruf, Yoddang, and Syarifuddin); intensive orange production (Lancon and Hasanudin); improved rubber agroforestry systems (Eric Penot); pesticides and the control of the cocoa pod borer (Ruf and Yoddang); the adoption of cocoa (Ruf and Yoddang); replanting after imperata cylindrical (Ruf and Yoddang); and price and nonprice factors in a green revolution (Ruf).
