标题：PROGRESS AND PROBLEMS IN PROMOTING HIGH EXTERNAL-INPUT TECHNOLOGIES IN SUB-SAHARAN AFRICA: THE SASKAWA GLOBAL 2000 EXPERIENCE IN ETHIOPIA AND MOZAMBIQUE
摘要：Critics argue that high external input technologies are too costly for African farmers, and that pilot programs to promote them are economically unsustainable. This paper assesses Sasakawa-Global 2000 programs in Ethiopia and Mozambique; budgets, yield models and subsector analysis help explain the radically different country results and prognoses for sustainable adoption.
