Transferability of Green Revolution in Sub-Saharan Africa: Impact Assessment of Rice Production Technology Training in Northern Ghana

抄録

This paper examines the transferability of Green Revolution technologies in Sub-Saharan Africa through the assessment of a technology training project in Northern Ghana. The main results are as follows : First, the training project successfully improved the adoption rates of four technologies : dibbling in line/drilling, bund building/repairing, modern varieties, and fertilizer usage. Second, the adoption rates became higher in villages where longer time had passed since the training. Third, inter-village diffusion of technology took longer time than intra-village one.
