INTENSIFICATION OF RAINFED LOWLAND RICE PRODUCTION IN WEST AFRICA: PRESENT STATUS AND POTENTIAL GREEN REVOLUTION
Authors:Takeshi SAKURAI
Abstract:
The objective of the current paper is to explore the factors influencing the expansion and intensification of rice production in rainfed lowland sites. The village/lowland‐level data show the following: (1) the expansion of lowland rice cultivation has been driven by population pressure and accessibility to the market; and (2) the adoption of water control technologies is enhanced by the existence of immigrants and accessibility to the market. Rice cultivator data show that investment in water supply canals is influenced by land tenure security and that the canals enhance yield. This suggests that investment in water control technologies in rainfed lowland is necessary to realize a rice Green Revolution. Considering the fairly high average yield already achieved with water control technologies and the vast area of lowlands without water control technologies in rural area, there is a high potential of a rice Green Revolution in rainfed lowland in West Africa.
