In 1955, G. Lacey, drainage and irrigation adviser at the Colonial Office, visited Sierra Leone as a consultant on water control and swamp development. Improved wetland management packages in Sierra Leone first introduced during the 1960s were elements in a broader strategy for Third World agricultural development sometimes termed the Green Revolution. The Green Revolution was a reaction to failures of large-scale development schemes during the 1940s and 1950s. In institutional terms the implication of arguments such as these is that Green Revolution research must be decentralised. This means a renewed emphasis on national research centres. In Sierra Leone local improved varieties emanating from Rokupr have consistently out-performed IRRI material, especially in upland conditions. To be responsive to localised needs and often highly specific ecological circumstances Green Revolution R&D must be securely rooted in local communities and interactive in character.
