ABSTRACT
INTRODUCTION The failings of the green revolution have shattered faith in the power of technology alone to solve development problems. Development has come to mean more than simply increasing production. Wider considerations of social equity and environmental conservation have proved to be equally important. Economists are also now realizing that the pursuit of economic growth has an environmental down side that must be given a cost in future budgeting (Pearce et al. 1989). Conservationists from all over the world are involving themselves in the struggle to win the battle to protect Africa's natural resources (Harrison 1987). Social scientists are also now revealing the value and importance of traditional land use systems for the preservation of people's livelihoods and the conservation of nature. Sustainable development has become a new and important goal for developers (Conway and Barbier 1988).
