In its report, 'Our Common Future', the World Commission on Environment and Development, (the Brundtland Commission), reflected the growing awareness among political leaders of the need to promote environmentally sound development by emphasizing the importance of agriculture sustainability. They defined sustainable development as "development which meets the needs of the present without compromising the ability of future generations to meet their own needs." In 1988, the Food and Agriculture Organization (FAO) clarified this definition to "Sustainable development is the management and conservation of the natural resource base, and the orientation of technological and institutional change in such a manner as to ensure the attainment and continued satisfaction of human needs for present and future generations. Such sustainable development (in agriculture, forestry and fisheries sectors) conserves land, water, plant and animal genetic resources, is environmentally non-degrading, technically appropriate, economically viable and socially acceptable."
