AGROECOLOGY
Hunger and malnutrition affect nearly 800 million people in the developing world. Those problems, however, are not due to an absolute scarcity of food, but to the more complex issues ofwho grows food and how and where it is grown, how it is distributed, and finally, who has access to it.
Since 1960, world food production has grown faster than population, mainly because of de greenrevolution, an effort to increase crops in agriculturally less advanced region of the world. But, this attempt has resulted in failure because it was based on improved seeds which required a heavyuse of fertilizers, pesticides, irrigation and machinery. Consequently the environmental and socio-economic impacts have been negative, and most importantly, the project has not ended world famines.The alterative is a viable and productive small farm agricultural system using the principles of agro ecology. This scientific discipline studies agricultural systems from an ecological andsocio-economic perspective. It integrates indigenous knowledge with modern technical knowledge and emphasizes the interrelationship of all the elements in an agro ecosystem, including human elements. In contrastto the conventional green revolution approach that focuses on uniform technologies and heavy- use of chemicals, agro ecology is based on plant and animal biodiversity, minimal dependence onagrochemicals, natural pest control, and regeneration and conservation of resources.
