The best stimulus for economic development of a country is the food security of its population. This guarantee allows the population to break the vicious cycle of poverty, thereby improving their standard of living by diversifying its operations and increasing income. This explains why agriculture remains a fundamental instrument for sustainable development and poverty reduction. The world development report of 2008 showed that 75% of the poor people in developing countries are from rural areas and most of their sustenance are derived from agriculture. Guinea is one of the least developed countries in the world, but is actively engaged in improving rural livelihood and conditions. Since independence, the authorities have encouraged and supported farmers' organizations to solve common problems which they could not readily, economically and sustainably solve in isolation.
