Demand for food is sure to increase because of increase in population and increase in incomes, even though these demands and the ability to meet the demand are not equal in all communities. Indeed, Today’s global agricultural production is enough to feed the current world population with both necessary technologies and multi-lateral environmental agreements are available for help to meet development and conservation needs. However, hunger, poverty and environmental degradation persist even as concerns about global human security issues continue to increase.
Moreover, the last decades provided uncompromising evidence of diminishing returns on grains despite the rapid increase of chemical pesticides and fertilizer applications (Sanders, 2006), resulting in lower confidence that these high input technologies will provide for equitable household and national food security in the next decade. Overall, global cereal production is declining mainly among the major producing and exporting countries (*Source : FAO 2007).
