Lack of food remains the most serious threat to humanity's training. Its maneuver has been mobilized to combat this threat. In 1974, that Rome conference, Italy, the World Food Conference aimed primarily at eliminating hunger in the world. Today, after so many years, the phenomenon of hunger has expanded. The eradication of poverty is mainly based on the increase in agricultural production. But the agglomeration areas are limited and the objective is not easy to reach. We observe that cerial production is concentrated in seven countries that also provide the highest export quantity of world needs if, due to adverse climate change, the production of these countries would fall, makes importing countries particularly vulnerable, their situation may become dramatic. But as the terrestrial area is limited, the expansion of agricultural land is currently exhausted, and can only be done by deforestation from the wooded areas of the planet. It remains a potential source of future to increase agricultural productivity. Experts argue that the key issue of eradicating poverty and hunger in the world is nevertheless to increase agricultural production, where the most spectacular innovations will be made in the future to feed the over 80 million people who are born annually on Earth.
