description We are nearly 7,3 billion people in the world and we will probably be more than 9,5 billion in 2050. The increase in purchasing power in some emerging countries results in a growing consumption of animal products. As we need to produce from three to ten plant calories to get one animal calorie, it will be necessary to double the vegetable production in the next 35 years in order to meet this growing demand in foods, while taking care not to damage the fertility of the agroecosystems on the long term. Some agricultural systems based on agro-ecology are already available in order to increase significantly the yields per hectare without excessive use of fossil fuels and pesticides. But only family farming systems rooted in their local environment will be able to make the best use of natural productive potentials.
