The agricultural sector alone is capable of initiating growth in countries where it contributes for high proportion of the Gross Domestic Product. This particular trait is recorded in many African countries. The countries have to make their agricultural sector competitive and then better support their national GDP. They had also significant assets in the rural sector and food security, even if they are still poorly exploited. Particular emphasis may be placed on agro-ecological conditions for agriculture and the existence of international organizations. But it is clear that this sector, '' lungs of their economy '' is braked in its tracks in recent years. In addition to climate change issues those are the watchwords of contemporary debates, the agricultural intensification by using chemicals inputs in the production cycle are also highlighting. Furthermore, development policies implemented to increase production of cash crops such as cotton and cashew are not really suitable. It is important to note that all of these factors threaten the food security of the population. This book, through a number of developed topics, clarifies these issues and suggests some solutions approaches.
