with the objective of providing an alternative approach to increasing food security in Africa. CABDA proceeds through specific areas of intervention such as the introduction of drought-resistant crops and new methods of food production such as agro-forestry.

Northern Mali, southern Libya, southern Algeria, eastern Chad were being examined in part of an ongoing project to find viable drilling as the region's nations try to find new water sources to keep up with their growing demand. Algeria, Burkina Faso, Mauritania, Morocco, Mozambique, Niger have shown a major interest in the further development of this resource lead local industry, which could prove a valuable asset for nomads, local farmers and townsfolk alike in the years to come.
