Abstract

Ahmed Karmaoui

The oases of the Draa are part of the biosphere reserve recognized by UNESCO, 2000. These oases are agro systems located in the Saharan region of southern Morocco. They are the main sources of livelihood of the indigenous population. The sustainability of the oasean system for centuries has made him a rich and resilient ecosystem. Despite its aridity and isolation, the population had always been able to adapt and optimize natural resources, which are scarce. However, during the last 50 years extreme events (droughts, floods and locust attacks) have become increasingly frequent, and have a considerable threat. The article is a diagnostic of resilience state and the impact of extreme events on food security and even existence of this heritage.
