Afrique septentrionale, Tunisie
Rangelands are recognized for their importance and value in providing society with valuable products and ecosystem services. In such ecosystems, effective management is needed for sustainable plant growth and survival in a context characterized by rainfall unreliability, poor soil nutrient status and high uncontrolled grazing. Therefore, cost-effective techniques/tools for slowing down and eventually reversing this degradation are needed. This paper promotes identifying and combining various tools for degraded arid ecosystems as strategies aimed for rangeland restoration/ rehabilitation.
