Assessing capacity and providing sustainable livelihood strategies in the Zagros region with emphasis on legal and environmental aspects (Case study: Dena watershed)

The aim of this study is to assess the potential of Dena watershed and provide sustainable livelihood strategies. This is a practical goal that used a combined model to assess the strength of the Central Zagros region. First, ecological parameters were identified to assess the ecological potential, and then layers were prepared by georeferencing, digitization, and timing. The study used data from Landsat 7 and IRS satellite imaging images. The layers overlapped and classified in the ArcGIS software, version9.2. In the next step, SCORE technique and reference to expert opinions were used to formulate the strategies. The results showed that 20.9% of the region needs protection and 19.8% is suitable for forestry. The lowest percentage of suitable use for the region belongs to the protection of water resources and then residential development. Analysis of the internal and external environment of sustainable livelihood management in the study area shows that opportunities and strengths have a higher average score than restrictions and risks. Finally, 11 management and legal strategies for sustainable livelihoods were developed in the Dena watershed.
