  7. Abstract:
  8. Lakes, marshes, and wetlands shrinkage and drying up due to natural and human driving forces is today one of the most important concerns in the world. Mahaarloo Salt Lake in southern part of Iran is (18 km far from south eastern of Shiraz ) drying-up and is faced with ecologic and environmental degradation. It recharges from western north by upstream basin of Shiraz and 3 rivers named Khoshk, Chenaarrahdaar, Soltaanabad and also from eastern south by Nazarabad river located in Sarvestan basin (Regional water org. of Fars 1382). In recent years, the shrinkage of Mahaarloo has been exacerbated by mismanagement of water resources, inappropriate land use, ignoring allocation of environmental flow and needs of ecosystems, municipal and industrial pollution in its watershed, and the prolonged drought started in 2008. . Mahaarloo Lake is one of the lakes with one of the biggest salt mines in addition to its ecosystem and environmental values for human and animal wellbeing. Regarding to its act on shiraz weather moisture, protecting around cover crops, biodiversity and promenade for people of Shiraz, Sarvestan and Kavaar and also problems occurred under drying (such as salty storms and bad sediments settled on base of the lake and their effect on people health) this research has been done to find ways to stabilize the lake to have water all seasons. In this study, a DPSIR model has been employed to derive the optimal management strategies for the restoration of the Lake. Cause-effect relationships have been identified by DPSIR framework and some sound scenarios have been developed based on them. The Driving force-Pressure-State- Impact-Response (DPSIR) approach, which is often used for the assessment of ecosystem systems using indicators describing the existing Drivers, Pressures, State, Impacts and Responses, can be used as a new interpretation in the description of policy formulation. The aim of this research is to indicate the overall economic efficacy of water resources uses and the Lake services by integrating ecological value. Water uses and ecosystem services into the DPSIR conceptual framework as an added value for policy making and management. Economical valuation (goods and services of the lake) are estimated. Building a dam and dividing the lake in two partition east sides for salt extract and west to collect water, making forest in the north and south margins to act as a barrier region and wind stopper to resist against weather movement and making longer interaction time between dry and humid air, Transporting water from Persian gulf, studying on irrigation and cultivation and giving advices to reduce water consumption, have been studied. The Achieved results show that with building a dam, making forest and modifying irrigation and cultivation the lake can be improved improve and there is no need to transport water from Persian Gulf
