Investigating and identifying the effects of rural wastewater in Dena protected area and presenting an environmental management pattern

The purpose of this study was to identify the effects of discharge and discharge of wastewater from rural communities on biodiversity in the Dena Protected Area in the Central Zagros. This research is an applied grandson that has been done by library and field method. GIS tools and Landsat satellite have been used to extract and draw maps. In order to develop a comprehensive management plan and determine objectives and operational plans, the approach (SMART + P) and factor analysis method were used. For this purpose, the general principles of water resources management related to rural areas were extracted from global guidelines. In the next step, through library studies and questionnaires, the key stakeholders of water resources management in the study area were identified and the factor burden of each was determined, the highest factor weight belongs to the Ministry of Energy and rural water and sewage companies (16.50), followed by the General Department of Environmental Protection (15.30) and finally, local and rural communities have the lowest weight (10.43). Most of the rural wastewater in Dena protected area belongs to agricultural wastewater (53%), followed by domestic wastewater (28%) and finally, industrial wastewater (11%). The results of the good fit evaluation of the model show that GFI is equal to 0.977 and considering that it is more than 0.9, so it is acceptable in the region. Finally, the proposed model was designed to prepare a plan to assess the effects of rural wastewater on biodiversity in the region in 5 steps, which were: Investigation of wastewater management background; Study of biodiversity indicators; Investigating the characteristics of wastewater in rural communities; Determining the effects and consequences of lack of proper wastewater management in rural communities; Providing appropriate, applicable and scientific methods for wastewater management in rural communities.
