تغییر اقلیم و احیای اراضی کشاورزی رها شده و کم بازده، مبتنی بر رویکرد آبخیزداری

Climate change effects on the hydrological system of the basin by changing amount of precipitation and temperature and, because of the interaction among systems, it would influence the environmental, economic, and social systems. The intensity of these unfavorable effects could be different given that vulnerability of the systems. Also, climate change affects agricultural production and, consequently, agricultural factors such as food security and economic well-being. One of the specific effects of climate change and its consequences is the reduction of river water resources and the gradual abandonment of agricultural lands. Therefore, the current research was carried out in the Kolahjoob watershed in the Markazi province to restore such lands through water extraction methods. Based on watershed management activities such as terracing and creation of earthen dams, while controlling flood and erosion in the region, water supply for agricultural activities was made and 10 hectares of abandoned agricultural lands were revived and turned into gardens as a model. Therefore, one of the achievements of this project is, on the one hand, controlling and managing floods and sediments and reducing the action of the bed and waterway, on the other hand, attracting social participation, revitalizing abandoned lands, modifying the cultivation pattern, and improving production and employment of residents. Therefore, planning in the form of watershed unit and comprehensive management of watersheds is a clear path for the revival of the farmer and consequently food security and social welfare.
