Global Water Challenges and Solutions Through Watershed Management

The video discusses global water scarcity, highlighting Iran's severe water crisis due to groundwater depletion. It introduces watershed management as a crucial method for managing water resources, explaining its role in preventing floods and droughts. The video also covers challenges in watershed management, such as international collaboration and land development impacts. Strategies for effective management are discussed, including sewage planning and wildlife restoration. A successful case study from Wankoot, India, demonstrates practical watershed management solutions.
