Drought

The video tutorial explains droughts, which are prolonged periods without rain causing issues for nature and humans. It covers three types of droughts: meteorological, hydrological, and agricultural. Meteorological drought occurs with less rainfall than usual, hydrological drought involves low groundwater and stream flow, and agricultural drought affects crop survival. Each type of drought has distinct causes and impacts, affecting ecosystems and human activities differently.
