Drought is defined as a continuous period of dry weather that can vary in length between countries. It can be caused by seasonal changes in weather patterns like the Hadley cell and Inter-Tropical Convergence Zone, leading to wet and dry seasons in some regions. Long term droughts over multiple years can have disastrous consequences, affecting both human and natural systems. The consequences of drought include food shortages and the need for food aid when rains fail. Various groups like nomadic pastoralists have adapted to seasonal droughts, while long term management strategies are needed to address extended drought crises.
