Q16.Why is the world today confronted with a crisis of availability of and access to freshwater resources?

The global freshwater crisis stems from a severe imbalance between increasing demand and diminishing supply, exacerbated by various anthropogenic and environmental pressures, threatening human well-being and sustainable development.

• Climate Change: Alters hydrological cycles, causing extreme weather, glacier melt, and increased evaporation, reducing natural replenishment.
• Population Growth & Urbanization: Drives exponential demand for domestic, agricultural, and industrial uses, concentrating stress on urban systems.
• Pollution: Contaminates surface and groundwater from industrial effluents, agricultural runoff, and untreated sewage, rendering water unusable.
• Over-extraction & Unsustainable Practices: Depletes groundwater aquifers and surface water bodies due to inefficient irrigation and withdrawal rates exceeding recharge.
• Inadequate Infrastructure & Governance: Manifests as poor water management policies, leaky distribution systems, and insufficient investment, hindering equitable access.
• Economic Disparities & Geopolitical Issues: Creates unequal resource distribution, limits infrastructure in poorer regions, and fuels transboundary water disputes.

Addressing this complex crisis necessitates integrated water resource management, technological innovation, equitable distribution policies, and international cooperation for water security.
