Because it sustains all living organisms, is needed for drinking, cooking, cleaning, sanitation, and our bodies are about 60–70% water.

Drinking, cooking, and cleaning/sanitation.

About 60–70%.

Agriculture depends heavily on irrigation to grow crops.

For manufacturing and cooling; also for cleaning or as a raw material in some products.

Fisheries need healthy water bodies for aquatic life, and hydropower requires flowing water to generate electricity.

They provide habitats and resources that sustain diverse plants and animals.

By driving the water cycle and aiding nutrient flow in ecosystems.

A situation where usable water is insufficient due to factors like over-exploitation, pollution, uneven distribution, population growth, or urbanization.

Using more water than can be naturally replenished; for example, excessive irrigation in agriculture.

Industrial waste, sewage, and chemicals contaminate water, making it unsafe and reducing the usable supply.

Because some areas receive ample rainfall and river flow while others remain dry, leading to regional shortages.

More people require more drinking water, food production, and domestic use.

Expanding cities increase water demand for housing, infrastructure, and industries, and reduce open spaces that store rainwater.

To prevent future scarcity and to maintain ecological balance.

It ensures adequate water in rivers, wetlands, and aquifers to support plants, animals, and natural processes.

By meeting needs through efficient use and local management, reducing the necessity for expensive centralized infrastructure.

It improves resilience to irregular rainfall, floods, and droughts.

Providing clean water to more people, including those in rural and remote areas, through conservation and management.

Agriculture, industries, and fisheries.
