World Water Day

Most of Earth's freshwater is locked in glaciers and ice caps. Only about 1% of the total freshwater is liquid and accessible for human use in rivers, lakes, and groundwater.

Water is a fundamental resource used across all these sectors, from basic human survival to industrial production and leisure.

Fossil fuel combustion releases greenhouse gases, leading to global warming. These higher temperatures increase evaporation rates and alter precipitation patterns, significantly disrupting the water cycle.

Trees release water vapor into the atmosphere through transpiration. When forests are cleared, this moisture contribution decreases, leading to reduced cloud formation and rainfall in the region.

Scientific estimates generally attribute approximately 10% of the moisture in the atmosphere to plant transpiration, with the remainder coming primarily from evaporation from oceans and other water bodies.

Transpiration is the specific biological process by which plants absorb water through roots and release it as vapor through their leaves.

Studies, including those by the Ramsar Convention, estimate that approximately 64 to 71 percent of the world's natural wetlands have been lost since 1900 due to human development and land use changes.

According to UN Water reports, approximately 80 percent of global wastewater is discharged back into the environment without adequate treatment, causing significant pollution.

Forests act as natural filters and sponges. Replenishing them improves soil structure, which increases water infiltration and helps recharge groundwater supplies.

Green infrastructure refers to natural or semi-natural systems that provide environmental services, such as water management, similar to traditional man-made (grey) infrastructure.

Nature-based solutions involve using natural processes to manage resources. Electricity lines are man-made, industrial infrastructure, not a nature-based solution.

The 2018 World Water Day campaign was officially titled 'Nature for Water', focusing on exploring nature-based solutions to the water challenges of the 21st century.

The United Nations 2030 Agenda for Sustainable Development sets the target year 2030 for achieving universal access to safe and affordable drinking water.

Access to clean water is essential for hygiene, health, and development. Living without it leads to poor health and education outcomes, not good health.

Climate change and environmental degradation are primary drivers of the current global water crisis, affecting water availability, quality, and distribution.

According to the WHO and UNICEF, approximately 2.1 billion people globally lack access to safely managed drinking water services at home.

The water cycle (or hydrologic cycle) describes the continuous movement of water on, above, and below the surface of the Earth.

World Water Day is an annual United Nations observance held on March 22 to advocate for the sustainable management of freshwater resources.
