The 2024 edition of the United Nations World Water Development Report highlights how developing and maintaining water security and equitable access to water services is essential to ensuring peace and prosperity for all. However, water resources are distributed unevenly across the globe, with significant disparities in availability. Approximately, 70% of the Earth’s surface is covered by water, yet only about 2.5% is freshwater, and even less is readily accessible for human use. Of this freshwater, around 68.7% is locked in glaciers and ice caps, while only 0.3% exists in easily accessible surface water bodies like lakes and rivers.

The 2024 edition of the United Nations World Water Development Report highlights how developing and maintaining water security and equitable access to water services is essential to ensuring peace and prosperity for all. However, water resources are distributed unevenly across the globe, with significant disparities in availability. Approximately, 70% of the Earth’s surface is covered by water, yet only about 2.5% is freshwater, and even less is readily accessible for human use. Of this freshwater, around 68.7% is locked in glaciers and ice caps, while only 0.3% exists in easily accessible surface water bodies like lakes and rivers.
