Freshwater resources refer to water that is naturally occurring in rivers, lakes, and underground aquifers, which is essential for drinking, agriculture, and industry. Unlike saltwater found in oceans, freshwater has a low concentration of salts, making it suitable for human consumption and irrigation. These resources are limited, as only about 2.5% of the Earth's water is freshwater, with a significant portion trapped in glaciers and ice caps. Sustainable management of freshwater resources is crucial to ensure availability for future generations and to support ecosystems that rely on this vital resource.
