The knowledge gap.

Despite their importance, lakes remain among the least monitored water bodies on Earth . Unlike rivers, which often have established gauging stations, lakes are poorly studied, particularly in low- and middle-income countries. UNEP is working to change this. Through tools and initiatives such as the Freshwater Ecosystems Explorer , the UNEP lakes portal , the United Nations Decade on Ecosystem Restoration and integrated water resources management frameworks, efforts are underway to close data gaps and improve policies, plans and approaches. But we need to scale up, and scale up fast. UNEP launched a landmark, transboundary initiative in the Lake Tanganyika Basin that works across Burundi, Democratic Republic of Congo, Tanzania and Zambia to protect biodiversity, restore critical wetlands and degraded landscapes, support sustainable fisheries management and enhance water security . It will rehabilitate 1,700 hectares of ecosystems and foster catchment-wide governance through commun...

Why we need to protect, conserve and restore lakes?

Across the world, lakes fed by rivers, glacial melt, groundwater, rain and snow have played an important role in human civilization, culture and development. They contain most of the liquid fresh water on the planet’s surface , house an array of wildlife, and make farming, fishing and industry possible. They also play an important role in water storage, aquifer recharge and air temperature regulation. Yet, due to climate change, pollution, mining, population pressure, and unsustainable use, they are declining at an unprecedented rate. Freshwater ecosystems have lost more extent and biodiversity than almost any ecosystem in the world. The planet’s more than 3 million lakes vary enormously in terms of their salinity and chemical composition, area, depth, biodiversity, the volume of water they store, their ownership (whether publicly or privately owned), the extent to which they are polluted, the rate at which they are shrinking, and more. Lake Baikal in Russia is estimated to contai...
