For people and nature, water is life.
But the planet’s freshwater systems are crashing. Globally, monitored freshwater species populations have declined by an average of 83% since 1970. We’ve lost 64% of the world’s wetlands since 1900, and just 37% of the world’s longest rivers remain unimpeded and free flowing.
Whether through drought or flooding, climate change is often most visibly expressed through water, and these impacts are only expected to increase in the years to come.

With water at the heart of the climate and biodiversity crises, safeguarding the world’s fresh water—its rivers, wetlands, groundwater and ecosystems—is core to our 2030 Goals.

Fresh Water on the Global Stage
Fresh water is at the top of the global agenda this month as the United Nations holds its first water conference in more than 40 years.
From March 22 to 24, leaders from around the world will gather in New York for the UN 2023 Water Conference—formally known as the “2023 Conference for the Midterm Comprehensive Review of Implementation of the UN Decade for Action on Water and Sanitation (2018-2028).”
Why Is the UN Water Conference Important?
In the 40-plus years since the UN's last water conference, the global water crisis has accelerated significantly and the need for global action has become more urgent than ever.
The UN 2023 Water Conference comes on the heels of COP27 (UN Climate Conference) and COP15 (UN Biodiversity Conference), both of which saw meaningful progress made on water issues. Leaders from around the world will seek to build on this momentum and set the tone for global water action from now to 2030 and beyond.
Why Is TNC at the UN Water Conference?
TNC is focused on elevating nature’s role in addressing the diverse water challenges countries around the world are facing. We’re heartened by the progress made at both COP27 and COP15, but we know there is much more to do. TNC stands ready to help countries around the world realize their bold ambitions.
How Is TNC Stepping Up for Fresh Water?
In addition to advocating for nature as a key pathway for addressing the global water crisis, TNC is doubling down on its commitment to freshwater conservation around the world. By 2030, TNC aims to conserve 1 million kilometers of rivers and 30 million hectares of lakes and wetlands to benefit tens of millions of people. To deliver on this commitment, we will invest $250 million over the next seven years in partnership with the public and private sector through projects around the world.
Dive Deeper into TNC’s Commitment to Fresh Water
TNC’s commitment to freshwater conservation dates back to our earliest days as an organization. In fact, our first ever conservation project was to establish New York’s Mianus Gorge Preserve, which helps protect the Mianus River and now spans more than 900 acres. Today our freshwater portfolio is more than 450 projects strong and touches nearly every region of the world.
