Rivers are critically important for several key reasons: they provide essential resources such as food, fresh water, power, transportation, and sanitation; they support rich and diverse ecosystems; and they play a vital role in human culture and livelihoods. Nearly 90% of the earth’s population lives near river systems. Rivers house about 50% of all fish species and support wetlands that provide homes for around 40% of the world’s species. They irrigate 62% of all irrigated land, which accounts for 40% of global food production, supporting approximately a quarter of the world’s food supply. Additionally, rivers sustain fisheries that supply primary protein sources and livelihoods for millions of people. Beyond ecology, rivers provide hydroelectric power, transportation routes, flood protection, and recreational opportunities. They have also shaped human history by enabling the rise of great civilizations and cities. Protecting rivers is essential due to their multifaceted roles in sustaining both nature and human societies.
