Sustainable Development Goal 6 commits the world to ensuring that everyone has access to safe water by 2030, and includes targets on protecting the natural environment and reducing pollution. This World Water Day, the theme of which is ‘Nature for Water’, WorldFish and the International Water Management Institute (IWMI), key partners in the CGIAR Research Program on Fish Agri-Food Systems (FISH), reflect on how improved dam operation and reservoir management can, in some circumstances, mitigate the often negative impacts of large dams on natural fish stocks.
Exact numbers are hard to come by but, globally, inland freshwater fisheries are vital for the livelihoods of tens, if not hundreds, of millions of people. Fisheries play a crucial role in eliminating hunger, promoting health and reducing poverty. Fish are extremely nutritious and the primary source of protein and essential nutrients for many of the poorest people in the world.
