World Wildlife Fund report on free flowing rivers

The report Connected and Flowing: a renewable future for rivers, the climate and people argues that, today, countries can power their growth with grids that are low carbon, low cost, and low impact on people and nature. Along with supporting the richest freshwater biodiversity, healthy free-flowing rivers deliver a number of critical ecosystem services. They support freshwater fish stocks that improve food security for hundreds of millions of people, deliver sediment that keeps deltas above rising seas, provide nutrients to fertilise floodplain fields and support coastal fisheries, and mitigate the impact of extreme floods, storms and droughts.
