Large-scale water-related projects are a model global environmental issue. From dams controlling and rerouting water flow to providing access to clean drinking water and monitoring the nutrient quality of water resources, local, national, and international players often have to work together to manage these water resources. A new study of nearly 200 major international water-related projects over the past 20 years has identified existing and emerging challenges and how science can offer solutions. The report claims that 'insufficient and disjointed management of human demands on water and aquatic systems has led to situations where both social and ecological systems are in jeopardy and have even collapsed.'
