This report is designed for those working in the fields of water resources management and natural resources conservation who want to consider new patterns of source water protection in light of ongoing climate change.

Nature-based solutions (NBS) have the potential to address pressing engineering needs while restoring natural landscapes.

This report uses rigorous hydrodynamic and economic models to value the coastal flood protection services of mangroves globally, and identifies the places where mangroves provide the greatest risk reduction benefits to people and property.

Wastewater is a resource that is too valuable to throw away, especially in an increasingly water-scarce world. Wastewater from large cities is often pumped directly into rivers or seas without treatment, leading to pollution and posing a threat to the health of ecosystems and people.

Planting trees is a cost-effective way to tackle urban air pollution, which is a growing problem for many cities. A study by US-based The Nature Conservancy (TNC) reported that the average reduction of particulate matter near a tree was between 7% and 24%.

The Atlas of Ocean Wealth is the largest collection to date of information about the economic, social and cultural values of coastal and marine habitats from all over the world. It is a synthesis of innovative science, led by The Nature Conservancy (TNC), with many partners around the world.

The Nature Conservancy’s white paper, “The Power of Rivers: Finding balance between energy and conservation in hydropower development,” addresses the global expansion of hydropower dams and the need to find development scenarios that provide energy, but also work for communities and nature.

The Urban Water Blueprint analyzes the state of water in more than 2,000 watersheds and 530 cities worldwide to provide science-based recommendations for natural infrastructure enhancements that can be integrated alongside traditional engineered solutions to improve water quality.

The approach to determine national baselines for measuring reduced emissions from deforestation and degradation (REDD) has emerged as central to negotiations over a REDD mechanism in a post- Kyoto policy framework. The baseline approach is critical
