Governments in the Mesoamerican Reef region are exploring the use of nature-based solutions to strengthen coral health and societal benefits for coastal communities. A new study led by Stanford researchers in collaboration with scientists from the World Wildlife Fund, the Healthy Reefs Initiative, and others from the Smart Coasts project quantified the outcomes of different watershed interventions to support coral health at regional versus national scales, and identified target areas that could improve both ecosystem and societal benefits nationally and across the region.
