  Abstract = {Mangroves are critical nursery habitats for fish and invertebrates, providing livelihoods for many coastal communities.

We address these gaps by developing a global model of mangrove associated fisher numbers and mangrove fishing intensity.

By projecting this conceptual model using geospatial datasets, we were able to estimate the number and distribution of mangrove associated fishers and the intensity of fishing in mangroves. We estimate there are 4.1 million mangrove associated fishers globally, with the highest number of mangrove fishers found in Indonesia, India, Bangladesh, Myanmar, and Brazil. Mangrove fishing intensity was greatest throughout Asia, and to a lesser extent West and Central Africa, and Central and South America.},
