Dr. Sergio Macedo Gomes de Mattos, who works for the Brazilian Artisanal Fishing Network (Teia de Redes da Pesca Artesanal do Brasil), was a contributing author to the marine part of the IHH Brazil case study. Mattos has worked in small-scale fisheries for 30 years and is interested in the implementation of fisheries policies and undertaking research into fisheries bio-economics, stock assessment and transdisciplinary approaches to achieving sustainable small-scale fisheries. We spoke with him about how he believes the IHH method and findings will have an impact in Brazil.
