Since the first studies began in the Alvor Estuary, A ROCHA always made sure that their results and conclusions were communicated in order to make this scientific knowledge of the area more accessible. This has also been a tool that proved crucial in the conservation and management of species and habitats, and we want to develop it further in the near future.

At the beginning, our publications were available as brochures and observation reports, but more recently we have been publishing several articles in indexed journals, as well as papers for conferences and seminars, as you can see below.
