Biodiversity is gaining more and more importance on the international scene. In the era of climate change and sustainable development this is a central theme. The sustainable exploitation of biodiversity allows the development of communities in a balanced way based on diverse resources and activities, making them more resilient to adverse impacts of both economic and climatic origin.

This volume of the RILP magazine celebrates biological diversity in the CPLP space and, at the same time, is an alert for the need to invest in its study and conservation. The articles now assembled, and the curriculum of their authors, prove that there are Portuguese-speaking competences for this existential task. And the planet Earth, and the vastness of its occupants, thank you for all the attention you can give. We intend to give an overview of what is done in Portuguese-speaking countries in terms of biodiversity studies. We are driven on a trip that begins in the Cufada lagoons in Guinea-Bissau, alternating between Angola and Timor-Leste, passing through Brazil and Portugal, to end in the sea of ​​Mozambique.
