Due to its geographic location, the coastal area of Guinea-Bissau remains remarkably enriched with biodiversity and relatively abundant natural resources. These resources play a vital role in ensuring food security and producing economic benefits for the local population. In order to preserve the biodiversity, the Government of Guinea-Bissau created a system of protected areas, covering 12% of its territory. Unfortunately, the institution responsible for the management of these protected areas, the Institute of Biodiversity and Protected areas, faces difficulties ensuring effective monitoring of these protected areas. This project aims to strengthen the management and create effective monitoring of 3 marine protected areas in Guinea-Bissau.
