The NACOMA project aims to enhance coastal and marine biodiversity conservation through the mainstreaming of biodiversity conservation and sustainable use into coastal policy, a legislative framework, and institutional and technical capacity, and by supporting targeted investments for biodiversity conservation in critical ecosystems on the coast. The sustainability of this is threatened by poor planning, where allocation of sites is environmentally and economically suboptimal, and by open access, which encourages overuse, pollution and damage. There are carrying capacity constraints in the case of recreational angling tourism, and some specific tour operator activities such as dolphin watching.
