Abstract(s)
This study provides an overview of 11 lagoons in North Africa, from the Atlantic to
the Eastern Mediterranean. Lagoons are complex, transitional, coastal zones providing
valuable ecosystem services that contribute to the welfare of the human population. The
main economic sectors in the lagoons included fishing, shellfish harvesting, and salt and
sand extraction, as well as maritime transport. Economic sectors in the areas around the
lagoons and in the watershed included agriculture, tourism, recreation, industrial, and
urban development. Changes were also identified in land use from reclamation, changes
in hydrology, changes in sedimentology from damming, inlet modifications, and coastal
engineering. The human activities in and around the lagoons exert multiple pressures
on these ecosystems and result in changes in the environment, affecting salinity,
dissolved oxygen, and erosion; changes in the ecology, such as loss of biodiversity;
and changes in the delivery of valuable ecosystem services. Loss of ecosystem services
such as coastal protection and seafood affect human populations that live around the
lagoons and depend on them for their livelihood. Adaptive management frameworks for
social–ecological systems provide options that support decision makers with sciencebased
knowledge to deliver sustainable development for ecosystems. The framework
used to support the decision makers for environmental management of these 11
lagoons is Drivers–Activities–Pressures–State Change–Impact (on Welfare)–Responses
(as Measures).
