- Anthropogenic, direct pressures on coastal wetlandsPublication . Newton, Alice; Icely, John; Cristina, Sónia; Perillo, Gerardo M. E.; Turner, R. Eugene; Ashan, Dewan; Cragg, Simon; Luo, Yongming; Tu, Chen; Li, Yuan; Zhang, Haibo; Ramesh, Ramachandran; Forbes, Donald L.; Solidoro, Cosimo; Béjaoui, Béchir; Gao, Shu; Pastres, Roberto; Kelsey, Heath; Taillie, Dylan; Nhan, Nguyen; Brito, Ana C.; de Lima, Ricardo; Kuenzer, ClaudiaCoastal wetlands, such as saltmarshes and mangroves that fringe transitional waters, deliver important ecosystem services that support human development. Coastal wetlands are complex social-ecological systems that occur at all latitudes, from polar regions to the tropics. This overview covers wetlands in five continents. The wetlands are of varying size, catchment size, human population and stages of economic development. Economic sectors and activities in and around the coastal wetlands and their catchments exert multiple, direct pressures.
- Assessing, quantifying and valuing the ecosystem services of coastal lagoonsPublication .

Coastal lagoons are shallow semi-enclosed systems that support important habitats such as wetlands, mangroves, salt-marshes and seagrass meadows, as well as a rich biodiversity. Coastal lagoons are also complex social-ecological systems with ecosystem services that provide livelihoods, wellbeing and welfare to humans. This study assessed, quantified and valued the ecosystem services of 32 coastal lagoons. The main findings of the study are: (i) the definitions of ecosystem services are still not generally accepted; (ii) the quantification of ecosystem services is made in many different ways, using different units; (iii) the evaluation in monetary terms of some ecosystem service is problematic, often relying on non-monetary evaluation methods; (iv) when ecosystem services are valued in monetary terms, this may represent very different human benefits; and, (v) different aspects of climate change, including increasing temperature, sea-level rise and changes in rainfall patterns threaten the valuable ecosystem services of coastal lagoons.
