Small islands can guide visualization of the diverse information requirements of future context-relevant coastal governance. On small marine islands (<20 000 km2), negative effects of coastal challenges (e.g., related to population growth, unsustainable resource use or climate change) can develop rapidly, with high intensity and extreme impacts.

The coastal communities of Louisiana are highly vulnerable to coastal change, and the potential benefits of protecting, restoring, and enhancing intact ecosystems are particularly important. However, there is a current lack of synthesized information on potential benefits of ecosystem-based restoration options at a parish, basin, or coastwide scale.

The coastal communities of Louisiana are highly vulnerable to coastal change, yet the population has remained steady in the midst of highly dynamic environmental, social, and economic conditions. Adaptations in the form of social networks, mobility, and ingenuity have enabled Louisiana’s coastal communities to remain viable, although changed over time. Much of Louisiana’s coastal zone is outside of the current system of hard infrastructure (primarily levee) protection.

Anthropogenic nitrogen contributes to water quality degradation, but it is difficult to distinguish sources once they are mixed in coastal ecosystems. Natural abundances of stable nitrogen isotopes (delta N-15) were measured in oyster (Crassostrea virginica) tissues (muscle, gills, and mantle) during summer 2006 to summer 2008 to identify nitrogen sources in Monie Bay (a subestuary of Chesapeake Bay) receiving freshwater inputs from three tributary creeks. The creeks (estimated flushing times:

The narrow coastal area of Lami Town, Fiji, is surrounded by steep hills with three rivers flowing to the ocean, making it highly susceptible to flooding and erosion. This technical report provides greater detail of the cost-benefit assessment of four adaptation scenarios to reduce Lami Town's vulnerability to flooding and erosion, both of which are projected to increase due to climate change.

Climate change is predicted to have a range of impacts on Pacific Island ecosystems and the services they provide for current and future development. There are a number of characteristics that can make adaptation approaches that utilise the benefits of ecosystems a compelling and viable alternative to other adaptation approaches.

Long-term non-linear ecosystem-scale changes in water quality and biotic communities in coastal lagoons have been associated with intensification of anthropogenic pressures. In light of incipient changes in Johnson Bay (an embayment of Chincoteague Bay, Maryland-Virginia, USA), examination of nitrogen sources was conducted through synoptic water quality monitoring, stable nitrogen isotope signatures (deltaN-15) of in situ bioindicators, and denitrification estimates.

To achieve desired environmental outcomes, environmental condition and trends need to be rigorously measured and communicated to resource managers, scientists, and a broader general audience. However, there is often a disconnect between responsive ecosystem monitoring and decision making for strategic long-term management. This project demonstrates how historical monitoring data can be synthesized and used for future planning and decision making, thereby closing the management feedback cycle.

On Assateague Island, an undeveloped barrier island along Maryland and Virginia, a foredune was constructed to protect the island from the erosion and breaching threat caused by permanent jetties built to maintain Ocean City Inlet. Scientists and engineers integrated expertise in vegetation, wildlife, geomorphology, and coastal engineering in order to design a habitat restoration project that would be evaluated in terms of coastal processes rather than static features.
