[G]roundwater is a limited resource that is subject to over-exploitation, as well as pollution from various practices relating to sanitation, waste management, and use of external inputs in land use for agriculture. Further, there are often direct linkages between quality of groundwater and wetlands and coastal resources. Groundwater resources are also sensitive to climate change, biodiversity loss, and land management.
This Report indicates that these relationships are more evident and direct, that they have clearer and shorter feedback loops, and that they take on even more significance and urgency, in the context of Small Island Developing States (SIDS). Moreover, it is apparent from much of the literature relating to SIDS that the sustained development of these countries depends heavily on the protection of ecosystem services, and on integrated management of their freshwater resources.
