Rapid Review of Water Knowledge for Pacific Small Islands Developing States


The objective of this report is to provide an overview of current knowledge related to the water sector across Small Island Developing States (SIDS) of the Pacific region. SIDS face a specific set of water, sanitation, and hygiene (WASH) challenges related to the extreme fragility of their water resources to anthropogenic impacts and climate change, the unique features of their water cycles, lack of scale, and isolation. Many of the modern water management paradigms applied elsewhere need careful reconsideration in that context.

The first section of the report provides a summary of findings in terms of key knowledge areas and gaps and proposes recommendations for future analytical work in the water sector in the Pacific. The following sections provide a more detailed review of current knowledge across seven key challenges identified as particularly critical in Pacific SIDS context: (i) environmental variability and change; (ii) sociocultural aspects; (iii) isolation and small scale; (iv) uncontrolled urbanization; (v) service delivery models; (vi) sector coordination, integration, and capacity; and (vii) data, information, and knowledge. Each topic is covered by a dedicated section describing the nature of the challenge, the identified ways forward, and knowledge gaps.
