Global water resources are severely affected by the changing climate threatening water security goals. However, our understanding of the impact of key interventions, particularly in coastal zones and certain types of terrestrial water projects, is limited. This review aims to systematically assess the effectiveness of coastal and terrestrial water-sector interventions at different scales in developing countries.
Interventions—projects, programmes, or policies—that aim to enhance adaptive capacity and mitigation co-benefits in the coastal and terrestrial water sectors are critical to achieving water security. Therefore, identifying relevant coastal and terrestrial water-sector interventions and analysing their impacts will help developing countries achieve climate targets. This review is addressing this evidence gap and is consider the implications for GCF and climate programming.
