This Special Issue presents five reviews of global evidence on topics relevant to climate action in developing countries. The SI presents one standalone evidence gap map on results-based payments and three systematic reviews on: transformational change, coastal and terrestrial water sector interventions, and behavioural science. We also present a realist review on just transition. Each review is accompanied by a companion protocol or approach paper. At a time of declining levels of international aid, the crux of the current climate challenge is to put into play incentives and mechanisms to frontload investments into interventions proven to work across contexts. These five reviews offer trusted evidence for policymakers to consider when setting policy and allocating scarce resources.
