In search of nexus triple wins: planning for and evidence of economic transformation, social inclusion and ecological sustainability in Sri Lanka, Thailand and the Dominican Republic

Achieving prosperity for all within planetary boundaries requires that governments take wide-ranging transformative action, but achieving ‘triple-wins’ by joining up policies across economic, social and environmental realms can be challenging. A companion analysis undertaken under the ODI Nexus project (Diwakar, 2022) analysed key indicators in these realms in lower income countries and identified the Dominican Republic, Sri Lanka and Thailand as front-runners in achieving more holistic development outcomes. Looking deeper at these case studies, we sought to identify national policy interventions that struck a balance between the different realms of development and explored the policy development, legislation and implementation processes required for integrated transformational policy to succeed. In each we found national-scale, triple-win policies led from the president’s or prime minister’s office. These policies can usually be traced to specific political moments that forced a reckoning with the failures of previous development policy, often resulting in radical change of direction in development planning. Yet, despite the existence of triple-win policies, as of 2019, there was limited evidence of triple-win outcomes being achieved. Instead, the case study countries typically performed well in one or two realms, often to the detriment of progress in the other(s). We present potential reasons for the lacklustre impact of these policies and conclude with suggestions for future work to outline where in the policy landscape it may be possible to enact transformational nexus policies and how to support them to achieve their outcomes in the timeframes required to ensure equitable prosperity within planetary boundaries.
