Asia-Pacific small island developing states (SIDS) have a limited evidence-base for informed and integrated sustainable development policy making. Integrated sustainable development requires valuation of the economic, environmental and social dimensions of development so that the true costs and benefits of macro-economic decision making can be captured. This has been a key principle of sustainable development since the 1992 Earth Summit and remains a high priority in the Outcome of Rio+20 and in Pacific regional preparations for the 3rd Global Conference on Small Islands Developing States. Strengthening the evidence-base and the enabling environment for sustainable development planning and implementation is a key component of effective governance in SIDS. The value of the economic contribution of the environment and social equity underpins the capacity of policy makers (particularly those in Ministries of Finance and Planning) to make balanced policy choices in pursuit of sustainable development. More balanced policy choices will allow enablers to be put in place to move away from the current excessive priority attached to achieving nominal targets (such as a single digit inflation rate, a primary budget surplus or a specific public debt-to GDP ratio). A shift to focus on the quality of growth in its three dimensions-economic, social and environmental-is critical. This project, to be implemented by ESCAP with support from DESA and UNEP and in collaboration with UN Women, focuses on integrating two aspects of sustainable development into macro-economic policy making: economic valuation of the environment and gender inequality. As critical aspects of the social and environmental pillars of sustainable development, valuation of natural capital and gender inequality will illustrate the value of internalizing and balancing environmental and social considerations in decision making for sustainable development. Directly responding to requests by member States in the Rio+20 outcome document for support for balanced integration of the three pillars of sustainable development, the project seeks to build an evidence base for integrated sustainable development by piloting the overall approach, identifying lessons throughout and sharing these at a high-level meeting and knowledge management platform. The target group is national planning and finance entities and the national statistical systems (including focal points in social and environment departments/ministries) in Pacific SIDS (Pacific member States with the inclusion of Timor Leste and the Maldives in regional fora).
