There is often a large gap between stated commitments to sustainable development, as reflected in documents such as National Sustainable Development Strategies (NSDS) and their implementation in different sectors. This project aims to address two aspects of the challenging problem of implementation, by helping selected target countries (1) to develop participatory, multi-stakeholder processes, and (2) to support implementation of sustainable development in different sectors. It will build on the leadership and convening authority of ministries of planning and finance, and other key central government agencies. Under (1), it will assist countries to design effective multi-stakeholder processes, to benefit from the contextual and technical knowledge of different partners such as non-government organizations, academia and the private sector that can inform, and can actively lead, different aspects of NSDS implementation. Under (2), it will work to integrate sustainable development goals and targets in key sectoral strategies and programmes, and will initiate a programme to train sectoral ministry staff in sustainable development issues. The project will build on projects carried out under the Development Account’s 8th (1213D) and 9th (1415I) tranches, has selected to work in many of the same countries to continue support in working towards long-term results, and would apply outcomes of previous projects such as a toolbox of capacity development materials developed under project 1415I and a knowledge management platform developed under project 1213D, while under this 10th tranche project, engaging a wider range of partners and sectors in each target country. The project will also enhance and use the national and regional level partnerships developed in the preceding projects.
