High quality statistics and integrated information are important inputs into evidence based policy and decision-making. They are also key to monitoring internationally agreed goals, sustainable development, and the post-2015 development agenda. Given the critical role of high quality environment statistics, and their integration with socio-economic statistics the overall objective is to strengthen national capacities of developing countries for the sustained, regular production of a priority set of environmental statistics, environmental-economic accounts, and the resulting indicators, in order to measure progress towards sustainable development. The project is composed of two complementary modules, developed in a harmonized manner.Module A will work with countries that are in the early stages of developing environment statistics. It will be executed through a set of activities including organizing an initial sub-regional capacity-building workshop to train the countries using the FDES and the Basic Set of Environment Statistics, applying the Environment Statistics Self-Assessment Tool, developing national work plans, providing technical assistance and organizing national workshops for the participating countries, promoting inter-institutional platforms and data-sharing protocols at the national level, and organizing a closing sub-regional workshop to share progress, lessons learned and discuss the way forward. Module B will work with countries that expressed interest in implementing the SEEA. It will be executed through a set of activities including developing diagnostic tools for the self-assessment on institutional environment and data availability for compiling environmental-economic accounts, organizing two expert group meetings to discuss diagnostic tools and compilation guidelines, organizing four sub-regional workshops to build capacity in countries and develop national strategies, developing regional implementation strategies for environmental-economic accounting, organizing four pilot projects, and developing compilation guidelines.
