RCA assesses its socio-economic impact from 2000 to 2023, informing stakeholders and the public. The Regional Cooperative Agreement for Research, Development, and Training Related to Nuclear Science and Technology for Asia and the Pacific (RCA) was established in 1972 and has since benefited from the IAEA Technical Cooperation (TC) programme. Highlighting the socio-economic impact of the RCA in the region is crucial. Therefore, National RCA Representatives have endorsed an initiative to conduct a social and economic impact assessment of the RCA programme supported under the IAEA TC programme from 2000 to 2023. The results of these assessments will be published and disseminated to RCA State Parties, relevant stakeholders, and the public. This report is one of the planned four reports in the areas of air quality monitoring, food safety, groundwater and nuclear medicine.
