ESCAP in Brief presents a concise, illustrated overview of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP)—its remit, structure, and programmes as of 1979. It introduces ESCAP as the UN’s regional arm for Asia and the Pacific, serving more than half of the world’s population and addressing shared development challenges across a vast geography from Iran to the Cook Islands. The brochure outlines ESCAP’s three-level operating model (regional, subregional, and country) and its role as a technical forum and clearing-house for information rather than a source of capital, while highlighting priority themes of the era such as integrated rural development, technology transfer, trade facilitation, transport connectivity (highways, railways, ports), telecommunications, population and social development, and cooperation mechanisms (e.g., Mekong, CCOP/SOPAC, Typhoon frameworks). It explains governance through the Commission and legislative committees, notes the Secretariat’s day-to-day functions and inter-agency coordination, and documents milestones including the shift from ECAFE to ESCAP and the Bangkok headquarters. Appendices list members and associate members. Overall, the report serves as a snapshot of ESCAP’s mandate, machinery, and cooperative instruments in support of equitable development across the region
