The first working paper is prepared under the ESCAP?IsDB project “Improving Connectivity in North and Central Asia through Co-Deployment of ICT, Energy and Transport Infrastructures”. Entitled “In-depth study on the co-deployment of ICT infrastructure with transport and energy infrastructure in Uzbekistan”, it explores how Uzbekistan can accelerate nationwide digital connectivity through smarter, integrated infrastructure planning. Within the Asia-Pacific Information Superhighway (APIS) Action Plan 2022?2026, ESCAP and APIS Working Group 1, co-chaired by Uzbekistan, advance the Connectivity for All pillar, with co-deployment of ICT, transport and energy infrastructure as a key strategy. Building on ESCAP’s prototype Infrastructure Corridors Simulator and the Infrastructure Co-Deployment Partnership Portal, piloted in Kazakhstan, Kyrgyzstan and Mongolia, the Technical Infrastructure Co-Deployment Expert Group (TICEG, 2024-2025) analysed Uzbekistan’s infrastructure, prioritised routes and identified four potential co-deployment projects along the Kyzylorda Uchkuduk, Akhangaran Tukimachi Syrdarya, Navoi Bukhara and Yangi Angren Namangan Margilon Lochin corridors. Part 1 of the study presents this in-depth analysis and corridor prioritisation and recommends upgrading the Simulator into a fully fledged Geo-Infrastructure Simulator (GInSi) to support systematic, evidence-based corridor planning that quantifies cost savings, socio-economic gains, environmental and climate co-benefits, investment attractiveness and long-term multiplier effects, thereby strengthening coordinated infrastructure planning and advancing digital connectivity for all.
