The RC system's coordination infrastructure advanced on multiple fronts. All UNCTs produced results reports, with 79% of host governments affirming their effectiveness in demonstrating country-level impact. Progress on common premises, common back offices, and business operations strategies continued, with 57% of UN personnel now accommodated in common premises. Independent evaluations and OIOS triennial reviews consistently corroborated RC system performance, with implementation of audit and evaluation recommendations reaching 83% in 2025. Surge coordination support was deployed in 14 RCOS while peace and development advisers and human rights advisers advanced prevention, governance, and rights-based approaches across complex settings - even as funding cuts significantly reduced their deployment. Against a backdrop of escalating demand, contracting development assistance, and shifting UN country presences, the RC system has embarked on a structured recalibration, informed by Member State and RC consultations and independent evaluations, including by UNDS entities. Four priorities shaped the process: completing the unfinished business of UNDS reform under General Assembly resolution 72/279; strengthening RC leadership and core RCO functions in support of evolving needs; tailoring capacities to country contexts, with particular attention to SIDS, LDCs, LLDCS, and crisis settings; and equipping UNCTs with future-ready capabilities in data, digital solutions, and innovation.
