Realizing sustainable development on the ground is not possible without strong buy-in and leadership from local governments, such as district and municipal authorities, that provide essential public services. To ensure the reliability and sustainability of these services, local governments must commit human, financial and material resources over the long term to upgrading and maintaining underlying infrastructure, such as roads, water and sanitation, energy grids or waste management facilities. The growing number of risks and challenges stemming from urbanization, climate change, public health crises and advances in digital technology make the case for effective asset management as compelling as ever. This project focused on strengthening the capacity of local government officials in select LDCs in Africa and Asia to manage infrastructure assets more effectively and sustainably. Over 90 per cent of training participants reported increased knowledge of local infrastructure asset management in post workshop surveys. Significant progress was made in strengthening the national policy, regulatory and institutional environments for asset management with three out of four beneficiary countries in the process of developing, reviewing and adopting national asset management policies that will provide clear guidance to both national agencies and local governments on more inclusive, resilient and sustainable infrastructure asset management. In addition, the project was successful in leveraging additional resources within the UN system, as well as from multilateral donors, and extending diagnostic assessments and training provided to additional municipalities beyond those originally foreseen. Following strong demand, the training curriculum and good practices on asset management that came out of the project were captured in the UN Handbook, Managing infrastructure assets for sustainable development: A handbook for local and national governments. The Handbook was launched in early 2021 through a series of regional interactive online solutions dialogues, with a strong focus on asset management basics, data and crisis resilience, and has been translated into 10 different languages, including all six official UN languages. The online solutions dialogues trained over 2,400 local and central government officials from developing countries. In one of the project’s beneficiary countries the largest national university recently launched a new master’s degree programme on infrastructure asset management based on the UN Handbook imparting its tools and insights on sustainable infrastructure asset management to new generations of public sector officials. The project also led to collaboration with UNITAR and Columbia University on a Massive Open Online Course (MOOC) that covers the entire handbook and gives local and central governments around the world access to comprehensive and self-paced training on a wide range of infrastructure asset management tools and techniques in support of sustainable development. The MOOC, for which over 1000 students have signed up thus far, provides a significant opportunity to increase scale and long-term sustainability of the UN work on Infrastructure Asset Management.
