The 2018 Revision of World Urbanization Prospects produced by the Population Division of the UN Department of Economic and Social Affairs (UN DESA) notes that globally, the urban population in the mid-year of 2020 was 4.4 billion (56% of the world's population). As the urban population continues to grow, urban environmental issues such as air pollution, weather, climate, and water-related hazards become dominant.
The development of an integrated urban service is to address multiple challenges, including those related to disaster risk reduction (DRR) with a focus on the high-impact weather in the context of dense population and, to deal with those challenges, the government needs to mobilize efforts, creativity, and innovation from all sectors to achieve sustainable development of urbanized regions.
