UN-Habitat's vision of "a better quality of life for all in an urbanizing world" is bold and ambitious. The agency works with partners to build inclusive, safe, resilient and sustainable cities and communities. UN Volunteers Mercy Ochieng Odhiambo and Shiho Jinno are helping communities in Kenya overcome the waste management crisis. Their focus is particularly on the impoverished in urban centres, who are directly affected when waste is discarded and burnt on city streets. Not only does this lead to air pollution, disease and health issues; it also increases poverty and inequality.
