Sustainable cities and human settlements

This chapter supports SDGs 3, 11, and 16 by exploring ways of improving shelter provision for refugees through better coordination of humanitarian agencies, the development of minimum standards, and enhanced self-help housing strategies.
Urban forests are integral components of urban ecosystems, which could generate significant ecosystem services, such as offsetting carbon emission, removing air pollutants, regulating the microclimate, and recreation. These ecosystem services contribute to improving environmental quality, quality of life, and sustainable urban development. Despite a long history of inserting vegetation in human settlements in China, modern scientific study of this natural-cum-cultural resource did not start until the 1990s.
