"The causes of inadequate housing in the Asia-Pacific region can be grouped under three broad headings. Under the heading social, economic and political factors are such issues as poverty and economic development, discrimination, war and violence, and the effects of disasters. Government behaviour and ideas, both past and present, influence the housing policy environment. Current policy debates center on decentralisation, corruption and regulatory frameworks, as well the role of the rental sector and attitudes towards eviction."
