Several suggestion related to further research and development of urban renewal that we could identiry are:
strengthening the roles of government (particularly in developing countries) to prevent government land from squatters, otherwise urban renewal for those areas would have high social cost.
Research on property development needs to be developed in relation to financial enggineering which is very potential and significant for urban areas in developing countries
Research on the intensity of buildings associated with the capacity of roads is important to prevent over capacity of roads or over intensity of built-up areas
research on local wisdom is also important to provide basic approach for socialization of urban renewal in ‘urban villages’. Particularly related to hazards mitigation (floods and the like).
