Remediation in Phnom Penh, Cambodia : landscape strategies and collaboration

Abstract

This research project investigates and proposes strategies for the remediation of a brownfield site in Phnom Penh, Cambodia. The overarching strategy is collaboration, phased over time, between the Government, developers and the community to deliver environmental, economic and social benefits. A variety of landscape mitigation techniques have been explored and proposed to help achieve these outcomes. A key aspect is the premise that greenery and water can act as catalysts to boost environmental remediation, social inclusion and real estate value.

The site, which is located in a southwestern suburb of Phnom Penh, is comprised of three distinct zones: a disused landfill, polluted lake, and a partly occupied plot between them. The phased aspect of the project includes a range of programmes which ebb and flow between the zones for an anticipated period of 15 to 20 years.

On-site observation, techniques learnt from relevant precedents/theories and social considerations were used as groundwork to identify, develop and refine strategies. These strategies carry the hope of finally addressing the social/ environmental/ developmental problems in Phnom Penh – there is a potential to raise public awareness regarding the ramifications of current developmental patterns whilst showcasing a viable and responsible alternative.
