How CIMPACT-DST Has Been Applied

CIMPACT-DST is helping planners in Vietnam develop safer, more resilient communities and infrastructure. The tool was first used locally in Thua Thien Hue Province, where it has informed the development of four climate-resilient urban master plans, before being expanded to the national level.

The national version of CIMPACT-DST is now fully owned by the Vietnam Institute for Urban Planning (VIUP), which also hosts the maps on its server. Users can now download the Vietnamese tool version directly from VIUP's website. As of June 2015, the national tool has been applied to review major economic plans for the Northern, Central, Southern, and Mekong economic regions, as well as zoning plans for Go Gang Island, Long Son Island, and Nui Lon – Nui Nho, and detailed planning in the central highlands area of Lam Dong province. Cascadia and VIUP also trained staff in six additional provinces and developed a sustainability plan to ensure that VIUP staff can continue to update and maintain the tool independently after the USAID project ends in June 2015.

Information on application of CIMPACT-DST to date is provided in the sections below.

Revision of Regional Economic Plans

VIUP applied Vietnam CIMPACT-DST to review plans for four major economic regions in Vietnam: Northern, Central, Southern, and Mekong Delta. VIUP planners used CIMPACT-DST's sea level rise inundation maps and climate projections to identify cities and key infrastructure (e.g., national roads, regional water supply plants) under potential risk, and planners adjusted the plans to minimize identified risks, where possible. Tool users at VIUP also considered CIMPACT-DST’s list of recommended adaptation measures in adjusting and implementing the four major economic region plans, as well as other urban plans for the region. For example, VIUP planners learned that part of national roads in Kien Giang and Ca Mau would likely be affected by sea level rise. Thus, they included these following adaptation measures from the tool output in revised plans:

    Consider revising construction ground levels to account for       projected sea level rise
    - Consider adding sea dyke capacities to new coastal road         construction where coastal flooding may be an issue
    - Design and build drainage systems to accommodate                                                                                                                     stormwater runoff from impervious surfaces

Coastal Planning in Thua Thien Hue Province

Since being transferred to the Hue Planning Institute (HPI) in August 2013, CIMPACT-DST has since been used to inform the development of four new climate-resilient urban master plans for Thua Thien-Hue province in Vietnam: 

    - Vinh Thanh Commune Master Plan, Phu Vang District
    - Vinh Hien Commune Master Plan, Phu Loc District
    - Dien Loc Commune Master Plan, Phong Dien District
    - Phong An Commune Master Plan, Phong Dien District

HPI planners integrated several new resilience features into these plans, including softer infrastructure along coastlines and conservation of natural floodplain areas (see figure below for a description of planning adjustments). Together, these four climate-resilient master plans will reduce the vulnerability of tens of thousands of residents by 2030.

Flood Research and Plan Adjustment in An Van Duong

In 2015, the Hue Planning Institute (HPI) aplied CIMPACT-DST to a project supported by ISET to research the causes of worsening flooding in several suburban areas in An Van Duong, near Hue. HPI staff used the tool to supplement other information sources. They plan to present the resulting research to local government staff and encourage them to make specific adjustments to increase flood resilience.

Planning in Lam Dong Province

Lam Dong Department of Construction and Lam Dong Construction Consulting Joint Stock Company applied CIMPACT-DST to the Phi Lieng Commune center detailed plan in Dam Rong District, Lam Dong Province.  Planners sought to maintain and utilize natural environmental conditions and services, such as topography, forestry, and water bodies, in plan development.

The tool informed planners of various projected climate impacts in the project area, and encouraged them to consider the following adaptive measures:

    - Planting pine trees on the hill slope near the high school to reduce landslide risk
    - Expanding public parks and green space along stream banks to minimize flooding risk of urban areas during the rainy season
