Dr. Cheng is dedicated in bringing theory and practice in resilient and sustainable development. Her research interests include climate justice, water resources management, scenario planning, green infrastructure planning and design, sustainability and climate change. She received her Ph.D. degree in Regional Planning at the Department of Landscape Architecture and Regional Planning in the University of Massachusetts. She obtained her Master in Landscape Architecture at the University of Michigan and a B.S. in Horticulture with a submajor in landscape architecture from the National Taiwan University. She worked as a professional landscape architect in Chicago, IL, and Tampa, FL, areas. She is a registered Practice Landscape Architect and LEED Accredited Professional. During her professional career, she was involved in several watershed and stormwater management planning projects as well as on-site stormwater management design, including a Illinois Chapter American Society of Landscape Architects Honor Award winning project for Kishwaukee watershed land use and transportation plan in Illinois.

Through a series of assumptions varied by MAPC community types—Inner Core, Regional Centers, Maturing Suburbs and Developing Suburbs—we converted projected population into housing demands on developable lands with different housing density allowance for estimating land use change in each community. Then we applied Social Vulnerability Index (SoVI) and long-term flooding hazards (HI) with land use and climate change input via SWAT (Soil and Water Assessment Tool) (Arnold and Allen 1996) hydrological modeling and GIS spatial analyses. The results revealed that Current Trends consumed more agricultural and forest lands and resulted in greater flooding hazards among growth scenarios; however the variance is not significant due to most development occurred through infill and only 1% of land changed through greenfill. Flooding risks were shown at a greater variance among climate change impact scenarios suggesting that stream flow is more sensitive to climate than land use change in this watershed. Moreover, Current Trends placed more people within higher flooding hazards areas resulting higher flooding risks. This paper concluded that growth management plays an important role in preserving open space and allocating population to areas less impacted by climate-induced environmental hazards and social vulnerability and in turn enhance community resilience.
The results indicate the importance of the values from the public in the development of sustainable land use plans. The DABC framework and quantitative modelling using STELLA helps to illustrate the trade-offs and prioritization of attributes under different scenarios of development patterns and landscape changes. Each landscape outcome under different scenarios has dynamic impacts on ABC resources and overall sustainability of the community. In summary, the DABC framework is useful in incorporating (1) collective and dynamic interaction among ABC components and consequent effects on the overall sustainability index, and (2) prioritization of policy attributes in decision making through public participation and adaptation to changes in planning environment and scenarios. The dynamic and adaptive modelling can be used as an effective tool in evaluating and developing land use plans by the public, interdisciplinary stake holders and planners through assessing ecological and social resources of various planning and policy scenarios aimed toward sustainability.
