Automated Cropping Intensity Extraction From Isolines Of Wavelet Spectra, Bingwen Qiu, Zhuangzhuang Wang, Zhenghong Tang, Chongcheng Chen, Zhanling Fan, Weijiao Li

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Timely and accurate monitoring of cropping intensity (CI) is essential to help us understand changes in food production. This paper aims to develop an automatic Cropping Intensity extraction method based on the Isolines of Wavelet Spectra (CIIWS) with consideration of intra- class variability. The CIIWS method involves the following procedures: (1) characterizing vegetation dynamics from time–frequency dimensions through a continuous wavelet transform performed on vegetation index temporal profiles; (2) deriving three main features, the skeleton width, maximum number of strong brightness centers and the intersection of their scale intervals, through computing a series of wavelet isolines from the wavelet ...

A Multi-Scale Spatiotemporal Modeling Approach To Explore Vegetation Dynamics Patterns Under Global Climate Change, Bingwen Qiu, Zhuangzhuang Wang, Zhenghong Tang, Zhe Liu, Difei Lu, Chongcheng Chen, Nan Chen

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Given the complexity of vegetation dynamic patterns under global climate change, multi-scale spatiotemporal explicit models are necessary in order to account for environmental heterogeneity. However, there is no efficient time-series tool to extract, reconstruct and analyze the multi-scale vegetation dynamic patterns under global climate change. To fill this gap, a Multi-Scale Spatio-Temporal Modeling (MSSTM) framework which can incorporate the pixel, scale, and time-specific heterogeneity was proposed. The MSSTM method was defined on proper time-series models for multitemporal components through wavelet transforms. The proposed MSSTM approach was applied to a subtropical mountainous and hilly agro-forestry ecosystem in southeast China using the ...


Accounting For The Short Term Substitution Effects Of Walking And Cycling In Sustainable Transportation, Daniel P. Piatkowski, Kevin J. Krizek, Susan L. Handy Jan 2015

Accounting For The Short Term Substitution Effects Of Walking And Cycling In Sustainable Transportation, Daniel P. Piatkowski, Kevin J. Krizek, Susan L. Handy

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The environmental benefits of bicycling and walking depend on the degree to which their use substitutes for car driving. Assuming that every walking and bicycling trip replaces a driving trip is likely to produce overestimates of the potential for such modes to reduce vehicle travel and city-scale greenhouse gas emissions. Measuring this ‘‘substitution effect’’ is not straightforward. There are many dimensions of the substitution effect, including trip type, substituting mode, extent, time horizon, and activity patterns. Previously used approaches to measure substitution include indirect inference and direct questioning. This study piloted an intercept survey using the direct questioning approach at ...

Developing A Drought Planning Evaluation System In The United States, Mark D. Svoboda, Zhenghong Tang

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Drought is a normal part of the climate cycle, affecting every climate regime on the planet. Drought indicates a special period in which an unusual moisture scarcity causes a serious hydrological imbalance. Drought is related to the timing and effectiveness of the rains, high temperature, high wind, and low humidity. The typical impacts of drought may include dry lands, low or empty water-supply reservoirs, low groundwater levels (dried up wells), crop damage, and ensuing environmental degradation. In the United States, drought accounts for losses in the billions of dollars. In fact, a FEMA (1995) report estimates the average annual losses ...

Moving From Agenda To Action: Evaluating Local Climate Change Action Plans, Zhenghong Tang, Samuel D. Brody, Courtney E. Quinn, Liang Chang, Ting Wei

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Climate change is conventionally recognized as a large-scale issue resolved through regional or national policy initiatives. However, little research has been done to directly evaluate local climate change action plans. This study examines 40 recently adopted local climate change action plans in the US and analyzes how well they recognize the concepts of climate change and prepare for climate change mitigation and adaptation. The results indicate that local climate change action plans have a high level of “awareness”, moderate “analysis capabilities” for climate change, and relatively limited “action approaches” for climate change mitigation. The study also identifies specific factors influencing ...

Mitigating Greenhouse Gas Emissions Through Local Land Use Planning, Zhenghong Tang, Christopher Hussey

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Land use and land use planning have profound implications for greenhouse gas emission (GHG). Local land use planning is well suited to play a critical leadership role in addressing the effects of climate change by encouraging change in development patterns to reduce GHG emissions and their impacts. Although some studies have begun to discuss the role of local land use planning in climate change, little research has been conducted to determine how to convert the concepts of climate change into local land use planning tools and empirically integrate climate change mitigation and adaptation strategies into local land use planning. The ...

Measuring Tsunami Planning Capacity On U.S. Pacific Coast, Zhenghong Tang, Michael K. Lindell, Carla S. Prater, Samuel D. Brody

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Abstract: The U.S. Pacific coastal states are at risk from both locally and distantly generated tsunamis. This vulnerability can be reduced by effective hazard management plans, but no studies have been conducted to determine how local jurisdictions have incorporated tsunami hazard management into their planning frameworks. This paper analyzes the quality of hazard management plans from 43 coastal counties in these states. Plan quality was measured by a plan evaluation protocol defined by five components and 37 indicators. The results show that few Pacific coastal counties have prepared well for tsunamis. Most plans have a weak factual basis, unclear ...

Evaluating California Local Land Use Plan’S Environmental Impact Reports, Zhenghong Tang, Elise Bright, Samuel Brody

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Local land use planning has profound impacts on environmental quality; however, few empirical studies have been conducted to systematically measure local land use plans’ environmental assessment quality and to identify the factors influencing it. This paper analyzes the quality of 40 Environmental Impact Reports (EIRs) of local jurisdictions’ land use plans in California. A plan evaluation protocol defined by five core components and sixty-three indicators is developed to measure the quality of local land use plans’ EIRs. The descriptive results indicate that the local jurisdictions produce relatively good quality on its EIRs, but there is still much room for improvement ...


Linking Planning Theories With Factors Influencing Local Environmental-Plan Quality, Zhenghong Tang Jan 2008

Linking Planning Theories With Factors Influencing Local Environmental-Plan Quality, Zhenghong Tang

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The major planning theories provide a theoretical foundation for environmental planning. This study extends the major planning theories and develops a robust conceptual framework to measure the key factors influencing local environmental-plan quality. A random sample of forty Californian local comprehensive land-use plans and associated planning processes is analyzed to identify the critical factors influencing environmental-plan quality. Results from multiple regression analysis indicate that regular updating, environmental-information management and sharing, and planners contribute significantly to local environmental-plan quality. The findings expand established planning theories and practice by suggesting ways to improve local environmental-plan quality.

Demographic Characteristics And Concerns Of New Arrivals To Rural Nebraska, James Potter, Rodrigo Cantarero, Nicholas Pischel

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Immigration is often thought of as a problem primarily for large metropolitan areas. However, much of the recent literature dealing with the meat processing industry focuses on the migration it generates towards small, rural towns in the American Midwest. The prior studies frequently use a qualitative method. The primary goal of this study was to explore the characteristics of new arrivals to two Midwestern towns (Schuyler and Crete, Nebraska). The basic method used for developing the inventory of demographic characteristics and concerns was analyzing data from two quantitative studies previously conducted by the authors. Identical questions were selected from each ...

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Recent interest in expanding offshore oil production within waters of the United States has been met with opposition by groups concerned with recreational, environmental, and aesthetic values associated with the coastal zone. Although the proposition of new oil platforms off the coast has generated conflict over how coastal resources should be utilized, little research has been conducted on where these user conflicts might be most intense and which sites might be most suitable for locating oil production facilities in light of the multiple, and often times, competing interests. In this article, we develop a multiple-criteria spatial decision support tool that ...
