How To Combat Post-Natural Disaster Related Environmental Gentrification And Environmental Inequality Accelerated By Climate Change, Marielle Christie Mar 2019

How To Combat Post-Natural Disaster Related Environmental Gentrification And Environmental Inequality Accelerated By Climate Change, Marielle Christie

Honors Theses

This thesis aims to illustrate the concept of natural disaster-induced environmental gentrification. There is a heightened vulnerability to unmitigated forced displacement by socioeconomically disadvantaged residents following a natural disaster. Environmental gentrification is a variant of green gentrification. Green gentrification occurs when providing green amenities to a city increases local property values and attracts wealthier residents to a previously polluted or disenfranchised neighborhood, which displaces the low-income residents. Similarly, environmental gentrification is a process that occurs after a natural disaster and rapidly accelerates the process of traditional urban gentrification or green gentrification. As a result, environmental gentrification magnifies and facilitates further ...


Back To The Future: Conserving Functional And Phylogenetic Diversity In The Amphibian-Climate Refuges, Ricardo Lourenço-De-Moraes, Felipe S. Campos, Rodrigo B. Ferreira, Mirco Solé, Karen H. Beard, Rogério P. Bastos Jan 2019

Back To The Future: Conserving Functional And Phylogenetic Diversity In The Amphibian-Climate Refuges, Ricardo Lourenço-De-Moraes, Felipe S. Campos, Rodrigo B. Ferreira, Mirco Solé, Karen H. Beard, Rogério P. Bastos

Ecology Center Publications

Climate refuges have been used by several species over historical climate change. Ectothermic species often display good models for climate change studies because they are highly sensitive to temperature. Analysis of species loss with ecosystem and evolutionary values helps to understand environmental processes and climate change consequences. We determined the functional and phylogenetic diversity of amphibians in the Atlantic Forest hotspot, using multiple models representing present and future conditions. Through a novel approach, we predict species’ threat status by 2080, following the IUCN’s criterion B1. Our results estimate a drastic reduction in species richness, ecosystem functioning and evolutionary history ...


Climate Change Adaptation In The Delta Nile Region Of Egypt: Implications For Agricultural Extension, Hazem S. Kassem, Abdel Raouf Suleiman Bello, Bader M. Alotaibi, Fahd O. Aldosri, Gary S. Straquadine Jan 2019

Climate Change Adaptation In The Delta Nile Region Of Egypt: Implications For Agricultural Extension, Hazem S. Kassem, Abdel Raouf Suleiman Bello, Bader M. Alotaibi, Fahd O. Aldosri, Gary S. Straquadine

Extension Research

This study used quantitative and qualitative methods to collect data, using questionnaires and interviews, from 792 randomly-selected farmers in two of the governorates in the Nile Delta Region, Egypt. A workshop was organized for 59 extension professionals working in the two governorates, looking at how the adaptive capacity of the agricultural sector towards climate change was being guided by policy-makers. Two focus groups were used: one with senior officials from the regional governorates and the other with central government administrators from the Ministry of Agriculture and Land Reclamation. The study findings suggested that 51.9% of the investigated farmers at ...


Assessment Of The Effects Of Climate Change On Evapotranspiration With An Improved Elasticity Method In A Nonhumid Area, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu Dec 2018

Assessment Of The Effects Of Climate Change On Evapotranspiration With An Improved Elasticity Method In A Nonhumid Area, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu

Watershed Sciences Faculty Publications

Climatic elasticity is a crucial metric to assess the hydrological influence of climate change. Based on the Budyko equation, this study performed an analytical derivation of the climatic elasticity of evapotranspiration (ET). With this derived elasticity, it is possible to quantitatively separate the impacts of precipitation, air temperature, net radiation, relative humidity, and wind speed on ET in a watershed. This method was applied in the Wuding River Watershed (WRW), located in the center of the Yellow River Watershed of China. The estimated rate of change in ET caused by climatic variables is −10.69 mm/decade, which is close ...


Quantifying The Impact Of Climate Change And Human Activities On Streamflow In A Semi-Arid Watershed With The Budyko Equation Incorporating Dynamic Vegetation Information, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu Dec 2018

Quantifying The Impact Of Climate Change And Human Activities On Streamflow In A Semi-Arid Watershed With The Budyko Equation Incorporating Dynamic Vegetation Information, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu

Watershed Sciences Faculty Publications

Understanding hydrological responses to climate change and land use and land cover change (LULCC) is important for water resource planning and management, especially for water-limited areas. The annual streamflow of the Wuding River Watershed (WRW), the largest sediment source of the Yellow River in China, has decreased significantly over the past 50 years at a rate of 5.2 mm/decade. Using the Budyko equation, this study investigated this decrease with the contributions from climate change and LULCC caused by human activities, which have intensified since 1999 due to China’s Grain for Green Project (GFGP). The Budyko parameter that ...


Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy Aug 2018

Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration projects from ...


Forecasting Climate Change Impacts On Plant Populations Over Large Spatial Extent, Andrew T. Tredennick, Mevin B. Hooten, Cameron L. Aldridge, Collin G. Homer, Andrew R. Kleinhesselink, Peter B. Adler Jul 2016

Forecasting Climate Change Impacts On Plant Populations Over Large Spatial Extent, Andrew T. Tredennick, Mevin B. Hooten, Cameron L. Aldridge, Collin G. Homer, Andrew R. Kleinhesselink, Peter B. Adler

Wildland Resources Faculty Publications

Plant population models are powerful tools for predicting climate change impacts in one location, but are difficult to apply at landscape scales. We overcome this limitation by taking advantage of two recent advances: remotely sensed, species-specific estimates of plant cover and statistical models developed for spatiotemporal dynamics of animal populations. Using computationally efficient model reparameterizations, we fit a spatiotemporal population model to a 28-year time series of sagebrush (Artemisia spp.) percent cover over a 2.5 × 5 km landscape in southwestern Wyoming while formally accounting for spatial autocorrelation. We include interannual variation in precipitation and temperature as covariates in the ...


Aiding Decision Making To Reduce The Impacts Of Climate Change, Howard Kunreuther Sep 2014

Aiding Decision Making To Reduce The Impacts Of Climate Change, Howard Kunreuther

Operations, Information and Decisions Papers

Utilizing theory and empirical insights from psychology and behavioural economics, this paper examines individuals’ cognitive and motivational barriers to adopting climate change adaptation and mitigation measures that increase consumer welfare. We explore various strategies that take into account the simplified decision-making processes used by individuals and resulting biases. We make these points by working through two examples: (1) investments in energy efficiency products and new technology and (2) adaptation measures to reduce property damage from future floods and hurricanes. In both cases there is a reluctance to undertake these measures due to high and certain upfront costs, delayed and probabilistic ...


Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill May 2013

Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill

All Graduate Theses and Dissertations

Stream temperature (ST) is a primary determinant of individual stream species distributions and community composition. Moreover, thermal modifications associated with urbanization, agriculture, reservoirs, and climate change can significantly alter stream ecosystem structure and function. Despite its importance, we lack ST measurements for the vast majority of USA streams. To effectively manage these important systems, we need to understand how STs vary geographically, what the natural (reference) thermal condition of altered streams was, and how STs will respond to climate change. Empirical ST models, if calibrated with physically meaningful predictors, could provide this information. My dissertation objectives were to: (1) develop ...


London Free Press And Sun Media: Reader Beware Of Bias., Richard B. Philp Dec 2011

London Free Press And Sun Media: Reader Beware Of Bias., Richard B. Philp

Richard B. Philp

Recent articles in the London Free Press, a Sun Media publication, have attempted to discredit environmentalists concerned about climate change and the environmental impact of the Alberta tar sands. Articles by authors with right wing leanings (but not so identified) have appeared in the news pages rather than in the editorial pages where they belong.These have promoted the tar sands and their related pipelines, suggested an American conspiracy to influence public opinion by funding Canadian environmental groups and attempted to resurrect the so-called e-mail scandal from climate scientists. The present paper offers a rebuttal to these claims with supporting ...
