This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is tightly linked with urbanization. Urban development with increasing greenhouse gas emission worsens climate change, while climate change in turn influence hydroclimate and ecosystem functions, and indirectly affect urban systems. The Intermountain West is experiencing rapid urban growth, climate change interacting with urbanization poses new challenges to the Intermountain West. Urban planning needs to adapt to these new changes and constrains, and to develop new tools and plans to effectively respond to climate changes. An urban growth model SLEUTH is applied to predict the future urban growth and land use dynamics in the Intermountain west, using Cache County as a case study. Through the creation of scenarios, model outputs provide best estimates of future land use dynamics and urban growth under different policy and management conditions related to climate change scenarios. The success of integrating climate change into urban planning model opened up the opportunities for planners and decisions makers to foresee the potential consequences brought by individual policy or management, and to better address climate change issues in the 0́−transitional0́+ urban environment.

Book Synopsis Land-Use and Land-Cover Changes by : Nicole Mölders
Download or read book Land-Use and Land-Cover Changes written by Nicole Mölders and published by Springer Science & Business Media. This book was released on 2011-09-15 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildfires, changing glaciers, deforestation, open-pit mining, increasing demands for food and bio-fuel production and the growth of megacities change our landscape. The book comprehensively reviews the current knowledge on how natural and anthropogenic land-use/cover changes affect weather, air quality and climate worldwide and explains how these changes may trigger further land-use/cover changes. It discusses how anthropogenic land-use/cover changes have affected local and regional climate and air quality since the settlement of America and the industrialisation. It addresses the topic how long-range transport of pollutants and dust of devasted areas as well as teleconnections may cause changes far away from the areas where the land-use/cover changes occurred, for which land-use/cover change may become an international issue similar to CO2. It also discusses relations to global change and future societal and scientific challenges related to land-use/cover changes.

Download or read book Global Environmental Change and Land Use written by Han Haarman and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between environmental change and human activities is com plex, requiring the concepts and tools of a number of disciplines for its effective analysis. Land-use and land-cover change has only recently become a topic susceptible to scientific research, as these concepts and tools have been devel oped and made available. Rooted in a broad community concemed with global change, systematic research has begun into land-use systems at different scales and interactions, and their links with global cyc1es of water, nitrogen and carbon are being explored. Partly based on research initiated by the Dutch National Research Programme on Global Air PolIution and Climate Change (NRP), this book touches upon various land-use and land-cover issues in relation to global environmental change. In addition to the biogeochemical cyc1es, land as a car rier for functions of economic activities, food and fibre production and energy production via biomass are discussed. Crucial in studying land use is human behaviour and man-environment interaction at different scales. Land-use and land-cover change is an important contrlbutor of greenhouse gasses as these activities directly interfere with the carbon, nitrogen and water cyc1es. These cyc1es are connected through numerous feedback loops. The interface of land-use and c1imate is essentially determined by the interaction of man and the environment. Man uses land primarily to produce food; a relatively small area is needed for urban development.
Book Synopsis Relationships Between Runoff, Land Cover and Climate in the Semi-arid Intermountain Region of the Western U.S.A. by : Ibrahim Nourein Mohammed
Download or read book Relationships Between Runoff, Land Cover and Climate in the Semi-arid Intermountain Region of the Western U.S.A. written by Ibrahim Nourein Mohammed and published by . This book was released on 2012 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: PUBLIC ABSTRACT: Hydrologic science is broadly defined as the geoscience that describes and predicts the occurrence, circulation and distribution of the water of the earth and its atmosphere. The need to predict the effects of land cover and climate changes with their associated impacts on hydrology are among the pressing areas of research, especially within the western United States. The main objective of this dissertation is to provide a better knowledge of land use or land cover along with climate change impacts on streamflow generated from watersheds in the semi-arid intermountain region in and around Utah. This objective was addressed using analyses of historical observations, as well as statistical and physically based computer models. The results show trends in streamflow and other associated climate quantities in the Utah watersheds studied. The dissertation also presents a quantification of the sensitivity of streamflow to changes in land cover related to watershed management. The Great Salt Lake, a closed basin lake that receives inputs from its surrounding watershed, has a level that fluctuates in response to streamflow and other inputs. A model for fluctuations in Great Salt Lake volume and level was used to quantify the sensitivity of these fluctuations to changes in streamflow inputs, and climate conditions over the lake that drive evaporation from the lake.

Book excerpt: This book compiles available knowledge of the response of mountain ecosystems to recent climate and land use change and intends to bridge the gap between science, policy and the community concerned. The chapters present key concepts, major drivers and key processes of mountain response, providing transdisciplinary orientation to mountain studies incorporating experiences of academics, community leaders and policy-makers from developed and less developed countries. The book chapters are arranged in two sections. The first section concerns the response processes of mountain environments to climate change. This section addresses climate change itself (past, current and future changes of temperature and precipitation) and its impacts on the cryosphere, hydrosphere, biosphere, and human-environment systems. The second section focuses on the response processes of mountain environments to land use/land cover change. The case studies address effects of changing agriculture and pastoralism, forest/water resources management and urbanization processes, landscape management, and biodiversity conservation. The book is designed as an interdisciplinary publication which critically evaluates developments in mountains of the world with contributions from both social and natural sciences.
Book Synopsis Impacts of Land Use and Land Cover Change on Urban Hydroclimate of Colorado River Basin by : Ruby Upreti
Download or read book Impacts of Land Use and Land Cover Change on Urban Hydroclimate of Colorado River Basin written by Ruby Upreti and published by . This book was released on 2017 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid urbanization and population growth occurring in the cities of southwestern United States have led to significant modifications in its environment at local and regional scales. Both local and regional climate changes are expected to have massive impacts on the hydrology of Colorado River Basin (CRB), thereby accentuating the need of study of hydro-climatic impacts on water resource management in this region. This thesis is devoted to understanding the impact of land use and land cover (LULC) changes on the local and regional hydroclimate, with the goal to address urban planning issues and provide guidance for sustainable development. In this study, three densely populated urban areas, viz. Phoenix, Las Vegas and Denver in the CRB are selected to capture the various dimensions of the impacts of land use changes on the regional hydroclimate in the entire CRB. Weather Research and Forecast (WRF) model, incorporating the latest urban modeling system, is adopted for regional climate modeling. Two major types of urban LULC changes are studied in this thesis: (1) incorporation of urban trees with their radiative cooling effect, tested in Phoenix metropolitan, and (2) projected urban expansion in 2100 obtained from Integrated Climate and Land Use Scenarios (ICLUS) developed by the US Environmental Protection Agency for all three cities. The results demonstrated prominent nocturnal cooling effect of due to radiative shading effect of the urban trees for Phoenix reducing urban surface and air temperature by about 2~9°C and 1~5°C respectively and increasing relative humidity by 10~20% during an mean diurnal cycle. The simulations of urban growth in CRB demonstrated nocturnal warming of about 0.36°C, 1.07°C, and 0.94°C 2m-air temperature and comparatively insignificant change in daytime temperature, with the thermal environment of Denver being the most sensitive the urban growth. The urban hydroclimatic study carried out in the thesis ssists in identifying both context specific and generalizable relationships, patterns among the cities, and is expected to facilitate urban planning and management in local (cities) and regional scales.

Download or read book The Effects of Climate Change and Urbanization on the Runoff of the Rock Creek Basin written by and published by . This book was released on 2008 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate changes brought on by global warming are expected to have a significant affect on the Pacific Northwest hydrology during the 21st Century. Current research anticipates higher mean annual temperatures and an intensification of the hydrological cycle. This is of particular concern for highly urbanized basins, which are considered more vulnerable to changes in climate. Because the majority of previous studies have addressed the influences of either climate or urban land cover changes on runoff, there is a lack of research investigating the combined effect of these factors. The Rock Creek basin (RCB), located in the Portland, OR, metropolitan area, has been experiencing rapid urban growth throughout the last 30 years, making it an ideal study area for assessing the affect of climate and land cover changes on runoff. Methods for this assessment include using a combination of climate change and land cover change scenarios for 2040 with the semi distributed AVSWAT-X (Arc View Soil and Water Assessment Tool) hydrological model to determine changes in mean runoff depths at the monthly, seasonal, and annual scales. Statistically downscaled climate change results from the ECHAM5 general circulation model (GCM) found that the region would experience an increase of 1.2°C in the average annual temperature and a 6% increase in average annual precipitation between 2030 and 2059. The model results revealed an amplification of runoff from either climate or urbanization. Projected climate change plus low-density, sprawled urban development for 2040 produced the greatest change to mean annual runoff depth (+5.5%), while climate change plus higher-density urban development for 2040 resulted in the smallest change (+5.3%), when compared to the climate and land cover of 2001. The results of this study support the hypothesis that the combination of both climate change and urbanization would amplify the runoff from the RCB during the 21st Century. This has significant implications for water resource managers attempting to implement adaptive water resource policies to future changes resulting from climate and urbanization.
Book Synopsis The Effects of Land Cover/land Use Change on Ecosystem Functions in Semi-arid Inner Mongolia by : Ranjeet John
Download or read book The Effects of Land Cover/land Use Change on Ecosystem Functions in Semi-arid Inner Mongolia written by Ranjeet John and published by . This book was released on 2011 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land cover change in semi-arid areas, in the context of climate change, can significantly affect the carbon sequestration potential in these fragile ecosystems. Semi-arid Inner Mongolia, P.R.C, is experiencing climate change with associated land cover/use change that includes an increase in irrigated agriculture and population growth. Land cover change was monitored at the regional level through the use of MODIS derived remote sensing products along with meteorological and carbon exchange data obtained from five EC flux towers across a variety of ecosystem types that include natural and disturbed grassland, shrublands as well as land use types such as croplands and dune stabilizing poplar stands. Firstly, I quantified the land cover/use change at the regional and biome levels in the context of landscape fragmentation and the possible consequences. Secondly, I used flux data to validate intra-annual dynamics of satellite derived GPP in different ecosystem types using existing GPP models. In addition I developed and validated a new model, the modified vegetation photosynthesis model. Finally, I derived predictive models of plant species diversity, developed specifically for semi-arid grasslands which used improved vegetation and water indices. The major finding of this study were: (1) increasing portions of dominant grassland shrubland and barren cover within the decade points toward a water stressed landscape that is becoming more homogenous and is corroborated by a decrease in proportions of rare cover types. The rapid increase in socio-economic growth leading to a growing population base is described by increasing cohesion and aggregation of urban/built-up patches as well as an increasing number of patches and interspersion of cropland land use. (2) variance in GPP and water content indices were the two most important variables for predicting species richness in Inner Mongolia, while MODIS-derived vegetation and water content indices were selected as significant independent variables for specific biome type. The predictive power of models improved greatly when the region was stratified by biome and life-form type and especially when the anthropogenically modified cover types such as croplands were excluded from the model. (3) The intrannual dynamics of satellite derived GPP vegetation photosynthesis model (VPM) and modified VPM (MVPM) models were validated by flux towers at five ecosystem types across semi-arid Inner Mongolia. Though not as computationally intensive like most process-based models, MVPM offers an advantage over VPM by being independent of any ground measured meteorological data. MVPM provides a cost effective method of predicting GPP, especially at remote study sites which lack the required infrastructure to set up EC flux towers. While there was reasonable agreement between the observed GPPtower and predicted GPPVPM and GPPMVPM indicating the potential of these models for modeling of GPP in semi-arid ecosystems, there was some uncertainty in the predictive ability of these models, attributed to different sources of error.

Download or read book Climate Change and Land Use/Cover Change Impacts on Watershed Hydrology, Nutrient Dynamics -- a Case Study in Missisquoi River Watershed written by Linyuan Shang and published by . This book was released on 2019 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Watershed regulation of water, carbon and nutrient dynamics support food, drinking water and human development. Projected climate changes and land use/cover change (LUCC) have been identified as drivers of watershed nutrient and hydrological processes and are likely to happen jointly in the future decades. Studying climate change and LUCC impacts on watersheds' streamflow and nutrients dynamics is therefore essential for future watershed management. This research aimed to unveil how climate change and LUCC affect water and nutrient dynamics in the Missisquoi River watershed, Vermont. We used 12 scenarios of future climate data (2021 - 2050) generated by three GCMs (ccsm4, mri-cgcm3, and gfdl-esm2m) under four Representative Concentration Pathways (RCPs). For LUCC, we used three different scenarios generated by the Interactive Land Use Transition Agent-Based Model (ILUTABM). The three LUCC scenarios were Business As Usual (BAU), Prefer Forest (proForest), and Prefer Agriculture (proAg). New land use maps were generated every 10 years for the period of 2021 - 2050. Combining each climate change and LUCC scenario resulted in 36 scenarios that were used to drive Regional Hydro-Ecologic Simulation System (RHESSys) ecohydrological model. In chapter 3, we used RHESSys to study streamflow. We found climate was the main driver for streamflow because climate change directly controlled the system water input. For streamflow, climate change scenarios had larger impacts than LUCC, different LUCCs under the same climate change scenario had similar annual flow patterns. In chapter 4, we used RHESSys to study streamflow NO3-N and NH4-N load. Because fertilizer application is the major source for nitrogen export, LUCC had larger impacts; watersheds with more agricultural land had larger nitrogen loads. In chapter 5, we developed RHESSys-P by coupling the DayCent phosphorus module with RHESSys to study climate change and LUCC impacts on Dissolved Phosphorus (DP) load. RHESSys-P was calibrated with observed DP data for 2002 - 2004 and validated with data for 2009 - 2010. In both calibration and validation periods, simulated DP basically captured patterns of observed DP. In the validation period, the R2 of simulated vs observed DP was 0.788. Future projection results indicated BAU and proForest annual loads were around 4.0 x 104 kg under all climate change scenarios; proAg annual loads increased from around 4.0 x 104 kg in 2021 to 1.6 x 105 kg in 2050 under all climate change scenarios. The results showed LUCC was the dominant factor for dissolved phosphorus loading. Overall, our results suggest that, while climate drives streamflow, N and P fluxes are largely driven by land use and management decisions. To balance human development and environmental quality, BAU is a feasible future development strategy.
