This book was released on 2012 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Northern Mongolia, significant land-use and land-cover changes have taken place in the last decades affecting the ecosystems and their functions. Together with climate change, decreasing water availability and the rapid increase in water demand, integrated approaches are required to evaluate the impacts on humans and the environment. The aim of this thesis was the development and application of a regional model of the land system that is capable of simulating historical, current and future land-use and land-cover changes. Within three case studies (agricultural intensification, impacts of forest and steppe wildfires, environmental scenarios) important aspects of land-use change impacts are simulated and discussed. The thesis contributes to develop management measures for an integrated water resources management on river-basin scale.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to describe what is currently occurring in the Mongolian grasslands, to analyze how various factors creating environmental problems interact, and to suggest solutions for sustainable management of the grasslands. The book has three parts. Part I is an introduction, explaining the key concept of an ecosystem network and providing background information on the general features of Mongolian nomadic pastoralism as well as distribution of vegetation in Mongolian grasslands. Part II describes the effects of natural environmental factors and nomadic activities on grassland conditions. Water dynamics that maintain the grassland system are analyzed in a steppe region with shrubs and in a forest-steppe region with trees. Part III describes the effects of economic and social factors on land-use and the livelihood of herders. As nomadic people moved closer to large cities for economic advantage in the 1990s, degradation of pastures by overgrazing resulted. Finally, the impacts of global warming and globalization on the Mongolian society and ecosystem are examined. This book analyzes environmental problems in Mongolian grasslands, but the contents contribute to consideration of environmental problems and sustainable pasture use in grassland areas worldwide.

Download or read book Land Use Impacts on Climate written by Xiangzheng Deng and published by Springer. This book was released on 2014-06-11 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a key issue in research on the climatic impact of land cover and land use changes via terrestrial biogeophysical processes. The parameterization of surface processes and a systematic approach to modeling the climatic impacts of land use change are discussed respectively, and can be used to improve parameterization schemes for climate numerical models and to provide a systematic method, thus offering more scientific and enhanced support for research on the climatic effects of land use/cover change. Further, based on predictions and scenario analyses of land use changes in typical zones, the climatic impact of various types of changes in different areas can be simulated through climatic numerical modeling, the simulation results are suitable for use in climate mitigation, land use planning, urban development planning, etc. Thus, the book is intended for researchers and professionals working in the area of meteorology systems, climatic numerical modeling, climate change, and land use/cover change, as well as decision makers in meteorology and land use planning. Professor Xiangzheng Deng is a senior research fellow at the Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences.
Download or read book Water and Environment in the Selenga Baikal Basin written by Daniel Karthe and published by Columbia University Press. This book was released on 2016-03-15 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The water resources of the Selenga River/Lake Baikal system are essential to the ecosystems and economic development of the surrounding region. In this large river and lake basin, there are strong contrasts between relatively pristine areas and massive anthropogenic impacts on the environment. The effects of climate change are more pronounced than in most other parts of the earth, and the transition from socialism into a market-oriented economy has led to a boom in mining but also to a partial collapse of environmental monitoring and urban wastewater management systems. Moreover, the expansion of agriculture and mining has triggered considerable land use change, rising water consumption, and the release of contaminants that had previously been unknown to the region. The consequences for the water resources and the aquatic and terrestrial ecosystems depending on them have become increasingly visible in recent years. This book, which is based on contributions to the 2014 Bringing Together Selenga-Baikal Research Conference, provides multidisciplinary insight into current water-related challenges and strategies for their solution from the viewpoint of the international scientific community.
Download or read book Advancing Land Change Modeling written by National Research Council and published by National Academies Press. This book was released on 2014-03-31 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

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 Land Use and Land Cover Mapping in Europe written by Ioannis Manakos and published by Springer. This book was released on 2014-07-08 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land use and land cover (LULC) as well as its changes (LUCC) are an interplay between bio-geophysical characteristics of the landscape and climate as well as the complex human interaction including its different patterns of utilization superimposed on the natural vegetation. LULC is a core information layer for a variety of scientific and administrative tasks(e.g. hydrological modelling, climate models, land use planning).In particular in the context of climate change with its impacts on socio-economic, socio-ecologic systems as well as ecosystem services precise information on LULC and LUCC are mandatory baseline datasets required over large areas. Remote sensing can provide such information on different levels of detail and in a homogeneous and reliable way. Hence, LULC mapping can be regarded as a prototype for integrated approaches based on spaceborne and airborne remote sensing techniques combined with field observations. The book provides for the first time a comprehensive view of various LULC activities focusing on European initiatives, such as the LUCAS surveys, the CORINE land covers, the ESA/EU GMES program and its resulting Fast-Track- and Downstream Services, the EU JRC Global Land Cover, the ESA GlobCover project as well as the ESA initiative on Essential Climate Variables. All have and are producing highly appreciated land cover products. The book will cover the operational approaches, but also review current state-of-the-art scientific methodologies and recommendations for this field. It opens the view with best-practice examples that lead to a view that exceeds pure mapping, but to investigate into drivers and causes as well as future projections.
