Book excerpt: This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and water developments at the catchment scale.

Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises an outstanding variety of chapters on Earth Observation based time series analyses, undertaken to reveal past and current land surface dynamics for large areas. What exactly are time series of Earth Observation data? Which sensors are available to generate real time series? How can they be processed to reveal their valuable hidden information? Which challenges are encountered on the way and which pre-processing is needed? And last but not least: which processes can be observed? How are large regions of our planet changing over time and which dynamics and trends are visible? These and many other questions are answered within this book “Remote Sensing Time Series Analyses – Revealing Land Surface Dynamics”. Internationally renowned experts from Europe, the USA and China present their exciting findings based on the exploitation of satellite data archives from well-known sensors such as AVHRR, MODIS, Landsat, ENVISAT, ERS and METOP amongst others. Selected review and methods chapters provide a good overview over time series processing and the recent advances in the optical and radar domain. A fine selection of application chapters addresses multi-class land cover and land use change at national to continental scale, the derivation of patterns of vegetation phenology, biomass assessments, investigations on snow cover duration and recent dynamics, as well as urban sprawl observed over time.

Available in PDF, EPUB and Kindle. Book excerpt: This book answers key questions about environment, people and their shared future in deltas. It develops a systematic and holistic approach for policy-orientated analysis for the future of these regions. It does so by focusing on ecosystem services in the world’s largest, most populous and most iconic delta region, that of the Ganges-Brahmaputra delta in Bangladesh. The book covers the conceptual basis, research approaches and challenges, while also providing a methodology for integration across multiple disciplines, offering a potential prototype for assessments of deltas worldwide. Ecosystem Services for Well-Being in Deltas analyses changing ecosystem services in deltas; the health and well-being of people reliant on them; the continued central role of agriculture and fishing; and the implications of aquaculture in such environments.The analysis is brought together in an integrated and accessible way to examine the future of the Ganges Brahmaputra delta based on a near decade of research by a team of the world’s leading scientists on deltas and their human and environmental dimensions. This book is essential reading for students and academics within the fields of Environmental Geography, Sustainable Development and Environmental Policy focused on solving the world’s most critical challenges of balancing humans with their environments.

Download or read book Land Cover Change Analysis of Big Creek Conservation Area with Satellite Remote Sensing written by Chen Shang and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the relatively complex land cover configuration and a series of significant ecological implications, the issue of land cover changes in the Big Creek area are of critical value to environmental conservation groups, policy makers, and relevant stakeholders. In consultation with the Carolinian Canada Coalition (CCC), the potential of IKONOS imagery as a high spatial resolution remote sensing product is assessed for significant habitat mapping, and a change detection methodology is developed and implemented for the Big Creek area that will be of value to decision makers and policy analysts. In order to take advantage of the synergistic strengths of multiple change detection techniques, a hybrid approach is adopted in this study, aiming to detect and stratify land cover changes over the time span from 2004 to 2012. On the basis of an assessment of the capability of differentiating changed from unchanged areas, the image differencing method based on Normalized Difference Vegetation Index (NDVI) was found to be the most accurate among the three change detection techniques employed in this study. As an attempt to incorporate local spatial autocorrelation information into the change detection analysis, the Getis statistic was used as a spatial filter in conjunction with the image differencing technique, and it showed great promise for improving the change/no change maps both qualitatively and quantitatively. In particular, the extreme Getis statistic proposed in this study demonstrated strong potential for automatically determining the optimal scale for spatial smoothing, which could greatly improve the efficiency and accuracy of change detection practices. In addition, the performance of the post-classification comparison approach was found to be highly dependent on the intrinsic characteristics of the individual classified maps, rather than simply the accuracy scores of the classifications subject to the comparison. Therefore, it is recommended that a benchmark approach be taken to compensate for this uncertainty of the post-classification comparison method, such that the negative impact of the misclassification errors in the individual classified maps could be reduced to an acceptable level. The findings of this research will contribute to a better understanding of the usefulness of some widely used change detection techniques in a relatively complex physical environment with abundant vegetation cover. In addition, the application of the Getis statistic as a spatial filter is proven useful for suppressing potential "salt and pepper" effects in the context of change detection analysis, especially if high spatial resolution imagery is employed. With minor modifications, the workflow proposed in this study is likely to reliably fulfill the purpose of monitoring land cover dynamics in other environments as well. However, it should be noted that clear awareness of the characteristics of the study area and needs of information is a premise to the successful application of any change detection approach in different environments.

This book was released on 2013-06-25 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the development of remote sensing techniques focuses greatly on construction of new sensors with higher spatial and spectral resolution, it is advisable to also use data of older sensors (especially, the LANDSAT-mission) when the historical mapping of land use/land cover and monitoring of their dynamics are needed. Using data from LANDSAT missions as well as from Terra (ASTER) Sensors, the authors shows in his book maps of historical land cover changes with a focus on agricultural irrigation projects. The kernel of this study was whether, how and to what extent applying the various remotely sensed data that were used here, would be an effective approach to classify the historical and current land use/land cover, to monitor the dynamics of land use/land cover during the last four decades, to map the development of the irrigation areas, and to classify the major strategic winter- and summer-irrigated agricultural crops in the study area of the Euphrates River Basin.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water productivity; developing a better understanding of present patterns of water use and impacts of interventions; improving communication among professionals and communication to non-water professionals; and improving the rationale for allocation of water among uses. It is expected that with further application, these water accounting concepts will evolve into a robust, supporting methodology for water basin analysis.

Download or read book Public Policies and the Misuse of Forest Resources written by World Resources Institute and published by Cambridge University Press. This book was released on 1988-09-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six contributors explore the role of governments in accelerating the rate of forest destruction by providing direct and indirect subsidies to support what would otherwise be non-commercial logging operations. Without these financial incentives, most timber operations in the tropics would cease. In a series of country-by-country investigations, including examples from the developed and developing worlds, this book documents the government policies that are leading to the misuse of forest resources. Each is written by an authority on the county, and each contains descriptive, analytical and empirical material on key policies and their effects. The final country analysis focuses on the United States, where the consequences of the subsidized timber sales by the US Forest Service from most of the national forests are discussed. The book concludes with an overview of the impact of forest policies and the role of bilateral and multilateral agencies in their formulation. By directing attention toward the political dimension involved in forest clearance, this book will provide a clearer insight into the basic reasons why forests continue to be destroyed despite the outcry raised by conservationists.

This book was released on 2012 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The worlds forests are critical for human livelihoods. Increasingly they are being recognized for the wide range of products and essential ecosystem services they provide. Accurate and up-to-date information on the extent of the worlds forests, and the way they are changing, has never been more important. This report on the FRA 2010 Remote Sensing Survey is the first of its kind to present systematic estimates of global forest land use and change. It is the result of many years of planning and three years of detailed work by staff at FAO and the European Commission Joint Research Centre (JRC), with inputs from technical experts from more than 100 countries. From its outset, the ambitious goal of the FRA 2010 Remote Sensing Survey has been to use remote sensing data to obtain globally consistent estimates of forest area and changes in tree cover and forest land use between 1990 and 2005.

This book was released on 2019-10-17 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents essential case studies on the integrated modelling of ecosystem services and land-use change in the field of landscape ecology. The case studies were mainly conducted in the Zhangye oasis of the Hexi corridor and the upper reaches of the Heihe river basin, including Loess plateau (for wind power) and the inland waterways of the Yangtze River (for the regulation of extreme events). The book puts forward an integrated modelling method, including human activities, natural processes, land-use change, and ecosystem management, and explores multiple scenarios based on the interests of local managers and their implications for ecosystem services. As the book demonstrates, the integrated modelling method for ecosystem services and land-use change can serve as a valuable tool for gauging the impact of various development scenarios in this study area, and in other regions with similar characteristics. In addition, numerous charts and diagrams are included in each chapter, facilitating the simulation and assessment of specific land-use change impacts on ecosystem services in various study areas.
