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.

Environmental Statistics, Assessment, and Forecasting examines the current efforts to develop a coherent picture of national and regional environmental trends and conditions. The book includes sampling methodologies, statistical analysis techniques, environmental modeling, graphic presentation, including geographic information systems (GIS), and the problems involved in forecasting the future. The sampling and statistical techniques discussed include dealing with large variability and soft data; composite sampling; methods for combining data; data below the detection level; multivariate data; spatially censored, artificially censored, and incomplete data; kriging; and imputation. Geographic information system (GIS) analysis is discussed in the context of database management systems. Also covered are topics involved in the future of environmental statistics, including research planning, a bureau of environmental statistics, global interactions, and communication techniques. The book will interest statistical analysts, environmental planners, scientists, regulators, and policy makers in government, industry, and environmental groups.

"Geospatial Information" is spatial data concerning a place or, in space, collected in real time. Geospatial techniques together with remote sensing, geographic information science, Global Positioning System (GPS), cartography, geovisualization, and spatial statistics are being used to capture, store, manipulate and analyze to understand complex situations to solve mysteries of the universe. These techniques have been applied in various fields such as meteorology, forestry, environmental management, agriculture, health, homeland security etc. around the globe. This volume presents case studies and examples from various parts of the world and provides a broad overview of various approaches; data sets; data acquiring, monitoring and dissemination methods; satellites and sensors; tools and techniques used; integrating tools, techniques and application to various fields for the sustainable management of environmental resources in the context of global environmental change and natural hazards. The objective of this book is to provide state-of-the-art information to academics, researchers and industry practitioners who are involved or interested in the study, use, design and development of advanced and emerging geospatial technologies around the world with ultimate aim to empower individuals and organizations in building competencies for exploiting the opportunities of the knowledge society. All the chapters are peer-reviewes and evaluated and are an inter- and multi-disciplinary source of information, making an effort to link various geospatial techniques to make the earth an habitable place. The contributors have tried to focus their respective views on the current problems that need urgent attention. Consequently, we see this book as a comprehensive information base, which includes work of expertise in their specific fields of research.

Population, Land Use, and Environment: Research Directions offers recommendations for future research to improve understanding of how changes in human populations affect the natural environment by means of changes in land use, such as deforestation, urban development, and development of coastal zones. It also features a set of state-of-the-art papers by leading researchers that analyze population-land useenvironment relationships in urban and rural settings in developed and underdeveloped countries and that show how remote sensing and other observational methods are being applied to these issues. This book will serve as a resource for researchers, research funders, and students.

Increased global demand for land posits the need for well-designed country-level land policies to protect long-held rights, facilitate land access and address any constraints that land policy may pose for broader growth. While the implementation of land reforms can be a lengthy process, the need to swiftly identify key land policy challenges and devise responses that allow the monitoring of progress, in a way that minimizes conflicts and supports broader development goals, is clear. The Land Governance Assessment Framework (LGAF) makes a substantive contribution to the land sector by providing a quick and innovative tool to monitor land governance at the country level. The LGAF offers a comprehensive diagnostic tool that covers five main areas for policy intervention: Legal and institutional framework; Land use planning, management and taxation; Management of public land; Public provision of land information; and Dispute resolution and conflict management. The LGAF assesses these areas through a set of detailed indicators that are rated on a scale of pre-coded statements (from lack of good governance to good practice). While land governance can be highly technical in nature and tends to be addressed in a partial and sporadic manner, the LGAF posits a tool for a comprehensive assessment, taking into account the broad range of issues that land governance encompasses, while enabling those unfamiliar with land to grasp its full complexity. The LGAF will make it possible for policymakers to make sense of the technical levels of the land sector, benchmark governance, identify areas that require further attention and monitor progress. It is intended to assist countries in prioritizing reforms in the land sector by providing a holistic diagnostic review that can inform policy dialogue in a clear and targeted manner. In addition to presenting the LGAF tool, this book includes detailed case studies on its implementation in five selected countries: Peru, the Kyrgyz Republic, Ethiopia, Indonesia and Tanzania.
