Advancing Land Change Modeling


Book Description

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


Book Description

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.




The Land Governance Assessment Framework


Book Description

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.




Population, Land Use, and Environment


Book Description

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.

Statistical Methods in Water Resources


Book Description

Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.
