Book Description
Satellite imagery is an increasingly valuable data source in agricultural and resource economics. It offers credible, consistent, and globally comparable information on landscape-scale changes to the environment; and the supply of the information is accelerating with innovations in satellite technology. This dissertation presents the critical value of satellite imagery for environmental policy evaluation, focusing specifically on deforestation. Tropical deforestation may account for as much as one tenth of net global greenhouse gas emissions each year. Any viable effort to mitigate the impact of climate change must address deforestation. The effective design of forest policy is dependent on reliable impact analysis. Satellites offer a method of direct observation of forest cover loss, rather than incomplete or biased estimates. The dissertation first presents an algorithm to convert raw satellite imagery into a new and novel data source on tropical deforestation. Next, the data are used to explain the counter-intuitive outcomes from a 2012 conservation policy in Indonesia, relying on the spatial detail afforded by the new data. Finally, a set of empirical results describe the relationship of deforestation to interest rates, commodity prices, and other economic variables, using the temporal detail afforded by the new data. Together, these case studies demonstrate the effective use of a new data source in direct and credible policy analysis for natural resource economics.

Book Description
Covering recent developments in satellite observation data undertaken for monitoring forest areas from global to national levels, this book highlights operational tools and systems for monitoring forest ecosystems. It also tackles the technical issues surrounding the ability to produce accurate and consistent estimates of forest area changes, which are needed to report greenhouse gas emissions and removals from land use changes. Written by leading global experts in the field, this book offers a launch point for future advances in satellite-based monitoring of global forest resources. It gives readers a deeper understanding of monitoring methods and shows how state-of-art technologies may soon provide key data for creating more balanced policies.

Book Description
This briefing note presents some recent developments in satellite-based earth observation (EO) and how new and disruptive technology can improve understanding on tropical dry forests. It focuses on tools and algorithms developed by the Satellite Monitoring for Forest Management (SMFM) project financed by the Global Environment Facility (GEF) and implemented by the World Bank in 2017-2020. This note summarizes the key aspects on using satellite data in dry forest monitoring and its target audience is senior forest managers, policy makers and other users of forest data. For more technology focused audience, the SMFM project also prepared a series of other documents: i) good practice guidance - a guidance document for dry forest assessment and monitoring; ii) validation compliance report; iii) project implementation summary; and iv) working practice document (manual) for each tool developed under the project.

Book Description
The demand for comparable, long-term, high quality data on forest ecosystems' status and changes is increasing at the international and global level. Yet, sources for such data are limited and in many case it is not possible to compare data from different monitoring initiatives across space and time because of methodological differences. Apart from technical manuals, there is no comprehensive multidisciplinary, scientific, peer-reviewed reference for forest monitoring methods that can serve and support the user community. This book provides in a single reference the state-of-the-art of monitoring methods as applied at the international level.The book present scientific concepts and methods that form the basis of the transnational, long-term forest monitoring in Europe and looks at other initiatives at the global level. Standardized methods that have been developed over two decades in international forest monitoring projects are presented. Emphasis is put on trans-nationally harmonized methods, related data quality issues, current achievements and on remaining open questions. - A comprehensive overview of needs, requirements, organization and possible outcomes of an integrated monitoring program - Tested and quality assured, internationally harmonized methodologies based on a complete revision of existing methods carried out in 2009-2011 - Connection with monitoring results allows assessment of the potential of the monitoring method

Book Description
Despite their protected status, forest reserves can be influenced by anthropogenic activities within and adjacent to reserve boundaries, resulting in environmental degradation and changes in forest cover. Long-term monitoring of environmental change within protected areas in a reliable and extensive manner is important given widespread, human-induced land-cover and land-use change. This study demonstrates the utility of optical satellite remotely sensed imagery and multi-temporal image analysis procedures for mapping and monitoring land cover and land use within cloud-prone and mountainous forest reserves and their environs in China and Ghana for the period of mid-1980s to 2018. The novel mapping and monitoring procedures yield extensive land-use dynamic information in a reliable manner by minimizing terrain-related illumination and cloud cover effects. Forest types and land-use are mapped in selected cloud-prone and mountainous forest reserves in China and Ghana to test the reliability of the optimized methods. By applying logical land-use transition rules and interpreting high spatial resolution satellite imagery, land-use changes and the anthropogenic activities associated with them are identified. Vegetation and land-use types are mapped with moderate to high classification accuracies (64 to 94%) for study areas in China and Ghana. For Fanjingshan National Nature Reserve in China, 12 km2 in land area is mapped as afforested bamboo and conifer lands associated with payment for ecosystem services programs, and over 25 km2 is mapped as new development during 1995-2016. Forest area decreased by 9% for the 76 study reserves and environs in southern Ghana between 2000 and 2018. Substantial land changes associated with built development and agricultural expansion are observed in reserve environs within both study areas. Other anthropogenic activities including mining and plantation activities are identified in southern Ghana reserves, while afforestation activities associated with payment for ecosystem programs were predominant adjacent to Fanjingshan in China. This study contributes to the land-cover and land-use mapping literature by developing and optimizing methods for extremely cloud prevalent and mountainous regions. A semi-automated mapping approach implemented on an open-access, user-friendly platform, similar to the workflow demonstrated in this study, increases the usability and transferability of such mapping techniques. Improved monitoring of other forested, mountainous, and cloud prevalent regions can benefit and inform protected area management and policy, long-term environmental change monitoring, and conservation effort assessment.

Book Description
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.
