Download or read book Monitoring Forest Cover and Land Use Change in Forest Reserves Connecting Satellite Imagery to Anthropogenic Impacts written by and published by . This book was released on 2018 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Monitoring Forest Policy from Space written by Daniel Hammer and published by . This book was released on 2017 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Geo Spatial Tools for Forest Cover Change and Susceptibility Analysis written by Mulugeta Sebhatleab Tesfay and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests provide a wide variety of ecological and socio-economic benefits including; conservation of biodiversity, carbon storage, and then enhance livelihoods. But reduction in the natural forest cover due to anthropogenic and natural calamities impacted those services. Today it is an urgent environmental issue of conserving those natural forests remnants like that of the dry Afromontane of Northern Ethiopia. To quantify the level of the problem and plan proper mitigation measures, knowledge on the extent of these land use changes is very important. GIS and remote sensing techniques then provide information on the spatial and temporal cover changes at low cost and time. This book, therefore, explains the status and trend of forest cover changes in Northern Ethiopia, application of GIS and remote sensing in detecting the trend of spatial and temporal forest cover changes, mapping the susceptible areas to deforestation for conservation decisions, and the major factors of deforestation. This book is supposed to be useful especially professionals in geographical information, forest ecosystem management studies, or anyone else who is involved land resources management and monitoring.

This book was released on 2021-12-01 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: CLIMATE IMPACTS ON SUSTAINABLE NATURAL RESOURCE MANAGEMENT Climate change has emerged as one of the predominant global concerns of the 21st century. Statistics show that the average surface temperature of the Earth has increased by about 1.18°C since the late 19th century and the sea levels are rising due to the melting of glaciers. Further rise in the global temperature will have dire consequences for the survival of humans on the planet Earth. There is a need to monitor climatic data and associated drivers of changes to develop sustainable planning. The anthropogenic activities that are linked to climate change need scientific evaluation and must be curtailed before it is too late. This book contributes significantly in the field of sustainable natural resource management linked to climate change. Up to date research findings from developing and developed countries like India, Indonesia, Japan, Malaysia, Sri Lanka and the USA have been presented through selected case studies covering different thematic areas. The book has been organised into six major themes of sustainable natural resource management, determinants of forest productivity, agriculture and climate change, water resource management and riverine health, climate change threat on natural resources, and linkages between natural resources and biotic-abiotic stressors to develop the concept and to present the findings in a way that is useful for a wide range of readers. While the range of applications and innovative techniques is constantly increasing, this book provides a summary of findings to provide the updated information. This book will be of interest to researchers and practitioners in the field of environmental sciences, remote sensing, geographical information system, meteorology, sociology and policy studies related to natural resource management and climate change.

Available in PDF, EPUB and Kindle. Book excerpt: Critical Political Ecology brings political debate to the science of ecology. As political controversies multiply over the science underlying environmental debates, there is an increasing need to understand the relationship between environmental science and politics. In this timely and wide-ranging volume, Tim Forsyth uses an innovative approach to apply political analysis to ecology, and demonstrates how more politicised approaches to science can be used in environmental decision-making. Critical Political Ecology examines: *how social and political factors frame environmental science, and how science in turn shapes politics *how new thinking in philosophy and sociology of science can provide fresh insights into the biophysical causes and impacts of environmental problems *how policy and decision-makers can acknowledge the political influences on science and achieve more effective public participation and governance.

Download or read book Remote Sensing Applications in Monitoring of Protected Areas written by Yeqiao Wang and published by MDPI. This book was released on 2020-12-02 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing has been successfully applied in monitoring of protected areas around the world. With intensified impacts of climate and environmental change, protected areas become increasingly important to serve as indicators of and buffers against the impacts of the disturbances. Remote sensing plays an irreplaceable role in this frontline of challenges. The subjects and contents of the articles collected in this book reflect the state-of-the-art applications of remote sensing for capturing dynamics of environmental and ecological variations of the protected areas. The examples include revealing the level, growth rate, trend, and distribution pattern of the night-time light of global protected areas; quantifying the energy budget, water cycle, and carbon sink over the Three-River Headwaters Region in the hinterland of the Tibetan Plateau; monitoring wetland change in a cross-boundary zone between Northeast China and the Russian Far East; and monitoring applications and change analyses in protected areas of boreal forests, dryland shrubs, coastal salt marshes, large lakes, and temperate semi-humid to semi-arid transitional agricultural regions, using a variety of sensor data with innovative approaches. Also included in this collection is a bibliometric analysis that suggests the intellectual structure in remote sensing of protected areas from the perspective of journal publications.
Download or read book Evaluating the Efficacy of Remote Sensing Techniques in Monitoring Forest Cover and Forest Cover Change in the Mount Cameroon Region written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mount Cameroon region is experiencing rapid and continuous changes mainly due to anthropogenic influences (wood extraction and agricultural extension). The changes occur at varying spatial scales most often not more than 250 m for small scale farms and extraction of fuelwood; extending to hundreds of hectares for plantation agriculture and commercial logging. Given the importance of land use and land cover data in conservation planning, accurate and efficient techniques to provide up-to-date data are required. Techniques based on multi-temporal, multi-spectral, satellite-sensor-acquired data have demonstrated great potential as a means to detect, identify, map and monitor forest cover and forest cover changes irrespective of their causal agents. Nevertheless variable opinions still exist about the value and appropriateness of these techniques due to landscape complexities of study areas and data used. Moreover, forest cover change is a location specific problem with the effect, pattern and magnitude of identified drivers not just differing from country to country but also from one region to another. Consequently, it is absolutely necessary to devise techniques that empirically determine the extent and identify the magnitude at which factors identified, influence the continuous changes in forest cover patterns. Furthermore, given that many different factors influence changes in forest cover and that these factors operate at different levels, mixing up the factors of various levels generally leads to a wrong specification of the causal relationships between variables. It is thus of utmost importance to understand the role of each of these factors on forest cover change. The thesis summarises the methods and results of applying different thematic information extraction algorithms as well as different change detection algorithms to monitor forest cover and forest cover change in the mount Cameroon region. Furthermore, the study sought to explain the forest cover cha.
