Available in PDF, EPUB and Kindle. Book excerpt: The need for accurate information on the state and evolution of tropical forest types at regional and continental scales is widely recognized, particularly to analyze the forest diversity and dynamics, to assess degradation and deforestation processes and to better manage these natural resources. Here we document the approach that was developed by JRC to map and monitor the extent of moist tropical forests and their changes (degradation, deforestation and regrowth) over the last three decades (1990-2020) at fine spatial resolution (30 m × 30 m). The approach is based on the analysis of each valid observation from the Landsat archive and allows to capture disturbances with a short-duration appearance on satellite imagery such as selective logging, fires, and severe weather events (hurricanes, dryness). This new approach allows characterizing the sequential dynamics of forest cover changes by providing transition stages from the initial observation period to the most recent year (2019 for this report). For the first time at the pantropical scale the occurrence and extent of forest degradation can be documented on an annual basis in addition to the monitoring of deforestation. After a short introduction (chapter 1), this technical report describes the study area (chapter 2), the input data (chapter 3), the method that has been developed (chapter 4), and the outcomes of this study (chapter 5). A discussion is also provided regarding the specificities and added value of the outcomes (chapter 6), and the known limitations and future expected improvements (chapter 7). This new pan-tropical scale deforestation and forest degradation monitoring system will contribute to the EU Observatory on deforestation, forest degradation, changes in the world's forest cover, and associated drivers, which is an action being implemented in the framework of the Communication from the Commission to step up EU action to protect and restore the World's forests (COM(2019) 352).

This book was released on 2023-07-26 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides global and regional estimates of the area covered by mangrove forests, including area changes between 2000 and 2020. It analyses the drivers of these global, regional and subregional changes for the periods 2000–2010 and 2010–2020 with the aim of improving understanding of these drivers, their interactions and how their relative importance has shifted over time. In the study that underpins this report, FAO developed and validated an easy, repeatable methodology that integrates remote sensing with local knowledge. An FAO team and 48 image interpreters worldwide collected and analysed data on mangrove area in 2020, change in mangrove area between 2000 and 2020, and the drivers of change over the two decades. It is the first global study of mangrove area to provide information on land use rather than land cover.

Download or read book Tropical Rainforest Responses to Climatic Change written by Mark B. Bush and published by Springer Science & Business Media. This book was released on 2007 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide a current overview of the impacts of climate change on tropical forests, to investigate past, present, and future climatic influences on the ecosystems with the highest biodiversity on the planet.Tropical Rainforest Responses to Climatic Change will be the first book to examine how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis onto ecological processes e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of this book that emerges progressively is the interaction between humans, climate and forest ecology. While numerous books have appeared dealing with forest fragmentation and conservation, none have explicitly explored the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, coupled with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging.

Download or read book Statistical Strategies for Global Monitoring of Tropical Forests written by Raymond L. Czaplewski and published by . This book was released on 1991 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Food and Agricultural Organization (FAO) of the United Nations is conducting a global assessment of tropical forest resources, which will be accomplished by mid-1992. This assessment requires, in part, estimates of the total area of tropical forest cover in 1990, and the rate of change in forest cover between 1980 and 1990. This paper describes: (1) the strategic process used to select the statistical and remote sensing methods that accomplish this objective, (2) general details and expected precision of the selected method, and (3) recommendations for monitoring and assessment actions after 1992.
Download or read book Tropical Rainforest Responses to Climatic Change written by Mark Bush and published by Springer. This book was released on 2011-08-17 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This updated and expanded second edition of a much lauded work provides a current overview of the impacts of climate change on tropical forests. The authors also investigate past, present and future climatic influences on the ecosystems with the highest biodiversity on the planet. Tropical Rainforest Responses to Climatic Change, Second Edition, looks at how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis on to ecological processes, e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of the book is the interaction between humans, climate and forest ecology. The authors, all foremost experts in their fields, explore the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, together with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging. This second edition provides an updated text in this rapidly evolving field. The existing chapters are revised and updated and two entirely new chapters deal with Central America and the effect of fire on wet forest systems. In the first new chapter, the paleoclimate and ecological record from Central America (Lozano, Correa, Bush) is discussed, while the other deals with the impact of fire on tropical ecosystems. It is hoped that Jonathon Overpeck, who has been centrally involved in the 2007 and 2010 IPCC reports, will provide a Foreword to the book.
Download or read book Reforesting the Earth written by Thomas K. Rudel and published by Columbia University Press. This book was released on 2023-09-05 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests offer a natural solution to the climate crisis. Conserving and expanding them not only removes carbon from the atmosphere but also protects and fosters biodiversity. Yet the results of elite-driven reforestation initiatives have been disappointing, and in many world regions deforestation continues relentlessly. Thomas K. Rudel examines a wide range of conservation and reforestation efforts to shed new light on the social factors that lead to success. He details effective coalition-building strategies and organizational models that have protected, restored, and expanded forests around the world. Rudel argues that successful reforestation projects bring together diverse groups of people with a stake in the land and a commitment to collective decision making. They give voice to different economic and social interests, including small farmers, Indigenous peoples, loggers, ranchers, government officials, NGO personnel, international donors, and climate activists. These varied coalition members each make commitments to promote forests. Farmers limit the extent of lands under cultivation, governments protect land tenure for smallholders, and wealthy donors make payments for environmental protections. Timely and accessible, Reforesting the Earth offers a guide to scaling up local efforts to sequester carbon and makes a powerful case for a global reforestation movement.

This book was released on 2018-07-06 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly three years ago, world leaders agreed to the United Nations 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs) – the central framework for guiding development policies throughout the world. This edition of The State of the World’s Forests is aimed at enhancing our understanding of how forests and their sustainable management contribute to achieving several of the SDGs. Time is running out for the world’s forests: we need to work across sectors, bring stakeholders together, and take urgent action. The State of the World’s Forests 2018 identifies actions that can be taken to increase the contributions of forests and trees that are necessary to accelerate progress towards the SDGs. It is now critical that steps be taken to work more effectively with the private sector, and the informal forest sector must be transformed in order to bring broader economic, social and environmental benefits. Seventy years ago, when FAO completed its first assessment of the world’s forest resources, the major concern was whether there would be enough timber to supply global demand; now we recognize the greater global relevance of our forests and trees. For the first time, The State of the World’s Forests 2018 provides an assessment of the contribution of forests and trees to our landscapes and livelihoods. The purpose of this publication is to provide a much wider audience with an understanding of why forests and trees matter for people, the planet and posterity.

Download or read book Remote Sensing Time Series written by Claudia Kuenzer and published by Springer. This book was released on 2015-04-28 with total page 458 pages. 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.
Download or read book Estimation of Pan tropical Deforestation and Implications for Conservation written by Do-Hyung Kim and published by . This book was released on 2015 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing tropical deforestation has been a primary focus for the implementation of policies that are aimed at biodiversity conservation, and reducing greenhouse gas emissions, as tropical forests have, biologically, the richest ecosystem on Earth, tropical deforestation is one of the largest sources of anthropogenic carbon emission into the atmosphere, and preventing it is the most inexpensive option, in order to reduce carbon emissions and conserve biodiversity. To set the effective policies and conservation plans to reduce emission from tropical deforestation, the evaluation of effectiveness of both the current and previous efforts for conservation is critical. The three studies in this dissertation describe the development of the methods to accurately monitor pan-tropical forest cover change, using satellite remote sensing data, and their integration with the econometrics approach, to evaluate the effectiveness of the tropical forest conservation practices. The dissertation contributes a method for long-term, global forest cover change estimation from Landsat, and the methods are applied to report the first, pan-tropical forest cover change trends, between the 1990s and the 2000s. The global forest cover change product from 1990 to 2000, which was produced, based on the developed methods which are evaluated to have an overall accuracy of 88%. The results demonstrate that tropical deforestation has accelerated between the 1990s and the 2000s by 62%, which contradicts the assertions of it being decelerating. The results further show that the increased deforestation rate between the 1990s and the 2000s is significantly correlated with the increases in Gross Domestic Product (GDP) growth rate, agricultural production growth, and urban population growth between the two decades. Protected Areas (PA), throughout the tropics, avoided 83,000 ± 22,000 km2 of the deforestation during the 2000s. The effectiveness of international aid can be suppressed by weak governance and the lack of forest change monitoring capacity of each country. The conclusions of this dissertation provide a historical baseline for the estimates of tropical forest cover change, and for the evaluation of effectiveness of such conservation efforts.
