The natural environment of drylands is highly vulnerable and fra¬gile, variations of climate conditions here are the highest among all terrestrial ecosystems and that is why they are expected to be strongly influenced by the current climate change. Remote sensing and GIS play an important role in a better understanding about the nature of climate impacts on the drylands as a whole system and on the vegetation cover as the most important component of this ecosystem at all scales from global to regional and local. This book is one of the first to examine the dynamics of drylands in Kazakhstan using time series of remote sensing derived data and climate records over the last 20 years. The author investigated the problem from different views and combined analyses at multiple time and spatial scales. The entire spectrum of the interrelationship between climate and vegetation cover - spatial and temporal, on the regional, subregional and local scale, interannual and within the growing season -, has been analysed, described and discussed. A new monitoring approach was presented which enables discrimination between climatic and anthropogenic forces in the complex of dryland dynamics. The text improves the understanding of the nature and mechanisms of the ecosystem dynamics in the internal Eurasia and provides the basis for predicting changes in vegetation productivity that accompany changes in climate and human activities. Taken as a whole, the results of this study present indispensable information for ecological and socio-economic research and may be used by scientists, landscape managers, and decision makers interested in this region.
Tropical rain forests are the most complex, varied, and species-rich terrestrial ecosystems on earth. However, these unique forests are more and more threatened by human activities. About half of the originally forested area has been deforested in the past decades and the pressure on today’s remaining rain forests is still growing.The German-Indonesian research project STORMA (“Stability of Rainforest Margins in Indonesia”) analyses the causes, circumstances, and consequences of rain forest conversion. In its survey area in Central Sulawesi (Indonesia), vast areas of intact rain forest still exist but are currently facing increasing exploitation by the rural population. Especially the expansion of cultivation area for cocoa and maize represents a major threat for local rain forests.Remote sensing plays an important role in the examination of rain forest loss, because it allows the regionalisation and quantification of spatial developments at different scales. In his book, Christian Knieper gains information about land cover and land cover change in Central Sulawesi on the basis of a Landsat 7/ETM+ time series. He applies a modern object-oriented approach which allows the analysis of non-spectral features (e.g. shape, spatial relations, thematic data) and goes beyond the pure isolated statistical examination of each pixel’s spectral values offered by traditional remote sensing techniques. The gathered results on land cover change provide essential information for socio-economic as well as ecological research activities within STORMA.
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.
Central Asia is a large and understudied region of varied geography, ranging from the high passes and mountains of Tian Shan, to the vast deserts of Kyzyl Kum, Taklamakan to the grassy treeles steppes. This region is faced with adverse conditions, as much of the land is too dry or rugged for farming. Additionally, the rich specific and intraspecific diversity of fruit trees and medicinal plants is threatened by overgrazing, oil and mineral extraction, and poaching. Countless species from the approximately 20 ecosystems and 6000 plant taxa are now rare and endangered. Traditional vegetation studies in this region are far from adequate to handle complex issues such as soil mass movement, soil sodicity and salinity, biodiversity conservation, and grazing management. However, data analysis using a Geographical Information System (GIS) tool provides new insights into the vegetation of this region and opens up new opportunities for long-term sustainable management. While vegetation planning can occur at a property scale, it is often necessary for certain factors, such as salinity, to be dealt with on a regional scale to ensure their effective management. GIS increases the effectiveness and accuracy of vegetation planning in a region. Such regional planning will also greatly increases biodiversity values. This book systematically explores these issues and discuses new applications and approaches for overcoming these issues, including the application of GIS techniques for sustainable management and planning. Professional researchers as well as students and teachers of agriculture and ecology will find this volume to be an integral resource for studying the vegetation of Central Asia.
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on Climate Change and Land (SRCCL) is the most comprehensive and up-to-date scientific assessment of the multiple interactions between climate change and land, assessing climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems. It assesses the options for governance and decision-making across multiple scales. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
This volume is a compilation of studies on interactions of changes in land cover, land use and climate with people, societies and ecosystems in drylands of Greater Central Asia. It explores the effects of collapse of socialist governance and management systems on land use in various parts of Central Asia, including former Soviet Union republics, Mongolia and northern drylands of China. Often, regional land-atmosphere feedbacks may have large global importance. Remote sensing is a primary tool in studying vast dryland territories where in situ observations are sporadic. State-of-the-art methods of satellite remote sensing combined with GIS and models are used to tackle science questions and provide an outlook of current changes at land surface and potential scenarios for the future. In 10 chapters, contributing authors cover topics such as water resources, effects of institutional changes on urban centers and agriculture, landscape dynamics, and the primary drivers of environmental changes in dryland environment. Satellite observations that have accumulated during the last five decades provide a rich time series of the dynamic land surface, enabling systematic analysis of changes in land cover and land use from space. The book is a truly international effort by a team of scientists from the U.S., Europe and Central Asia. It is directed at the broad science community including graduate students, academics and other professionals at all levels within natural and social sciences. In particular, it will appeal to geographers, environmental and social scientists, economists, agricultural scientists, and remote sensing specialists.
Greater Central Asia encompasses a vast area that includes deserts, natural grasslands, steppes, shrublands and alpine regions. Many of these land types are degraded and productivity is falling at a time when human populations and livestock inventories are on the rise. Ecosystem stability and biodiversity are under threat and there is an urgent need to develop more sustainable land management regimes. This book uses an integrated regional approach to provide a comprehensive exploration of sustainable land development in Central Asia. An interdisciplinary team of experts analyses the economic, ecological, sociological, technological and political factors surrounding sustainable land and water management in the region, sharing potential problems and solutions. As international concern about desertification grows, the book concludes by asking how the region is likely to develop in the future. This book will be of value to scholars, students, policy makers and NGOs with an interest in sustainable development in Central Asia.
The book attempts to match user need to the level of technology required for management, planning and monitoring of natural resources. It provides clear guidance on the reliability, accuracy and cost of applications. Editors believe that this endeavour shall provide a valuable scientific basis to students and researchers to address the future challenges in natural resources monitoring and management. Accurate inventory, assessment and periodic monitoring of resources will enable the policy makers to keep an eye on optimal utilization of resources and development process to take timely interventions. We further hope this book will be a valuable reference and provide practical guidance for all who work towards the goal of the sustainable and judicious use of resources.
Drylands in East Asia (DEA) are home to more than one billion people with an environment vulnerable to natural and anthropogenic changes. One of the critical needs in the region is to fully understand how dryland ecosystems respond to the changing climate and human activities in order to develop strategies to cope with continued climate change. This book provides state-of-the-art knowledge and information on drylands ecosystem dynamics, changing climate, society, and land use in the region. In addition to the synthesis of the existing research and knowledge of DEA, the book provides a role model for regional ecological assessment. With a wide spectrum of contributions from experts around the globe, the book should be of interest to researchers and students both internationally and in East Asia. Lessons learned from this synthesis effort in DEA should be useful for developing climate adaptation strategies for other similar regions around the globe.
