Carbon stored in soils represents the largest terrestrial carbon pool and factors affecting this will be vital in the understanding of future atmospheric CO2 concentrations. This book provides an integrated view on measuring and modeling soil carbon dynamics. Based on a broad range of in-depth contributions by leading scientists it gives an overview of current research concepts, developments and outlooks and introduces cutting-edge methodologies, ranging from questions of appropriate measurement design to the potential application of stable isotopes and molecular tools. It includes a standardised soil CO2 efflux protocol, aimed at data consistency and inter-site comparability and thus underpins a regional and global understanding of soil carbon dynamics. This book provides an important reference work for students and scientists interested in many aspects of soil ecology and biogeochemical cycles, policy makers, carbon traders and others concerned with the global carbon cycle.

Biochar, a biomass that is burned at very high temperature in the absence of oxygen, has recently become an interesting subject of study. Biochar is highly stable and does not degrade; it possesses physical properties that assist in retention of nutrients in the soil. The use of biochar will undoubtedly have a significant impact not only on soil nutrients but also on soil organism communities and their functions. This book focuses on how the ecology and biology of soil organisms is affected by the addition of biochar to soils. It takes into account direct and indirect effects of biochar addition to soils, on the soil carbon cycle, impact on plant resistance to foliar and soilborne disease, interactions with pathogenic, mycorhizal and saprophytic fungi. The stability of biochar in soil environment is also discussed. Special focus has been put on application of biochar to remediate polluted soils, taking into account possible toxic effects of biochar on soil fauna. This book will be useful to students and researchers in agronomy, biology, ecology, and environmental managers from both academic as well as industrial organizations.

A comprehensive book on basic processes of soil C dynamics and the underlying factors and causes which determine the technical and economic potential of soil C sequestration. The book provides information on the dynamics of both inorganic (lithogenic and pedogenic carbonates) and organic C (labile, intermediate and passive). It describes different types of agroecosystems, and lists questions at the end of each chapter to stimulate thinking and promote academic dialogue. Each chapter has a bibliography containing up-to-date references on the current research, and provides the state-of-the-knowledge while also identifying the knowledge gaps for future research. The critical need for restoring C stocks in world soils is discussed in terms of provisioning of essential ecosystem services (food security, carbon sequestration, water quality and renewability, and biodiversity). It is of interest to students, scientists, and policy makers.

A fundamental requirement of Agenda 21 of UNCED is to support sustainable development while safeguarding the Earth's environment. This requires optimal management of natural resources which depends on the availability of reliable and timely information at the global, national, regional and local scales. One such technology, "Geoinformatics", consisting of Remote Sensing (RS), Geographical Information System (GIS), and Global Positioning System (GPS) is source of reliable and timely information needed for natural resource management, environmental protection and addressing issues related to sustainable development. It offers a powerful tool for resource assessment, mapping, monitoring, modelling, management etc. It is also capable to make use of recent developments in the digital integration of human reasoning, data and dynamic models. These tools have been available for past three decades. Many institutions and organisations are carrying out various research and operational applications of direct relevance particular to natural resource management. However, there are still limitations in understanding the underlying science and research elements, as there are larger questions of capacity building to use geoinformatics in natural resource management and associated sustainable development applications. These programs also find gaps between the theoretical concepts and the operational utilisation of these tools. This could be solved by providing wide range of applications and prospective potential of this technology to the students and research community in this area. "Geoinformatics for Natural Resource Management" contains chapters written by noted researchers and experts. The focus emerged with filling a gap in the available literature on the subject by bringing together the concepts, theories and experiences of the experts in this field.

Carbon Sequestration And Its Role In The Global Carbon Cycle

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 183. For carbon sequestration the issues of monitoring, risk assessment, and verification of carbon content and storage efficacy are perhaps the most uncertain. Yet these issues are also the most critical challenges facing the broader context of carbon sequestration as a means for addressing climate change. In response to these challenges, Carbon Sequestration and Its Role in the Global Carbon Cycle presents current perspectives and research that combine five major areas: The global carbon cycle and verification and assessment of global carbon sources and sinks Potential capacity and temporal/spatial scales of terrestrial, oceanic, and geologic carbon storage Assessing risks and benefits associated with terrestrial, oceanic, and geologic carbon storage Predicting, monitoring, and verifying effectiveness of different forms of carbon storage Suggested new CO2 sequestration research and management paradigms for the future. The volume is based on a Chapman Conference and will appeal to the rapidly growing group of scientists and engineers examining methods for deliberate carbon sequestration through storage in plants, soils, the oceans, and geological repositories.

This book provides a comprehensive yet accessible overview of landsystems vulnerability assessment in Asia - fundamental to theunderstanding of the link between global change, environmentalsustainability and human wellbeing. The extent and intensity ofhuman interactions with the environment have increasedspectacularly since the Industrial Revolution. Thus, the globalchange research community and development practitionersincreasingly recognize the need to address the adverse consequencesof changes taking place in the structure and function of thebiosphere and the implications for society. With a focus onAsia, this book provides an overview of the vulnerability of landsystems and the subsequent multiple stressors in this region. Thebook offers a discussion surrounding the potential causal processesthat affect land systems vulnerability and our capacity to copewith different perturbations. It also identifies factors that helpto integrate vulnerability assessment into policy anddecision-making. • Addresses the complex issues arising fromhuman–environment interactions that cannot be satisfactorilydealt with by core disciplinary methods alone. • Key coverage of a variety of topics from thevulnerability of smallholder agriculture and urban systems to theimpact of socioeconomic processes at the sub-regional level. • Coverage of the causal processes that affect landsystems vulnerability and capacity to cope with differentperturbations are documented. • Focus on integrating vulnerability assessment intopolicies and decision-making • Includes contributions from leading academics in thefield.
