This book was released on 2015 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposed a methodological framework for the assessment of carbon stocks and the development and identification of land use, land use change and land management scenarios, whereby enhancing carbon sequestration synergistically increases biodiversity, the prevention of land degradation and food security through the increases in crop yields. The framework integrates satellite image interpretation, computer modelling tools (i.e. software customization of off-the-shelf soil organic matter turnover simulation models) and Geographical Information Systems (GIS). The framework addresses directly and indirectly the cross-cutting ecological concerns foci of major global conventions: climate change, biodiversity, the combat of desertification and food security. Their synergies are targeted by providing procedures for assessing and identifying simultaneously carbon sinks, potential increases in plant diversity, measures to prevent land degradation and enhancements in food security through crop yields, implicit in each land use change and land management scenario. The scenarios aim at providing quot;win-winquot; options to decision makers through the framework's decision support tools. Issues concerning complex model parameterization and spatial representation were tackled through tight coupling soil carbon models to GIS via software customization. Results of applying the framework in the field in two developing countries indicate that reasonably accurate estimates of carbon sequestration can be obtained through modeling; and that alternative best soil organic matter management practices that arrest shifting quot;slash-and-burnquot; cultivation and prevent burning and emissions, can be identified. Such options also result in increased crop yields and food security for an average family size in the area, while enhancing biodiversity and preventing land degradation. These options demonstrate that the judicious management of organic matter is central to greenhouse gas mitigation and the attainment of synergistic ecological benefits, which is the concern of global conventions. The framework is to be further developed through successive approximations and refinement in future, extending its applicability to other landscapes.
Download or read book Carbon Sequestration Potential of Agroforestry Systems written by B. Mohan Kumar and published by Springer Science & Business Media. This book was released on 2011-08-05 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree based production systems abound especially in the tropics. Despite the pervasiveness of such multipurpose “trees-outside-forest” resources, they have not attracted adequate attention in the development paradigms of many nation states. These multispecies production systems impact the ecosystem processes favourably. Yet, our understanding of the diversity attributes and carbon dynamics under agroforestry is not adequate. This book focuses on the role of multispecies production systems involving tree and crop species as a means for carbon sequestration and thereby reduce atmospheric carbon dioxide levels. Sixteen chapters organized into three broad sections titled: Measurement and Estimation, Agrobiodiversity and Tree Management, and Policy and Socioeconomic Aspects represent a cross section of the opportunities and challenges in current research and emerging issues in harnessing carbon sequestration potential of agroforestry systems.

Download or read book Managing Basin Interdependencies in a Heterogeneous Highly Utilized and Data Scarce River Basin in Semi Arid Africa written by Jeremiah Kipkulei Kiptala and published by CRC Press. This book was released on 2020-04-30 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.

Having three objectives the book first aims to give an interdisciplinary account of the drivers, consequences and challenges of ongoing changes in mountainous areas of Southeast Asia. Second, the book describes how innovation processes can contribute to addressing these challenges and third, how knowledge creation to support change in policies and institutions can assist in sustainably develop mountain areas and people’s livelihoods.
Download or read book Regional Environmental Life Cycle Assessment for Improving Food Chain Sustainability written by Pegah Amani and published by Springer. This book was released on 2019-02-02 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current LCA methodologies employed to assess the intensity of environmental impacts lack a regional view, even though the sensitivity of the receiving environment is important in determining the specific levels of risks. This book seeks to redress the balance and develop a globally applicable, affordable and feasible approach to determine differentiated sets of possible impacts with higher environmental burdens derived from food supply chain processes. To this end, the earth’s land surface is divided into so-called “ecoregions”, defined by their specific characteristics such as soil, climate, and topography/physiography, and associated with the relevant risks for each ecoregion. The use of ecoregions and respective environmental risks can help enterprises recognize the environmental effect of their products but also help improve the reliability of comparisons between LCA results in different regions.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report outlines the progress on the development and application of Integrated Assessment Modeling of Carbon Sequestrations and Land Use Emissions supported by the DOE Office of Biological and Environmental Research (OBER), U.S. Department of Energy, Grant No. DOE-DE-FG02-01ER63069. The overall objective of this collaborative project between the University of Illinois at Urbana-Champaign (UIUC), Oak Ridge National Laboratory (ORNL), Lawrence Livermore National Laboratory (LLNL), and Pacific Northwest National Laboratory (PNNL) was to unite the latest advances in carbon cycle research with scientifically based models and policy-related integrated assessment tools that incorporate computationally efficient representations of the latest knowledge concerning science and emission trajectories, and their policy implications. As part of this research we accomplished the following tasks that we originally proposed: (1) In coordination with LLNL and ORNL, we enhanced the Integrated Science Assessment Model's (ISAM) parametric representation of the ocean and terrestrial carbon cycles that better represent spatial and seasonal variations, which are important to study the mechanisms that influence carbon sequestration in the ocean and terrestrial ecosystems; (2) Using the MiniCAM modeling capability, we revised the SRES (IPCC Special Report on Emission Scenarios; IPCC, 2000) land use emission scenarios; and (3) On the application front, the enhanced version of ISAM modeling capability is applied to understand how short- and long-term natural carbon fluxes, carbon sequestration, and human emissions contribute to the net global emissions (concentrations) trajectories required to reach various concentration (emission) targets. Under this grant, 21 research publications were produced. In addition, this grant supported a number of graduate and undergraduate students whose fundamental research was to learn a disciplinary field in climate change (e.g., ecological dynamics and ocean circulations) and then complete research on how this field could be linked to the other factors we need to consider in its dynamics (e.g., land use, ocean and terrestrial carbon sequestration and climate change).
Download or read book Soil Processes and the Carbon Cycle written by Rattan Lal and published by CRC Press. This book was released on 2018-02-06 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.
Download or read book Carbon Sequestration in Agricultural Soils written by Alessandro Piccolo and published by Springer Science & Business Media. This book was released on 2012-01-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation of techniques, methodologies and scientific data arises from a four-year Italian research project, which took place at university research stations in Turin, Piacenza, Naples and Potenza. Soil Organic Matter (SOM) represents an active and essential pool of the total organic carbon on the planet. Consequently, even small changes in this SOM carbon pool may have a significant impact on the concentration of atmospheric CO2. Recent new understanding of the chemical nature of SOM indicates that innovative and sustainable technologies may be applied to sequester carbon in agricultural soils. Overall results of the project have been applied to develop an innovative model for the prediction and description, both quantitatively and qualitatively, of carbon sequestration in agricultural soils. This book provides experts in different areas of soil science with a complete picture of the effects of new soil management methods and their potentials for practical application in farm management.
