Bibliographia Aethiopica II


Book Description

Erstmals wird hier die Fulle der englischsprachigen Athiopienliteratur geordnet dargeboten. In 100 Sections fuhrt der Autor alle fur die wissenschaftliche Beschaftigung mit Athiopien wichtigen Buch- und Zeitschriftenbeitrage zum Beispiel zur "Historyof Research", "Archaeology", "Religion", aber auch Fragen der "Sociology", "Agriculture", "Zoology" und "Medical Sciences" auf. Wie im Falle der deutschsprachigen Literatur ("Bibliographia Aethiopica: Die athiopienkundliche Literatur des deutschsprachigenRaumes" = Aethiopistische Forschungen 9 [1982]) berucksichtigt der Autor auch alle ihm zuganglichen Besprechungen, womit bei einer Aufnahme von mehr als 24.000 Titeln eine Art "Bibliographic Enzyclopedia" entstanden ist.




Quantitative Remote Sensing of Land Surfaces


Book Description

Processing the vast amounts of data on the Earth's land surface environment generated by NASA's and other international satellite programs is a significant challenge. Filling a gap between the theoretical, physically-based modelling and specific applications, this in-depth study presents practical quantitative algorithms for estimating various land surface variables from remotely sensed observations. A concise review of the basic principles of optical remote sensing as well as practical algorithms for estimating land surface variables quantitatively from remotely sensed observations. Emphasizes both the basic principles of optical remote sensing and practical algorithms for estimating land surface variables quantitatively from remotely sensed observations Presents the current physical understanding of remote sensing as a system with a focus on radiative transfer modelling of the atmosphere, canopy, soil and snow Gathers the state of the art quantitative algorithms for sensor calibration, atmospheric and topographic correction, estimation of a variety of biophysical and geoph ysical variables, and four-dimensional data assimilation




Rangeland Systems


Book Description

This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.




Landscape Dynamics, Soils and Hydrological Processes in Varied Climates


Book Description

The book presents the processes governing the dynamics of landscapes, soils and sediments, water and energy under different climatic regions using studies conducted in varied climatic zones including arid, semi-arid, humid and wet regions. The spatiotemporal availability of the processes and fluxes and their linkage to the environment, land, soil and water management are presented at various scales. Spatial scales including laboratory, field, watershed, river basin and regions are represented. The effect of tillage operations and land management on soil physical characteristics and soil moisture is discussed. The book has 35 chapters in seven sections: 1) Landscape and Land Cover Dynamics, 2) Rainfall-Runoff Processes, 3) Floods and Hydrological Processes 4) Groundwater Flow and Aquifer Management, 5) Sediment Dynamics and Soil Management, 6) Climate change impact on vegetation, sediment and water dynamics, and 7) Water and Watershed Management.







The Soils of Ethiopia


Book Description

This book addresses Ethiopia's extremely rich soil diversity and resources, which have developed under various climatic conditions. Featuring contributions by a group of respected experts on Ethiopian soils and agriculture, it provides comprehensive information on the management approaches needed for sustainable soil utilization and conservation under such conditions and the attendant challenges. It offers a valuable resource for anyone interested in soils and agriculture in Ethiopia, but also in other African countries with similar climatic conditions. The book contains 13 chapters which illustrate the long history of knowledge and soil research; climate; geology and geomorphology; soil forming factors, processes, and classification; major soil types, their properties, fertility status, and management; land evaluation and land use planning; soils and society/industry; and future/emerging soil issues.




Rainfed Agriculture


Book Description

This book, which contains 14 chapters, covers all aspects of rainfed agriculture, starting with its potential, current status, rainwater harvesting and supplementary irrigation, to policies, approaches, institutions for upscaling, and impacts of integrated water management programmes in rainfed areas.
