Book Synopsis Desertification and Risk Analysis Using High and Medium Resolution Satellite Data by : Alberto Marini
Download or read book Desertification and Risk Analysis Using High and Medium Resolution Satellite Data written by Alberto Marini and published by Springer Science & Business Media. This book was released on 2008-11-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work becomes with methodological rigor a part of the innovative proposals for the characterization of the areas at risk of desertification. The complexity of the phenomenon of desertification, which involves extended surfaces in all continents, is one of the most alarming processes of the environmental degradation of our Planet and threatens the health and the living conditions of over a billion of persons. The food crisis, in continuous increase, ask for the world of research to urgently supply reassuring solutions concerning the acquisition of indicators, which are easy to monitor and concur to control the phenomenon in order to fight its acceleration. The constant but different combination that determines the diffusion of deserti- cation in the territories, attributable mostly to climatic changes and the activities of the man, makes our job challenging and complicated, since it varies from region to region. We are aware of all this and therefore we think that the methodological approach of survey of the data is an extremely important element to locate of the phenomenon and to monitor its course. This work, which is characterized for its multi-disciplinary approach, suggests solutions that we wish will quickly find concrete applications at international level.

Book Synopsis Arid Land Ecosystems: Volume 2, Structure, Functioning and Management by : D. W. Goodall
Download or read book Arid Land Ecosystems: Volume 2, Structure, Functioning and Management written by D. W. Goodall and published by Cambridge University Press. This book was released on 2009-03-19 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume was first published in 1981. The history of man's use of arid lands is a sad record of deterioration of the natural resource base and of low and declining living standards for the 300 million people who live in them. One prerequisite to meeting the challenge of reversing the deterioration and of raising living standards is a sound knowledge of the natural ecosystems.
Book Synopsis Thematic Mapping from Satellite Imagery by : J. Denègre
Download or read book Thematic Mapping from Satellite Imagery written by J. Denègre and published by Elsevier. This book was released on 2013-10-22 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report, produced between 1984 and 1987 in a bilingual edition (English and French), provides a wealth of information on a wide variety of cartographic applications which are being developed to make effective use of new data that is now being collected by Earth observation satellites. At a time when natural resource development and environmental problems have to be taken into account in their entirety, satellites provide an exceptional means of evaluating, synthesizing and creating geographic information. The production of new images, such as the Landsat Thematic Mapper, the SPOT High Resolution Visible Sensor and the adoption meteorological images such as AVHRR sensors on NOAA satellites, which have been extended to thematic domains such as agriculture and glaciology, have led to many new developments as well as problems for the cartographer. These problems are numerous and varied and recur frequently depending on the images and themes being processed e.g. how to select the graphic specification of maps and legends and account for classification accuracy; how to introduce the minimum of topographical data into an image in order to supply users with an adequate geographic reference; when using a physical terrain image, on which, by definition there are no `blanks' and where no details have been eliminated, how to overcome conceptual difficulties e.g. the side by side placing of different semiological information; the interpretation levels left to reader; achieving a balance between objectivity and readability. Obviously the cartographers role is of prime importance in solving these problems. In order to illustrate the way in which this information is presented, the report provides samples from 33 thematic applications taken from 13 different categories, including agriculture, town planning and water resources. Each application is provided with a descriptive note both in English and French indicating the objective, method and results obtained. This volume provides an important record of current developments in thematic mapping from satellite imagery and should be essential reference for all cartographers.
Book Synopsis Crop Yield Response to Deficit Irrigation by : C. Kirda
Download or read book Crop Yield Response to Deficit Irrigation written by C. Kirda and published by Springer Science & Business Media. This book was released on 1999 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses general concept and management issues of deficient irrigation practices, covering a wide range of field crops including cotton, maize, soybean, wheat, sugarcane, and the like, based on five years of field research implemented in fourteen different countries, in Latin America, Africa, Europe and Asia. Additionally, guidelines are given for experimental methodology and data analysis for evaluating crop yield response to deficient irrigation. Experimental data, discussions and cited references will be an asset not only to field irrigation engineers but also to research scientists including soil and irrigation scientists and agronomists, for whom the book would be an invaluable reference source.
Book Synopsis Rainwater harvesting technologies in the Sahelian zone of West Africa and the potential for outscaling by : Barry, Boubacar
Download or read book Rainwater harvesting technologies in the Sahelian zone of West Africa and the potential for outscaling written by Barry, Boubacar and published by IWMI. This book was released on 2009-05-11 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In West Africa, especially in the Sahelian countries of Burkina Faso, Niger, Mali and Mauritania, erratic rainfall sequences within and between years has often led to a high uncertainty in rainfed crop production. Over the past three decades, severe food shortages attributed to drought have been frequently reported in several Sahelian countries, most of which are amongst the least developed of the world. Innovative and indigenous ways to achieve improved crop yields through integrated land and water management such as rainwater harvesting and soil water conservation have been successfully tested and, in some cases, adopted in West Africa. This paper highlights the successful interventions of improved indigenous rainwater harvesting/soil water conservation technologies such as Zaï or tassa, stone rows and half-moon in the Sahelian zones of West Africa over the past 10 years, and their contributions to enhancing food security and alleviating poverty. The potential for adoption of these technologies at the farm level and their outscaling to areas with similar agroecological zones are also discussed.

Book Synopsis Groundwater Recharge from Run-off, Infiltration and Percolation by : K.-P. Seiler
Download or read book Groundwater Recharge from Run-off, Infiltration and Percolation written by K.-P. Seiler and published by Springer Science & Business Media. This book was released on 2007-09-26 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: To face the threats to the water supply and to maintain sustainable water management policies, detailed knowledge is needed on the surface-to-subsurface transformation link in the water cycle. Recharge flux is covered in this book as well as many other groundwater issues, including a comparison of the traditional and modern approaches to determine groundwater recharge. The authors also explain in detail the fate of groundwater recharge in the subsurface by hydraulic and geologic means, in order to stimulate adapted groundwater-management strategies.
