Book Description
With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be double

Book Description
Changing land-use practices and the role of soil biological diversity has been a major focus of soil science research over the past couple of decades—a trend that is likely to continue. The information presented in this book points to a holistic approach to soil management. The first part looks at the land use effects on soil carbon storage, and considers a range of factors including carbon sequestration in soils. The second part of the book presents research investigating the interactions between soil properties, plant species, and the soil biota.

Book Description
Ayla Neusel The idea of holding an International Women's University ifu as part of the EXPO 2000'W orld Exposition was born in Lower Saxony in the mid-1990s. In 1992, Lower Saxony's then Minister of Science Helga Schuchardt had set up a Women's Research Commission that in 1994 presented its report with the programmatic title "Promoting Women's Interests Means Academic Reform - Women's Research Means a Critique of Science". A spin-off, so to speak, of this commission's was nd the idea of a women's university as an EXPO project. The 2 Lower Saxony Women's Research Commission (1995-1997) stated: "From 15 July until 15 Oc­ tober, an International Women's University is to be Q~ganised offering an interdis­ ciplinary, international, multimedia, postgraduate study programme". Initially conceived as a purely research-oriented university, ijiJ evolved into an academic project for women scientists on an international scale. The ifu concept was based on the (self-) image of science as an ongoing, evolving, forward­ looking research project. The unique concept of the International Women's University as an academic reform project was founded on three key principles: 1. Problem Orientation of Teaching and Research The choice of the globally relevant controversial issues Work - Information - Body - Migration - City - Water and the idea of addressing these issues from the perspective of the natural and engineering sciences, the humanities and so­ cial sciences as well as art, consciously focusing on questions of practical rele­ vance, gave rise to a problem-oriented, interdisciplinary approach.

Book Description
With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Book Description
Sustainable Water Resource Development and Management is a comprehensive volume on this important topic. It broadly covers the sources, availability, demand, and supply of water and its uses in irrigation and crop production in agriculture. It then delves into many specific aspects of water resource development and management, including Irrigation creation and utilization Water storage efficiency, conveyance efficiency, distribution efficiency, and application efficiency The role of water in plant systems and soil-water-plant relationships Estimating the water need for irrigation along with management strategies Water quality in agriculture as well as the impact of water quality on human health Water pricing Wetland management and water productivity Water pollution in agriculture and water contamination in urban and rural areas Examples and case studies are included to illustrate and reinforce the text, such as reviews of river linking projects, adopted water management technologies for agricultural farms, important irrigation projects (both minor and major), and more.Written by two eminent researchers and scientists in agricultural water management, this informative volume is designed for students of agriculture, researchers, policymakers, and teachers engaged in the field of water management.
