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
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
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
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
Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.

Book Description
Taking a sustainable approach, this volume explores the various soil management techniques. It begins with an overview of the elementary concepts of soil management and then delves into new research and novel soil management tools and techniques. Topics include: • Clays as a critical component in sustainable agriculture with respect to carbon sequestration in conjunction with its interaction with soil enzymes • The potential utilization of microbes to mitigate crop stress • Resource conservation technologies and prospective carbon management strategies • The use of smart tools for monitoring soils • Effective nutrient management approaches • Nanotechnological interventions for soil management • Techniques for the remediation of soils contaminated by metals and pesticides

Book Description
This book includes twenty-one comprehensive chapters addressing various soil and crop management issues, including modern techniques in enhancing crop production in the era of climate change. There are a few case studies and experimental evidence about these production systems in specific locations. Particular focus is provided on the state-of-the-art of biotechnology, nanotechnology, and precision agriculture, as well as many other recent approaches in ensuring sustainable crop production. This book is useful for undergraduate and graduate students, teachers, and researchers, particularly in the fields of crop science, soil science, and agronomy.
