Abstract

Five of the top ten problems facing humanity (http://cnst.rice.edu/content.aspx?id=246) over the next 50 years (food, water, energy, environment and poverty) are directly related to the health of soil resources. Several different factors, including: (a) excessive tillage; (b) inappropriate crop rotations; (c) excessive grazing or crop residue removal; (d) deforestation; (e) mining and/or fracking; and (f) construction or urban sprawl, have contributed to the global problem of soil degradation. Understanding and implementing sustainable agricultural and land management practices that improve soil health is essential for mitigating and reversing these trends, if we are to successfully meet the needs of more than 9.5 billion people who will be sharing our fragile planet by the middle of the 21st century.The overall focus for this Special Issue was on agricultural factors contributing to soil degradation and suggested strategies for mitigating and reversing those trends. The discussion was anchored by invited contributions reflecting perspectives from Africa, Australia, China, Eastern Europe, India, Latin America, North America, Russia, and Western Europe. Voluntary contributions were evaluated, and incorporated into the issue to provide a global perspective on soil degradation and strategies to mitigate its devastating effects.This Special Issue draws upon published literature addressing soil quality and/or soil health, soil and crop management strategies to mitigate soil degradation, and future research needs and strategies that will steadily improve the fragile layer that lies between us and starvation. Your participation and contributions to this important endeavor were most welcome.

Abstract

Human needs like food and clean water are directly related to good maintenance of healthy and productive soils. A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources. This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency. It is important to keep in mind that both soil and water are limited resources. Thus, wise use of these natural resources is a fundamental prerequisite for the sustainability of human societies. This book collects 15 original scientific contributions addressing the state of the art of soil and water conservation research. Contributions cover a wide range of topics, including (1) recovery of soil hydraulic properties; (2) erosion risk; (3) novel modeling, monitoring and experimental approaches for soil hydraulic characterization; (4) improvement of crop yields; (5) water availability; and (6) soil salinity. This collection provides more insights into conservation strategies for effective and sustainable soil and water management.

Abstract

One of the major knowledge challenges in the domain of Resilient and Sustainable Food Systems refers to the integration of perspectives on consumption, patterns that support public health, inclusive value chains, and environmentally sustainable food production. While there is a long record of the analysis of separate interventions, this special issue generates integrated insights, provides cross-cutting perspectives, and outlines practical and policy solutions that address these global challenges.The collection of papers promotes the view that sustainable food systems require thorough insights into the structure and dynamics of agri-food production systems, the drivers for integrating food value chains and markets, and key incentives for supporting healthier consumer choices. On the production side, potential linkages between agricultural commercialization and intensification and their effects for food security and nutritional outcomes are analyzed. Value Chains are assessed for their contribution to improving exchange networks and markets for food products that simultaneously support efficiency, circularity, and responsiveness. Individual motives and market structures for food consumption need to be understood in order to be able to outline suitable incentives to enhance healthy dietary choice.The contributed papers focus on interfaces between food system activities and processes of adaptive change that are critical for overcoming key constraints and trade-offs between sustainable food and healthy diets.
