Developed for Introduction to Soils or Soil Science courses, The Nature and Properties of Soils, 15th Edition, can be used in courses such as Soil Fertility, Land Resources, Earth Science and Soil Geography. The Nature and Properties of Soils is designed to engage today's students with the latest in the world of soils. This hallmark text introduces students to the exciting world of soils through clear writing, strong pedagogy, and an ecological approach that effectively explains the fundamentals of soil science. Worked calculations, vignettes, and current real-world applications prepare readers to understand concepts, solve problems, and think critically. Written for both majors and non-majors, this text highlights the many interactions between the soil and other components of forest, range, agricultural, wetland and constructed ecosystems. Now in full-colour, the 15th Edition includes hundreds of compelling photos, figures, and diagrams to bring the exciting world of soils to life. Extensively revised, new and updated content appears in every chapter. Examples include: coverage of the pedosphere concept; new insights into humus and soil carbon accumulation; subaqueous soils, soil effects on human health; principles and practice of organic farming; urban and human engineered soils; new understandings of the nitrogen cycle; water-saving irrigation techniques; hydraulic redistribution, soil food-web ecology; disease suppressive soils; soil microbial genomics; soil interactions with global climate change; digital soil maps; and many others.

How do rural Chinese households deal with the conflicting pressures of migrating into cities to work as well as staying at home to preserve their fields? This is particularly challenging for rice farmers, because paddy fields have to be cultivated continuously to retain their soil quality and value. Drawing on ethnographic fieldwork and written sources, Rural-Urban Migration and Agro-Technological Change in Post-Reform China describes farming households' strategic solutions to this predicament. It shows how, in light of rural-urban migration and agro-technological change, they manage to sustain both migration and farming. It innovatively conceives rural households as part of a larger farming community of practice that spans both staying and migrating household members and their material world. Focusing on one exemplary resource - paddy fields - it argues that socio-technical resources are key factors in understanding migration flows and migrant-home relations. Overall, this book provides rare insights into the rural side of migration and farmers' knowledge and agency.

Globalisation of the world economy portends a wide range of benefits to citizens of all countries. However, this ground-breaking book finds that the impacts of trade liberalisation and globalisation appear to have a negative impact on agricultural sustainability in developing countries.This book explores the proposition that globalisation and trade liberalisation is an international win-win game and finds that there is substantial evidence to suggest that there could be a range of agricultural problems and negative impacts on rural communities and the environment in poorer countries. The authors use cutting-edge research from Brazil, Bolivia, Burkino Faso, Indonesia, The Philippines and Thailand to suggest that special attention needs to be paid to local issues in poor countries in the face of globalisation. Sustainable Agriculture and Environment will prove invaluable to scholars and policymakers in the areas of environmental and ecological economics.
