Less than a half century ago, China experienced a cataclysmic famine, which was particularly devastating in the countryside. As a result, older people in rural areas have experienced in their lifetimes both extreme deprivation and relative abundance of food. Young people, on the other hand, have a different relationship to food. Many young rural Chinese are migrating to rapidly industrializing cities for work, leaving behind backbreaking labor but also a connection to food through agriculture. Bitter and Sweet examines the role of food in one rural Chinese community as it has shaped everyday lives over the course of several tumultuous decades. In her superb ethnographic accounts, Ellen Oxfeld compels us to reexamine some of the dominant frameworks that have permeated recent scholarship on contemporary China and that describe increasing dislocation and individualism and a lack of moral centeredness. By using food as a lens, she shows a more complex picture, where connectedness and sense of place continue to play an important role, even in the context of rapid change.
This 1991 volume presents the results of a major study of the mechanism and consequences of surface water acidification. It provides an overview of the chemical process involved in acidification and of its biological impact on freshwater life. The surface waters acidification programme (SWAP) has drawn together the many facets of this complex phenomenon.
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.
Since the late 1970s, China has undergone perhaps the most sweeping process of urbanization ever witnessed. This is typically understood as a story of growth, encompassing rapid development and economic dynamism alongside environmental degradation and social dislocation. However, over the past decade, China’s leaders have claimed that the country’s urbanization has entered a new stage that prioritizes “quality.” What does China’s new urban vision entail, and what does the future hold in store? Richard Hu unpacks recent trends in urban planning and development to explore the making and imagining of the contemporary Chinese city. He focuses on three key concepts—the “green revolu...
This book highlights the likely impacts of climate change in terms of global and national water securities, how different countries are attempting to address these complex problems and to what extent they are likely to succeed. A major global concern at present, especially after the social and economic havoc that has been caused by COVID-19 in only one year, is how we can return to earlier levels of economic development patterns and then further improve the process so that sustainable development goals are reached to the extent possible by 2030, in both developed and developing countries. Mankind is now facing two existential problems over the next several decades. These are climate change a...
Polymer-supported organic catalysts are largely insoluble in most reaction solvents, which allows for easy recovery and recycling of the catalysts. They are generally stable, readily available, and environmental friendly, so they have attracted the interest of many synthetic chemists in the industrial and academic fields. In this book, different types of polymer-supported catalysts based on peptides, polystyrene, polyethers, poly(acrylic acid), poly(ethylene imine), poly(2-oxazoline), poly(isobutylene), poly(norbornene), etc., as well as metals are included with their synthetic organic synthesis applications. It is believed that this work will be of interest to organic chemists, material scientists, chemical engineers, polymer scientists and technologists.
