Sustaining Soil Productivity in Response to Global Climate Chan ge: Science, Policy, and Ethics is a multi-disciplinary volume exploring the ethical, political and social issues surrounding the stewardship of our vital soil resources. Based on topics presented by an international group of experts at a conference convened through support of the Organization for Economic Co-operation and Development, chapters include scientific studies on carbon sequestration, ecosystem services, maintaining soil fertility, and the effects of greenhouse gas emissions, as well as ethical issues ranging from allocation of land use to policies needed for climate change adaptation and mitigation.
Bringing together the latest research in soil science and climatology, Sustaining Soil Productivity in Response to Global Climate Change is a valuable resource for soil and plant scientists, agronomists and environmental scientists, as well as agricultural and natural resources engineers and economists, environmental policy makers and conservationists.
Key Features:
Written by an international group of authors representing a cross-section of scientists, thought leaders, and policy-makers Includes chapters on the potential effects of climate change on forest soil carbon, microbial function, and the role of soils and biogeochemistry in the climate and earth system Explores historical development of land use ethics and stewardship
