Available water capacity Available water capacity is the soil water content within a range between field capacity and wilting point. It is the soil water content that can be retained in the soil and is available for plants. Confined groundwater Confined groundwater is the counterpart of phreatic groundwater or unconfined groundwater. It refers to the groundwater stored in confined aquifers, which are overlain by a confining layer made up of low permeability materials such as clay. Ecological civilization Ecological civilization is a term that describes a new stage of the development of human civilization. It represents a new stage of civilization following industrial civilization and is the final goal of an environmental reform within a given society. Ecological civilization can be described as the sum of all material and ideological achievements obtained by employing strategies for a harmonious development of the human society and the environment. It involves a synthesis of economic, educational, political, agricultural, and other societal reforms toward sustainability. Field capacity Field capacity is the amount of soil moisture or water content
Geologic Carbon Sequestration as a Global Strategy to Mitigate CO 2 Emissions: Sustainability and Environmental Risk Curtis M. Oldenburg Earth Sciences Division Lawrence Berkeley National Laboratory Berkeley, CA 94720 Glossary Carbon dioxide capture and storage (CCS) - The capture of CO 2 from fossil-fuel power plants and other industrial point sources and its injection through wells into deep geologic formations for permanent storage. Consequence - An impact arising from the occurrence of an event or process. For example, the consequence of high CO 2 concentrations in the atmosphere is global warming. Geologic carbon sequestration (GCS) = Geologic CO 2 storage (GCS) - The last step of CCS in which CO 2 is injected through wells into deep subsurface formations for permanent storage. Hazard - A potential impact or consequence of an event or process. For example, high CO 2 emissions are a hazard to climate because CO 2 is a greenhouse gas. Likelihood - The probability or degree of potential for an event or process to occur. For example, the likelihood of CO 2 emissions to increase is very high given population growth and worldwide increases in standard of living.
