The first two criteria served as a 'screen' since only candidate indicators which reflected serious sustainability concerns and could be significantly influenced by policy steps are relevant to assessments of environmental sustainability, regardless of their other merits. In terms of the study, we found it necessary to employ a second screen, the data availability. Since the project lacks funding for major new data collection and analysis, the measures actually evaluated during the course of this project must be ones for which the data already are available. Geometric Mean is a term, which is the result of a statistical method used to manipulate data with large fluctuation. 2 Eutrophication is a term used to describe the nutrient enrichment process within a water body that has an originally poor nutrient level.
Serious eutrophication can cause water quality deterioration.
A Chinese project overview will follow soon.
