Cities are constantly migrating and metabolizing, leaving behind industrial legacy and environmental degradation to be remediated by future generations; legacies of toxic waste, polluted ground waters, sealed soils, powsy land and degraded ecosystems.
After evaluating seven factors expected to affect soil biodiversity (land-use change, organic carbon loss, agriculture/land-use intensity, soil erosion, soil compaction and sealing, soil pollution and soil acidification), we quantified and mapped the composite threats to soil biodiversity in Nanjing using a weighted sum method.
But that year, on the eve of an international trade conference, the medina underwent a beautification program, which included pulling up vegetation and sealing the soil with cement tiles.
If we are not sealing the soil down with concrete, we are allowing the wind and rain to wash it into the oceans.
Since we can not rule out that sealing the soil with agar increased the relative fluxes of methane that were emitted through the plants (instead of through the soil), we note that this method shows the potential for the plants to act as conduits but possibly not the real importance in the actual soil-plant system.
Per-capita sealed land, a landscape conservation index and selected territorial variables were considered into a multivariate exploratory framework aimed at assessing the correlation between land-use efficiency (based on the degree of soil sealing per-capita) and the quality of suburban landscape.
Dynamics of soil sealing and soil landscape patterns under rapid urbanization were qualified in the Urban Agglomeration around Hangzhou Bay (UAHB), China.
The dynamics of soil sealing and soil landscape patterns not only reflected common tendencies in China, but represented a global process.
A longtime East Hampton resident, Mr. Norklun has seen it all: dogs biting joggers, attacking birds, killing a seal, soiling on people and their belongings.
After its closure in 1981, it was sealed with soil and planted over with Grasslands and trees.
