Soil health, along with water supply, is the most valuable resource for humans, as human life depends on the soil’s generosity. Soil degradation, therefore, poses a threat to food security, as it reduces yield, forces farmers to use more inputs, and may eventually lead to soil abandonment. Unfortunately, the importance of preserving soil health appears to be overlooked by policy makers. In this...

Construction of coastal ports makes port area and nearby sea area become high risk region of ecological emergency and environmental pollution. It is helpful for providing references to protect ecological environment of port by quantifying port ecological carrying capacity. This paper will transfer resources and energy consumed in port production and operation to four ecological productive lands...

Agricultural Census data is summarised over spatially course reporting units for reasons of farm confidentiality. This is problematic for research at a local level. This paper describes an approach combining dasymetric and volume preserving techniques to create a national land use dataset at 1km resolution. The results for an English county are compared with contemporaneous aggregated habitat d...
