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...

On August 18, 2002, the Hyperion hyperspectral imager onboard the EO-1 platform recorded data over an intensively used agricultural area in north western Switzerland, the Limpach Valley. The sensor’s 198 spectral bands between 400 and 2500 nm (Level 1B1) and a spatial resolution of 30 m bear the potential for both a detailed land use classification and an accurate estimation of biophysical and ...

The expensive nature of metal ions detoxification from wastewater have restricted the use of conventional treatment technologies. Cheap, alternative measures have been adopted to eliminate metal contamination, and adsorptions using agricultural adsorbents seem to be the way forward. The use of agricultural adsorbents for cadmium (II), copper (II) and lead (II) ion removal has gained more intere...
