Human appropriation of net primary production (HANPP) in Nova Scotia, Canada

@article{citeulike:1225245, abstract = {Photosynthetically fixed energy from the sun, in the form of net primary production, ultimately supports the majority of life on earth. Given the importance of this energy source, we calculate the human appropriation of net primary production (HANPP) for the province of Nova Scotia, Canada. We find that over 25\% of potentially available production is appropriated by humans through harvest (forestry and agriculture) and land cover change. The level of appropriation in Nova Scotia is close to the global average, when methodological differences between studies are taken into account, but substantially less than in Austria and India where detailed surveys have also been conducted. Furthermore, HANPP is not distributed evenly throughout the province, but is instead concentrated in the north-central counties, where appropriation reaches 50\%. We discuss the implications of these results, and the novel method used to obtain them, in the context of biophysical assessment and the species-energy hypothesis.}, author = {O'Neill, Daniel and Tyedmers, Peter and Beazley, Karen }, citeulike-article-id = {1225245}, doi = {http://dx.doi.org/10.1007/s10113-006-0021-1}, issn = {1436-3798}, journal = {Regional Environmental Change}, keywords = {canada, npp}, month = {March}, number = {1}, pages = {1--14}, posted-at = {2007-07-19 12:13:11}, priority = {2}, publisher = {Springer}, title = {Human appropriation of net primary production (HANPP) in Nova Scotia, Canada}, url = {http://dx.doi.org/10.1007/s10113-006-0021-1}, volume = {7}, year = {2007} }
