With immense pleasure we announce launching of Natural Products and Resources Repository (NPARR) with open access...
Coffee can be cultivated under various management schemes from heavy shade to full sun. Higher yields are generally achieved in full sun but often at the expense of smaller beans and greater requirements for water and nutrients. We compared growth, yield, bean size, and total value in a coffee agroecosystem in Hawaii grown in full sun or at two shade levels (30 and 50%) under Leucaena variety K...
Local and regional environments have for many centuries been seen as, or as being composed of, ''natural resources,'' which have generally been considered fully available for human use, irrespective of any use to which other species, purposefully or not, might put them.

Shale gas is currently being explored in Europe as an alternative energy source to conventional oil and gas. There is, however, increasing concern about the potential environmental impacts of shale gas extraction by hydraulic fracturing (fracking). In this study, we focussed on the potential impacts on regional water resources within the Baltic Basin in Poland, both in terms of quantity and qua...
Water, among the most valuable natural resources available on earth, is under serious threat as a result of undesirable human activities: for example, marine dumping, atmospheric deposition, domestic, industrial and agricultural practices.
