Why do technically sound WASH sector strategies, even those that have been successful in other contexts or constitute accepted ‘best practice’, fail to improve access to water supply and sanitation, especially for the poor? Why do good sector policies, often supported by donor technical assistance, fail to get implemented? Why are seemingly successful pilot programmes not scaled up? Why are sec...

We attempt to quantify how significant the polar archipelago of South Georgia is as a source of regional and global marine biodiversity. We evaluate numbers of rare, endemic and range-edge species and how the faunal structure of South Georgia may respond to some of the fastest warming waters on the planet. Biodiversity data was collated from a comprehensive review of reports, papers and databas...

In this study, seven walnut populations (Rabor, Hanza, Sardoueih, Dalfard, Bidkhan, Dehbakri, and Baft) were selected from Kerman province and compared for drought stress tolerance. Water potential between 0 and -1.5 MPa was obtained by polyethylene glycol 6000 solutions. Germination percentage, leaf relative water content (LRWC), and growth parameter of seedlings diminished with increasing dro...

The SOS/umuC assay was performed in conjunction with analytical measurements to identify potential genotoxins in river and adjacent ground waters in the Jialu River basin, China. The major genotoxic activities of the river and adjacent ground waters occurred in the same two fractions (F4 and F11) when assayed using the Salmonella typhimurium strain TA1535/pSK1002. This indicates that ground wat...

The European Community Green Paper on Future Noise Policy (1996) recognised that environmental noise is “one of the main local environmental problems in Europe” but that it has had a lower priority than other environmental problems, such as air or water pollution. It also recognised that, despite significant reductions in the noise produced by individual sources, total exposure to environmental...

This paper introduces a series of 6 additional papers in this issue that describe an in-depth analysis of options for decommissioning oil and gas platforms offshore southern California. Although current leases require lessees in both state and federal waters to completely remove all production facilities and restore the seafloor to its pre-platform condition, other options have emerged since th...
