Risk prioritisation of stormwater pollutant sources

This paper describes the development of a pollutant risk prioritisation methodology for the comparative assessment of stormwater pollutants discharged from differing land use types and activities. Guidelines are presented which evaluate available data with respect to ‘likelihood of occurrence’ and ‘severity of impact’. The use of the developed approach is demonstrated through its application to total suspended solids, biochemical oxygen demand, lead and cadmium. The proposed benchmarking scheme represents a transparent and auditable mechanism to support the synthesis of data from a variety of sources and is sufficiently flexible to incorporate the use of chemical, physical and/or ecological data sets. Practitioners involved in developing and implementing pollutant mitigation programmes are assisted in two key ways. Firstly through enabling the risks to receiving waters from diffuse pollution on a source-by-source and/or pollutant-by-pollutant basis at a catchment scale to be comparatively assessed and prioritised. Secondly, the methodology informs the selection of appropriate diffuse pollution control strategies

Nature Reserves and Authoritarian Rule in Egypt: Embedded Autonomy Revisited

This article explores how Egypt\u27s system of authoritarian rule initially fostered and subsequently undermined nature conservation efforts. During the 1990s, international donors and local scientists established a well-managed network of nature preserves in the South Sinai region of Egypt. The concentration of state authority in a few executive institutions, such as the military and centrally appointed provincial governors, facilitated the creation of an effective management regime. However, these achievements have come under threat. Executive institutions charged with tourism development have challenged the authority of the protected areas division, and the capacity of the protected areas network has been undermined through systematic underinvestment and diversion of park revenues. In addition, local Bedouin communities that benefited from effectively managed parks remain politically marginalized. Although reformers in the authoritarian regimes of the Middle East can build environmental capacities, some of the economic and political logics associated with authoritarian rule limit the sustainability of these endeavors
