Water water everywhere,but not enough for salmon? Organizing integrated water and fisheries management in Puget Sound

Natural resource management has traditionally been organized within discrete land, water, and fishery resource sectors. However, emerging environmental problems often cross these boundaries, and managers have struggled to find effective planning approaches for multi-resource concerns. No case better exemplifies these challenges than efforts to ensure sufficient flows of water for salmon in the Pacific Northwest. In this study, we investigate the organizational experiences of collaborative water and salmon recovery planning groups in the Puget Sound region of Washington. Using conceptual frameworks from organizational sociology, we examine how different regulative, normative, and cultural-cognitive institutional forces shape the structure and behavior of both water and salmon recovery planning groups. Data obtained through content analysis of planning documents and interviews with natural resource planners illustrate that legal structures, shared intra-group norms, and the distinct organizational cultures of water and salmon recovery groups constrain these organizations' ability to address linked water-for-salmon concerns. These findings illustrate that assessing institutional and organizational arrangements may be equally as important as understanding hydrology and biology when attempting to forward an integrated approach to water and fisheries management.     

Effect of co-culturing of methanogens with sulphur-reducing bacteria on biomethanation

Biomethanation as a result of co-culturing methanogenic bacteria with sulphate-reducing bacteria was studied under anoxic conditions. Toxic sulphur compounds are known not to inhibit methanogenesis. Hence varying experimental conditions can lead to the optimum conditions for biomethanation. Under controlled experimental conditions, the interacting behaviour of both isolated methanogens and sulphate reducers show interesting features, viz. allelopathy.     

Organizational change and marine environmental protection: The dredge spoil siting record

Dredge spoil siting activities are reviewed over a decade to determine whether organizational changes within the Corps of Engineers produced changes in the environmental performance of the agency. Over the period neither the total amount of marine and estuarine dredging nor the incidence of siting spoil inside the baseline declined. Therefore, internal organizational changes do not appear to have affected the above measures of agency performance concerning protection of the marine environment. Furthermore, at least 3% of the spoil is estimated to be highly contaminated. In recent years this magnitude of contaminated spoils has been equivalent to ocean-dumped sewage sludge.
