Existing studies have focused on flood protection and water quality locally with limited or lack of case studies on role of improved access to renewable energy as motivation for effectiveness and active community participation in catchment management. Community satisfaction and willingness to contribute in catchment restoration can be understood and may serve as reference on ways projects/government plan community involvement for instance in catchment rehabilitation of river basins with potential for power generation.
Abstract: A cultural health index (CHI) for streams was developed in a program of collaborative research involving members of Ngai Tahu (an iwi [tribe] within the South Island of New Zealand) and ecologists at Otago University. The aim was to provide a tool for effective participation of Maori in resource management decisions. Five cultural values are of central importance to the nature of the CHI: mauri (spiritual life force), mahinga kai (traditional resource harvesting), kaitiakitanga (guardianship obligation), ki uta ki tai (mountains-to-the-sea holistic philosophy), and wai taonga waters that are treasured). The CHI has three components. Forty-six stream sites in two culturally important river catchments were first classified according to whether there is a traditional association with Maori. The second component assessed the historical and contemporary mahinga kai status of the site, including questions of legal and physical access. The third component was a Cultural Stream Health Measure (CSHM) that encapsulates indicators of catchment, riparian, and instream condition in a manner that is consistent with Maori values. The CSHM was found to be significantly correlated with “western” measures of stream health commonly used in New Zealand (Macroinvertebrate Community Index, Stream Health Monitoring and Assessment Kit), and performed at least as well in encapsulating the relationship between land development and stream health. We describe a multistep process by which other indigenous people can develop a cultural ecosystem health measure, and then use the tool to ensure a substantial role in decision making with the agency in charge.

Abstract: Publication date: 1 May 2018 Source:Journal of Environmental Management, Volume 213 Author(s): Rohan Benjankar, Daniele Tonina, James A. McKean, Mohammad M. Sohrabi, Quiwen Chen, Dmitri Vidergar Dam operation impacts on stream hydraulics and ecological processes are well documented, but their effect depends on geographical regions and varies spatially and temporally. Many studies have quantified their effects on aquatic ecosystem based mostly on flow hydraulics overlooking stream water temperature and climatic conditions. Here, we used an integrated modeling framework, an ecohydraulics virtual watershed, that links catchment hydrology, hydraulics, stream water temperature and aquatic habitat models to test the hypothesis that reservoir management may help to mitigate some impacts caused by climate change on downstream flows and temperature. To address this hypothesis we applied the model to analyze the impact of reservoir operation (regulated flows) on Bull Trout, a cold water obligate salmonid, habitat, against unregulated flows for dry, average, and wet climatic conditions in the South Fork Boise River (SFBR), Idaho, USA.
