Rio Tinto, UNBC to research water security, fish ecology in Nechako Watershed

Rio Tinto (ASX: RIO) and the University of Northern British Columbia (UNBC) have expanded a partnership to advance vital research into the impacts of climate change on water security and freshwater fishes in the Canadian province’s Nechako Watershed.  The $1.75 million in research funding from Rio Tinto will support two Research Chairs at UNBC for the next five years, to generate regional knowledge critical to the long-term sustainability of the watershed while informing global water management and climate resilience efforts.  Environmental Science Professor Dr. Stephen Déry has been named Rio Tinto Research Chair in Climate Change and Water Security. The position is a renewal of an initial Industrial Research Chair (IRC) appointment jointly supported by Rio Tinto and the Natural Sciences and Engineering Research Council of Canada in 2019. The next phase of Déry’s research will include expanding the hydrometeorological monitoring and numerical modeling efforts developed through the IRC, as well as the development of forecasting systems to predict river water temperatures along the main stem Nechako River.  “Through the IRC program of research that began in 2019, our team has worked in collaboration with multiple partners including Rio Tinto to greatly expand our monitoring and understanding of climate change and meteorological phenomena such as atmospheric rivers,” Déry said.  “Over the next five years we will continue to closely monitor and investigate climate, atmospheric and hydrological conditions, processes and phenomena across the Nechako Watershed as the climate crisis continues to unfold,” Déry said.  Ecosystem Science and Management Associate Professor Dr. Eduardo Martins has been appointed Rio Tinto Research Chair in Climate Change and Freshwater Fish Ecology. His research will address knowledge gaps in how water temperature variability caused by both natural processes and river regulation influence fish behaviour and survival.  Findings from these research projects will help to support Rio Tinto’s operations in the watershed while providing guidance on the release of ecological flows“The Nechako Watershed is home to numerous fish species – sockeye salmon, Chinook salmon, rainbow trout, burbot and Nechako white sturgeon – that are important to the ecosystems as well as the First Nations and diverse cultures across the region,” Martins said. “Given their vulnerability to warmer water temperatures, the observed warming trends and recent extreme temperature events raise concerns about the long-term sustainability of many species.”  Working in collaboration with Déry, Martins will develop models exploring how changes in water temperature and future extreme events will impact freshwater fish populations in the watershed, informing critical fisheries management on keystone (salmon) and endangered (Nechako white sturgeon) aquatic species, as well as conservation policies and practices in the region.  Findings from these research projects will help to support Rio Tinto’s operations in the watershed while providing guidance on the release of ecological flows at the Skins Lake Spillway.  “Climate change is having a significant impact on the Nechako Watershed, which plays a vital role in our hydroelectric operations, First Nations cultural practices and the quality of life of local communities,” Andrew Czornohalan, director – Energy & Watershed Partnerships at Rio Tinto BC Works said in the statement.  “The research work conducted by Dr. Déry and his local team enhances our collective understanding of meteorological phenomena and their consequences on the environment. The expanded scope of our partnership with UNBC will provide additional scientific data to inform our collaborative approach to reservoir management and improving the river.”  The renewed partnership will sustain active outreach and engagement across the region as the UNBC Research Chairs and members of their teams work with local First Nations and a range of partners and community groups, Rio said.  In addition to the funding from Rio Tinto, UNBC will provide cash and in-kind contributions totalling approximately $1.3 million over the course of the five-year program, helping to support a team of 11 researchers, including master’s students, PhD candidates and post-doctoral fellows. Weiter zum vollständigen Artikel bei Mining.com Weiter zum vollständigen Artikel bei Mining.com
