Global Water Sustainability and Ecohydrology

水质下降是一个日益严重的全球性问题。随着人口的增加，多种因素，从密集的农业实践和广泛使用商业肥料，到威胁我们饮用水供应的气候变化和野火，再到快速城市化和集中畜牧业活动产生的新污染物，都威胁着我们的水资源。已经制定了多项新政策来改善我们湖泊和溪流的水质;然而，水质仍然是一个持续的挑战。 拟议的加拿大全球水可持续性和生态水文学研究主席致力于通过三个雄心勃勃的目标，提高我们在区域和全球范围内可持续管理水资源的能力，每个目标都具有突破性的潜力。具体而言，该计划将结合联合收割机自上而下的分析（O 1）-使用大型地理空间数据集，以确定流域功能特性-和机械建模，结合当前的土地利用和积累的营养遗产的影响，从几十年的施肥，对水质趋势（O2）。开发的模型将用于设计水质解决方案（O3），如湿地恢复和营养管理，从而在满足不断增长的人口的粮食和能源需求的同时加强水资源保护。该主席将促进巴苏博士的愿景，即建立对人类影响景观中营养遗产和时间滞后的新的基本理解，并为创建适应性管理战略提供统一的框架，以加速国内和国际水质改善。这项世界级的研究将为与保护机构（例如，格兰德河保护局）和监管机构（例如，加拿大环境和气候变化部（ECCC）和美国环境保护署。随着环境压力的不断增加，生态系统和水资源面临风险，拟议的主席将从根本上帮助我们减轻这些压力，并为复杂的环境问题制定积极、建设性的解决方案。它最终将有助于加强加拿大在保护我们最宝贵资源方面的领导地位。

Declining water quality is a growing global issue. As the human population increases, a multitude of factors, from intensive agricultural practices and widespread application of commercial fertilizers, to climate change and wildfires threatening our drinking water supplies, to emerging contaminants from rapid urbanization and concentrated livestock operations, threaten our water resources. Multiple new policies have been developed to improve water quality in our lakes and streams; however, water quality remains a persistent challenge. The proposed Canada Research Chair in Global Water Sustainability and Ecohydrology strives to improve our ability to manage water resources sustainably at the regional and global scales through three ambitious objectives, each with ground-breaking potential. Specifically, this program will combine top-down analysis (O1) -- using large geospatial datasets to identify watershed functional traits -- and mechanistic modeling that incorporates the effect of both current land use and accumulated nutrient legacies, from decades of fertilizer applications, on water quality trends (O2). The models developed will be used to design water quality solutions (O3), such as wetland restoration and nutrient management, enabling enhanced water protection while meeting the food and energy needs of a growing population. The Chair will catalyze Dr. Basu's vision to establish new, fundamental understanding of nutrient legacies and time lags in human-impacted landscapes and provide a unified framework for creating adaptive management strategies that can accelerate water quality improvement, both nationally and internationally. This world-class research will provide important groundwork for creating policies on nutrient management and ecosystem protection in direct collaboration with conservation agencies (e.g., Grand River Conservation Authority), and regulatory bodies (e.g., Environment and Climate Change Canada - ECCC, and US Environmental Protection Agency). With growing environmental pressures that place ecosystems and water resources at risk, the proposed Chair will contribute at a fundamental level to our ability to alleviate these pressures and to devise positive, constructive solutions to complex environmental problems. It will ultimately help bolster a leadership position for Canada in the protection of our most valuable resources.
