18beplay官网 availability and quality will increasingly be impacted byclimate change, puttingvulnerable研究人员警告说,有危险的社区,除非现在采取措施建立韧性。

根据牛津大学领导的REACH研究计划本月发布的《气候弹性报告》,改善当地气候信息的获取并衡量天气对供水的影响对于推进水安全至关重要。

它说,尽管气候对干旱和洪水的影响是众所周知的,但经常绕过对社区层面的生活和生计的影响。

“The impact of climate change on water systems will continue to increase, threatening people’s lives and their quality of life, threatening the economic productivity of countries.”

Lead report author, Katrina Charles, a professor and senior research fellow at the University of Oxford and co-director of REACH, tellsSciDev.Net,研究人员致力于理解“我们如何改善包括最脆弱的人在内的每个人的水安全”。

她说:“改善水安全将有助于减轻气候变化的影响,并补充说,没有它,人们将非常容易受到水的稀缺性,水质变化,洪水泛滥。

“[The research] has helped us to understand […] not just the impacts of major events like floods and droughts, but the much more complex impacts of the changes in weather on people’s lives.”

该报告引用了孟加拉国的一个例子,孟加拉国更美好的天气将导致水质恶化,随着饮用水中的大雨增加,人们对人们的健康产生了影响。在干燥时期,河流中工业废水的稀释量较小,也使人们面临危险的重金属浓度。

Charles says that climate change is already altering the water cycle, changing the availability, reliability and quality of water available for drinking, agriculture, industry and the environment.

“The impact of climate change on water systems will continue to increase, threatening people’s lives and their quality of life, threatening the economic productivity of countries,” she added. “We need to act now to improve water security to help improve climate resilience.”

这项研究是因为联合国政府间关于气候变化的小组在本周具有里程碑意义的报告中警告说,热浪,洪水和干旱等极端天气事件变得越来越频繁,更加激烈。

世界卫生组织(世界卫生组织)和联合国儿童基金会最近还警告说,除非进程四元素的速度率,否则联合国可持续发展目标六,在2030年获得清洁水和卫生状态,将被错过。

Data-backed decisions

覆盖范围的报告强调,气候和水风险经历不平等,具有复杂的物理,政治,社会,行为和环境机制,影响了城市和农村社区的水安全。beplay足球体育的微博

Researchers say that although “water institutions are working towards climate resilience to manage risks from climate shocks and variability […] more needs to be done to integrate climate resilience into water policy and practice.”

作者建议进行更多的颗粒状或本地气候风险分析,以确保数据与特定社区有关。他们建议改进指标来监视气候弹性以跟踪进度并为投资决策提供信息。

他们说,还需要新的机构模型来改善水安全并促进气候夸大的决定。

Derek Vollmer, senior director of freshwater science, at Conservation International, says the report is important because of its emphasis on the local nature of water security issues.

他说:“报告的[三个]主要建议是一个很好的开始。”“这些都意味着长期的思维和投资,但旨在建立持久的地方能力。

“Climate change is introducing more uncertainty into our water systems. Local and regional decision makers will need to be equipped with both the information and the tools to explore adaptation measures, and to have a supportive policy environment that gives them the flexibility to manage their resources for resilience.”

The link between climate change and water security is becoming increasingly clear, according to Vollmer. But he added: “As the authors emphasise, these impacts will be different across locations, seasons, and even sub-populations within a specific place.

“Investing resources into more accurate regional climate models is necessary to provide robust forecasts for precipitation and streamflow, which are building blocks in resilience planning.”
