Veröffentlichung Indications of recent warm and dry summers' impact on private wells for drinking-water supply in Germany: a review of press articles(2022) Görnt, Annika; Rickert, Bettina; Vogelsang, L.; Ruhl, Aki SebastianClimatic changes lead to seasonal droughts with declining groundwater levels, and - especially in rural regions - private wells in the upper aquifer might fall dry. However, only limited information and no systematic administrative reporting of the extent are available for Germany yet. Therefore, a systematic analysis of newspaper articles as a promising source of information was conducted for the extraordinarily hot summers of 2018, 2019 and 2020. The results of the database searches were analysed with respect to frequency and local and regional hotspots, relations to climatic data, extent of the reported dry-fallings and emergency water supply. The analysis indicates hotspots particularly for the federal states of Saxony, where a subsidy programme for connecting to the public water supply was reissued in 2019, for Bavaria and North Rhine-Westphalia. Emergency supply was realised through various approaches. It was partly required until the winter months and did not always have drinking-water quality. As private wells are particularly vulnerable to the effects of climate change, their operators should be involved as a stakeholder group in future discussions about allocating water resources to increasingly competing uses in periods of scarcity. © 2022 The AuthorsVeröffentlichung Including aspects of climate change into water safety planning: Literature review of global experience and case studies from Ethiopian urban supplies(2019) van den Berg, Harold; Rickert, Bettina; Bekure, KasaIn recent years, the water safety plan approach has been extended towards climate-resilient water safety planning. This happened in response to increasing insight into impacts of climate on drinking-water and required adaptation to anticipated climate change. Literature was reviewed for published guidance and case examples, documenting how to consider climate in water safety planning to support future uptake. Climate-resilient water safety plans were piloted within a project in the water supplies of Addis Ababa and Adama, Ethiopia. Case examples have been published in four of six WHO regions with a focus on urban supplies. Integration of climate aspects focused mostly on the steps of establishing the team, system description, hazard analysis and risk assessment, improvement planning and development of management procedures. While the traditional framework focuses on drinking-water quality, considering climate change augments aspects of water quantity. Therefore, other factors affecting water quantity such as population development and demand of other sectors need to be considered as well. Local climate information and tools should be employed as a significant success factor for future uptake. Such information should be incorporated as it becomes available, and may - depending on the setting - be incrementally integrated into existing water safety plans or used to develop new ones. © 2019 The Authors.
