This article describes the project "Drought and Water Use Conflicts in Germany (WADKlim)", its approach and objectives, and the context in Germany.

The project provides a nationwide overview of current water availability and its future development under climate change conditions. It analyzes emerging conflicts of use and develops possible solution strategies. For example, a concept for regional water advisory councils to strengthen intersectoral coordination will be designed. In addition, the potential of water reuse for irrigation in urban areas will be investigated.

The project is being carried out on behalf of the Federal Environment Agency (UBA)

Due to climate change, water retention in landscapes is gaining increasing relevance alongside flood protection. Various measures can improve the landscape water balance or enhance the resilience of land ecosystems against extreme weather events caused by floods and droughts. The authors have compiled a catalog of 69 measures in the UBA project WADKlim. These measures mostly originate from good practices in water management, agriculture, and forestry in Germany and have been evaluated based on their local impacts and implementation-relevant conditions.

Diagram illustrating the key hydrological parameters of water retention, including evaporation, transpiration, precipitation, surface runoff, infiltration, soil water retention, groundwater recharge, and discharge.

The infographic illustrates the key hydrological parameters that influence the water balance in ecosystems. The water cycle is illustrated, starting with precipitation through various phases such as evaporation, transpiration, surface runoff, seepage water movements and the recharge of groundwater. These processes are fundamental to understanding water cycles and their significance for the environment and climate. The visualization makes it clear how precipitation is filtered through the different earth layers and ultimately contributes to the replenishment of groundwater.

Event:Conference

After three years of intensive work, the results of the project "Drought and Water Use Conflicts in Germany (WADKlim)" were presented and discussed at the conference. The conference was addressed to experts related to water management issues from federal agencies, state offices and ministries as well as from authorities at regional level. Representatives from research institutions, associations, as well as practitioners attended.

Impacts of Climate Change on Water Availability

Final conference of the WADKlim project (Drought and Water Use Conflicts in Germany)

13 September 2023
Berlin, Germany

Presentation:Speech

At the Expert Hearing in the European Parliament on "Sustainable management of water and resources in agriculture" on 25 April 2023, Dr. Ulf Stein, Senior Fellow of Ecologic Institute and Coordinator of the Water Studies, was invited as one of four experts. The aim of the event was to speak on the relationship between agriculture and water management in the context of the increasing scarcity of water resources due to climate change. The talk aimed to explore best practices and policy options that can help manage agriculture's impact on water resources, as well as address challenges to agriculture due to weather events such as droughts and floods.

Publication:Flyer

As part of the project "Drought and Water Use Conflicts in Germany (WADKlim)", Ecologic Institute developed a promotional flyer based on visual style and template of the German Environment Agency. The flyer contains relevant general information about the project – its theme, focus, aims, activities and contact information.

Project

The project provides an overview of the current water availability in Germany, as well as its future development under climate change conditions. It predicts emerging conflicts of use and develops possible solution strategies. For example, a concept for regional water advisory councils will be developed. These are intended to avoid water conflicts by enabling representatives of water-relevant sectors to exchange information. In addition, options for reusing water for irrigation in urban areas are being examined.
