Germany is under increasing water stress, despite rising precipitation and extreme weather. The core issue lies not in rainfall quantity, but in the inability of our anthropogenically modified landscape to retain water. The Handbook of Agricultural Measures for Enhancing Water Retention, Water Quality and Biodiversity addresses this challenge head-on. Developed with farmers and advisors in mind, it presents field-tested and scientifically evaluated nature-based solutions for agricultural water management. These measures do not compete with productivity—they ensure long-term agricultural viability in a changing climate.

This poster provides a detailed insight into the new project "Water Stewardship" on behalf of WWF, which focuses on promoting water retention, water quality and biodiversity in German agriculture. The aim of this project is to strengthen resilience to climate change and improve ecosystem services through sustainable practices. The poster also refers to the conceptual background of the study as well as the future goals of the project, including the extension of the measures to other regions and political scales.

The German agriculture sector faces significant climate-related challenges due to extreme weather events along with shifts in temperature patterns, impacting crop yields and biodiversity and exacerbating water scarcity and water quality deterioration. The Panda Fördergesellschaft (on behalf of WWF) is commissioning Ecologic Institute to create a handbook, "Water Stewardship in German Agriculture," aiming to offer practical solutions to enhance water retention, quality, and biodiversity. The handbook will include an overview of Germany's water situation, legal framework, specific measures with contextualised examples, and ways to promote collective action.
