Austrian Study Finds Farms Can Retain More Water

Why this is here: The study area, covering 1,500 square kilometers of the March river’s drainage basin, allowed researchers to model the effects of water retention techniques on a regional scale.

Hydrologist Bano Methi-Schulz from BOKU, working with the WWF in Austria, studied water retention on farms in the Weinviertel region. The research covered a roughly 1,500 square kilometer area draining into the March river.

The study shows that farms can hold more water by reducing soil disturbance and using mulch to lower evaporation. Fields with this approach provided crops more water during growth and reduced irrigation needs to two times instead of three.

Researchers also observed that grasslands near streams and beaver dams act as natural reservoirs. Combining these methods—like no-till farming, cover crops, and restoring natural buffers—creates a “natural sponge” effect. The WWF notes these solutions are currently used too little, despite the increasing threat of drought in Austria.

The study acknowledges that while these measures help, the long-term effects of climate change require continued attention and broader implementation of protective strategies. The work to improve water management continues.
