Resumen
Descripción
The Austrian agri-environment program (ÖPUL) from 2000-2006 introduced several measures to reduce nitrate concentration in groundwater. We apply spatial econometric methods on a country-wide panel dataset to assess the partial effects of ÖPUL and other determining factors on nitrate concentration in groundwater. Preliminary results reveal that organic farming and refraining from using inputs on arable land have a measurable negative effect on nitrate concentration.
