This chapter summarises recent findings on the impacts of agri-environmental (AE) measures (2008-13), with special attention to water loading and biological diversity. Indicator trends, and comparisons between sites subject and not subject to AE measures, were analysed. Measures with the most potential for reducing nutrient loading are those targeting fertiliser rates, nature management fields and plant cover. Biodiversity has benefited from farmer contracts regarding traditional biotope management, organic production, raising local breeds and so on, as well as non-productive investments like establishing constructed wetlands. Agricultural nutrient loading has decreased because of lower artificial fertiliser use, but nutrient leaching from manure around clustered animal production units is increasing and requires measures targeted to manure composition and disposal. The greatest threat to biodiversity derives from trends in landscape structure. Due to regional heterogeneity, the objectives, measures and support levels of the AE scheme should be customised more according to the region, production sector and individual farm, by means of farm-specific environmental management plans.
