Fertilizers and pesticides contribute to the pollution of water resources. The areas along streams are affected by climate change as stream bank failures often occur following floods or during prolonged rainfalls. In addition to BMP (best management practices) on the fields, grassed cover buffer zones are one of the most common measures for improving water quality in Norway’s agricultural catchments. Increased focus on buffer zones is important in a future climate perspective, both for food production, natural diversity and water quality. The efficiency of vegetation cover is composed of a variety of factors; therefore, effectives of these measures are to a large degree site specific. Recently, increased attention is given to the buffer zones efficiency, depending on both conditions in the catchments and the design of the buffer zones itself. However, most research is focusing in investigating the effect of buffer zones looking mostly at the surface runoff. According to our knowledge there is no previous research investigating the efficiency of the buffer zones with flower mixture. We focus on these types of vegetation as they also stimulate increased biodiversity. Moreover, previous investigations show that more than 50% of simulated runoff infiltrates into buffer zones with grass and bushes, while within buffer zones with trees there all the water infiltrates into the soil. Herein we show the results of 3 years monitoring surface runoff from buffer zones with different types of plant cover (grass and flower mixture). The idea was to monitor real live surface runoff from the field with autumn tillage (as “worst case scenario”). The results show significant differences, especially in the runoff quality. The visual differences are confirmed by water quality analysis.

Society increasingly expects that food will be produced in a sustainable, climate-smart manner. Nature based solutions (NBS), including ponds and constructed wetlands are widely promoted by researchers as a class of measures promoting healthy agricultural landscapes. However, a range of trade-offs associated with NBS influence practitioner’s decisions about their implementation and use. Making the right decisions about NBS requires, amongst other things, access to data from environmental monitoring programmes. The value of monitoring programmes depends on how well the data they collect and curate can be used to support decision-making. Here, we present a conceptual framework for assessing the value of monitoring programmes based on the relevance of the data they collect to decision maker needs, their overall running costs and their levels of uncertainty in characterizing the state of the environment. We demonstrate how our proposed framework can be used to assess the value of a range of monitoring programmes for quantifying trade-offs between nutrient load reduction and climate impacts from artificial wetlands in agricultural landscapes.
