<p>Reducing eutrophication requires large financial investments that can be for example used to support catchment stakeholders in building agri-environment mitigation measures. These measures aim at reducing nutrient and sediment losses from agricultural land to recipient waters. In recent years, a large number of studies has looked into their effectiveness and generally show that some measures are successful and others fail to deliver expected improvements in water quality, which is increasingly difficult to communicate to stakeholders expecting immediate results. Particularly, transport mitigation measures that aim at intercepting stream or drainage flow, can have a varying effectiveness. Two measures of the same type and built in a seemingly similar way can have completely opposite impact on water quality, depending on the local catchment properties. In this paper we examine factors controlling effectiveness of mitigation measures looking at their hydrochemical positioning in the catchment in relation to pollution sources including nutrient legacy sources, their hydrochemical behaviour, design, management and stakeholders’ engagement, using examples for transport mitigation measures: constructed wetlands, sedimentation ponds, two-stage ditches and drainage filters. We discuss also typical trade-offs in attainment of different ecosystem services which catchment stakeholders should consider prior to selecting and building the measures, including pollution swapping mechanisms e.g. reducing P-controlled eutrophication but increasing N-controlled eutrophication or reducing eutrophication vs. increasing greenhouse gas emissions. We show also how increasing weather variability and nutrient saturation can lead to further deterioration in water quality despite implementation of measures, making mitigation efforts ineffective under changing climate and in catchments with nutrient legacy sources.</p><p> </p>

This chapter studies how the menu is changing, highlighting key ingredients along the way, such as hops for beer, olive oil for salads, beef as a main course, rice as a side, and vanilla for desserts. Grains for beer are faced with excessive heat; changes in water quality and quantity are affecting spirits; and wine grape production is shifting to cooler climes. Salads are not immune, with avocados and olives facing more stressful higher temperatures and water shortages. The main course follows, with emphasis on beef, poultry, and fish as well as side dishes, and the chapter looks at how they are facing increased risks from a changing climate. The meal is finished with desserts and coffee. Eight million tons of chocolate is enjoyed worldwide, along with milk products like ice cream and cheese. The problems? Hot cows give less milk; intensifying storms in Madagascar disrupt production of vanilla; and our beloved coffee is at more risk because of spreading pests.
