LuWQ2017 is an international and interdisciplinary conference on the cutting edge of science, management and policy to minimise effects of agriculture and land use changes on the quality of groundwater and surface waters. The aims of the Conferences are to discuss the entire a€™policy cyclea€™ to enable enhancing the quality of the water environment, which includes problem recognition, formulation of technical options, policy formulation, interaction between policy makers and stakeholders (i.e. pressure groups), policy implementation, monitoring and research. The conference also aims to facilitate networking opportunities between scientists of different discipline backgrounds i.e. economic, social and natural sciences, as well as between scientists, water managers and policy makers.
