b'INTRODUCTIONFood production and environmental stewardship continue to be essential considerations from local to global scales. Food production for a growing world population and how this interfaces with the needs of a clean water resource and healthy biodiversity, and in the face of a changing climate is a challenge across the science-policy-producer-industry-consumer spectrum.For agriculture, the key challenge is for sustainable intensification.The overall theme of Catchment Science 2019, hosted by the Teagasc Agricultural Catchments Programme in Wexford, Ireland, is Achieving quality water in diverse and productiveagricultural landscapes under a changing climate. This highlights some of the challengeswe are currently facing within the scope of water quality management in agricultural landscapes. We draw on experiences from international science and policy programmes, and advisory and stakeholder engagement initiatives.There are eight inter-related themes providing a framework for the oral and poster presentations of this international conference:I.Soil analysis and nutrient managementII.Drivers, controls and time lagsmeeting the expectationsIII.Options for management approaches in reducing contaminant loss riskIV.Long-term in-situ monitoring and modelling of water qualityV.Impact of multiple stressors on aquatic ecologyVI.Decision support toolsVII.Integrated management, stakeholder engagement and catchment economicsVIII.Knowledge transfer, water governance and policy implementationThe conference includes a choice of four field visits of different themes and an interactive workshop.Catchment Science 2019Agricultural Catchments ProgrammeTeagascFunded by the Department of Agriculture, Food and the Marinei'
