Systems Programme are leading the development, testing, design and modelling of effective mitigation systems, and assisting with their implementation and ongoing performance assessment.</p> <p>Nutrients, sediment, and microbial contaminants are mobilised from urban and agricultural landscapes and enter streams, rivers, lakes and estuaries. These contaminants can degrade water quality, ecological health, and cultural values.</p> <h3>Science solutions </h3> <p>NIWA’s research on Mitigation Systems aims to provide effective tools to enable government agencies and landowners to manage contaminant losses. </p> <p>Our work includes research on the performance and economic costs of various mitigation systems including riparian buffers,
