Map of Total Sediment Yield and Reduction Potential
An interactive map shows the total sediment yield and the potential for mitigation strategies to reduce sediment losses from land to water by 2035.
The map allows users to zoom in to any of New Zealand’s catchments or regions, and swipe between two views. Swiping to the left reveals the sediment yield. Swiping to the right reveals the potential for on-farm actions to reduce suspended sediment loss to water.
This allows New Zealanders to see which rivers, lakes and estuaries are under the most pressure from agriculture, and whether all farmers adopting all on-farm mitigation actions will ease this pressure by 2035.
