a, Global map of HVFEs under the maximum delineation scenario, showing surface water bodies (rivers, lakes and reservoirs), headwater catchments, regularly flooded wetlands, geomorphic floodplains and fixed-width riparian corridors along low-order and high-order streams. Bubble sizes in the legend represent the global area of each HVFE component in million km2. b, Comparison of the maximum and minimum HVFE delineation scenarios (with and without floodplain). c, Top 50 countries ranked by the extent of fixed-width riparian corridors around high-order streams and lakes, representing the maximum possible buffer coverage within the HVFE framework. Percentages indicate each country’s contribution to the global total, with color coding representing different world regions.
