Agricultural Best Managing Practices (BMPs) concerning Sedimentation

To help determine where watershed conservation can help secure water for cities, we estimated the effectiveness of five common conservation strategies: land protection, reforestation, riparian restoration, agricultural best management practices, and forest fuel reduction. For each strategy, we evaluated how effectively it reduces sedimentation and nutrient pollution in more than 2,000 source watersheds that serve over 500 cities. This map shows the potential of cities to do so in four categories: 100km2 is “Low”. Note that cities that predominately (>0.5) use something other than surface water, or cities that get the significant majority of their water (>0.66) from sources that this strategy cannot help, are classified as “Insufficient scope”.
