Phosphorus Yield Category

In cases were the watersheds are exploited for intensive agricultural purposes, as consequence the fertilizer concentration increase. Thus, the fertilizer filters into the water and rise the accumulation of common nutrients, phosphorus and nitrogen, affecting their proper cycle. Around 384 million urbanities receive their drinking water from watersheds with high nutrient pollution. This map shows the total quantity of phosphorous moving out of a watershed in a given time interval, being expressed as units of tonnes/km2/year, organized into four categories: “Low” if 20 kg/km2 and “No Information”.
