Trends in Nitrogen Deposition [BIP]
Trends in Nitrogen Deposition [BIP]
Indicator description
The Nitrogen Deposition Indicator (NDI) shows where energy and food production have resulted in increased ammonia and nitrogen oxide emissions to the atmosphere on a global and regional basis, with subsequent increase in nitrogen depositions. There are large regions of the world where average nitrogen deposition rates exceed 10 kg N/ha/yr, greater than an order of magnitude increase compared with natural rates. These rates are well in excess of levels that have detrimental impacts on receiving ecosystems.
