Global perturbation of organic carbon cycling by river damming

The damming of rivers represents one of the most far-reaching human modifications of the flows of water and associated matter from land to sea. Dam reservoirs are hotspots of sediment accumulation, primary productivity ( P ) and carbon mineralization ( R ) along the river continuum. Here we show tha...

Zusammenfassung:The damming of rivers represents one of the most far-reaching human modifications of the flows of water and associated matter from land to sea. Dam reservoirs are hotspots of sediment accumulation, primary productivity ( P ) and carbon mineralization ( R ) along the river continuum. Here we show that for the period 1970–2030, global carbon mineralization in reservoirs exceeds carbon fixation ( P
