dc.description.abstract | The share of nitrogen (N) that is exported to the sea or accumulated on land (N retention, sensu lato) involves different environmental processes; coastal eutrophication and anoxia in the first case; the acidification of soils, the emission of ammonia and greenhouse gases, and the pollution of aquifers in the latter. Nevertheless, the factors involved in N retention are still poorly constrained, particularly in arid and semi-arid systems. The present study evaluates the N fluxes of 38 catchments on the Iberian Peninsula with contrasting climatic characteristics (temperate and Mediterranean), land uses, and water management practices. The contribution of physical and socio-ecological factors in the retention of N was partitioned, and the link between N retention and water regulation was explored. We hypothesize that the extreme flow regulation performed in the Mediterranean enhances the high N retention values associated with arid and semi-arid regions. Our results show that reservoirs and irrigation channels account for >50% of the variability in N retention values, and above a certain regulation threshold, N retention peaks to values >85- 90%. Future climate projections forecast a decrease in rainfall and an increase in agricultural intensification and irrigation practices in many world regions, and notably in arid and semi-arid areas. Increased water demands will likely lead to a higher flow regulation, and the situation may resemble that of Mediterranean Iberian Peninsula catchments. High N retention and the associated environmental risks must therefore be considered as an important consequence of water regulation practices, and must be adequately managed | - |
