This is a preliminary assessment of the relative contributions of the major driving forces related to climate change on nutrient dynamics in the Po catchment-North Adriatic Sea continuum has been performed adopting the Driver-Pressure-State-Impact-Response (DPSIR) approach. In the DPSIR analysis, major driving forces included both human and pseudo-natural drivers (not properly natural because they are of anthropogenic origin) (see Table VI.C.1). The nutrient loads (i.e. environmental 184 Pressures) deriving from these Drivers are reported (see Table VI.C.2) (ABP, 1999) in terms of "Potential" and "Effective" loads for both nitrogen and phosphorous. Table-2 suggests that the contribution of diffuse sources is higher (69%) than point sources (31%) for nitrogen, whereas for phosphorous point sources contribute with 62% of the total and diffuse sources with the remaining 38%.

Abstract
This is a preliminary assessment of the relative contributions of the major driving forces related to climate change on nutrient dynamics in the Po catchment-North Adriatic Sea continuum has been performed adopting the Driver-Pressure-State-Impact-Response (DPSIR) approach. In the DPSIR analysis, major driving forces included both human and pseudo-natural drivers (not properly natural because they are of anthropogenic origin) (see Table VI.C.1). The nutrient loads (i.e. environmental 184 Pressures) deriving from these Drivers are reported (see Table VI.C.2) (ABP, 1999) in terms of "Potential" and "Effective" loads for both nitrogen and phosphorous. Table-2 suggests that the contribution of diffuse sources is higher (69%) than point sources (31%) for nitrogen, whereas for phosphorous point sources contribute with 62% of the total and diffuse sources with the remaining 38%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
