step-by-step analysis shows that high reductions in N (18%) <strong>and</strong> P (28%) are<br />
expected with changes in <strong>the</strong> groundwater pathway, whereas increases of 23% in N<br />
load <strong>and</strong> 23% in P load are expected to occur with changes in overl<strong>and</strong> flow. The<br />
decrease of emissions within <strong>the</strong> groundwater pathway is related to <strong>the</strong> reduction of<br />
ground water volumes, while <strong>the</strong> increase of emissions in overl<strong>and</strong> flow is due to <strong>the</strong><br />
change of water dynamics through <strong>the</strong> soil.<br />
VI.C.3 Final remarks<br />
In order to identify optimal strategies to reduce eutrophication in <strong>the</strong> NA Coastal Zone<br />
<strong>the</strong>re is a strong need to improve our underst<strong>and</strong>ing of <strong>the</strong> long-term effects of<br />
<strong>Climate</strong> <strong>Change</strong> in combination with projected changes in socio economic indicators.<br />
Our preliminary evaluation for <strong>the</strong> Po Catchment-NA coastal zone continuum<br />
suggests that climate changes may lead to significant variations in natural conditions<br />
producing effects on major driving forces related to eutrophication (see Table-VI.C.7).<br />
One of <strong>the</strong> major effects of <strong>Climate</strong> <strong>Change</strong> at <strong>the</strong> Po catchment scale is a significant<br />
variation in <strong>the</strong> water balance due to <strong>the</strong> reduction of precipitation. Thus, as a<br />
consequence, <strong>the</strong> natural system will likely be altered, with a reduction of water<br />
resources <strong>and</strong> <strong>the</strong> increase in water dem<strong>and</strong> for both human consumption <strong>and</strong><br />
productive activities, especially agriculture <strong>the</strong> major high water consumption<br />
economic activity in <strong>the</strong> Po Basin. Moreover, changes in natural conditions, as <strong>the</strong><br />
increase of extreme events, will likely modify <strong>the</strong> terrestrial system <strong>and</strong> exacerbate<br />
environmental problems caused by habitat loss leading to a reduction of biodiversity<br />
(animal species extinction). Meanwhile, in <strong>the</strong> North Adriatic Sea <strong>the</strong> effects of<br />
climate change combined with socio-economic development could seriously alter<br />
natural conditions not only in terms of eutrophication but also in terms of habitat<br />
destruction biodiversity loss, coastal erosion <strong>and</strong> loss of wetl<strong>and</strong> areas.<br />
