Zusammenfassung |
Rivers in developed regions are under significant stress due to nutrient
enrichment generated mainly by human activities. Excess nitrogen and
phosphorus emissions are the product of complex dynamic systems influenced
by various factors such as demographic, socio-economic and technological
development. Using a Catalan river catchment, La Tordera (North-East of
Spain), as a case study of an integrated and interdisciplinary environmental
assessment of nutrient flows, we present and discuss the development of
narrative socio-economic scenarios through a participatory process for the
sustainable management of the anthropogenic sources of nutrients, nitrogen
and phosphorus. In this context, scenarios are an appropriate tool to assist
nutrient emissions modelling, and to assess impacts, possible pathways for
socio-economic development and associated uncertainties. Evaluated against
the 1993–2003 baseline period, scenarios target the 2030 horizon, i.e.
through the implementation process of the Water Framework Directive
(Directive 2000/60/EC). After a critical examination of the methodology used
in the participatory development of socio-economic scenarios, we present
four possible futures (or perspectives) for the Catalan river catchment
conceived by stakeholders invited to a workshop. Keys to the success of such
a participatory process were trust, which enhanced openness, and
disagreements, which fostered the group's creativity for scenario
development. The translation of narrative socio-economic scenarios into
meaningful nutrient emission scenarios is also discussed. By integrating
findings of natural sciences and socio-economic analysis, we aim to assist
decision makers and stakeholders in evaluating optimal management strategies
for the anthropogenic sources of nitrogen and phosphorus. |
