| Abstract: | In the last decades the Common
Agricultural Policy has evolved towards a less intensive
approach based in a multifunctional agriculture
respectful with the environment. At the same time,
following the enacting of the Water Framework
Directive in 2000, water policies and management
regimes are also evolving towards more integrated water
management with an active stakeholders’ involvement.
In this context, the aim of this paper is to analyze the
impact of water conservation policies and agricultural
policies (Cross-Compliance: Nitrates Directive) in the
Upper Guadiana River basin (Spain), where intensive
irrigated agriculture resulted in the overexploitation of
the Western La Mancha aquifer and the subsequent
degradation of the highly valuable wetlands, and in an
important nitrates’ pollution. Focus is made on farmers’
vulnerability to these policies and the synergies between
them.
The methodology combines qualitative and
quantitative aspects defined by the integration of an
economic and an agronomic model (CropSyst), and a
vulnerability analysis. The economic model
(mathematical programming model) simulates farmers’
behaviour facing different policy options. The results of
the economic model are used as an input for the analysis
of farms’ vulnerability based on farm income indicators,
through the elaboration of a vulnerable farms
classification tree using CART (Classification and
Regression Trees).
The results of the model show that farm income is
more sensitive to water use limitations than to nitrogen
restrictions. Farm size and Water Authority’s policy
enforcement capacity are key variables in determining
farmers’ vulnerability, being small and legal farms the
most vulnerable ones. |
