Water management for irrigation requires suitable policy tools able to meet social
objectives
and private behaviour. The legal framework in the EU is today faced with the new
water framework
directive (60/2000), that sets up new criteria for water management, regulation and
pricing.
Among other things, the water framework directive introduces the principle of full
cost
recovery and the polluter pays principle for water users. For many areas of Italy,
this may be a
significant shift compared to present payment criteria, based on traditional rights,
political prices,
partial running cost coverage or others.
The aim of this paper is to analyse the problem of water regulation in agriculture
as applied to
irrigation issues. This is made by setting up and testing a simulation model based
on the integration
of a mathematical decision making model at farm level and a principal agent model
at the level of
irrigation boards.
The model allows to quantify water demand and the optimal regulation from the point
of view
of the policy maker. The results show major impacts of water availability and prices
on farm
income. The adoption of a mix of pricing instruments related at the same time to
crop rotation,
water consumption and pollution can significantly improve water policy efficacy.
