Abstract: | Considering the important role of irrigation in the socio-economic development of
the Alentejo region in Portugal, this paper aims to assess the economic impact of
water pricing in the context of the public irrigation scheme of Odivelas. The methodological
framework uses Positive Mathematical Programming (PMP) and, as
an alternative, Econometric Mathematical Programming (EMP) based on the estimation
of optimality conditions. The model parameters were estimated using the
entropy approach and information priors. The models were formulated on the aggregated
scale of the irrigated scheme, considering the main regional irrigated
crops as well as land, labour, capital and water resources. The main results lead to
the conclusions that EMP model performs better than PMP and that under a twopart
tariff approach the block pricing scheme is better than the volumetric pricing
scheme. |
