In this paper the incremental values of water are calculated for irrigators
in the Fish-Sundays Scheme of
South Africa's Eastern Cape province. The socio-political pressure for redistribution
of agricultural resources
provided the imperative for this study. The model of the Fish-Sundays Scheme reflects
a survey of 50 000 ha
of fodder and citrus production. It explicitly models the water demand
on sixteen typical farms, for five
irrigation technologies, six crops and four livestock activities. The existing allocation
generates an average
value of R0.0423/m3/year, which increases to R0.0681/m3/year if farmer-to-farmer
trading is allowed given
existing infrastructure. Unrestricted trade raises the average value to R0.0719/m3/year.
The marginal cost of
additional water in the source basin is R0.05/m3/year for the first 315 million m3
and R1.27/m3/year to extend
capacity beyond that.
