Abstract
The Stompdrift and Kamanassie Irrigation Scheme provides water for 13 513 ha
in the Klein Karoo region of the Western Cape Province of South Africa. Water
losses are high in the unlined earth canals, which cover more than 50% of the
total length. The two dams can on average supply 22 million cubic meters per
annum (Mm3/a) of the total allocation of 28 Mm3/a. The fully allocated
quantities of water are supplied erratically, with only a fraction of the allocations
supplied in some years, with the result that about 40% of the land is irrigated in
most years.
Agriculture is the backbone of the economy of the whole region and the
socio-economic circumstances of the population, especially the historically
disadvantaged individuals, who rely heavily on agriculture. It is thus essential
that the available water should be optimally utilised for the benefit of all.
Several studies in the past could not find an economical solution to the
problem and a new study was commissioned to investigate water usage and more
beneficial uses. The economic feasibility of developing sources of additional
water was reviewed in terms of the current economic conditions.
The improved efficiency of water use, the possible augmentation of water
resources, the improved management of the water scheme and the possible
effects it can have on poverty alleviation in the area, are discussed.
Keywords: water use efficiency, best management practices, irrigation, plant
water requirements, water conservation, agriculture.
