Water is scarce here. About 18 months ago a gale created dunes over the road - they were moved by bulldozer to the sides of the road, bushes grew on them but dried out during the summer. The ostriches - 2 females with chicks - that I wanted to photograph fled at high speed when I stopped the car. A little further on a windmill provided some water for stock. The farmers pump out so much water for their potato crops that the water table is dropping, seriously and the dunes could take over.
