Inspired by winning a poetry competition at the age of seven, Ali's passion for writing grew with her children, culminating in the self-publication in 1995 of her first children's book about Monty, the Cape grey mongoose, Monty gets lost.

Within this arid zone the transport of coars egrained aeolian bedload, including diamonds, is dri ven by the impact of saltating sandflow, which produces a uniquely characteristic diamond dispersa l pattern as well as a variety of coarse-grained bedload features, textures and fabrics. For the first time the Namibian Aeolian System (NAS : see Annex 1 for abbreviations) which runs along the entire continental margin from the Orange River in the south to southern Angola in the north can be studied within the context of the recently d iscovered Benguela Low-Level Coastal Jet (BLLCJ). The structures produced in response to the hydrauli c behaviour of the BLLCJ flow are shown to influence strongly the location of zones of high-en ergy eros...
