Community Leader: Riemvasmaak
Mr Aubrey Adams was born on Riemvasmaak and attended school until standard 5, when the forced removal of the community was particularly brutal by the National Party regime which disrupted his schooling. Approximately 1 500 people were divided into three groupings: those who were classified under apartheid laws as Xhosa were moved to Welcomewood in the Ciskei in 1973, those who were classified of Nama or Damara heritage were forcibly relocated 1300 kilometres away to Khorixas in northern Namibia in 1973 and 1974, and finally, those who were classified as coloured remained in the areas surrounding Riemvasmaak area. Aubrey like most families in Namibia had to endure hardships. Some were placed at Otjihawera without shelter or means of protection, although there were lions in the area. They suffered stock losses and were completely cut off from the rest of the world, having no telephones, transport, schools or clinics. People found it difficult to get employment in Khorixas without Namibian citizenship, although some did manage to build up their farms and find employment. By June 1995, 96 families had returned to Riemvasmaak and eighteen families came from the Eastern Cape and the rest from Namibia. There was very little infrastructure when the people arrived, and development plans had to be formulated. Conditions were very difficult for the first few months. There was no housing apart from a few structures and houses remaining from the days of the mission. The people lived in rows of tents which were hot in warm weather and cold in cool weather. The community shared taps and toilets and two public telephones. There was no electricity.
Patrick Andre April
Community Leader: Vredesvallei
Mr Patrick Andre April (Andre) was born in Oshakati is a town of 37,000 inhabitants in the Oshana Region of Namibia. Andre completed his Standard 8 and became a builder and motor mechanic where he repairs motor vehicles in Vredesvallei and Riemvasmaak. He returned to Riemvasmaak in 1995 with a group of 96 families. As a community leader, Aubrey and Andre were instrumental with Dr George to form the Ho Oa Tago Mining Primary Co-operative Limited (Ho Oa Tago) a mining primary co-operative. Aubrey and Andre represent Ho Oa Tago as community leaders of Riemvasmaak and Vredesvallei on the Board of African Quartz. In 1993, Nelson Mandela, president of the African National Congress (ANC), stated that a new government would redress land inequality by using, among other mechanisms the redistribution of land controlled by the South African Defence Force. Riemvasmaak encapsulates the difficulties communities face as land use shifts from defence to development. The Riemvasmakers struggle was far from over when they regained land from the SANDF and has taken different forms as the people attempt to develop the land and rebuild a sense of community. Development has been a complex, protracted, and, at times, conflictual process. African Quartz offers a new opportunity through the leadership of Andre and Aubrey to heal the social divisions in the community along gender, ethnic, class and political lines; and a lack of community capacity to engage with development processes.
