Sustainability in South Africa in the light of worldviews: Practical theological perspectives. According to the index of Fund for Peace (FFP) regarding the sustainability of different countries, the situation in South Africa is unfavourable due to phenomena such as a growing demographic pressure on natural resources and unequal distribution of wealth. This condition can be attributed to a greater or lesser extent to the way in which South Africa is governed by the ruling party. The researchers investigate whether this unsustainable situation could possibly be connected to the worldview(s) of the ruling party. The concept worldview is briefly described and analysed in the context of the composition and development of the ruling political party. After that, some connections between worldview and sustainability are examined. The article concludes by exploring the way in which Christians who want to obey God’s Word in all aspects of their lives, should think about sustainability and about what they could do to improve the situation in South Africa. The central theoretical argument of this article is that a reformational worldview can provide a framework for people to evaluate and change, if necessary, their thinking, decisions and behaviour in order to promote sustainability in South Africa to the benefit of all her citizens.
