South Africa will require the establishment of a formal inclusive policy on sustainable agricultural practices. This will not only assist the country in avoiding further exploitation of the natural environment, but will also position agricultural extension in promoting the five pillars of sustainable agriculture. A comprehensive review using conceptual reflection presented in this paper confirms that most of the sustainable aspects are covered in both the white paper in sustainable agriculture and policy on agriculture in sustainable development. The existing documents, legislation, and policies available should be integrated into a working document that promotes sustainable agricultural practices. Thus, this paper provides a philosophical comparison between South Africa’s policy on agriculture in sustainable development and its white paper on agriculture. The review found that these two key South African agricultural policies are closely related in terms of the five pillars of sustainable agriculture. This paper further argues that the two policies reviewed could be used in the formulation of national policy on sustainable agriculture. In conclusion, this paper also suggests possible legislation addressing sustainable agriculture that should be integrated to develop a national policy on sustainable agriculture.
