South Africa has some of the highest levels of obesity in the world, together with exceptionally high rates of poverty. These two issues are linked in a vicious, attritional cycle.
At first glance it appears counter-intuitive to consider that poverty and obesity could be associated. The fact is that poverty is intimately correlated to several non-communicable diseases. Numerous international studies have shown how obesity and its morbid fellow travellers, hypertension and diabetes, stalk...

Land ownership is a prickly problem in South Africa, which has not yet been properly addressed, despite its prioritisation in 1994. The primary focus on land redistribution has understandably, but perhaps unwisely, centred on the issue of agricultural land holdings. Given increased rates of urbanisation, it can be argued that urban land tenure demands similar, if not higher levels of attention.
Land is at the foundation of conventional - and informal - economic wealth, in both developed...

While motorists feel the pain of the recent ascent of the oil price to near record levels, the underlying reality of rising oil prices has profound implications right across society.
Barring an unprecedented oil discovery, the world will never again see the return of cheap oil. Oil prices will certainly never return to the levels of the 1990s, or even the first half of the first decade of this century.

There is a concerted local drive to promote so-called “biofuels” by their supporters and agro-fuels by their opponents. The logic behind these different terms is worth...

The burden of an increasing global population forces us to reconsider how we deal with our dead. Our present system of burials and cremations is not only wasteful, it is unsustainable. Most of us now live in cities where space is at a premium. Using our limited land to house the dead is an anachronism. Incinerating dead bodies demands huge amounts of energy and releases serious pollutants.
Therefore, we not only need to tread more carefully on the earth when we are alive but we also need...

The South African tourism industry has grown tenfold over the past two decades. Tourists appreciate a benchmark to assist them in their choice of accommodation, for two reasons: First to indicate a consistent set of standards and second, to maintain these over time. However there are fundamental problems with the South African national tourism grading process, which require urgent attention.
The body responsible for assessing the quality of tourist establishments in South Africa is the...
