The world relative to its human population is quite large. It is 123 billion acres in size, of which 37 billion acres are land. This means that there are a notional four acres available for every man, woman and child in the predicted 2050 world population 0f nine billion, which would be an increase of two billion on the present population. But notional is not real, and what is noticeable when looking at how the 37 billion acres are used by nature and humanity is that the urban area, humanity’s footprint on the land patch, is extremely small, at 1.5 per cent. This conflicts with the common rhetoric of environmentalists, which too often comes fact-free.
Land use has historically tended to follow claims to ownership, defined as the right to the use of and disposal of land. The relationship between humans and land begins with a fundamental claim by some people or countries to “own” land. On that basis, the world divides into two simple categories: those countries that allow citizens to own the land to which they hold legal title and those that grant only tenancies to their citizens, permitting the state to claim a total prior right to the use of all land within its borders.
