Managing land for food production in the twenty-first century: an outline

  • Published 2005


Agriculture is often seen as conservative in the sense that it changes only slowly. There are good reasons why this change is slow: agriculture is a complex activity that has to be adapted to particular environmental conditions, there must be no risk to food for the family, and the farmer has to perceive a material and usually financial benefit of any changes. It is nevertheless reasonable to assume that from the start of agriculture change has taken place in response to change in demand. The gradual change from hunting and gathering that supported limited, mobile populations to an increasing dependence on settled agriculture led to more and more people needing more productivity from the land. Archaeological and historical records tell us about early innovations, for example the evolution and spread of the deliberate production of crops in different parts of the world aided by the introduction of such techniques as the animal-drawn plough, irrigation and terracing. Up until the last few centuries changes to agricultural practices occurred slowly. The changes became more rapid with the expansion of cultivation into new lands, with an increase in the human population and, especially from the sixteenth century, with the spread of crops between continents and countries and the development of more farm implements. In the nineteenth and twentieth centuries the increase in demand for agricultural products was met by the use of more land, the introduction of higher-yielding crops and domesticated animals, and the use of fertilizers and pesticides. Of fundamental significance was the application of scientific methods. Farming no longer had to rely solely on experience and tradition. It could be made more secure by assessment of the natural resources, experimentation in the field and
