Dwindling profitability and water scarcity mean that South Africa has less than two thirds of the number of food producing farms it had in the early 1990s, says the latest agricultural trends report by the World Wide Fund for Nature.
The report indicates that failed land reform projects and the flight of commercial farmers from South Africa were not the only contributors to declining farming potential in the country.
The fund's chief executive, Morné du Plessis, said drought, declining rainfall or excessive demand for water was putting a strain on South African farming. In many instances the farms had been changed to other land uses, or consolidated into larger farming units to achieve economies of scale.
As a result, the area under maize, wheat and dairy has decreased significantly over the past 20 years. According to Agricultural Statistics 2008, production has remained relatively constant, indicating an increasing trend towards intensified production since less acreage was yielding a lot more than before.
This also meant that the remaining farms had generally increased their investment in irrigation, fuel, fertiliser, mechanisation and genetically modified seed inputs.
At the Agricultural Business Chamber Congress in June, head of Absa Agribusiness Ernst Janovsky pleaded with advisory services providers not to take advantage of vulnerable small-scale farmers by only promoting their products but to act in the interest of the country and also assist in soil preservation.
Last week, Du Plessis endorsed the World Wide Fund-SA and Nedbank's R8.3m investment partnership to facilitate the fund's sustainable agriculture programmes in this country. These programmes will focus on sustainable agricultural production practices, largely organic farming.
The report also warned that poorly managed intensive farming had a negative effect on the natural environment, on people's well-being and on a farmer's ability to adapt to change.
"A dependence on, and overuse of, synthetic fertilisers, pesticides and herbicides reduces long-term soil fertility, causes soil erosion, pollutes water supplies, poisons fragile ecosystems, exposes farmers and farm workers to toxins, and contributes to climate change through greenhouse gas emissions," the report said.
The report acknowledged that input costs required for intensive farming were increasing with higher oil prices and raw materials as well as exchange rate fluctuations, leaving farmers with little control over their business affairs.
It also cautioned against intensified mechanisation of agriculture, which would lead to fewer jobs on farms. The report warned against the unintended consequences of the move towards genetically modified crops, particularly those dependent on herbicides and fertilisers.
A case cited by the report occurred in 2007, when fertiliser imported from China and used on Eastern Cape pineapple farms was found to contain toxic levels of cadmium, arsenic and lead. This resulted in an export ban on South African pineapples by the EU.
The cumulative impact of the overuse of fertiliser was the factor that degraded farmlands and their vital catchment areas. "As a result, the long-term productivity declines and these areas become more vulnerable to climate change," the report said.
"Use of genetically modified crops and certain pesticides, herbicides and fertilisers may isolate South Africa from lucrative export markets. Relying on single-variety crops is also risky. If these crops fail to perform, it will have a significant impact on national production," the report concluded.
