Small farms may be better for food security and biodiversity
We often assume the only way to feed the world's rapidly growing human population is with large-scale industrial agriculture. Many would argue that genetically altering food crops is also necessary to produce large enough quantities on smaller areas to feed the world's people.
But recent scientific research is challenging those assumptions. Our global approaches to agriculture are critical. To begin, close to one billion people are malnourished and many more are finding it difficult to feed their families as food prices increase. But is large-scale industrial farming the answer?
Large industrial farms are energy intensive, using massive amounts of fossil fuels for machinery, processing, and transportation. Burning fossil fuels contributes to climate change, and the increasing price of oil is causing food prices to rise. Deforestation and ploughing also release tonnes of carbon dioxide into the atmosphere, contributing further to climate change. And industrial farms require more chemical inputs, such as pesticides and fertilizers.
Agriculture also affects the variety of plant and animal species in the world. According to a review of scientific literature by Michael Jahi Chappell and Liliana Lavalle, published in the journal Agriculture and Human Values,
agricultural development is a major factor in the rapid decline in global biodiversity.
In their study -
Food security and biodiversity: can we have both? - the authors note that agriculture, which takes up about 40 per cent of the world's land surface (excluding Antarctica), "represents perhaps the biggest challenge to biodiversity" because of the natural habitat that gets converted or destroyed and because of the environmental impacts of pesticide and fertilizer use and greenhouse gas generation from fossil fuel use.
