Subsistence agriculture
From Wikipedia, the free encyclopedia
Subsistence agriculture is self-sufficient farming in which farmers grow only enough food to feed the family, pay taxes or feudal dues. The typical subsistence farm has a range of crops and animals needed by the family to eat during the year. Planting decisions are made with an eye towards what the family will need during the coming year, rather than market prices. Tony Waters (2007:2) writes that "Subsistence peasants are people who grow what they eat, build their own houses, and live without regularly making purchases in the marketplace."
Subsistence grain-growing agriculture (predominantly wheat and barley) first emerged during the Neolithic Revolution when humans began to settle in the Nile, Euphrates, and Indus River Valleys. It was the dominant mode of production in the world until recently when market-based capitalism became widespread. Subsistence horticulture may have developed earlier in South East Asia and Papua New Guinea.
Subsistence farming continues today in large parts of up-country Africa (Hyden 1981), and other countries of Asia and South America. Subsistence agriculture had by and large disappeared in Europe by the beginning of World War I, and in North America with the movement of share croppers and tenant farmers out of the American South and Midwest during the 1930s and 1940s (Waters 2007:127-129).
[edit] Effects on the environment
Subsistence farming typically uses few fertilizers and no machines. Instead the farmers may use draft animals which can be fed and raised on the farm. Subsistence farmers often rely on crop rotation, animal manure, and compost to restore the nutrients rather than purchasing expensive synthetic fertilizers.
In areas which are sparsely populated, subsistence agriculture can be sustainable for a long time. In more densely populated areas, subsistence agriculture may deplete the soil of nutrients, and damage the environment. However the traditional agriculture of East Asia, for example the small-holdings of China, has been described as sustainable, using extensive methods of cultivation and despite high population pressure.
One form of subsistence agriculture is shifting cultivation, or swidden (different names in different places), a practice common with rain fed agricultural systems. Farmers typically abandon a given plot when soil fertility wanes and move on to more fertile land, often utilizing slash and burn techniques. A considerable fallow period ensues on the abandoned land. It takes up the least amount of land among the 4 types of cultivation but it is only enough for the town.
Despite what many people are led to believe, this practise is widespread in every country around the world, is not an inferior practise, and is generally far more environmentally viable and sustainable than commercial farming.[citation needed]
