The Agriculture Portal
Agriculture encompasses crop and livestock production, aquaculture, fisheries and forestry for food and non-food products. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the twentieth century, industrial agriculture based on large-scale monocultures came to dominate agricultural output.
Today, small farms produce about a third of the world's food, but large farms are prevalent. The largest one percent of farms in the world are greater than 50 hectares and operate more than 70 percent of the world's farmland. Nearly 40 percent of agricultural land is found on farms larger than 1,000 hectares. However, five of every six farms in the world consist of less than two hectares and take up only around 12 percent of all agricultural land.
The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, eggs, and fungi. Global agricultural production amounts to approximately 11 billion tonnes of food, 32 million tonnes of natural fibres and 4 billion m3 of wood. However, around 14 percent of the world's food is lost from production before reaching the retail level.
Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, and technological developments have sharply increased crop yields, but also contributed to ecological and environmental damage. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and environmental damage. Environmental issues include contributions to climate change, depletion of aquifers, deforestation, antibiotic resistance, and other agricultural pollution. Agriculture is both a cause of and sensitive to environmental degradation, such as biodiversity loss, desertification, soil degradation, and climate change, all of which can cause decreases in crop yield. Genetically modified organisms are widely used, although some countries ban them. (Full article...)

However, despite immense land resources, extensive machinery and chemical industries, and a large rural work force, Soviet agriculture was relatively unproductive, hampered in many areas by the climate (only 10 percent of the Soviet Union's land was arable), and poor worker productivity. Conditions were best in the temperate black earth belt stretching from Ukraine through southern Russia into the west, spanning the extreme southern portions of Siberia.
Stalin's campaign of forced collectivization was a major factor explaining the sector's poor performance. Collectivization relied on a system of internal passports to keep farmers tied to the land. This has been referred to as a form of "neo-serfdom", in which the Communist bureaucracy replaced the former landowners. The first response of most farmers to this loss of freedom was to slaughter and consume their farm animals. In the new state and collective farms, outside directives failed to take local growing conditions into account. Also, interference in the day-to-day affairs of peasant life often bred resentment and worker alienation across the countryside. The human toll was very large with millions, perhaps as many as 3 million, dying from famine in the wake of collectivisation. In the collective and state farms, low labor productivity was a consequence for the entire Soviet period.
The claims of inefficiency have, however, been criticized by Economist Joseph E. Medley of the University of Southern Maine, US. Statistics based on value rather than volume of production may give one view of reality, as public-sector food was heavily subsidized and sold at much lower prices than private-sector produce. In addition, the 2–3% of arable land allotted as private plots does not include the large area allocated to the peasants as pasturage for their private livestock; combined with land used to produce grain for fodder, the pasturage and the private plots total almost 20% of all Soviet farmland. Private farming may also be relatively inefficient, taking roughly 40% of all agricultural labor to produce only 26% of all output by value. Another problem is these criticisms tend to discuss only a small number of consumer products and do not take into account the fact that the kolkhozy and sovkhozy produced mainly grain, cotton, flax, forage, seed, and other non-consumer goods with a relatively low value per unit area. This economist admits to some inefficiency in Soviet agriculture, but claims that the failure reported by most Western experts would only be a myth. (Full article...)
