Agriculture is the practice of cultivating the soil, planting, raising, and harvesting both food and non-food crops, as well aslivestock production. Broader definitions also includeforestry andaquaculture. Agriculture was a key factor in the rise ofsedentary humancivilization, whereby farming ofdomesticated plants and animals created foodsurpluses that enabled people to live in the 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 20th century,industrial agriculture based on large-scalemonocultures came to dominate agricultural output.

As of 2021[update],small farms, of which the vast majority are one hectare (about 2.5 acres) or smaller, produce about one-third of the world's food. Moreover, five of every six farms in the world consist of fewer than 2 hectares (4.9 acres) and take up only around 12% of all agricultural land. In terms of total land use, large farms are dominant. While only 1% of all farms globally are greater than 50 hectares (120 acres), they encompass more than 70% of the world's farmland. Further, nearly 40% of all global agricultural land is found on farms larger than 1,000 hectares (2,500 acres).

Farms and farming greatly influencerural economics and greatly shaperural society, affecting both the directagricultural workforce and broaderbusinesses that support the farms and farming populations.

The major agricultural products can be broadly grouped intofoods,fibers,fuels, andraw materials (such asrubber andtimber). Food classes includecereals (grains),vegetables,fruits,cooking oils,meat,milk,eggs, andfungi. Global agricultural production amounts to approximately 11 billion tonnes of food, 32 million tonnes of natural fibers and 4 billion m3 of wood. However, around 14% of the world's food is lost from production before reaching the retail level.

Modernagronomy,plant breeding,agrochemicals such aspesticides andfertilizers, and technological developments have sharply increasedcrop yields, but also contributed toecological and environmental damage.Selective breeding and modern practices inanimal husbandry have similarly increased the output of meat, but have raised concerns aboutanimal welfare and environmental damage. Environmental issues includecontributions to climate change, depletion ofaquifers,deforestation,antibiotic resistance, andother agricultural pollution. Agriculture is both a cause of and sensitive toenvironmental degradation, such asbiodiversity loss,desertification,soil degradation, andclimate change, all of which can cause decreases in crop yield.Genetically modified organisms are widely used, althoughsome countries ban them.

Diversity in dry common beans
Diversity in dry common beans
"Bean" is a common name for large plantseeds of severalgenera of thefamily "fabaceae" (alternately "leguminosae") used for human food oranimal feed.

The whole young pods of bean plants, if picked before the pods ripen and dry, are very tender and may be eaten cooked or raw. Thus the term "green beans" means "green" in the sense of unripe (many are in fact not green in color). In some cases, the beans inside the pods of "green beans" are too small to comprise a significant part of the cooked fruit.Beans have significant amounts of fiber andsoluble fiber, with one cup of cooked beans providing between nine and 13 grams of fiber. Soluble fiber can help lower bloodcholesterol. Beans are also high inprotein,complex carbohydrates,folate, andiron.

Beans are one of the longest-cultivated plants.Broad beans, with seeds the size of the small fingernail, were gathered in their wild state inAfghanistan and the Himalayan foothills. In a form improved from naturally occurring types, they were grown in Thailand already since the early seventh millennium (BC), predating ceramics. They were deposited with the dead inancient Egypt. Not until the second millennium BC did cultivated, large-seeded broad beans appear in the Aegean, Iberia and transalpine Europe. In the "Iliad" (late-8th century) is a passing mention of beans andchickpeas cast on the threshing floor. The oldest-known domesticated beans in the Americas were found inGuitarrero Cave, an archaeological site inPeru, and dated to around the second millennium BCE.(Full article...)
