In agriculture, resistance through variability is compromised, since genetically uniform seeds are planted under uniform conditions. Monocultural agriculture thus causes low crop diversity, especially when the seeds are mass-produced or when plants (such as grafted fruit trees and banana plants) are cloned.
Agricultural monocultures refer to the practice of planting one crop species in a field. [15] Monoculture is widely used in intensive farming and in organic farming.In crop monocultures, each plant in a field has the same standardized planting, maintenance, and harvesting requirements resulting in greater yields and lower costs.
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least ...
World production of primary crops by commodity groups, 2022 World agricultural land by use, 2022 Cropland area in 2022. There was an increase in global production of primary crops by 56% between 2000 and 2022 to 9.6 billion tonnes, which represents a 0.7% compared to 2021. [2] This represents 3.5 billion tonnes more than in 2000. [2]
Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation.Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science.
[32]: 29 During the same period, the number of people involved in farming dropped as the process became more automated. In the 1930s, 24 percent of the American population worked in agriculture compared to 1.5 percent in 2002; in 1940, each farm worker supplied 11 consumers, whereas in 2002, each worker supplied 90 consumers.

The number of women working in agriculture has risen and the 2002 census of agriculture recorded a 40% increase in the number of female farm workers. [69] Inequality and respect are common issues for these workers, as many have reported that they are not being respected, listened to, or taken seriously due to traditional views of women as ...
Species diversity refers to the number and abundance of different species used for food and agriculture. The number of species considered to contribute to food alone ranges from 5,538 to 75,000 depending on definitions. [11] A conservative estimate is that about 6,000 species are commonly used for food.
