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.
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]
It was not until after 9500 BC that the eight so-called founder crops of agriculture appear: first emmer and einkorn wheat, then hulled barley, peas, lentils, bitter vetch, chick peas and flax. These eight crops occur more or less simultaneously on Pre-Pottery Neolithic B ( PPNB ) sites in the Levant , although wheat was the first to be grown ...
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.
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.
The two great economic revolutions that marked human history up to 1900—the agricultural and industrial revolutions—greatly increased the Earth's human carrying capacity, allowing human population to grow from 5 to 10 million people in 10,000 BCE to 1.5 billion in 1900. [44]
Agronomy – science and technology of producing and using plants for food, fuel, feed, fiber, and reclamation.. Organic gardening – science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
