6768-439: The same size is 24 percent. On average, women earn 18.4 percent less than men in wage employment in agriculture; this means that women receive 82 cents for every dollar earned by men. Progress has been slow in closing gaps in women's access to irrigation and in ownership of livestock, too. Women in agriculture still have significantly less access than men to inputs, including improved seeds, fertilizers and mechanized equipment. On

6862-513: The sensor and a conductive surface, such as rotating shaft. The displacements measured are extremely small, typically only several thousandths of an inch. Bently's application of eddy-current sensor technology was the foundation of an entire industry. Bently could be extremely demanding. He had high standards and did not compromise. He wrote, "Early in my career I decided that I would be absolutely true to my principles. This stand has led me occasionally to lose business, and sometimes lose employees. In

6956-488: The solution to concerns about food prices and overall food security , given the favorable experience of Vietnam. Agriculture provides about one-quarter of all global employment, more than half in sub-Saharan Africa and almost 60 percent in low-income countries. As countries develop, other jobs have historically pulled workers away from agriculture, and labor-saving innovations increase agricultural productivity by reducing labor requirements per unit of output. Over time,

His company of 224 men was instead ordered to Kwajalein Atoll , Marshall Islands, where it arrived on May 24. The unit (known as ACORN : for Aviation, Construction, Ordnance, Repair) constructed a major aviation facility on Kwajalein Atoll. The facilities were later used as

7614-671: The wild aurochs in the areas of modern Turkey and Pakistan some 10,500 years ago. Pig production emerged in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca , llamas , alpacas , and guinea pigs . Sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum

7708-744: The world consist of fewer than 2 hectares (4.9 acres), and take up only around 12% of all agricultural land. Farms and farming greatly influence rural economics and greatly shape rural society , affecting both the direct agricultural workforce and broader businesses that support the farms and farming populations. 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 fibers and 4 billion m of wood. However, around 14% of

7802-781: The world's agricultural land is seriously degraded. In recent years there has been a backlash against the environmental effects of conventional agriculture, resulting in the organic , regenerative , and sustainable agriculture movements. One of the major forces behind this movement has been the European Union , which first certified organic food in 1991 and began reform of its Common Agricultural Policy (CAP) in 2005 to phase out commodity-linked farm subsidies, also known as decoupling . The growth of organic farming has renewed research in alternative technologies such as integrated pest management , selective breeding, and controlled-environment agriculture . There are concerns about

7896-664: 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

7990-485: The world, women make up a large share of the population employed in agriculture. This share is growing in all developing regions except East and Southeast Asia where women already make up about 50 percent of the agricultural workforce. Women make up 47 percent of the agricultural workforce in sub-Saharan Africa, a rate that has not changed significantly in the past few decades. However, the Food and Agriculture Organization of

8084-495: The world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. As of 2021 , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than 50 hectares (120 acres) and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than 1,000 hectares (2,500 acres). However, five of every six farms in

8178-621: The world. Production is listed in millions of metric tons, based on FAO estimates. Animal husbandry is the breeding and raising of animals for meat, milk, eggs , or wool , and for work and transport. Working animals , including horses, mules , oxen , water buffalo , camels, llamas, alpacas, donkeys, and dogs, have for centuries been used to help cultivate fields, harvest crops, wrangle other animals, and transport farm products to buyers. Livestock production systems can be defined based on feed source, as grassland-based, mixed, and landless. As of 2010 , 30% of Earth's ice- and water-free area

8366-640: Was domesticated by the Mayo Chinchipe of the upper Amazon around 3,000 BC. The turkey was probably domesticated in Mexico or the American Southwest. The Aztecs developed irrigation systems, formed terraced hillsides, fertilized their soil, and developed chinampas or artificial islands. The Mayas used extensive canal and raised field systems to farm swampland from 400 BC. In South America agriculture may have begun about 9000 BC with

8460-560: Was domesticated in the Sahel region of Africa by 7,000 years ago. Cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia. In Mesoamerica , wild teosinte was bred into maize (corn) from 10,000 to 6,000 years ago. The horse was domesticated in the Eurasian Steppes around 3500 BC. Scholars have offered multiple hypotheses to explain the historical origins of agriculture. Studies of
