89-724: Large mechanized versions of rakes are used in farming , called hay rakes , are built in many different forms (e.g. star-wheel rakes, rotary rakes, etc.). Nonmechanized farming may be done with various forms of a hand rake. Modern hand-rakes usually have steel , plastic , or bamboo teeth or tines , though historically they have been made with wood or iron . The handle is typically a ~1.5 metres (5 ft) haft made of wood, bamboo, steel or fiberglass . Plastic rakes are generally lighter weight and lower cost. Because they can be fabricated in widths of greater dimensions they are more suitable for leaves which have recently been deposited. Metal tined rakes are better suited for spring raking when

178-810: A lord of the manor with a Roman Catholic church and priest. Thanks to the exchange with the Al-Andalus where the Arab Agricultural Revolution was underway, European agriculture transformed, with improved techniques and the diffusion of crop plants, including the introduction of sugar, rice, cotton and fruit trees (such as the orange). After 1492, the Columbian exchange brought New World crops such as maize, potatoes, tomatoes, sweet potatoes , and manioc to Europe, and Old World crops such as wheat, barley, rice, and turnips , and livestock (including horses, cattle, sheep and goats) to

267-426: A painting , stained glass , or tapestry . Cartoons were typically used in the production of frescoes , to accurately link the component parts of the composition when painted on damp plaster over a series of days ( giornate ). In media such as stained tapestry or stained glass, the cartoon was handed over by the artist to the skilled craftsmen who produced the final work. Such cartoons often have pinpricks along

356-470: A combination of labor supply and labor demand trends have driven down the share of population employed in agriculture. During the 16th century in Europe, between 55 and 75% of the population was engaged in agriculture; by the 19th century, this had dropped to between 35 and 65%. In the same countries today, the figure is less than 10%. At the start of the 21st century, some one billion people, or over 1/3 of

445-420: A dense thatch layer can impede the penetration of air and sunlight to the base of grass blades, potentially leading to lawn diseases. The removal of a substantial thatch layer, particularly if it measures 1/4-inch thick or thicker, proves beneficial for enhancing the overall health and vitality of the lawn. A reliable thatch rake stands out as an indispensable tool for effectively performing this task. A heavy rake

534-450: A fertilizer for crops. Cartoon A cartoon is a type of visual art that is typically drawn, frequently animated , in an unrealistic or semi-realistic style. The specific meaning has evolved, but the modern usage usually refers to either: an image or series of images intended for satire , caricature , or humor ; or a motion picture that relies on a sequence of illustrations for its animation. Someone who creates cartoons in

623-664: A hazardous industry, and farmers worldwide remain at high risk of work-related injuries, lung disease, noise-induced hearing loss , skin diseases, as well as certain cancers related to chemical use and prolonged sun exposure. On industrialized farms , injuries frequently involve the use of agricultural machinery , and a common cause of fatal agricultural injuries in developed countries is tractor rollovers . Pesticides and other chemicals used in farming can be hazardous to worker health , and workers exposed to pesticides may experience illness or have children with birth defects. As an industry in which families commonly share in work and live on

712-421: A heavy-duty variant of the normal rake, are used for fire prevention. If a rake lies in the ground with the teeth facing upwards, as shown on the top picture, and someone accidentally steps on the teeth, the rake's handle can swing rapidly upwards, colliding with the victim's face. This is often seen in slapstick comedy and cartoons , such as Tom and Jerry and The Simpsons episode " Cape Feare ", wherein

801-444: A high use of inputs (water, fertilizer, pesticide and automation). It is practiced mainly in developed countries. From the twentieth century onwards, intensive agriculture increased crop productivity. It substituted synthetic fertilizers and pesticides for labor, but caused increased water pollution, and often involved farm subsidies. Soil degradation and diseases such as stem rust are major concerns globally; approximately 40% of

890-447: A positive note, the gender gap in access to mobile internet in low- and middle-income countries fell from 25 percent to 16 percent between 2017 and 2021, and the gender gap in access to bank accounts narrowed from 9 to 6 percentage points. Women are as likely as men to adopt new technologies when the necessary enabling factors are put in place and they have equal access to complementary resources. Agriculture, specifically farming, remains

979-460: A rake, his " Nine-toothed rake " (Jiǔchǐdīngpá), as his signatory weapon. In Japanese folklore, the Kumade (熊手, lit. 'bear hand') is a rake; a smaller, handheld, decorated version is sold as an engimono , often during Tori-no-Ichi (lit. "Rooster markets) which take place throughout Japan each November, and is believed to be able to, literally, rake-in good-fortune &/or rake-out bad-fortune for

1068-510: A series of rakes become what Sideshow Bob describes as his "arch-nemesis". There is a Russian saying "to step on the same rake" ( Russian : наступить на те же грабли ), which means "to repeat the same silly mistake", also the word "rake" ( Russian : грабли ) in Russian slang means "troubles". In the 16th century Chinese novel Journey to the West , the major character Zhu Bajie wields

1157-794: A short series of cartoon illustrations in sequence. In the United States, they are not commonly called "cartoons" themselves, but rather "comics" or " funnies ". Nonetheless, the creators of comic strips—as well as comic books and graphic novels —are usually referred to as " cartoonists ". Although humor is the most prevalent subject matter, adventure and drama are also represented in this medium. Some noteworthy cartoonists of humorous comic strips are Scott Adams , Charles Schulz , E. C. Segar , Mort Walker and Bill Watterson . Political cartoons are like illustrated editorials that serve visual commentaries on political events. They offer subtle criticism which are cleverly quoted with humour and satire to

1246-404: A significant decrease in genetic diversity and resources among livestock breeds, leading to a corresponding decrease in disease resistance and local adaptations previously found among traditional breeds. Grassland based livestock production relies upon plant material such as shrubland , rangeland , and pastures for feeding ruminant animals. Outside nutrient inputs may be used, however manure

1335-444: A similar product The Beano in 1938. On some occasions, new gag cartoons have been created for book publication. Because of the stylistic similarities between comic strips and early animated films, cartoon came to refer to animation , and the word cartoon is currently used in reference to both animated cartoons and gag cartoons. While animation designates any style of illustrated images seen in rapid succession to give

1424-1212: A single drawing with a typeset caption positioned beneath, or, less often, a speech balloon . Newspaper syndicates have also distributed single-panel gag cartoons by Mel Calman , Bill Holman , Gary Larson , George Lichty , Fred Neher and others. Many consider New Yorker cartoonist Peter Arno the father of the modern gag cartoon (as did Arno himself). The roster of magazine gag cartoonists includes Charles Addams , Charles Barsotti , and Chon Day . Bill Hoest , Jerry Marcus , and Virgil Partch began as magazine gag cartoonists and moved to syndicated comic strips. Richard Thompson illustrated numerous feature articles in The Washington Post before creating his Cul de Sac comic strip. The sports section of newspapers usually featured cartoons, sometimes including syndicated features such as Chester "Chet" Brown's All in Sport . Editorial cartoons are found almost exclusively in news publications and news websites. Although they also employ humor, they are more serious in tone, commonly using irony or satire . The art usually acts as

1513-492: A small area of forest is cleared by cutting and burning the trees. The cleared land is used for growing crops for a few years until the soil becomes too infertile, and the area is abandoned. Another patch of land is selected and the process is repeated. This type of farming is practiced mainly in areas with abundant rainfall where the forest regenerates quickly. This practice is used in Northeast India, Southeast Asia, and

1602-482: A visual metaphor to illustrate a point of view on current social or political topics. Editorial cartoons often include speech balloons and sometimes use multiple panels. Editorial cartoonists of note include Herblock , David Low , Jeff MacNelly , Mike Peters , and Gerald Scarfe . Comic strips , also known as cartoon strips in the United Kingdom, are found daily in newspapers worldwide, and are usually

1691-552: A year, or requiring irrigation. In all of these environments perennial crops are grown (coffee, chocolate) and systems are practiced such as agroforestry . In temperate environments, where ecosystems were predominantly grassland or prairie , highly productive annual farming is the dominant agricultural system. Important categories of food crops include cereals, legumes, forage, fruits and vegetables. Natural fibers include cotton, wool , hemp , silk and flax . Specific crops are cultivated in distinct growing regions throughout

1780-473: A yearly summit to discuss safety. Overall production varies by country as listed. The twenty largest countries by agricultural output (in nominal terms) at peak level as of 2018, according to the IMF and CIA World Factbook . Cropping systems vary among farms depending on the available resources and constraints; geography and climate of the farm; government policy; economic, social and political pressures; and

1869-463: Is a heavy-duty tool with a flat edge for spreading and smoothing wet concrete and a curved side for scooping. Made of durable materials, it is essential for leveling concrete surfaces in construction. A roof rake features a long handle and a flat, scoop-like head for removing debris or snow from rooftops, preventing gutter clogs and structural damage, especially in snowy regions. Berry-picking rakes are tools for collecting berries. Fire rakes ,

1958-584: Is a hybrid of a Chilean and a North American species, developed by breeding in Europe and North America. The indigenous people of the Southwest and the Pacific Northwest practiced forest gardening and fire-stick farming . The natives controlled fire on a regional scale to create a low-intensity fire ecology that sustained a low-density agriculture in loose rotation; a sort of "wild" permaculture . A system of companion planting called

2047-626: 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 . The word agriculture is a late Middle English adaptation of Latin agricultūra , from ager 'field' and cultūra ' cultivation ' or 'growing'. While agriculture usually refers to human activities, certain species of ant , termite and beetle have been cultivating crops for up to 60 million years. Agriculture

2136-442: Is constructed from steel or aluminum. The head sits at a 90-degree angle to the handle. A thatch rake's primary function is to eliminate thatch—an organic layer situated between the lawn and the soil surface. Diverging from the typical structure of rakes, a thatch rake is equipped with sharp blades on both sides of its head. One side effectively breaks up the thatch, while the other side facilitates its removal. When left unaddressed,

2225-444: Is defined with varying scopes, in its broadest sense using natural resources to "produce commodities which maintain life, including food, fiber, forest products, horticultural crops, and their related services". Thus defined, it includes arable farming , horticulture, animal husbandry and forestry , but horticulture and forestry are in practice often excluded. It may also be broadly decomposed into plant agriculture , which concerns

2314-432: Is for conditioning and dethatching soil as well as moving larger pieces of debris. Most weeds have weaker and shallower roots than grass and thus dethatching along with (afterward) necessary sunlight, fertilizer and seed, and if later necessary any remedial chemicals, makes for a good crop of grass. Larger tools (or lawnmower attachments) are more often used for large areas of de-thatching or soil preparation. A concrete rake

2403-438: Is returned directly to the grassland as a major nutrient source. This system is particularly important in areas where crop production is not feasible because of climate or soil, representing 30–40 million pastoralists. Mixed production systems use grassland, fodder crops and grain feed crops as feed for ruminant and monogastric (one stomach; mainly chickens and pigs) livestock. Manure is typically recycled in mixed systems as

2492-500: The Indus Valley civilization . In China, from the 5th century BC, there was a nationwide granary system and widespread silk farming . Water-powered grain mills were in use by the 1st century BC, followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron ploughshares and mouldboards . These spread westwards across Eurasia. Asian rice was domesticated 8,200–13,500 years ago – depending on

2581-583: The Paleolithic , after 10,000 BC. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus . In India , wheat, barley and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle, sheep and goats were domesticated in Mehrgarh culture by 8,000–6,000 BC. Cotton was cultivated by the 5th–4th millennium BC. Archeological evidence indicates an animal-drawn plough from 2,500 BC in

2670-514: The Tigris and Euphrates rivers and a canal system for irrigation. Ploughs appear in pictographs around 3,000 BC; seed-ploughs around 2,300 BC. Farmers grew wheat, barley, vegetables such as lentils and onions, and fruits including dates, grapes, and figs. Ancient Egyptian agriculture relied on the Nile River and its seasonal flooding. Farming started in the predynastic period at the end of

2759-630: The molecular clock estimate that is used – on the Pearl River in southern China with a single genetic origin from the wild rice Oryza rufipogon . In Greece and Rome , the major cereals were wheat, emmer, and barley, alongside vegetables including peas, beans, and olives. Sheep and goats were kept mainly for dairy products. In the Americas, crops domesticated in Mesoamerica (apart from teosinte) include squash, beans, and cacao . Cocoa

2848-548: The organic movement . Unsustainable farming practices in North America led to the Dust Bowl of the 1930s. Pastoralism involves managing domesticated animals. In nomadic pastoralism , herds of livestock are moved from place to place in search of pasture, fodder, and water. This type of farming is practiced in arid and semi-arid regions of Sahara , Central Asia and some parts of India. In shifting cultivation ,

2937-482: The weaver would replicate the design. As tapestries are worked from behind, a mirror could be placed behind the loom to allow the weaver to see their work; in such cases the cartoon was placed behind the weaver. In print media, a cartoon is a drawing or series of drawings, usually humorous in intent. This usage dates from 1843, when Punch magazine applied the term to satirical drawings in its pages, particularly sketches by John Leech . The first of these parodied

3026-540: The Amazon Basin. Subsistence farming is practiced to satisfy family or local needs alone, with little left over for transport elsewhere. It is intensively practiced in Monsoon Asia and South-East Asia. An estimated 2.5 billion subsistence farmers worked in 2018, cultivating about 60% of the earth's arable land . Intensive farming is cultivation to maximize productivity, with a low fallow ratio and

3115-560: The Americas. Irrigation , crop rotation , and fertilizers advanced from the 17th century with the British Agricultural Revolution , allowing global population to rise significantly. Since 1900, agriculture in developed nations, and to a lesser extent in the developing world, has seen large rises in productivity as mechanization replaces human labor, and assisted by synthetic fertilizers , pesticides, and selective breeding . The Haber-Bosch method allowed

3204-536: The British strip Ally Sloper (first appearing in 1867) and the American strip Yellow Kid (first appearing in 1895). In the United States in the 1930s, books with cartoons were magazine-format " American comic books " with original material, or occasionally reprints of newspaper comic strips. In Britain in the 1930s, adventure comic magazines became quite popular, especially those published by DC Thomson ;

3293-586: The Paleolithic Levant, 23,000 years ago, cereals cultivation of emmer , barley , and oats has been observed near the sea of Galilee. Rice was domesticated in China between 11,500 and 6,200 BC with the earliest known cultivation from 5,700 BC, followed by mung , soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. Cattle were domesticated from

3382-486: The Three Sisters was developed in North America. The three crops were winter squash , maize, and climbing beans. Indigenous Australians , long supposed to have been nomadic hunter-gatherers , practiced systematic burning, possibly to enhance natural productivity in fire-stick farming. Scholars have pointed out that hunter-gatherers need a productive environment to support gathering without cultivation. Because

3471-793: The United Nations (FAO) posits that the roles and responsibilities of women in agriculture may be changing – for example, from subsistence farming to wage employment, and from contributing household members to primary producers in the context of male-out-migration. In general, women account for a greater share of agricultural employment at lower levels of economic development, as inadequate education, limited access to basic infrastructure and markets, high unpaid work burden and poor rural employment opportunities outside agriculture severely limit women's opportunities for off-farm work. Women who work in agricultural production tend to do so under highly unfavorable conditions. They tend to be concentrated in

3560-461: The United States is roughly 1.7 times more productive than it was in 1948. Agriculture employed 873 million people in 2021, or 27% of the global workforce, compared with 1 027 million (or 40%) in 2000. The share of agriculture in global GDP was stable at around 4% since 2000–2023. Despite increases in agricultural production and productivity, between 702 and 828 million people were affected by hunger in 2021. Food insecurity and malnutrition can be

3649-544: The annual work-related death toll among agricultural employees is at least 170,000, twice the average rate of other jobs. In addition, incidences of death, injury and illness related to agricultural activities often go unreported. The organization has developed the Safety and Health in Agriculture Convention, 2001 , which covers the range of risks in the agriculture occupation, the prevention of these risks and

This constitutes approximately 70% of the global employment of children, and in many countries constitutes the largest percentage of women of any industry. The service sector overtook the agricultural sector as the largest global employer in 2007. In many developed countries, immigrants help fill labor shortages in high-value agriculture activities that are difficult to mechanize. Foreign farm workers from mostly Eastern Europe, North Africa and South Asia constituted around one-third of

These may have somewhat finer and shorter teeth and can perform a myriad of gardening and landscape tasks, and due to their more costly construction are likely to be a professional tool. Alternatively, a second set of differently shaped teeth may be added to the back of the bar. A landscaping rake resembles an oversized garden rake, with a longer head. A landscaping rake serves

3916-597: The central west coast and eastern central, early farmers cultivated yams, native millet, and bush onions, possibly in permanent settlements. In the Middle Ages , compared to the Roman period , agriculture in Western Europe became more focused on self-sufficiency . The agricultural population under feudalism was typically organized into manors consisting of several hundred or more acres of land presided over by

4005-467: 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-scale monocultures came to dominate agricultural output. As of 2021 , small farms produce about one-third of

In Britain, Sir John Tenniel was the toast of London. In France under the July Monarchy , Honoré Daumier took up the new genre of political and social caricature , most famously lampooning the rotund King Louis Philippe . Political cartoons can be humorous or satirical, sometimes with piercing effect. The target of

4183-468: The cultivation of useful plants, and animal agriculture , the production of agricultural animals. The development of agriculture enabled the human population to grow many times larger than could be sustained by hunting and gathering . Agriculture began independently in different parts of the globe, and included a diverse range of taxa , in at least 11 separate centers of origin . Wild grains were collected and eaten from at least 105,000 years ago. In

4272-428: The debris is often wet or rotted and can best be collected when the metal tines penetrate to the thatch layer. Leaf rakes are used to gather leaves, cut grass and debris, have long, flat teeth bent into an L-shape and fanned out from the point of attachment. This permits some flexibility to allow the teeth to conform to terrain, while also being light to minimize damage to vegetation. Compact, telescoping leaf rakes allow

4361-529: 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

4450-668: The domestication of squash (Cucurbita) and other plants. Coca was domesticated in the Andes, as were the peanut, tomato, tobacco, and pineapple . Cotton was domesticated in Peru by 3,600 BC. Animals including llamas , alpacas , and guinea pigs were domesticated there. In North America , the indigenous people of the East domesticated crops such as sunflower , tobacco, squash and Chenopodium . Wild foods including wild rice and maple sugar were harvested. The domesticated strawberry

4539-532: The events of "Black Friday", when he allegedly betrayed the locked-out Miners' Federation . To Thomas, the framing of his image by the far left threatened to grievously degrade his character in the popular imagination. Soviet-inspired communism was a new element in European politics, and cartoonists unrestrained by tradition tested the boundaries of libel law. Thomas won the lawsuit and restored his reputation. Cartoons such as xkcd have also found their place in

4628-485: The extent that the criticized does not get embittered. The pictorial satire of William Hogarth is regarded as a precursor to the development of political cartoons in 18th century England. George Townshend produced some of the first overtly political cartoons and caricatures in the 1750s. The medium began to develop in the latter part of the 18th century under the direction of its great exponents, James Gillray and Thomas Rowlandson , both from London. Gillray explored

4717-432: The farm itself, entire families can be at risk for injuries, illness, and death. Ages 0–6 may be an especially vulnerable population in agriculture; common causes of fatal injuries among young farm workers include drowning, machinery and motor accidents, including with all-terrain vehicles. The International Labor Organization considers agriculture "one of the most hazardous of all economic sectors". It estimates that

4806-508: The first sense is called a cartoonist , and in the second sense they are usually called an animator . The concept originated in the Middle Ages , and first described a preparatory drawing for a piece of art, such as a painting, fresco , tapestry , or stained glass window. In the 19th century, beginning in Punch magazine in 1843, cartoon came to refer – ironically at first – to humorous artworks in magazines and newspapers. Then it also

4895-430: The forests of New Guinea have few food plants, early humans may have used "selective burning" to increase the productivity of the wild karuka fruit trees to support the hunter-gatherer way of life. The Gunditjmara and other groups developed eel farming and fish trapping systems from some 5,000 years ago. There is evidence of 'intensification' across the whole continent over that period. In two regions of Australia,

4984-422: The greater use of pesticides and fertilizers. Multiple cropping , in which several crops are grown sequentially in one year, and intercropping , when several crops are grown at the same time, are other kinds of annual cropping systems known as polycultures . In subtropical and arid environments, the timing and extent of agriculture may be limited by rainfall, either not allowing multiple annual crops in

5073-596: The humor may complain, but can seldom fight back. Lawsuits have been very rare; the first successful lawsuit against a cartoonist in over a century in Britain came in 1921, when J. H. Thomas , the leader of the National Union of Railwaymen (NUR), initiated libel proceedings against the magazine of the British Communist Party . Thomas claimed defamation in the form of cartoons and words depicting

In the 1980s, cartoon was shortened to toon , referring to characters in animated productions. This term was popularized in 1988 by the combined live-action/animated film Who Framed Roger Rabbit , followed in 1990 by

5251-441: The input of nutrients (fertilizer or manure ) and some manual pest control . Annual cultivation is the next phase of intensity in which there is no fallow period. This requires even greater nutrient and pest control inputs. Further industrialization led to the use of monocultures , when one cultivar is planted on a large acreage. Because of the low biodiversity , nutrient use is uniform and pests tend to build up, necessitating

5340-465: The leading cartoonist in the period following Gillray, from 1815 until the 1840s. His career was renowned for his social caricatures of English life for popular publications. By the mid 19th century, major political newspapers in many other countries featured cartoons commenting on the politics of the day. Thomas Nast , in New York City, showed how realistic German drawing techniques could redefine American cartooning. His 160 cartoons relentlessly pursued

Tapestry cartoons, usually colored, could be placed behind the loom , where

5607-437: The philosophy and culture of the farmer. Shifting cultivation (or slash and burn ) is a system in which forests are burnt, releasing nutrients to support cultivation of annual and then perennial crops for a period of several years. Then the plot is left fallow to regrow forest, and the farmer moves to a new plot, returning after many more years (10–20). This fallow period is shortened if population density grows, requiring

Sir John Tenniel —illustrator of Alice's Adventures in Wonderland — joined Punch in 1850, and over 50 years contributed over two thousand cartoons. Cartoons can be divided into gag cartoons , which include editorial cartoons , and comic strips . Modern single-panel gag cartoons, found in magazines, generally consist of

5874-440: The production of fish for human consumption in confined operations, is one of the fastest growing sectors of food production, growing at an average of 9% a year between 1975 and 2007. During the second half of the 20th century, producers using selective breeding focused on creating livestock breeds and crossbreeds that increased production, while mostly disregarding the need to preserve genetic diversity . This trend has led to

5963-578: The publisher sent observers around the country to talk to boys and learn what they wanted to read about. The story line in magazines, comic books and cinema that most appealed to boys was the glamorous heroism of British soldiers fighting wars that were exciting and just. DC Thomson issued the first The Dandy Comic in December 1937. It had a revolutionary design that broke away from the usual children's comics that were published broadsheet in size and not very colourful. Thomson capitalized on its success with

It can also be caused by a country's structural characteristics such as income status and natural resource endowments as well as its political economy. Pesticide use in agriculture went up 62% between 2000 and 2021, with the Americas accounting for half the use in 2021. The International Fund for Agricultural Development posits that an increase in smallholder agriculture may be part of

In the United States, agriculture has been identified by the National Institute for Occupational Safety and Health as a priority industry sector in the National Occupational Research Agenda to identify and provide intervention strategies for occupational health and safety issues. In the European Union, the European Agency for Safety and Health at Work has issued guidelines on implementing health and safety directives in agriculture, livestock farming, horticulture, and forestry. The Agricultural Safety and Health Council of America (ASHCA) also holds

In the United States of America, more than half of all hired farmworkers (roughly 450,000 workers) were immigrants in 2019, although the number of new immigrants arriving in the country to work in agriculture has fallen by 75 percent in recent years and rising wages indicate this has led to a major labor shortage on U.S. farms. Around

6408-439: 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

6497-488: 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,

6586-400: The synthesis of ammonium nitrate fertilizer on an industrial scale, greatly increasing crop yields and sustaining a further increase in global population. Modern agriculture has raised or encountered ecological, political, and economic issues including water pollution , biofuels , genetically modified organisms , tariffs and farm subsidies , leading to alternative approaches such as

6675-399: The teeth to be withdrawn by sliding a movable fixture point up the shaft. Garden rakes typically have steel teeth and are intended for heavier use in soil and larger debris. They have long, stiff teeth which must be able to withstand abrasion and bending forces. Bow rakes are a subset of garden rakes which separate the handle and bar with a bow-shaped extension which allows the flat back of

6764-679: The transition from hunter-gatherer to agricultural societies indicate an initial period of intensification and increasing sedentism ; examples are the Natufian culture in the Levant , and the Early Chinese Neolithic in China. Then, wild stands that had previously been harvested started to be planted, and gradually came to be domesticated. In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on

6853-443: The use of the medium for lampooning and caricature , and has been referred to as the father of the political cartoon. By calling the king, prime ministers and generals to account for their behaviour, many of Gillray's satires were directed against George III , depicting him as a pretentious buffoon, while the bulk of his work was dedicated to ridiculing the ambitions of revolutionary France and Napoleon . George Cruikshank became

6942-404: The user. [REDACTED] Media related to Hand rakes at Wikimedia Commons Agriculture Agriculture encompasses crop and livestock production, aquaculture , and forestry for food and non-food products. 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

7031-671: 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

7120-476: The world of science , mathematics , and technology . For example, the cartoon Wonderlab looked at daily life in the chemistry lab. In the U.S., one well-known cartoonist for these fields is Sidney Harris . Many of Gary Larson 's cartoons have a scientific flavor. The first comic-strip cartoons were of a humorous tone. Notable early humor comics include the Swiss comic-strip book Mr. Vieux Bois (1837),

7209-781: 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

7298-664: 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

7387-523: 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 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

7476-485: 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

7565-621: 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

7654-640: 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

7743-560: 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

7832-399: Was used for political cartoons and comic strips . When the medium developed, in the early 20th century, it began to refer to animated films that resembled print cartoons. A cartoon (from Italian : cartone and Dutch : karton —words describing strong, heavy paper or pasteboard and cognates for carton ) is a full-size drawing made on sturdy paper as a design or modello for

7921-584: Was used for producing livestock, with the sector employing approximately 1.3 billion people. Between the 1960s and the 2000s, there was a significant increase in livestock production, both by numbers and by carcass weight, especially among beef, pigs and chickens, the latter of which had production increased by almost a factor of 10. Non-meat animals, such as milk cows and egg-producing chickens, also showed significant production increases. Global cattle, sheep and goat populations are expected to continue to increase sharply through 2050. Aquaculture or fish farming,
