In ancient Roman religion , Ops or Opis ( Latin : "Plenty") was a fertility deity and earth goddess of Sabine origin. Her equivalent in Greek mythology was Rhea .
77-479: In Ops's statues and coins, she is figured sitting down, as Chthonian deities normally are, and generally holds a scepter , or a corn spray and cornucopia . In Roman mythology the husband of Ops was Saturn . Ops is identified as Rhea in Greek mythology, whose husband was Cronus , the bountiful monarch of the golden age ; Cronus was Rhea's brother. In Latin writings of the time, the singular nominative ( Ops )
154-539: A holocaust , defined by the completely burned and destroyed nature of the offering. The sacrifice was performed on a low altar or in a pit in the ground, offered in the direction of the earth where chthonic deities would reside. The animal sacrifice was sometimes buried as well. The temples in which these sacrifices were performed were typically built outside city walls with caves and grottos being popular locations, believed to be openings for chthonic deities. Worshippers lowered their palms and faced them downwards toward
231-810: 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
308-470: 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
385-664: 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
462-444: 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
539-464: A libation. They were performed on high altars which resided outside of temples . The animal sacrifice was roasted with the smoke traveling upward toward the sky, in the direction of the Olympic gods. Once cooked, the worshippers would feast on the sacrifice with the idea that they were sharing this meal with the gods. The worshippers would eat the consumable portions of the animal and burn the rest for
616-447: 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
693-404: 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
770-492: 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
847-552: 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

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
1078-490: Is also related to opus , which means "work", particularly in the sense of "working the earth, ploughing, sowing". This activity was deemed sacred, and was often attended by religious rites intended to obtain the good will of chthonic deities such as Ops and Consus . Ops is also related to the Sanskrit word ápnas ("goods, property"). According to Roman tradition, the cult of Opis was instituted by Titus Tatius , one of

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
1232-444: 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
1309-464: Is historically accurate and/or useful. Some scholars, including van Straten, argue that the term is not archaeologically verifiable. Some of these scholars believe that the modern use of chthonic is much more binary and concrete than it was in Ancient Greece. Schlesier notes that discussions of chthonic practices often create a false sense of "normal" worship and "deviant" worship, again citing
1386-479: Is not attested; only the form Opis is used by classical authors. According to Festus (203:19), " Ops is said to be the wife of Saturn and the daughter of Caelus. By her they designated the earth , because the earth distributes all goods to the human genus " ( Opis dicta est coniux Saturni per quam uolerunt terram significare, quia omnes opes humano generi terra tribuit ). The Latin word ops means "riches, goods, abundance, gifts, munificence, plenty". The word
1463-438: 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
1540-569: Is the case, a few gods are most commonly considered chthonic due to their considerable role in the underworld and/or agriculture. These include Hades as he is the ruler of the underworld. Persephone is the Queen of the Underworld alongside Hades. She spends half the year in the underworld and the other half above the earth. The period when Persephone is in the underworld corresponds with winter while she personifies spring when she returns to above
1617-500: 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

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
1925-548: 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 ,

2464-793: 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
2541-524: 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

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

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
3003-597: The earth and underworld, in the direction of the chthonic gods. The goal of chthonic worship was to interact with gods beneath the earth so offerings were directed toward the ground to reach these deities. For this reason, incense was not used in Chthonic worship, as the smoke would rise upwards rather than downwards. Wine was not utilized in this form of worship, but instead honey was a common libation used. Sacrificial practices would not always follow these exact patterns, but these are differences which can allude to whether
3080-407: The earth was sown. These festivals also included activities that were called Consualia , in honor of Consus, her consort . When Saturn (as Cronus ) learned of a prophecy that his children by Opis would overthrow him, he ate his children one by one as they were born. Opis could not just stand by, so instead of giving Saturn their final child, Jupiter, she wrapped a rock in swaddling clothes, and fed

Chthonic and ouranic, or olympic, are not completely opposite descriptors. They do not cleanly differentiate types of gods and worship into distinct categories, but represent a cultic spectrum. These terms communicate associations with

In Greek, χθόνιος ( khthónios ) is a descriptive word for things relating to the underworld, which was in antiquity sometimes applied as an epithet to deities such Hermes , Demeter , and Zeus . The chthonic deities have been compared to the more commonly referred-to Olympic gods and their associated rites and cults. Olympic gods are understood to reference that which exists above
3311-504: The earth. It is for these reasons that she is mainly associated with the underworld as well as agriculture. Demeter is related to the underworld as she attempts to rescue Persephone from Hades in her grief. She is associated with agriculture and fertility. The Furies, or the Erinyes , reside in the underworld and are known for vengeance. Offerings were a significant aspect of Ancient Greek religion. They were used to communicate with

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,
3542-402: The god. While performing the sacrifice, worshippers would raise their palms open and upward, again gesturing toward the sky where the ouranic gods resided. Chthonic sacrifice was commonly defined by offering a black or dark-hided animal to the deity. Worshippers did not consume the sacrifice themselves, but instead burned the entirety of the animal for the god. This type of sacrifice is called
3619-407: The gods and commonly took the forms of sacrifice and libation . Offerings were central to the worship of both chthonic and ouranic gods, though the specifics of these rituals differed. These differences provide insight into the ways in which Greeks perceived chthonic and ouranic deities as well as the ways they related to them. Ouranic sacrifices took place during the daytime and included wine as
3696-422: 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
3773-441: 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
3850-476: The lower yield associated with organic farming and its impact on global food security . Recent mainstream technological developments include genetically modified food . By 2015, the agricultural output of China was the largest in the world, followed by the European Union, India and the United States. Economists measure the total factor productivity of agriculture, according to which agriculture in
3927-437: 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

The gender gap in land productivity between female- and male managed farms of
4081-440: 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
4158-477: The result of conflict, climate extremes and variability and economic swings. 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
4235-874: The role that individuals and organizations engaged in agriculture should play. 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
4389-439: 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
4466-488: 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,
4543-604: The stark binary which modern scholars may fall into. In response, Scullion articulates the benefits of the term chthonic as long as one also understands the fact that chthonic and Olympian are not mutually exclusive categories. The term serves to highlight differing aspects of religious practice. Scholars emphasize the importance of reserving the label of chthonic for situations that were explicitly labeled as such in Ancient Greece. Agriculture Agriculture encompasses crop and livestock production, aquaculture , and forestry for food and non-food products. Agriculture

She is remembered in De Mulieribus Claris , a collection of biographies of historical and mythological women by the Florentine author Giovanni Boccaccio , composed in 1361–1362. It is notable as the first collection devoted exclusively to biographies of women in Western literature.

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
4928-459: The underworld and/or agriculture. This makes some deities such as Hades , Persephone , and Erinyes more likely to be considered chthonic due to their proximity to the underworld. While this is the case, virtually any god could be considered chthonic to emphasize different aspects of the god. For example, Demeter and Hermes are categorized within the twelve Olympian gods but are often considered chthonic. Zeus has also been referenced with
5005-506: The underworld or agriculture. For example, Hermes Chthonios references Hermes' role as the underworld escort. In contrast, Charon does not necessitate a chthonic epithet as his relation to the underworld is his main attribution. Additional examples of deities with recorded epithets include Demeter Chthonia, Ge Chthonia, Persephone Chthonia, Zeus Chthonios, and Hecate Chthonia. As discussed, many deities can be considered chthonic based upon what attributes are being referenced. Though this

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

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
5929-584: 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,
