91-623: The Building Centre is a building in central London for venue hire, used to promote innovation in the built environment . It is run by the Built Environment Trust, a charitable body which was formed in 2015 to replace an earlier charity, the Building Centre Trust, established in 1963. The centre was founded in 1931 starting as the building materials bureau of the Architectural Association . Its first managing director

182-461: A cardiovascular system in that they circulate people and materials throughout a city similar to how veins distribute energy and materials to the cells. Pedestrian circulation is vital for the walkability of a city and general access on a human scale. The quality of sidewalks and walkways have an impact on safety and accessibility for those using these spaces. Public transportation is essential in urban areas, particularly in cities and areas that have

273-787: 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

364-466: 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

455-542: A disadvantage. The historical segregation has contributed to environmental injustice, as these neighborhoods suffer from hotter summers since urban asphalt absorbs more heat than trees and grass. The effects of spatial segregation initiatives in the built environment, such as redlining in the 1930s and 1940s, are long lasting. The inability to feasibly move from forcibly economically depressed areas into more prosperous ones creates fiscal disadvantages that are passed down generationally. With proper public education access tied to

546-410: A diverse population and income range. Agricultural production accounts for roughly 52% of U.S. land use. Not only does population growth cause an expansion of cities, it also necessitates more agriculture to accommodate the demand for food for an expanding population. "Built environment" as a term was coined in the 1980s, becoming widespread in the 1990s and places the concept in direct contrast to

637-664: 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

728-444: 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

819-399: A large role in how people can feasibly navigate their environment. This can result in the isolation of certain communities from various resources and from each other. The placement of roads, highways, and sidewalks also determines what access people have to jobs and childcare close to home, especially in areas where most people do not own vehicles. Walkability directly influences community, so

910-447: 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

1001-419: A proper active lifestyle. Public health research has expanded the list of concerns associated with the built environment to include healthy food access , community gardens , mental health , physical health , walkability , and cycling mobility . Designing areas of cities with good public health is linked to creating opportunities for physical activity, community involvement, and equal opportunity within

1092-575: A shift is within the framework of the evolution of society. This shift caused the built aspect of these cities to grow and expand to meet the growing population needs. The pinnacle of city growth was during the Industrial Revolution due to the demand for jobs created by the rise in factories. Cities rapidly grew from the 1880s to the early 1900s within the United States. This demand led individuals to move from farms to cities which resulted in

1183-404: 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

1274-485: 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

1365-552: 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

1456-470: 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

1547-571: 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

1638-626: 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

1729-444: 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

1820-485: Is evidence to suggest that chronic disease can be reduced through healthy behaviors like a proper active lifestyle, good nutrition, and reduced exposure to toxins and pollutants. Yet, the built environment is not always designed to facilitate those healthy behaviors. Many urban environments, in particular suburbs, are automobile reliant, making it difficult or unreasonable to walk or bike to places. This condition not only adds to pollution, but can also make it hard to maintain

1911-560: Is made up of physical features. However, when studied, the built environment often highlights the connection between physical space and social consequences. It impacts the environment and how society physically maneuvers and functions, as well as less tangible aspects of society such as socioeconomic inequity and health. Various aspects of the built environment contribute to scholarship on housing and segregation , physical activity, food access, climate change , and environmental racism . There are multiple different components that make up

2002-610: Is only what is built, that the forests, oceans, wildlife, and other aspects of nature are their own entity. The term built environment encompasses a broad range of categories, all of which have potential impacts. When looking at these potential impacts, the environment, as well as people, are heavily affected. The built environment can heavily impact the public's health. Historically, unsanitary conditions and overcrowding within cities and urban environments have led to infectious diseases and other health threats. Dating back to Georges-Eugene Haussmann 's comprehensive plans for urban Paris in

2093-438: 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

2184-712: The Construction Products Association , and the UK Green Building Council . The building has an array of venue hire facilities, including galleries, seminar and conference rooms, and photography exhibition areas. Admission to the galleries on the ground floor and lower ground floor is free. There is a cafe open to the public with vegetarian, vegan and gluten free options, and indoor and outdoor seating. 51°31′10″N 0°07′54″W  /  51.5195°N 0.1316°W  / 51.5195; -0.1316 Built environment The built environment

2275-494: 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

2366-572: 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

2457-504: 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

2548-613: 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

2639-536: 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 ,

2730-511: The 1850s, concern for lack of air-flow and sanitary living conditions has inspired many strong city planning efforts. During the 19th century in particular, the connection between the built environment and public health became more apparent as life expectancy decreased and diseases, as well as epidemics, increased. Today, the built environment can expose individuals to pollutants or toxins that cause chronic diseases like asthma , diabetes , and coronary vascular disease, along with many others. There

2821-528: 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

2912-547: 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

3003-568: 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

3094-479: 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

3185-786: 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

3276-461: 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

3367-530: 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

3458-437: The assembly line production. With this new burst of personal transportation, new infrastructure was built to accommodate. Freeways were first built in 1956 to attempt to eliminate unsafe roads, traffic jams, and insufficient routes. The creation of freeways and interstate transportation systems opened up the possibility and ease of transportation outside a person's city. This allowed ease of travel not previously found and changed

3549-553: The available work force, were employed in agriculture. 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

3640-408: The built environment is already prominent, it pushes the boundaries of said built environment into new areas. While there are other factors that influence the built environment, like advancements in architecture or agriculture, transportation allowed for the spread and expansion of the built environment. Agriculture, the cultivation of soil to grow crops and animals to provide food as well as products,

3731-429: The built environment is typically used to describe the interdisciplinary field that encompasses the design, construction, management, and use of human-made physical influence as an interrelated whole. The concept also includes the relationship of these elements of the built environment with human activities over time—rather than a particular element in isolation or at a single moment in time, these aspects act together via

3822-403: The built environment. Below are some prominent examples of what makes up the urban fabric: Buildings are used for a multitude of purposes: residential, commercial, community, institutional, and governmental. Building interiors are often designed to mediate external factors and provide space to conduct activities, whether that is to sleep, eat, work, etc. The structure of the building helps define

3913-411: The built environment. Urban forms that encourage physical activity and provide adequate public resources for involvement and upward mobility are proven to have far healthier populations than those that discourage such uses of the built environment. Features in the built environment present physical barriers which constitute the boundaries between neighborhoods . Roads and railways , for instance, play

4004-580: 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

4095-468: 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

4186-656: 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

4277-455: The economic prosperity of a neighborhood, many formerly redlined areas continue to lack educational opportunities for residents and, thus, job and higher-income opportunities are limited. The built environment has a multitude of impacts on the planet, some of the most prominent effects are greenhouse gas emissions and Urban Heat Island Effect. The built environment expands along with factors like population and consumption which directly impact

4368-460: The environment, as well as quality of life. Urban Heat Islands are caused by reduction of natural landscape in favor of urban materials like asphalt, concrete, brick, etc. This change from natural landscape to urban materials is the epitome of the built environment and its expansion. Agricultural production Agriculture encompasses crop and livestock production, aquaculture , and forestry for food and non-food products. Agriculture

4459-416: The fabric of the built environment. New streets were being built within cities to accommodate cars as they became increasingly popular, railway lines were being built to connect areas not previously connected, for both public transportation as well as goods transportation. With these changes, the scope of a city began to expand outside its borders. The widespread use of cars and public transportation allowed for

4550-432: 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

4641-419: The forests and wild-life parks that are held on a pedestal and are seemingly natural are in reality curated and allowed to exist for the enjoyment of the human experience. The planet has been irrevocably changed by human interaction. Wildlife has been hunted, harvested, brought to the brink of extinction, modified to fit human needs, the list goes on. This argument juxtaposes the argument that the built environment

4732-430: 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,

4823-422: 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

4914-471: The idea that the built environment not only refers to that which is built, arranged, or curated, but also to what is managed, controlled, or allowed to continue. What is referred to as "nature" today can be seen as only a commodity that is placed into an environment that is constructed to fulfill the human will and desire. This commodity allows humans to enjoy the view and experience of nature without it inconveniencing their day-to-day life. It can be argued that

5005-430: The implementation of suburbs; the working individual was able to commute long distances to work everyday. Suburbs blurred the line of city "borders", the day-to-day life that may have originally been relegated to a pedestrian radius now encompassed a wide range of distances due to the use of cars and public transportation. This increased accessibility allowed for the continued expansion of the built environment. Currently,

5096-546: The industrial revolution was the City Beautiful movement . The City Beautiful movement emerged in the 1890s as a result of the disorder and unhealthy living conditions within industrial cities. The movement promoted improved circulation, civic centers, better sanitation, and public spaces. With these improvements, the goal was to improve the quality of life for those living in them, as well as make them more profitable. The City Beautiful movement, while declined in popularity over

5187-441: 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

5278-469: 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

5369-557: The modernist architects Taperell and Haase as a Daimler motor showroom. It is built of reinforced concrete, faced with Portland stone . When converted to the Building Centre, a sgraffito mural by Augustus Lunn was installed in the open-air courtyard and patio, although this has since been hidden or lost. Organisations located at the building include: the Built Environment Trust, the Construction Industry Council ,

5460-455: The multiplier effect. The field today draws upon areas such as economics , law, public policy , sociology , anthropology , public health, management , geography , design, engineering, technology, and environmental sustainability to create a large umbrella that is the built environment. There are some in modern academia who look at the built environment as all-encompassing, that there is no natural environment left. This argument comes from

5551-422: The need to expand city infrastructure and created a boom in population size. This rapid growth in population in cities led to issues of noise, sanitation, health problems, traffic jams, pollution, compact living quarters, etc. In response to these issues, mass transit, trolleys, cable cars, and subways, were built and prioritized in an effort to improve the quality of the built environment. An example of this during

5642-652: The output of greenhouse gases. As cities and urban areas grow, the need for transportation and structures grows as well. In 2006, transportation accounted for 28% of total greenhouse gas emissions in the U.S. Building's design, location, orientation, and construction process heavily influence greenhouse gas emissions. Commercial, industrial, and residential buildings account for roughly 43% of U.S. CO 2 emissions in energy usage. In 2005, agricultural land use accounted for 10–12% of total human-caused greenhouse gas emissions worldwide. Urban heat islands are pockets of higher temperature areas, typically within cities, that effect

5733-501: The people who live and work there. George Galster and Patrick Sharkey refer to this variation in geographic context as "spatial opportunity structure", and claim that the built environment influences socioeconomic outcomes and general welfare. For instance, the history of redlining and housing segregation means that there is less green space in many Black and Hispanic neighborhoods. Access to parks and green space has been proven to be good for mental health which puts these communities at

5824-437: 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

5915-414: The poorest countries, where alternative livelihoods are not available, and they maintain the intensity of their work in conditions of climate-induced weather shocks and in situations of conflict. Women are less likely to participate as entrepreneurs and independent farmers and are engaged in the production of less lucrative crops. The gender gap in land productivity between female- and male managed farms of

6006-440: 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

6097-477: 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

6188-844: 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

6279-474: The salaried agricultural workforce in Spain, Italy, Greece and Portugal in 2013. 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

6370-439: 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

6461-488: 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,

6552-414: The space around it, giving form to how individuals move through the space around the building. Public infrastructure covers a variety of things like roads, highways, pedestrian circulation, public transportation, and parks. Roads and highways are an important feature of the built environment that enable vehicles to access a wide range of urban and non urban spaces. They are often compared to veins within

6643-406: The supposedly "unbuilt" environment. The term describes a wide range of fields that form an interdisciplinary concept that has been accepted as an idea since classical antiquity and potentially before. Through the study of anthropology , the progression of the built environment into what it is today has been able to be examined. When people are able to travel outside of urban centers and areas where

6734-400: 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

6825-655: 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

6916-403: The way a neighborhood is built affects the outcomes and opportunities of the community that lives there. Even less physically imposing features, such as architectural design , can distinguish the boundaries between communities and decrease movement across neighborhood lines. The segregation of communities is significant because the qualities of any given space directly impact the wellbeing of

7007-656: 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

7098-744: 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

7189-774: 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

7280-664: 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

7371-481: 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

7462-495: 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

7553-621: 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

7644-426: The years, provided a range of urban reforms. The movement highlighted city planning, civic education, public transportation, and municipal housekeeping. The invention of cars, as well as train usage, became more accessible to the general masses due to the advancements in the steel, chemicals, and fuel generated production. In the 1920s, cars became more accessible to the general public due to Henry Ford's advances in

7735-620: Was Frank Yerbury , architectural photographer and secretary of the Architectural Association School, and its first chairman was Maurice Webb . It opened its doors on 7 September 1932 at 158 New Bond Street The Building Centre operated from New Bond Street until its building was destroyed during The Blitz on 12 May 1941. As a result, it moved to Conduit Street and was based there until 1951, when it moved to its present home in Store Street . The building had been designed by

7826-444: 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 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

7917-621: 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

8008-548: 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

8099-735: Was fertile and good for agricultural use. In these early communities, a priority was to ensure basic needs were being met. The built environment, while not as extensive as it is today, was beginning to be cultivated with the implementation of buildings, paths, farm land, domestication of animals and plants, etc. Over the next several thousand years, these smaller cities and villages grew into larger ones where trade, culture, education, and economics were driving factors. As cities began to grow, they needed to accommodate more people, as well as shifted from focusing on meeting survival needs to prioritizing comfort and desires – there are still many individuals today who do not have their basic needs met and this idea of

8190-496: Was first developed about 12,000 years ago. This switch, also called the Neolithic Revolution , was the beginning of favoring permanent settlements and altering the land to grow crops and farm animals. This can be thought of as the start of the built environment, the first attempt to make permanent changes to the surrounding environment for human needs. The first appearance of cities was around 7500 BCE, dotted along where land

8281-584: 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,
