In May 1901, Hellman, who had been Southern California's leading banker for almost three decades (and owned much property down there), wrote Huntington that "the time is at hand when we should commence building suburban railroads out of
840-470: 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
980-605: A complicated stock and bond transaction, Huntington conveyed his 50% of Pacific Electric to the Southern Pacific, while he acquired SP's 45% interest in the Los Angeles Railway. In addition, Huntington conveyed the Los Angeles and Redondo Railway to the Southern Pacific. Huntington retained control of the Los Angeles Railway , the narrow gauge street car system known locally as "Yellow Cars," until
1120-570: A controlling interest in this company was sold off by Huntington's estate in 1944. In what was called the "Great Merger" of September 1, 1911, the Southern Pacific created a new Pacific Electric Railway Company, with all electrical operations now under the Pacific Electric name. The constituent railroads were: Following these acquisitions, PE was the largest operator of interurban electric railway passenger service in

Pacific Electric The Pacific Electric Railway Company , nicknamed the Red Cars , was a privately owned mass transit system in Southern California consisting of electrically powered streetcars , interurban cars, and buses and was the largest electric railway system in the world in the 1920s. Organized around the city centers of Los Angeles and San Bernardino , it connected cities in Los Angeles County , Orange County , San Bernardino County and Riverside County . The system shared dual gauge track with
1400-565: A franchise plan with three-cent fare plan to the Los Angeles City Council, a plan which, if accepted, would have handicapped the other railways severely. Huntington countered with a ticket book which gave the rider 500 miles (800 km) of travel for $ 6.25 (equivalent to $ 212 in 2023), which undercut the Harriman strategy. The Council vetoed the franchise idea, unable to believe adequate service could be provided for such

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
1820-476: A line from Monrovia to Glendora . The system reached La Habra in 1908. By 1910 PE operated nearly 900 miles (1,400 km) of track. Routes had been built into or passed through areas just beginning to grow. 1905 was the Pacific Electric's most profitable year, when the road made $ 90,711 (equivalent to $ 3.08 million in 2023). Profits from the Huntington Land and Improvement Company made up for

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
2800-492: 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
2940-478: A small plant at the mouth of Kern Canyon. The following year, the Kern River and Los Angeles Electric Power Company obtained water rights on the river and planned construction of a power plant. This project, Borel Hydroelectric Project, was built to provide power for the growing Red Electric Streetcar (also known as Red Car ) transportation system in Los Angeles.

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

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
10500-477: The city." Hellman added that he had already tasked engineer Epes Randolph to survey and lay out the company's first line which would be to Long Beach. In that same year, Huntington and Hellman incorporated a new entity, the Pacific Electric Railway of California, formed to construct new electric rail lines to connect Los Angeles with surrounding cities. Hellman and his group of investors owned
10640-533: The completion of regulatory works on the Kern River. Their study also showed that an average benefit to irrigation and existing power facilities of $ 185,000 ($ 2.5 million today) could be gained as well. After the District filed its report, Congress authorized the Isabella Project in the 1944 Flood Control Act. Construction began in 1948, under contract with Rand Construction Company, and completed in 1953;
10780-471: The controlling majority of stock (double that of Huntington's) and the newspapers of the time referred to it as the Huntington-Hellman syndicate. Using surrogates, the syndicate began purchasing property and rights-of-way. The company's first main project, the line to Long Beach , opened July 4, 1902. Huntington experienced periods of opposition from organized labor with the construction of
10920-884: The country with the intention of shutting them down and converting them to bus operation in what became known as the Great American Streetcar Scandal . Several lines operating to the north and the west which used the Belmont Tunnel from the Subway Terminal Building downtown ceased operation – the Hollywood Boulevard and Beverly Hills lines were shut down in 1954 and service to the San Fernando Valley, Burbank and Glendale using newly acquired PCC streetcars lasted only to 1955. The Bellflower line to
11060-468: 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
11200-514: The dams. On April 28, 2006, a seepage problem was found in the Isabella Auxiliary Dam. Officials determined that it would be necessary to restrict the maximum reservoir elevation to 20 feet (6.1 m) below the spillway, or normal "full" pool. The dam's releases through the outlet were increased, allowing the water to flow at 4,500 cubic feet per second (130 m/s). In May 2006, due to more than average rainfall and snowpack in
11340-529: 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
11480-668: 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
11620-791: The dots on the map and was a leading player itself in developing all the real estate that lay in between the dots". Huntington's involvement with urban rail was intimately tied to his real estate development operations. Real estate development was so lucrative for Huntington and SP that they could use the Red Car as a loss leader . However, by 1920, when most of the company's holdings had been developed, their major income source began to deplete. Many rural passenger lines were unprofitable, with losses offset by revenue generated from passenger lines in populated corridors and from freight operations. The least-used Red Car lines were converted to cheaper bus routes as early as 1925. In 1936, Pacific Electric acquired
11760-480: The end of rail service in 1963. Large profits from land development were generated along the routes of the new lines. Huntington Beach was incorporated in 1909 and developed by the Huntington Beach Company, a real-estate development firm owned by Henry Huntington, which still owns both land in the city and most of the mineral rights. There are other local streetcar suburbs . Angelino Heights
11900-403: The enterprise. Revenue from passenger traffic rarely generated a profit, unlike freight. The real money for the investors was in supplying electric power to new communities and in developing and selling real estate. To get the railways and electricity to their towns, local groups offered the Huntington interest opportunities in local land. Soon Huntington and his partners had significant holdings in
12040-432: 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
12180-426: The federal government spent $ 22 million ($ 305 million today) for the project. Isabella Dam consists of two dams, a "main dam", and an "auxiliary dam". The main dam is of earthen build, 1,695 feet (517 m) long and 98 feet (30 m) tall, and owned and maintained by the U.S. Army Corps of Engineers . The main reservoir, Lake Isabella, can hold up 570,000 acre-feet (700,000,000 m) of water. Normal release from
12320-473: The few U.S. interurbans to do so. This provided important revenue. The PE was responsible for an innovation in grade crossing safety: the automatic electromechanical grade crossing signal, nicknamed the wigwag . This device was quickly adopted by other railroads. A few wigwags continue in operation as of 2006 . During this period, the Los Angeles Railway provided local streetcar service in central Los Angeles and to nearby communities. These trolleys were known as
12460-506: The final few miles from private right-of-way to reach the 6th and Main PE terminal and were bogged down within this jammed traffic. Schedules could not be met, plus former patrons were now driving. The San Bernardino line, Pomona branch, Temple City branch via Alhambra's Main Street, San Bernardino's Mountain View local to 34th Street, Santa Monica Boulevard via Beverly Hills, and all remaining Pasadena local services were all cut in 1941. Permission
12600-430: 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,
12740-422: 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
12880-484: The high water levels. Some flooding was reported by property owners along the river. Emergency management officials warned that if Isabella Dam were to fail when the reservoir was full, a large part of Bakersfield would be inundated within 2 to 4 hours. After the news of the seepage, the dam came under further attention due to being situated on a fault line. The fault line was thought to be inactive, but in February 2007,
13020-441: 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
13160-442: The lake's normal storage capacity, to reduce the risk of the seepage and seismic concerns while a permanent solution is investigated. USACE has implemented increased surveillance and monitoring; stockpiling of emergency materials; warning sirens in the town of Lake Isabella; installation of additional instrumentation for monitoring; and continued public outreach with Kern County and the local public. In September 2017, The Corp awarded
13300-418: The land companies developing Naples , Bay City (Seal Beach) , Huntington Beach, Newport Beach and Redondo Beach. Harriman, who controlled the powerful Southern Pacific Railroad , was concerned with the competition that these new electric lines gave his steam railroad traffic, and had been prodding Huntington for joint ownership of the lines but Huntington refused to negotiate. In early 1903, Harriman proposed
13440-483: The lines in downtown Los Angeles to Santa Monica and down the coast to Redondo Beach to the Southern Pacific. In January 1907, the Hellman syndicate, after seeing that Huntington ran the Los Angeles Railway similarly to PE, continually expanding and not declaring dividends, sold their 45% stake in the Los Angeles Railway to Harriman and the Southern Pacific. The Covina line was completed in 1907, as well as
13580-539: 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
13720-489: The main dam is 3,000 cubic feet per second (85 m/s), maximum historical releases were 7,200 cubic feet per second (200 m/s) in 1983. The reservoir that Isabella Dam creates is called Lake Isabella . Water from Lake Isabella can be used in any of three ways. It is released into the Lower Kern River from the main dam, through the hydroelectric project in the main dam, or through the hydroelectric project in
13860-463: The main dam, modifications to California State Route 155 at the main dam's right abutment, and modifications at several recreation facilities north of the auxiliary dam. Construction began in 2018 and was completed in 2022. The area hosts over 30 designated campgrounds surrounding the reservoir, many within the Sequoia National Forest . The National Forest contains over 2,500 miles (4,000 km) of road and 850 miles (1,370 km) of trails, and hosts
14000-482: The mountains, and warmer than average temperatures in the area, the Upper Kern River was filling Lake Isabella faster than officials could lower it. The Lower Kern River was also running higher than normal, and flowing at up to 20 miles per hour (32 km/h) in some parts. State Route 178 , which travels through the canyon between Bakersfield and Lake Isabella, became unstable, and one lane was closed due to
14140-406: The new railways. Tensions between union leaders and like-minded Los Angeles businessmen were high from the early 1900s up through the 1920s. Strikes and boycotts troubled the Pacific Electric throughout those years until they reached the height of violence in the 1919 Streetcar Strike of Los Angeles . The efforts of organized labor simmered with the onset of World War I . Railroads were one part of
14280-437: 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
14420-468: The poor earnings of the interurban system, with profits of $ 151,000 in 1905 rising to $ 402,000 in 1907 (equivalent to $ 5.12 million and $ 13.1 million in 2023). However, in 1909, earnings were only $ 75,000. Huntington had begun long negotiations with Harriman about consolidating the Los Angeles electric railways beginning in 1907. There had always been a difference between the two men as to
14560-414: 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
14700-422: The popularity and utility of the system in an extended sequence in his 1924 film Girl Shy , where, after finding one Red Car too crowded, he commandeered another and drove at high speed through the streets of Culver City and Los Angeles. In response to a proposal to establish the first bus company in Los Angeles by William Gibbs McAdoo , Pacific Electric and the Los Angeles Railway proposed their own system,
14840-440: 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
14980-424: The purpose of the railway, with Huntington seeing the PE as a means to facilitate his real estate efforts, and Harriman seeing it as part of the Southern Pacific's overall transportation system in Southern California . Harriman left Huntington alone until 1910, when the former refused to allow the latter to run a line to San Diego that would have interfered with a competitive arrangement Harriman had worked out with
15120-492: The region attracting millions of workers. There were several years when the company's income statement showed a profit when gasoline and rubber were rationed and much of the populace depended on mass transit. At peak operation toward the end of the war, the PE dispatched over 10,000 trains daily and was a major employer in Southern California. However, the equipment in use was old and suffered from deferred maintenance. The nation's last interurban Railroad post office (RPO) service
15260-609: The remaining 20%. Huntington could expand the PE as he saw fit, but he was not to compete with existing SP lines. A byproduct of this sale was that Harriman sold the banking unit of his Wells Fargo Company to Hellman who merged it with his Nevada Bank operations and established the Pacific Coast's largest, most powerful bank. On June 6, 1903, Huntington created the Los Angeles Inter-Urban Railway, capitalized at $ 10 million (equivalent to $ 339 million in 2023), with plans to extend lines to Santa Ana , Newport Beach ,
15400-477: 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
15540-416: The risk to the public and property from floods, earthquakes, and seepage. Part of the plan included raising both dams approximately 16 feet (4.9 m), a new 900 feet (270 m) emergency spillway, and moving State Route 155 and State Route 178 above the new crest line. Changes made to the original plan also reduced impacts on recreation, biological resources, and water quality. The planners consulted with
15680-874: 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
15820-478: 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
15960-439: 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
16100-496: The secret winner. In May 1903, Huntington made an overnight trip to San Francisco and worked out an arrangement with Harriman. The Pacific Electric would get the Los Angeles Traction Lines, SP's San Gabriel Valley Rapid Transit Railway line, the 6th Street franchise, and some downtown trackage. In return, Harriman got 40.3% of PE stock, an amount equal to Huntington's, with Hellman, Borel and De Guigne owning
16240-488: 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,
16380-491: The south closed in 1958 as the Golden State/Santa Ana (Interstate 5) neared completion. The Los Angeles Metropolitan Transit Authority was established in 1951 to study the possibility of establishing a publicly owned monorail line running north from Long Beach to downtown Los Angeles and then west to Panorama City in the San Fernando Valley. In 1954, the agency's powers were expanded to allow it to propose
16520-400: 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
16660-679: 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
16800-671: 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
16940-781: 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
17080-664: 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
17220-523: 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
17360-454: The world, with 2,160 daily trains over 1,000 miles (1,600 km) of track. It operated to many destinations in Southern California, particularly to the south and east. The Southern Pacific now began to emphasize freight operations. From 1911, when revenue from freight was $ 519,226 ($ 17 million adjusted for inflation), freight revenue climbed to $ 1,203,956 in 1915 (equivalent to $ 36.3 million in 2023), 13% of total revenue. During
17500-485: 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
17640-621: 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
17780-405: The younger Huntington developed a close business relationship. The success of their San Francisco trolley adventure and Hellman's experience in financing some early Los Angeles trolley lines led them to invest in the purchase of some existing downtown Los Angeles lines which they began to standardize and organize into one network called the Los Angeles Railway . When his uncle Collis died, Henry lost
17920-672: Was built around the Temple Street horsecar, which was later upgraded to electric streetcar as part of the Yellow Car system. Highland Park was developed along the Figueroa Street trolley lines and railroads linking downtown Los Angeles and Pasadena. Huntington owned nearly all the stock in the Pacific Electric Land Company. West Hollywood was established by Moses Sherman and his partners of
18060-515: Was cut in 1938, Redondo Beach, Newport Beach, Sawtelle via San Vicente, and Riverside in 1940. When the San Bernardino Freeway opened in 1941 but was not yet connected to the Hollywood Freeway, while the "Four Way" overpass was being constructed, westbound car traffic from the SB freeway poured onto downtown streets near the present Union Station. PE's multiple car trains coming and going from Pasadena, Sierra Madre, and Monrovia/Glendora used those same streets
18200-499: Was decommissioned in 2018 and the easement through the Auxiliary Dam was sealed in February 2019. With more than 300,000 people living and working below the dams, primarily in the town of Lake Isabella and the city of Bakersfield, the U.S. Army Corps of Engineers ( USACE ) began a dam safety modification study (DSMS) in 2006 to address seismic, hydrologic (potential overtopping during an extreme flood event) and seepage issues at
18340-640: 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
18480-560: 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
18620-503: Was done to agriculture alone in the Tulare Lake Basin; the Kern River contributed almost half of the flow that caused the damage. The Sacramento District, under the direction of the district engineer, Lt. Col. Chambers, and by the authority of the 1936 Act, conducted a study of the area in 1937. Their study, completed in 1940, disclosed that roughly $ 750,000 (over $ 12 million today) in flood control benefits would be realized with
18760-610: Was later utilized when the Southern California RTD was designing and building the Metro Blue Line light rail line. The Blue Line, the first modern mass transit line in Los Angeles since the discontinuation of the Red Car service, was first opened in 1990. The few remaining trolley-coach routes and narrow gauge streetcar routes of the former Los Angeles Railway "Yellow Cars" were removed in early 1963. The public transportation system continued to be operated by
18900-459: Was of such great concern by the late 1930s that the influential Automobile Club of Southern California engineered an elaborate plan to create an elevated freeway-type Motorway System, a key aspect of which was the dismantling of the streetcar lines, replacing them with buses that could run on both local streets and on the new express roads. When the freeway system was planned in the 1930s the city planners planned to include interurban tracks in
19040-412: Was operated by PE on its San Bernardino Line. This was inaugurated comparatively late, on September 2, 1947. It left LA's new Union Station interurban yard on the west side of the terminal, turned north onto Alameda Street at 12:45 pm and reached San Bernardino at 4:40 pm, taking three hours for the trip while making postal stops en route as required. It did not operate on Sundays or holidays. This last RPO
19180-478: Was popular during the 1893 Columbian Exposition . In 1948, Congress appropriated funds to build a dam to prevent flooding of Bakersfield . The city had been flooded in 1867 and 1893. In 1950, while the dam was under construction, they experienced flooding measuring 30,000 cubic feet (850 m) of water per second. The dam was completed in March 1953. The U.S. Corps of Engineers built earthen dams across two forks of
19320-402: Was pulled off May 6, 1950. Aware that most new arrivals planned to stay in the region after the war, local municipal governments, Los Angeles County and the state agreed that a massive infrastructure improvement program was necessary. At that time politicians agreed to construct a web of freeways across the region. This was seen as a better solution than a new mass transit system or an upgrade of
19460-674: Was received in September 1942 to abandon the shuttle line to General Hospital which company officials said had been operating at a loss for several months. The Glendale line survived to the early 1950s due to the convenience of a subway into downtown Los Angeles and used the company's only modern equipment, a group of streamlined PCC cars. In 1940, Pacific Electric sold its Glendale , Burbank , and Pasadena operations to Pacific City Lines . San Bernardino operations were sold to San Bernardino Valley Transit. PE carried increased passenger loads during World War II, when Los Angeles County's population nearly doubled as war industries concentrated in
19600-584: 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,
