In economics , a common-pool resource ( CPR ) is a type of good consisting of a natural or human -made resource system (e.g. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike pure public goods , common pool resources face problems of congestion or overuse, because they are subtractable. A common-pool resource typically consists of a core resource (e.g. water or fish), which defines the stock variable , while providing a limited quantity of extractable fringe units, which defines the flow variable . While the core resource is to be protected or nurtured in order to allow for its continuous exploitation, the fringe units can be harvested or consumed.

138-473: Common-pool goods are typically regulated and nurtured in order to prevent demand from overwhelming supply and allow for their continued exploitation. Examples of common-pool resources include forests, man-made irrigation systems, fishing grounds, and groundwater basins. For instance, fishermen have an incentive to harvest as many fish as possible because if they do not, someone else will—so without management and regulation, fish stocks soon become depleted. And while

276-512: A Global Framework on Chemicals aiming to reduce pollution was agreed during an international conference in Bonn , Germany. The framework includes 28 targets, for example, to "end the use of hazardous pesticides in agriculture where the risks have not been managed" by 2035. Pollution has a cost. Manufacturing activities that cause air pollution impose health and clean-up costs on the whole of society. A manufacturing activity that causes air pollution

Sebastián Vizcaíno explored and mapped the coast of California in 1602 for New Spain , putting ashore in Monterey . Despite the on-the-ground explorations of California in the 16th century, Rodríguez's idea of California as an island persisted. Such depictions appeared on many European maps well into

552-575: A commodity until the 1849 California Gold Rush . From the 1820s, trappers and settlers from the United States and Canada began to arrive in Northern California. These new arrivals used the Siskiyou Trail , California Trail , Oregon Trail and Old Spanish Trail to cross the rugged mountains and harsh deserts in and surrounding California. The early government of the newly independent Mexico

690-433: A common property state, a common-pool resource appears as a private good to an outsider and as a common good to an insider of the community. The resource units withdrawn from the system are typically owned individually by the appropriators. A common property good is rivaled in consumption. Analysing the design of long-enduring CPR institutions, Elinor Ostrom identified eight design principles which are prerequisites for

828-451: A common-pool resource) is a particular social arrangement regulating the preservation, maintenance, and consumption of a common-pool resource. The use of the term "common property resource" to designate a type of good has been criticized, because common-pool resources are not necessarily governed by common property protocols. Examples of common-pool resources include irrigation systems, fishing grounds, pastures , forests , water or

966-476: A community are restricted to fishing in the territory held by that community. This is enforced by surreptitious violence towards interlopers. Fishermen in these exclusive territories catch significantly more and larger lobsters with less effort than those in areas where territories overlap. In the New York Bight region, a cooperative of trawl fishermen that specializes in harvesting whiting limits entry into

1104-552: A factor of calculating optimal levels. While a study puts the global mean loss of life expectancy (LLE; similar to YPLL ) from air pollution in 2015 at 2.9 years (substantially more than, for example, 0.3 years from all forms of direct violence), it also indicated that a significant fraction of the LLE is unavoidable in terms of current economical-technological feasibility such as aeolian dust and wildfire emission control. In markets with pollution, or other negative externalities in production,

1242-560: A free state, the "loitering or orphaned Indians", were de facto enslaved by their new Anglo-American masters under the 1850 Act for the Government and Protection of Indians . One of these de facto slave auctions was approved by the Los Angeles City Council and occurred for nearly twenty years. There were many massacres in which hundreds of indigenous people were killed by settlers for their land. Between 1850 and 1860,

1380-914: A health risk to animals. Motor vehicle emissions are one of the leading causes of air pollution. China , United States , Russia , India Mexico , and Japan are the world leaders in air pollution emissions. Principal stationary pollution sources include chemical plants , coal-fired power plants , oil refineries , petrochemical plants, nuclear waste disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.), PVC factories, metals production factories, plastics factories, and other heavy industry . Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides. About 400 million metric tons of hazardous wastes are generated each year. The United States alone produces about 250 million metric tons. Americans constitute less than 5% of

1518-654: A heritage of customary laws to regulate hunting. However, in the 1920s the railroads caused a large influx of non-native trappers who took advantage of the high fur prices and the indigenous people losing control of their territories. Both non-native and native trappers contributed to the decline of the beaver population, prompting conservation laws to be enacted after 1930 and outsiders being banned from trapping in James Bay. Eventually, Amerindian communities and family territories were legally recognized, and customary laws became enforceable. This restoration of local control allowed for

1656-539: A metropolis, Berlin did not emerge from a state of barbarism into civilization until after 1870. The primitive conditions were intolerable for a world national capital, and the Imperial German government brought in its scientists, engineers, and urban planners to solve the deficiencies and forge Berlin as the world's model city. A British expert in 1906 concluded that Berlin represented "the most complete application of science, order and method of public life," adding "it

1794-624: A modest home which in the 1960s cost $ 25,000 would cost half a million dollars or more in urban areas by 2005. More people commuted longer hours to afford a home in more rural areas while earning larger salaries in the urban areas. Speculators bought houses, expecting to make a huge profit in months, then rolling it over by buying more properties. Mortgage companies were compliant, as people assumed prices would keep rising. The bubble burst in 2007–8 as prices began to crash. Hundreds of billions in property values vanished and foreclosures soared, as financial institutions and investors were badly hurt. In

1932-436: A number of common pool resources throughout the world, Elinor Ostrom noticed that a number of them are governed by common property protocols — arrangements different from private property or state administration — based on self-management by a local community. Her observations contradict claims that common-pool resources must be privatized or else face destruction in the long run due to collective action problems leading to

2070-463: A part of Mexico. In 1846, the total settler population of the western part of the old Alta California had been estimated to be no more than 8,000, plus about 100,000 Native Americans, down from about 300,000 before Hispanic settlement in 1769. In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both

2208-712: A remote land rich in gold and pearls, inhabited by beautiful Black women who wore gold armor and lived like Amazons , as well as griffins and other strange beasts. Abbreviations of the state's name include CA, Cal., Calif., Califas , and US-CA . California was one of the most culturally and linguistically diverse areas in pre-Columbian North America . Historians generally agree that there were at least 300,000 people living in California prior to European colonization. The Indigenous peoples of California included more than 70 distinct ethnic groups , inhabiting environments ranging from mountains and deserts to islands and redwood forests. Living in these diverse geographic areas,

2346-411: A river might supply many cities with drinking water, manufacturing plants might be tempted to pollute the river if they were not prohibited from doing so by law because someone else would bear the costs. In California , where there is a huge demand for surface water but supplies are limited, common pool problems are exacerbated because the state does not manage groundwater basins at the state level. During

2484-721: A short break in 1862 when legislative sessions were held in San Francisco due to flooding in Sacramento . Once the state's Constitutional Convention had finalized its state constitution, it applied to the U.S. Congress for admission to statehood . On September 9, 1850, as part of the Compromise of 1850 , California became a free state and September   9 a state holiday . During the American Civil War (1861–1865), California sent gold shipments eastward to Washington in support of

2622-577: A significant issue in the United States in the early twentieth century, as progressive reformers took issue with air pollution caused by coal burning, water pollution caused by bad sanitation, and street pollution caused by the three million horses who worked in American cities in 1900, generating large quantities of urine and manure . As historian Martin Melosi notes, the generation that first saw automobiles replacing horses saw cars as "miracles of cleanliness". By

2760-476: A small amount that has been incinerating, virtually every piece of plastic that was ever made in the past still exists in one form or another. And since most of the plastics do not biodegrade in any meaningful sense, all that plastic waste could exist for hundreds or even thousands of years. If plastic production is not circumscribed, plastic pollution will be disastrous and will eventually outweigh fish in oceans. Carbon dioxide , while vital for photosynthesis ,

2898-545: A stable CPR arrangement: Common property systems typically function at a local level to prevent the overexploitation of a resource system from which fringe units can be extracted. In some cases, government regulations combined with tradable environmental allowances (TEAs) are used successfully to prevent excessive pollution, whereas in other cases — especially in the absence of a unique government being able to set limits and monitor economic activities — excessive use or pollution continue.

3036-596: A state Constitutional Convention was first held in Monterey. Among the first tasks of the convention was a decision on a location for the new state capital. The first full legislative sessions were held in San Jose (1850–1851). Subsequent locations included Vallejo (1852–1853), and nearby Benicia (1853–1854); these locations eventually proved to be inadequate as well. The capital has been located in Sacramento since 1854 with only

3174-458: Is a marvel of civic administration, the most modern and most perfectly organized city that there is." The emergence of great factories and consumption of immense quantities of coal gave rise to unprecedented air pollution , and the large volume of industrial chemical discharges added to the growing load of untreated human waste. Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881. Pollution became

3312-659: Is a negative externality and an example of problems that arise with open access goods. California California is a state in the Western United States , lying on the American Pacific Coast . It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With nearly 39   million residents across an area of 163,696 square miles (423,970 km ), it

3450-464: Is an example of a negative externality in production. A negative externality in production occurs "when a firm's production reduces the well-being of others who are not compensated by the firm." For example, if a laundry firm exists near a polluting steel manufacturing firm, there will be increased costs for the laundry firm because of the dirt and smoke produced by the steel manufacturing firm. If external costs exist, such as those created by pollution,

3588-424: Is highly dependent upon the type of resource involved. An effective strategy at one location, or of one particular resource, may not be necessarily appropriate for another. In The Challenge of Common-Pool Resources , Ostrom makes the case for adaptive governance as a method for the management of common-pool resources. Adaptive governance is suited to dealing with problems that are complex, uncertain and fragmented, as

3726-447: Is important that policymakers attempt to balance these indirect benefits with the costs of pollution in order to achieve an efficient outcome. It is possible to use environmental economics to determine which level of pollution is deemed the social optimum. For economists, pollution is an "external cost and occurs only when one or more individuals suffer a loss of welfare". There is a socially optimal level of pollution at which welfare

3864-436: Is maximized. This is because consumers derive utility from the good or service manufactured, which will outweigh the social cost of pollution until a certain point. At this point the damage of one extra unit of pollution to society, the marginal cost of pollution, is exactly equal to the marginal benefit of consuming one more unit of the good or service. Moreover, the feasibility of pollution reduction rates could also be

4002-415: Is not unusual. When accidents occur, some pollution sources, such as nuclear power stations or oil ships, can create extensive and potentially catastrophic emissions. Plastic pollution is choking our oceans by making plastic gyres, entangling marine animals, poisoning our food and water supply, and ultimately inflicting havoc on the health and well-being of humans and wildlife globally. With the exception of

4140-489: Is sometimes referred to as pollution, because raised levels of the gas in the atmosphere are affecting the Earth's climate. Disruption of the environment can also highlight the connection between areas of pollution that would normally be classified separately, such as those of water and air. Recent studies have investigated the potential for long-term rising levels of atmospheric carbon dioxide to cause slight but critical increases in

4278-575: Is the most populous U.S. state, the third-largest by area, and most populated subnational entity in North America . Prior to European colonization , California was one of the most culturally and linguistically diverse areas in pre-Columbian North America . European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire . The area became a part of Mexico in 1821, following its successful war for independence , but

4416-436: Is the largest of any U.S. state, with a $ 4.0 trillion gross state product as of 2024 . It is the largest sub-national economy in the world. California's agricultural industry has the highest output of any U.S. state, and is led by its dairy , almonds , and grapes . With the busiest port in the country ( Los Angeles ), California plays a pivotal role in the global supply chain, hauling in about 40% of goods imported to

4554-400: Is the management of common-pool resources. Ostrom outlines five basic protocol requirements for achieving adaptive governance. These include: A new proposal of the management of CPR is to develop autonomous organizations that are not completely privatized and controlled by government power, which led and supervised by the community to manage common-pool resources in addition to directly through

4692-848: Is triple the number of deaths caused by AIDS, tuberculosis and malaria combined, and 15 times higher than deaths caused by wars and other forms of human violence. The study concluded that "pollution is one of the great existential challenges of the Anthropocene era. Pollution endangers the stability of the Earth's support systems and threatens the continuing survival of human societies." Adverse air quality can kill many organisms, including humans. Ozone pollution can cause respiratory disease , cardiovascular disease , throat inflammation, chest pain, and congestion . A 2010 analysis estimated that 1.2 million people died prematurely each year in China alone because of air pollution. China's high smog levels can damage

4830-500: The Battle of Providencia near Los Angeles, he convinced each side that they had no reason to be fighting each other. As a result of Marsh's actions, they abandoned the fight, Micheltorena was defeated, and California-born Pio Pico was returned to the governorship. This paved the way to California's ultimate acquisition by the United States. In 1846, a group of American settlers in and around Sonoma rebelled against Mexican rule during

4968-631: The Bear Flag Revolt . Afterward, rebels raised the Bear Flag (featuring a bear, a star, a red stripe and the words "California Republic") at Sonoma. The Republic's only president was William B. Ide , who played a pivotal role during the Bear Flag Revolt. This revolt by American settlers served as a prelude to the later American military invasion of California and was closely coordinated with nearby American military commanders. The California Republic

Meanwhile, attracted to the mild Mediterranean climate, cheap land, and the state's variety of geography, filmmakers established the studio system in Hollywood in the 1920s. California manufactured 9% of US armaments produced during World War II , ranking third behind New York and Michigan . California easily ranked first in production of military ships at drydock facilities in San Diego, Los Angeles, and

Under its new American administration, California's first governor Peter Hardeman Burnett instituted policies that have been described as a state-sanctioned policy of elimination of California's indigenous people. Burnett announced in 1851 in his Second Annual Message to the Legislature: "That a war of extermination will continue to be waged between

In 1940, the Census Bureau reported California's population as 6% Hispanic, 2.4% Asian, and 90% non-Hispanic white. To meet the population's needs, engineering feats like the California and Los Angeles Aqueducts ; the Oroville and Shasta Dams ; and the Bay and Golden Gate Bridges were built. The state government adopted

Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases . The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade

6210-639: The atmosphere . A pasture, for instance, allows for a certain amount of grazing to occur each year without the core resource being harmed. In the case of excessive grazing, however, the pasture may become more prone to erosion and eventually yield less benefit to its users. Because the core resources are vulnerable, common-pool resources are generally subject to problems of congestion , overuse, pollution , and potential destruction unless harvesting or use limits are devised and enforced. Resource systems like pastoral areas, fishing grounds, forest areas are storage variables. Under favorable conditions, they can maximize

6348-653: The coast of California were the members of a Spanish maritime expedition led by Portuguese captain Juan Rodríguez Cabrillo in 1542. Cabrillo was commissioned by Antonio de Mendoza , the Viceroy of New Spain , to lead an expedition up the Pacific coast in search of trade opportunities; they entered San Diego Bay on September 28, 1542, and reached at least as far north as San Miguel Island . Privateer and explorer Francis Drake explored and claimed an undefined portion of

6486-588: The environment from the adverse effects of pollution, many nations worldwide have enacted legislation to regulate various types of pollution as well as to mitigate the adverse effects of pollution. At the local level, regulation usually is supervised by environmental agencies or the broader public health system . Different jurisdictions often have different levels regulation and policy choices about pollution. Historically, polluters will lobby governments in less economically developed areas or countries to maintain lax regulation in order to protect industrialisation at

6624-428: The free market equilibrium will not account for the costs of pollution on society . If the social costs of pollution are higher than the private costs incurred by the firm, then the true supply curve will be higher. The point at which the social marginal cost and market demand intersect gives the socially optimal level of pollution. At this point, the quantity will be lower and the price will be higher in comparison to

6762-412: The natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants , the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that

6900-616: The ozone layer , and hydrogen sulfides , which are capable of killing humans at concentrations of less than 1 part per thousand. Volcanic emissions also include fine and ultrafine particles which may contain toxic chemicals and substances such as arsenic , lead , and mercury . Wildfires , which can be caused naturally by lightning strikes , are also a significant source of air pollution. Wildfire smoke contains significant quantities of both carbon dioxide and carbon monoxide, which can cause suffocation . Large quantities of fine particulates are found within wildfire smoke as well, which pose

The Portolá expedition of 1769–70 was a pivotal event in the Spanish colonization of California, resulting in the establishment of numerous missions, presidios , and pueblos . The military and civil contingent of the expedition was led by Gaspar de Portolá , who traveled over land from Sonora into California, while the religious component was headed by Junípero Serra , who came by sea from Baja California . In 1769, Portolá and Serra established Mission San Diego de Alcalá and

7452-482: The 1992 Rodney King riots. California was the hub of the Black Panther Party , known for arming African Americans to defend against racial injustice. Mexican, Filipino, and other migrant farm workers rallied in the state around Cesar Chavez for better pay in the 1960s and 70s. During the 20th century, two great disasters happened: the 1906 San Francisco earthquake and 1928 St. Francis Dam flood remain

7590-1005: The 19th and 20th centuries until the emergence of environmental regulation and pollution policy in the later half of the 20th century. Sites where historically polluting industries released persistent pollutants may have legacy pollution long after the source of the pollution is stopped. Major forms of pollution include air pollution , water pollution , litter , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , light pollution , and visual pollution . Pollution has widespread consequences on human and environmental health , having systematic impact on social and economic systems. In 2019, pollution killed approximately nine million people worldwide (about one in six deaths that year); about three-quarters of these deaths were caused by air pollution . A 2022 literature review found that levels of anthropogenic chemical pollution have exceeded planetary boundaries and now threaten entire ecosystems around

8556-609: The San Francisco Bay Area. Due to the hiring opportunities California offered during the conflict, the population multiplied from the immigration it received due to the work in its war factories, military bases, and training facilities. After World War II, California's economy expanded due to strong aerospace and defense industries, whose size decreased following the end of the Cold War . Stanford University began encouraging faculty and graduates to stay instead of leaving

California is the home of Hollywood , the oldest and one of the largest film industries in the world, profoundly influencing global entertainment. The San Francisco Bay and the Greater Los Angeles areas are seen as the centers of the global technology and U.S. film industries, respectively. The Spaniards gave

8970-454: The Union . However, due to the existence of a large contingent of pro-South sympathizers within the state, the state was not able to muster any full military regiments to send eastwards to officially serve in the Union war effort. Still, several smaller military units within the Union army, such as the "California 100 Company" , were unofficially associated with the state of California due to a majority of their members being from California. At

In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists, economists, and policymakers from more than 120 countries, confirmed that humans have been the primary cause of global warming since 1950. Humans have ways to cut greenhouse gas emissions and avoid

9246-411: The amount of pollution that they are producing. The associated costs of doing this are called abatement costs, or marginal abatement costs if measured by each additional unit. In 2005 pollution abatement capital expenditures and operating costs in the US amounted to nearly $ 27 billion. The Pure Earth , an international non-for-profit organization dedicated to eliminating life-threatening pollution in

His letters were read, reread, passed around, and printed in newspapers throughout the country, and started the first wagon trains rolling to California. After ushering in the period of organized emigration to California, Marsh became involved in a military battle between the much-hated Mexican general, Manuel Micheltorena and the California governor he had replaced, Juan Bautista Alvarado. At

9798-429: The case if the producer were to receive payment for the external benefits to others. Goods and services that involve negative externalities in production, such as those that produce pollution, tend to be overproduced and underpriced since the externality is not being priced into the market. Pollution can also create costs for the firms producing the pollution. Sometimes firms choose, or are forced by regulation, to reduce

9936-619: The complexity of CPR dilemmas and highlight the nuanced interplay between individual strategies, collective action, and resource sustainability, providing a multifaceted understanding of cooperation and norm internalization in the management of communal resources. In economics, open access resources are, for the most part, rivalrous, non-excludable goods. This makes them similar to common goods during times of prosperity. Unlike many common goods, open access goods require little oversight or may be difficult to restrict access. However, as these resources are first come, first served, they may be affected by

10074-536: The conquest include the Battle of San Pasqual and the Battle of Dominguez Rancho in Southern California, as well as the Battle of Olómpali and the Battle of Santa Clara in Northern California. After a series of defensive battles in the south, the Treaty of Cahuenga was signed by the Californios on January 13, 1847, securing a censure and establishing de facto American control in California. Following

10212-639: The consequences of global warming, a major climate report concluded. But to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the UN's Intergovernmental Panel on Climate Change (IPCC). Pollution affects humans in every part of the world. An October 2017 study by the Lancet Commission on Pollution and Health found that global pollution, specifically toxic air, water, soil and workplaces, kills nine million people annually, which

10350-560: The contaminants have an anthropogenic source – that is, a source created by human activities, such as manufacturing , extractive industries , poor waste management , transportation or agriculture . Pollution is often classed as point source (coming from a highly concentrated specific site, such as a factory , mine , construction site ), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff ). Many sources of pollution were unregulated parts of industrialization during

10488-426: The core resource and allocate the fringe resources through complex community norms of consensus decision-making . Common resource management has to face the difficult task of devising rules that limit the amount, timing, and technology used to withdraw various resource units from the resource system. Setting the limits too high would lead to overuse and eventually to the destruction of the core resource while setting

10626-445: The cost of human and environmental health . The modern environmental regulatory environment has its origins in the United States with the beginning of industrial regulations around Air and Water pollution connected to industry and mining during the 1960s and 1970s. Pollution control is a term used in environmental management . It refers to the control of emissions and effluents into air, water or soil. Without pollution control,

10764-535: The deadliest in U.S. history. Although air pollution has been reduced, health problems associated with pollution continue. Brown haze known as " smog " has been substantially abated after federal and state restrictions on automobile exhaust. An energy crisis in 2001 led to rolling blackouts , soaring power rates, and the importation of electricity from neighboring states. Southern California Edison and Pacific Gas and Electric Company came under heavy criticism. Housing prices in urban areas continued to increase;

10902-552: The developing world, issues an annual list of some of the world's most polluting industries. Below is the list for 2016: A 2018 report by the Institute for Agriculture and Trade Policy and GRAIN says that the meat and dairy industries are poised to surpass the oil industry as the world's worst polluters. The textile industry is one of the largest polluters in the globalized world of mostly free market dominated socioeconomic systems. Chemically polluted textile wastewater degrades

11040-506: The dynamics and dilemmas associated with communal resource management. A foundational work introduced a conceptual framework that elucidates the strategic content of CPR dilemmas, demonstrating how theoretical constructs, such as the Prisoner's Dilemma and coordination games, apply to these behavioral challenges. Further, field experiments involving specific ecological features of CPRs, such as water irrigation, forestry, and fisheries, have revealed

11178-617: The earlier extreme cases of water quality problems with the Great Stink on the Thames of 1858, which led to the construction of the London sewerage system soon afterward. Pollution issues escalated as population growth far exceeded the viability of neighborhoods to handle their waste problem. Reformers began to demand sewer systems and clean water. In 1870, the sanitary conditions in Berlin were among

11316-510: The environment with large amounts of microplastics and has been identified in one review as the industry sector producing the largest amount of pollution. A campaign of big clothing brands like Nike, Adidas and Puma to voluntarily reform their manufacturing supply chains to commit to achieving zero discharges of hazardous chemicals by 2020 (global goal) appears to have failed. Outdoor air pollution attributable to fossil fuel use alone causes ~3.61 million deaths annually, making it one of

11454-404: The exploitation of the most used resources will effectively increase the rate of resource supply and reduce the rate of resource consumption and individual demand. (3) Group identity. When people in a community have a strong sense of group identity, it helps to manage CPR within the community. Common Pool Resource (CPR) games have been a focal point in experimental research, providing insights into

11592-584: The first fires . According to a 1983 article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires." Metal forging appears to be a key turning point in the creation of significant air pollution levels outside the home. Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman, and Chinese metal production. The burning of coal and wood, and

11730-401: The flow without harming the total storage volume and the entire resource system. Different from the resource system, the resource unit is the amount that an individual occupies or uses from the resource system, such as the total amount of fish caught in a fishing ground, the amount of feed consumed by livestock in pastoral areas. A resource system allows multiple people or enterprise to produce at

11868-455: The free market equilibrium. Therefore, the free market outcome could be considered a market failure because it "does not maximize efficiency". This model can be used as a basis to evaluate different methods of internalizing the externality, such as tariffs , a Pigouvian tax (such as a carbon tax ) and cap and trade systems. Air pollution has always accompanied civilizations. Pollution started from prehistoric times , when man created

12006-694: The fringe variable as long as the stock variable is not compromised, providing an optimum amount of consumption. However, consumption exceeding the fringe value reduces the stock variable, which in turn decreases the flow variable. If the stock variable is allowed to regenerate then the fringe and flow variables may also recover to initial levels, but in many cases the loss is irreparable. Common-pool resources may be owned by national, regional or local governments as public goods , by communal groups as common property resources , or by private individuals or corporations as private goods . When they are owned by no one, they are used as open access resources . Having observed

12144-431: The government and bureaucracy can be abused. The community is responsible for supervising and administering CPR under an autonomous management system, the characteristics of a community can affect how CPR is managed. (1) the size of the community. The level of cooperation decreases as the number of community members grows; (2) Allocation mechanism for CPR. Encouraging the exploitation of the least used resources and reducing

12282-481: The government and the free market. There are many factors that may affect the formation and development of these kinds of autonomous organizations. Effectively identifying the influencing factors of the autonomous management system of CPRs increasing the feasibility of the system, and it is more conducive to the sustainable use of resources as well. In general, there are four variables that are very important for local common-pool resource management: (1) characteristics of

12420-618: The government to adequately sustain the populations living on them. As a result, settler colonialism was a calamity for indigenous people. Several scholars and Native American activists, including Benjamin Madley and Ed Castillo , have described the actions of the California government as a genocide , as well as the 40th governor of California Gavin Newsom . Benjamin Madley estimates that from 1846 to 1873, between 9,492 and 16,092 indigenous people were killed, including between 1,680 and 3,741 killed by

12558-551: The human body and cause various diseases. In 2019, air pollution caused 1.67 million deaths in India (17.8% of total deaths nationally). Studies have estimated that the number of people killed annually in the United States could be over 50,000. A study published in 2022 in GeoHealth concluded that energy-related fossil fuel emissions in the United States cause 46,900–59,400 premature deaths each year and PM2.5-related illness and death costs

12696-472: The impact of various resource-specific dynamics on collective action and resource management. Additionally, a study explored the external validity of CPR laboratory experiments within the context of artisanal benthic fisheries in Chile, revealing a correlation between cooperative behaviors exhibited in laboratory settings and those in real-world co-managed and open-access fisheries. These studies collectively underscore

12834-410: The indigenous peoples developed complex forms of ecosystem management, including forest gardening to ensure the regular availability of food and medicinal plants . This was a form of sustainable agriculture . To mitigate destructive large wildfires from ravaging the natural environment, indigenous peoples developed a practice of controlled burning . This practice was recognized for its benefits by

12972-556: The interior and north of California. The Anza expedition selected numerous sites for missions, presidios, and pueblos, which subsequently would be established by settlers. Gabriel Moraga , a member of the expedition, would also christen many of California's prominent rivers with their names in 1775–1776, such as the Sacramento River and the San Joaquin River . After the expedition, Gabriel's son, José Joaquín Moraga , would found

13110-524: The largest dam removal and river restoration project in US history was announced for the Klamath River , as a win for California tribes. Covering an area of 163,696 sq mi (423,970 km ), California is the third-largest state in the United States in area, after Alaska and Texas . California is one of the most geographically diverse states in the union and is often geographically bisected into two regions, Southern California , comprising

13248-405: The limits too low would unnecessarily reduce the benefits obtained by the users. In common property systems, access to the resource is not free and common-pool resources are not public goods . While there is relatively free but monitored access to the resource system for community members, there are mechanisms in place which allow the community to exclude outsiders from using its resource. Thus, in

13386-661: The local fishery and establishes catch quotas among members. These quotas are based on regional market sales estimations and attempt to encourage initiative while discouraging “free-riding.” They limit entry to the whiting grounds and markets through a closed membership policy and by controlling the dock space. Due to these methods, they have access to the best whiting grounds, dominate the market during winter, and can maintain relatively high prices through supply management. The fishermen consider this type of self-regulation both flexible and effective in maintaining sustainable use. A common property rights regime system (not to be confused with

13524-404: The manufacturer will choose to produce more of the product than would be produced if the manufacturer were required to pay all associated environmental costs. Because responsibility or consequence for self-directed action lies partly outside the self, an element of externalization is involved. If there are external benefits, such as in public safety , less of the good may be produced than would be

13662-788: The middle of the state lies the California Central Valley , bounded by the Sierra Nevada in the east, the coastal mountain ranges in the west, the Cascade Range to the north and by the Tehachapi Mountains in the south. The Central Valley is California's productive agricultural heartland. Divided in two by the Sacramento-San Joaquin River Delta , the northern portion, the Sacramento Valley serves as

13800-410: The most frequent soil contaminants. A series of press reports published in 2001, culminating in the publication of the book Fateful Harvest, revealed a widespread practise of recycling industrial leftovers into fertilizer, resulting in metal poisoning of the soil. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from

13938-421: The name Las Californias to the peninsula of Baja California (in modern-day Mexico). As Spanish explorers and settlers moved north and inland, the region known as California , or Las Californias , grew. Eventually it included lands north of the peninsula, Alta California , part of which became the present-day U.S. state of California. A 2017 state legislative document states, "Numerous theories exist as to

14076-451: The nation $ 537–$ 678 billion annually. In the US, deaths caused by coal pollution were highest in 1999, but decreased sharply after 2007. The number dropped by about 95% by 2020, as coal plants have been closed or have scrubbers installed. In 2019, water pollution caused 1.4 million premature deaths. Contamination of drinking water by untreated sewage in developing countries is an issue, for example, over 732 million Indians (56% of

14214-546: The nation's second- and fifth-most populous urban regions , with 19 million and 10 million residents respectively. Los Angeles is the state's most populous city and the nation's second-most ; California's capital is Sacramento . The state's diverse geography ranges from the Pacific Coast and metropolitan areas in the west to the Sierra Nevada mountains in the east, and from the redwood and Douglas fir forests in

14352-554: The natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard. The usefulness of the natural resource is usually impaired by the presence of pollutants and contaminants." In contrast, the United Nations considers pollution to be the "presence of substances and heat in environmental media (air, water, land) whose nature, location, or quantity produces undesirable environmental effects." The major forms of pollution are listed below along with

14490-519: The northwest to the Mojave Desert in the southeast. Two-thirds of the nation's earthquake risk lies in California. The Central Valley , a fertile agricultural area, dominates the state's center. The large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains . Droughts and wildfires are an ongoing issue. California's economy

14628-401: The origin and meaning of the word 'California, ' " and that all anyone knows is the name was added to a map by 1541 "presumably by a Spanish navigator." The name most likely derived from the mythical island of California in the fictional story of Queen Calafia , as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo . Queen Calafia's kingdom was said to be

14766-427: The overuse of the core resource ( see also Tragedy of the commons ). Common property systems of management arise when users acting independently threaten the total net benefit from common-pool resource. In order to maintain the resources, protocols coordinate strategies to maintain the resource as a common property instead of dividing it up into parcels of private property . Common property systems typically protect

14904-439: The particular contaminants relevant to each of them: One of the most significant natural sources of pollution are volcanoes , which during eruptions release large quantities of harmful gases into the atmosphere. Volcanic gases include carbon dioxide, which can be fatal in large concentrations and contributes to climate change , hydrogen halides which can cause acid rain , sulfur dioxides, which are harmful to animals and damage

15042-497: The phenomenon of the tragedy of the commons . Two possibilities may follow: a common property or an open access system. However, in a different setting, such as fishing, there will be drastically different consequences. Since fish are an open access resource, it is relatively simple to fish and profit. If fishing becomes profitable, there will be more fishers and fewer fish. Fewer fish lead to higher prices which will lead again to more fishers, as well as lower reproduction of fish. This

15180-414: The population of San Francisco increased from 500 to 150,000. The seat of government for California under Spanish and later Mexican rule had been located in Monterey from 1777 until 1845. Pio Pico, the last Mexican governor of Alta California, had briefly moved the capital to Los Angeles in 1845. The United States consulate had also been located in Monterey, under consul Thomas O. Larkin . In 1849,

15318-1348: The population) and over 92 million Ethiopians (92.9% of the population) do not have access to basic sanitation . In 2013 over 10 million people in India fell ill with waterborne illnesses in 2013, and 1,535 people died, most of them children. As of 2007 , nearly 500 million Chinese lack access to safe drinking water. Acute exposure to certain pollutants can have short and long term effects. Oil spills can cause skin irritations and rashes . Noise pollution induces hearing loss , high blood pressure , stress , and sleep disturbance . Mercury has been linked to developmental deficits in children and neurologic symptoms. Older people are significantly exposed to diseases induced by air pollution . Those with heart or lung disorders are at additional risk. Children and infants are also at serious risk. Lead and other heavy metals have been shown to cause neurological problems, intellectual disabilities and behavioural problems. Chemical and radioactive substances can cause cancer and birth defects . The health impacts of pollution have both direct and lasting social consequences. A 2021 study found that exposure to pollution causes an increase in violent crime. A 2019 paper linked pollution to adverse school outcomes for children. A number of studies show that pollution has an adverse effect on

15456-550: The presence of many horses in concentrated areas made the cities the primary sources of pollution. King Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke became a problem; the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow . The Industrial Revolution gave birth to environmental pollution as we know it today. London also recorded one of

15594-414: The prevention of urban runoff . Policy , law and monitoring/transparency/ life-cycle assessment -attached economics could be developed and enforced to control pollution. A review concluded that there is a lack of attention and action such as work on a globally supported "formal science – policy interface", e.g. to " inform intervention, influence research, and guide funding". In September 2023

15732-465: The productivity of both indoor and outdoor workers. Pollution has been found to be present widely in the natural environment . A 2022 study published in Environmental Science & Technology found that levels of anthropogenic chemical pollution have exceeded planetary boundaries and now threaten entire ecosystems around the world. There are a number of effects of this: To protect

15870-710: The pueblo of San Jose in 1777, making it the first civilian-established city in California. During this same period, sailors from the Russian Empire explored along the northern coast of California. In 1812, the Russian-American Company established a trading post and small fortification at Fort Ross on the North Coast . Fort Ross was primarily used to supply Russia's Alaskan colonies with food supplies. The settlement did not meet much success, failing to attract settlers or establish long term trade viability, and

16008-555: The quality of the soil and water . The pollution comes from the type of conduct of chemical treatments used e.g., in pretreatment, dyeing, printing, and finishing operations that many or most market-driven companies use despite "eco-friendly alternatives". Textile industry wastewater is considered to be one the largest polluters of water and soil ecosystems , causing "carcinogenic, mutagenic, genotoxic, cytotoxic and allergenic threats to living organisms". The textile industry uses over 8000 chemicals in its supply chain, also polluting

16146-465: The races until the Indian race becomes extinct must be expected. While we cannot anticipate the result with but painful regret, the inevitable destiny of the race is beyond the power and wisdom of man to avert." As in other American states, indigenous peoples were forcibly removed from their lands by American settlers , like miners, ranchers, and farmers. Although California had entered the American union as

16284-446: The resource; (2) characteristics of the resource-dependent group; (3) institutional model of resource management; (4) the relationship between groups, external forces, and authorities. The government, market and interest groups are all considered as external forces that have an impact on CPR management system. Changes in market demand for CPR, in particular, technological innovation increases productivity and lowers costs, which undermines

16422-400: The same time, and the process of using common-pool resources can be performed simultaneously by multiple occupants. However, the resource unit cannot be used by multiple people or enterprises at the same time. The use of many common-pool resources, if managed carefully, can be extended because the resource system forms a negative feedback loop, where the stock variable continually regenerates

16560-644: The state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882 Chinese Exclusion Act . Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which

16698-511: The state on March 4, 2020, and remained in effect until Governor Gavin Newsom ended it in February 2023. A mandatory statewide stay-at-home order was issued on March 19, 2020, which was ended in January 2021. Cultural and language revitalization efforts among indigenous Californians have progressed among tribes as of 2022. Some land returns to indigenous stewardship have occurred. In 2022,

16836-515: The state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Middle Easterns, Chinese and other immigrants during the great California gold rush . By the time of California's application for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854, more than 300,000 settlers had come. Between 1847 and 1870,

16974-614: The state, and develop a high-tech region, now known as Silicon Valley . As a result of this, California is a world center of the entertainment and music industries, of technology, engineering, and the aerospace industry, and as the US center of agricultural production. Just before the Dot Com Bust , California had the fifth-largest economy in the world. In the mid and late twentieth century, race-related incidents occurred. Tensions between police and African Americans, combined with unemployment and poverty in inner cities, led to riots, such as

17112-407: The sustainability of the management system. In order to develop more resources, resource owners may seek to change the ownership of resources in the form of cooperation with the government, privatize CPR or even cancel the protection of CPR ownership by regulations. Such institutional changes prevent the implementation of policies that are beneficial to the majority of the population, while the power of

17250-504: The ten southernmost counties, and Northern California , comprising the 48 northernmost counties. It is bordered by Oregon to the north, Nevada to the east and northeast, Arizona to the southeast, the Pacific Ocean to the west and shares an international border with the Mexican state of Baja California to the south (with which it makes up part of The Californias region of North America , alongside Baja California Sur ). In

17388-407: The time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the first transcontinental railroad was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state

17526-535: The top contributors to human death , beyond being a major driver of climate change whereby greenhouse gases are considered per se as a form of pollution (see above ) . Society derives some indirect utility from pollution; otherwise, there would be no incentive to pollute. This utility may come from the consumption of goods and services that inherently create pollution (albeit the level can vary) or lower prices or lower required efforts (or inconvenience) to abandon or substitute these goods and services. Therefore, it

17664-557: The transition from Spanish colonial rule to independent Mexican rule. In 1821, the Mexican War of Independence gave the Mexican Empire (which included California) independence from Spain. For the next 25 years, Alta California remained a remote, sparsely populated, northwestern administrative district of the newly independent country of Mexico, which shortly after independence became a republic. The missions , which controlled most of

17802-538: The watershed of the Sacramento River , while the southern portion, the San Joaquin Valley is the watershed for the San Joaquin River . Both valleys derive their names from the rivers that flow through them. With dredging, the Sacramento and the San Joaquin Rivers have remained deep enough for several inland cities to be seaports . Pollution Pollution is the introduction of contaminants into

17940-589: The wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfills that may have been subject to little control in the U.S. or EU. There have also been some unusual releases of polychlorinated dibenzodioxins , commonly called dioxins for simplicity, such as TCDD . Pollution can also occur as a result of natural disasters. Hurricanes, for example, frequently result in sewage contamination and petrochemical spills from burst boats or automobiles. When coastal oil rigs or refineries are involved, larger-scale and environmental damage

18078-458: The world. Pollutants frequently have outsized impacts on vulnerable populations, such as children and the elderly, and marginalized communities, because polluting industries and toxic waste sites tend to be collocated with populations with less economic and political power. This outsized impact is a core reason for the formation of the environmental justice movement , and continues to be a core element of environmental conflicts , particularly in

18216-492: The worst in Europe. August Bebel recalled conditions before a modern sewer system was built in the late 1870s: Waste-water from the houses collected in the gutters running alongside the curbs and emitted a truly fearsome smell. There were no public toilets in the streets or squares. Visitors, especially women, often became desperate when nature called. In the public buildings the sanitary facilities were unbelievably primitive....As

18354-541: Was abandoned by 1841. During the War of Mexican Independence , Alta California was largely unaffected and uninvolved in the revolution, though many Californios supported independence from Spain , which many believed had neglected California and limited its development. Spain's trade monopoly on California had limited local trade prospects. Following Mexican independence, California ports were freely able to trade with foreign merchants. Governor Pablo Vicente de Solá presided over

18492-486: Was ceded to the United States in 1848 after the Mexican–American War . The California gold rush started in 1848 and led to social and demographic changes, including depopulation of Indigenous tribes. The western portion of Alta California was then organized and admitted as the 31st state in 1850 , as a free state , following the Compromise of 1850 . The Greater Los Angeles and San Francisco Bay areas are

18630-536: Was extremely well suited to fruit cultivation and agriculture in general. Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere. In the nineteenth century, a large number of migrants from China traveled to

18768-607: Was highly unstable, and in a reflection of this, from 1831 onwards, California also experienced a series of armed disputes, both internal and with the central Mexican government. During this tumultuous political period Juan Bautista Alvarado was able to secure the governorship during 1836–1842. The military action which first brought Alvarado to power had momentarily declared California to be an independent state, and had been aided by Anglo-American residents of California, including Isaac Graham . In 1840, one hundred of those residents who did not have passports were arrested, leading to

18906-714: Was not usually the purpose of these small-scale battles. Men and women generally had different roles in society. Women were often responsible for weaving, harvesting, processing, and preparing food, while men for hunting and other forms of physical labor. Most societies also had roles for people whom the Spanish referred to as joyas , who they saw as "men who dressed as women". Joyas were responsible for death , burial , and mourning rituals , and they performed women's social roles. Indigenous societies had terms such as two-spirit to refer to them. The Chumash referred to them as 'aqi. The early Spanish settlers detested and sought to eliminate them. The first Europeans to explore

19044-494: Was short-lived; the same year marked the outbreak of the Mexican–American War (1846–1848). Commodore John D. Sloat of the United States Navy sailed into Monterey Bay in 1846 and began the U.S. military invasion of California , with Northern California capitulating in less than a month to the United States forces. In Southern California, Californios continued to resist American forces. Notable military engagements of
