Imperial

Imperial (: El Imperio) is a province in the southwestern region of Sierra. Imperial is the 17th largest and 20th most populous of the 23 provinces in Sierra. The capital of Imperial is, while the largest city is. The province is roughly divided in half by the. The province to the west of the river is considered a part of the Southwest Corridor and the California region, while the province to the east is considered a part of southeastern Sierra and the Arizona region. Imperial shares borders with the Inland Empire and Maricopa to the north, Laguna to the west, Maricopa and Sonora to the east, and Pacífico Norte to the south.

Prior to European exploration and colonization, Imperial sustained a significant population of various Native Sierran tribes including the and the. In the 17th century, Imperial was claimed by Spain, and became an integral part of. The area remained largely undisturbed under Spanish, and then Mexican control. After the Mexican-American War, Imperial became part of the independent California Republic, and was a constituent part of the States of Laguna and Maricopa. In the late 19th century, Imperial experienced a population boom as a comprehensive irrigation system developed. In 1907, Parliament partitioned Eastern Laguna and Southern Maricopa to create the new province of Imperial.

Imperial is situated primarily in the but features varied topography. The province is straddled with several major mountain ranges including the and, along with large valleys such as the. It is home to most of Sierra's largest lake, the. Although Imperial is a landlocked, desert province, the Colorado River and the aqueducts built around it has allowed the province to support a large agricultural sector. The valleys along the river produce one of the world's most economically productive agricultural areas, and are crucial to the province's local economy. Thanks to the river, a significant portion of the land are. Many areas along the river are protected by the federal and provincial government, and have large, thriving ecosystems, some harboring millions of members of migratory bird species across North America each year. It is one of the world's leading producers in, , , , and. It is also one of the top producers in various species of grass, which is essential for sustaining the nation's dairy and livestock industries. Imperial is home to the largest Anglo-American aquaculture farm for catfish and other species west of the.

Imperial produces over two-thirds of the vegetables and fruits consumed in Anglo-America during the winters, giving the province the nickname, the "Winter Garden". Agriculture remains the primary source of economic activity in the province, with secondary industries in tourism, geothermal energy, chemical manufacturing, and mining. In recent years, thanks to intensive restoration efforts to the Salton Sea, the province has experienced a recent boom in real estate development and economic opportunities in an increasingly globalizing world. The province is culturally close to its neighbors, the Pacíficos, and has the second-highest proportion of Hispanics among all PSAs after Sonora. Nonetheless, Imperial features an increasingly diversified ethnic markup, including non-Hispanic whites, Asian Sierrans, African Sierrans, and Native Sierrans.

Etymology
The name "Imperial" derives from the that is located in the western region of the province, and where the capital,, is located. The valley itself received its name from the, a subsidiary of the , that was based in the area. The company was responsible for much of the agricultural development of Imperial and the Colorado Desert during the late 19th century and early 20th century. Officially, as defined by the Constitution of Imperial, Imperial is known as the "Province of Imperial", and its citizens as "Imperials".

Historically, Imperial was simply known as "Colorado", in reference to the major river which flowed through the desert and drained from the delta into the. While there was small-scale settlements along the river south of the area in the Sierran territory of Pacífico Norte, development in modern-day Imperial west of the river was minimal. East of the river however, the area was home to several settlements which were built along the, a major route for Anglo-Americans traveling to and fro Sierra. The area became associated with the name, "Yuma", after one of its major settlements, and was substantially developed by the time it was incorporated into the new province of Imperial. Two of Imperial's counties, Colorado and Yuma, carry on these legacies, and are situated roughly where the names were applied respectively. When the province was originally established, its full and complete name was to be the "Province of Imperial Valley, the Colorado, and Yuma", but was the latter two historical names were dropped by 1929 as it was deemed "cumbersome" by provincial legislators and voters.

Occasionally, Imperial and its northern neighbor, the Inland Empire, have been confused for one another due to the similarity of their names (Imperial and the Inland Empire). Most commonly, people from the Inland Empire are distinguished as Inlanders while people from Imperial as Imperials. However, the term Imperial has also been applied to people from the Inland Empire, owing to the confusion of both province's similar terminologies. Occasionally, the article "the" has been applied to the province as in The Imperial for purposes of clarity.

Geography
Imperial has a total area of 10,001 sq mi (25,902 km$2$), making it slightly larger than the island nation of and the UC territory, and slightly smaller than the countries of  and. Imperial is situated in the southern central portion of federal Sierra, and is divided between the California and Arizona mega-regions along the Colorado River. The province shares borders with the Inland Empire and Maricopa to the north, Maricopa and Sonora to the east, Pacífico Norte to the south, and Laguna to the west. It is the 17th largest province in Sierra. The western half of Imperial consists of and the, with a significant portion of this area falling into the  region. Much of the region is below sea level, especially around the where the  is also located. The Salton Sea is Sierra's second largest lake, after the in the. There are several mountain ranges in the region, the largest of which are the which are due northeast of the Salton Sea. The mountains run in a northwest-southeast orientation and serves as the northeastern boundary of the, a large active tectonic spanning much of western Imperial. The famous lies west of the Chocolate Mountains, and southeast of the Salton Sea. The region is prone to frequent due to its location along the boundary between the  and the  along the  and the. The eastern half of Imperial is dominated by the and is considerably rockier, and more topographically varied than the western side. The region is noted for its alternating series of mountain ranges and valleys, as well as isolated mountains in otherwise uniformly low-lying areas, known as. Notable mountain ranges in this section of the province include the and the.

Climate
Generally, Imperial has a (: BWh), characterized by hot, dry, and sunny weather year-round. The climate is a result of several factors, including the, a persistent year-round , which occurs due to the province's location within the subtropics (roughly 33° N), as well as its location within the western, continental portion of the North American continent (along the eastern ocean basin of the Pacific). Because of its inland position, the area does not benefit from the that most of Western Sierra experiences. Some precipitation occurs during the wintertime when the subtropical high shifts southward towards Los Pacíficos, and a comes towards the area, bringing moisture. In eastern Imperial, the region gets additional rainfall during the late summer, usually between July and mid-September, from the. The monsoon is the result of a shift in prevailing winds along the which brings moisture to the otherwise dry area.

Flora
Despite being predominantly dry desert, Imperial is home to over 2,000 native plant species, and the Colorado River Delta remains an ecological hotspot. The plant life in Imperial have adapted to not only survive but flourish in the Sonoran Desert, and is sustained by the desert's biannual precipitation patterns. The Sonoran Desert in Imperial alone is home to more plant species than any other desert in the world.

Various notable species live in Imperial including the world famous {{W|saguaro cactus}} (Carnegiea gigantea), which is commonly found in eastern Imperial. Other cacti that grow in the province include the spiny {{W|Cylindropuntia|cholla}} (Cylindropuntia spp.), {{W|Optunia basilaris|beavertail}} (Opuntia basilaris), {{W|Echinocereus|hedgehog}} (Echinocereus spp.), {{W|Ferocactus wislenzi|fishhook}} (Ferocactus wislizeni), {{W|Opuntia|prickly pear}} (Opuntia spp.), {{W|Peniocereus|nightblooming cereus}} (Peniocereus spp.), and {{W|Stenocereus thurberi|organ pipe}} (Stenocereus thurberi).

In addition to species from the cacti family, there are members of the {{W|agave}}, {{W|Areacaceae|palm}}, {{W|legume}}, and other families. Seasonally, during the early spring, a large assortment of {{W|wildflower|wildflowers}} bloom across the desert floor. The {{W|Anza-Borrego Desert State Park|Anza-Borrego Desert Provincial Park}} is particularly famous for its annual wildflower fields, and are made possible by late winter precipitation. Wildflowers include the {{W|Abronia villosa|desert sand verbena}} (Abronia villosa), {{W|Geraea canescens|desert sunflower}} (Geraea canescens), and {{W|evening primerose|evening primroses}} (Oenothera spp.). Across the valleys, Imperial hosts a number of native bush species including the {{W|Larrea tridentata|creosote}} (Larrea tridentata), {{W|Ambrosia dumosa|bur sage}} (Ambrosia dumosa), the {{W|Psorothamnus fremontii|indigo}} (Psorothamnus fremontii), and {{W|Mormon tea}} (Ephedra spp.).

On higher elevations, numerous tree and low-lying shrub species grow along {{W|Bajada (geography)|bajadas}} and {{W|steppe|steppes}}, including the {{W|Prosopis velutina|velvet mesquite}} (Prosopis velutina), the {{W|Parkinsonia florida|palo verde}} (Parkinsonia florida), the {{W|Olneya tesota|desert ironwood}} (Olneya tesota), the {{W|Chilopsis linearis|desert willow}} (Chilopsis linearis ssp. arcuata), {{W|Canotia holacantha|crucifixion thorn}} (Canotia holacantha), and the {{W|Fouquieria splendens|ocotillo}} (Fouquieria splendens).

Fauna
The province contains over a hundred different species and subspecies of native mammals, with the most significant species including the, , , , , , , , , and. Imperial is home to an unknown amount of native bird species including the, the , the , and the. Each winter, thousands of North American bird species feed and rest in Imperial (mostly around the Salton Sea and the Colorado River) during their annual migration towards the Southern Hemisphere. In addition to these groups, Imperial has numerous native species of amphibians and reptiles ( and, , , , ), and hundreds of insects and other species.

Protected areas
In pursuit of preserving, conserving, and protecting ecologically sensitive, both the federal government and Imperial have set aside parts of the province as national parks, provincial parks, or wildlife refuge areas. As of 2017, over 1.5 million acres of land were protected by the government with the intention of protecting the province's environment. While the Royal Parks Service is responsible for maintaining the national parks and wildlife refuge areas within Imperial, the government of Imperial directly administers its provincial parks.

History
Like virtually every other province in Sierra, there was Native Sierran presence in Imperial prior to European exploration and colonization in the 16th century onwards. The and  were the primary native groups who lived along the Colorado River and eastward of it in the mountainous region of the province. Both groups were part of the culture which dominated much of the Sierran Arizona region, as well as Pacífico Norte.

The first recorded time Europeans explored the region was in 1540 when Spanish explorers and  led separate expedition forces across Imperial Valley and the Lower Colorado River region. Recognizing the value and importance of the river, they believed a large settlement could be built along the watercourse's shores. Díaz named the Colorado River as Rio del Tizon ("River of Embers" or "Firebrand River"), based on his observation of the local natives' use of fire to keep themselves warm at night. Both men encountered natives during their short travels, and unlike later "", they treated the natives humanely and respectfully. According to historian Bernard de Voto, in his 1953 Westward the Course of Empire, he wrote: "The Indians had an experience they were never to repeat: they were sorry to see these white men leave."

The province continued to experience increased activity from the Spaniards who utilized the Colorado River to cross the California and Arizona regions. Governor of Spanish New Mexico explored the area during his survey of the Spanish territory in 1776. He crossed the Colorado in Imperial the following year as he returned from his expedition of present-day Northwestern Sierra. On his way towards Mexico City, De Anza used a narrow natural crossing. Despite its ideal location and economic potential, the province saw no significant development until after the Mexican-American War concluded. By then, Mexico had gained independence from Spain, and inherited all of Alta California, including Imperial. However, the growing numbers of Anglo-Americans as well as restless Californios led to California securing its independence from Mexico, bringing Imperial under Californian rule. During the war, Imperial saw military movement, most notably from the, who aided the Anglo-Americans in defeating the Mexican government.

Imperial was formally incorporated into California through the, and was admitted as an integral part of the State of San Diego. During the, the region was used for travel from eastern North America. The popular Yuma Crossing was a major destination along the, and linked the United States and Texas with Southern California. After California reincorporated itself as Sierra, Imperial became part of the Province of Laguna.

With the exception of some development along the eastern side of the Colorado River, Imperial did not receive major demographic growth or significant economic activity until the later end of the 19th century. While the surrounding land seemed barren and uninhabitable, the river was still regarded as highly useful, especially for a nation that was experiencing rapid industrialization and a population boom. The Colorado River Project was commissioned by the government of Sierra in 1888 to begin work along the Colorado River from the Deseret, all the way down to Pacífico Norte. The Colorado River section along present-day Imperial was of particular interest to the government and businesses as it was surrounded by favorable topography (mostly flat and low-lying), and was the closest to major metropolitan regions including the Greater Porciúncula Area and San Diego.

The completion of the and the Colorado River Project turned the desert floor into fertile, arable land. During the project, the formed from a construction accident, becoming Sierra's largest lake. One of the canals, the, became filled with in 1902, and by 1905, heavy rainfall and snowmelt caused the Colorado River to overflow, with some of the excess water running into the. The flood breached a, and ran down two into the ancient seabed of the Salton Sink. With the company failing to fully stop the flooding and the growing sea having no outlet to drain, the sea fully formed. The rapid development in the area transformed the province, and attracted tens of thousands of Sierrans to the region, as well as investors who saw potential in this section of the country.

With active government support, thousands of families were able to settle in the valley and cultivate the land for farming purposes. In the 1920s, a large influx of Mexican-Sierrans from Los Pacíficos moved into the area, as workers or farm owners themselves. During the, the province experienced continued population growth, this time from working-class Anglo-Americans from Texas, Dixie, and the United Commonwealth. Many of these settlers lost their livelihoods to the, a devastating period of severe that ruined local economies. The majority of these immigrants were known as "" as they hailed from the region.

In the 1950s, Imperial experienced a surge in tourism around the Salton Sea. Its ubiquity and location made it a popular tourist destination, and thousands of businesses sprung up in the communities along the lake's shorelines. were one of the largest groups of tourists who visited Imperial, with many coming from Rainier and the United Commonwealth. Snowbirds often bought housing in the area, and would live there during the winter months when the province's weather is warm and pleasant.

The continued urbanization of the Southwest Corridor, and developing suburbs in the Inland Empire displaced tens of thousands of farmers from their livelihoods and homes. Many farmers moved to Imperial where land was still very cheap and plentiful, and had the ideal farming conditions. Although agriculture became the central aspect of the province's economy, real estate and retail boomed in response to the newer communities that formed during the 1980s and 1990s.

Demographics
The Sierra Royal Bureau of Census officially counted a population of 422,978 in Imperial during the 2010 census. On October 16, 2016, the Royal Bureau of Census gave a population estimate of 438,984. This estimate suggested a population increase by 16,006, or a 3.807% increase. This population change included a of 7,256 since the year 2010 (that is 12,033 births minus 4,777 deaths), and a net increase of domestic migration of 6,871 into the province. Immigration from outside the Kingdom of Sierra (mostly from Mexico) resulted in a net increase of 9,385, and domestic migration out of the province resulted in a decrease of 7,506 individuals since the year 2010. According to the 2010 census, of the people residing in Imperial, 48.1% were born in Imperial, 32.1% were born in another Sierran PSA or territory, 1.6% were born abroad to Sierran parent(s), and 18.2% were foreign-born.

There are 117 cities or municipality-level settlements in Imperial. In Imperial, there is no legal difference between cities, towns, and villages, as all are classified as "municipalities". The largest and most populous city in Imperial is (96,928). The smallest city in Imperial is Aztec (178), a census-designated place in Eastern Yuma County.

Racial and ancestral makeup
According to the Sierra Royal Bureau of Census, the 2010 racial makeup of the Province of Imperial was as follows according to self-identification.

Hispanics or Latinos of any race made up 74.2% of the population. Non-Hispanic Whites made up only 13.4% of the population in the 2010 census. In 1980, Non-Hispanic Whites made up 45.7% of the population.

Mexicans are by far the largest ethnic group in the province, and constitute the majority of the province's Hispanic and Latino community. Nearly one-third of Imperial's Mexican population was born in Mexico, and another one-fourth are migrants from the Sierran territories of Pacífico Norte and Pacífico Sur, or New Mexico. The Mexicans form a majority in nearly every municipality in the province, and in all four counties. The first major Mexican-Sierran community existed when the province was still underpopulated, and undeveloped during the late 19th century. Most settlers resided along the eastern bank of the Colorado River, and were descendants of Spaniard and Mestizo colonists from the Spanish and Mexican colonial periods. Today, the highest concentration of Mexican-Sierrans live along the Imperial–Pacífico Norte border, particularly the Calexico–Mexicali metropolitan area, the largest populated area in the province. Other significant Hispanic and Latino groups include recent immigrants from. These mainly include people from and. There are a sizable communities of Germans, Jacobites, Irish, and Englishmen in Imperial, most of which formed from 20th century migration that originated from the Styxie, and ultimately, Eastern North America. During the Great Depression, many farmers from the region moved to Imperial in search of cheaper housing, and less competition. With them, they brought their ubiquitous culture, including the cultural republicanism that is so prevalent within the Styxie. The presence of Styxers in Imperial, and the province's similar economic dependency has led some to call the province the Styxie's southernmost region. In addition, there was a major influx of Anglo-Americans during the. Many displaced farmers from Texas and the Dixie moved to Imperial following the, and were known as "" to locals. Today, descendants of Okies are scattered throughout the province, with some retaining the farming lifestyles of their forebears.

Asian Sierrans have lived in Imperial since the early 20th century after the Sierran Cultural Revolution brought thousands to the province's fertile farmlands. Most Asian migrants were Han and Japanese farm workers, but by the 1950s, immigrants from China, Korea, and Vietnam followed suit. Today, large sections of Asian communities are found in the Salton Sea area, and Calexico. Contemporary era immigration from Asia have mostly been from South Asia and the Middle East. Like Imperial's southern neighbor, Pacífico Norte, there is a traditionally based and growing community of Lebanese and Syrians.

Languages
and are the province's official working languages, although the other seven national languages (,, , , Han, , and Serran) also hold official status, and are usually included in all government documents. The use of Sierran Hanzi is also present in English-language documents, and some instances of Spanish Hanzi. According to the 2010 K.S. Census, 43.2% of the population aged 5 or older speak English at home, one of the lowest percentages among the Kingdom's PSAs. Spanish is the language most commonly spoken at home other than English, and Spanish-speakers constituted 63.2% of the population (including native speakers and second-language learners). Other languages commonly spoken in the province include, , , , Han, Chinese, and Japanese. Virtually all public entities of Imperial's government including public schools provide and support bilingual services in English and Spanish.

There is a noticeable community of speakers (approximately 32,000 speakers), the majority of whom are immigrants from the Sierran territory of the Yucatán and Cancún. The Sierran-Mayan Engagement Institute is based in Imperial. The organization is committed towards preserving, educating, and promoting the language's use in the Sierran mainland.

Religions
According to a 2015 Gallup poll, the religious affiliations of Imperial's population were: 60%, 18% , 5% , 1% , 6% , 7% , and 3% other.

The Ministry of Culture's 2016 Religious and Spiritual Data in Sierra Report indicated that the largest denominations in Imperial were the with 257,431 adherents,  with 23,398 adherents, and the  with 22,777 adherents. Other significant Christian denominations include the, the New Dutch Reformed Church, , , and.

Imperial has the second highest percentage of Catholics in relation to its entire population out of all the Sierran provinces (after Sonora with 72%). Catholicism has been the traditional, prevailing religion in the province. The faith traces its origins to the Spanish colonial period when it was introduced by the Spaniards to the indigenous population. Late 19th-century and early 20th-century immigration from Hispanic and Latin Americans consisted of individuals who were mainly Catholic, further cementing the religion's dominance in the province. This is in direct contrast to the rest of the country, which is predominantly Protestant. Recent immigrants have included Eastern Catholics, mainly Lebanese who immigrated from Los Pacíficos.

Imperial is home to a large community of, the majority of whom live in the Calexico-Mexicali metropolitan area. Most Imperial Muslims are, although , , and adherents of other sects are also represented in the community. The Calexico Islamic Center is one of the country's largest mosques in the Kingdom, and is distinct for its ornamental and vivid architecture.

Culture
Imperial has been home to a relatively new agricultural-based community. Up until recently, Imperial was a sparsely-populated province. Imperial has been strongly influenced by Mexican-Sierran culture, and to a lesser extent, the cultures of the Styxie and Midwestern North America, from the migrant Styxers and Okies. Modern culture in Imperial has some aspects of the Sierran Cultural Revolution, which is most evident in its cuisine. It is one of the top rice-producing regions in the country, and residents heavily incorporate white rice into their dishes. Imperial is home to a vibrant scene for the arts and music, with a strong portfolio of Latin American writers, musicians, poets, and actors. It is the birthplace of the bamba, a dancing combination of the Anglo-American and the Mexican, which is accompanied by a live or prerecorded playing by a  band. In addition, Imperial has been used as the setting for various Hollywood-produced films and television programs, including 1947 drama film Kissed by the Sun and 1980s television sitcom The Oak Keys.

Year-round, Imperial hosts a number of festivals and celebrations. It is famous for the Westmorland Folk Festival, one of the largest folk music events in the world. Both Calexico and Yuma have annual local festivals, including Calexico's La Raza Festival, which celebrates Latin American heritage and cultural diversity.

Sports
The sports scene in Imperial is not well known. As one of the few provinces in the Kingdom without a professional team in any major sport, the province has mainly prided itself with its college sports, most notably in baseball. Prominent college teams in the province include the WIU Rams of the Western Imperial University and the Yuma National Bluejays of the Sierra National University, Yuma. Both universities dominated collegiate baseball during the late 1990s, and were dubbed the "Imperial 90s", with notable players who have gone on to the professional level including Bernheim Deltas pitcher Tommy Hernandez and Palm Springs Pacifiers shortstop Giovanny Madero.

Equestrian sports has been very popular in Imperial. The  style of horseback riding that persists throughout the province traces its origins back to the of the colonial period of Sierra. Annual horse racing tournaments and competitions are held year-round, with the Imperial Sun Derby as one of the country's most premier events of its kind. In addition to horse racing, car racing has also taken hold of the province, most notably -based races. Every summer, off-road racing tournaments are held in the Colorado Desert, attracting hundreds of competitors and thousands of spectators.

Economy
Imperial's economy is the least developed and diversified economy in the Southwest Corridor, and among the lowest in the Kingdom overall. The province remained predominantly agriculturally-based, even during and after, when the rest of the country experienced dramatic industrialization. Its geography, limited resources, and population were major hindrances to the province's development in relation to its neighbors. Imperial's agricultural sector itself did not fully mature until the late 1960s when its population began to increase considerably, and better and more efficient irrigation systems were developed. Major improvements to Imperial's water sources, including the desalination and revitalization of the during the 1980s and 1990s helped boost property values in the province, creating a more attractive market for homeowners. At the turn of the 21st century, as real estate development began in Imperial, new jobs in the province's emerging energy and aviation industries signaled a shift in the province's overall economic portfolio and health. Today, Imperial has established industries in food processing, logistics, commercial and private aircraft, military equipment and technology, machinery, apparel, electricity, transportation equipment, construction equipment, and publishing.

As of June 2017, the Ministry of Finance reported that Imperial had an unemployment rate of 4.4%, putting it slightly above the national average of 4.1%. In the same report, it estimated that Imperial's GDP in 2016 was $47 billion. The Ministry projects an annual GDP growth of 1.8% should current conditions continue.

Agriculture
Despite the rise in the service industry, Imperial's agricultural sector remains as the province's largest economic contributor, especially in the rural areas around the and banks of the Colorado River. Imperial's earliest industries were,  farming, and  (maize) farming, with the former largely limited to the grasslands surrounding the Colorado River. As major improvements to irrigation, infrastructure, and agricultural practices occurred, so did the variety and scale of crop production increase dramatically during the 20th century.

Demand for rice increased during the Sierran Cultural Revolution, and with thousands of Styxie farmers ostensibly refusing to grow these crops, the brunt of early rice production in Sierra was in Imperial. Rice itself was already an established crop in Imperial prior to the province's own incorporation and the Revolution. J. F. Elder, a prominent agribusiness owner, grew high-quality rice, and encouraged farmers to take up rice years before the crop had taken the Kingdom by storm. Although corn and wheat would later become popular crops in the province, neither would overtake the much more water-intensive but profitable rice crops.

Today, Imperial's agricultural outputs is extremely diversified and includes the aforementioned grains,, , , , , , , , , , , , , , (most notably ),  and other forms of  (like ), , and. During the winter, Imperial's agricultural sector accounts for over two-thirds of production consumed in Anglo-America alone. It is the leading producer in, soybean , and vegetable oil in the Kingdom.

Agricultural practices have been carefully regulated and monitored by the government. Imperial is home to one of the Kingdom's most environmentally sensitive and precarious regions, which requires extensive irrigation, water treatment, and reinforced infrastructure to maintain and preserve regional production. Most crops are watered through or  in an effort to limit water use, soil erosion, fertilizer loss, and. In addition, most farms practice, growing between 2 to 5 different crops on the same plot per season. Virtually all agricultural runoff in the Imperial Valley, including displaced salt solutions, flow into the Salton Sea. Numerous methods and practices have been implemented to preserve the sea's water quality to balance between agricultural activity and environmental health. The prevalence of usage has dramatically decreased in the 21st century when the provincial legislature banned several pesticide agents and passed stricter regulation on the use of permitted forms. The Sierran federal government reportedly spent over $10 billion in helping farmers implement alternative practices including and.

Energy
Renewable energy accounts for nearly 30% of the province's energy consumption. The green energy industry is one of the province's fastest growing industries and is projected to experience rapid growth into the 2030s. Imperial has an extensive network of and  powered generators and facilities that help support the high energy-demanding agricultural sector and growing population centers. Practically all around the province receives more than 300 days of sunlight each year. Nearly all areas suitable for green energy are managed by the federal government, which facilities and infrastructure located throughout Imperial Valley, and areas in the Colorado Desert immediately to the north. Land to the east of the Salton Sea is very geologically active and is the site of most of the province's geothermal plants. In addition to these sources, wind and water have also contributed towards energy production. Some sections of land have made considerable use of through large installed  and  derives from the dams along the Colorado River system including the  and the native. However, electricity obtained from wind and hydropower accounted for less than 10% of Imperial's energy budget. The remaining bulwark of energy consumption comes from traditional sources including the burning of and.

Other industries
Industry in Imperial is diverse and is expanding. Among the fastest growing industries in the province is military and. A number of private military contractors including Overstars and Northmann Gunthrop have their bases of operation located in the province. In addition, employment in the Sierran Armed Forces accounts for nearly 10% of the workforce. The KS military installations in the province include Fort Juniper, Rem Air Reserve Base, Elizabeth Army Airfield, Fort Morgiana, Megumin Proving Ground, and Royal Marines Logistics Base Yuma. These installations provide jobs for the enlisted, officers, and civilians, including those in the private industry. A number of Sierra's advanced military technology (mostly aircraft-related) has been developed and tested in Imperial.

The manufacturing sector in Imperial is mostly light-industry and produces a range of products including aircraft equipment, medical devices, construction equipment, electronic components, food products, gas cylinders, home appliances, and automotive parts. These industries are centered around El Centro and represents over half of the city's workforce. Imperial's manufacturing sector is supported by its local logistics industry, which includes a network of several railroads, truck routes, and airfields. El Centro and Yuma are home to major corporations' distribution centers, and are the hubs for transport and logistics in the Sierran South-Central region.

Taxation
Imperial uses with six brackets of provincial income tax ranging from 5% to 20%. The provincial government calculates each household's taxable income after all other taxes including federal have been accounted for and deducted from the pre-tax income in determining the provincial income tax.

Imperial imposes a 4% on all tangible retail sales and goods, with the exception of  [up to $100.00], clothing [up to $50.00], over-the-counter drugs [up to $50.00], certain prescription drugs (no limit), and hygiene products [up to $30.00]. These excluded products are free of sales tax below and up to their maximum tax-exempt amount, after which a reduced income tax of 2.5% is applied. Imperial's is divided into four brackets ranging from 1% to 8%, and a flat  of 11%. Like most PSAs, Imperial itself does not levy property tax. instead, it allows its municipalities to institute their own local property taxes, with owners of real property paying property tax to the county the property is located in. Rates generally range between 0% to 4%.

Government and politics
The province is governed by the Constitution of Imperial, which defines three branches of government: the executive, the legislative, and the judicial. Imperial's is the Queen's viceregal representative, the Lord Superintendent.

The executive branch is led by the, the Governor, who is popularly elected every four years on an even-numbered year. The Governor is supported by the Lieutenant Governor, the Attorney General, the Provincial Comptroller, the Provincial Treasurer, the Provincial Superintendent, and the Provincial Auditor. Unlike most provinces and the federal government, all electable executive offices have a term limit of two terms. The Governor is responsible for leading the executive government, managing and preparing the provincial budget, ensuring that the rule of law is enforced, overseeing the province's various agencies and departments, working with the legislature, and many other functions.
