Milwaukee Mitchell International Airport

Milwaukee Mitchell International Airport is a civil–military airport 5 NM south of downtown Milwaukee, Wisconsin, United States. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023–2027, in which it is categorized as a medium-hub primary commercial service facility. Milwaukee Mitchell International Airport covers 2314 acre and has five asphalt and concrete runways.

The airport is named in honor of United States Army General Billy Mitchell, who was raised in Milwaukee and is often regarded as the father of the United States Air Force. Along with being the primary airport for Milwaukee, Mitchell International is also used by travelers throughout Southern and Eastern Wisconsin and Northern Illinois. Since March 1941, the airport's weather station has been used as the official point for Milwaukee weather observations and records by the National Weather Service, whose area office is located in Sullivan.

History
The original airfield was established in 1920 as Hamilton Airport by local business owner and aviator, Thomas F. Hamilton. Milwaukee County purchased the land on October 19, 1926, and renamed the airport Milwaukee County Airport. The first airport terminal there, the Hirschbuehl Farmhouse, opened in July 1927. That month, Northwest Airlines, Inc., began air service from Milwaukee to Chicago and Minneapolis/St. Paul. In August 1927, world-renowned aviator Charles Lindbergh visited the Milwaukee airport. Kohler Aviation Corporation began providing passenger service across Lake Michigan on August 31, 1929.

During the late depression years (1938–July 1940), a new two-story passenger terminal building was constructed by the Works Progress Administration. On March 17, 1941, the airport was renamed General Mitchell Field after Milwaukee native and air power advocate Brigadier General William "Billy" Mitchell. On January 4, 1945, Mitchell Field was leased to the War Department for use as a World War II prisoner-of-war camp. Over 3,000 prisoners and 250 enlisted men stayed at the work camp. Escaped German prisoners were often surprised to find a large German American population just beyond the fence. The present terminal opened on July 20, 1955, and was designed by Leigh Fisher and Associates. It was renovated and expanded in 1985, designed by Miller, Meier, Kenyon, Cooper Architects and Planners Inc. The "hammerhead" section of the D concourse was added in 1990.

On June 19, 1986, the Milwaukee County Board of Supervisors renamed the airport General Mitchell International Airport. The airport was formerly a hub for AirTran Airways, Frontier Airlines, Midwest Airlines and North Central Airlines. The airport is owned and operated by Milwaukee County, but some Milwaukee business leaders and politicians have advocated privatization or leasing it to a third party for financial reasons.

In February 2019, the airport was renamed from "General Mitchell International Airport" to "Milwaukee Mitchell International Airport," a rebranding meant to highlight the airport's location;   the old name is still used by the FAA and US government.

In March 2023, the airport was recognized by the Airports Council International as one of the best airports in the world, marking the second consecutive year the airport received this recognition. It was one of only 10 airports of any size in the U.S. to earn a 2022 ASQ "Best Airport" award.

Expansion
Mitchell International expanded the runway safety area at the end of the runways after an accident on January 21, 2007, when Northwest Airlines Flight 1726 skidded off the runway following an aborted takeoff. According to the FAA, most airports are encouraged to have a runway safety area no shorter than 1000 ft, though many airports do not. Construction of the runway safety areas began at the end of summer 2009 and was completed in fall 2012.

There was also a "Master Plan" idea to increase the terminal area by stretching the existing terminal (in some cases, to almost double the size) or begin construction of a separate terminal. Nearly all cases would involve major reconstruction on the airport itself, and would have a huge impact on the airport's traffic. These plans were, however, drafted before Mitchell saw a significant reduction in carriers and flights. More recently, in 2012, there were discussions of closing one concourse as a cost-cutting move.

The approved 2018 Milwaukee County Budget contained initial funding for replacement of the now-closed Concourse E with a new International Terminal. It would replace the current International Arrivals Terminal (IAT) which has limited capacity and is not connected to the main terminal building. The new terminal was planned to open in 2020 after the demolition of Concourse E was completed. During October 2018, airport and Milwaukee County officials set a timeline for design, construction and completion of the new International terminal. Pre-design work and bidding concluded in November 2018, with construction set to begin in early 2021 and likely concluding in mid-2022. In May 2020, Milwaukee County announced with the COVID-19 pandemic severely reducing the airport's operations and de facto ending international service temporarily, that the start of the project had been postponed. , no firm start date for the work has been determined, though airport officials are hopeful that work will begin in 2024.

Terminal
Milwaukee Mitchell International Airport has one terminal with two concourses and 38 gates. All international arrivals lacking border pre-clearance must pass through the International Arrivals Building. Concourse C houses Southwest Airlines and United Airlines; and Concourse D houses the remaining airlines at the airport. There is also a Delta Sky Club in Concourse D.

The terminal houses the Mitchell Gallery of Flight (a non-profit museum) and a USO room on the concession level, along with the usual retail outlets, including a small food court and a branch of Renaissance Books which is believed to be the world's first used book store in an airport. There are play areas for children throughout the facility. An observation lot along the northern edge of the airport is open to the public and tower communications are rebroadcast using a low-power FM transmitter for visitors to tune in on their car radios. There is also a new lot on 6th Street, with a Wisconsin historical marker giving the airport's history. Inside the security perimeter is a large clay "peace mural" from Leningrad, now Saint Petersburg in Russia. Created by Soviet citizens, it was exchanged for an equivalent clay mural made by Americans. The Milwaukee mural was covered up during the 2022 Russian invasion of Ukraine.

In April 2017, all airlines housed in Concourse E began moving to Concourse C. This would allow the airport to remodel the concourse and move International Arrivals processing into the terminal. Following redevelopment of Concourse E, the current International Arrivals Building just north of the main terminals will close. Airport officials are hoping to begin work in 2024, with the redeveloped concourse designed to have between 2-5 gates per the airport's Implementation Plan.

US military
The airport also hosts the General Mitchell Air National Guard Base on the eastern area of the airport property, home to the 128th Air Refueling Wing (128 ARW), an Air Mobility Command (AMC)-gained unit of the Wisconsin Air National Guard flying the KC-135R Stratotanker. The wing performs both Federal and State missions and consists of approximately 1000 Air National Guard personnel, both full-time Active Guard and Reserve (AGR) and Air Reserve Technicians (ART), as well as traditional part-time guardsmen, available for worldwide deployment in support of Air Mobility Command and combatant commander tasking. The wing also maintains a KC-135 flight simulator, providing training proficiency for its own crews, as well as other KC-135 flight crews in other air refueling wings and air mobility wings in the Regular U.S. Air Force, the Air Force Reserve Command and the Air National Guard.

Prior to 2007, a second military installation on the southwestern portion of the airport property was known as "General Mitchell Air Reserve Station" and was home to the 440th Airlift Wing (440 AW), an Air Mobility Command (AMC)-gained unit of the Air Force Reserve Command (AFRC) flying the C-130H Hercules. While based at General Mitchell ARS, the 440 AW numbered in excess of 1500 full-time AGR, ART and part-time traditional reservists. Pursuant to 2005 Base Realignment and Closure Commission (BRAC) action, the 440 AW relocated to Pope AFB, North Carolina, in 2007 and the former AFRC facilities were turned over to the Air National Guard, resulting in the installation's renaming.

Accidents and incidents

 * On December 17, 1954, a Miller Brewing Company plane, a converted twin-engine Lockheed Ventura bound for Winnipeg on a Friday evening, had trouble with both engines and crashed shortly after takeoff from Mitchell Field. All four on board were killed, which included company president Fred Miller and his oldest son, 20-year-old Fred Jr., and the two company pilots, brothers Joseph and Paul Laird.
 * On August 4, 1968, a Convair CV-580, flying as North Central Airlines Flight 261, collided in mid-air with a rented Cessna 150F 11.5 mi southwest of the airport. The Cessna was destroyed, but its cabin remained embedded in the Convair's forward baggage compartment; the Cessna's three occupants were killed. The Convair made a safe emergency landing at Milwaukee. The Cessna was on a VFR flight from Lombard, Illinois to Sheboygan County Memorial Airport in Sheboygan Falls. It was determined that the inability of the Convair 580 flight crew to detect the Cessna 150 visually in sufficient time to take evasive action, despite having been provided with three radar traffic advisories, caused the crash. Visual detection capabilities were reduced by the heavy accumulation of insect smears on the windows of the Convair. Visibility was further reduced by haze, smoke and sunglare, and by the inconspicuous colour and lack of relative motion of the Cessna.
 * On January 29, 1969, a, operated by the , crashed just short of the runway on . The weather was foggy with a visibility of a half mile. Four of the 11 people on board were killed and the plane was damaged beyond repair.
 * On January 22, 1971, Northwest Airlines Flight 433 was hijacked after taking off from Milwaukee to Detroit, Michigan. The hijacker demanded to be taken to Algeria, but landed in Cuba.
 * On July 27, 1974, a USMC Hawker Siddeley AV-8A Harrier crashed during a hover maneuver at as part of an air show demonstration flight. The impact of the crash initiated the firing of the pilot's ejection seat and the pilot survived.
 * On September 6, 1985, Midwest Express Flight 105, Midwest's first and only fatal accident, crashed upon takeoff from Milwaukee. One of the airline's Douglas DC-9s crashed while taking off, bound for Atlanta's Hartsfield International Airport. According to NTSB reports, the crash was caused by improper pilot reaction when the plane's right engine failed due to stress corrosion cracking. The improper flight control inputs caused an uncommanded roll and accelerated stall. The 31 people on board died.
 * On December 10, 1993, a Wisconsin Air National Guard KC-135 blew up on the ground. Six maintenance personnel died.
 * In early August 1997, an SR-71 declared an in-air emergency prior to a fly-by at the Oshkosh Airshow and diverted to General Mitchell International Airport. No one was hurt in the incident.
 * On August 31, 2005, a Midwest Airlines Boeing 717 bumped a weed spraying truck and damaged the plane's left wing. No one was hurt in the incident.
 * On January 21, 2007, a Northwest Airlines DC-9, Northwest Airlines Flight 1726 skidded 400 ft off the end of a snowy runway at Milwaukee International Airport. The accident was due to an explosion in one of the engines, forcing the pilot to abort takeoff. The aircraft was headed for Detroit Metropolitan Wayne County Airport and was to continue on to Buffalo Niagara International Airport. Amongst the 104 people aboard, only one back injury was reported.
 * On January 23, 2007, two Freight Runners Express cargo planes collided and burned on a taxiway. Both pilots were able to escape without injury. The planes were a Cessna 402 and a Beech 99. An NTSB investigation determined both pilots and air traffic control were at fault for the accident.
 * On June 4, 2007, a Cessna Citation II crashed after reporting a runaway trim tab. The pilot issued a distress signal within five minutes after taking off. The plane then crashed into Lake Michigan two miles (3 km) off shore. The plane was carrying an organ transplant team from the University of Michigan back to Willow Run Airport. There was a crew of two and four passengers aboard. All six died.
 * On September 12, 2008, at 7:13 PM, a Cirrus SR22 heading from Milwaukee bound for Lakeland Airport in Vilas County crashed half of a mile southwest of the airport. All three people on board died.

Isabela (province)

Isabela, officially the Province of Isabela (Probinsia ti Isabela; Provinsia na Isabela; Lalawigan ng Isabela), is the second largest province in the Philippines in land area located in the Cagayan Valley. Its capital and the largest local government unit is the city of Ilagan. It is bordered by the provinces of Cagayan to the north, Kalinga to the northwest, Mountain Province to the central-west, Ifugao and Nueva Vizcaya to the southwest, Quirino, Aurora and the independent city of Santiago to the south, and the Philippine Sea to the east.

This primarily agricultural province is the rice and corn granary of Luzon due to its plain and rolling terrain. In 2012, the province was declared as the country's top producer of corn with 1,209,524 metric tons. Isabela was also declared the second-largest rice producer in the Philippines and the Queen Province of the North.

Isabela is the 9th richest province in the Philippines as of 2021. The province has four trade centers in the cities of Ilagan, Cauayan, Santiago and the municipality of Roxas. Santiago City is considered to have the fastest-growing local economy in the entire Philippines.

Etymology
The province was named after Isabella II, who was queen regnant of Spain from September 29, 1833, until September 30, 1868, when she was deposed in the Glorious Revolution, and her formal abdication two years later.

There have been proposals to change the name to something more indigenous, but these were rejected by the people of Isabela.

History
The province of Isabela used to be a vast rainforest where numerous indigenous ethnolinguistic groups lived. Many of the same ethnic groups still live in the province. Shell midden sites and other archaeological sites throughout the province constitute the material culture of those groups during the classical era.

Spanish colonial period
During the Spanish era, prior to 1856, the Cagayan Valley was divided into only two provinces: Cagayan and Nueva Vizcaya. The Province of Cagayan at that time consisted of all towns from Tumauini to Aparri in the north. All other towns from Ilagan southward to Aritao composed the Province of the old Nueva Vizcaya. In order to facilitate the work of the Catholic missionaries in the evangelization of the Cagayan Valley, a royal decree was issued on May 1, 1856, creating the Province of Isabela consisting of the towns of Gamu, Old Angadanan (now Alicia), Bindang (now Roxas) and Camarag (now Echague), Carig (now Santiago City) and Palanan, all detached from the Province of Nueva Vizcaya; while Cabagan and Tumauini were taken from the Province of Cagayan. The exception is Palanan, which was established in 1625 by Spanish forces who arrived by ship from the Pacific coastal town of Baler in Tayabas province (now part of Aurora). Thus, Palanan was originally a part of Pampanga, then to Laguna, Tayabas (now Quezon Province; Tayabas became independent from Laguna), and Nueva Ecija, before being transferred to Nueva Vizcaya and finally Isabela. Also, unlike the rest of Cagayan Valley, it was served by Franciscan missionaries from Baler rather than the Dominicans. The population of the town was natively Paranan, then subsequently augmented by local Negritos, migrants from Baler who are Tagalogs and outlaws from Cagayan Valley, with the lingua franca of the settlement being Tagalog as opposed to Ilocano or Ibanag.

The province was placed under the jurisdiction of a governor (Lieutenant Colonel of Cavalry Francisco Contreras y Urtasun) with Ilagan as the capital, where it remains up to present. It was initially called Isabela de Luzón to differentiate from other places in the Philippines bearing the name of Isabela. The new province was named after Queen Isabella II of Spain. During that time, the Spanish controlled only the areas along the Cagayan River, leaving the Mallig Plants, the Magat River and the Sierra Madre Mountains to Gaddang tribes.

The Atta or Negritos were the first people in valley. They were later moved to the uplands or variably assimilated by the Austronesians, from whom the Ibanags, Itawes, Yogads, Gaddangs, Irayas, Malawegs, and Paranans descended - who actually came from one ethnicity. These are the people found by the Spaniards in the different villages along the rivers all over Cagayan Valley, including present Isabela. The Spaniards rightly judged that these various villagers came from a single racial stock and decided to make the Ibanag language the lingua franca, both civilly and ecclesiastically for the entire people of Cagayan which they called collectively as the Cagayanes which later was transliterated to become Cagayanos.

Various other peoples, mainly the Ilocanos, Pangasinenses, Kapampangans and Tagalogs, as well as Visayans, Moros and even foreigners like the Chinese, Indians, Arabs, Spaniards and others were further infused to the native Cagayanes to become the modern Cagayano, and Isabeliño in the exact province, that we know today.

American invasion era
Although the province did not play a major role in the revolt against Spain, it is in Palanan that the final pages of the Philippine Revolution were written when United States troops, led by General Frederick Funston, finally captured General Emilio Aguinaldo on March 23, 1901. To commemorate this historical event, in 1962 the town officials constructed a monument by the Palanan City Hall, right on the spot where General Aguinaldo was captured, to memorialize the historic event. The monument was inaugurated on June 12, 1962, Philippine Independence Day, and still stands.

Isabela was re-organized as a province under the American military government through Act No. 210, passed August 24, 1901.

The Americans built schools and other buildings and instituted changes in the overall political system. However, the province's economy remained predominantly agricultural, with rice replacing corn and tobacco as the principal crop.

Japanese occupation era
World War II stagnated the province's economic growth but it recovered dramatically after the war. In 1942, Imperial Japanese forces occupied Isabela. In 1945, the liberation of Isabela commenced with the arrival of the Philippine Commonwealth troops under the 11th Infantry Regiment, Philippine Army, USAFIP-NL and the recognized guerrillas attacked by the Japanese Imperial forces in World War II.

A new wave of immigration began in the late 19th and 20th centuries with the arrival of the Ilokano who came in large numbers. They now constitute the largest group in the province, and it was only in this large-scale Ilocano immigration & settlement that made Ilocano language replaced Ibanag as the lingua franca of the province. Other ethnic groups followed that made Isabela the "Melting Pot of the Northern Philippines".

Postwar era
In the years after the Second World War, Isabela was ruled by the Dy family for 35 years (1969-2004). The dynasty was started by the patriarch of the family, Faustino N. Dy Sr., who served as the mayor of Cauayan from 1965 to 1969 and sat as provincial governor for 22 years (1969–1992), surviving the initial attempts of President Ferdinand Marcos to remove him for being a member of the political opposition during the imposition of Martial Law in 1972 and winning reelection in 1988 after his removal by President Corazon Aquino after he had sided with Marcos in 1986.

During the Marcos dictatorship
By the first term of the first term of the presidency of Ferdinand Marcos, Isabela had become known among students activists for its remoteness and the poverty of its agricultural workers, making it a favorite destination for "dissatisfied, alienated young activists." So when the Communist Party of the Philippines (CPP) was established in 1968 after splitting from the largely-defeated old Communist Party (Partido Komunista ng Pilipinas-1930), Isabela became one of the first strongholds of its armed wing, the New People's Army. The actual size of the NPA at the time was very small, reportedly with only 60 guerrillas and 35 WWII-era guns as of 1969. But Marcos hyped up its formation, supposedly because this would help build up political and monetary support from the US. The Armed Forces had a number of initial successes against the NPA in Isabela at this time, including the discovery of the Taringsing Documents in Cordon outlining plans for a communist takeover; and the failed landing of arms bound for the NPA in Palanan during the MV Karagatan incident in 1972. These incidents were cited as some of the justifications for the declaration of Martial Law by Marcos later that year.

With only a year left in his last constitutionally allowed term as president Ferdinand Marcos placed the Philippines under Martial Law in September 1972 and thus retained the position for fourteen more years. This period in Philippine history is remembered for the Marcos administration's record of human rights abuses, particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship. Two of the major detention centers for political detainees located in Isabela were Camp Melchor F. dela Cruz in Barangay Upi in Gamu, in which officers of the Armed Forces Northern Luzon Command were also stationed; and the Headquarters of the Isabela Province Philippine Constabulary in Barangay Baligatan, Ilagan. renamed Camp Lt. Rosauro Toda Jr. in 2020.

The province of Isabela became a particular center of both conflict and protest when Marcos cronies Danding Cojuangco and Antonio Carag managed to block a Spanish-era grant which was supposed to see the return of Hacienda San Antonio and Hacienda Santa Isabel in Ilagan to local farmers. Cojuangco and Carag purchased the two haciendas themselves, displacing tens of thousands of farmers who were supposed to get those lands back a hundred years after the Spanish acquired them.

In its desire to serve its parishioners, the Roman Catholic Diocese of Ilagan hosted a Social Action Center which would help the farmers. In the Social Action Center's newsletter, the "Courier," researcher Sabino Padilla Jr. documented and exposed the ways by which Cojuangco, Carag, the provincial government, and the military harassed the farmers who were supposed to get the land. This all led to a protest march in joined by 12,000 protesters from all over Isabela, and eventually, for 4,000 farmers to finally get the titles to their land. But it also earned the ire of the administration.

In 1982, Padilla and 12 others were arrested by the regime and jailed under poor conditions at the Bayombong, Nueva Vizcaya Stockade of the Philippine Constabulary until almost the end of the Marcos regime. In 1983, soldiers went as far as to raid the residence of the Bishop of Ilagan, Miguel Purugganan, in search of alleged rebels and firearms. They found none but continued to keep Bishop Puruggananan and the church workers under him under military surveillance.

It was also during the dictatorship that Marcos began awarding logging concessions to his cronies in the areas of the Sierra Madre region, which heralded the beginning of widescale deforestation and other environmental problems that affect the province since then, despite Marcos creating the Palanan Wilderness Area in 1978 which was later expanded by President Fidel V. Ramos to become the Northern Sierra Madre Natural Park in 1997.

In 1975, construction began on the Magat Dam on the boundary of Ramon, Isabela with neighboring Ifugao Province, becoming a catchbasin for 8 rivers upstream in Ifugao and serving multiple functions, including: irrigating of agricultural lands; flood control; and power generation. The construction was protested by the Ifugao people due to the flooding of their ancestral lands, but the dam was eventually completed in 1982, partially funded through a loan from the World Bank.

After the People Power Revolution in 1986, many of the activists who had joined the underground movement decided to "surface," as the new administration of Corazon Aquino released political prisoners and initiated peace talks. However, anticommunist sentiment in her new cabinet made the peace process difficult, and negotiations eventually collapsed, and the insurgency in Isabela persisted.

Contemporary
Following the 1986 People Power Revolution, known as the current Fifth Philippine Republic, under the 1987 Philippine Constitution, various changes have been attempted since then in the province.

Dy Sr. was succeeded by his son, Benjamin G. Dy, in the gubernatorial seat from 1992 to 2001. Another Dy took over the gubernatorial seat in 2001 when Faustino Dy Jr. won the 2001 elections after having served as the district representative of the 2nd Legislative District of the province from 1992 to 2001. It was only in the 2004 elections that the family's control of the gubernatorial seat ended when Grace Padaca, a former journalist, won over Faustino Dy Jr. She was the first woman to serve as the governor of the province. After serving for six years (2004-2010), Padaca was defeated in the 2010 National Elections by Faustino "Bojie" G. Dy III who served as governor of the province for three consecutive terms (2010-2019). He was then succeeded by Rodolfo "Rodito" Albano III, a member of the Albano dynasty that dominates Isabela's 1st congressional district.

In July 1994, the municipality of Santiago was converted into an independent-component city in the province of Isabela. Several attempts were made to revert the status into a component city but did not go through. Santiago is geographically located in Isabela but not under the administration of the province. Its electorates are prohibited to participate in the provincial-level elections except in the 4th legislative district of Isabela where the city belongs for congress representation.

In 1995, Republic Act 7891 was passed, legislating that Isabela be divided into two new provinces: Isabela del Norte and Isabela del Sur. A referendum was held on the same year with a slight majority voting against partitioning the province.

In 1999, the municipality of Ilagan, also serving as the capital town of the province, sought to become a city. The plebiscite held on March 14, 1999, turned down its first bid for cityhood. The majority of the people voted no in that event. In its second attempt to cityhood, the campaign did not go through due to lack of concurrency in the senate in 2006. Finally, Ilagan became a city, after its third move gained 96% of the votes in a plebiscite conducted on August 11, 2012. The night after the plebiscite, Ilagan was declared as a component city in the province.

In 2001, the municipality of Cauayan became a component city in the province of Isabela.

In 2019, the province was reorganized into six districts, thereby increasing the number of legislative districts from four to six. Cities and municipalities were retained and others were reapportioned to the current district assignments.

2020 Ulysses Flood
Cagayan has been heavily impacted by changing weather pattern changes resulting from climate change, with the 2020 Ulysses flood being counted as one of the most severe examples.

In November 2020, Typhoon Vamco (locally known in the Philippines as Typhoon Ulysses) crossed the country, dams from all around Luzon neared their spilling points, forcing them to release large amounts of water into their impounds including Magat Dam. The dam opened all of its 7 gates at 24 m, releasing over 5,037 cubic metres (1,331,000 US gal) of water into the Cagayan River flooding numerous riverside towns.

Because there was very little media coverage of the flooding in the area in the wake of the COVID-19 lockdown in Luzon and the Shutdown of ABS-CBN broadcasting earlier that year, residents resorted to social media to request the national government for rescue. As a result of the catastrophe, the National Irrigation Administration (NIA) indicated that it would review its protocols regarding the release of water in Magat Dam and improve its watershed.

Geography
Isabela comprises an aggregate land area of 12,414.93 km2, representing almost 40 percent of the regional territory. It is the largest province in the island of Luzon and the second largest province in the Philippines by land area. Occupying the central section of the Cagayan Valley region in Luzon, Isabela is bordered by Cagayan to the north, Kalinga to the northwest, Mountain Province to the central-west, Ifugao and Nueva Vizcaya to the southwest, Quirino to the south, and Aurora to the south. To the east lies the Philippine Sea, making Isabela one of the typhoon-prone provinces in the country.

The province is divided into three physiographic areas. The eastern area, straddled by the Sierra Madre mountain range, is rugged and thickly forested. A substantial portion is uncharted. These unexplored hinterlands are home to a rich variety of flora and fauna, and some are under government reservations. It is home to one of the world's largest remaining low-altitude rainforests, with numerous unknown endemic species of flora and fauna and biological diversity in the protected area known as the Northern Sierra Madre Natural Park. Isabela has 600000 ha of Cagayan Valley’s 900000 ha of forest cover.

The highest point of the province is located near the border with Cagayan. Mount Dos Cuernos peak has an elevation of 1785 m located in San Pablo near the border with Maconacon. Other notable peaks in the Northern Sierra Madre Natural Park is Mount Cresta in Divilacan with an elevation of 1672 m.

The western area is a fertile valley hemmed by the Central Cordillera. It is crisscrossed by the mighty Cagayan River, Siffu River, and Magat River.

Mallig Plains region
Mallig Plains is a region in the western section of the province. Its name was derived from the rolling terrains or kilometers of plain lands in western part of Isabela. The municipality of Roxas serves as the business center of the region. The Plains encompassing the municipalities of Quezon, Mallig, Quirino, Burgos, Aurora, San Manuel and Roxas.

Administrative divisions

Isabela is politically subdivided into thirty-four (34) municipalities, two component cities and one independent component city. The province is represented in the Philippine House of Representatives with six legislative districts.

The province has ten first class municipalities, two second class cities and one first class independent component city. Ilagan City, which became a city thirteen years after its failed cityhood proposal in 1998, it is now Luzon’s largest and the country’s fourth biggest city after Davao City, Puerto Princesa and Zamboanga City by land area.

Provincial capital and component city

Independent component city

Component city

Municipality

Barangays
The 34 municipalities and 3 cities of the province comprise 1,055 barangays, with Rizal in Santiago City as the most populous in 2010, and Catalina in Cauayan as the least. If cities are excluded, Bugallon Proper (Poblacion) in Ramon has the highest population, and Uauang-Tuliao in Santo Tomas has the lowest.

Governors
After Isabela was re-organized as a province under the American regime in 1901, its first provincial governor was Rafael Maramag, a former Municipal President and also the first Municipal President of the capital town Ilagan. He was succeeded by his brother, Gabriel. Since 1969, the position has been occupied mostly by members of the Dy family, a political dynasty based in Cauayan that has expanded to neighboring municipalities. The current governor is Rodolfo "Rodito" Albano III, a member of the Albano dynasty that dominates Isabela's 1st congressional district and is an ally of the Dys.

Legislative districts
On September 27, 2018, Republic Act No. 11080, an act reapportioning the province of Isabela into six legislative districts from four, was signed into law and the reapportioned districts elected its representatives starting in the 2019 midterm elections. Accordingly, the six districts are as follows:

 * First District: Cabagan, Delfin Albano, Divilacan, Ilagan City, Maconacon, San Pablo, Santa Maria, Santo Tomas and Tumauini.
 * Second District: Benito Soliven, Gamu, Naguilian, Palanan, Reina Mercedes and San Mariano.
 * Third District: Alicia, Angadanan, Cabatuan, Ramon and San Mateo.

Agriculture
Agriculture is the biggest industry in Isabela. As the country's top corn producing province, it contributes 13.02% of the annual national yellow corn production. Asia's largest post-harvest corn processing facility, the Mindanao Grains, is located in the town of Reina Mercedes.

As second highest rice-growing province nationwide, Isabela produces 15% of the aggregate national rice production on an annual basis. Being a surplus producer of the Filipinos’ staple crop, the province's rice sufficiency rate is at 224%, which means that Isabelinos produce more than they consume and are in fact responsible for supplying the rice requirements of Metro Manila and many other provinces. The unprecedented increase in palay production of Isabela made the province the Hybrid Rice Champion of the Philippines.

High-value agricultural crops grown in Isabela include monggo, tobacco, coffee, banana, and mango. Its livestock and poultry industries are also on the rise, especially dairy processing, hog production, cattle breeding, and commercial poultry raising.

Farming is highly mechanized as most of the agricultural lands are irrigated. With the presence of the Isabela State University, joint ventures and other foreign assisted projects and the Magat Dam contribute to the high productivity in agriculture. It is also the hub of trade and commerce and other economic activities due to its central location in the region. The wood industry used to be a top earner for the province but due to the logging ban imposed in the Cagayan Valley Region, activities in this industry considerably declined. However, furniture making using narra wood and other indigenous forest materials continue to exist.

Isabela is one of the most progressive provinces of the Philippines having been adjudged as the most outstanding province on food security in the Gawad Sapat Ani Awards 2000. For corn production, Isabela ranks first among the top ten corn producing provinces for cy 2004, contributing 15.70% to national production.

Ilagan City was proclaimed as the Corn Capital of the Philippines for being the top corn producer among the 34 municipalities and 2 cities of the province as well as in the whole country.

Forestland

Forestland covers 54.37% or 579819 ha of Isabela's total land area of which 62% is protected forest and 38% is production forest. The best quality of timber resources in the Philippines are found in Isabela's forests. Isabela's vast forest resources are now being ecologically managed to effect sustainable forest-based resource not only for the wood working industry but to secure a balanced ecosystem. The woodwork industry continues to operate under a regulated system, particularly the making of furniture using indigenous materials.

Fisheries

Isabela has a fertile fishing ground on the Pacific Coast. The Magat Dam reservoir is utilized for fish cage operations for tilapia production for domestic markets. Another thriving industry in the province is aquaculture, sustained by inland fishing through 1,108 hectares of developed freshwater fishponds and 450 hectares of fish cage culture at Magat Dam Reservoir. There are 238 marine fish species that were identified by the Bureau of Fisheries and Aquatic Resources in Isabela's coastal seaboard municipalities of Maconacon, Divilacan, Palanan, and Dinapigue.

Mineral and energy
Large deposits of copper, gold, zinc and chromite, manganese and nickel have been found in Isabela. It also has extensive deposits of non-metallic minerals such as limestone, clay, marbles, guano, sand and gravel, and boulders. Indigenous energy sources such as natural gas and hydroelectric capabilities have been found to be abundant in the valley. Many of its mineral reserves have yet to be fully tapped.

Power

Solar and biomass power plants in the city of Cauayan and in the town of Alicia have started operating in 2015 to supplement the region's high energy demand. The online solar power plant in Cauayan is capable of supplying at least 20 megawatts while the biomass power plant in Alicia can produce another 20 megawatts. Both systems provide clean and renewable energy. The P2 billion power facility established by the Isabela Biomass Energy Corporation (IBEC) was built to augment power supply in the Cagayan Valley region. The use of biomass as fuel makes the power plant carbon neutral and sustainable. This biomass power facility is the first in the region and is designed to provide economical source of energy as well as job opportunities to residents of the host town/city.

On 27 May 2015, the service contract of the largest solar PV power plant in the country has been approved by the Department of Energy (DOE). The P7-billion worth 100 MW Solar PV project in the city of Ilagan is designed to reduce the current shortage of electricity that causes regular blackouts that results to industry closures as well as inconvenience to the consumers. The solar power facility will be constructed at a 100-hectare land at Barangay Cabannungan, several kilometers away from the city proper.

In December 2022, the Department of Energy (DOE) has given the go signal to a Filipino-French joint venture to develop one of the biggest renewable energy projects in the Philippines - an P18-billion solar farm in Ilagan City. The project will be undertaken by San Ignacio Energy Resources Development Corporation, which is part of the Nextnorth Energy Group developing over 450 megawatts of solar and hydro projects in Northern Luzon, and French firm Total Eren S.A. The project will involve the development of a 440 MWp/336 MWac solar PV project to be built on around 400 hectares of available land located along the Northern Luzon high voltage transmission network of the National Grid Corporation of the Philippines (NGCP). The project is scheduled to start construction in 2024 and start feeding electricity into the grid in 2025.

Transportation

Isabela is accessible by all means of transportation. Almost 180-kilometers of the Pan-Philippine Highway pass through the different towns and cities of the province. Several bus companies offer daily trips to different routes like Manila, Dagupan, Baguio, Ilocos, and vice versa. Public utility vans and small-time bus operators ply daily trips from Tuguegarao in Cagayan to Santiago City vice versa, while jeepneys and tricycles are commonly used as the basic mode of transportation within the province's jurisdiction.

Ilagan-Divilacan Road
The construction of an 82-kilometer route across the Sierra Madre National Park is intended to improve access to the province's three coastal communities. The project's authorized budget contract, worth P1.5 billion, will traverse across the foothills of the Northern Sierra Madre mountain ranges, which cover 359,486 hectares. The idea is to rehabilitate an ancient logging route that was utilized until the 1990s by a defunct logging firm. It will begin in Barangay Sindon Bayabo in Ilagan City and end at Barangay Dicatian in Divilacan's seaside town. The project is scheduled to conclude in 2021.

The secluded coastal settlements of Divilacan, Palanan, and Maconacon are frequently accessible only by boat or plane, making them difficult to reach at times of emergencies and calamities. There are no highways connecting Ilagan's capital city to the coastal districts, denying locals access to basic commodities and social services such as health care. Once completed, the route is projected to bolster coastal economies, citing Divilacan's 119-hectare beach and freshwater areas that have attracted tourists. Resolution No. 11 of the Protected Area Management Board (PAMB) reclassifies areas of the Sierra Madre as a special-use zone. Additionally, the Agta and Dumagat communities in the vicinity have signed a memorandum of understanding with the provincial administration expressing their support for the road project. At least 1,800 Agta and Dumagat have made their homes in park areas. However, the road's impact on the protected forest has upset neighbors, who believe the project will harm the region's woods and ecosystems. The project has been delayed in recent years due to worries about the road's possible environmental impact. The Cagayan Valley Regional Development Council required that the road's proponents conduct a comprehensive analysis of the road's impact on the area's biodiversity.

Airports and sea ports
There are three airports in the province. The Cauayan Airport is the primary airport in the province serving a trip to Manila, Palanan, and Maconacon. The other two are the Palanan Airport in Palanan and Maconacon Airport in Maconacon. The country's leading passenger airline Cebu Pacific services the Cauayan-Manila-Cauayan Route. Light planes operated by Cyclone Airways and WCC Aviation's Sky Pasada Have flights from Cauayan Domestic Airport to the community airports in Palanan and Maconacon. The province has two minor seaports, the Divilacan Port and Palanan Port in the coastal towns of Divilacan and Palanan. The trade going to the ports comes primarily from major seaports in Cagayan such as Port of Aparri in Aparri, Cagayan, and Port of San Vicente and Port Irene, both in Santa Ana, Cagayan. The other two airstrips are found in Divilacan, and in Magat River Management Project Site.
