Roxas, officially the Municipality of Roxas, is a 1st class municipality in the province of Isabela, Philippines. According to the 2015 census, it has a population of 61,773 people.[3]

The municipality is the center of business and commerce in the Mallig Plains Region.


Early settlers were the Kalingas who originated from adjacent places in Mountain Province and some part of Kalinga-Apayao. Despite occasional clashes with Kalingas, Ilocano people settled in this area of the province, and increased their number with an influx from Ilocanos from Central Plains of Luzon and Ilocos Region.

The place used to be called Bindang (Bayani), and was part of the La Provincia del Valle de Cagayan (present day area of Cagayan to Nueva Vizcaya). But in 1839, two new provinces were created by the Spanish conquistadors dividing the La Provincia del Valle de Cagayan into two. One retained the name Cagayan, while a new province of Nueva Vizcaya was created. Bindang was dissolved as Barrio Vira under the municipality of Gamu, Isabela.[5]

In 1938, the area of Mallig Plains was set aside by the National Land Settlement Administration (NLSA) under Settlement No. 2 due to the construction of another National Highway project of President Manuel L. Quezon that passes through the area. But World War II interrupted the implementation of the highway so it remains uncemented for many years. After the war, provincial leaders saw the potential of Barrio Vira as an independent town.

On July 1, 1948 President Elpidio Quirino established Executive Order 136 creating Barrio Vira as an independent municipality named "Roxas" to honor his predecessor Manuel A. Roxas who just died a few months back. It was then inaugurated on July 4, 1948, and Rafael Lintao became its first mayor.

In 1952, the barrios of Holy Friday, San Jose (East), and San Jose (West) were transferred to the newly created town of Mallig.[6] In 1957, the barrios of Callang, Eden, Babanuang, Cabaritan, Sta. Cruz, Malalinta, Mararigue, Calaocan, and Caraniogan were separated to form the municipality of Callang, now San Manuel.[7] In the same year, the barrio of Basilio was renamed to San Jose.[8]


The municipality of Roxas is one of the 34 municipalities comprising the wide province of Isabela. It is exactly located on the central-western part of the province, bounded in the north by the municipality of Mallig, on the north-east by the municipality of Quirino, on the east by the municipality of Burgos, on the south by the municipality of San Manuel all within the province of Isabela and on the west by the municipality of Paracelis in the province of Mountain Province.

The road traversing the municipality of Roxas is the Maharlika Highway or better known as Cagayan Valley Road, connecting to other towns in Isabela particularly the adjacent towns of Gamu, Quirino, Mallig and San Manuel. The southern tip of Cagayan Valley Road connects the town to Manila, which is 9 to 10 hours travel by land and to other southern provinces like Nueva Ecija, Pangasinan and Bulacan.

Roxas lie on a flat fertile land between the two valleys of Cagayan. It occupies an area of 184.80 square kilometres (71.35 sq mi) or 2.01% of the total land area of Isabela. The town is partly urban, and partly rural. The urban area is expanding rapidly throughout the years making it a future city. The rural part of the town compose mainly of rice fields.


The landscape of Roxas is relatively compose of flatlands with minimal rise at certain point with base mountain elevations on the eastern part, on the parts of Sinamar, Simimbaan and San Placido. It is approximately 90% of the land area comprising the town can be described as low-lying hills with rolling terrain and an elevation of 200 feet or 61 meters above sea level.[9] The town is dissected by creeks, river and waterways acting as natural drainage from waters coming from the uplands. The Siffu River, a connection from Ilog ng Cagayan(Cagayan River) traverse west ward from its diversion from Paracelis to Tuguegarao City supplying the rice fields with irrigation.

The center of the town is relatively low relief of flatlands, while the south-western and north-western part having moderately sloping areas comprising the foothills of Mountain Province.

The existence of the National Irrigation Administration (NIA) System in the municipality that provides water supply services in irrigating farmlands makes the locality a prime agricultural community. The presence of these services makes the agricultural workers the highest in number. The agricultural productivity of Roxas is high, reaching as much as 95 percent cultivation rates in rice and corn. Surplus production of rice and corn are being exported to other places. Other crops are vegetables, tobacco and root crops in which production is just sufficient for local consumption. Likewise, the production of meat including pork and poultry is just sufficient but the supply of fish of other kinds aside from the harvest of inland fishpond owners within the locality is dependent on the arrival of supply coming from other places.

Rice field in Baranggay San Rafael, depicts the municipalities agricultural abundance.

In the area, rice is the predominant crop, planted twice a year. The livelihood opportunity is very limited thus,a year-round planting of vegetables is practiced to sustain additional income for the settlers. Farm labor is highly utilized and low productivity was experienced because of manual farming. As such, during peak of drying, farmers are compelled to sell their produce freshly threshed which commands lower price. In 2009, the government provided P3 million financial assistance for the Mestizo 1 hybrid seeds planting and for the establishment of needed agricultural components for Farming improvements. With the Local Government Unit’s strong support, cooperative members embarked on hybrid rice production starting as early as 2007-2008 wet season cropping and followed through the next dry season using 40-percent organic fertilizer.

Roxas municipality prides itself as the "pioneer" in hybrid rice production in the province of Isabela with the farmers now producing their own M1 hybrid seeds. The farmers who belong to three irrigators associations in barangays Simimbaan, Casilbagan and Tanap Progreso, have organized themselves into a cooperative called Simca Model Cluster MPC under the auspices of the Department of Agriculture. The rice cluster operation is an extension strategy in reaching farmers and extending assistance to achieve increased productivity, food sufficiency and job generation. This is initiated in support to the Ginintuang Masaganang Ani (GMA) Rice Program of then President Gloria Macapagal-Arroyo.

Aside from hybrid rice enterprise, they also venture on fishery. Through the Bureau of Fishery and Aquatic Resources (BFAR), the cluster coop had dispersed fingerlings to initial 23 fishery cooperators who have backyard fishpond and rice-fish integrated farming.
