 BASIC FACTS AND ECOLOGICAL PROFILE OF THE CITY OF NAGA

 

Location and Political Territory

 

Located in the southeastern part of the Province of Cebu with a longitude of 123 45’ 30” and latitude of 10 12’ 41” on the Philippine map, the City of Naga is part of Metro Cebu located approximately 21 kilometers away from Cebu City. It takes between 30 and 45 minutes to travel back and forth to the city center from Cebu City. It has a total land area of 10,217 hectares bounded from the north by Minglanilla, from the south by San Fernando, from the east by the Bohol Strait, and from the west by Toledo City. The City has twenty-eight (28) barangays, eleven (11) of which are considered urban located along the coastal areas, namely: South Poblacion, North Poblacion, East Poblacion, West Poblacion, Central Poblacion, Inayagan, Colon, Tina-an, Inoburan, Tuyan, and Langtad while the remaining seventeen (17) barangays are considered rural located in the mountainous areas namely: Tangke, Na-alad, Mainit, Jaguimit, Patag, Cantao-an, Cogon, Uling, Balirong, Cabungahan, Bairan, Pangdan, Alpaco, Lutac, Tagjaguimit, Lanas, and Mayana.

Brief History

The place now known as Naga was abundant with Narra trees in the olden times. The early settlers called the area “Narra,” which was later on coined as “Naga.” Considered as one of the oldest settlements in the Province of Cebu, Naga became a municipality on June 12, 1829 and has gone through a series of reclassification simultaneous with its healthy and dynamic economic development.

 

The tranquil farming and fishing villages of the natives were raised to a fuss when the Spaniards arrived and explored the coal mining in the upland barangays. Coal then became the first export of the town, as the Spaniards mined and sent them to Spain. Second to coal was the cement product as the town was abundant with lime.

 

The mining industry for construction purposes undeniably triggered the successful industrial development of Naga. As the years progressed, quite a number of manufacturing companies and other industries flourished in the place eventually making Naga as one of the industrialized locality in Cebu at present and earned the name “The Industrial Hub of Southern Cebu.”

 

Naga has gained its new status from 1st class municipality into a component city in the First District of Cebu by virtue of Republic Act 9491, which was ratified by a plebiscite on September 02, 2007 under the sponsorship of Congressman Eduardo R. Gullas, now respected as the “Father of the City of Naga, Cebu.” The City of Naga celebrates its charter day every 5th of September.

 

Geophysical Characteristics

 

Geology

 

Alluvium, Carcar limestone formation, Pandan formation, Ilag formation, Toledo-Bulacao andesite, and Uling formation are types of geologic rocks present in the City of Naga. Alluvium can be found in the coastal and river flood plains. Silt, clay, sand, and gravel are found in coastal plains. Narrow alluvium borders most of the interior streams including beach deposits of sand, coral reefs, and some detritus igneous rocks.

The Carcar limestone formation is typically a porous, coralline poorly bedded or massive limestone. This limestone has an average thickness of about 300 meters and is seldom less than 150 meters thick. Because of its great porosity and favorable position in the geologic column, the Carcar formation is noted for its vigorous freshwater springs, which provide excellent water supply for numerous communities.

The Pandan formation flanks the central highlands on the west and concentrate on the east side of the Balamban fault. This formation is made up of cretaceous sediments and metamorphosed limestone. The Ilag Limestone formation generally exhibits a modified haycock topography with vertical cliffs marking its margins. This formation is said to be coal-bearing.

The Toledo Formation is found in low rolling hills and gentle shales broad V-shaped valleys. This formation is composed of white bentoniticshales underlain by brown carbonaceous shales locally coal bearing all with limestone. The Bulacao andesite is folded and faulted with a monoclinal component of a once extensive dome. It is typically perphyritic and generally breciated in texture. Andesite plagivelase, brown or brownish green horablends, augits and hypersthenes constitute the pheneorysts, which are set in glassy microliticgroundness. Zoned plagioclase crystals usually contain abundant vacueles and brown inclusion. The horablends have small extension angles and seem to approach the basaltic type of horablend in optical properties. The Uling Limestone formation occurs mainly as widely scattered ventricular bodies along the principal fault zones of Central Cebu.

 

Hydrology

 

The City of Naga site consists of mountain ranges on the western side while on the opposite eastern side is the Bohol Strait. The mountain ranges have an elevation of around 120 meters above mean sea level (AMSL) and define the watershed. Runoff water flows down from the mountain bringing loose soils and gravel materials from the mountain areas, and via existing gullies, discharges into the coastal areas.

 

Soil

 

Soil composition in the area is of five types, namely: Faraon Clay, Lugo Clay, Faraon Clay Steep Phase, Mandaue Clay Loam and Baguio Clay Loam. Predominant is Faraon Clay Steep Phase, which comprises 39.36% of the total land area.

 

Faraon Clay – This type of soil is usually found in areas with undulating to hilly slope. The principal distinguishing characteristics of this type is its black heavy clay soils with outcrops of gray, coralline and porous limestone. The surface is littered with pebbles and cobbles of limestone. This soil remains moderately friable and maintains its excellent good structure when dry. Those areas with this type of soil are widely planted with coconut, corn, cassava, banana, and fruit trees.

 

Faraon Clay Steep Phase – Areas having this type of soil are located mostly in steep hills and mountains.

 

Lugo Clay – This type is a residual soil developed from lime and shale suited to the growing of sugarcane, coconut, tobacco, banana, etc.

 

Mandaue Clay – The surface soil of this type is light brown to dark depending upon the amount of organic matter and moisture content. It is friable when just moist, thick, sticky and soft when wet and hard when dry. The substratum is made up of compact clay loam.

Climate and Rainfall

 

Temperature is relatively constant throughout the year with daily fluctuation of 7°C. The easterly trade winds bring warm dry air. The weather is relatively moderate and is endowed with a tropical climate. Humidity is 78%, coldest temperature usually occurs during the months of December to February, and wet seasons are expected during November. Mean temperature range is from 19.2°C-36.4°C.

The climate of the City of Naga is characterized by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) as the third type of climate, which is characterized by no distinct wet and dry season. This is predominant throughout the whole province of Cebu. The summer heat, which generally comes in March, reaches its peak in April and May.
