The Land, The Culture, The People, Duero is the Land of vegetables and spices. It is located on the southeastern coast of the province. How it got its name is from the former name Doguero meaning harded. According to the stories handed down through generations, the building of the church caused so much trouble with the curate favoring the erection of the church in Langkis with which another group insisted to have the church in barrio Mawi. The Spanish Priest got mad and called the people Doguero.

HISTORY
Duero lies in the southeastern part of Bohol. It is said in order to settle the matter once and for all, the church was finally constructed right in the boundary of the two contesting barangay, Langkis and Mawi. The place is now the present commercial and residential center of the town. It was established as a regular municipality in 1862. In 1879 it had a population of 5,352. The oldest buildings in the town are the church and the convent. The former was built in 1868. The elementary school building was constructed in 1910.
The name “Doguero” was then the name of the place for quite a long time. However, as years rolled by the infix, “og” from Doguero was lost. Its omission might have been the result of the cross – cultural changes. The name Duero was then use by both transients and the people of the place.
During the Spanish regime, Christianity was introduced in 1860. The priest was the power behind the government, so that conversion of the people was relatively easy.
Today, Duero is among the many bustling town east of the province of Bohol. It had stood the test of time and today the seed; the sturdy branches and the life giving leaves of the vision of its early forefather have borne fruits.
The municipality of Duero is located at the Southeastern part of Bohol province. The municipality of Pilar, on the south bound it on the north by the Mindanao Sea, on the east by the municipality of f Guindulaman, on the west by the municipality of Jagna, and the municipality of Sierra – Bullones on the North West.
Duero is 73 kilometer from the City of Tagbilaran, which is the Capital of the Province. It is accessible via an all – weather road from the City.

PHYSIOGRAPHY
Duero has a total municipality land area of 5889.6966 hectare or 58.89 sq. kilometers based on the Cadastral Survey conducted in 1986. It is composed of twenty-one (21) barangays from which nine (9) are coastal and twelve (12) are located inland.
The northern half of the municipality of Duero has a hilly to mountainous terrain with 18% - 50% over slope, represented by a moderately steep to very steep with elevation ranging from 285 –720 meters above mean sea level, while the Southern half is characterized by level to rolling terrain with 0 – 18% slope and an elevation ranging from 45-m.amsl near the coast to 300m.amsl. further inland.
In the municipality of Duero a total of 607.4 land area is susceptible to extreme/high erosion.
RAINFALL
As of 1997, rainfall data from the Department of Environment and Natural Resources (DENR) showed that Duero has a total rainfall of 26,995 millimeters an average rainfall of 449.92 millimeters. The heavy rainfall occur during the month of July (4,450 ml), September (3,710 ml) and December (3,190 ml).
HYDROGEOLOGY
Hydrogeological interpretation is based on the inventory of well records from Bohol collected during water sources survey in 1998 and information on geological formations from geologic maps and related literature.
Quaternary alluvium covers 5.89 sq km (9.06% of the municipal area), Sierra Bullones Limestone covers 18.11 sq km (27.84% of the municipal area), Carmen Formation covers 16.39 sq km (25.21% of the municipal area), Boctol Serpentinite covers 22.62 sq km (34.79% of the municipal area) and Pillow Basalt covers 2.01 sq km or 3.09% of the municipal area.
Quaternary Alluvium consists of mud, silt, sand, gravel and coral, and shell deposits along low coastal lands and swampy areas, beaches, small flood and river bed deposits. Aquifers with development potential are formed in this formation, wherever there are permeable layers of sand, gravel, coral sand shell deposits. This is confirmed by 162 (160 shallow, 1 open dug and 1 deep) wells drilled in this formation and 4 springs . However, proximity to the coast reduces development potential due to risk of salinewater intrusion
Sierra Bullones Limestone, is a massive, cavernous fossiliferous limestone unit. This formation could be a potential source for water supply. There are 7 wells and 40 springs located in this formation.
Carmen Formation is composed of extensive layers of shale, sandstone, siltstone and marl of low permeability. Shallow aquifer is formed in this formation, as indicated by numerous shallow wells drilled in this formation. However, the formation has a low groundwater potential, due to predominance of shale, siltstone and marl layers of low permeability. There are 149 (135 shallow, 7 free flowing, 5 deep and 2 open dug) wells and 4 springs are located in this formation.
Boctol Serpentinite is ultramatic rock, which are highly sheared, fine to coarse grained and greenish black to bluish green. Semi-schistose to talcose minerals commonly occurs in fractures as fillings. The formation has low permeability and poor groundwater development potential. There are 37 (35 shallow and free flowing) wells are drilled in this formation and 18 springs.
