An Ecological Profile (EP) is the more comprehensive replacement of the usual socioeconomic profile, which gives equal coverage to the physical, biological, socioeconomic, cultural and built environments. It consists of three main parts: an Ecosystem Analysis, Sectoral Studies, and Special Area Study focusing on Naga’s built heritage. They are broken down into the following chapters: Chapter 1 presents a brief history of Naga City. Chapter 2 profiles the city’s geophysical environment. Chapter 3 presents the highlights of studies on local climate change adaptation and disaster risk reduction. Chapter 4 takes a closer look at the socio-demographic profile of Naga. Chapter 5 provides an overview of the local economy. Chapter 6 profiles the city’s infrastructure and environmental support systems. Last but not least, Chapter 7 looks at Naga’s heritage resources and its proposed heritage district. BRIEF HISTORY1 Pre-colonial era. Bicol region is closely allied with the confederation called the Kedatuan of Madja-as (Itself formed by Austronesian rebels against Rajah Makatunao in a civil war in Brunei), which is located in Panay island. According to the Maragtas, two Datus who followed Datu Puti eventually arrived at Taal Lake and then split up, one group settling later around Laguna de Bay, and another group pushing southward into the Bicol Peninsula, making Bicolanos an intermediate group between people from Luzon and people from the Visayas. The discovery of an ancient tomb preserved among the Bicolanos refers to some of the same deities and personages mentioned in the Maragtas examined by anthropologists during the 1920s. Spanish colonial period. In 1573, on his second expedition to this region, the conquistador Juan de Salcedo landed in a village and named it "Naga" because of the abundance of Narra trees ("Naga" in Bikol).2 In 1575, Captain Pedro de Chávez, commander of the garrison left behind by Salcedo, founded on the site of the present central business district (across the river from the original Naga) a 1 “Naga, Camarines Sur.” https://en.wikipedia.org/wiki/Naga,_Camarines_Sur 2The late Fr. Raul Bonoan, S.J., former president of Ateneo de Naga University, however advanced an alternative theory linking the name to the Nagas, a serpent-worshipping northern Indian tribe that settled near or around water springs. Spanish city which he named La Ciudad de Cáceres, in honor of Francisco de Sande, the governor-general and a native of the city of Cáceres in Extramadura, Spain. It was still by this name that it was identified in the papal bull of August 14, 1595 that erected the See of Cáceres, together with those of Cebú and Nueva Segovia, and made it the seat of the new bishopric under the Archdiocese of Manila. In time, the Spanish city and the native village merged into one community and became popularly known as Nueva Cáceres, to distinguish it from its namesake in Spain. It had a city government as prescribed by Spanish law, with an ayuntamiento and cabildo of its own. At the beginning of the 17th century, there were only five other ciudades in the Philippines. Nueva Cáceres remained the capital of the Ambos Camarines provinces and later of the Camarines Sur province until the formal creation of the independent chartered city of Naga under the Philippine Republic. The bishops of Cáceres occupied a unique place in the Philippine Catholic hierarchy during most of the Spanish regime. By virtue of the papal bull of Gregory XIII, ecclesiastical cases originating in the Spanish East Indies, which ordinarily were appealable to the Pope, were ordered to be terminated there and no longer elevated to Rome. Decisions of bishops were made appealable to the archbishop and those of the latter to the bishop of the nearest see. Thus, in the Philippines, the decisions of the Archbishop of Manila were subject to review by the Bishop of Cáceres whose jurisdiction then extended from the whole Bicol region, the island- province of Marinduque and the present-day Aurora, which was once part of the former Tayabas Province, which is now the province of Quezon. In this sense, bishops of Bikol were delegates of the Pope and could be considered primates of the Church of the Philippines. This was the reason why bishops of Cáceres and archbishops of Manila were sometimes engaged in interesting controversies in the sensational Naga case and in such issues as canonical visitation and the secularization of the parishes. As papal delegate, Bishop Francisco Gaínza, then concurrent bishop of Cáceres, sat in the special ecclesiastical tribunal which passed upon the civil authorities' petition to divest Fathers Burgos, Gómez, and Zamora of their priestly dignity. Gaínza did not only refuse the petition but also urged their pardon. American colonial period. With the advent of the American rule, the city was reduced to a municipality. In 1919, it lost its Spanish name and became officially known as Naga. It acquired its present city charter in 1948, and its city government was inaugurated on December 15 of the same year by virtue of Republic Act No. 305. Rep. Juan Q. Miranda sponsored this legislative act which put flesh into the city's bid to become among the only few independent component cities in the country. World War II and Japanese occupation. Naga came under Japanese occupation on December 18, 1941 following the Japanese invasion of Legazpi a few days earlier. More than three years later, on April 9, 1945, combined U.S. and Philippine Commonwealth troops under the United States Army, Philippine Commonwealth Army and the Philippine Constabulary, aided by Bicolano guerrilla resistance groups, finally liberated Naga and defeated the Imperial Japanese invaders, thus ending the war.
