Metro Cebu has persisted in the regional planning of the Central Visayas Administrative Region (Region VII) since the early 1980s (Mercado, 1998). Prior to the formation of the MCDCB in 2011, there was no formal basis for metropolitan planning and development. Today, seven city and six municipal LGUs form Metro Cebu. In economic terms, Metro Cebu is a regionally prominent and growing centre of commerce, trade, education and industry. During the last 20 years, Metro Cebu has transformed into a global hub for furniture-making, tourism, business processing services and industry. It is also the location of the Philippines’ second largest airport and a regionally significant port.
The Island of Cebu lies in the centre of the Philippine archipelago. It is characterised by limestone plateaus, hills and mountain ranges reaching 900 metres above sea level. The island is equally characterised by long and narrow coastal plains (it is 196 km long, 32 km across at its widest point and covers an area of 4 500 km2). In the City of Cebu, these low lying areas extend a few kilometres inland from the coast and represent about 8% or 25 km2 of the total land area. Despite the small area, this land hosts approximately two-thirds of the city’s population (Cebu City, 2010). This pattern appears to be repeated across the breadth of Metro Cebu’s 12 other LGUs. Cebu is surrounded by a further 170 islands, the largest being Mactan Island which is located in close proximity to the east of Cebu City and connected via two large bridges (construction of a third bridge is anticipated in the near-term to alleviate peak-hour traffic congestion).
The Philippines is situated in an acutely high risk area and is consistently ranked among the three most vulnerable countries in the world according to the World Risk Report (UNU, 2015). For example, between 1995 and 2015, 274 disasters afflicted the country, the fourth highest total globally after the United States (472), China (441) and India (288) (UNISDR, 2015). Moreover, the financial impact these natural hazards impose is significant. Metro Cebu is afflicted by geophysical and climate-related natural hazards, and is characterized by a tropical climate of dry and monsoonal seasons. It regularly experiences severe flooding, especially after heavy precipitation during the wet season from June to November and seasonal tropical storms. On the one hand, Metro Cebu’s topography is undulating and mountainous with heights reaching 900 metres above sea level. On the other hand, as already mentioned, low lying coastal land extending a few kilometres inland hosts a large proportion of the population. The challenge the local geography imposes, in combination with heavy precipitation, leads to severe flooding in low lying areas and landslides in steeply sloping zones as well, such as at the ‘foot’ of the Mananga Watershed (Marvette, 2014). Moreover, it should be noted that Cebu faces longer-term, ‘slow-onset’ climate change impacts including heat waves, sea level rise, water and food security issues, and saltwater intrusion into coastal aquifers and water wells.
Cebu is also subjected to occasional typhoons. In November 2013, Super Typhoon Haiyan (Yolanda) became a Category 5 typhoon, the strongest ever recorded at the time, with wind gusts in excess of 300 kilometres per hour and an associated storm surge that reached as high as 3.5 metres along some coastlines with more vulnerable coastal bathometric profiles (NDRRMC, 2013a). In Cebu, it made landfall twice in the north of Cebu Island with as many as 1 million people evacuated beforehand (UNISDR, 2016). As a country, more than 1.1 million houses were damaged, half of which were completely destroyed. It also killed over 6 300 people, left more than two million homeless, and affected over 13 million people in the Philippines (NDRRMC, 2013a). In total, over USD 12-15 billion in damages were recorded, which is small in comparison to other recent disasters in more developed countries due to the higher asset values. Nonetheless, the Typhoon Haiyan damage bill represented about 5% of the Philippines’ total GDP in 2013 (Bloomberg, 2013). An equivalent level of damage to the United States of America’s economy would amount to USD 850-900 billion. In terms of insured damages, an analysis by Kinetic Analysis Corporation estimated that only about 10-15% of the total losses in the Philippines were insured compared with about 50% for Superstorm Sandy (United States), which led to around $50 billion in economic damages (Bloomberg, 2013).
The metropolitan area also lies in close proximity to three fault lines including the North Bohol Fault which in addition to soft soil composition in certain quarters, exacerbate the metropolitan area’s vulnerability to disaster that would otherwise be reduced if one of these two factors were not present (Silva, 2015). In 2013, Cebu experienced a magnitude 7.2 Bohol earthquake. Although the metropolitan area was not at its epicentre, it caused USD 2 billion in damages and affected 870 000 people (NDRRMC, 2013b). In the broader region of Cebu, the earthquake also damaged nearly 1 000 houses, in addition to local infrastructure and community facilities.
