Greenhouse gas (GHG) climate change/global warming is one of the most
pressing environmental concerns today.
Small Island States, such as Trinidad
and Tobago, are highly vulnerable to climate change because of their small size
and low elevation, as in the case of this study, which increases their sensitivity to
climate change and limits their ability to adapt.
In fact, the adaptive capacity of
human systems is generally low in Small Island States, and vulnerability
The Petroleum Company of Trinidad and Tobago (PETROTRIN)
recently conducted a detailed vulnerability assessment survey and storm surge
simulation through modelling for the west coast of Trinidad stretching from
Vessigny River in the North to Cap-de-Ville in the South along the Gulf of Paria.
This survey was undertaken so as to identify the impacts of climate driven, sea
level rises and extreme storm surge events on Petrotrinís and Trinmarís
infrastructure and operations.
The methodology used to conduct this
vulnerability assessment survey involved coupling A-OGCM (Atmosphere-
Ocean General Circulation) model simulations of future sea level rises and
TAOS (Total Arbiter of Storms) estimates of storm surges to a GIS-based
inundation and erosion scheme so as to estimate land loss and infrastructure
facilities at risk from inundation and erosion.
The results of the study show that
field installations in Petrotrin at Guapo, such as access roads, pipelines, storage
tanks and even pump jacks and the offshore operations of Trinmar including
offshore platforms, jetties and harbours and administrative buildings would be at
severe risk of inundation and erosion deriving from sea level rises and storm
