T&TEC HSE Week Presentation
1. Capturing the relationship between our habits and the
impacts on the environment, weather, climate...

3. What are Hazards?
Hazards are phenomena or events that pose the
possibility of loss of life, or damage to property and
infrastructure.
(c) H. Anderson. T&T Meteorological Service
Examples include:
Lightning strikes, flooding,
strong gusty winds, tropical
cyclones, earthquakes,
volcanic eruptions, civil
unrest or political instability,
terrorism, etc...
4. Vulnerability
Being prone or susceptible to damage or injury
(c) H. Anderson. T&T Meteorological Service
Active Volcano
City
5. Risk
The chance or possibility of loss or bad consequence
Exposure to danger
(c) H. Anderson. T&T Meteorological Service
For example:
1. You’re house is
at risk of
burning;
2. We are at risk of
being flooded
out.
6. Disaster
A sudden or great misfortune
Calamity
Complete failure
(c) H. Anderson. T&T Meteorological Service
7. Disaster
For a Disaster to have occurred human life or property
must incurred some loss.
Disasters require Vulnerable groups
These Vulnerable groups are at some Risk
(c) H. Anderson. T&T Meteorological Service
Vulnerable
people/
property
High Risk Disaster!
8. Disasters are a function of Risk
As Risk increases so does the potential for loss of lives
or damage to property in any disaster.
(c) H. Anderson. T&T Meteorological Service
9. Meteorological hazards common to
Trinidad and Tobago
Heavy/Intense Rainfall
Extended Rainfall
Strong/Gusty Winds
Lightning Strikes
Hurricanes
Tropical Storms
Storm Surges
Dangerous Seas
Land Erosion
Riverine Flooding
Flash Floods
Landslides/Land Slips
Mudslides
Funnel Clouds/
Waterspouts
Low Visibility
Saharan Dust
Smoke/Bush and Forest
Fires
Any more you can think
of?
(c) H. Anderson. T&T Meteorological Service
10. How Meteorological Hazards Affect
Us
Can cause the loss of human lives
Loss of property
Damages infrastructure and communications
Harms the economy
Can cause social unrest/civil disobedience/lawlessness
Breakdown of social bonds and structures
Health problems, eg. Asthma, Pathogenic Diseases
such as Dengue Fever, Cholera, etc...
Huge rebuilding and recovery costs
(c) H. Anderson. T&T Meteorological Service
11. Our Relationship with the
Environment: Weather and Climate
Very complex and iterative
Humans depend on the environment for our
sustenance/survival – food, water, protection,
livelihoods
However our use of the environment has direct
impacts on the way the environment expresses itself:
scenery, temperature, rainfall timing and receipts, sea
level, and many more...
(c) H. Anderson. T&T Meteorological Service
12. Climate Change
Climate change is the change in our weather patterns
that are occurring because of an increase in the earth's
average temperature
Otherwise known as Global Warming
It is said to be happening as a result of increasing
Carbon Dioxide levels in the Atmosphere...
Carbon Dioxide that Humans have put there... ?
(c) H. Anderson. T&T Meteorological Service
13. Is Climate Change Real? Is it our
fault?
(c) H. Anderson. T&T Meteorological Service
14. Potential Impacts of Climate
Change
Increasing ambient temperatures
Rising Sea-levels and Temperatures
Changing climate and weather patterns:
More intense rainfall events?
Drier Dry Seasons?
More Hurricane Activity?
Threats to Water Resources
and Agriculture/Food Production
(c) H. Anderson. T&T Meteorological Service
15. Still a Need to Minimise Risk
Utilisation
of Natural
Resources
Pollution &
Environmental
Degradation
Climate
Change
Changing
Weather
Patterns
Diminished
Resource Base
•As mentioned before
humans and the
environment have a
dynamic relationship...
•We depend on the
environment for
survival, and the
environment responds to
our actions
(c) H. Anderson. T&T Meteorological Service
17. How to Minimise Vulnerability?
Case Study: Trinidad 2010
Conditions:
2010 Dry Season one of driest on record
(March 2010 driest on record)
Northern Range was on fire for
extended periods due to indiscriminate
lighting of fires – hunters, slash & burn
agriculture, cigarettes
Clearing of hillsides and unplanned
developments
Many questionable “approved”
developments
Inadequate infrastructure
18. How to Minimise Vulnerability?
Case Study: Trinidad 2010
Results: During the Dry Season
Smoke-filled atmosphere
Loss of forests on Northern Range
Loss of habitats and animal life
High daytime and night-time temperatures due to an
enhanced greenhouse effect
Onset of Asthma, Sinuses, and other breathing difficulties
(c) H. Anderson. T&T Meteorological Service
19. How to Minimise Vulnerability?
Case Study: Trinidad 2010
Results: During the Wet Season
Loss of soil infiltration capacity through the loss of vegetative
cover
High surface runoff and moderate/severe episodes of flash
flooding
High levels of sedimentation in rivers, streams and drains,
resulting is widespread flooding
Damage to property and infrastructure
Loss of life (one)
(c) H. Anderson. T&T Meteorological Service
20. Personal habits & their impact
• Deteriorated visual quality, clogged drains
• Flooding, loss of life and property, loss of wildlife,
lawlessness
Indiscriminate dumping of
plastic bottles, Styrofoam
plates/cups, tyres, appliances
• Increased surface flow of water, floods, landslips
• Loss of life and damage to property at site and
downstream, reduced resource base, damaged
infrastructure
Lighting indiscriminate fires,
clearing hillside land, farming
on steep slopes
• Reduces vegetative cover and increases surface flow,
increasing possibility of flooding, landslips, loss of
life and property, damaged infrastructure
• Poisons aquatic life, reduced drinking water quality
Building in the Hills without
permission, uncontrolled use
of pesticides/herbicides, etc
• Uses more fuel/energy, produces greater amounts of
Carbon Dioxide and other pollutants
• Enhances global warming, rising sea levels, habitat
loss, “freak” weather risk increases, lives at risk
Leaving unnecessary lights on,
running the a/c when not in
the room, driving
unnecessarily, etc
22. What do we do?
Claim ownership of the environment. It is not “they”
or “the government” that owns it. YOU own it.
Assess your own vulnerability: Observe recent flood
water levels; identify if you live in a flood plain; look
out for tilted utility poles; check for clogged or
inadequate drains
Become socially active: demand from your
parliamentary representative that they remedy
possible vulnerabilities
Don’t procrastinate
(c) H. Anderson. T&T Meteorological Service
23. Remember...
You depend on the environment for your needs (water,
clean air, food, etc.)
The environment naturally has built in mechanisms to
deal with weather/climatic vagaries
It is our manipulation of the environment that puts us
at risk, in addition to building our settlements in
disaster-prone areas
A Disaster can be mitigated by reducing Risk and
Vulnerability
