T&TEC HSE Week Presentation

  1. 1. Capturing the relationship between our habits and the impacts on the environment, weather, climate... (c) H. Anderson. T&T Meteorological Service29/01/2015
  2. 2. Two important aspects 1. Understanding the concept of ‘Risk’ 2. Examining humanity’s relationship with the environment, specifically weather and climate © H. Anderson. T&T Meteorological Service
  3. 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. 4. Vulnerability  Being prone or susceptible to damage or injury (c) H. Anderson. T&T Meteorological Service Active Volcano City
  5. 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. 6. Disaster  A sudden or great misfortune  Calamity  Complete failure (c) H. Anderson. T&T Meteorological Service
  7. 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. 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. 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. 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. 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. 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. 13. Is Climate Change Real? Is it our fault? (c) H. Anderson. T&T Meteorological Service
  14. 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. 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
  16. 16. Minimising Risk Reducing Vulnerability (c) H. Anderson. T&T Meteorological Service
  17. 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. 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. 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. 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
  21. 21. What do we do?  Manage our lands more effectively – proper planning and enforcement of policies/regulations/legislation  Become more environmentally conscious – indiscriminate dumping of waste, proper disposal of solid and liquid waste  Protect our vital watersheds from fires and illegal use since they protect us from flooding  Reforest damaged hillsides  Reassess and improve our infrastructure to cope with observed changes © H. Anderson. T&T Meteorological Service
  22. 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. 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 (c) H. Anderson. T&T Meteorological Service
