The Global Wildfire Challenge & Learning To Live With Fire

2019-04-05 (2021-07-22):  Let us imagine, for a moment, that we are in another dimension … The Twilight Zone …

… and that this is a Positive Energy Building, set in a sprawling, diverse, interconnected and flourishing #Woodland with its ecosystems, flora and fauna … an idealized scene … the Sustainability Idyll

But … is it … ??   What percentage of the world’s population would ever have the opportunity to live this way ???

And … lurking all around this beautiful scene, is an inherent and growing threat to life, property, and those trees, shrubs, and wildlife … #Wildfires / #Bushfires …

The Aim of Sustainable Fire Engineering (#SFE) is to dramatically reduce direct and indirect fire losses in the Human Environment (including the social, built, economic, virtual, and institutional environments) … to protect the Natural Environment … and, within Buildings, to ensure that there is an effective level of Fire Safety for All Users / Occupants, not just for Some, during the full building life cycle.

[ Human Environment:  Anywhere there is, or has been, an intrusion by a human being in the Natural Environment. ]

So … how do we reduce direct and indirect fire losses in the Human Environment … and improve its #Resilience ?

.

A recent publication provides a good platform – a benchmark – to begin this serious conversation …

December 2018 … the International Union of Forest Research Organizations (#IUFRO), which is based in Vienna, published Occasional Paper No. 32: ‘GLOBAL FIRE CHALLENGES IN A WARMING WORLD – Summary Note of a Global Expert Workshop on Fire and Climate Change’ …

GLOBAL FIRE CHALLENGES IN A WARMING WORLD – Summary Note of a Global Expert Workshop on Fire and Climate Change   (PDF File, 4.72MB)

Executive Summary

Today, catastrophic wildfires are increasingly common across the globe.  Recent disasters have attracted media attention and strengthened the perception of wildfires as ‘bad’ events, a plague worsened by climate disruption that has yet to be eradicated.  Although it is true that fire has a destructive potential, the reality of global fire activity depicts a much more complex picture in which fire can be a useful, if not necessary, tool for food security and the preservation of cultural landscapes, as well as a an integral element of many ecosystems and their biodiversity.

Global fire activity is shaped by diverse social, economic, and natural drivers influencing the fire environment.  The culminating complexity of these factors defines, in turn, the likelihood of a landscape to burn and the potential positive or negative outcomes for communities and ecosystems that can result from a blaze.  Although many regions remain understudied, the effects of ongoing climate disruption associated with other planetary changes are already visible, transforming fire activity in ways that are not well understood but are likely to be dramatic, with potential dire consequences for nature, and society in case of #Adaptation failure.

Based on the limited available statistics, there is a growing trend in the cost of wildfires.  In addition to human lives that are lost to flames or smoke, and the billions of euros imputable to firefighting and insurance coverage, the growing interest in costs linked to healthcare, business stability, or the provision of ecosystem services such as drinking-water indicates negative economic consequences impacting countries’ GDP and social stability.  Attempts to evaluate the future costs of wildfire disasters point at a worsening situation, yet the list of possible social and economic effects is incomplete and the magnitude of envisaged impacts is conservative.

Notwithstanding the difficulties inherent to global climate modelling, there is a scientific consensus on the future increase in the frequency of fire-conducive weather associated with drier ecosystems, a mix that will eventually result in more frequent and intense fire activity.  When combined with an ever-growing world population and unsustainable land uses, the conditions leading to fire disaster will only be intensified.  Although fire governance has historically advocated for fire suppression, a ‘NO FIRE’ motto is not an option anymore in the new fire reality.  Current policies aiming at total fire suppression have been shown to be detrimental and are therefore outdated.  The key to wildfire disaster risk reduction in a changing world now lies in learning to live with fire.

Investments in international co-operation, integrated management, local community involvement, cutting-edge technologies, and long-term data collection are critically needed to ensure the future of fire disaster risk mitigation.  Moreover, future land development policies must prioritize the protection and the restoration of natural and cultural landscapes that have been degraded by the inappropriate use of fire or, conversely, by historical fire exclusion; keeping a place for fire in forest resource management and landscape restoration has been shown to be a cost-effective and efficient solution to reduce fire hazard.

Overall, synthesis of globally available scientific evidence revealed the following key issues for Landscape Management and Governance:

  • Climate Disruption, with longer, hotter, and drier fire seasons, in combination with other environmental changes linked to population growth and unsustainable land-use practices, is contributing to extreme wildfire events that exceed existing fire management capacities.  The world is entering a ‘new reality’ that demands new approaches to fire governance.
  • Fire is an inherent feature of the Earth System and many ecosystems, including their fauna, are dependent on it for their long-term survival; nevertheless, ongoing changes in global fire activity in terms of location, intensity, severity, and frequency will have immense costs for biodiversity, ecosystem services, human well-being and livelihoods, and national economies – to extents that have yet to be evaluated.  Investment in social, economic, and environmental monitoring is therefore urgent, especially in under-studied regions.
  • Integrated fire risk reduction is key to adapting to ongoing changes in global fire risk.  Future #Sustainable Fire Risk Mitigation demands integrated region-specific approaches based on a clear understanding of fires in context, population awareness and preparedness, fire surveillance and early-warning systems, adaptive suppression strategies, fire-regime restoration, landscape-scale fuel management, changes to many land use practices, and active restoration of landscapes.
  • Engagement with local communities, land-owners, businesses and public stakeholders – via multiple tiers of governance – is crucial to restore and maintain landscapes that are biodiverse and functional, respectful of local cultures and identities, economically productive, and above all, fire-resilient.
  • People have historically achieved sustainable co-existence with flammable ecosystems and have often used fire as a land-management tool, thereby shaping many modern and long-standing landscapes around the world.  Traditional fire knowledge is thus key to adapting to local changes in fire activity, using known techniques for the reduction of dangerous fuel loads, prescribed burning and sustainable landscape management practices.
  • Building adaptive capacity to confront fires must be based on knowledge of the natural and cultural roles of fire, how they have shaped our modern landscapes, and their importance in the long-term functioning of socio-ecological systems.  Further developments in land-system science, geospatial technologies, and computer modelling will enhance our understanding of the long-term ecological and socio-economic drivers of fire through the widespread collection and distribution of harmonized fire data at the global level.  However, creating and sharing such knowledge requires national and international investments in scientific and operational fire science programmes.
  • Catastrophic fires are undeniably part of our future.  Current scientific estimates are conservative, meaning that changes in fire activity might be worse than anticipated.  We have to act now to mitigate catastrophic fires and limit the occurrence of disastrous situations.  Given disparities but also similarities in the levels of fire risk around the world, and the capacities to manage it, knowledge and technology transfers through international cooperation will be a paramount factor in learning to live with fire.

This Occasional Paper is the result of a large collaborative effort by fire scientists and practitioners who believe that learning to co-exist with changing fire activity is not only possible but necessary if we, as a global society, are to adapt to climate disruption and keep our natural and cultural landscapes healthy, resilient, and safe for the next generations.  The work presented hereafter was developed during, and as follow-up to, the Global Expert Workshop on ‘Fire and Climate Change’ hosted in Vienna, Austria, on 2-4 July 2018.  It stresses the diversity and the complexity of the global fire situation, a situation that is evolving, positively or negatively, in unknown proportions due to global environmental changes — with climate disruption being the most acknowledged manifestation.

Conclusion – Learning To Live With Fire

We live on a flammable planet; although not everything is meant to burn, fire cannot be eliminated.  Ongoing global climate disruption combined with other planetary changes is leading to more frequent and more extreme fires exposing vulnerable societies, economies, and ecosystems to disaster situations.  The recognition of fire activity as a worsening hazard threatening human security is the necessary first step towards international co-operation for the mitigation of disaster risk situations in fire-prone areas.

However, we are not defenceless.  Fire scientists in many regions of the world have been developing successful strategies and tools based on cutting-edge technologies for several years.  Those are now mature enough to be up-scaled and adapted to other geographic contexts as part of national fire management frameworks.  Additionally, integrating existing and future scientific knowledge on climate disruption and changing fire regimes, and systematically collecting long-term data on current and past fire uses will foster better informed decisions, models and enhanced efforts towards Wildfire Disaster Risk Reduction, as well as contribute to the development of Sustainable Anthropocene Fire Regimes.

We hope this paper will be a catalyst for a paradigm shift, so fires are not seen as an enemy to fight but as natural and necessary phenomena, as well as a useful and necessary tool that can often help protect people and nature.  It is paramount to revise, fund, and fulfil future management, research, and governance needs if we are, as world citizens, to trigger a societal change that will help us better live with fires.

The information and insights contained in this Occasional Paper connect together to promote the use of several existing solutions to the problem: defining national fire risk reduction frameworks, collecting and analyzing relevant traditional knowledge and biophysical fire data, investing in fire detection and prediction technologies, involving and preparing stakeholders, and improving fire use and landscape management in ways that help control the fuel load and the spread of fire, while limiting GreenHouse Gas (#GHG) emissions and protecting the communities and the landscapes they live in and often depend on.

The Status Quo is no longer an option; it is time to make Integrated Fire Management the rule rather than the exception.

Sustainable Fire Engineering – Recent Dublin Presentations !

2019-03-19:  Two Conference & Exhibition Events were recently held in Dublin’s City West Convention Centre

2019 City West Summits, Dublin – Colour photograph showing the view over the Exhibition Hall.  Click to enlarge.

.

I was very pleased to make a Presentation at both events, adapted to suit an Irish context, on … ‘Sustainable Fire Engineering – Necessary Professional Transformation For The 21st Century’ … which continues to evolve.

Sustainable Fire Engineering:  The creative, person-centred and ethical Fire Engineering response, in resilient built form and smart systems, to the concept of Sustainable Human and Social Development … the many aspects of which must receive synchronous and balanced consideration !

Presentation Abstract

Annual Fire Losses, both direct and indirect, amount to a very significant percentage of Gross Domestic Product (#GDP) in all economies, whether they are rich or poor … and result in enormous environmental devastation and social disruption.  Some losses have not yet been fully identified, e.g. environmental impact … while others are not yet capable of being fully quantified, e.g. business interruption, brand and reputation damage.  Globally, fire statistics still remain unreliable.  In all cases, however, the waste of valuable human and natural resources caused by preventable fires is unsustainable and no longer acceptable.

From an entirely different perspective … Sustainable Buildings are presenting every society with an innovative and exciting re-interpretation of how a building functions in response to critical energy, environmental, climate change and planetary capacity pressures … an approach which has left the International Fire Engineering and Firefighting Communities far behind in its wake, struggling to develop the necessary ‘creative’ and ‘sustainable’ fire safety strategies.

The Aim of Sustainable Fire Engineering (#SFE) is to dramatically reduce direct and indirect fire losses in the Human Environment (including the social, built, economic, virtual, and institutional environments) … to protect the Natural Environment … and, within buildings, to ensure that there is an effective level of Fire Safety for All Occupants, not just for Some, over the full building life cycle.

The following Priority Themes for SFE lie outside, or beyond, the constrained and limited fire safety objectives of current fire regulations, codes and standards – objectives which do not properly protect society, a fire engineer’s clients, or the facility manager’s organization:

  1. Fire Safety for ALL, not just for Some.  Nobody left behind !
  2. Firefighter Safety.  Everyone goes home !   It is easy to dramatically improve firefighter safety with building design.  So, why haven’t NIST’s 2005 and 2008 WTC 9-11 Critical Recommendations been properly implemented anywhere ?
  3. Property Protection.  Fire damage and post-fire reconstruction/refurbishment are a huge waste of resources.  On the other hand, protection of an organization’s image/brand/reputation is important … and business continuity is essential.  Heritage fire losses can never be replaced.
  4. Environmental Impact. Prevention of a fire is far better than any cure !   But prevention must also begin by specifying ‘clean’ technologies and products.  Low Pressure Water Mist Systems are not only person/environment-friendly and resource efficient … they are absolutely essential in airtight and hyper energy-efficient building types (e.g. LEED, PassivHaus, BREEAM) in order to achieve an effective level of fire safety for all occupants, and firefighters.    [ Note: Environmental Impact Assessment (#EIA) has been superseded by Sustainability Impact Assessment (#SIA).]
  5. Building Innovation, People and Their Interaction.  Fire engineers and firefighters must begin to understand today’s new design strategies.
  6. Sustainable Design and Engineering. Wake up and smell the coffee !   Legislation can only achieve so much.  Spatial planners, building designers and fire engineers must subscribe to a robust Code of Ethics * which is fit for purpose in the Human Environment of the 21st Century.

Sustainable Fire Engineering Solutions are …

  • Adapted to a local context, i.e. climate change/variability/extremes, social need, geography, economy, and culture, etc ;
  • Reliability-based – lessons from real extreme and hybrid events, e.g. 2001 WTC 9-11 Attack, 2008 Mumbai/2015 Paris/2016 Brussels Hive Attacks and the 2011 Fukushima Nuclear Incident, are applied to frontline practice ;
  • Person-centred – real people are placed at the centre of creative endeavours and due consideration is given to their responsible needs, and their health, safety, welfare and security in the Human Environment ;
  • Resilient – functioning must be reliable during normal conditions, and include the ability to withstand, adapt to and absorb unusual disturbance, disruption or damage, and thereafter to quickly return to an enhanced state of function.

Spectacular Dawn over Amandola (FM), in Italy – 28 April 2013 !

2013-05-02:   Yes, that is the moon … yes, that is a rainbow … yes, those are the Sibillini Mountains still sketched with snow … yes, those are the cloud formations and colours at one moment during a spectacular dawn over Amandola at 06.12 hrs on Sunday morning, 28 April 2013 …

Spectacular Dawn over Amandola (FM), in Italy - 28 April 2013

Taking a photograph is a distraction from the ‘real’ experience … it fails to capture and communicate the ‘person-centred’ feeling …

And I can imagine more comfortable words to describe this scene … ‘spiritual’, ‘transcendental’, ‘metaphysical’, ‘mystical’, ‘supernatural’ …

Older People in Emergencies – Urgent Action Required !! (I)

2009-11-25:  In the midst of an economic, financial and fiscal crisis in Ireland … the country has recently been hit by a Major Flood Emergency in the West and South … extending inland almost to the centre.  The emergency will continue over the next few days.

There appears to be no central co-ordination of the response to this National Emergency.  No public guidance or other announcements have been published in the national media.

Further to the full page advertisement promoting the National Older & Bolder Campaign, which was printed on Page 7 of The Irish Times (2009-11-19) … the contents of World Health Organization (WHO) Fact Sheet: ‘Older Persons in Emergencies’, drafted following the 2006 Lebanon Humanitarian Crisis, are both appropriate and particularly relevant for Ireland now …

When dealing with older people in emergencies, a number of issues which might affect them will require special consideration.  Apart from specific chronic disease and disability related issues, two major factors contribute to increased vulnerability of older people in emergencies: the ‘normal’ challenges of physical ageing and social loss, and the ‘environmental’ challenges.  In a crisis, minor impairments which do not interfere with daily functioning in the normal environment can quickly become major handicaps that overwhelm an individual’s capacity to cope.  For instance, an older person with arthritic knees and diminished vision, living alone in a high-rise apartment with no family members or friends nearby, can become incapable of getting food or water or of fleeing danger, and may be overlooked by neighbours.

Specific Issues

There are several specific issues that affect older people, separately or in combination, and which can impact on their ability to respond or react in an emergency.  Awareness of these specific issues by all those giving aid, or surrounding them, will improve interactions.  Knowledge of the age profile in an affected community, as an emergency response is prepared, will help to ensure that older people at risk are identified and that appropriate supplies and services are provided on-site.

The specific issues affecting older people are:

1.   Sensory Deficits (especially vision and hearing)

  • reduced awareness ;
  • difficulty accessing and comprehending visual and auditory information, and responding appropriately ;
  • reduced mobility and risk of disorientation.

2.   Slower Comprehension and Retention of Information (especially new, complex or rapidly delivered information)

  • difficulty accessing information ;
  • difficulties in understanding and acting on risks, warnings, directions ;
  • reduced capacity for self-protection and avoidance of harm ;
  • disorientation in unfamiliar environments ;
  • greater risk for abuse and exploitation ;
  • provision of information in more accessible and structured formats.

3.   Less Efficient Thermoregulation

  • greater susceptibility to hypothermia, hyperthermia and dehydration ;
  • appropriate shelter, clothing and food, as well as adequate fluid intake.

4.   Reduced Functional Ability (poorer balance and reduced speed, psycho-motor co-ordination, strength and resistance)

  • reduced mobility and risk of being housebound ;
  • increased risk of falling ;
  • decreased capacity for self-protection and harm-avoidance ;
  • difficulty getting basic necessities and accessing health facilities, e.g. local clinics ;
  • increased vulnerability to abuse and exploitation.

5.   Difficulties in Urinary Continence

  • need for adequate toilet facilities and continence supplies.

6.   Oral Health & Dental Problems

  • easy-to-eat soft food and fluids may be necessary.

7.   Changes to Patterns of Digestion 

  • need for smaller, more frequent portions of easily-digestible, nutrient-dense food and adequate fluids.

8.   Increased Body Fat Composition, with Decreased Muscle Mass and Metabolic Rates

  • greater sensitivity to certain medications with potential adverse effects on functional ability and cognition.

9.   Greater Prevalence, and Co-Morbidity of Ageing-Related Chronic Disease and Disability (e.g. coronary heart disease, hypertension, stroke, cancers, diabetes, chronic obstructive pulmonary disease, osteoarthritis, osteoporosis, cognitive impairment)

  • need for condition-specific medications, treatments, medical device and assistance aids (oxygen, crutches, walkers, wheelchairs, glasses) ;
  • higher risk for adverse drug reactions.

10.  Weaker and Smaller Social Networks (e.g. widowed, living alone, minimal contact with neighbours, dispersion of family)

  • reduced awareness and comprehension of the situation ;
  • greater risk of social isolation, neglect, abandonment, abuse and exploitation.

11.  Heavy Reliance on Care and Support by Very Few Family Members

  • when essential family support is disrupted, physical and psychological functioning can deteriorate rapidly ;
  • reunification with family is particularly important.

12.  Psycho-Social Issues

  • reactions to loss of home, family and possessions can be more acute for older people who cannot rebuild their lives ;
  • resistance to leaving, and grieving, may be strong.

13.  Reliance of Other Family Members on Older People

  • older people often care for other dependent adults and children and may require resources for others as well as themselves.

Last but not least: Older People should not be considered solely as a Special Needs Group.  From numerous accounts of natural disaster and armed conflict situations, it is known that their knowledge of the community, previous experiences with such events, and position of respect and influence within their families and communities are critical resources in dealing effectively with emergencies.

Sustainable Fire Engineering & Fires in Buildings ?

2009-07-11:   Practical Implementation of Sustainable Human & Social Development … transforming our Human Environment by gradually improving and monitoring ‘Real’ Sustainability Performance … depends entirely on directly applying a Multi-Aspect Understanding of ‘Sustainability’, in a manner which is both balanced and equitable, to all of the many different facets of Sustainable Design.

Therefore … responding ethically and professionally, in built and/or wrought (worked) form, to the still evolving concept of Sustainable Human & Social Development …

        … the specific aim of Sustainable Fire Engineering shall be to design for Maximum Credible Fire & User Scenarios … in order to maintain a proper and satisfactory level of fire safety and protection over the full life cycle of a building.

[Sustainable Fire Engineering can be applied, equally, to other elements of the Built Environment, e.g. means of transport on land or sea.]

As discussed in a previous post … the Minimum Life Cycle of a Sustainable Building is 100 Years.  AND, to prolong Building Life Cycle and maximize Building Usability … such a building must be Flexible and Adaptable with regard to internal layout, Accessible for People with Activity Limitations (2001 WHO ICF) … and Structurally Robust.

 

Maximum Credible Fire Scenario:

A sequence of events during a ‘real’ fire incident in a building – related to design, construction, occupancy, fire loads, ignition sources, spatial geometry, fire protection measures (both passive and active) … and an adverse, but reasonable to anticipate, operation and management status – which culminates in fire conditions which are severe, but reasonable to anticipate over a complete building life cycle.

 

Maximum Credible User Scenario:

Indicates building user conditions which are also severe but reasonable to anticipate over a complete building life cycle, i.e. …

  • the Number of People Using a Building increases, on occasions which cannot be specified, to 120% of Calculated Maximum Building Capacity ;

             and

  • 10% of People Using the Building (occupants, visitors & other users) have an Impairment (visual or hearing, physical function, psychological, mental or cognitive … with some impairments not being identifiable, e.g. anosognosia).

 

Sustainable Fire Engineering Strategy:

A coherent and purposeful arrangement of fire protection and fire prevention measures which is developed in order to meet specified Sustainable Fire Engineering Design Objectives.

In designing a building for conditions of fire, and its aftermath, project-specific Sustainable Fire Engineering Design Objectives typically cover the following spectrum of concerns …

  • Protection of the Health and Safety of All Building Users … including people with activity limitations, visitors to the building who may be unfamiliar with its layout, and contractors or product/service suppliers temporarily engaged in work or business transactions on the premises ;
  • Protection of Property … including the building, its contents, and adjoining or adjacent properties, from loss or damage ;
  • Protection of the Health and Safety of Firefighters, Rescue Teams and other First Response Personnel ;
  • Protection of the Natural Environment from Harm, i.e. adverse impacts ;
  • Facility, Ease and Cost of carrying out Effective Repair, Refurbishment and Reconstruction Works after the Fire ;
  • Sustainability of the Human Environment (Social, Built, Virtual, Economic … ).

 

Human Health:

A state of complete physical, mental and social wellbeing, and not merely the absence of disease or infirmity.   (World Health Organization)
