Introduction to Disaster Risk Management Module 01: Basic Concepts of DRM — Where We Stand Presentation Script

Module Objectives

This introductory module will: • Give an overview of natural hazards and disasters all over the world; • Provide definitions and frameworks, to assure a basic common knowledge

and consistency, • Introduce the most significant players in the international context, and • Present coping techniques: showing differences between former and current

practices. Introduction

Earthquakes, storms, and other hazards killed about 3.3 million people between 1970 and 2010, which is an annual average of 82,500 deaths worldwide in a typical year (NHUD report, 2010). Disaster risk arises when hazards interact with physical, social, economic and environmental vulnerabilities. Events of hydro‐meteorological origin constitute the large majority of disasters. Despite the growing understanding and acceptance of the importance of disaster risk reduction and increased disaster response capacities, disasters and in particular the management and reduction of risk continue to pose a global challenge.

Definition and Criteria

For a disaster to be entered into the EM –DAT – a specialized disaster database, at least one of the following criteria must be fulfilled (Red Cross, 2010):

• 10 or more people reported killed (missing or presumed dead); • 100 or more people reported affected; • Declaration of a state of emergency; and/or • Call for international assistance.

Natural vs. Technological Disasters

In 2007 a new classification was introduced in EM –DAT. This classification is a first step in the development of a standardized classification of disasters. It distinguishes two categories of disasters: natural and technological.

Natural Disasters are (Red Cross, 2010): • Biological – which comprehends insect infestations, epidemics and animal

attacks;

• Geophysical – earthquakes and tsunamis, volcanic eruptions, dry mass movements, such as avalanches, landslides, rock falls and subsidence of geophysical origin;

• Climatological – droughts and associated food scarcity, extreme temperatures and wildfires;

• Hydrological – floods, inundations, water logs, surges; and • Meteorological – storms.

Technological Disasters are: • Industrial Accidents: ‐ such as chemical spills, collapse of industrial

infrastructures, explosions, fires, gas leaks, poisoning, radiation; • Transport accidents – by air, road, rail or water; and • Miscellaneous – this comprehends collapse of domestic/non industrial

structures, explosions, fires, etc.

This course focuses only on Natural disasters. Key caveats with disasters data include the lack of standardized collection methodologies and definitions (Red Cross, 2010). Data are not always complete, and generally are not collected for statistical purposes, thus the quality of completion may vary according to the type of disaster, country, collector (national or international agencies, public or private entities etc.).

Natural Disasters affect all regions

Disasters affect all regions. East Asia has been hit by the highest number of disasters (more than 2,000). Floods and storms are the most common, while droughts much less so (except in Africa). Deaths are more concentrated: droughts in Africa are the deadliest; storms in East and South Asia also take many lives.

Differences across countries suggest that some countries prevent disasters better than others. For example, the contrast in the death toll in Haiti and the Dominican Republic, sharing the same island and storms, underscores the point that disasters are manmade, not natural.

We are capable of reducing the death toll even in poor countries: moving food by

averts a famine despite droughts; early warning systems reduce deaths caused storms and floods, and so on (NHUD Report, 2010).

Central and Latin American, East Asia and Europe share the highest percentage ofearthquakes (more than 20% per region), while extreme temperature are becoming a serious threat in Continental Europe and South Asia (NHUD Re2010).

multiple hazards, though the importance of each differs. Earthquakes and volcanoes (geophysical hazards) tend to cluster along fault boundaries characterized by mountainous terrain. Floods, cyclones, and landslides (hydrometeorological hazards) affect the eastern coastal regions of the major continents as well as some interior regions of North and South America,and Asia. Drought is more widely dispersed across the semiarid tropics.

Many countries in harm’s way have managed to protect their population over time (NHUD Report, 2010). Rover the last 40 years were in poor countries. Damage, however, may be rising in absolute terms, with earthquakes and storms causing the most of it. Middle‐income countries are particularly vulnerable. Mmay reflect greater exposure to hazards, or better reporting in recent years, or both.

large and rapidly growing cities in poor countries struggle to provide public services, including disaster prevention.

Many scholars believe that “Rising absolute damage is plausible, considering the increased exposure from urbanization”.

Deaths from Disasters

Areas in the map reflect cumulative deaths from different type of disasters for 1970 to 2010 (NHUD Report, 2010). Deaths seem to reduce over time in Latin America, North American and Middle East, while increasing in East Asia and Africa. Africa looms as large as East Asia, and the Americas shrink (the north to almost nothing).

When those areas reflect economic damages and losses instead that population death, Africa shrinks and middle‐income and high‐income countries expand, such as North America (Gulf coast), Middle East (Morocco, Libya and Arabic Peninsula) and East Asia (Australia, China and Indonesia).

Damage on the rise in the last two decades

The annual global damage from disasters between 1970 and 2010—adjusted for inflation—fluctuates like deaths but is also rising in spurts. Damage in the recent two decades is significantly greater than in the earlier decades. This could reflect greater exposure, or better reporting, or both.

Most of the damage is from storms, earthquakes, and floods—in that order. In addition to the economic costs of disasters, there are social and environmental impacts that are many times difficult to quantify. Some examples of social and environmental impacts of disasters include: loss of human life, damage to the environment, losses of natural habitats and destruction of ecosystems, disruption of communities and family life, loss of cultural heritage assets, unemployment, and migration. Disasters tend to have differential impacts on men and women, and gender is an important issue to consider in recovering as well preventing damages and losses from disasters.

Humanitarian Assistance

Donors usually respond to disasters after they strike: about a fifth of total humanitarian aid between 2000 and 2008 was devoted to spending on disaster relief and response. The share of humanitarian funding going to prevention is small but increasing—from about 0.1 percent in 2001 to 0.7 percent in 2008.

of 16


However, prevention activities often imply long‐term development expenditures…………..whereas the focus of humanitarian aid—already a tiny part of official development aid—is immediate relief and response. Donors concerned with prevention could earmark official development aid (rather than humanitarian aid) for prevention‐related activities.

And such aid, if used effectively, could reduce issues arising from the Samaritan’s dilemma: the inability to deny help following a disaster to those who have not taken sufficient prevention measures.

Other Game Players

Many scholars suspect that climate change is influencing the occurrence and impact of natural hazards, mainly because the number and severity of disasters around the world has been increasing (UN ISDR 2009, Munich RE, 2010 as quoted by Bouwer, 2010). Climate change occurs because of high and low frequency natural variations and because of atmospheric pollution through anthropogenic greenhouse gas emissions.

The knowledge about the impacts of climate change on weather hazards has improved considerably during the last few years and recent changes in temperature and rainfall that are being observed have partly been caused by greenhouse gas emissions (IPCC, 2007).

Disasters however are defined by the disruption of the functioning society, involving widespread human, material, economic or environmental losses, and this is largely influenced by population and their location (Bouwer, 2010).

New players such as climate variability, changes in temperature and rainfall patterns, as well as population density, poverty and geo‐physical characteristics are playing major roles in shaping the new era of disasters.

Coping with Disasters

Natural disasters are regarded as the ultimate expression of destructive forces of nature. In the past, disasters have be seen as external events that were not preventable not even forecastable. Most of the responses were based on the use of indigenous knowledge the elderly used to share generation after generation such as early warning, rainwater harvesting, flood protection (especially the handmade ones), cropping patterns, thrift and credit.

of 16


Neither dedicated institutions, nor agencies at local, provincial or national level were designed to cope with disasters and lack of coordination among agencies was a common denominator. Institutions that prevent damage develop more slowly than assets as countries urbanize and prosper. But this is changed drastically: even poor countries can undertake effective prevention, and more can rise to the challenge of doing so.

We will always live on a restless planet with natural hazards covering the gamut of flood, inundation, wind storm, earthquake, tsunamis etc. Today more than ever, communities across the globe know more and can do more to take actions to reduce the devastating consequences of natural disasters left unchecked.

Governments are now able to assess damage and losses after a disaster (and such assessments differ in scope, purpose, and technique). Better access to scientific information and more sophisticated technologies allow better assessments.

Measuring damage is tricky, prone to both overestimation (for example, double counting) and underestimation (it is difficult to value loss of life, or damage to the environment). Biases also affect the accuracy of estimates, especially when the prospect of aid affects incentives.

Accurate measurement is more likely when its purpose is clear, though some items of interest cannot be measured. Damage assessments have multiple and often overlapping purposes. They could guide government relief (such as how much to spend on alleviating the victims’ suffering, knowing that other spending must be cut or taxes raised). They could show how to hasten economic recovery or identify specific measures to improve prevention.

Do we have all information?

People are often guided in their prevention decisions by information on hazards, yet the seemingly simple act of collecting and providing information is sometimes a struggle. While some countries attempt to collect and archive their hazard data, efforts are generally inconsistent or insufficient.

Specifically, there are no universal standards for archiving environmental parameters for defining hazards and related data. Data exchange, hazard analysis, and hazard mapping thus become difficult.

As presented in this slide, few countries collect and archive data on hazards—even though technological advances such as the abundance of free, simple, and open source software (for example, PostGIS, Geoserver, Mapserver, the GeoNode.org project) should make collecting and sharing information easy.

And even where information is collected, it is not always shared, even though sharing information on hazards involves relatively little expense because some government agencies already collect and analyze data on hazard risks.

Systematic mechanisms for tracking information related to the changing nature of risk, and translating it into risk‐related property valuations, would go a long way to increase the incentives for prevention. Making maps of flood plains and

seismic fault lines easily accessible would make developers and property owners more aware of the risks—and more motivated to build appropriately. Collecting data on weather and climate is also integral to producing accurate forecasts (NHUD report, 2010).

Players in the International Community

When disasters struck many players come to help recovering and reconstructing. First is the GFDRR – Global facility for disaster risk reduction and reconstruction.

The World Bank and the Regional Development Bank are also involved in loss and damage assessments and recovering and reconstruction activities and projects – from infrastructure to governance.

The ProVention Consortium, which is a global coalition of international organizations, academic institutions, the private & public sectors, and civil society organizations dedicated to increasing the safety of vulnerable communities and to reducing the impact of disasters in developing countries. For more information, please visit its website at http://www.proventionconsortium.org.

Other partners include the International Strategy for Disaster Reduction, which is the United Nations platform for disaster risk reduction, and the International Federation of Red Cross and Red Crescent Societies, which is working to bridge the gap between relief and development efforts and currently serves as Secretariat to the ProVention Consortium.

Established in 2006, the Global Facility for Disaster Reduction and Recovery (GFDRR) is a partnership of 36 countries and 6 international organizations committed to helping developing countries reduce their vulnerability to natural hazards and adapt to climate change. The partnership’s mission is to mainstream disaster risk reduction (DRR) and climate change adaptation (CCA) in country development strategies by supporting a country‐led and managed implementation of the Hyogo Framework for Action.

The GFDRR is managed by the World Bank on behalf of the participating donors and other partnering stakeholders. The GFDRR operates through multiple donor funds to enable low‐ and middle‐income countries that are at most risk to mainstream disaster reduction in national development strategies and plans to achieve the Millennium Development Goals.

The Hyogo Framework of Action

In January 2005, 168 Governments adopted a 10‐year plan to make the world safer from natural hazards at the Word Conference on Disaster Reduction, held in Kobe, Hyogo, Japan.

The Hyogo Framework for Action (HFA) is a global blueprint for disaster risk reduction efforts during the next decade. Its goal is to substantially reduce disaster losses by 2015 ‐ in lives, and in the social, economic, and environmental assets of communities and countries.

The Framework offers guiding principles, priorities for action, and practical means for achieving disaster resilience for vulnerable communities. Priorities for action include: 1. Ensure that disaster risk reduction is a national and a local priority with a strong

institutional basis for implementation. 2. Identify, assess and monitor disaster risks and enhance early warning. 3. Use knowledge, innovation and education to build a culture of safety and

resilience at all levels. 4. Reduce the underlying risk factors. 5. Strengthen disaster preparedness for effective response at all levels.

The Hyogo Framework explains how there is a need to enhance international and regional cooperation and assistance in the field of disaster risk reduction through, inter alia:

• The transfer of knowledge, technology and expertise to enhance capacity

building for disaster risk reduction • The sharing of research findings,

lessons learned and best practices • The compilation of information on

disaster risk and impact for all scales of disasters in a way that can inform sustainable development and disaster risk reduction

• Appropriate support in order to enhance governance for disaster risk reduction, for awareness‐raising initiatives and for capacity‐development measures at all levels, in order to improve the disaster resilience of developing countries

• Financial assistance to reduce existing risks and to avoid the generation of new risks.

Summary

This introductory module provided: • An overview of natural hazards and disasters • most important definitions and frameworks • introduced the most significant players in the international context, and • described coping techniques: former vs. current practices.

Main Interventions

There is now international acknowledgement that efforts to reduce disaster risks must be systematically integrated into policies, plans and programs for sustainable development and poverty reduction, and supported through bilateral, regional and international cooperation, including partnerships. Sustainable development, poverty reduction, good governance and disaster risk reduction are mutually supportive objectives, and in order to meet the challenges ahead, accelerated efforts must be made to build the necessary capacities at the community and national levels to manage and reduce risk.

Disaster Risk Management is composed by three main types of interventions which are recovering, reconstructing and preventing risks, damages and losses. Those interventions will be described and exploited in details in the next Presentation.
