NATURAL HAZARDS ASSESSMENT: FIRST STEP TOWARDS RISK ASSESSMENT

To see presentations from the Haiti Session at the Understanding Risk conference, please click HERE.

“Disaster Risk Management” (DRM) has been differentiated from “Financial Risk Management” (FRM). As we have been able to witness nowadays, economists and financial “experts”, when colluded with politicians are able to create disasters of enormous proportions, sometimes beyond nature’s power. Let’s then grant their creativity with a supremacy in destructive power. Risk Management (RM) as we know it, refers to the convolute relationship between hazards and vulnerability. As we can also observe, natural, socio-natural and anthropogenic hazards, when mixed with social, environmental, economic and governance vulnerabilities, have certainly not yet reached their peak in destructive power. There is far more to be seen in the future. This circumstance poses a certain number of questions whose answers are far from being complete.

Recent significant events in Latin America, the Caribbean and perhaps in other regions of the world have shown that considerable damage could have been avoided, or at least reduced from the social, environmental and economic standpoints if only a view on risk, more than to disasters would had been applied. According to several sources around 2/3 of the total damage could have been spared by using space (land, territory) more wisely, taking better care of the environment and natural resources, and by offering more options to the chronic impoverishment of our populations. These three closely interlinked factors have two common keys, most of the time not well understood nor materialized: policy and strategy.

Disasters are socially built; they are the product of a misconception of development processes and a mismanagement of risk. Their evident social, economic and environmental consequences lead us to ask: Has DRM been effective? Where are we going with DRM? Is it true that “our” risk management should always have to be benchmarked to “disaster reduction”? Why should we continue to call it DRM instead of RM? A ready-made solution has been to propose international agreements and scopes (e.g. Kyoto, Hyogo, IPCC). But even if this trend has been effective in raising awareness, it should be asked whether success has been achieved, if there is really a solid, robust sustainable drive, or if it is only conjectural and ephemeral.

The most “à la mode” issue is of course climate change (CC): Why and how has it taken more attention than climate variability (CV)?, the latter being, at least for the time being, far more damaging and the cause of a higher jeopardy to the development and well-being of most nations in the world. As proposed by the Working Group I of the Fourth Assessment Report (FAR-IPCC): “…the scientific consensus voiced that warming of the climate system is unequivocal…” Further “…most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to observed increases in anthropogenic greenhouse gas concentrations…” Are these really so “unequivocal” truths? Or are there some misconceptions involved? Does CC really deserve that “unequivocal” priority?

What is then to be done about other hazards, natural, socio-natural (induced) and anthropogenic, not related to climate change: seismicity, volcanism, external geodynamics, hydro-meteorological, climate variability, technological? Haven’t they caused and won’t they continue to cause, at least for the time being, far more damage than CC? (i.e. Haiti, Chile, Mexicali...) Should we pay less attention to them just because some international organisations, lobbyist groups and influential politicians decreed it a supreme priority? Again, a renewed effort in settling down a clear and sound RM policy and strategy is required. The first step is to clarify that RM is not a part of Climate Change Adaptation (CCA), but fully the other way around.

Engineering and scientific communities, even by being able to read Nature’s processes, and by having reached a considerable knowledge on hazards, vulnerability and risk, have not yet brought forward a politically effective risk communication drive. We simply do not have enough persuasive power. Risk mapping, space-time modelling and scenarios are not yet fully considered, perhaps because there is something wrong or weak in the way we address the topic and we stress our arguments. By way of an example: Early warning. Isn’t this a pleonasm? Is warning useful if not made “early”? Unfortunately, early warning systems, most of them only mere surveillance devices, have also become a doubtful DRM panacea, but with a promising market development future. They require further consideration and development.

It is therefore evident that RM requires new energy, vision and stamina to place it as an integral cross-cutting policy and to clear away its pervasive myths. Realities and challenges are already pressing and will not give us any time-losing waiver. There is not a single order of priorities because they have to be defined according to the mutating realities and circumstances of each nation and community. However, it seems promising to incorporate RM into national and sub-national development policies as a transversal multi-sectoral axis in land use and in public and private investment. Mitigation should be inspired on the definition of “accepted” as compared to “acceptable” risk thresholds, by metrics establishing sound Cost/Benefit ratios and future loss assessments. But the most important paradigmatic change would be to associate RM to development planning, separated from “disaster management”.

In our opinion, Risk (excluding tekhnogenesis) involves three factors: 1. existing natural hazard of territory, 2. it's probability and 3. value of infrastructure . Natural hazard defined as sum of geological and meteorological hazard. Geological hazard is the only constant factor from all three (they do not change for hundreds of years). Value of infrastructure (for example decreasing of fixed property), probability of realization GeoHazard and meteorological hazards can change. Geological servises of different countries are researching separate dangerous geological processes. Therefore there are three problems : How to transfer features of a single geoprocess to universal scale of GH. How to get complex assessment GH (for example how can we compare seismically and subsiding hazard). Third problem, is how to make this assessment understandable not only for geologists, but for managers and government. In our institute was developed method, which helps to solve these problems. GIS Map of GH of North Caucasus was created with using this method. This method was also used for assessment hazard of accident on main gas pipeline of European part of Russia. We hope, our experience can help other countries to solve the same problems.

Is there anybody who can help me informing about any software that can help simulating/modeling building collapse, debris generation and road blockage in any community or the entire city due to different scenario based earthquake

En castellano, siguiendo la recomendación de Rosalba: En cuanto a la catástrofe ambiental de Haití, voy a recomendar la lectura de "Collapse: How Societies Choose to Fail or Succeed” (Colapso: Cómo las sociedades eligen fracasar o tener éxito), de Jared Diamon. Se examina una serie de civilizaciones pasadas, en un intento de identificar por qué se derrumbaron o tuvieron éxito, y expone lo que las sociedades contemporáneas se puede aprender de estos ejemplos históricos. Se argumenta en contra de la cultura tradicional de las explicaciones históricas-por el fracaso de las sociedades del pasado y en su lugar se centra en los factores ecológicos. Entre las sociedades que él considera, están los Noruegos y los Inuit de Groenlandia, los Mayas, los Anasazi (EE.UU.), los indígenas de Rapa Nui (Isla de Pascua), Japón, Haití, República Dominicana, y el Estado de Montana (EE.UU.).

Regarding the environmental catastrophe of Haiti, I will recommend the reading of “Collapse: How Societies Choose to Fail or Succeed”, by Jared Diamon. He examines a range of past civilizations in an attempt to identify why they either collapsed or succeeded, and considers what contemporary societies can learn from these historical examples. He argues against traditional culture-historical explanations for the failure of past societies, and instead focuses on ecological factors. Among the societies he considers are the Norse and Inuit of Greenland, the Maya, the Anasazi (USA), the indigenous people of Rapa Nui (Easter Island), Japan, Haiti, the Dominican Republic, and modern Montana.

Is the environmental degradation in Haiti is enough to constitute a hazard in itself?This speaks to the intersection between Risk, Hazards and Vulnerability. Because of the complexities of Haiti's post-colonial history, it is not enough to only look at the geophysical hazards facing the country (cyclones, earthquakes, drought, etc.), but how they are intimately linked with a history of slave rebellion, land fragmentation, and international debt. Deforestation affects soil stabilization, which in turn affects the ability of people to use it as an agricultural resource. Furthermore, we are examining evidence that rapid soil erosion and subsequent deposition in the coastal zone was the cause of the tsunami that hit the coast east of Grand Goave during the 12 January 2010 earthquake. Was that tsunami a geophysical hazard or a man-made hazard?

We had access to two geo-viewers which were developed for Haiti, the one by ESRI (http://www.esri.com/haiti/), and the 3D-UDOP geo-viewer elaborated by Thermopylae Sciences and Technology for South Comm. 3D-UDOP is framed in the Google earth environment, as has been able to set up an easy to use layering system that allows the user to overlay information from a variety of sources already available (http://3dudop.org/haiti/).

UN-SPIDER promotes the use of space-based information for both disaster risk management (including preparedness) and emergency response. In the case of Haiti, the SpaceAid framework established a dedicated webpage to Haiti containing information on the satellites that were tasked and the type of sensors used, as well as links to providers and generators of information on Haiti which included damage assessments. The link is: www.un-spider.org/haiti. However, a subsequent visit to Haiti by UN-SPIDER led to the conclusion that it was mostly UN and US agencies which had enough internet bandwidth to download imagery, rather than national agencies such as CNIGS.

Perfecto... las personas que desen hacer comentarios en español, están invitadas y también son bienvenidas, al igual que sus aportes...!!! 
Rosalba Barrios
Sergio, it would be great if this group could open discussions in spanish also, I think it would easy the communication for more people that could be interested. Thanks! 
Sergio Mora
Natural hazards do not stop on borders. Dominican Republic could also be affected by earthquakes, cyclones, landslides, drought, torrential debris flows, and others occurring in Haiti, and viceversa. Les menaces naturelles ne reconnaissent pas les frontières entre les pays. La République Dominicaine pourrait aussi se voir affectée par des des séismes, cyclones, inondations, sécheresses, torrents de débris et autres se matérialissant en Haïti, et viceversa.
