Landslide Susceptibility Maps

Landslides affect properties and the lives of a large number of people in many hilly parts of Vietnam and in the world. Damages caused by landslides can be reduced by understanding distribution, nature, mechanisms and causes of landslides with the help of model studies for better planning and risk management of the area. Development of landslide susceptibility maps is one of the main steps in landslide management. In this study, the main objective is to develop GIS based hybrid computational intelligence models to generate landslide susceptibility maps of the Da Lat province, which is one of the landslide prone regions of Vietnam. Novel hybrid models of alternating decision trees (ADT) with various ensemble methods, namely bagging, dagging, MultiBoostAB, and RealAdaBoost, were developed namely B-ADT, D-ADT, MBAB-ADT, RAB-ADT, respectively. Data of 72 past landslide events was used in conjunction with 11 landslide conditioning factors (curvature, distance from geological boundaries, elevation, land use, Normalized Difference Vegetation Index (NDVI), relief amplitude, stream density, slope, lithology, weathering crust and soil) in the development and validation of the models. Area under the receiver operating characteristic (ROC) curve (AUC), and several statistical measures were applied to validate these models. Results indicated that performance of all the models was good (AUC value greater than 0.8) but B-ADT model performed the best (AUC= 0.856). Landslide susceptibility maps generated using the proposed models would be helpful to decision makers in the risk management for land use planning and infrastructure development.

Involving citizens in river and flood risk management is critical for risk reduction and sustainable development within river basins, but local community input is often limited. This is partly due to the difficulty of quantifying the perceived values and risks related to the rivers, because these are based on personal knowledge and opinions. There is a need for more data on locals’ opinions and how they are spatially distributed across the river basin. Studies analyzing how perceived risks match evidence-based data can be a first step to including local knowledge in the decision-making process and pose the basis to enhance preparedness. Here, we present a blueprint questionnaire to characterize the perception of flood risk and its spatial distribution across the river basin. Respondents are asked their perception of the role of the river in terms of flood risk and management, as well as to pinpoint on a map the areas they identify as the most dangerous during floods. The approach is tested on the Tagliamento River in the Italian Alps, characterized by debates regarding flood protection, flood management and ecological conservation. The flood risk perception map shows good agreement between perceived risk and existing flood risk assessment maps in the lower basin, where major floods happened in recent memory (1966). In the upper basin, despite having suffered frequent floods, participants are more uncertain about the risks. There is interest in being involved in the risk management debate, and most respondents believe that risk reduction and river conservation are compatible. Land use planning is identified as a factor that can increase flood risk. The results point to the necessity to tackle together conservation, risk management and land use planning in order to develop risk-oriented river management strategies. Our study demonstrates how online participatory mapping can be used to improve the understanding of citizens’ perceptions and expectations with regards to their river, and support participation in sustainable river management.

This study examines how discriminatory land use planning predisposes the low income residents to flood disaster risks in Karonga town, Malawi. Using a qualitative research design, in-depth interviews were conducted with ten government and non government institutions engaged in land use planning and disaster risk management and traditional leaders. The study showed that theoretical aims of land use planning to improve the living environment remain partial and in certain cases exacerbate risks posed by floods because the planning tool divides the urban landscape into formal and informal spaces. Such separation which coincided with incomes levels forced the marginalised and urban poor to occupy flood-prone areas While literature on flood control promotes an integrated approach to flood risk management, land use planning practice is singled out as a regulatory measure which ironically not only fails to meet the needs, but also increases vulnerability to flood risks, of the urban poor residents. The study further revealed that land use planning has failed to reduce flood disaster risks in informal spaces because it is not compatible with the needs of the urban poor.

<p>Human activity is increasingly becoming a factor contributing to 'disasters' that occur worldwide. As evident in the Asian Tsunami of 2004, the high levels of loss of life and livelihood, and damage to property were largely due to the population density and human development of the physical landscape of the stricken region. The magnitude of natural hazards coupled with the high population density and low levels of development can have disastrous or catastrophic impacts on a nation as a whole, especially in small island states. Furthermore, the lack of governance structures, legislative compliance, and regulatory land use and planning coupled with the perception of risk of the general public, can all contribute to the magnitude of disasters. The flood plains of Navua, a small rural town outside of Fiji's capital and prone to all types of flooding, are explored to determine the extent to which human activities impact on the magnitude of flooding and flood damage. Human activities such as land degradation, deforestation of catchment areas, increased population density along the Navua riverbanks inadequate land use planning, zoning, and control of flood plain development; and inadequate drainage, and management of discharges are examined when determining the factors that have contributed to the increased incidence of flooding of the past 100 years until 2004. The evolution of different governmental approaches to hazard and risk management in Fiji is also explored. It is observed that while considerable progress has been made to address the factors causing high risk, there is still an emphasis on hazard mitigation rather than risk reduction. A model framework for flood risk management is referred to, where the elements at risk are the land-use characteristics of the Navua Catchment. As such, part of the treatment of risks is seen as requiring adequate risk management standards that fit into the broader 'all-hazards management' approach adopted by the Pacific Island Nations including Fiji.</p>

In land-use planning, taking natural hazards into account cannot be based uniquely on the degree of danger, as shown on natural hazards maps. The level of risk brought in by the different types of human activity in the areas exposed to these hazards must also be taken into consideration. The communes in canton Vaud will soon have completed the realisation of all gravitational natural hazards maps according to catchment area. Consequently, a cantonal and intercommunal strategy for integral risk management must be put in place. The implementation of this strategy requires some prerequisites such as: legislation based on risks, a definition of protection objectives, the organisation of a decision-making process involving all parties concerned, and which will make possible a comprehensive evaluation of land-use related interests. These reflections should result in a change of attitude when faced with the risks linked to natural hazards, and hence land-use adapted to these risks respecting the principles of precaution, equity and proportionality.

Risk Management Strategies

Abstract. The need for continuous adaptation to complex and unforeseen events requires enhancing the links between planning and preparedness phases to reduce future risks in the most efficient way. In this context, the legal-administrative and cultural context has to be taken into account. This is why four case study areas of the CHANGES1 project (Nehoiu Valley in Romania, Ubaye Valley in France, Val Canale in Italy, and Wieprzówka catchment in Poland) serve as examples to highlight currently implemented risk management strategies for land-use planning and emergency preparedness. The strategies described in this paper were identified by means of exploratory and informal interviews in each study site. Results reveal that a dearth or, in very few cases, a weak link exists between spatial planners and emergency managers. Management strategies could benefit from formally intensifying coordination and cooperation between emergency services and spatial planning authorities. Moreover, limited financial funds urge for a more efficient use of resources and better coordination towards long-term activities. The research indicates potential benefits to establishing or, in some cases, strengthening this link and provides suggestions for further development in the form of information and decision support systems as a key connection point. Aside from the existent information systems for emergency management, it was found that a common platform, which integrates involvement of these and other relevant actors could enhance this connection and address expressed stakeholder needs. 1 Marie Curie ITN CHANGES – Changing Hydro-meteorological Risks as Analyzed by a New Generation of European Scientists.
