Sediment Disaster

Taitung County with the total area of 3,515.24 km2lies in the eastern Taiwan. The topography of hillslopes at Taitung County is quite steep combined with fragile geological structure. After Typhoon Morakot, Taimali watershed located at the southern part of Taitung County was selected as major study area. The mechanism, behavior, and scale of sediment disasters are analyzed to rule out their interaction of the factors regarding to the debris flow occurrence in Taitung area. In this study, 522 disaster prevention engineering sites were investigated from the field and analyzed by using the Multiple Linear Regression Analysis. Finally, GPS/GIS/RS integrated with the digital terrain data was used to establish risk assessment model which can be utilized as an indication of sediment disasters occurred at Taimali watershed attacked by Typhoon Morakot in 2009. The accuracy of this model estimation is more than 80%. All results established by this study can help Taitung Country set up its own disaster prevention system and keep well development of rural and city in the eastern Taiwan.

Socioeconomic Vulnerability

The objective of the research is to expose the socioeconomic impacts in Tlacotalpan, Veracruz, considering a sudden increase in sea level of 5 meters. The interdisciplinary methodology consisted of locating, territorially quantifying the vulnerable groups that are currently within the danger zone and the second consisted of qual-ifying, through fieldwork, the specificities of the same. the most pressing results were: the municipality of Tla-cotalpan suffered a flood of five meters above sea level, 23% of its territory would be flooded, that is, 133 km2 of its demarcation present a certain degree of socioeconomic vulnerability to sea level rise. With the above, it is necessary to carry out the disaster prevention policy aimed at vulnerable groups. Keywords: Coastal geography, sociocultural vulnerability, economic impact.

Aims: The aim of this research was to assess the knowledge, perceptions and attitudes of victims and stakeholders on environmental disasters occurring in Businga territory. Study Design: This research employed a descriptive study design whereby the characteristics of respondents were described. Place and Duration of Study: The study was carried out in Bodangabo, Businga and Karawa sectors of Businga territory in Nord-Ubangi, Democratic Republic of the Congo between January 2016 and December 2017. Methodology: A survey was conducted on 150 respondents among the victims and stakeholders in the prevention and management of environmental disasters in three sectors of Businga territory to whom the semi-structured questionnaire was administered. Results: The findings show that 54% of environmental disasters originate from bushfire and 46% from floods. The bushfire is more evident in the area of Bodangabo and Karawa, while the flood is noticed in the area of Businga precisely in the city, because the ¾ is largely crossed by streams (Likpolo, Lokame, Legbala, Mongala). Thus, 80% of disaster victims are not satisfied with the support. However, 96% of respondents denied the provincial government's contribution, 92% confirmed the total absence of the environmental disaster prevention policy, and 88% confirmed the inefficiency of disaster prevention mode in Businga territory. With regard to the period of onset of disasters, it is clear from this survey that the floods are sporadic and occurring every two or three years compared to the bushfire which is manifested every year. 68% of the difficulties are due to lack of awareness due to insufficient financial resources and 32% to the shortage of qualified personnel for the prevention and management of these disasters. Conclusion: The lack of a policy of prevention and management of environmental disasters both at the provincial and local levels is at the base of this high frequency. Therefore, it is relevant that a provincial body responsible for alerting and advocating to the stakeholders involved in the prevention and management of environmental disasters, to settle in all Businga sectors. Furthermore, it is necessary to install the early warning system as tool of disaster prevention.
