Available in PDF, EPUB and Kindle. Book excerpt: East Africa encompasses numerous developing countries and involves one of the most active continental rifts on Earth; namely, the East African Rift System. This region is prone to diverse geohazards due to its geographical location at the plate boundary. Several damaging events had happened across the region and more are predicted to occur in the near future. Therefore, it is crucial to investigate, assess, and forecast natural hazards and potential risks in the region. In this dissertation, remote sensing and Geographic Information System (GIS) were employed to conduct three independent studies focused on assessing geohazards in east Africa. Each study is presented in a paper format in a separate chapter in this dissertation as the papers are either published or being considered for publication in peer-reviewed journals. The first study addressed desegregation of remote sensing and GIS to characterize fluctuations in the surface water area of the Afar lakes in Ethiopia during 1998-2016. Landsat 5, 7, and 8 images were processed using a GIS density slice technique to reclassify the near infrared bands. A time series of surface water area changes for eight lakes was created to examine why these changes have occurred and to determine the main factors that have controlled lake fluctuations over the years. The second study has been focused on a hazard assessment for the Grand Ethiopian Renaissance Dam (GERD). The dam is constructed in northwest Ethiopia across the Blue Nile and has created a geopolitical dispute between the upstream country (Ethiopia) and the downstream countries (Sudan and Egypt). The downstream countries are concerned about the dam's safety and its anticipated potential negative impacts on their agricultural activities, environments, and residents. In this study, a weighted GIS model was created to assess hazards at GERD and its surroundings. Nine factors, including earthquakes, volcanoes, faults, fractures, lithology, slope, soil, and precipitation, as well as depth to the groundwater table, were considered and weighted via the Analytical Hierarchy Process. Then, a weighted overlay was established to evaluate local hazards in the study area. The third study has been dedicated for assessing landslide susceptibility in Kenya. Southwest Kenya is naturally prone to landslides and has experienced recent landslide events that killed people and damaged its infrastructure and environment. About 130 historical landslide events were used to determine the main factors influencing landslide occurrence in Kenya. Factors such as precipitation, lithology, slope, elevation, soil, land-cover, faults, earthquake events, and streams, and roads were determined. Weighted overlay and fuzzy logic models were then created to produce landslide susceptibility indices for Kenya. The three aforementioned studies have provided crucial details and unprecedented results that are necessary for the decision makers to mitigate the impact of inevitable geohazards in east Africa. This research project suffered from the scarcity of geospatial data and relevant publications over the selected study areas. I hope that my peer-reviewed publications and research outcomes will fill in this gap, will raise awareness in the encountered developing countries, and will support future research with precious datasets.

This book was released on 2000-08-29 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global problems require global information, which satellites can now provide. With ever more sophisticated control methods being developed for infectious diseases, our ability to map spatial and temporal variation in risk is more important than ever. Only then may we plan control campaigns and deliver novel interventions and remedies where the need is greatest, and sustainable success is most likely. This book presents a comprehensive guide to using the very latest methods of surveillance from satellites, including analysing spatial data within geographical information systems, interpreting complex biological patterns, and predicting risk both today and as it may change in the future. Of all infectious disease systems, those that involve free-living invertebrate vectors or intermediate hosts are most susceptible to changing environmental conditions, and have hitherto received most attention from the marriage of analytical biology with this new space technology. Accordingly, this volume presents detailed case studies on malaria, African trypanosomiasis (sleeping sickness), tick-borne infections and helminths (worms). For those who are unfamiliar with this science, and unsure how to start, the book ends with a chapter of practical advice on where to seek hands-on instruction. The lessons to be learned from these studies are applicable to many other epidemiological and ecological problems that face us today, most significantly the preservation of the world's biodiversity. Only book to provide a synthesis of complex biology, quantitative analysis, space technology and practical applications, focused on solving real epidemiological problems on a global scale Broad scope, with methods relevant to subjects ranging from biodiversity to public health Practical advice on relevant courses 24 pages of colour plates

Available in PDF, EPUB and Kindle. Book excerpt: "The success of natural disaster study depends on updated, accurate, and exact information. This information should be collected and arranged logically to enable appropriate authorities of all levels, such as state officials and urban planners, to address crises before, during, and after the event. Modern technologies, including remote sensing methods and geographic information systems, enable the collection of information that satisfies the requirements of natural disaster studies. Computer systems provide for the collecting, saving, retrieving, processing, and analyzing of data, and can produce visual outputs such as tables and graphs. Such systems also give authorities access to information like routes to damaged areas, health care stations, police, firefighters, auxiliary forces, possible landing spots for helicopters and airplanes, places for reserving food and rescue devices, and urban infrastructure as well as addresses, phone numbers, and email addresses of residents or communication facilities. Remote sensing and geographic information system development can integrate all this information by organizing it into layers and creating maps in both digital and physical formats. Data represented by geographic information systems are linked to geographical coordinate systems, enabling ease of access. Such resources are critical for analyzing, comparing, and fully understanding crises. The archival of previously processed information opens opportunities for decision makers to solve problems more effectively. These are the main concepts explored in this book"--

This book was released on 2011-12 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: An urban hazard is a potentially damaging phenomenon that threatens a city, its population and related socioeconomic activities. There is not only a single hazard, but many hazards to which a city is vulnerable, though the probability of occurrences and intensity may differ from hazard to hazard. The book tries to address the recurrent geo-hazards in a typical hill town using Remote Sensing and Geographic Information System techniques. It also tries to see how a rapid pre-damage assessment can be carried out in a situation with scarcity of spatial data within a short period of time, by integrating available data with historical data on occurrences of natural disasters. The case study was conducted in a part of Kohima Town, Nagaland, in the North-Eastern parts of India, which lies in the zone V of the seismic map of India. Three hazards namely: seismic, landslide and fire were taken for analysis and an estimation of buildings that may suffer damage during an earthquake, landslide and fire were carried out.

Download or read book Hydrogeological Hazard Susceptibility and Community Risk Perception in Rwanda written by Lanhai Li and published by Springer Nature. This book was released on 2023-06-21 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book employs qualitative and quantitative methods to assess and scrutinize the impacts of climatic, topographic, land use, hydrologic and geologic factors on the hydrogeological disasters particularly flood and landslide in Rwanda. The hydrogeological hazard susceptibility and its spatial distribution is also mapped by integrating geospatial techniques and mathematical modeling approach through remote sensing and Geographical Information System (GIS). On the other hand, questionnaires and interview are used to evaluate the community's perception on the risk of hazards. The results unveiled different zones most susceptible to the incidence of both hazards as well as their main contributing factors. Furthermore, the results revealed that the government is perceived as responsible for all mitigation measures instead of being a shared responsibility, a perception that may also contribute to the increase in susceptibility. Therefore, it is necessary to deliver the extent of disaster-related courses and trainings in both schools (from primary to tertiary level) and local community members, which helps improving the public's awareness, understanding and ability by providing a new perspective toward disaster prevention and reduction. The book provides a reference for interested readers to understand the natural and human geography of Rwanda, the distribution of hydrogeological disasters, and the policy-making of disaster prevention and reduction.
