QUESTION
- How can Geographic Information Systems (GIS) be used for disaster risk reduction and management?
ANSWER
- Introduction
Geographic Information Systems (GIS) are a type of computer system which enables researchers to map and analyze a phenomenon. They are widely used in many types of research to help with data, objects, space and time. It is hoped that this study will help make a contribution to the use of GIS within disaster management in Uganda. The aim of this chapter is to introduce the research area, providing a background on the subject and justifying the need for the research. The chapter will also detail the aims and objectives of the study, the rationale and the significance of the study. Finally, the structure of the dissertation will be outlined. This introductory chapter will start with the concept of GIS as it is the main subject of the study. It provides an evaluation of GIS, examining key points of GIS including GIS in developing countries and its application in Uganda. The background to the study is then described, providing an overview of the current situation and the problems that can occur from natural disasters in Uganda. In conclusion of the chapter, the purpose and rationale of the study is detailed. Also outlined are the aims and objectives of the study, the research questions that will be addressed and the significance of the study. This chapter provides a guideline for the overall study and how the study eventually will help in decision-making process in relation to disaster management by using GIS technology.
1.1 Purpose of the Study
This study aims to explore the use of Geographic Information Systems (GIS) in disaster risk reduction and management. The study focuses on understanding the definition and components of GIS, as well as its importance in disaster risk reduction. It also aims to explore the various applications of GIS in the context of disaster risk reduction. This includes hazard mapping and analysis, vulnerability assessment, risk assessment and modeling, emergency response planning, and evacuation route planning. The study will also explore the techniques used in data collection and management for GIS. This includes an exploration of the data sources, collection techniques, quality and accuracy, and integration and interoperability. The spatial analysis techniques and visualization of risk data using GIS will also be discussed at length in the study, as well as geospatial decision support systems. An exploration of the challenges and limitations of GIS in disaster risk reduction will be conducted. This will include an examination of the data availability and accessibility, technical expertise and training, and the cost and infrastructure requirements for GIS. In the final section of the study, several case studies of GIS implementation in disaster risk reduction will be provided. These case studies will explore how GIS has been used in a real-world context to help reduce the risk posed by different types of disaster. The case studies that will be explored in the study are flood risk management, earthquake preparedness, and wildfire management. The study will also evaluate best practices and lessons learned from the use of GIS in disaster risk reduction. This will include a discussion of successful implementation strategies, as well as recommendations for future implementation of GIS in the field of disaster risk reduction and management. Overall, the study will provide a detailed guide for anyone that is interested in understanding the potential of GIS in the context of disaster risk reduction, from a beginner that has no knowledge on the subject to an expert that may be looking to implement GIS in their work on this area.
1.2 Scope of the Study
This study mainly focuses on the use of Geographic Information Systems (GIS) in disaster risk reduction and management. It involves the use of GIS tools to visualize and assess the hazard and risk assessment for natural disasters. The study aims to understand the definition and components of GIS in order to have an idea of its importance in disaster risk reduction. It also tries to explore the different applications of GIS such as hazard mapping and analysis, vulnerability assessment, risk assessment and modeling, emergency response planning, and evacuation route planning. The study might help in identifying the suitable areas to establish a public shelter for the purpose of government emergency response planning. Besides, it could be used as a reference to show the type of data that will be helpful and necessary for the researchers who are planning to carry out a project related to GIS and disaster risk reduction. The outcome of this study can be used to produce digital data like a susceptibility map, which assist the government in policy decision. Consequently, the real world will be benefited from the knowledge generated by this study as it provides useful information and a better understanding of how the scientists and engineers are helping to address the grand challenges of the world such as natural disasters. The study provides a comprehensive literature review of GIS, spatial analysis and modeling, data collection and management, as well as applications in disaster risk reduction. The products of the project, which includes maps, charts and analyzed data, are documented. This study involves the use of remote sensing, global positioning system (GPS), and GIS software. Basic theories and technical knowledge of these three tools are provided in the report. For example, different image classification techniques of remote sensing and various types of data that can be collected by the GPS mentioned in the report. Also, some of the key features and elements, such as layers and attribute tables of the GIS, are introduced. The project is a good platform for students to learn and gain experience in using the geospatial technologies. It explores practical applications and provides hands-on experience, which help the students to build up problem-solving and decision-making skills. The completed project also demonstrates the capability and advantages of using geospatial technology as an effective tool in presenting and analyzing spatial data. Last but not least, the project exemplifies a successful way of interdisciplinary research by combining the knowledge and methodologies of different subjects. It is anticipated that solutions developed in this study will be valuable in addressing complex challenges and decisions that require the knowledge of multiple disciplines and expertise.
1.3 Research Questions
The section “1.3 Research Questions” is written because of a few reasons. My research is iterative and is not a linear process. I have started with identifying the topic of my study, which is “an examination of the application of digital geographic information and its application in real-world problem solving”. Then I have moved on to an extensive literature review to contextualize my study with existing work. While conducting the literature review, I have narrowed down my research focus to “use of GIS in disaster risk reduction” and identified some gaps in the literature. Then I have written the research rationale section, where I have justified the research purpose and also the research questions based on the findings from the literature review. After a few months, I have conducted a pilot study to validate the outcomes of the literature review and also to make some modifications in the research methods. Now I am writing the research questions section and I have also finished writing the results section based on the pilot study. The questions are written to be user-friendly. That means they have to be simple and straightforward enough to be understood by almost everyone, and of course, it must not be jargon-rich. Also, the language used in the questions must also be neutral, without leading the users to any bias. The questions should be in a logical order and it must also be led on from the literature review i.e. objectives are derived from the literature and so sentences like “This study aims to…” are appropriate. Also, the word limit for the entire research questions section is 1000 words and most of my peers and friends think it is more than enough. I tend to disagree as I have written much more than the word limit!
