“…The rapid urbanization in Saudi Arabian cities has also led to an increase in natural hazards, such as increasing desertification and land degradation, water scarcity and habitat/species loss [68]. More recently, flash flooding hazards have become a serious issue and have caused human death and damages to urban infrastructure in most of Saudi Arabian cities [69,70]. Past land cover patterns and the direction of future changes suggest that urban growth will increase in the same areas, which may add more pressure to the sensitive environments in the five cities in Saudi Arabia.…”

Urban Land Cover Change Modelling Using Time-Series Satellite Images: A Case Study of Urban Growth in Five Cities of Saudi Arabia

This study analyses the expansion of urban growth and land cover changes in five Saudi Arabian cities (Riyadh, Jeddah, Makkah, Al-Taif and the Eastern Area) using Landsat images for the 1985, 1990, 2000, 2007 and 2014 time periods. The classification was carried out using object-based image analysis (OBIA) to create land cover maps. The classified images were used to predict the land cover changes and urban growth for 2024 and 2034. The simulation model integrated the Markov chain (MC) and Cellular Automata (CA) modelling methods and the simulated maps were compared and validated to the reference maps. The simulation results indicated high accuracy of the MC-CA integrated models. The total agreement between the simulated and the reference maps was >92% for all the simulation years. The results indicated that all five cities showed a massive urban growth between 1985 and 2014 and the predicted results showed that urban expansion is likely to continue going for 2024 and 2034 periods. The transition probabilities of land cover, such as vegetation and water, are most likely to be urban areas, first through conversion to bare soil and then to urban land use. Integrating of time-series satellite images and the MC-CA models provides a better understanding of the past, current and future patterns of land cover changes and urban growth in this region. Simulation of urban growth will help planners to develop sustainable expansion policies that may reduce the future environmental impacts.

“…Even though public awareness can help lessen the harmful effects of disasters, a prior study found that "cultural misconceptions and incorrect beliefs and attitudes" could cause inadequate public behavior in disaster preparedness and response [30]. Apart from educational institutions, informal education acquired at the family and community level is also valuable in encouraging an individual to act for reducing risks [22,50]. Also, identifying the most effective means of accessing disasterrelated information is important in communicating risk information among citizens and developing more adaptive and resilience schemes for disaster management involving educating the public.…”

“…Despite the existence of many seismic and volcanic areas, the country has only experienced low-magnitude earthquakes of not more than 4 on the Richter scale [18]. The most catastrophic disasters in the country are floods, sandstorms, and disease epidemics such as swine flu, severe acute respiratory syndrome, and Rift Valley fever [16,[20][21][22]. In 2009, swine flu affected 15850 people and caused 124 deaths throughout the country [20]; p. 12).…”

“…In Jeddah city, Al Saud [23] utilized satellite images and geographic information system to map zones susceptible to flood hazards and evaluate flood influencing factors: drainage systems, elevation, soil type, and human activities. In Riyadh city, Rahman et al [22] assessed public vulnerability to flash flooding. At the national-level, Alshehri et al [11] studied public perception and attitudes to disease epidemics [16].…”

A B S T R A C TDisaster risk reduction is an increasingly important policy issue, especially in developing countries that suffer most of the global human and economic losses associated with disasters. Indeed, public awareness and attitudes can help in disaster risk reduction and management efforts toward reducing mortality and economic losses. In Saudi Arabia, many cities have been recently experiencing incidences of disasters, such as floods, disease epidemics, and sandstorms. However, studies on public perception of disaster risk in the country are few and nascent. Therefore, based on a questionnaire survey (n ¼ 683), this paper explores public perception and attitudes to disaster risks in Dammam, a coastal metropolis in Saudi Arabia. The findings indicate that although almost two-thirds (64.7%) of the participants are aware of disasters, and 81% are concerned about disaster risks, less than half (47.3%) believe that their settlements could be at risk. While 37% opine that disasters are caused by both natural factors and human activities, about half (54%) indicate that they can personally contribute to reducing disaster risks. Chi-square analysis indicates a significant positive relationship between place of residence and perception of disaster risks (χ2 (6) ¼ 56.18, p < 0.05), and between place of residence and concern about disaster risks (χ2 (12) ¼ 68.47, p < 0.05). The paper recommends raising public awareness and encouraging positive behaviors in reducing disaster risks in the study area and similar environments.

Planning and Management Issues and Challenges of Flash Flooding Disasters in Saudi Arabia: The Case of Riyadh City

The paper sets out to unravel the issues and challenges in flash flood disaster management in Saudi Arabia, through Riyadh city as an example. The issue of flooding management and planning has been brought to the forefront of government agenda as a result of rising frequencies and intensities of flash floods in the country. It discussed specific issues, explaining what is lacking and what should be done to deal effectively should such an unfortunate event occur. The main challenging issues found are: 1) Disaster management in the Saudi context is still primarily a matter of response and relief operations as it does notinclude any proactive or preventive provisions against the devastating impacts of disasters; 2) Current management approach of disaster focusses predominantly on disaster containment rather than management;3) Local authorities do not have well-defined disaster management strategies supported by clearly defined action plans; and 4) Data and mapping technologies (e.g., GIS) are not a priority nor well appreciated as an effective decision tool in disaster management. Accordingly, the paper proposes adapting a comprehensive integrated management approach that adheres to the well-known four disaster management stages, and that ensures public participation, flexibility, transparency, production, accountability and effectiveness. It also proposes establishing well-equipped civil disaster and emergency management centres capable of collecting, storing and handling all the data about such events, hence facilitating analysis, modelling and disseminating information to all concerned parties. The local community should also be effectively involved in the whole management process.
