Urban Development Dynamics and Flood Risk Assessment in Gombe Metropolis, Nigeria | Chapter 3| Current Research on Geography, Earth Science and Environment Vol. 4

 

The worldwide population is fast urbanising, with towns undergoing extraordinary growth. Gombe Metropolis, one of Nigeria’s major urban centres, has been meaningly affected by the adverse impacts of persistent annual flooding, leading to prevalent environmental issues and damage to urban societies. Rapid urban development in the city, motivated by the conversion of vegetated areas, open spaces, farmlands, and bare lands into built-up environments, has increased the city’s annual flood risk. Notwithstanding numerous interventions by the government, communities and private efforts to control and mitigate the urban flooding have not been effective. Hence, this study examines the urban development variables contributing to the growing flood risk and frequency in Gombe Metropolis. Data were basically collected through field surveys, including questionnaire administration, and analysed using correlation and regression techniques. Spearman’s Correlation and Multiple Linear Regression models were used to establish statistical relationships between flood risk and independent variables of the urban development, and these include social vulnerability, geographical characteristics, and urban development factors. The findings expose that rapid and unplanned urban development dynamics are the prime drivers of cyclical flooding and the heightened flood risk in Gombe Metropolis. Significant factors prompting flood occurrence include inadequate flood control measures, insufficient and poor drainage systems, failure to obtain building plan approvals, substandard housing structures, and poor solid waste management practices.

Promoting Public Participation in Environmental Protection and Flood Risk Management in Ho Chi Minh City – Vietnam | Chapter 7 | Insights into Economics and Management Vol. 11

 Flooding in cities is becoming a more serious problem. It has been a common occurrence in many towns and cities around the world in recent years. Flooding in Ho Chi Minh City's metropolitan regions offers major issues, not only because it affects a huge number of people and properties, but also because it directly impedes the city's economic progress. Despite a massive technological effort to upgrade the city's drainage system, which is necessary by the city's unprecedented growth as well as the issues of climate change and ground subsidence, flooding will continue. The human factor appears to be a significant influence in the flooding problem and flood-reduction initiatives. The focus of this study was on the issue of improper waste disposal, which causes drainage systems to become clogged. An interactive survey was done in roughly 820 households in flood-prone areas as part of a well-planned campaign. The poll focused on public waste disposal awareness and behaviour among flood-affected families. People who have a good awareness of the causes of floods and a sense of environmental conservation can help reduce floods. Community awareness, management, and sanctioning solutions, in addition to technological solutions, are required.
