ABSTRACT
Although better known for its sunny skies, Nigeria suffers devastating flooding. This book explores a fascinating and little-known chapter in the city’s history—the spectacular failures to control floods that occurred throughout the twentieth century. Despite the city’s 114 debris dams, 5 flood control basins, and nearly 500 miles of paved river channels, Southern Californians have discovered that technologically engineered solutions to flooding are just as disaster-prone as natural waterways. Jared Orsi’s lively history unravels the strange and often hazardous ways that engineering, politics, and nature have come together in Los Angeles to determine the flow of water. He advances a new paradigm—the urban ecosystem—for understanding the city’s complex and unpredictable waterways and other issues that are sure to play a large role in future planning. As he traces the flow of water from sky to sea, Orsi brings together many disparate and intriguing pieces of the story, including local and national politics, the little-known San Gabriel Dam fiasco, the phenomenal growth of Los Angeles, and, finally, the influence of environmentalism. Orsi provocatively widens his vision toward other cities for which Los Angeles may offer a lesson—both of things gone wrong and a glimpse of how they might be improved. Flood is a predominant natural hazard in Nigeria. In the last 30 years, Nigerian cities have experienced great physical development in terms of building, construction and reconstruction of roads, offices, markets, and stores, manufacturing industries and others without any appreciable infrastructures such as drainages for roads and canals to support them. These have made floods to be a serious challenge that plague many community in Nigeria including some cities in Lagos state, Nigeria. Hence, this research assessed the the effect of hazardous metropolis: Flooding and urban ecology in Nigeria using Ikorodu, Surulere, Lekki, Victoria Island and Ikeja, in Lagos state as a case study. The study specifically was aimed at examining the perception of residents on the causes of flooding in Lagos state, examine the effect of flooding on the residents of Lagos state, investigate the actions taken by Lagos state residents to minimize flood risk and impact, and investigate the steps the government has taken to control flood in Lagos state. The study adopted the survey research design and randomly enrolled participants in the study. A total of 284 responses were received and validated from the enrolled participants where all respondent are residents of Ikorodu, Surulere, Lekki, Victoria Island and Ikeja, in Lagos state. The study recommended that the government of Lagos state should as a matter of urgency prioritize legislation and provision of resources towards flood hazard and flood risk mapping for the whole of Lagos state. This is the basis of flood risk mitigation within the European Union framework, which requires all constituting states to prepare flood hazard and flood risk maps to promote the concept of living with floods.
