Abstract

This article examines the effects of the recent climatic changes being experienced as flooding in some parts of Lagos State and its environs in Southern Nigeria. Lagos State is one of the world’s most densely populated cities with a population of about 20 million people, half of which are considered to be in abject poverty. The state is recognized as being vulnerable to climate change because of its topographical situation (coastlands and wetlands) and demographics. The climatic variations has caused the rainfall regimes and patterns to be altered, causing widespread flooding which has not only led to the loss of life and properties but has also impacted negatively on the social and economic activities in the state, substantial modification of ecosystems, and general discomfort to the populace. This situation is further compounded by excessive waste generation and indiscriminate refuse disposal due to over population. Information is provided on flood management and mitigation strategies peculiar to the state. Of interest in particular, is the introduction of a proactive integrated approach for flood management. Finally, the paper provides a good reference material and guide for further studies in water-related disaster management both at the local and international levels. Keywords: flood, Lagos, climate change, rainfall, mitigation strategies, flood management, global warming, vulnerability map, Southern Nigeria, risk reduction.
