“…The interview excerpt suggests that the classist attraction to the island areas of Lagos are artificially created by the government through the concentration of urban development projects. These areas are expensive to live in and although wetlands and swamps surround the island, continuous development is taking place while increasing vulnerability to flooding for its inhabitants (see: Obiefuna et al, 2021). Based on data from Lagos State Government (LASG) (2013), Lagos Island's population is an estimated 2.4 million people while the mainland areas have an estimated population of 19 million people (see : Soyinka, 2018).…”

Urban coastal megacities like Lagos face flooding challenges that may be exacerbated by climate change in the future. Through an urban political ecology lens, this study engages with the dynamics of politics and power that produce differentiated flood impacts and adaptation strategies. Data from telephone interviews of 21 Lagos residents across the mainland and island areas reveal people's understanding of their flood vulnerabilities within the wider socio-political context of Lagos. In particular, state failure in the provisioning of services, amenities, and overall flood protection, shapes flood risk in Lagos. In addition, income and access to material resources inform people's experiences and ability to cope with flooding. Furthermore, citizens apply localized strategies to prepare for and cope with flooding events, particularly through Community Development Associations (CDAs). These localized strategies have implications for transformative resilience. However, these forms of endogenous resilience cannot replace attention to wider urban governance challenges in cities like Lagos.

“…To avoid rupture of the chamber (7) and to maintain the air inside the chamber, the pneumatic compressor has a pressure switch that stops the air supply when it reaches a maximum pressure inside the chamber (7). The valve (6) has been foreseen to be a two-way valve, so that it keeps the air inside the chamber (7) until the moment when the barrier (2) is to be collected, then changing its position, and releasing the air contained inside the chamber (7) to the atmosphere.…”

“…The devastating effects of Hurricane Katrina in New Orleans in 2005 and Hurricane Sandy in the New York metropolitan area in 2012 exemplified the extent to which today's cities are vulnerable and susceptible to losses due to natural catastrophes [3]. Within these meteorological phenomena and the damage produced against property and real estate are floods [4][5][6][7], which are feared for their significant consequences, including flooding inside homes and the enormous economic losses that this entails [8,9].…”

Increasingly, and with greater frequency, humanity is experiencing violent weather storms, which cause innumerable human and economic losses. Among the most frequent climatic storms that cause considerable losses are floods. Usually, domestic anti-flood systems are not autonomous; they require human intervention. This article presents Smart Flood Barrier (SFB), which is a fully automated system using sensors and composed of hinged lintels that can be installed on any door of any commercial brand. SFB is responsible for diverting the flow of fluid towards the center of a street with a certain slope, generating a “dry zone” near the entrance door to the house. This device also has a barrier installed in front of the door, which will be responsible for hermetically sealing the lintels, preventing the passage into the interior of the house if it is possible for the fluid to flow in the opposite direction to the direction of fluid flow.

“…The city of Lagos is bordered by several freshwater streams, a lagoon and the Atlantic Ocean. Its geographical location combined with its relatively flat topography and an average elevation of only 1.5 m above sea level (Ajibade and others, 2016) make this megacity vulnerable to coastal flooding, which will be exacerbated by the rising sea level (Odunuga and others, 2014;Obiefuna and others, 2021;Kaoje and Ishiaku, 2017). Sea level rise does show regional differences on Earth, and the coastline of Nigeria will see above average changes in sea level.…”

Lagos faces increasingly severe annual flooding, exacerbated by sea level rise and subsidence. In 2021, floods again submerged vehicles and houses, displacing thousands from their homes. The demand for sand in construction materials drives illegal sand mining and erosion on the coast of Nigeria, degrading ecosystems and increasing flood risk. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Lagos floods through a forensic analysis of academic literature, media articles and expert interviews.
