Nigeria: Why Cities in Nigeria Are Prone to Flooding – Experts
Lack of proper urban planning has been blamed for the reoccurring cases of flooding in most cities across Nigeria.
Prof. Ibrahim Yari Mallo of the University of Abuja stated this in a lead presentation at a one-day workshop with the theme: ‘Blue-Green Initiative for Urban Flood Resilience in Nigeria’, organised by the University of Nottingham in collaboration with the Agricultural Research Council of Nigeria, in Abuja on Wednesday.
Prof. Mallo held that most cities in Nigeria were not carefully planned with homes and offices constructed with disregard for nature and the future, pointing out that the problem of flooding also increased by the way buildings are constructed in the country.
According to him, “The most common environmental problems in Nigerian urban centres are flood. The singular reason to this is that most Nigerians hardly link the generation of flood to the corrugated iron sheet rooftops they use in roofing their houses. People who have the money also concretized their surroundings forgetting that water has to infiltrate into the ground as a natural process…READ ON
Paris increasingly threatened by heatwaves, floods
The French capital is at risk of recurrent heatwaves and more frequent flooding because of climate change, according to a study conducted for the Paris City Hall.
In the years to come, “the volume of rainfall should increase slightly and the number of rainy days should decrease, with an increase in rainfall and, therefore, greater risks of flooding,” the City Hall explained in its report on Paris and climate change released on Wednesday.
Global warming in Paris, where the temperature have already risen by 2.3°C compared to the pre-industrial era, is increasing the risk of ten-year floods by 20% and the risk of one hundred-year floods by 40%.
Risk of pollution
A major flooding episode in the Paris region “would be likely to destroy or disrupt certain vulnerable infrastructure” and would threaten water quality, with a signifcant risk of pollution for 1.3 million subscribers in habitants from over burdened infrastructure like the sewage network, with 20% of the treatment plants located in flood-prone areas…READ ON
