Floods in Douala, Cameron, affects about 30,000 persons

DOUALA, 1 July 2015 (IRIN) – More than a week after floods caused by heavy rain in Cameroon’s economic capital, Douala, killed at least four people and destroyed the homes and businesses of thousands of others, displacing at least 2,000 people and directly affecting more than 30,000, the city remains devastated.

Fallen electric poles are a grim reminder that much of the city is still without power, upturned wrecked cars and motorcycles lie abandoned in gutters, trash and other debris litter the muddy streets.

The Ministry of Homes and Urban Development and the Urban Community Delegation of Douala says “millions of dollars” of damage have been caused.

“Our whole life is now shattered,” said 39-year old nurse Arlette Mbappe.

“I have no home. It’s up to me to repair the damage of what remains, but even finding food for my children has become difficult.  I would look for other accommodation, but that has become very difficult to find.”

Tropical monsoon rains and subsequent flooding are becoming more frequent in southwestern Cameroon, as well as in other countries with shores on the Gulf of Guinea. Each year the heavy rains seem to become more deadly and do more damage.

“The floods, like those that are shaking our city, are becoming more common in light of global warming, and as other factors, such as urbanization and agricultural practices, are taken into account,” said Philippe Edimo, an urban planning engineer who works for the National Meteorological Directorate in Douala.

Annual rainfall fluctuates from year to year, but in Douala, for example, averaged 3,000mm of rain per year between 1906 and 1965. This has since increased to 3,200mm in 1989 and 3,800 mm in 2010, before falling to 3,080mm in 2014, according to the National Department of Meteorology (DMN).

Between 1998 and 2006, 4,200 people were affected by flooding in Cameroon, according to data from the Centre for Research on the Epidemiology of Disasters’ Emergency Events Database (EM-DAT). In 2007, more than 10,000 people were affected in a single year. In 2008, 25,000 and in 2012, nearly 52,000.

Urban planning

Experts attribute this surge to a construction boom and urban population growth in coastal areas.

“Rapid urbanization coupled with inadequate city policies has contributed to the strengthening of a number of socio-economic and environmental imbalances,” Edimo told IRIN. “And it is likely that higher temperatures that are affecting the region will only intensify the hydrological [rain] cycle, leading to more major and recurrent floods.”

The results of national climate simulations show that the average annual rainfall in Cameroon could increase by as much as 35 percent between 2010 and 2050, and temperatures could go up by at least two degrees Celsius.

Despite warnings by authorities and a 2004 town planning law that prohibits construction on lands “unsuitable for habitation,” many buildings in Douala are still built in flood zones.

“People build buildings in risk areas because of their prime locations,” said Christophe Edzimbi, who works for Cameroon’s National Geographic Centre in Yaounde.

He added that deforestation and the dredging of sediment from coastal areas also contribute to flooding.
