bookmark_borderSenegal Forecasts Climate Change Changes

Senegal is an African country on the west coast of the continent. The country is on the forefront of global warming’s impacts.

“Climate change makes life harder for Senegalese farmers in many different ways: shorter rainy seasons, more frequent and longer dry spells and droughts, a lower water table, floods, coastal erosion, destruction of mangroves, and disruption of fish stocks. But most pernicious of all is the salinization of soil across large tracts of coastal and riverine farmland,” reports the IRIN news agency.

Salinization is an example of a problem that is likely to effect many areas in the United States.

“For decades in Sine-Saloum, the soil, which used to be known for its quality and productivity, has been badly damaged by climate change, which has led to the salinization of the waterways of the delta,” explained Seydou Cissé, who works at Senegal’s National Institute of Pedology (the study of soils).

In an attempt to abate the problem, anti-salt dykes were built. They did help for a while; however, man’s plans do not compare to the force of nature. Already several islands along the Saint-Louis river have been washed away. “Three or four days after the rain, everything goes white. There are piles of salt. All the crops we sow die. All this is due to the salinity caused by the rising waters of the sea. And when we store valuables in our rooms, rust eats away little-by-little and eventually destroys them,” said Fatou Faye, a resident of Diamniadio island said in 2015. Since that time, the island has been washed away.

“When the sea enters in the river, because you have increasing of salt, it has killed many mangroves. And you know the mangroves are the nurseries of all the seafood,” said Aissata Dia of Actionaid Senegal.

“When the tide is high, the water goes into the kitchen and then gradually the water enters the rooms. My kitchen was rebuilt last year, but even today it is threatened by the rising waters. The high salinity of the seawater eventually breaks down even the cement. After three years, the building collapses,” said islander Faye.

In 2017, a sea wall built to help protect Senegal failed. The miles long breach is not repairable.

Reuters reported in May of 2017: “As Senegal’s coast crumbles, residents ponder move to safer ground”

“A French man told us once that there will be a time when this land won’t exist,” said Badiane, who lives in the working-class district of Guet Ndar. “Maybe in 30 years, maybe in 50. I don’t know.”

“(The people) are trying to fight, but in reality the phenomenon has become very serious,” said Abdou Sane, a former parliamentarian based in Dakar who has spearheaded efforts to reduce the threat of disasters. “It exceeds the means of the government, the means of communities,” he added.

Experts have urged the government to relocate other communities before they face a similar fate.

A UN-Habitat program in 2011 helped move about 60 families out of Guet Ndar to a settlement a short distance inland.

“That’s a way of being resilient,” said Mateugue Diack, a professor of agronomy and disaster risk reduction at the nearby Gaston Berger University.

But communication was lacking and people were reluctant to move, he said. The relocation effort fizzled out before it was completed.

Guet Ndar is populated primarily by fishermen whose families have lived there for generations. Most of those who have lost their homes have remained in the overcrowded area, squeezing in with relatives and neighbors.

“Unfortunately my country is one of those that has this huge problem. We always record that something may happen, that something has happened… but still do nothing,” said Diack.

San Diego County — As drinking water becomes scarcer, desalination will become a rising trend. California is experiencing an extended drought. San Diego County is building a $1 billion desalination plant.

Fresh drinking water will become a larger battle ground as it becomes shorter in supply. Global warming is causing contamination in large fresh water supplies. For example:
Flooding causes sewage treatment plants and other toxic spills to be dispersed.
Droughts cause an obvious shortage of water.
Rising sea water causes salinization. Salt destroys the soil and the drinking water.

San Diego has already seen the need for drinking water. “It was not an easy decision to build this plant,” said Mark Weston, chairman of the agency that supplies water to San Diego County. “But it is turning out to be a spectacular choice. What we thought was on the expensive side 10 years ago is now affordable.”

Since much of the world’s fresh water problems are becoming more severe due to global warming, it is ironic that the plant will use huge amounts of electricity adding to the problem. There is also concern over what the plant will do to sea life. What happens to plants and animals in the 50 million gallons of water a day? “Fish and other marine organisms are killed on the intake screens (impingement); organisms small enough to pass through, such as plankton, fish eggs, and larvae, are killed during processing of the salt water.” [Heather Cooley, Newsha Ajami, Matthew Heberger, The Pacific Institute December 11, 2013]

“Our position is that seawater desalination should be the option of last resort,” said Sean Bothwell, an attorney with the California Coastkeeper Alliance, an environmental coalition that has battled California’s turn toward the technology. “We need to fully use all the sustainable supplies that we have available to us first.”

As the sea level rises, more fresh water sources will become brackish at the same time as extreme weather events will cause extraordinary droughts. It’s a fresh water double whammy.
