Lake Kivu, freshwater lake system bordering Rwanda and the Republic of Congo, may soon have dire consequences for those living along its banks. Scientists have expressed their fears that the lake runs the risk of turning into a freshwater time bomb because of a dangerous level of carbon dioxide and methane gas.
In a region prone to volcanic and seismic activity, the fragility of Lake Kivu is a serious matter.
Compounding the precarious situation is the presence of approximately 2 million people, many of them refugees, living along the north end of the lake.
An international group of researchers will meet January 13-15 at a conference in Gisenyi, Rwanda, to grapple with the problem of Lake Kivu.
"Most scientists are fairly in agreement that the lake is pretty stable; it's not as if it's going to come bursting out tomorrow," said Anthony Vodacek, conference organizer and associate professor at RIT's Chester F. Carlson Center for Imaging Science.
"But in such a tectonically and volcanically active area, you can't tell what's going to happen," he added.
One of the problems with Lake Kivu is that the 1,600-foot deep lake never breathes.
The tropical climate helps stagnate the layers of the lake, which never mix or turn over. In contrast, fluctuating temperatures in colder climates help circulate lake water and prevent gas build up.
