DESCRIPTION:Dr Natacha Tofield-Pasche\, Limnology Centre (LIMNC)\, EPFL\nA
 bstract:\nLake Kivu is an exceptional lake that contains enormous amount o
 f methane and carbon dioxidedissolved in the deep water. Evenif this gas a
 ccumulation could potentially lead to a limnic eruption\, methane extracti
 on could both reduce this risk and produce energy for the two riparian cou
 ntries. In Rwanda a pilot plant has extracted methanesince October 2008\, 
 generating 1.4 MW of electricity. Throughout this period\, the Lake Kivu M
 onitoring Program has assessed the potential impacts of this extraction an
 d established a baseline on Lake Kivu for future comparison. In this prese
 ntation\, I will give background information on the formation of methane i
 n Lake Kivu and how recent environmental changes might have affected the l
 ake. I will also explain the key findings from the monitoring of methane e
 xtraction.Dr. Natacha Tofield-Pasche is a limnologist with strong interest
 s in biogeochemical processes in lakes. Environmental Engineer from ENAC/E
 PFL\, she accomplished her PhD on nutrient cycling and methane production 
 in Lake Kivu in 2009. During the last four years\, she worked for the Gove
 rnment of Rwanda to develop the Lake Kivu Monitoring Program. Since 1st Se
 ptember 2013\, she is the coordinator of the Center of Limnology at EPFL.R
