The globe witnessed an escalation of natural disasters in the later part of the 20th Century and the early 21st century with the period between 1990 and 2005 alone accounting for more than half of the total recorded natural disasters, leaving behind strong negative impacts especially in developing countries. Cameroon’s geological setting and tectonic history makes her one of the worst countries affected by rapid onset natural disasters in Africa.

A natural gas explosion from Lake Nyos in the northwest of Cameroon in 1986, killed over 1,700 inhabitants and almost all livestock in a diameter of over 25 kilometers around the lake. Investigations on Lake Nyos after the disaster discovered huge amounts of carbon dioxide (300 million cubic meters) that is being added in such a rate that saturation could be reached within years in the deeper layers of the lake. Since it is impossible to guarantee the perennial stability of the lake, survivors were resettled in seven camps and the Government of Cameroon, with foreign partners, embarked on a degassing project in 1995 with one full-fledged degassing pipe installed in 2001. Fresh scientific evidence on Lake Nyos concludes that another disaster is possible within the next five to ten years. This would inflict severe damage on the livelihoods of an estimated population of over 10.000 in the villages around Lake Nyos and in neighboring Nigeria.

This research aims at

  1. analyzing the livelihoods of households around Lake Nyos
  2. assessing social risk management strategies and vulnerability to natural disasters, and
  3. understanding and making policy recommendations on the role of social networks as one possible social risk management instrument.

A standardized questionnaire will be used to randomly collect cross sectional data for 400 households from five camps and three villages, supplemented with qualitative methods. This will be compared with a matching sample of 150 households. The Principal Component Analysis will be used to analyze household poverty and vulnerability indices, while network analysis will facilitate a quantification of social networks and possible implications in a comprehensive social risk management strategy. This will contribute scientific knowledge on social risk management of disasters and valuable instruments for policy implementation.
