Human mismanagement of environmental resources and processes significantly exacerbates the impacts resulting from disasters, and their effects on natural resources. Box 3.7 highlights some recent environmental disasters in Africa.

It has been estimated that, in the moist forests of Central Africa alone, as much as 1 million t of wildlife (primarily forest antelope, wild pigs and primates) may be killed for food each year. |
East Africa is exposed to seismic hazards due to the presence of the Rift Valley system. Earthquakes have been identified as a major threat in the area, which covers about 5.5 million km2 and holds more than 120 million people (Midzi and others, 1999). The vulnerability of East African populations to seismic events has been underscored by a recent study which advises that the region's capacity in earthquake preparedness and hazard mitigation needs to be improved 'significantly' (Midzi and others 1999).
In Central Africa, Mount Cameroon has erupted twice in the past 40 years, pouring out tonnes of lava and destroying farms and biodiversity. The last eruption was in the year 2000, and earth tremors occur every three to four years on average. Explosive emissions of toxic gases from Lake Nyos and Lake Mounoun, both crater lakes in the mountainous west of Cameroon, killed thousands of people, livestock and wildlife in 1986. Box 3.8 gives examples of disasters which have struck Nigeria in the recent past.

Although natural disasters cannot be prevented, sustainable utilization and management of the environment can increase coping capacities at community level. An effective management regime would include: economic policies which encourage smallholder agricultural production; the enforcement of relevant laws and regulations; incentive measures which encourage agricultural and biodiversity conservation at community level; and integrated and coordinated planning. The integration and implementation of sustainability strategies at community and national levels would enhance coping capacities by reducing dependency on aid. Sustainability strategies would develop and support an enabling environment for households and communities, and would improve forecasting abilities which could forestall the potential of environmental events to translate into environmental disasters.
