text: Policies and international agreements The export of hazardous waste to third world countries is another growing concern. Between 1989 and 1994, an estimated 2,611 metric tons of hazardous waste was exported from Organization for Economic Cooperation and Development (OECD) countries to non-OECD countries. Two international agreements were passed in response to the growing exportation of hazardous waste into their borders. The Organization of African Unity (OAU) was concerned that the Basel Convention adopted in March 1989 did not include a total ban on the trans-boundary movement on hazardous waste. In response to their concerns, on 30 January 1991, the Pan-African Conference on Environmental and Sustainable Development adopted the Bamako Convention banning the import of all hazardous waste into Africa and limiting their movement within the continent. In September 1995, the G-77 nations helped amend the Basel Convention to ban the export of all hazardous waste from industrial countries (mainly OECD countries and Lichtenstein) to other countries. A resolution was signed in 1988 by the OAU which declared toxic waste dumping to be a "crime against Africa and the African people". Soon after, the Economic Community of West African States (ECOWAS) passed a resolution that allowed for penalties, such as life imprisonment, to those who were caught dumping toxic wastes.
