In his first major policy address on expectations for the World Summit on Sustainable Development to be held this August, United Nations Secretary-General Kofi Annan identified water and sanitation, energy, health, agriculture and biodiversity as five key areas where concrete results can and must be obtained. By concentrating on these five areas, the Secretary-General said, in a speech delivered by his wife Nane Annan at the American Museum of Natural History, the Summit could produce an ambitious but achievable programme of practical steps to improve the lives of all human beings while protecting the global environment.
