The world's remaining indigenous peoples - estimated at over 250 million people in 70 countries - possess sophisticated knowledge that could yield solutions to successful management and development of the land not only in their regions but elsewhere as well. This paper reports on four such groups: the Quichua of eastern Ecuador, the Masai and the Sumburu of Kenya, and the tribal peoples of the Philippines. It is clear that indigenous people want to play a part in the future of their lands and this report concludes that it is in all our interests to include them in debates about development and the environment.
