How it all began

The idea for Osotua Foundation started in 2012. Founder Dieke Geerling lived among the Maasai in Loita Plains for almost two months. Experiencing the deterioration of the savannah ecosystem, she had many talks and discussions with Maasai how to turn the decline into a positive and healthy sustainable future combining traditional knowledge with modern science.


These talks and sharing ideas lead to collaboration with Nkoilale Community Development Organisation and later on with more Maasai communites. Together a sustainable ecosystem regenaration vision for the savannah to survive climate change is developed.

The Osotua Foundation combines Dieke's ideas, experiences and knowledge which she accumaulated while living and working in the savannas ofAfrica for a greater part of her life. Her passion for this ecosystem urges her to support its inhabitants in making it future-proof. She believes that Ecology, Economics and Anthropology are essential components in achieving this goal holistically. With the help of many Maasai and her board members and adivsors she is making this dream a reality!
