 Nairobi has a history of being an urban center interwoven with ecology with natural forests, savanna grasslands and three major rivers running through it. However the urban expansion of the city along with a growing population has led to significant loss in tree cover, increased waste mismanagement and water degradation. Some of the startups found in Nairobi in the business of regeneration include Shamba Network, repsentatives of Regen Foundation, Celo, and Open Forest Protocol among others.
