Mary Wanjiku Mwanza

Mary Wanjiku Mwanza is the Deputy Managing Director and co-founder of Palma Mukuyuni Tree Nursery, an agricultural enterprise and training centre in Makueni County, Kenya. She oversees the strategic direction, operational management, and community outreach initiatives of the nursery. She guides the company’s focus towards climate-smart tree farming, ensuring the production and distribution of high-quality fruit and timber seedlings to local farmers and cooperatives.

 

Before transitioning to the agricultural sector, Mwanza built a professional foundation in Nairobi, working within the corporate hotel and information technology industries. Seeking a more impactful rural livelihood, she relocated to Makueni County in 2014, officially establishing the nursery in 2016 alongside her husband. Under her leadership, the enterprise pivoted from cultivating a single timber species to developing a diverse, climate-resilient portfolio of fruit and indigenous trees, adapting to a region characterised by severe water scarcity and nutrient-poor soils.

 

Mwanza is a recognised authority in sustainable agriculture. She has been acknowledged as a champion farmer by the Australian Centre for International Agricultural Research and the Center for International Forestry Research and World Agroforestry for utilising fruit trees to bolster climate resilience in East Africa. Her expertise includes facilitating horticultural training and seedling health education for local farming communities, transforming small-scale farming into a commercially viable model.
