About the job
Who We Are
At Trees for the Future (TREES), we believe farmers have the power to transform the world. For over 30 years, we have been a global leader in agroforestry training, partnering with farming families to build vibrant economies, sustainable food systems, and thriving ecosystems. Through our signature Forest Garden Approach—a proven nature-based solution—farmers restore their land, plant thousands of trees, and grow diverse crops, breaking cycles of climate change and generational poverty. By reclaiming their agency, farmers are creating new possibilities for their families, communities, and the environment. Active in Kenya, Mali, Senegal, Tanzania, and Uganda, TREES has planted over 350 million trees to date. Joining our passionate, collaborative team means empowering farmers to lead lasting change for people and the planet.
TREES embarked on its mission in Tanzania in 2015, strategically focusing on five pivotal regions across the mainland: Mwanza, Simiyu, Singida, Tabora, and Iringa. Throughout this journey, we have collaborated with farmers across 11 District Councils, empowering them with the resources and knowledge necessary for sustainable environmental and agricultural practices. Through these efforts, we significantly contribute to sustainable food security, environmental conservation, thriving ecosystems, and the reduction of poverty at the household level. By adopting the Forest Garden Approach, farmers are leading the charge for sustainable development and creating brighter futures for their communities.
