About us

Mama Tierra is a Swiss non-profit organization supporting indigenous peoples since 2015. Human rights activists founded the association to drive social change and gender equality for indigenous women in Colombia and Venezuela, while protecting Mother Earth.

Mama Tierra puts a special focus on indigenous women as they earn the family’s living, bring up the children and pass on the indigenous heritage. That is why we created the Mama Tierra accessory brand in collaboration with indigenous women who craft our products with great dedication.

We believe that sustainable fashion and development is best executed through a non-profit structure. Because being legally binding to pursue social causes is a warranty that sustainability in fashion really happens. On the other hand, as non-profit we stand for the “trade not aid”-philosophy. Firstly, not relying solely on donations to develop social projects. Secondly, empowering beneficiaries with jobs and opportunities, rather than imposing social programs on them that might not be accepted in their culture or might not work in their environment.
