While living in Paris in 2008, Sarah Toumi founded Dream, a networking scheme and incubator for environmental students.
[3] Toumi had been inspired after visiting Bir Salah where her grandfather lived, and seeing the difference over a prolonged period of time that desertification and a lack of water had on the surrounding land.
[5] Toumi adapted it to enable local farmers to use the acacias to generate an income source through selling the gum and the oil from drought-resistant moringa trees.
[2] The project has subsequently been called 1milliontrees4Tunisia, with Toumi becoming one of 30 winners of the Rolex Awards for Enterprise in 2016; the first time any Tunisian had won the prize.
[7] In October 2021, Sarah Toumi is developing a platform to digitize her model and thus improve the traceability of her projects in order to better be able to duplicate them.
