It's harvest season for farmers in Tunisia. Here workers collect olives at an organic grove in Oudhna, near Tunis.
Out of 250 categories of organic products grown in Tunisia, around 60 are exported.
Despite its small size, Tunisia ranks 30th in the world and first in Africa in terms of area certified for organic farming.
Tunisian farmer Sarah Shili says going organic is 'the future of farming' - and as demand surges in North Africa and beyond, the sector is blooming.
Ms Shili owns a farm near Tunis that produces organic-certified vegetables, fruit and cereal crops in a way that 'respects nature'.
The farm's revenues have surged thanks to strong demand and the growth of online sales, multiplying five times in as many years to hit 100,000 euros in 2020.
