A picture taken on January 11, 2021 shows oyster mushrooms growing in a humid basement at the Al-Amal farm, which was established by a group of young Syrian activists displaced from the Ghouta region near Damascus, in Afrin in Syria's rebel-held northern Aleppo province. - The group of self-taught young Syrians had gained experience during the five-year siege of the Ghouta region by regime forces, between 2013 and 2018, when they started producing mushrooms in small quantities to cope with the limited food supply and to replace meat. Now in their new workshop in the humid basement of a building in the city of Afrin, near the border with Turkey, they say they produce around 300 kilograms of mushrooms per week for sale in Aleppo and Idlib markets at the rate of 1.35 US dollars per kg.
