13 November 2017, Cairo, Egypt - An employee harvesting olive trees at the farm of Faris Farrag, founder of the first Egyptian aquaponics farm, during the visit at his farm of an FAO team and farmers from Egypt, Algeria and Oman, part of the program of Farmer-to-farmer study trips. The main objective of these farmer-to-farmer study trips is to promote and develop national potential on effective sustainable non-conventional water use practices for integrated agriculture-aquaculture production systems through the exchange of knowledge, experiences and expertise among farmers from the three studied countries (Algeria, Egypt and Oman). In this aquaponics farm high-end produce is cultivated with minimal and clean water consumption. Long hydroponic beds holding different varieties of organic lettuce, herbs, and vines, are connected to four massive fish tanks with about 1000 tilapia fish. The fish tanks provide 90 percent of the nutrients plants need to grow.,13 November 2017, Cairo, Egypt - An employee harvesting olive trees at the farm of Faris Farrag, founder of the first Egyptian aquaponics farm, during the visit at his farm of an FAO team and farmers from Egypt, Algeria and Oman, part of the program of Farmer-to-farmer study trips.
