Agriculture: soil-less farming, a solution for the future?

Soil-less agriculture, or hydroponics, involves growing food plants on agricultural, agro-industrial and even landfill waste substrates. It is mainly developed in greenhouses or closed, controlled environments. This type of agriculture responds to the constraints of land scarcity and soil erosion, can be adapted to all essential crops and helps to combat deforestation. In Grand-Bassam in Côte d'Ivoire, a group of enthusiasts have taken up the subject of soil-less planting and adapted it to the production of Big Sun, the famous "good-smelling pepper ".
