Interest in vertical farming is growing worldwide. This method of cultivation offers great advantages: local, fresh production that is possible at any location in a very sustainable way. On the negative side are the high electricity consumption and investment costs. Scientists from Wageningen University & Research, together with international colleagues, provide a balanced view of the current situation in a review article published in the renowned scientific journal Nature Food.
Vertical farming is an umbrella term for a method of growing in a variety of structures, such as empty buildings, specially constructed growth chambers or containers. The common characteristic is the closed nature of the system. This makes it possible to attune the conditions (light, climate, water, fertilizers) precisely to the needs of the crop. As a result, the crop grows evenly and can be planned. It is also possible to control the level of healthy nutrients in the crops.
"Vertical farming is still a specialized niche, but the potential is great. Interest is growing all over the world. Initially, there were some critical comments about its feasibility, but we have really moved beyond that phase. That is why we've honestly listed the pros and cons of vertical farming," says Sander van Delden, first author of the article in Nature Food.
The article was written at the journal's request. The Wageningen researchers involved many colleagues at home and abroad to produce a complete picture of all aspects of this growing method. This ranges from cultivation and technology to sustainability, health, social aspects and related policy.
