Is this the end of vertical farming? 垂直農(nóng)業(yè)是否已走到盡頭？
與傳統(tǒng)的室外農(nóng)耕相比，垂直農(nóng)業(yè)用地面積相對少得多，因此它最初被視為一種節(jié)省空間的創(chuàng)新種植方式。雖然人們曾認為這個種植方式前景大好，但如今它正面臨威脅。垂直農(nóng)場上的作物是在沒有陽光的受控環(huán)境下、依靠LED燈光生長的，因此從一定程度上看，能源成本的上升導致了垂直農(nóng)業(yè)的現(xiàn)狀不容樂觀。垂直農(nóng)業(yè)是否已經(jīng)走到了盡頭？本期節(jié)目圍繞這個話題展開討論。
詞匯：farming 農(nóng)耕
Why do farmers grow crops outside in fields when we can stack them vertically? The idea of vertical farming was first proposed in 1999. It was seen as a way to save space, reduce air miles and transform old and abandoned buildings, like warehouses. In 2021, Fortune Business Insights valued the global vertical farming market at 3.47 billion dollars. Now, however, this industry is under threat, partly due to rising energy costs.
According to the magazine Science Focus, vertical farming gives ten times the yield of conventional outdoor farming. However, in order for crops to grow using this method, plants are placed in a controlled environment, grown not under the Sun, but under LED lights and watered with recycled water pumped on a closed-loop system.
Unfortunately, energy prices have risen across the globe. Therefore, this reliance on electricity has meant the last few years have not been easy for the industry. Cindy van Rijswick, from the Dutch research firm RaboResearch, has estimated that operational costs for a vertical farm are around 15% higher now compared to 18 months ago. Infarm, Europe's largest vertical farming company, made around 500 employees redundant back in November 2022 because they needed to downsize. They blamed higher operating costs due to energy increases as one reason for the layoffs.
Another issue related to the cost-of-living crisis and affecting vertical farming is the type of produce grown. This includes herbs such as basil, as well as salad leaves and leafy greens. Compared to traditionally farmed ingredients, like onions and carrots, these products are more expensive so could be less in demand as consumers watch their spending more.
So, it seems a future with food grown under LED lights is looking less and less bright.
