Hedging against climate uncertainty with controlled food growth

Last year, social distancing restrictions and border closures created harvest and supply chain issues for growers. While we all expected this year to be better, 2021 has begun with continued Covid-19 restrictions. At the same time, wildly unpredictable global weather has wreaked havoc on food production and distribution. In this article, Heliospectra talks about hedging against climate uncertainty.

Europe’s uncommonly harsh weather not only caused fruit and vegetable shortfalls in the Southwest, but snow and rain disrupted transportation routes northward. The Netherlands, parts of the UK, and Northern Germany faced cold and more snow than they had seen in at least a decade, thanks to storm Darcy, which interrupted transport into those regions. Meanwhile, Southeastern Europe and Turkey were experiencing higher than usual temperatures and droughts.

What does all of this mean to the food supply? Global warming and climate uncertainty are making traditional farming increasingly unpredictable. But there is a solution – hedging against climate uncertainty with Controlled Environment Agriculture (CEA), from traditional greenhouses to vertical farming.

CEA methods can produce high-yield, top-quality, nutritious, and delicious food in all seasons – and do it much closer to home. To fight the effects of global warming, the agriculture industry needs to start moving in a direction that reduces its carbon footprint, uses less energy and water, and makes crops less vulnerable to climate change and supply chain interruptions. Controlled growing environments and energy-efficient technologies could be the answer.

Real-world examples
LED grow lights and advances in intelligent lighting control technology enable indoor farmers and greenhouse growers to maximize crop yields, optimize crop quality and standardize production year-round – and do it all sustainably.

In our own webinar with Plenty, the company’s Co-Founder and Chief Science Officer Dr. Nate Storey commented, “At Plenty, the primary tech inputs are LEDs and semiconductor technologies. As the cost of LEDs goes down and the efficiencies go up, we reap the benefits with very little investment on our part.” In fact, the company has “improved yield to the same unit of energy by 12X.”

In Sweden, Ljusgårda AB built a thriving modern farm in what was once a factory. They did this by “replacing the tractor with lights and the shovel with an iPad,” commented Andreas Wihelmsson, Ljusgårda Partner and CEO. The company used intelligent LEDs and light control strategies to reduce their arugula production time by 19%. In our webinar, Wihelmsson noted, “For us, light control is very important to our production. If we look at our collaboration with Heliospectra, we chose to go with ELIXIALEDs because we needed maximum flexibility. The other reason was their positive effect on reducing power consumption.”  

When it comes to greenhouse growing, Bridge Farm Group, the largest commercial producer and supplier of plants in the UK, also achieved significant energy savings with LEDs while lighting twice as much production area as they could with HPS. Using Heliospectra’s high-efficacy, high-intensity MITRA LED lighting solution they saw marked improvements in year-round crop quality. Andrew Fuller, the company’s Technical Director, commented, “Supplemental LED lighting allows us to provide the freshest and most flavorful herbs on the market 365 days a year despite seasonal changes.” He continued, “If you want to put lights on your crop, you want to put it on the most efficient way possible. And today, I think that's LED.”

Using LED lighting technologies in controlled growing environments, these companies were able to accelerate production cycles, put superior products on store shelves, control inventory and time to markets and control costs and increase revenues.
