2021: the year of AgriTech

In 2021, the potential promised by AgriTech finally arrived. Light Science Technologies looks back at the past 12 months in the sector.

The penny is finally dropping that new technologies such as indoor and vertical farms are critical to solving food insecurity and combating climate change. We're seeing this switch start to gain more momentum post COP26 as we head into 2022, as the urgency of seeking out an alternative food system could not be any clearer.


Agriculture proved to be a hugely disappointing ‘no show' on the conference's agenda - how could it ignore the fact that the sector is directly responsible for up to 8.5 per cent of all greenhouse gas emissions, with a further 14.5 per cent coming from land use change? Where was the mention of indoor farming, which does not pursue the earth's fast depleting energy sources but instead provides a sustainable solution to the world's growing food crisis? However, this glaring omission has only served to fuel AgriTech's ambitions in providing an alternative method to traditional farming.

Investment in AgriTech soars

This year signalled the AgriTech boom, as investors targeted lower-emission food technologies and 2021 saw a record $7.8 billion funding poured into the sector up to the end of the third quarter (and still counting).

Some of the biggest deals included $430 million for California-based company Pivot Bio, which makes alternatives to nitrogen fertiliser, and $321 million for indoor growers Bowery Farming. Meanwhile, in October, ‘home grown' Derby-based Light Science Technologies (LST) raised more than £5 million to float on the stock exchange, strengthening its position in Agritech with its pioneering indoor sensor and lighting technology, with a pipeline of £40.6m of potential business.

AgriTech and the circular economy

Prior to the dire warnings on climate change being laid bare at COP26, the publication of the Circularity Gap Report 2021 underlined the critical need to shift to a circular economy by finding ways to make global resource extraction and processing more sustainable. Stating that the circular economy currently accounts for just 8.6 % of the entire world economy, this made for a grim statistic; it was lower than in 2019 by some 5%.

Sustainable LED grow lighting

Yet this presents a major opportunity for innovative technologies to address the utilisation of agricultural wastes, by-products and co-products, while working towards the goals of improved economic and environmental sustainability. LST's LED grow lights are an example of sustainable product innovation in the AgriTech sector, providing a lighting solution designed to support the circular economy. Typically, LED grow lights are replaced every five years and discarded as landfill waste. In response to this issue, it set about developing its award-winning grow lighting range nurturGROW, which also crucially addressed the key areas of high-performance and cost-effectiveness for indoor growers.

The growing appeal of AgriTech

And it wasn't just the development of product and technologies over the past 12 months that has helped expand AgriTech's appeal, but also the range of crops being grown in a closed environment agriculture (CEA) setting, be it vertical farming, polytunnels or glasshouses. No longer just about leafy greens and a few herbs, indoor farming's crop versatility has extended to tomatoes, peppers, cucumbers, microgreens and soft fruit as well as medicinal cannabis, a global market that reached a value of $7.8 billion in 2020 and is set to accelerate at a CAGR of 15.3% over the next five years.

It is only a matter of time before harvesting strawberries in the dead of winter becomes a reality, with 2021's indoor growing successes including a greenhouse in Lincolnshire where six hectares of strawberries were planted to be among the first to deliver fruit to retailers earlier in the year, and also Waitrose which confirmed its first sale of British ‘Lusa' strawberries in March.

The future of indoor farming

So while 2022 brings further uncertainty as we head into the third year of a global pandemic, this disruptive technology remains on track to shake up the food system and deliver a much-needed step change in how we grow our food. For indoor farming at least, the sky really is the limit.

Innovative SWIR camera for UAV based spectral remote sensing

Allied Vision's compact and light weight Alvium SWIR (short wave infrared) cameras are the ideal choice to build cost-effective OEM systems used in embedded and machine vision applications. The cameras support a spectral range from 400 nm to 1700 nm at high quantum efficiencies. This allows to capture images in both the visible and SWIR spectra with a single camera and enables users to reduce overall system costs! Equipped with Sony's IMX990 and IMX991 SenSWIR InGaAs sensors, Alvium SWIR cameras deliver high image quality and frame rates. This makes them well suited for drones or handheld devices used in various industries such as, agriculture, mining, solar cell inspection or medical.
