Genetically modified (GM) crops are unpopular. Despite their vast potential to help improve global food security while reducing pesticide use, many countries are extremely resistant to planting GM crops, with 85% of global GM agricultural land coming from just four countries: the US, Brazil, Argentina and Canada. Where they have been grown, GM crops have been very successful, to the point where more than 90% of the soybean, corn and cotton crops grown in the US are GM. A 2014 meta-analysis found that an average farm can increase yields by 22%, reduce chemical pesticide use by 37% and increase farmer profits by 68%. Despite this, difficult regulations and consumer hostility have meant that growth in GM crops has been stagnant for much of the last decade, with companies instead turning their attention to gene editing in crops.

GM crops remain hugely controversial, to the point where (former) GM giant Monsanto is a synonym for corporate evil to many consumers. Gene editing could be set to become the next revolution in agriculture, allowing the precise editing of specific genes without introducing foreign DNA into the final crop. However, for it to truly become a game-changing technology, developers will need to avoid making the same mistakes that were made with GM crops in the 1990s.

A consistent mistake that the industry made was relying on the science to try and persuade the public while neglecting the emotional aspects of the debate. When Monsanto attempted to introduce its glyphosate-resistant soybeans in Europe in the 1990s, it attempted to brush off criticism, leading to a war of words with environmental groups. Here, the environmental groups had the upper hand, capitalising on the public’s fear of the unknown, especially in relation to emotional triggers of personal health and safety, something that continues today. Additionally, its approach to protecting its IP – suing farmers for violating terms of service – drew intense criticism from consumers who viewed seeds as being part of the natural world that belongs to everybody.

Successfully commercialising gene-edited seeds will require a careful approach. This will require a meaningful dialogue with consumers, addressing the wider emotional concerns around GMOs whilst also engaging in efforts to educate the public around the technology and improve wider scientific literacy. However, navigating this space in an open and inclusive manner while also protecting IP and investments could be a serious challenge.

“Crop Biotechnology 2020-2030”, the new report by IDTechEx, explores and contrasts gene editing and GM technologies, analysing the scientific, market and consumer factors needed to make gene editing a success.

Agricultural Robots and AI: A Question of When rather than If

Agricultural Robots and AI: A Question of When rather than If


Robotics and artificial intelligence (AI) will drive a deep and transformative change in the agricultural world during the coming decades. Seeing, localising, and taking plant-specific intelligent action are no longer the exclusive realm of humans. Machines have demonstrated the technical viability and the emphasis has long shifted to the finer details of ROI, reliability, business model, etc. As such, a new class of activities in agriculture are prone to automation, just as advances in power and motion technologies mechanized many agricultural tasks, or just as advances in seed and agrochemical technology removed the human from many activities. 

In an article published by market research firm IDTechEx, which has studied the technologies, applications, products, and players in agricultural robotics and AI for the past five years, the firm argues that the upcoming changes are already a question of when and not if. The article is based on the IDTechEx report “Agricultural Robots, Drones, and AI: 2020-2040: Technologies, Markets, and Players”, which covers the latest developments and reflects our latest insights, analysis, and market projections.  

The transformation will not be overnight, but nonetheless, robotics and AI are an inevitability in the evolution of agricultural tools and practises. The scale of the potential is demonstrated in the chart below, which shows the forecasted long-term growth in annual unit sales (vs accumulated fleet size) of various autonomous and/or robotic solutions.

Agricultural Robots: A Cost-Effective Precision Revolution?

Machine vision technology is often a core competency of these robots, enabling the robots to see, identify, localise, and to take some intelligent site-specific action on individual plants. The machine vision increasingly uses deep learning algorithms often trained on expert-annotated image datasets, allowing the technology to far exceed the performance of conventional algorithms and to match or even exceed even that of expert agronomists. Crucially, this approach enables a long-term technology roadmap, which can be extended to recognise all types of crops and to analyse their associated conditions, e.g., water-stress, disease, etc.

Many versions of this emerging robotic class are autonomous.  The autonomy challenge is much simpler than a car. The environment is well controlled and predictable, and the speed of travel is low. The legislation is today a hindrance, including in places such as California, but will become more accommodative relatively soon.

The rise of autonomous robots, provided they require little remote supervision, can alter the economics of machine design, enabling the rise of smaller and slower machines. Indeed, this elimination of the driver overhead per vehicle is the basis of the swarm concept. There is clearly a large productivity gap today between current large and high-power vehicles and those composed of fleets of slow small robots. This productivity gap however can narrow as the latter has substantial room for improvement.

The first major target market is in weeding. The ROI benefits here are driven by labour savings, chemical savings, boosted yields, and less land compaction. Precision action (spraying, mechanical, or electrical) reduces consumption of agrochemicals by 90% compared to untargeted application.  It also improves yield (e.g., by 5-10%) because collateral damage of the crops by untargeted chemical application can be minimized. This technology can further enable farmers to tackle herbicide-resistant weeds, which are a growing problem, especially in some hotspots. Finally, the robots leave behind no unusable compacted soil.

These robots are evolving. Many robots have already grown in size and capability, offering faster speeds, higher frame-per-seconds, more ruggedised designs, higher on-board energy for longer operation time and a heavier load, and so on. This evolution will inevitably continue, just as it did with all other agricultural tools and vehicles. We are still at the beginning. The deployed fleet sizes worldwide are small, but this is about to change (see the chart above).
