AI in Agriculture: Hidden Risks to Farmers, Biodiversity, and Food Security
A field can look modern and efficient while becoming more fragile. A drone may scan crops faster than a scout. A sensor may detect stress before the human eye can. A model may predict when to irrigate, spray, plant, or harvest. These tools promise more food with less waste, and in some cases they help farmers make better decisions.
Yet the risks are real. When artificial intelligence enters farming, it does not arrive as a neutral tool. It often comes through expensive machinery, private platforms, data contracts, seed and chemical packages, automated credit systems, and advice apps that few farmers can fully inspect.
That matters because agriculture is not only a business. It is food, work, land, culture, seed heritage, water use, and survival. If AI systems make farming more dependent on a few companies, reduce rural employment, push uniform crops, or encourage chemical-heavy practices, the damage can spread far beyond one farm.
AI in agriculture can help, but without strong safeguards it can also deepen inequality, weaken biodiversity, and make food systems less secure.
Automation can push people out of farm work
Farm labour is often described as inefficient, costly, or hard to manage. AI systems are sold as a way to solve that problem. Autonomous tractors, robotic weeders, automated milking systems, sorting machines, fruit-picking robots, and AI-guided irrigation all reduce the need for human labour in specific tasks.
For large commercial farms, this can look like progress. Machines do not need breaks, housing, wages, or seasonal negotiations. They can work at night. They can repeat tasks with high accuracy. They can be linked to farm management software and run with fewer supervisors.
For workers, the gain is less clear.
Many agricultural jobs are seasonal, informal, and low-paid, but they still support households. Weeding, harvesting, pruning, sorting, packing, spraying, herding, and scouting all create income. In rural areas where formal jobs are limited, even short-term farm work can pay school fees, buy food, or bridge the gap before the next harvest.
When AI systems replace these roles, the loss is not only a line in a farm budget. It can mean fewer earning opportunities for:
Casual labourers hired during planting and harvesting
Young people who learn farming through paid field work
Women who rely on seasonal sorting, weeding, or processing jobs
Skilled tractor operators, sprayer operators, and irrigation workers
Local mechanics if systems are locked to foreign service providers
The risk grows when new machines require specialised training that local workers cannot access. A person who knows how to repair a diesel pump may not be able to service a sensor network, a proprietary robot, or a cloud-controlled irrigation system. The new jobs may exist, but they may go to a smaller group with higher digital skills, often outside the village or even outside the country.
There is also a hidden shift in power. When a farm depends on software, the people who understand the software gain influence. Farm managers may trust dashboards over field workers. A worker who notices a pest outbreak may be ignored if the AI system does not flag it. Local knowledge can become less valued, even when it is based on years of observation.
This does not mean all automation is harmful. Some tasks are dangerous, such as pesticide spraying in poorly protected conditions. Machines can reduce exposure to toxic chemicals. AI can also help older farmers, farmers with disabilities, or farms with genuine labour shortages. The danger comes when labour replacement becomes the main goal and rural livelihoods become an afterthought.
A fair approach would ask hard questions before introducing automation:
Question | Why it matters |
Which jobs will disappear? | Farmers and communities need time to prepare. |
Who will get the new technical jobs? | Benefits should not go only to outside companies. |
Can local workers be trained to repair and manage the systems? | Skills should remain within farming communities. |
Will automation reduce dangerous work or simply cut wages? | Not all labour-saving tools improve welfare. |
If AI makes food cheaper while making rural people poorer, the system has not truly become more efficient. It has shifted the cost onto those with the least bargaining power.
Dependence on technology can make farms more fragile
Traditional farming has always used tools, from hoes to tractors to irrigation pumps. AI is different because it often places decision-making inside complex systems that farmers do not control.
A farmer may use an app to decide when to plant. A soil sensor may guide fertiliser use. A drone may identify pest hotspots. A platform may recommend seed varieties based on weather predictions. A lender may use farm data to approve or deny credit. Each tool may appear useful on its own. Together, they can create a farm that cannot function without constant connectivity, updates, subscriptions, spare parts, and company support.
This creates several risks.
Systems can fail at the worst time. A planting recommendation app may be unavailable during a network outage. A cloud-based irrigation controller may malfunction during a dry spell. A drone may break when a pest outbreak needs urgent scouting. A model may give poor advice because local data is missing, outdated, or drawn from a different region.
For small farms in Kenya and across the region, this matters. Many farming areas still face patchy internet, high data costs, unreliable electricity, and limited access to specialist repair services. A tool that works smoothly in a demonstration plot may not work the same way in a remote village during heavy rains or after a long power cut.
Subscription costs can trap farmers. AI tools are often not one-time purchases. They may come with annual licences, locked software, data charges, upgrade fees, and service contracts. A farmer who builds a production plan around a paid platform may have little choice but to keep paying, even when prices rise.
Repairs may be restricted. Some digital machines are difficult to repair without authorised technicians, special software, or proprietary parts. If a tractor or sprayer cannot be fixed locally, downtime becomes expensive. Farmers may wait days or weeks for support. During planting or harvesting, that delay can mean real losses.
The advice may be too narrow. AI models work from the data they receive and the goals they are designed to meet. If a system is built to maximise yield, it may recommend high fertiliser use, irrigation, and pesticide regimes without weighing long-term soil health, seed diversity, household nutrition, or financial risk.
A farmer may know that a mixed plot of maize, beans, vegetables, and fodder supports the family better than a single cash crop. An algorithm may rate the mixed plot as less efficient because it is harder to measure and predict.
That is one of the deepest risks of AI in farming. It can favour what is easy to count over what is valuable. Yield per hectare matters, but it is not the only measure of a healthy farm. Soil structure, pollinators, water retention, seed saving, fodder supply, household food needs, and resilience during drought also matter.
AI can reduce biodiversity and encourage chemical-heavy farming
Many AI systems are built to make farming more precise. In theory, that should reduce waste. A sprayer can target only weeds. A disease detection model can identify infected plants early. A fertiliser tool can apply nutrients where they are needed.
That promise is real, but it is not guaranteed.
AI can also push agriculture towards uniformity. Algorithms work best when conditions are predictable. A field planted with one crop variety in straight rows is easier for a model to read than a mixed farm with intercropping, trees, cover crops, local seed varieties, and uneven terrain. A monoculture is easier to map, spray, harvest, insure, and finance through a digital platform.
That convenience can come at a high ecological cost.
Monocultures become easier to manage and harder to question
Large farms already have economic reasons to grow uniform crops. AI can strengthen that pattern. Computer vision systems, robotic harvesters, and automated weeders are often trained for specific crop types, plant spacing, and growth stages. If farmers want full use of the technology, they may be encouraged to plant in the pattern the machine can recognise.
Over time, that can reduce crop diversity. Farmers may abandon local varieties because the platform recommends commercial varieties with more data behind them. Seed choices may narrow because the system has been trained on a limited set of crops. Mixed farming systems may be described as messy, even when they protect soil and spread risk.
Reduced biodiversity makes farms more vulnerable. A pest or disease can move quickly through uniform crops. A drought can wipe out a variety that lacks tolerance. Pollinators and beneficial insects struggle when farms lose flowering plants, hedgerows, and varied habitats.
Diversity is not an old-fashioned luxury. It is a form of insurance.
AI can increase pesticide use in some settings
Many companies promote AI-guided spraying as a way to reduce pesticide use. Sometimes it can. Targeted spraying may lower the volume of chemicals applied across a field. Early pest detection may stop an outbreak before it spreads.
Yet AI can also increase pesticide use, depending on how the system is designed and who profits from it.
A disease detection app may flag risk and recommend spraying even when field conditions are uncertain. A slightly over-sensitive model may produce false alarms, especially if it was trained in a different climate or on different crop varieties. A farmer facing possible crop loss may spray “just in case”.
Automated sprayers can also make chemical use easier. If a machine can scan and spray quickly, the practical barrier to repeated spraying falls. A farm that once limited spraying because labour was scarce may spray more often when the process becomes quick and automated.
There is also a conflict of interest when advisory tools are connected to companies that sell pesticides. If the same ecosystem detects pests, recommends products, sells chemicals, and collects farm data, farmers need to ask who benefits from the advice. A recommendation may look scientific, but it may still favour product sales.
The same concern applies to herbicides. AI weed detection can help reduce blanket spraying, but it can also strengthen herbicide-based farming if it makes spraying cheaper and more acceptable. If the deeper system remains dependent on chemicals, precision becomes a cleaner-looking version of the same problem.
The danger is not only the chemical itself. Heavy pesticide use can harm beneficial insects, soil life, aquatic systems, and human health when handled without proper protection. It can also drive pest resistance, which forces farmers into stronger products or more frequent applications.
A narrow AI goal, such as “remove weeds fast”, may ignore wider ecological damage. Good farming needs more than weed-free rows. It needs soil cover, insect balance, natural predators, crop rotation, and healthy water systems.
Small farmers may carry the biggest burden
AI tools often reach agriculture through the language of inclusion. Apps promise to bring expert advice to remote farmers. Digital credit systems promise easier loans. Satellite monitoring promises better insurance. Market platforms promise direct access to buyers.
Some of these tools can help small farmers. The concern is that the risks are rarely shared equally.
A large farm can spread the cost of technology across many hectares. It can hire experts, negotiate contracts, store data, and recover from mistakes. A small farmer has less room for error. One bad season can affect food, school fees, debt, livestock, and seed for the next planting period.
Cost can create a new digital divide
AI-supported farming may require smartphones, data bundles, sensors, drones, subscriptions, compatible machinery, or access to digital payment systems. Even when an app is free, the full package may not be. Farmers may need better devices, paid advisory services, or recommended inputs that cost more than traditional options.
This can split farming communities into those who can afford digital tools and those who cannot. Well-funded farmers may receive better forecasts, credit offers, insurance terms, and market access. Poorer farmers may be labelled as high risk because they lack digital records, not because they are poor farmers.
Once platforms become gatekeepers, exclusion can happen quietly. A farmer without enough data may fail to qualify for credit. A farmer using saved seed may not fit the model. A farmer practising mixed cropping may be harder for satellite tools to assess. The system may treat complexity as risk.
Data may leave the farm but value may not return
Farm data has value. Planting dates, yields, soil conditions, pest outbreaks, input use, livestock movement, and sales patterns can reveal how a region produces food. Companies can use this data to build products, set prices, train models, sell insurance, guide traders, or target farmers with advertising.
Small farmers may provide the data without gaining control over it. Long privacy policies and technical terms can hide the true exchange. A farmer may think they are receiving advice, while the platform is also collecting valuable information about land, production, and purchasing behaviour.
Key questions often go unanswered:
Who owns the data collected from the farm?
Can the farmer delete it or move it to another service?
Will it be sold to input suppliers, lenders, insurers, or commodity buyers?
Can it be used to raise prices or deny services?
Does the farmer understand the agreement in a local language?
Data injustice can become land injustice. In extreme cases, detailed farm data could help powerful actors identify productive land, predict distress sales, or dominate local markets. Even without abuse, unequal data access gives companies and large buyers more knowledge than the farmers who produce the food.
Digital advice can weaken local knowledge
Small farmers often manage risk through local knowledge. They observe winds, soils, seed performance, pests, livestock behaviour, and community seed exchanges. They decide based on household needs as well as market prices.
AI tools may ignore that context. A planting model may suggest a crop that looks profitable but requires inputs the farmer cannot safely afford. A seed recommendation may favour a variety that performs well under ideal conditions but fails when rains are erratic. A fertiliser plan may assume cash is available at the right time.
When advice fails, the farmer carries the loss. The app does not lose the harvest. The platform does not skip meals. The lender may still demand repayment.
This is why accountability matters. If an AI tool influences farm decisions, there should be a clear path for complaint, correction, and compensation when harm results from bad advice or system failure. Without that, the technology shifts risk downward.
Food security can suffer when AI narrows the system
Food security depends on more than producing high yields. A secure food system must be diverse, affordable, locally adaptable, and able to withstand shocks. It should feed households even when fuel prices rise, rains fail, imports slow, currencies weaken, or pests spread.
AI can threaten food security when it encourages farming systems that are efficient in normal times but fragile during stress.
Profit models may favour cash crops over local food
AI platforms often work best where there is clear commercial data. Export crops, high-value horticulture, large grain systems, and contract farming are easier to analyse than informal food exchanges, home gardens, local seed networks, and subsistence plots.
This can steer attention and investment towards crops with strong markets, not crops that local households need most. If digital finance, insurance, and advisory systems favour cash crops, farmers may shift land away from diverse food crops. That can raise household vulnerability, especially where families already buy part of their food.
A farm can earn income and still be food insecure if the crop fails, prices drop, or food prices rise faster than earnings.
Centralised platforms can create new chokepoints
Food systems become risky when too much control sits in too few places. AI can increase this concentration if a small number of companies control farm software, data, seed recommendations, input supply, insurance, credit scoring, and market access.
This creates chokepoints. If a platform changes its terms, raises fees, drops a region, or blocks access, many farmers may be affected at once. If a widely used model makes a wrong prediction, the error can spread across thousands of farms. If a company that manages a key system fails or withdraws support, farmers may be left with tools they cannot maintain.
The same risk applies to cyberattacks and data breaches. As farms become more connected, they also become more exposed. A hacked irrigation system, corrupted advisory platform, or manipulated market app could cause real damage. Food systems should not depend on digital networks that lack strong protection and local backup options.
AI can hide risk behind confident predictions
Weather, pests, disease, soil, markets, and politics are uncertain. AI models can estimate risk, but they cannot remove uncertainty. The problem begins when predictions look more certain than they are.
A colourful dashboard can create false confidence. A farmer, lender, buyer, or government agency may trust a model because it appears precise. Yet the model may be trained on limited data, weak local records, or past conditions that no longer hold under climate change.
In farming, a small error at the wrong time can be serious. Planting too early can waste seed. Spraying too late can lose a crop. Choosing the wrong variety can reduce harvests. Expanding production based on a faulty price forecast can lead to debt.
This is why AI predictions should support human judgement, not replace it. Farmers, extension workers, ecologists, and local communities must remain part of the decision. A model can process data, but it cannot fully understand the social and ecological meaning of a farm.
Safer AI in farming needs rules, rights, and local control
The answer is not to ban all AI from agriculture. Some tools can reduce waste, improve weather warning systems, identify livestock disease, support irrigation planning, or help extension officers reach more farmers. The issue is governance. Who designs the tools? Who owns the data? Who pays when things go wrong? Who gets left behind?
A safer approach would put farmers, ecosystems, and food security at the centre.
Farmers need data rights they can understand
Farmers should know what data is collected, how it is used, and who can access it. Consent should be clear, not buried in long legal documents. Contracts should be available in languages farmers understand. Farmers should be able to move their data, refuse unnecessary collection, and challenge harmful decisions made by automated systems.
Data from small farms should not become a free raw material for companies that return little value to the people who produced it.
Public extension services still matter
AI advice should not replace independent extension officers. Public and community-based advisory systems can provide context that apps often miss. They can compare digital advice with field realities, support farmers without smartphones, and protect farmers from one-sided recommendations tied to product sales.
In Kenya and similar contexts, stronger extension services could help farmers judge when a digital tool is useful and when it is risky. Human support is especially important during drought, pest outbreaks, and market shocks.
Biodiversity should be built into the design
AI tools should not reward monocultures by default. Developers and agricultural institutions can train systems to recognise intercropping, agroforestry, cover crops, local seed varieties, and mixed livestock systems. Tools should measure soil cover, pollinator habitat, water conservation, and input reduction, not only yield.
A model that cannot understand a diverse farm should not be treated as proof that the farm is inefficient.
Farmers should keep non-digital backup options
No farm should become helpless when a server fails. Farmers need ways to operate irrigation, machinery, records, and market access without constant internet. Critical systems should have manual overrides. Local repair skills should be supported. Open standards can reduce lock-in and make it easier to mix tools from different providers.
Resilience means being able to continue when technology fails.
Public policy should protect small farmers
Governments, cooperatives, research institutions, and civil society groups can set standards before harm spreads. Useful safeguards include:
Clear rules on farm data ownership and sharing
Independent testing of AI tools before wide use
Transparency when advice is linked to product sales
Protection against unfair automated credit decisions
Support for local repair and technical training
Public investment in tools that serve small farmers, not only large farms
Environmental checks on systems that may increase pesticide use or reduce crop diversity
These rules should not be treated as barriers to progress. They are the conditions that make progress safer.
AI can make farming more precise, but precision is not the same as wisdom. A system can predict yields and still ignore hunger. It can reduce labour costs and still harm rural livelihoods. It can guide pesticide application and still deepen chemical dependence. It can recommend profitable crops and still weaken local food security.
The hidden risks of AI in agriculture deserve attention now, before farms become locked into systems they cannot question or afford to leave. The safest path is not blind rejection or blind adoption. It is careful use, public oversight, strong farmer rights, and respect for the ecological knowledge already present in farming communities.
Technology should serve the land and the people who work it. When it starts to control them, the cost of efficiency becomes too high.
