With population sizes expected to rise quickly in the next decades, will the world have enough to eat? This will very much depend on our ability to keep up with food supply — and do so sustainably.
Smart farming, based on IoT applications, is responding to the challenge by integrating advanced technologies to current farming practices for better results. Perhaps you have come across agbots or agricultural robots?
Equipped with sensors and IoT connectivity, these new automated workhorses can handle different parts of the farming process with remarkable efficiency and precision.
Tractors with computer vision and GPS navigation capabilities are designed to work day and night tirelessly while seeding machines combining geo-mapping and sensor data can plant seeds at optimum depth and spacing.
What’s more, weeding robots with advanced machine learning functions are able to identify and remove weeds, whereas robots with cameras and precise algorithms can delicately harvest fruits without causing damage.
Impressive, don’t you think? It’s a big leap from not too long ago when farmers could only count on themselves to carry labor-intensive tasks while at the mercy of uncoordinated logistics.
Still, one may wonder about the costs of machines taking over the fields and whether we might be looking at these innovations too positively.
New Technologies with a Crop of Challenges
Yes, IoT is sowing the future of food production. But serious challenges are being encountered on the ground.
IoT connectivity poses a huge hurdle in remote locations where communication networks are inadequate or nonexistent. Failing to establish secure and reliable connections can negate the purpose of using IoT devices as these won’t be able to communicate as intended. Without the necessary infrastructure in place, smart farmers won’t know if their crops need tending.
After putting the necessary infrastructure in place, another challenge that needs to be addressed would be network maintenance. The communication network should work seamlessly to ensure the smooth flow of operations. And if you think about it, the devices used in agriculture are exposed to harsh elements, and so may easily get damaged. It is, thus, a must to come up with strategies to ensure sensors and other devices are well- maintained at all times.
Costs and data accuracy
Even where infrastructure is not an issue, IoT systems and the specialists required to maintain them are costly and the data collected is not always accurate — hardly providing farmers with the incentive to invest.
Then, what does mother nature have to say about all that? As smart as farming technologies might be, they have little to no means to influence environmental factors like droughts that render land unusable, storms destroying crops before they can be harvested, or climate change in general.
Last but not least, the IoT industry has to contend with the socio-ethical questions. What happens to laborers whose ability to put food on their families’ tables are under threat from agbots? What should be the role of governments in regulating, supporting, and limiting new farming practices? Can we really trust machines to deal with every aspect of our alimentation?
Smart Farming Applications
Despite its impact on human labor, smart farming is proving its worth in raising productivity through smart applications — notably the following ones:
- IoT sensors on the ground, in the water, or aboard vehicles control crop production and livestock raising.
- Farmers access data collected from the field through low-cost satellite feeds and sensors using tablets and smartphones.
- Agricultural drones keep an eye on the fields and installations and help manage large farms with vast plantations or herds.
- Airborne sensors collect visual and thermal data for surveying, mapping, and monitoring crops and field conditions.
- Sensors identify sick animals enabling farmers to quickly separate them from the herd and prevent the spread of disease.
- Sensors can detect when a pregnant animal’s water has broken and alert ranchers to be on hand for medical support.
- Solar-powered sensors enable farmers to monitor greenhouse conditions including water consumption, light, temperature, and humidity level.
- Farmers can remotely turn on the lights, open a window, activate a fan, lower or increase the heat, or activate misters.
- Sensors installed on water channels activate the flow into furrows or ditches as soil conditions require.
- Sprinkler systems with intruder alert function are automatically activated when sensors detect unauthorized individuals or animals within the irrigated area.
Farm management systems
- Automatic systems collect and process data on the work performed in the fields or at the farm installations.
- Sensors are connected to the Internet, and collected data is stored on cloud servers and becomes accessible from various devices and applications.
The idea behind smart farming is taking root in many parts of the world as the clamor for food security intensifies. It could very well be part of our strategy for survival — or an undertaking that won’t bear much fruit in the foreseeable future.
