Between 10,000 BC and 8,000 BC, the human race witnessed a major step in our evolution – the agricultural revolution. This event paved the way for the transformation of humankind from nomads relying on hunting and foraging, to settlers focusing on agriculture. One of the oldest industries, the agricultural sector has undergone various changes over the ages, adapting to different scenarios and evolutions.

In the 17th century, inventions like the seed drill and the cotton gin caused further changes , reducing workloads while increasing production. During the 19th and the 20th centuries, tractors, chemical fertilizers, and grain elevators became the factors of change. These innovations increased the output quantity and quality to whole new levels while decreasing the workload for humans even further.

The challenges the agricultural sector faces are not the same as a decade ago. IoT, one of the most popular technologies, IoT in agriculture plays a crucial part in helping agriculture rise and meet the ever-evolving demands.


The current landscape

Ever since humans decided on settler agriculture over a nomadic lifestyle, agriculture has been the key to the survival of mankind. Farming is the primary source of livelihood for many people across the globe. Over 19% of our world’s population seeks employment in this sector.

Considering just India alone, 58% of the population depends on farming as their primary source of income. In the USA, agriculture occupies 40% of the land. Even still, 9.2% of the world’s population live in extreme poverty, unable to find the means to satisfy their hunger. Scientists expect the world population to rise from 7.6 billion at the present day to 9.1 billion by 2050. This means that we must adopt newer ways to increase the farming output. The Internet of Things (IoT), along with technologies like Artificial Intelligence (AI) and robotics, display the potential to empower the farming sector and maximize productivity.

The grave challenges of the industry

Though every industry has its own set of challenges, they are a little more extreme in the agricultural sector. With food and clothing being essential commodities, farmers need to get through a plethora of obstacles to meet the rising needs of the rapidly exploding population. According to a special report (2019) by the World Food Programme, 821 million people suffer from starvation, 10 million more than in the previous year. These stats mean that 1 in 9 people suffer from hunger worldwide.

The agricultural land around the globe suffers from various factors. Climate change, natural disasters, and land degradation are key factors that damage farmlands. Let’s have a deeper look at these factors.

Climate change

Climate change is real and affects every single one of us badly in some way or the other. The agricultural sector is both a victim and an offender when it comes to climate change. Natural disasters like floods, droughts, and heavy storms harshly affect crops and farming lands. On the other hand, agriculture is also one of the major producers of greenhouse gasses, which are the primary cause of climate change.

Agricultural waste

The high amount of food and agricultural waste produced is alarming. According to the United Nations’ Food and Agricultural Organization, over 1.3 billion tonnes of food gets lost or goes to waste. These statistics concern the food that humans alone consume,never mind the wastage of cattle feed, manure, and so on.

The more the waste, the more greenhouse gas emissions. Agricultural waste also affects the margin of profit for the farmer.

Impact on the soil

The usage of fertilizers and chemicals on crops needs proper planning. The improper use of these fertilizers, pesticides and other chemicals can result in them breaking down the soil chemistry and composition, depriving the soil of the nutrients that crops require. Apart from fertilizers, improper use of crops results in the soil losing its nutrients.

Farm lands are prone to soil erosion due to various factors. This also takes a heavy toll on the productivity of farming.

Enter IoT

The Internet of Things (IoT) has disrupted all industries, and agriculture is not an exception. IoT, along with artificial intelligence (AI) and other technologies, is the driving force behind concepts and products like wearables, smart cities, driverless cars, etc. However, the biggest impact of IoT is evident in the agricultural sector.

Throughout history, the agricultural sector has undergone massive innovations. This industry relies heavily on new ideas and technology to meet the ever-rising demand for food supply. With the advent of IoT, farmers have realized their ability to produce crops at a lesser cost. IoT is gaining vast popularity among farmers. Recent reports suggest that the amount of connected IoT devices in the agricultural industry will rise to 225 million in 2024 compared to just 13 million in 2014.

The lack of a stable internet connection was what hindered IoT adoption in its early days. However, with more internet service providers coming up and the availability of faster connectivity, IoT adoption is on the rise.

At first, using the sensors in devices, farmers monitor the water level of their tanks in real-time, helping them set up an efficient irrigation process. Now, with ultra-modern and powerful sensors, the power of IoT in the agricultural sector is vast, enabling farmers to track each step, right from planting the seeds to marketing their produce.


The adoption of IoT helps farmers in multiple ways. Primarily, it helps them reduce their costs while increasing their yields. IoT also helps farmers make informed decisions. Let’s look at the various benefits of IoT in the agricultural sector.

Tracking climatic conditions

The success of agriculture is highly contingent on climatic conditions. Farming with vague knowledge about the climatic conditions results in the deterioration of the quantity and quality of crops. IoT technologies help farmers understand climatic conditions in real-time. Sensors outside agricultural fields collect environmental information, which helps farmers choose crops that suit the climatic conditions. The IoT ecosystem detects metrics like humidity, rainfall, temperature, and other climatic conditions accurately. Various sensors record the data and configure it to suit the situation. The system sends alerts whenever weather changes occur. The system also eliminates the physical presence of farmers in some situations. Overall, these IoT devices help farmers increase their productivity and the quality of crops.

Precision farming

Precision farming, or precision agriculture, is one of the major applications of IoT in this sector. The practice makes farming more precise, giving farmers absolute control over many aspects. Precision farming leverages the power of smart applications like livestock tracking, inventory management, vehicle monitoring, and field observation. The technique analyzes the data captured by various sensors and acts accordingly. Farmers get accurate information about their stock or crops, prompting them to make quick and efficient decisions. There are a plethora of precision farming techniques like irrigation management, livestock control, warehouse management, and more. These techniques are vital to increasing the productivity and quality of the crops. You can even analyze the soil conditions and other parameters like the water and nutrient levels to up the operational efficiency and detect real-time working conditions of the devices.

Smart greenhouses

Greenhouse farming is another popular agricultural technique that farmers widely use globally. With the advent of IoT, greenhouse farming has gotten smarter. The IoT-based system powers the greenhouse stations to adjust climatic conditions to specific needs. For example, the sensors in a greenhouse station send data like water consumption rates, humidity, and temperature to a central controller via email or SMS. As per the data, the system carries out automated and accurate smart irrigation procedures.

As the process is automated and requires no human intervention, the technique is cost-effective and accurate.
