Global food insecurity is on the rise, driven by an increasing population, climate change, and economic uncertainty. According to the World Food Program (WFP), the number of people facing acute food insecurity increased from 135 million in 2019 to 343 million in 74 countries by 2024. Not surprisingly, 80% of the global population most at risk from crop failures and hunger are located in Sub-Saharan Africa, South Asia, and Southeast Asia, where farming families are disproportionately poor and vulnerable.
To address the pressures of growing food demand and climate change, policymakers and industry leaders in these regions are seeking assistance from technological advancements like Big Data, the Internet of Things (IoT), and cloud computing. The applications of Big Data in agriculture are vast. The ability to track physical items, collect real-time data, and forecast scenarios can significantly transform farming practices, improve productivity and tackle the issue of food insecurity especially in Africa.
Let’s take a closer look at what Big Data entails, as well as the challenges and benefits it presents for farmers in Africa.
What is Big Data
Big Data was introduced in 2005 to describe large and diverse data sets that cannot be processed using traditional data management techniques. The term encompasses three key aspects: the volume of information, the velocity or speed at which it is generated and collected, and the variety or range of data points included. These are commonly referred to as the “Three V’s” of Big Data.
Data analysts use Big Data to examine the relationships between different types of information, such as demographic data and food purchase history, to determine if any correlations exist. The goals of utilising Big Data include increasing efficiency by reducing the time and resources required for production, supply chain management, and improving product quality.
What is Big Data in Agriculture
In agriculture, the term “Big Data” refers to the vast amounts of information collected from various sources on the farm and analysed to extract relevant information to improve production.

The first phase of this process involves data collection, facilitated by IoT devices. Sensors installed in tractors, trucks, fields, soil, and plants gather real-time data directly from the ground.
Next, analysts integrate this large volume of collected data with other available information in the cloud, such as weather data and pricing models, to identify patterns.
Finally, these patterns and insights help address existing problems. They assist in identifying operational inefficiencies and issues with soil quality and help develop predictive algorithms that can alert farmers to potential problems before they occur.
Key Applications of Big Data in Agriculture
Big Data in agriculture has several applications including:
1. Precision Farming
Big Data is important for precision agriculture. By gathering detailed information from the fields like soil moisture and nutrient levels farmers can adjust their use of water, fertilisers, and pesticides based on actual needs. Instead of relying on instincts or experience, farmers can now refer to real data, such as soil moisture, weather conditions, and crop health. This helps them use resources only when necessary, which reduces waste and increases yields.
2. Yield Prediction and Forecasting
Farmers always want to know how much they will harvest, and Big Data provides precise estimations. Predictive models can estimate crop yield before planting by analysing past weather, soil conditions, and crop performance. For example, a farmer can use data to decide if planting a specific crop is worth it this season or how much fertiliser to apply.
3. Transportation and Storage
Transporting crops from the field to the market requires many steps, and Big Data helps make this easier. By examining data from the supply chain, including the best route for transportation, weather conditions and best storage practices for longer shelf life, farmers can ensure their produce arrives at the market quickly and in good shape.
4. Predictive Equipment Maintenance
When farm equipment break down, it can cost farmers a lot of money. Predictive maintenance uses sensors and cameras to detect potential problems in real time, helping to prevent breakdowns. For example, a change in vibration or temperature can be an indicator of a future failure.
5. Sustainable Agriculture
Big Data helps farmers use resources more efficiently and minimise waste, which protects the environment. This could mean using less water, applying fewer chemicals, or choosing crops better suited for the local climate. The aim is to farm in ways that benefit both the environment and profitability.
6. Livestock Health Monitoring: Monitoring livestock health is vital, and Big Data makes this task easier. If a cow is eating less than usual, the system alerts the farmer to investigate before it becomes a serious issue. Using Big Data, farmers can detect sickness easily, treat injuries, and prevent disease from spreading.
Challenges and Risks Associated with Big Data in Agriculture
While Big Data has the potential to revolutionise the agricultural sector, there are still several challenges facing the adoption of technology in the sector. They include:
1. Data Quality and Integrity
A major challenge in using Big Data in agriculture is maintaining data quality and standardisation. Different data sources can have various formats, accuracy levels, and reliability. This inconsistency can make it hard to combine and analyse data effectively.
2. Data Security and Privacy
Analysing data in agriculture involves sensitive information about land, crops, and farming methods. Sharing this farm data can feel risky. Smallholder farmers might worry about larger companies taking advantage of them, while bigger farms may fear having their competitive strategies exposed.
3. Data Storage and Management
Agriculture produces a lot of data from different sources, like sensors, satellite images, and historical records. Managing and storing this data can be tough. Traditional systems may struggle to handle large volumes, causing slow performance and delays in analysis.
4. Lack of Technical Expertise
To achieve accurate results in Big Data projects, it is essential to properly collect, structure, and clean the data. This need creates a high demand for skilled Big Data analysts. However, finding top talent can be challenging due to this high demand. Many farmers and stakeholders in the agriculture industry unfortunately lack the skills necessary to effectively collect and analyse data. Specialised skills such as data science, machine learning, and artificial intelligence are crucial for analysing and interpreting Big Data.
5. High Cost
Big Data sources like IoT sensors, drones, and satellite imagery enable farmers to gather large amounts of information about their crops and operations. However, this data is often spread across different platforms and may not work well with other systems. Farmers need to invest in data integration tools to combine all their data in one place, and these tools can be expensive. Especially for small-scale farmers.
Overcoming Challenges and Mitigating Risks of Big Data
To effectively tackle the challenges of integrating Big Data in agriculture for African farmers, all relevant stakeholders in the sector need to collaborate and foster a supportive environment for Big Data adoption. Some potential solutions to achieve this include:
1. Investing in Data Infrastructure
The government, farmers, investors, and other stakeholders in the agritech sector should prioritise the development of efficient data infrastructures. For example, investing in a consolidated data platform is essential for effectively managing and analysing various agricultural data. These platforms facilitate data visualisation, analysis, and reporting, enabling farmers to identify trends, patterns, and areas for improvement. More investments in agritech companies creating such data platforms can simplify decision-making and enhance overall farm productivity.
2. Implementing Strong Data Governance Policies
More focus should be placed on establishing robust data security measures. All data platforms should be mandated to provide end-to-end encryption and clear data usage policies. It is also vital to guarantee that data ownership stays with the farmer, which allows them control over how and with whom their information is shared.
3. Collaborating with Experts
Teaming up with technology companies can give farmers access to sophisticated Big Data solutions and insights. These partnerships can vary from joint research initiatives to the use of commercial data analytics platforms. Through the capabilities of technology partners, farmers can take advantage of advanced data analysis methods, customised software solutions, and continuous support.
