Revolutionising Farm Management: Revolutionising Farm Management

By Gillian HAMMAH

 Agriculture remains the backbone of Ghana’s economy, employing approximately 30 percent of the workforce and contributing about 18.5 percent to the country’s Gross Domestic Product (GDP) according to the Ghana Statistical Service (2023).

The agricultural sector faces unprecedented challenges as traditional farming methods struggle to meet modern demands. According to the African Journal of Food, Agriculture, Nutrition, and Development, critical constraints to agricultural productivity in Africa include climate change, post-harvest losses, and water scarcity.

The challenge is particularly acute in Africa, where 60 percent to 80 percent of farms still rely on manual operations and hand-held tools. This dependence on manual processes not only impacts efficiency but also leads to significant resource wastage and increased operational costs.

The declining agricultural workforce compounds these challenges, with the farming population in sub-Saharan Africa decreasing from 65 percent to 57 percent despite overall population growth from 700 million to over a billion people.

The AI Solution: Transforming Farm Management Through Technology

The agricultural AI market is projected to reach $4.7 billion by 2028, with field farming comprising 60 percent of this market. This growth reflects the transformative potential of AI-powered farm management systems, which combine drone technology, satellite imagery, and advanced algorithms to revolutionise agricultural operations.

How it works

These systems operate through a comprehensive technological framework:

– Data Collection: Utilising drones and satellites for high-resolution farm imaging

– Advanced Analytics: AI-powered analysis providing tree-level insights

– Real-time Monitoring: Continuous tracking of crop health and growth patterns

– Predictive Modeling: Data-driven forecasting for resource allocation and yield estimation

– System Integration: Seamless incorporation with existing farm management practices

The transformation opportunity

The efficiency gains are substantial and verified. For example, farms implementing these systems have reduced their tree count costs from $3.8 per hectare to US$1.20 per hectare – a 68 percent reduction in labour costs. In other cases, we’ve seen a 1,000-hectare census that traditionally required 50 days with a team of 10 people now be completed in just three days, demonstrating an 80 percent improvement in time efficiency and the ability to reallocate labour to more high-value tasks.

The adoption of AI-powered farm management systems presents a significant opportunity for Ghana’s agricultural sector. According to McKinsey, agricultural productivity in southern and eastern Africa could double or triple with the adoption of modern technologies like crop scouting drones. Research presented at the 3rd International Electronic Conference on Agronomy demonstrates that precision agriculture with AI reduces pesticide and fertiliser use by up to 30 percent and conserves up to 50 percent of water used in irrigation.

Key Benefits for Ghanaian Farms

Improved Efficiency:

A key part of AI-powered precision agriculture solutions is the digitisation of manual processes. Through this, farmers can save time and reduce labor costs, eliminating the need for lengthy and time-consuming paperwork. Tree-level reports on crop health allow farmers to make quick and accurate decisions rather than relying on guesswork.

For example, instead of applying fertiliser at a blanket rate across the farm, farmers will be able to pinpoint the exact trees that need treatment and exclude those that don’t. Precision agriculture solutions also make it possible to examine the exact tree health rather than work with estimates. Additionally, farmers can use AI to visualise plant health through vegetation indexes in order to detect nutrient deficiency before it causes major plant damage.

Reduced Operational Costs:

Drones and satellites are used to handle the bulk of data collection and analysis, reducing fuel, labour, time and maintenance costs associated with traditional methods. For example, manual labour can take months to count the number of trees on a large farm. On top of that, farmers would have to pay them. With AI-powered farm management systems, the time can be reduced to hours, freeing the labour for other manpower-intensive tasks. Furthermore, AI-powered solutions (e.g., tree counting models) typically have a precision rate of over 99 percent, making it just as good if not better than manual counting.

Increase in Data-Driven Decisions:

AI-powered farm management systems are supported by a centralised dashboard to visualise data, which helps farmers to make informed decisions on irrigation, crop rotation, pest control, soil management, and more. For example, the drone and satellite-collected data, such as tree count and blank spots, allows growers to make informed decisions about farming rather than basing their tasks on estimated calculations.

The African Development Bank projects that Africa’s agriculture business will be worth US$1 trillion by 2030. This growth potential can be unlocked through AI-powered precision agriculture, which eliminates guesswork in planting and maintenance processes while providing data-driven insights into soil conditions, tree inventory, and cultivation opportunities.

As Ghana’s agricultural sector modernises, AI-powered farm management systems offer a clear path to improved efficiency and productivity. The documented improvements – from 68 percent cost reductions to 80 percent time savings – demonstrate the tangible benefits of this technology.

For farm managers looking to optimise their operations while ensuring sustainable growth, AI-powered precision agriculture systems represent not just a technological upgrade, but a strategic investment in the future of farming.
