The AI tool aims to solve the problem of low dairy production among smallholder farmers by providing tailored (personalized) recommendations that help them enhance their productivity. By leveraging (utilizing) strategies and insights from fellow farmers within the same cluster, the tool facilitates knowledge sharing and best practices, enabling farmers to implement effective techniques that can lead to increased milk yields and improved overall farm performance.

The context of the problem revolves around the challenges faced by smallholder dairy farmers in Tanzania, where dairy farming is a vital cultural practice and a significant economic opportunity. Typically, a dairy household in Tanzania owns 2-5 crossbred or exotic cattle, with only 1-3 cows actively producing milk. As the demand for milk continues to rise in the country, there is an urgent need to enhance milk production to meet this growing market.

Smallholder farmers, who cultivate less than 2 hectares of land, play a crucial role in the agricultural landscape. However, they face several challenges, including the need for competitive and sustainable farming practices that can produce more food, create jobs, and improve the management of natural resources.

The dairy sector's primary goal is to increase production, which necessitates a focus on cultural practices, innovative technologies, and the integration of dairy and cheese production. Achieving high-quality milk production requires specialized skills and knowledge, which many smallholder farmers may lack.

Dairy farming clusters can provide tailored solutions and support, enabling farmers to adopt best practices and transition to higher production levels. By addressing these challenges, the AI tool aims to empower smallholder dairy farmers, ultimately contributing to food security and economic development in Tanzania.

Key complications or risks if the problem of low milk production among smallholder dairy farmers is not addressed:The problem may result in persistently low milk yields, leading to limited income and financial instability. Additionally, inadequate milk supply can contribute to malnutrition due to reduced availability of essential dairy nutrients. This situation would also hinder the farmers' ability to overcome economic challenges, perpetuating poverty and food insecurity.

The specific issue this AI solution addresses is providing tailored recommendations to smallholder dairy farmers on effective methods to increase milk production. Based on the clusters, smallholder dairy farmers can effectively learn and get improvement ideas from their peers. Currently the process of obtaining ideas from fellow farmers has been tested based on farmers’ proximity and self-assessment in which adaptation of best practices from peers to help increase milk yield in Tanzania and Ethiopia took a minimum of 145 days to 290 days for the farmers. This brings in time consumption to reach the optimal solution to the problem.

Symptoms or Indicators of the Issue:

1. Varying Milk Production Levels: High producers average (14.45 ± 5.12 litres), medium producers (11.08 ± 4.29 litres), and low producers (9.15 ± 3.25 litres), indicating a significant disparity in productivity.
2. Transition Needs: There is a clear need for farmers to transition from low to medium and then to high milk production levels.
3. Challenges Faced by Smallholder Farmers: Many smallholder farmers lack the necessary skills and knowledge to improve their production, which is essential for achieving higher yields.
4. Dependence on Sustainable Practices: The need for competitive and sustainable farming practices is critical for increasing food production and managing natural resources effectively.

Without AI intervention, the issue of low dairy production is typically handled through traditional methods such as:

1. Extension Services: Extension officers play a crucial role in providing support to farmers. They offer training, resources, and advice on best practices for dairy farming, including animal husbandry, nutrition, and disease management.
2. Peer Support: Farmers often rely on advice and knowledge sharing from fellow farmers within their communities. This informal network allows them to learn from each other's experiences, successes, and challenges in increasing milk production.

The AI tool aims to provide recommendations to smallholder dairy farmers to transition gradually from low milk production (9.15 ± 3.25 litres) to medium milk production (11.08 ± 4.29 litres) and then to high milk production (14.45 ± 5.12 litres). The solution is based on farm clusters categorized as high, medium, and low milk producers. In this model, low producers learn from medium producers, medium producers learn from each other and from high producers, while high producers collaborate and share knowledge among themselves. This approach fosters knowledge sharing and improvement across all levels, enabling farmers to adopt better practices and enhance their productivity.

Global statistics and trends related to the challenges faced by dairy farmers highlight several significant issues. Despite their expertise in milk production, many farmers encounter challenges such as a lack of education, difficulties in keeping up with current technology, and limited market control.

In recent years, there has been a growing emphasis on peer-to-peer learning initiatives to enhance innovation and sustainability in agriculture. Programs that facilitate demonstration activities among farmers have been employed to improve practices and share knowledge. Farmers are increasingly opening their farms for engagement with peers, allowing for the exchange of ideas and strategies related to food supply chains and agricultural development.

Additionally, various peer learning models, such as Farmer Field Labs and Monitor Farms, have been implemented in different regions to foster collaboration and knowledge sharing. These initiatives aim to address challenges like the high cost of agricultural technology, slow adaptation to new technologies, and the timing of training sessions, which often coincide with busy harvest periods. By focusing on peer-to-peer learning, these projects support farmers in adapting agricultural technologies more effectively and improving their overall productivity.

In Tanzania, the dairy sector is characterized by a reliance on cattle, which account for approximately 90% of the country's milk production. This production primarily occurs within low-input, low-yielding systems, with most of the milk being consumed by the farmers' families rather than sold in the market.

In the Tanga region, the smallholder dairy sector comprises around 6,000 farmers, each typically selling about eight litres of milk daily to Tanga Fresh. Most of these farmers own one to two cows, which limits their production capacity. In contrast, larger operations like the ASAS Group manage a dairy ranch that spans over 4,000 acres and features well-established milking and processing systems. The ASAS Group also plays a significant role in the local dairy economy by purchasing milk from smallholder farmers, ensuring a consistent supply of quality milk for processing.

This context highlights the challenges faced by smallholder dairy farmers in terms of production capacity, market access, and the need for improved practices to enhance their livelihoods and contribute to the overall growth of the dairy sector in Tanzania.

To highlight the need for AI solutions, it is essential to define production systems and identify homogeneous units that represent modern management groupings. By understanding the various attributes of smallholder farmers, strategies can be developed to help them transition from low to high production. This can be achieved through recommendation analysis focused on management strategies related to feeding, health, breeding, extension services, and farmer groups.

In large datasets, association rules serve as "if-then" statements that indicate the likelihood of relationships between data items. Key metrics for evaluating these rules include support, which measures the frequency of the relationship, and confidence, which indicates how often the relationship holds true. These parameters help identify the most significant association rules derived from data analysis, which can then be used to model user recommendations. The goal of this study is to create a recommendation model based on association rules to provide tailored on-farm recommendations to farmers based on their management practices and farm details.

The purpose of the AI tool is to develop a recommendation model using association rules that provides on-farm recommendations to farmers based on their management practices and farm details. This model aims to enhance farmers' learning speed, improve productivity, and facilitate the adoption of new techniques for sustainable dairy production.

The AI tool was developed at the AI4D Lab as part of a Master's research project.

The development of the tool utilized a data mining approach to mine association rules from available secondary datasets. This process involves identifying common patterns, correlations, and links within datasets stored in various types of databases, including relational and transactional databases. The association rules were derived using the Apriori algorithm, and only the relevant rules were employed in training the recommendation model.

The AI tool was trained using three pre-analyzed datasets representing different clusters of milk producers in Tanzania. Cluster one consists of 1,180 high milk producers, cluster two includes 514 medium milk producers, and cluster three contains 294 low milk producers. These clusters are part of six identified clusters from the SOM model. The three clusters were utilized to build the recommendation model for smallholder dairy farmers.

The data validation involved the use of three pre-analyzed datasets, which are categorized into three clusters. Cluster one consists of high milk producers, cluster two includes medium milk producers, and cluster three contains low milk producers in Tanzania. These clusters are part of six identified clusters from the SOM model. Specifically, cluster one contains 1,180 high milk producers, cluster two has 514 medium milk producers, and cluster three includes 294 low milk producers. This structured approach ensured that the data used for training the recommendation model was well-defined and representative of the different production levels among smallholder dairy farmers.

The AI tool functions through the following step-by-step workflow:

1. The farmer enters their farm details, which are sent to the recommender system.
2. The recommendation engine processes the farm details and provides tailored recommendations to the farmer.
3. The farmer rates the recommendations, indicating whether they are helpful or unhelpful, and reports on the status of milk yield improvements.
4. A report is generated for extension officers, detailing the recommendations provided and the farmer's improvements.
5. Extension officers review the report and can offer additional advice to the farmer as needed. (This user is available for advice support)
6. The admin receives a comprehensive report that includes the farmer's ratings, improvements, and the advice given by the extension officers. (This user is available for technical support)
