Special Issue Information

Dear Colleagues,

In "The 2030 Agenda for Sustainable Development", the United Nations (UN) and the international community set the target of eliminating global hunger by 2030. However, the world’s population is anticipated to reach to 10 billion by 2050, as per a 2018 report by the World Resources Institutes (WRI). Hence, to fulfill this anticipated increase in food demand, the use of artificial intelligence (AI)-, IoT- and smart sensor-based precision agriculture and precision livestock is inevitable. The aims of precision agriculture and livestock are to improve productivity, increase yields and profitability and reduce environmental footprints through techniques such as efficient irrigation, the targeted and precise use of pesticides and fertilizers for crops, and the vaccination scheduling and tracking of livestock. The implementation of AI, IoT and smart sensors can bring promising developments and innovations to agricultural sectors through data science, computer vision and deep learning-based algorithms.

The main purpose of this Special Issue is to identify and report innovative and novel research outcomes on the application of AI, IoT, smart sensors, machine learning, deep learning, remote sensing and autonomous systems in smart farming and precision livestock. At the same time, we welcome contributions on the use of advanced sensors, sensing systems and field instrumentation in smart agriculture.

Contributions may include, but are not limited to, the use of autonomous tractors, sprinklers and other instruments; infestation detection and removal using UAV images; crop health monitoring and yield prediction; smart and autonomous irrigation; soil mapping and fertilizer advisories; vegetation stress identification; livestock monitoring; tracking and controlling; vaccination scheduling of livestock; and the use of big data and high-performance computing for agriculture and livestock.

Animal welfare in barns is strongly influenced by air quality, with gaseous emissions like ammonia posing significant respiratory health risks. However, current state-of-the-art ammonia monitoring systems are labor-intensive and expensive. Metal Oxide Semiconductor (MOS) sensors offer a promising alternative due to their compatibility with sensor networks, enabling high-resolution ammonia monitoring across spatial and temporal scales. While MOS sensors exhibit high sensitivity to various volatile compounds, temperature-cycled operation is commonly employed to enhance selectivity, effectively creating virtual sensor arrays. This study aims to improve ammonia detection by designing a virtual sensor array through a cyclic data-driven approach, integrating machine learning with solid-state sensor modeling. The results of a two-week dataset with measurements of four different pig barns demonstrate ammonia sensing with a sampling rate of about 2/min and a range of 1–30 ppm. The method is robust and exhibits a 10% increase in normalized RMSE when comparing testing results of an unseen sensor module with results of the training dataset. A filter membrane boosts accuracy and prevents data loss due to contamination, such as flyspecks. Overall, the used MOS sensor BME688 is effective and economical for widespread continuous ammonia monitoring and localization of ammonia sources in pig barns. Full article
