description Publicationkeyboard_double_arrow_right Article 2019 FrancePublisher:Elsevier BV Authors: Jehan-Antoine Vayssade; Rémy Arquet; Mathieu Bonneau;Jehan-Antoine Vayssade; Rémy Arquet; Mathieu Bonneau;International audience; Monitoring the position of animals in the outdoors can provide useful information in ecology and in agriculture. A common method is to use active sensors, such as GPS, to record their positions at constant intervals of time. But using active sensors can rapidly become expensive when several animals have to be monitored at the same time. Another method is to use a passive sensor to monitor the entire flock of animals. In this article, we propose a method to process images taken by a commercial drone in order to automate the tracking of animal activities. We developed a method that automatically detects goats from the images and tracks their activity using a combination of thresholding and supervised classification methods. We tested our method on 571 drone images taken over 11 days and found a sensitivity of 74% for animal detection and 78.3% for activity detection.

This paper describes an Expert System that can intelligently diagnose diseases in plants. The system is dialog-based and uses a Multi-Criteria Decision Making technique that is a hybrid of Analytic Hierarchy Process and Sensitive Simple Additive Weighting. The paper describes an approach for disease modeling that uses a set of characteristics which are weighted for each disease using two types of weights: Relative Weights and Scales. The diagnostic process involves calculating the utility value for each disease based on the utility values of its characteristics. Experimental results show an accuracy of over 95%. The system implemented is called AgriDiagnose and it consists of a web-based pathology tool to model the diseases and a mobile app for farmers to interact with the system for disease diagnosis in the field.

This threatens regional food security and can result in environmental degradation if site-specific land management practices are not adopted. AgriMaps is a mobile application developed to support decision making in the agricultural sector of Trinidad and Tobago. This application uses an evidence-based approach to making crop and mitigative land management recommendations. The app is a platform for spatial data visualization and provides a greater range of geo-spatial information than is currently available to stakeholders in the farming community. It is envisioned that this application will improve land use planning decisions and the adoption of sustainable agricultural management techniques. We provide the theoretical and technical frameworks needed to develop similar ICT tools in other territories.
