Rapid spread of Varroa destructor mite has resulted in high honeybee colony losses. Common monitoring practices are time consuming, manual and operator dependent. This work proposes a camera-based system, integrated inside the beehive, by means of an instrumented honeycomb. The goal is to design a monitoring system for detecting youngest infected bees during the warm seasons and foretic mite throughout the winter, providing the level of infestation inside the hive. Constraints and limits of the designed experimental setup are discussed.

The development of methods and techniques for reconstructing olive tree canopies by point clouds is a long-established topic challenging many researchers. Using Mobile Laser Scanner, we measured single tree parameters in an olive grove in Cartoceto, Italy. The area is a well-known geographical indication agreed by Italian law by Protected Designation of Origin (PDO). According to the agronomic practice, we first estimated the canopy volume using geometrical primitives (paraboloid and toroidal) as ground truth. We have finally compared the canopy values with the volumes obtained by mesh algorithms: Convex hull and Alpha shape, to statistically compare pairwise correlation (Paraboloid - Convex hull $boldsymbol{mathrm{R}^2=0,92}$ and Toroid - Alpha shape $boldsymbol{mathrm{R}^2=0,91)}$. This preliminary analysis provides a theoretical benchmark for future implementations, such as the possibility of including LiDAR (Light Detection and Ranging) in the mechanized pruning process.

The recent deployment of GNSS-RTK positioning on remotely piloted vehicles has increased real-time positioning accuracy by almost three orders of magnitude. This not only provides a significant geometric improvement but, in practice, makes possible some applications that were simply not possible before. For example, positioning crops with centimetre accuracy makes it possible to distinguish a single plant and to detect or treat that very plant without any possibility of misunderstanding. This is obviously not possible with ‘traditional’ drones that work in ‘point positioning’ with indeterminacies of even tens of metres. In this paper we will illustrate how the possibilities of RTK can be applied to a specific vinepathology. The symptoms of the flavescence dorée and bois noir are grouped into the so-called Grapevine Yellows (GY). These diseases are affecting the viticultural regions worldwide and all varieties and rootstocks seem susceptible but with varying degrees of severity. Typical symptoms include discolouration and necrosis of leaf veins and leaf blades, downward curling of leaves, lack or incomplete lignification of shoots, stunting and necrosis of shoots, abortion of inflorescences and shrivelling of berries. The compulsory control plan for the fight of these diseases includes both the use of insecticides and the eradication of the vines. This latter is part of a monitoring plan of the grapevine yellows that aims to identify outbreaks of the disease and its progression and limit the compulsory phytosanitary control only in the truly affected areas. The identification of the GY is a very time-consuming technical work because each vineyard must be visually inspected plant by plant. This type of monitoring is made even more difficult in the case of steeply sloping vineyards and where the vineyard landscape is fragmented. So, we raised the following question: is it possible to use Unmanned Aerial Vehicles (UAVs or drones) to remotely monitor the vines that are difficult to reach and identify the grapevine yellows? We present here the results of our field tests made in Trentino (IT) with different drone models (prosumer and professional) and with different types of image acquisition sensors (RGB and multi-spectral).

Soil erosion induced by rainfall is mainly due to the rainfall impact besides the consequent surface runoff. Rainfall kinetic energy is the most used variable to represent its erosivity. The latter represents the weathering attitude to erode soil and is a fundamental variable of the erosion process. Consequently, precise measurements of rainfall erosivity have to perform to develop a reliable prediction model of the erosive phenomenon. Currently, impact energy can be reliably measured only by disdrometers. These instruments measure the Drop Size Distribution (DSD) which, joined with the raindrop falling velocity, allow to calculate, by integration, the impact kinetic energy. However, disdrometers are expensive tools that imply to collect and process a remarkable amount of data, and for these reasons, they are not suitable for land large scale use. Without direct measurements, the rainfall impact energy is currently estimated using only the rainfall intensity, widely detected by the recording rain-gauge network operating all over the country. Recently, an innovative method to measure the rainfall energy, subject of a patent, has been proposed. This method is based on the simultaneous detection, in a given time interval, of the rainfall intensity and the number of raindrops that hit a specific surface. In this paper a theoretical analysis aimed at improving the reliability of this rainfall energy measurement is firstly presented. The developed analysis accounts for the detection of a further variable deriving from the momentum distribution. Then, the reliability of the proposed approach was tested using 44,695 DSDs recorded in Palermo in the period 2006–2014. Using the proposed approach, the reliability of the rainfall energy measurement can significantly improve.

Black Soldier flies (BSFs) are very effective for the treatment of organic waste and their transformation into insect proteins and oils that can be used to produce feed and biofuels. An increasing number of startups and companies are breeding BSFs to take advantage of the numerous potential applications due to the larval diets. Although the breeding of BSF larvae requires artificially controlled conditions, methods for the characterization of the life cycle in production plan are lacking. Most of the analyses and procedures available in the literature cannot be used within the production lines of breeders. In the present study, an exploration of non-contact measurements (RGB video, thermal, Hyperspectral imaging) and of the analysis methodologies was carried out in order to identify the ones which are most significant for the different phases of the BSF life cycle, and which can be automated within the production lines. The result of the study was the definition of the criteria for the characterization, through non-contact measurements of the life cycle of the BSFs: computer vision algorithms based on image and data acquisitions were developed using 1) RGB camera for size / weight estimation and movement / vitality for the phases where the nutritional substrate is not present (pupae); 2) IR camera for the evaluation of movement / vitality for the phases where the nutrient substrate (larvae) is present and for the identification of temperature anomalies (metabolism too slow or too fast); 3) hyperspectral chamber to evaluate the growth of the larvae in relation to the chosen diet.

In recent years, emerging technologies have allowed the measurement, analysis, and control of many processes. Many researchers have taken particular attention to developing smart sensing solutions for different fields, such as Smart Industries, Smart Metering, Smart Building, and so on. However, this new enabling and emerging technologies can also be used to analyze and improve craft operation processes in agriculture. An example is the natural fig drying process, usually made adopting only natural sources. In this case, the process is regulated by the availability of unpredictable climate conditions, so the correct detection of the drying process ending point represents an essential aspect of improving the drying process throughput. The paper aims to describe the design of a smart sensing system made for monitoring the fig drying process, measuring different parameters such as the drying temperature and relative humidity and correlating them with the weight loss and water activity of figs. The analysis of data collected during the drying process has been reported and discussed to demonstrate its effectiveness in speeding up the drying process.

Digital field recordings are central to most precision agriculture systems since they can replicate the physical environment and thus monitor the state of an entire field or individual plants. Using different sensors, such as cameras and radar, data can be collected from various domains. Through the combination of radio wave propagation and visible light phenomena, it is possible to enhance, e.g., the optical condition of a fruit with internal parameters such as the water content. This paper proposes a method to correct sensor errors to perform data fusion. As an example, we observe a watermelon with camera and radar sensors and present a system architecture for the visualization of both sensors. For this purpose, we constructed a handheld platform on which both sensors are mounted. In our report, the radar is analyzed in terms of systematic and stochastic errors to formulate an angle-dependent mapping function for error correction. It is successfully shown that camera and radar data are correctly assigned with a watermelon used as a target object, demonstrated by a 3D reconstruction. The proposed system shows promising results for sensor overlay, but radar data remain challenging to interpret.

The NASA Global Precipitation Measurement (GPM) Integrated Multi-satellitE Retrievals for GPM (IMERG) product is one of the few gridded precipitation products available at a sub-hourly temporal scale. This high temporal resolution is required in many hydrological applications, including the estimation of the rainfall-runoff erosivity factor R, used in the USLE and RUSLE soil erosion prediction models. In this study, through a comparison with data measured at two rain gauges in central Italy, the limits and potential of the GPM-IMERG product on O.t-degree resolution in providing estimates of the R-factor are highlighted. Results indicate that the product can provide accurate estimates in areas relatively homogeneous from an orographic and climatic point of view. On the other hand, it fails to identify the gradients of both precipitation and erosivity that characterize more complex areas, such as those close to the mountain ranges.

A fast and reliable estimation of building energy need is essential in agricultural building design, nonetheless, a large number of simulations is required to obtain better energy saving solutions. The aim of this work is to understand if machine learning can substitute numerical simulations and speed up the building design process and assess the incidence of specific architectural elements. Supervised regression models has been trained and tested in a data-set of thousands simulations performed on a case-study agricultural building. Among the algorithms, the tree-based Extreme Gradient Boosting showed the best performance. A study on model explainability has been carried out using SHAP and features importance, which is fundamental to help academics and professionals devise better design strategies for both new constructions and retrofitting interventions.

The aim of this work is to understand if machine learning can substitute numerical simulations and speed up the building design process and assess the incidence of specific architectural elements. Supervised regression models has been trained and tested in a data-set of thousands simulations performed on a case-study agricultural building. Among the algorithms, the tree-based Extreme Gradient Boosting showed the best performance.
