“…This high yield, with respect to other countries in which production ranges from 12.9 to 15.2 kg/m 2 [55,56], has been reached thanks to the positive effects of drip irrigation, plastic mulch, sandy soils and Sicilian climatic conditions that grant a rapid tomato growth [57][58][59][60][61][62][63].…”

Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, both from the perspective of the farm, as well as from that of the entrepreneur, the aim of this paper was to analyze the economic sustainability of Sicilian greenhouse cherry tomato cultivated in the Ragusa Province. In particular, an economic analysis on 30 representative farms was conducted in order to estimate production costs and profits of greenhouse cherry tomato. According to our results, the lack of commercial organization, which characterizes the small farms we surveyed, determines low contractual power for farmers and, consequently, low profitability.

Several environmental parameters, including solar radiation, temperature, and runoff coefficient (D'Asaro and Grillone 2012; Grillone et al 2012Grillone et al , 2014, showed significant variation among Mediterranean areas and might drastically effects pathology epidemiological dynamics. Usually, primary infections occur at the beginning of the growing season, while secondary infections, spread by vectors, lead to an irreversible, symptomatic disease stage with consequent production loss.…”

International audiencePlant diseases are responsible for major economic losses in the agricultural industry worldwide. Monitoring plant health and detecting pathogen early are essential to reduce disease spread and facilitate effective management practices. DNA-based and serological methods now provide essential tools for accurate plant disease diagnosis, in addition to the traditional visual scouting for symptoms. Although DNA-based and serological methods have revolutionized plant disease detection, they are not very reliable at asymptomatic stage, especially in case of pathogen with systemic diffusion. They need at least 1–2 days for sample harvest, processing, and analysis. Here, we describe modern methods based on nucleic acid and protein analysis. Then, we review innovative approaches currently under development. Our main findings are the following: (1) novel sensors based on the analysis of host responses, e.g., differential mobility spectrometer and lateral flow devices, deliver instantaneous results and can effectively detect early infections directly in the field; (2) biosensors based on phage display and biophotonics can also detect instantaneously infections although they can be integrated with other systems; and (3) remote sensing techniques coupled with spectroscopy-based methods allow high spatialization of results, these techniques may be very useful as a rapid preliminary identification of primary infections. We explain how these tools will help plant disease management and complement serological and DNA-based methods. While serological and PCR-based methods are the most available and effective to confirm disease diagnosis, volatile and biophotonic sensors provide instantaneous results and may be used to identify infections at asymptomatic stages. Remote sensing technologies will be extremely helpful to greatly spatialize diagnostic results. These innovative techniques represent unprecedented tools to render agriculture more sustainable and safe, avoiding expensive use of pesticides in crop protection

Nowadays, food waste is one of the main global paradoxes and raises profound questions from the social point of view. The causes of food losses and food waste are varied and differ according to the various stages of the food chain. The problem of food waste prompted the European Parliament to proclaim 2014 the "European year against food waste" and to adopt a resolution which should lead to a reduction of 50% of waste by the year 2025. This study proposes the possible corrective actions, to be taken at the level of retail distribution and facing the end customer, to achieve the goal reducing of food waste (Fiore et al., 2008). The research was conducted by a group of scholars of the Department of Economics, Business, Environmental and Quantitative Methods, at the University of Messina, on a sample area of eastern Sicily. In particular thirteen retail outlets were analyzed by collecting and processing data on sales, broken down by sector, for the period 2009 to 2013. The research conducted has shown that the food sector that contributes most to food waste, in the area investigated, is that of fruit and vegetables, the study has provided a detailed analysis of the ten most wasted foods. The work finally comes to processes that involve many different scenarios for reducing waste, encouraging a comparison, of the products most wasted, by providing potential solutions or corrective actions aimed at reducing the phenomenon analyzed.
