In 2013, an outbreak of (Xf) was identified for the first time in Europe, in the extreme south of Italy (Apulia, Salento territory). The locally identified subspecies turned out to be lethal for olive trees, starting an unprecedented phytosanitary emergency for one of the most iconic cultivations of the Mediterranean area. Xf (Xfp) is responsible for a severe disease, the olive quick decline syndrome (OQDS), spreading epidemically and with dramatic impact on the agriculture, the landscape, the tourism and the cultural heritage of this region.

Pomegranate ( L.) fruits are a historical agricultural product of the Mediterranean basin that became increasingly popular in the latest years for being rich in antioxidants and other micronutrients, and are extensively commercialized as fruits, juice, jams and, in some Eastern countries, as a fermented alcoholic beverage. In this work, four different pomegranate wines specifically designed using combinations of two cultivars (Jolly Red and Smith) and two yeast starters with markedly different characteristics ( Clos and ex- EC1118) were analyzed.

In the last decades, the agroindustry is facing environmental issues due particularly to food loss and waste, requiring a strong orientation towards sustainability and the circular economy (CE) paradigm. This study carries out an investigation of the role of digitalization in serving as a driver to achieve circularity in the agroindustry. A SWOT analysis was performed to assess the strengths and weaknesses (internal factors) and opportunities and threats (external factors) of digitalization in boosting circularity within agroindustry systems and identifying critical factors (CFs).

Purpose: Spent coffee grounds (SCG) are biowastes extensively generated within the coffee supply chain. Nowadays, their disposal represents an increasing environmental concern due to its toxicity and organic nature. With the estimated increase of coffee production and consumption in the upcoming years, there is an imperative need to find a proper reverse option, along with a novel industrial application, which allows for the valorization of this coffee by-product within a circular economy perspective.

Dairy products play a significant role in the human diet, but they are often associated with high freshwater resource depletion. In Italy, the dairy sector represents more than 12% of the total turnover of the agri-food sector. Trentino Alto Adige is the first Italian region in terms of number of dairy farms, but it does not register a quantitatively consistent dairy production.

The spread of COVID-19 has not only led to many deaths but also to social and economic downturn globally. The study represents an exhaustive compilation of relevant macroeconomic data regarding the status of the agri-food sector from a demand side perspective and an overview of the food product producer and consumer prices after the shock. Its main purpose is to assess the resilience level of the agri-food sector to the coronavirus pandemic, analyzing its effect on commodity prices and focusing on the supply and value chain.

Globally, traditional food security fears have been supplemented by concerns about food system sustainability that link current agricultural production practices to damages of environmental ecosystems and the world's climate, thus threatening the natural resource base of future generations. This paper aims at creating a better understanding of the evolution of diet sustainability from 1961 to 2013. Data from the Food and Agriculture Organization of the United Nations were used to investigate the situation for the world as a whole as well as for its macro-regions Africa, Asia, the Americas, Europe and Oceania.

The process of adopting innovation, especially with regard to precision farming (PF), is inherently complex and social, and influenced by producers, change agents, social norms and organizational pressure. An empirical analysis was conducted among Italian farmers to measure the drivers and clarify "bottlenecks" in the adoption of agricultural innovation. The purpose of this study was to analyze the socio-structural and complexity factors that affect the probability to adopt innovations and the determinants that drive an individual's decisions.

Insurance represents one of the main instruments, together with other risk management mechanisms, to face the adverse effects produced by natural calamity that, despite their growing intensity and the enormous costs, are still perceived as "exceptional". Risk management is an important part of farming, and it is a concern for those governments which aim at achieving their agricultural policy targets. In this context, crop insurance can also represent a financial mitigation tool for farmers to face climate change consequences.

In this paper, we present a new approach based on the Grey Water Footprint (GWF) concept for the determination of groundwater nitrate contamination, with a focus on the agricultural impact in the Southern Apulia Region (Italy). The GWF assessment allows us to highlight wells where nitrate contamination is higher and for which a verification of the nature of contamination is necessary, potentially identifying certain contexts associated with risk factors present in the area. Data show higher nitrate GWF values for vineyards than for olive groves, particularly in areas used for the production of table grapes.

In the agribusiness wine is certainly a very interesting sector to analyze. The specific aim of this work is to assess water efficiency and economic water productivity for the Italian wines with Appellation of Origin (AO). This assessment could represent a potential management instrument to improve production performances from a more integrated perspective, pursuing new market trends.

At global scale, the majority of world water withdrawal is for the agricultural sector, with differences among countries depending on the relevance of agri-food sector in the economy. Virtual water and water footprint could be useful to express the impact on the water resources of each production process and good with the objective to lead to a sustainable use of water at a global level. International trade could be connected to the virtual water flows, in fact through commodities importation, water poor countries can save their own water resources.
