In recent years, agricultural robotics has received great attention in research studies, being considered a way to address some important issues of the agricultural sector, such as precision agriculture, resources saving, improvement of safety conditions, and shortage of human labor. These issues are particularly relevant in greenhouse production systems, where many highly repetitive and sometimes dangerous operations are still required to be performed by humans. The purpose of the present review is providing an overview of the research conducted in recent years related to robotic automation for greenhouse applications. The currently available literature about robots and automated solutions for greenhouse applications has been reviewed through the consultation of international databases of journals. A total of 38 publications were included after screening and the information related to each retrieved automated solution was classified. The research highlighted great variability among studies, which often describe automation solutions designed for specific crops and define the specific “supporting tasks” necessary for the completion of a “main task”. Specifically, the technologies used for guidance and navigation systems, crop detection and fruit grasping system, spraying system, and other minor supporting tasks have been described. Furthermore, a critical appraisal of the main challenges of the sector and future research directions are provided.

Vineyards represent complex Mediterranean agrosystems that deliver significant ecosystem services to society. Yet, many vine-growers still need to assimilate the importance of crop and soil management to the conservation of soil and water resources. The main objective of this study was to evaluate water use and the water balance terms in rainfed and irrigated vineyards in Italy and Portugal, respectively, in both cases aiming at the sustainability of natural resources use. The SIMDualKc model is used for both sites after calibration and validation by fitting soil water content measurements. The Italian case study focused on the impacts of inter-row conservation management in hillslope vineyards while the Portuguese case study analyzed irrigation water management under scarcity in flat vineyards. For the Italian vineyards, the model results focused on the evapotranspiration fluxes and their partition, control of surface runoff, and soil water recharge provided by the inter-row soil management using cover crops. Model results of the Portuguese case study showed the need for improving irrigation water use and the terms of water balance, namely referring to percolation and soil water evaporation. Both case studies further demonstrated the advantages of using computational tools to better cope with climate variability in the Mediterranean region and made evident the benefits of improved crop and soil management practices in counteracting land degradation and valuing the use and conservation of natural resources.

Composting represents an alternative for the management of the organic fraction from municipal waste. However, the adoption of compost made from municipal waste is not yet widespread across all European countries, including Italy. Being ‘professional’ (i.e., farmers and gardeners) and ‘hobbyists’ the most representative categories of compost buyers in Italy, this study investigated their attitude toward municipal waste compost adoption and their purchasing pattern, pointing out criticalities and strategies to promote a wider use of this kind of compost. For the two categories of users, frequency of use of different information, buying habits, opinions on marketing issues, and factors which encourage compost utilization were investigated. The ‘professionals’ and ‘hobbyists’ reported different purchasing behaviors in terms of quantity, frequency, and preferred packaging format. The capability of compost from municipal waste to improve soil characteristics and its low environmental impact were identified as the most significant aspects for users, while availability of economic subsidies was not a determining factor for municipal waste compost adoption. With regard to the information sources, the broader use of personal communication channels like peers’ suggestions may have influence on compost adoption pointing out how social influence can promote sustainable behavior and influence users’ purchasing choices.
