Harvesting system sustainability in Mediterranean olive cultivation: Other principal cultivar.

In the olive production sector, which is increasingly expanding beyond the borders of the Mediterranean basin, harvesting is the most demanding phase, from both an economic and organisational point of view. Traditional olive orchards are still predominant, with centuries-old and large plants, and are characterised by the gradual ripening of drupes and irregular planting patterns. Even though the structural conversion of these olive orchards into more modern cultivations may be difficult owing to their historical, monumental, and landscaping importance, as well as the existing legal restrictions, supporting a "modernisation" process aimed at mechanising the main farming operations remains a priority.

Describing the trend of ammonia, particulate matter and nitrogen oxides: The role of livestock activities in northern Italy during Covid-19 quarantine.

Nitrogen oxides (NOx), sulphur oxides (SOx) and ammonia (NH) are among the main contributors to the formation of secondary particulate matter (PM), which represent a severe risk to human health. Even if important improvements have been achieved worldwide, traffic, industrial activities, and the energy sector are mostly responsible for NOx and SOx release; instead, the agricultural sector is mainly responsible for NH emissions. Due to the emergency of coronavirus disease, in Italy schools and universities have been locked down from late February 2020, followed in March by almost all production and industrial activities as well as road transport, except for the agricultural ones.
