The Impact of Meteorological Conditions and Agricultural Waste Burning on PM Levels: A Case Study of Avellino (Southern Italy).

In this work, the effect of the meteorological conditions and the agricultural waste burning on PM air pollution levels has been investigated in the city of Avellino, located in the Sabato Valley (southern Italy). Avellino has been described among the most polluted towns in Italy in terms of particulate matter (PM) during the last 10 years. The main aim of this study was to analyze the air quality data collected in Avellino and its surroundings during September 2021. In this period, the air quality in the Sabato Valley has been adversely affected by agricultural practices, which represent a significant source of PM. The impact of agricultural waste burning on PM levels in Avellino has been determined through an integrated monitoring network, consisting of two fixed urban reference stations and by several low-cost sensors distributed in the Sabato Valley. In the considered period, the two reference stations recorded several exceedances of the daily average PM10 legislative limit value (50 µg m-3) in addition to high concentrations of PM2.5. Moreover, we provide a detailed description of the event that took place on 25 September 2021, when the combined effect of massive agricultural practices and very stable atmospheric conditions produced a severe pollution episode. Results show PM exceedances in Avellino concurrent with high PM values in the areas bordering the city due to agricultural waste burning and adverse meteorological conditions, which inhibit PM dispersion in the atmosphere.

Valorize to Protect Lucanian Sheep and Goat Biodiversity.

European agriculture and rural development policies have promoted the diversity and genetic types of autochthonous breeds to increase sheep and goat biodiversity. Agri-environmental measures to support livestock farmers, have been the main tools used by these policies over the last twenty years. The COLAUTOC, "Collection of a seed bank for native sheep and goat breeds and strategies to increase their numbers", research project in Basilicata, Southern Italy, investigated sheep and goat farms with autochthonous breeds with results proving a reduction in the number of sheep and goat farms in general, particularly those with native breeds at risk of extinction, a clear indication of policy failure with a devastating loss of sheep and goat biodiversity. The COLAUTOC used a variety of methodological tools, including, desk analysis, focus groups, interviews, school workshops and a survey on sheep and goat meat consumption. The results indicated that a recovery in sheep and goat biodiversity could be achieved by supporting farm livestock strategies with a view to diversify production methods and activities, whilst, recognizing the value added to the territory, landscape, biodiversity and sustainability. The strategies identified by the COLAUTOC project require a local vision, using agri-environmental funds to invest in training on innovation for farms, provide tools to improve the quality of life in the rural areas, to increase communication channels to further knowledge and awareness of biodiversity. These strategies could contribute to meeting several 2030 Agenda goals.
