GIS mapping of agricultural plastic waste in southern Europe
AI summary Read the abstract
Researchers used geographic information systems to map the generation and distribution of agricultural plastic waste across four southern European countries: Italy, Spain, Greece, and Portugal. They quantified plastic waste from different farming systems at the regional level and identified hotspots where waste management infrastructure is most needed. The study provides a spatial framework that could help policymakers target plastic waste reduction strategies in agriculture.
The escalating use of plastics in agriculture, driven by global population growth and increasing food demand, has concurrently led to a rise in Agricultural Plastic Waste (APW) production. Effective waste management is imperative, prompting this study to address the initial step of management, that is the quantification and localization of waste generated from different production systems in diverse regions. Focused on four Southern European countries (Italy, Spain, Greece, and Portugal) at the regional level, the study uses Geographic Information System (GIS), land use maps, indices tailored to each specific agricultural application and each crop type for plastic waste mapping. Furthermore, after the data was employed, it was validated by relevant stakeholders of the mentioned countries. The study revealed Spain, particularly the Andalusia region, as the highest contributor to APW equal to 324,000 tons per year, while Portugal's Azores region had the lowest estimate equal to 428 tons per year. Significantly, this research stands out as one of the first to comprehensively consider various plastic applications and detailed crop cultivations within the production systems, representing a pioneering effort in addressing plastic waste management in Southern Europe. This can lead further on to the management of waste in this area and the transfer of the scientific proposition to other countries.

AI summary Read the abstract
Researchers developed a GIS-based methodology using orthophotos and satellite imagery to map and quantify agricultural plastic coverage in the Ionian Coast region of southern Italy, identifying approximately 2,000 hectares of crop protection plastics and locating areas most susceptible to plastic waste accumulation. The open-source GIS framework was designed to be replicable by local authorities as the basis for a regional agricultural plastics atlas.
