Monitoring pesticide use is essential for assessing farming practices and the risks associated with the use of pesticides. Currently, there are neither consolidated, public data available on glyphosate use in Europe, nor a standardized categorization of its major uses. In this study, data on glyphosate sales and use in Europe were collected from multiple sources and compiled into a dataset of the agricultural use of glyphosate from 2013 to 2017. The survey shows that glyphosate represented 33% of the herbicide volume sold in Europe in 2017. One third of the acreage of annual cropping systems and half of the acreage of perennial tree crops received glyphosate annually. Glyphosate is widely used for at least eight agronomic purposes, including weed control, crop desiccation, terminating cover crops, terminating temporary grassland and renewing permanent grassland. Glyphosate use can be classified into occasional uses—i.e., exceptional applications, triggered by meteorological conditions or specific farm constraints—and recurrent uses, which are widespread practices that are embedded in farming systems and for which other agronomic solutions may exist but are not frequently used. This article proposes a framework for the precise monitoring of glyphosate use, based on the identification of the cropping systems in which glyphosate is used, the agronomic purposes for which it is employed, the dose used and the rationale behind the different uses.

Although hemp cultivation is increasingly perceived as a promising option in terms of crop diversification, especially in semi-arid conditions such as in the Mediterranean region, its adoption remains limited thus constraining the development of hemp value chains at a larger scale. Our objective was to explore suitable conditions, at farm and downstream levels, for organic hempseed oil production in Sicily, taking on an action-research perspective that involves local actors. Based on a preliminary characterisation of barriers to organic hemp development at different value chain levels, we carried out targeted complementary investigation: (i) assessment on agroenvironmental performances of integrating hemp in durum wheat-based rotations; (ii) chemical analysis of local hempseed oil; (iii) exploration of marketing opportunities and value chain development. Our results showed that the lack of technical and economic knowledge as well as the deficiencies of suitable cultivars and adequate machinery were the main barriers for the organic hemp value chain development in Sicily. The analysis of agroenvironmental performances also revealed both strengths and weaknesses of hemp introduction in durum-wheat based rotations. Despite the identified limitations, we demonstrated that the organic hemp value chains represent interesting perspectives for the Sicilian farming sector, particularly in case of substantial barriers removal or adaptation.
