The Adoption of Landraces of Durum Wheat in Sicilian Organic Cereal Farming Analysed Using a System Dynamics Approach

Abstract

The adoption of rare, traditional crops represents a good example of enhancing functional agrobiodiversity, not only to provide benefits for farmers but also for society as a whole. The study outlined in this paper aims to verify how and under local social-ecological conditions the combination of organic cereal farming and growing of durum wheat landraces can be profitably applied. Focusing on Sicily as one of the most developed cereal systems existing in southern Italy, the study deployed a comparison between data from the regional dataset by the Farm Accountancy Data Network (FADN) and the data provided by the Association of farmers called Simenza. Thereafter, we used a System Dynamics Approach (SDA) for a better understanding of the main drivers which will most likely affect the profitability of the system in the medium and long term. The results clearly demonstrated how the durum wheat organic system under investigation might still develop under the push of an increasing relative economic advantage between standard varieties and landraces.
