Pedotechnique applications in large-scale farming: Economic value, soil ecosystems services and soil security

subject

description

Abstract Since ancient times Humans and Soil have experienced interwoven links. Nowadays soil scientists continue to stress such links highlighting the importance of soil in: i) satisfying the ever growing Human demand for food, water and energy, and ii) providing ecosystem services that mitigate climate changes, influence human health and improve biodiversity. Pedotechniques are recently used to generate soils suitable for table grape cultivation in order to increase productivity and grape quality, thus to get substantial financial returns. We show one emblematic study case of pedotechniques applied in Sicily (Italy). Aims of the investigation were: i) stressing threats to soil security derived by the generation of anthropogenic soils, ii) assessing the economic sustainability of pedotechniques and table grape production, taking into consideration only the internal factors and excluding the external economic contributions that are allocated to social sustainability and iii) stressing the role of soil science to focus on “economic value” to the soil ecosystem services and degradation processes. Results highlight that soil transformations allow for considerable investment costs. The highest productivity and the consequent higher profitability of the cultivation amortize the start-up costs. From the other side transformations could trigger considerable deterioration of both soil ecosystem services and environmental quality. In order to stress this last aspect and to define the relationships between pedotechnique application and soil security we have considered the five soil security dimensions (i.e. capability, condition, capital, connectivity and codification).
