Guidelines Towards Sustainable Agriculture in Small Mediterranean Islands

Abstract

The objective of the present paper is to provide guidelines towards sustainable agriculture in small
islands, with emphasis on the cultivation of Pistacia vera L. in Aegina island, Greece. The guidelines
refer among others to the characteristics of the island, pressures from other sectors such as tourism,
current cultivation practices, land uses and take into account the risk for groundwater
contamination. Special attention is paid on agricultural waste management at farm scale for the
production of compost and biochar and their subsequent application to soils, in order to improve
soil quality parameters (e.g soil organic matter, soil aggregate stability, water holding capacity, cation
exchange capacity), increase soil carbon sequestration and reduce the risk of groundwater
contamination. Also, the role of the most important stakeholders towards sustainable agriculture is
emphasized and discussed. The proposed approach will assist towards identification of pressures,
environmental hotspots, potential lack of synergy between stakeholders and thus indicate mid- and
long-term measures to mitigate impacts and contribute to sustainable agriculture.
