Abstract
By 2050, the increasing demand for food will put additional pressure on natural resources. Underutilized crops, such as wild vegetables, are an essential component of the Mediterranean diet and are widely correlated with the traditional cuisine of Mediterranean countries. They could be widely associated with resistance to abiotic stress and enhanced genetic diversity, and could provide various ecosystem services. Their cultivation could support the Sustainable Development Goals (SDGs) established by the UN and the current EU policies related to environmentally friendly agriculture. Based on an extensive literature review, the aim of this paper is to summarize the environmental and ecological requirements of specific Mediterranean underutilized vegetables, the provisioning and regulating ecosystem services that could be derived from their cultivation, and their potential use. It is concluded that thorough planning of underutilized crop cultivation could enhance the provisioning and regulating ecosystem services that positively affect Mediterranean agriculture. However, further research should be carried out regarding their environmental and economic impact in order to assess the environmental and socio-economic effects of underutilized crops cultivation. This could lead to designing future policies that support underutilized crop cultivation and consumption.
