Unveiling the hidden gems: Minor crops as catalysts for sustainable development, biodiversity conservation, and economic resilience

Abstract

This paper highlights the significance of nurturing and safeguarding minor crops as a means of achieving regional sustainable development, preserving biodiversity, and ensuring food security. Minor crops play a critical role in addressing various environmental challenges like climate change, biodiversity loss, desertification, and soil salinity. Simultaneously, they offer local farmers economic opportunities by providing income stability and resilience. To demonstrate the potential of minor crops in promoting sustainable development, a case study from Greece is presented, focusing on three crops: blackcurrant, rice, and sunflower, which bring substantial economic and environmental benefits to the region. The study assesses the economic and environmental impact of these crops across three different rural territories in Greece. Despite covering less than 4% of total agricultural land, these crops are predominantly grown in marginal, mountainous, and insular regions. By analyzing the farm-level and broader economic effects, the study determines their potential for agricultural and regional development. The results indicate that these crops are more profitable and environmentally friendly compared to their counterparts in all three cases. Additionally, they make significant contributions to the regional economies relative to their cultivated land area, supporting economic growth while conserving and enhancing agricultural land. In conclusion, this article emphasizes the crucial need to promote the cultivation and preservation of minor crops to support sustainable development, biodiversity conservation, and regional economic growth. Policymakers and agricultural practitioners should prioritize the cultivation and preservation of regional minor crops to safeguard biodiversity at the regional level and at the same time sustainable regional development.
