Current Scenario of Wild Edible Plants (WEPs), their Importance, Possible Threats, and Conservation: A Mini Review

Abstract

The knowledge of Wild Edible Plants (WEPs) is as old as human civilization and still, they are playing a supplementary role in global food security. WEPs are an integral part of their traditional food systems and have nutritional and cultural values in their routine livelihood. WEPs are increasingly considered a potential source of a naturally healthy diet. But in many cases, the available WEPs resources are under threat of various kinds like overexploitation, overgrazing, forest fires, agricultural encroachment, etc.; the changing climate also negatively impacts on WEPs. Therefore, there is an urgent need for the conservation of the diversity of WEPs and their sustainable management. The present mini-review is an attempt to present the current scenario of WEPs, their importance, and a potential source of nutrients for future food security, ethnic knowledge associated with them, threats encountered by WEPs, and their possible sustainable management scheme.
