Domestication of new plants is one of the key (ongoing) phenomena in the history of agriculture. Wild plants are the ancestors of current and future crops and the largest reservoir of genetic diversity for crop breeding and improvement. Wild food species have been used for human nutrition since ancient times and are often the object of human strategies for coping with emergency situations, such as natural disasters and conflicts. We analyzed qualitative data collected through ethnobotanical field studies conducted in recent years in five selected Eurasian regions (Afghanistan, Kurdistan region of Iraq, Pakistan, Syria, and Ukraine) that have been recently affected by wars and/or socio-political turbulence. Data were collected through participant observation and semi-structured interviews with local people. We identified five taxa for each region, which are culturally very salient in the local food systems, that retain an important economic value in local markets, and that, therefore, could be good candidates for becoming novel crops. The cultivation of the reported species may significantly help local communities in their post-war livelihoods and especially in terms of food security and domestic nutritional care. Future studies should focus on the agronomic feasibility of the highlighted species within their regional ecosystems.

The study of migrants’ ethnobotany can help to address the diverse socio-ecological factors affecting temporal and spatial changes in local ecological knowledge (LEK). Through semi-structured and in-depth conversations with ninety interviewees among local Pathans and Afghan refugees in Kohat District, NW Pakistan, one hundred and forty-five wild plant and mushroom folk taxa were recorded. The plants quoted by Afghan refugees living inside and outside the camps tend to converge, while the Afghan data showed significant differences with those collected by local Pakistani Pathans. Interviewees mentioned two main driving factors potentially eroding folk plant knowledge: (a) recent stricter border policies have made it more difficult for refugees to visit their home regions in Afghanistan and therefore to also procure plants in their native country; (b) their disadvantaged economic conditions have forced them to engage more and more in urban activities in the host country, leaving little time for farming and foraging practices. Stakeholders should foster the exposure that refugee communities have to their plant resources, try to increase their socio-economic status, and facilitate both their settling outside the camps and their transnational movement for enhancing their use of wild plants, ultimately leading to improvements in their food security and health status.
