Foraging for Local Wild Edible Plants (WEPs) in Finland and Tenerife, Biodiversity, Food Systems, and Sustainable Development

The paper describes a new research approach to sustainability research: qualitative meta-research. The researcher is the main research instrument. He designs research questions, seek answers for them, reflects and evaluates the research. This in important when making observations in nature, about plants and their development, and building natural historical knowledge on own observations about Wild Edible Plants (WEPs). I live about six months in Helsinki (from April October) and six months in Puerto de la Cruz (from November to the end of March). I forage in both localities. That is why, I can write about WEPs in both areas. I used academic search engines like Google Scholar to find relevant research on Wild Edible Plants (WEPs) from Popper's WORLD 3 (cultural objects). I found a couple of useful new sources to me. I used also Copilot Artificial Intelligence. I checked the quality of the answers using other tools. Because the researcher is an established researcher in WEPs research, both Google Scholar and Copilot Artificial Intelligence found his works as the best sources to WEPs in both localities. The new feature in the qualitative meta-research is to use auditing to check the quality of research. Auditing improves credibility and trustworthiness.
