This panel invites multiple research disciplines and concerned private and public sectors to share evidence and discuss how knowledge of past climate change and past land use by indigenous cultures help us to understand what affects the vegetation and how this information can be used to protect it.
Threats of climate change and expanding human urbanisation makes the future of worldwide vegetation uncertain. Increasing demands of land for the growing global human population adds pressure to people and governments to protect the remaining native vegetation. Nevertheless, are the large efforts of protecting what seems to be the last places of “pristine” vegetation adequate or enough? Understanding the impact of different factors in changing the vegetation is crucial for their protection. Although modelling is becoming a valid methodology to determine the main factors involved in vegetational change, it is still not specific enough to account for individual communities. Specific information of how the vegetation responds to climate change and human impact can be found in palaeoecological, palaeoclimatic and archaeological studies; these studies give us clues to how the vegetation responds to main factors from millennial to centennial time scales. Combining these disciplines we can also help us to understand the role that past human populations had within a specific landscape allow us to evaluate the role that past humans played in shaping the vegetation we see today. Here we propose a discussion amongst archaeologists, palaeoecologists, palaeoeclimatologists, human geographers, anthropologists, policy makers and NGOs to share both evidence and techniques as well to discuss to what extent past cultures and climate modulated the vegetation we see today in areas considered pristine or well preserved. Special emphasis is to evaluate what can be learned about past cultures and their vegetation/landscape use to help land management and conservation today. We expect this discussion to help integrate valuable knowledge and facilitate decision making today in creating, protecting and improving endangered vegetation communities.
