The INQUA-funded multi-year #pSESYNTH project envisions the first multi-disciplinary #Holocene paleo #database through a collective vision for past #SocialEcologicalSystems in the #GlobalSouth, and their future sustainability.

We describe #pSESYNTH, an example of scientific community mobilization & collaboration focused on the #GlobalSouth, i.e. Latin America & the Caribbean, Africa, Asia, & parts of Oceania where researchers have been historically marginalized from international collaborations. (3/n) 
1/Hi all! This afternoon we look (selectively) at what pollen records, tell us about long term changes, from the end of the last Glaciation. How has climate, humans+related processes shaped the 🇮🇪 vegetation over thousands of years? (Nick Miller, From Cogan's Shed, 2004)
2/Difficult to summarise 1000s yrs in tweets! Image by Gill Plunkett @QUBelfast does good jobNB. highly generalised, much spatial variation across country; Key points: development of woodland as climate warms start of #Holocene hazel dominant, oak, elm, later alder, how dense?
3/Closed canopy? But NB1 Concept of 'Climax' woodland largely discredited; : 'openess' is under-represented in #pollen records! NB2; #ClimateChange driving some changes; other processes inc. soil development. When does human activity impact? Now that's a good qu!
Though I am really glad that #arsenic contamination of #groundwater in India, and specially #WestBengal is getting the attention it deserves, there is a major issue that needs wider discussion.
There is a simplistic argument that arsenic naturally occurs in the #Gangetic belt, the author uses the term “#geological curse”. If this is the case, why is heavy #arsenic contamination being reported from #Jharkhand and #Chattisgarh in Central India?
A possible answer to that may be traced to this MIT paper that was published in @NatureGeosci on #anthropogenic influence on #groundwater #arsenic contamination in #Bangladesh nature.com/articles/ngeo6…
