摘要：In light of the current interest in climate change and its effects onmodern economies, several projects have highlighted the role of climateforcing on past societies. In particular, there has been focus onthe role of climate forcing in the Iberian Peninsula, during the 4.2 kevent, which roughly coincides with the Chalcolithic to Bronze Agetransition (c. 2200 – 2000 BCE).While much of this research has focused on the South-eastern regions,given its long and rich history of archaeological research, someattention has shifted to the Southwest Iberia, which has revealed inrecent years a clearer picture of its societies during the Chalcolithicperiod. More specifically, Southwest Iberia has disclosed very interestingsocial dynamics when it comes to ditched-enclosure sites,dynamics that came to a rather abrupt end around the same time ofthe 4.2 k event. The current paper reports the results of the 2018 geomagneticsurvey campaign at the ditched-enclosure site of Monte daContenda, in Arronches, Portugal. While these results are not directlyrelated to climate forcing per se, they do provide more insight intothe Chalcolithic communities that could have been directly affectedby climate events.Whereas the first campaign, in 2013, revealed a very complex ditchsystem but was unable to expose the site’s full layout, the 2018 campaignwas able to reveal the site’s ditch systems in their entirety.Many of the assumptions established in the first campaign concerningthe layout of the site were confirmed during this second campaign,namely that the ditch system is delimited to the south by theribeira das Argamassas and that the site contains two distinct ditchsystems, comprising a total of 17 to 19 ditches, establishing Monteda Contenda as the site with the highest number of ditches currentlyknown in Portugal.
