#Mining sub-Saharan Africa is expanding rapidly. This poses a key threat to tropical forests.

"For every hectare of direct deforestation due to the mine footprint, mining triggers, on average, 34 hectares of additional offsite loss within five years through ancillary activities, including agriculture and settlements. Mines extracting cobalt and copper—key energy transition minerals—caused the highest amount of additional deforestation."

Morton et al. (2026). "Mining triggers extensive additional deforestation in sub-Saharan Africa" https://doi.org/10.1038/s41586-026-10551-2 🧩 🧵

While we are NOT on the subject of #ClimateChange, #Sealevelrise & #subsidence, here is a series of maps & aerials showing the progression of #landloss associated with Grande Terre Island at the lower end of Barataria Bay, LA, we've used in various reports. We finished work at Grande Terre in 2021. #archaeology

"Assuming all #renewable [#energy] development locates on [some of #Alberta's best] land, the percentage of [such] #agricultural #landloss is estimated to be less than one per cent by 2041," says the #AlbertaUtilitiesCommission report, released Wednesday. "From 2019 to 2021, the largest driver of agricultural land loss was expansion of #pipelines and #industrial sites. Other key drivers… include #urban #residential #development, #mines and #wells, and #roads." #abpoli

1998, 2005, 2015 & 2020 aerials of the same area. In 2005 the 2 isles were underwater shoals. In 2015 they were sand bars. In 2020 only 1 remained. Looking at their progression, they might not reform. #landloss #Louisiana

I don't remember if I posted this.

USGS quad maps of barrier island Grand Gosier Island 1951 & 1988 when it was Islands. Part of the Chandeleur Island chain, remnants of a 2000-year-old delta front. #geology #Landloss #Louisiana

#Louisiana ’s newly released #draft of the state’s 2023 #CoastalMasterPlan proposes to spend $16 billion on construction new #TidalMarshes as a key #strategy to #combat #coastal #LandLoss.
A new study published in journal #Ecosphere & funded by the #NOAA RESTORE #Science Program addresses this issue, and the results provide #PositiveNews for the state’s plans to #rebuild the #coastline .
