Bridging Traditional Knowledge and Satellite Images in Bolivia
From Regional Environmental Change: “In the Andes, indigenous pastoral communities are confronting new challenges in managing mountain peatland pastures, locally called bofedales. Assessing land cover change using satellite images, vegetation survey, and local knowledge (i.e., traditional ecological knowledge) reveals the multi-faceted socio-ecological dimensions of bofedal change in Sajama National Park (PNS), Bolivia. Here, we present results from focus groups held in 2016 and 2017 to learn about the local knowledge of bofedales in five Aymara communities in PNS. Land cover maps, created from Landsat satellite imagery, provided a baseline reference of the decadal change of bofedales (1986, 1996, 2006, and 2016) and were field verified with vegetation sampling. At the park level, the land cover maps show a reduction of healthy bofedales (i.e., Juncaceae dominated peatland) cover from 33.8 km2 in 1986 to 21.7 km2 in 2016, and an increase in dry mixed grasses (e.g., Poaceae dominated land cover) from 5.1 km2 (1986) to 20.3 km2 (2016). Locals identify climate change, lack of irrigation, difficulty in water access, and loss of communal water management practices as key bofedal management challenges. Local improvement of bofedales was found in one community due to community-based irrigation efforts. Bridging knowledge of mountain land cover change helps to articulate the socio-ecological dimensions that influence local decision-making regarding bofedal management, and consideration of local actions that may be strengthened to support the sustainability of bofedales for local livelihoods in the context of climate change in the Andes.”
Pleistocene and Holocene Cirque Glaciation in the Western United States
From Nature: “Our [glacier chronology] demonstrates that each of the moraines originally interpreted as Neoglacial was deposited during the latest Pleistocene to earliest Holocene (between ~15 and 9 ka), indicating that, with the exception of some isolated locations, cirque glaciers in the western U.S. did not extend beyond their LIA limits during much, if not all, of the Holocene.”
Jackson Heights, Queens Honors Nepal
“One community is celebrating a new addition to the Jackson Heights neighborhood that honors their native country.
Council Member Costa Constantinides joined New Yorker’s from Nepal for a co-naming ceremony at the intersection at 75th Street and 31st Avenue on Saturday.
That area will now be known as ‘Mount Everest Way.’
The co-naming was approved by the City Council back in December.
Thousands of New Yorkers with ties to Nepal traveled from all five boroughs to celebrate the occasion.
‘We’ve been here for a while now and lots of respectful people live around here so I’m happy they’re doing it now, like later but like it’s finally happening,’ said Lochana Subedi, a native of Nepal.
The city estimates that there are about 10,000 people from Nepal living in the 5 boroughs.”
