“Donald Trump has ordered that swathes of America’s forests be felled for timber,

evading rules to protect endangered species while doing so

and raising the prospect of chainsaws razing some of the most ecologically important trees in the US.”

"Across Canada and the U.S., a growing number of shuttered #golf courses are being rewilded.

"At least four courses in California, and a handful of others in the U.S., U.K. and Australia, have been bought by non-profits, cities or land trusts and turned into #nature preserves or #parks in recent years, leading to an increase in #wildlife sightings, plant species and tree cover."

Dearest Fediverse (and apologies for the absence),

my book "Hard Work: Producing places, relations and value on a Papua New Guinea resource frontier" was just recently published in full digital open access. (Print-on-demand and oa epub out soon!)

hup.fi/site/books/m/10.33134/H

"Hard Work explores the complexities of natural resource extraction, looking at both large-scale processes and personal human-environment interactions. It combines a political ecology focus on the connection between environmental issues and power relations with a focus on how value is produced, represented, and materialized."

Cover of the book "Hard Work". The cover is a photograph showing a foggy tropical river valley. On the foreground on the left stands a Papua New Guinean woman with her back to the camera holding a food basket on her head and walking staff in her right hand looking at the valley. The woman stands in tropical garden and in front of her are banana plants. On right, a bit further from the camera is a tall tree standing in the garden. In the background are forested mountain slopes. On the top of the cover is the name of the author, "Tuomas Tammisto". Below it is the title of the book: "Hard Work: Producing places, relations and value on a Papua New Guinea resource frontier". On the bottom left is the name of the publisher: "HUP Helsinki University Press".

photo - A researcher moves through the Great Dismal Swamp in Virginia.
Schematic - ash mass concept. For a column of peat exposed to drainage, the surface peat is exposed to more oxidation and therefore carbon is lost but the ash content is conserved. This demonstrates how carbon loss can be calculated using the remaining ash in the peat column. The terms correspond to the terms in Equations 1-5, with r = reference layer and i = impacted layer. The dashed line in the second column indicates the loss. The loss in thickness due to shallow subsidence results from the difference in the bulk densities, whereas the secondary subsidence results from the loss in elevation due to oxidation, driven by the differences in ash mass.
Maps - coring locations, ditches by age, dominant vegetation communities. Contours correspond to estimated peat depths based on Oaks and Whitehead (1979). Coring locations are indicated by the following numbers: 1. GDS519, 2. GDS520, 3. GDSW1, 4. GDS77, 5. GDS83, 6. GDS528, 7. Interior-South, 8. Interior-North, 9. GDS96, 10. GDS-P + H, 11. GDS542, 12. GDS-04-14-2022-1A, 13. GDS-04-14-2022-1B. (a) Map of Great Dismal Swamp National Wildlife Refuge (GDS NWR) showing coring locations and binned ages of ditch, canal, and railroad installation, (b) Map of GDS NWR showing dominant vegetation communities within GDS NWR. The “early successional” (marsh) area to the southeast of Lake Drummond corresponds to the area burned in both 2008 and 2011. The area bounded by shading represents the Great Dismal Swamp NWR boundary.
charts - Carbon stocks and accumulation at GDS sites. (a) Carbon stocks for all sites, including two calculations for heavily impacted sites (GDS-W1, GDS-77, and GDS-P&H). Stars indicate calculations from ash mass from the lower depths of each of those cores, while the other (b) calculation for these sites indicates the lower ash mass calculation using the average of other less disturbed sites. Burn scar cores calculations are down to the first charcoal peak (a) and down to the second peak (b) for GDS-Interior-North and South. (b) Carbon accumulation and loss rates for cores with vegetation reconstructions. Negative values indicate carbon loss values.

Those readers know few topics rile my sense of conscience the way capitalism and real estate speculation can. Selig’s ruthless gambler persona persuaded powerful Seattle business oriented politicians and media through zoning and other tax breaks to embrace the promise of commercial development over much needed housing. Now he defaults on $240M loan. It’s gambling and white collars can’t cover the criminality. 1/3 #capitalism #realestate #landuse #sharingeconomy seattletimes.com/business/deve

Plant-based #diets can have a big impact on #landuse. If Romania's population moved to a #plantbased diet, this could free 75% of the #agriculture land for other uses, reduce GHG #emissions & pressure on #ecosystems, and promote #sustainability goals: sciforum.net/paper/view/18586

sciforum.netSciforum : Event management platformIntroduction In Romania, adopting a plant-based diet could have a profound impact on agricultural land use, reflecting broader global trends. This study investigates the potential land savings by analyzing the land required to produce various sources of calories. The focus is on understanding how a shift in dietary habits could contribute to more sustainable land use, environmental conservation, and the achievement of Sustainable Development Goal (SDG) 12, which aims to ensure sustainable consumption and production patterns. Methods The research employs data from governmental sources (Romanian Ministry of Agriculture), and international reports from organizations (FAO). It examines the land-use efficiency of different foods, comparing meat, dairy, grains, and legumes. The analysis involves calculating the land required per calorie produced and extrapolating these findings to model the impact of a nationwide dietary shift. Results Preliminary findings indicate that plant-based foods, such as grains and legumes, require significantly less land per calorie compared to animal-based products. For example, producing one calorie from beef requires substantially more land than producing the same amount of calories from beans. If Romania's adult population transitioned to a plant-based diet, the potential reduction in agricultural land use could be as high as 75%. This transition would not only free up land for other uses but also reduce the pressure on natural ecosystems and lower greenhouse gas emissions from agricultural activities. Conclusions Transitioning to a plant-based diet among Romania's adult population presents an opportunity for substantial agricultural land savings and environmental benefits. Such a dietary shift would support the conservation of natural resources and contribute to national and global sustainability goals. Moreover, the proposed model can be applied to other countries, providing a scalable solution to reduce agricultural land use worldwide. Efforts must coordinate to educate the public on plant-based diet benefits and develop policies for sustainable agriculture.

The "two-legged" climate model

“The idea was that both greenhouse gases and #LandUse contribute to #ClimateChange, but at different rates,” writes Millan. “Land-use changes the hydrologic cycle immediately, at a small or larger scale, depending on the perturbation. Greenhouse gases are already there,” meaning they spread out globally and don’t change day to day. He speaks of “two rates of climate interaction and two basic mechanisms.”
