Building sustainability science on solid ground: our framework uses shared social-ecological units to integrate diverse data streams. Tested in Rwanda, adaptable elsewhere. Open, reproducible, and ready for interdisciplinary teams. #Rwanda #Restoration @biogeoberlin.bsky.social shorturl.at/qHaQ0

Southeast Asia covers multiple global biodiversity hotspots — but is experiencing a biodiversity crisis.

Our new article in Nature Reviews Biodiversity asks: What’s really driving the losses, and what can we do about it?

Drivers and solutions to Southeast Asia’s biodiversity crisis

After a long absence from Twitter, I'm now on Bluesky. Looking forward to sharing thoughts, research, and rants about the lack of attention paid to water. Let's kick this off with a new paper alert. Please share widely. Title says it all. Please help me grow followers www.science.org/doi/10.1126/...
Unprecedented continental drying, shrinking freshwater availability, and increasing land contributions to sea level rise
Drying continents, extreme drought, and groundwater depletion are shrinking water availability and increasing sea level rise.

Drawing on data from over 400 forest plantations in Himachal Pradesh, India, we show that improved forest outcomes (increasing forest cover, improved forest-based livelihoods) are strongly associated with long-term participation by local people in decision-making. iopscience.iop.org/article/10.1...

The biggest publishers pulled profit margins in 2023 that rival Big Tech.

And they still charge you to publish and your library to read.

When are we going to start seriously thinking of alternatives to reform #PeerReview?

Where is the money going? In the case of for-profit publishers it's very clear:

Your open access fees fund corporate profit margins.

Profit margins for large academic publishers can far exceed those of household names like Amazon and Apple.

chart source: bit.ly/4leULKi
#scipub #academicsky
Chart shows profit margin for Elsevier is 38%, for Springer-Nature is 27%... this is in comparison to companies like Apple (25%), Amazon (5%)... There are non-publishing companies like Microsoft with big margins (34%), but overall the chart shows that academic publishing companies have surprisingly large profits when compared to more "famous" large companies that are household names.

2. Six Woodland Change Archetypes: six distinct patterns — three reflecting continuous woodland decline and three showing a forest transition trajectory, revealing strong regional variation in woodland dynamics.

3. Woodland Cover Strongly Linked to Threatened megafauna species.
tamannakalam.bsky.social
Here, we reconstructed #tropicaldrywoodland change since the 19th century, identified #archetypes of change, and explored their relationship with current megafauna distributions.

Findings:

1. Massive Historical Loss: India has lost over 22 million hectares of dry woodland since the 19th century.

The Accelerating Exposure of European #ProtectedAreas to #ClimateChange

We measure climate velocity and magnitude in Europe, and estimate risk for #ProtectedAreas and species.

Paper and maps available OA
doi.org/10.1111/gcb.... @martacimatti.bsky.social
Overlay of the values within the last quartile (higher values) from each climate risk metric for scenario SSP3-7.0. Areas in the map are color-coded based on their overlap with hotspots of exposure identified based on different climate metrics (Local, local velocity; Analog, analog velocity; Magnitude). Areas with no analogues within the 1500 km search radius (NA values on land) are shown as blank spots (i.e. central Greenland). Map lines delineate study areas and do not necessarily depict accepted national boundaries.

Excellent article covering a new systematic review of restoration in the Western Himalayas. Concerning findings, similar to my work, are that restoration has tended to focus on (not very successful) tree plantations on govt. land, with overuse of exotic species: india.mongabay.com/2025/05/unpa...

The first roads that slice through rainforests are widely recognized as pathways for #deforestation. However, new research reveals that secondary roads—those branching off from main roads—are responsible for significantly greater forest loss than the primary roads themselves.

Secondary roads cause more deforestation than primary roads in tropical forests
The first roads that cut through rainforests are well-known conduits for deforestation. However, new research finds that secondary roads, those that branch off the primary road, cause far more forest ...

New paper! India's #agriculture-#savanna mosaics are changing: less traditional crops, more sugarcane. Led by @tejasconsbio.bsky.social, we studied implications for birds - those resident in India, but also steppe birds arriving from Kazakhstan such as Pallid Harrier and Sociable Lapwing.

How can AI for #EarthObservation deliver for social good? Read our recent #openaccess IEEE Geoscience and Remote Sensing Magazine article, co-authored by @hostertp.bsky.social and @philrufin.bsky.social!

New #IEEE GRSM paper on responsible #AI for #EarthObservation! AI for EO data analysis holds great promise in addressing global challenges but simultaneously needs a careful examination of the dimensions of responsibility. We reviewed them in this #openaccess article: doi.org/10.1109/MGRS...
Diagram showing the main building blocks of responsible
AI in EO. Mitigating unfair bias, securing AI, preserving (geo)privacy, and addressing ethical concerns outline the considerations necessary for
implementing responsible AI methodologies within the fields of EO.
Social good presents the opportunities and goals related to how a
responsible AI system can effectively be utilized to make a positive
difference in people’s lives.

This tigress has reclaimed the ancient fort within Bandhavgarh Tiger Reserve and made it her home.

Protection, prey, peace, and prosperity have been key factors in the tiger recovery within India, according to a new Science study. Learn more in this week's issue: https://scim.ag/42yn5Ra
Cultural reverence toward tigers (Panthera tigris) has fostered tolerance and permitted coexistence with humans in India. Ecological restoration, socioeconomic policies, and political stability have facilitated the recovery of tigers within their historical range, despite high human densities. This tigress has reclaimed the ancient fort within Bandhavgarh Tiger Reserve and made it her home.
