Boston’s Food Forests Take Root as a Climate Equity Strategy - Inside Climate News A decade of organizing has turned trash-strewn lots into edible parks. Now Boston is expanding food forests as part of its climate action plan.

🌱 Boston is turning vacant lots into edible forests, integrating food, nature, and community right into the city fabric. Urban climate justice in action. Shout out to @mayorwu.boston.gov for all of her great work! 🍓🌳

Drought intensity and duration interact to magnify losses in primary productivity As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with cons...

The latest DroughtNet paper is out in Science today! Using coordinated experiments across six continents and 74 sites, the International Drought Experiment found differences between the effects of extreme droughts and more typical droughts... (1/3) www.science.org/doi/10.1126/...

Very cool initiative training citizens/residents in tree pruning & stewardship 🌳 Wonder if something like this will catch on here in Canada 🇨🇦

Field trip day! 🌳 Our Urban Forestry course is out in the field …Dominic, a master’s student in the lab, is leading a session on #tree plantation pits at our living lab site, where we’re testing 9 structural pit designs with the city. #UrbanForestry #FieldLearning #urbanforests

Infographic detailing seven ways to create a bird-friendly community, including planting native plants, turning off lights, avoiding pesticides, and preventing collisions.

Urban expansion can lead to habitat loss. Yet, as IPBES #GlobalAssessment shows, smart city planning + nature-based solutions can create resilient, bird-friendly cities.🌍

This #WorldMigratoryBirdDay, let’s protect migratory birds in our #SharedSpaces 🏡

Savannah Bissegger O’Connor, Dominic Bartolacci et Ravosoa Ramaroson de la Chaire de recherche sur l’arbre urbain et son milieu présenteront leurs travaux au Rendez-vous #arboricole 🌳

In a survey conducted by the Mental Health Foundation, 70% of adults agreed that being close to nature improves their mood.

Bringing nature closer to home by sponsoring a street tree feels like the ideal way to observe Mental Health Day this year, don't you think?

Land tenure (in) security in the context of urban flood risk in Ghana The increasing incidence of floods driven by urbanization and climate change destabilizes urban social, economic and environmental systems where land …

A new paper out in Land Use Policy - “Land tenure (in)security in the context of urban flood risk in Ghana.”

We show that flood risk management through post-flood land use planning has potential to have dual impacts on community resilience and tenure security.

My number one tip for researchers that do a significant amount of non peer reviewed paper publication/outreach:

Create an excel table, every time you give an interview, talk, write an oped or white paper, etc. take 5 seconds to immediately note it in the excel.

Loved spending the summer with the @jananisivarajah.bsky.social lab and @ffgg-ulaval.bsky.social. Lots of new projects on the horizon, and great to learn from another lab group.

Next up, a quick visit to U-Windsor!

Cities Vs. Climate Change: Global Exhibition In Paris Inspires Action From Paris to Belém: 10 Years of Global Climate Action—celebrates a decade of bold urban responses to climate change since the 2015 Paris Agreement.

ICYMI: “Paris is uniquely positioned to celebrate & platform bold action from cities all over the world…really exemplifying those key words ‘further & faster.’ Not because they’ve been perfect but because they’ve been strategic, determined, & fearless.” My @forbes.com interview with @carltonreid.com
