🏘️ How do we make locally led adaptation (LLA) successful? A new report from SEI and partners shows that LLA is effective, but to unlock finance flows we should: 👫 Put local actors in the lead ✅ Recognize wide-ranging benefits 💰️ Make funding, research and evaluation more flexible 🔗 buff.ly/KvA6ptK

SEI's Lisa Dellmuth and Nicolas Rost of the UN Central Emergency Response Fund (CERF) have found that donors "crowd in" to fund humanitarian crises, once established funders like CERF are on board. They suggest CERF and other pooled funds can signal where funding needs to go: buff.ly/lWKevGD.

Pooled funds catalyse funding
New research on the Central Emergency Response Fund (CERF) finds that bilateral donors often allocate more humanitarian funding to countries after CERF support.

Shoring up infrastructure can help competitiveness, while improving compliance monitoring of mining activities can support environmental and social conditions at mines and the greater communities.
Photo shows yellow trucks cris-crossing a brown and gray open pit manganese mine in South Africa's North West province. Text below reads: "3. Infrastructure, enforcement and implementation gaps can limit the potential for regional value creation. Ongoing obstacles such as unreliable power supply, environmental monitoring gaps and uneven implementation of development agreements can constrain the benefits of local mineral processing."

Simplifying existing regional trade agreements can reduce inefficiencies and unlock more intra-African critical mineral trade.
A photo shows piles of gray ore rock being moved for storage on a conveyor belt at a platinum mining site in South Africa. Text below reads: "2. Effective implementation of the AfCFTA could boost regional critical materials value chains. Harmonizing trade approaches and policies across overlapping regional arrangements under the African Continental Free Trade area could create clearer pathways for cross-border value chains."

Reducing reliance on raw mineral exports is important as African countries seek to capture more value from their mineral deposits.
Piles of brown, gray and white soil samples are arranged in a grid on the ground in South Africa, intended to allow identification of metals and mineral concentrations for possible mining. Text below the image reads: "1. Local value creation in mining can help support equitable growth and regional economic integration. When supported by robust environmental and social governance, local value creation measures, including mineral processing, can advance sustainable, inclusive growth."

Washington nears final step in joining California-Quebec carbon market • Washington State Standard
California Gov. Gavin Newsom announced his authorization to move forward with linking Washington into its carbon market that’s shared with Quebec, Canada.

Stockholm Environment Institute @sei.org · 24/09/2026
The governors of California and Washington announced at #ClimateWeekNYC a deal that brings Washington into the California–Québec #CarbonMarket in 2027. SEI expert Derik Broekhoff lauds the move, saying it will bring savings to energy customers and help cut planet-warming emissions.
Blue graphic shows a photo of a smiling Derik Broekhoff, Senior Scientist at SEI US, along with a quote of his that reads: "The linkage will help alleviate costs for Washingtonians, and by joining forces with California and Québec, we help forge an even bigger, multi-jurisdiction approach to driving down greenhouse gas emissions – one with political and institutional staying power, and a model for other states and provinces."

From footnote to main course: why mussels, oysters and clams belong in One Health food systems
Aquatic foods are largely overlooked global food system transformation discussions. SEI experts argue that bivalves in particular should take centre stage.
000
Stockholm Environment Institute @sei.org · 23/09/2026
Not least: Bivalves actually clean their surrounding environment.
100
Stockholm Environment Institute @sei.org · 23/09/2026
Secondly: These species deliver comparable nutritional value to many other common animal proteins.
100
Stockholm Environment Institute @sei.org · 23/09/2026
One reason: Bivalves do not require many of the valuable resources other animals and crops require to survive and thrive.

Stockholm Environment Institute @sei.org · 23/09/2026
As @fao.org convenes decision-makers and experts on spurring implementation of #OneHealth principles in global #FoodSystems, SEI experts argue for the elevation of bivalves – mussels, clams and oysters – in such conversations. Their new perspective details why. 👀
