Kerosene lamps are vital to many people's lives. But they carry health and economic costs. This is the story of how @berkeleylab.lbl.gov's Dr. Evan Mills, with Blum Center support, helped put off-grid solar on the map: blumcenter.berkeley.edu/how-dr-evan-...

Attention, Cal undergrads interested in understanding and tackling poverty! The Global Poverty & Practice minor is hosting info sessions Sept 25 and Oct 1 on Zoom. The deadline to declare the GPP minor is Oct 14!

Happy World Water Week! We spoke with Development Engineering Prof. Kara Nelson about how water-infrastructure innovations — including producing fertilizer from urine — can combat poverty and address a changing climate: blumcenter.berkeley.edu/world-water-...

Allensworth, CA's groundwater is contaminated by arsenic, but the town has received little help remedying it. So the community teamed up with Development Engineering Prof. Ashok Gadgil to purify its water, with minimal human intervention and affordable costs: www.latimes.com/00000198-77d...

“In this work, compassion isn’t a gesture of service, it’s a radical act of kinship grounded in the belief that there is no us and them, only us." Congrats to the Global Poverty & Practice minor's Class of 2025! blumcenter.berkeley.edu/gpps-class-o...

“We were interested in understanding the role of the household environment in bacterial transmission to humans,” said Prof. @seqh2o.bsky.social. “And our findings showed that water is actually one of the most important transmission pathways for pathogenic and drug-resistant bacteria.”

The goal, Raghuwanshi said, was to “really understand the context & not push your assumptions on people”—not to parachute in & solve problems, “but learn from residents what they want” help with & to be a partner in co-developing community-oriented solutions: blumcenter.berkeley.edu/uc-berkeley-...

Climate change is expected to make sub-Saharan Africa warmer and drier. In @natcomms.nature.com, @seqh2o.bsky.social & co. explore how this affects the burden of collecting water—with impacts for health, hygiene, income, and gender equity: www.nature.com/articles/s41...

Congratulations to Development Engineering Prof. @agogino.bsky.social on winning an inaugural Berkeley Climate Action Proof-of-Concept Award for climate-focused multimodal methane (CH4) sensing! bakarclimate.berkeley.edu/news/uc-berk...

For communities, most policy standards for "modern energy" are a connection to an electrical grid. But in a new paper in Nature Cities, Prof. @dankammen.bsky.social and colleagues show a simple connection does not equal affordable, reliable electricity: www.nature.com/articles/s44...

"If the impact part is missing from a business, it’s not very sustainable.” CarbonSustain — a venture by Paul Bryzek, a 2023 Big Ideas Contest winner — helps small and medium businesses with the onerous work of tracking their carbon emissions: alumni.berkeley.edu/paul-bryzek-...

Ashmita Kumar and Code Blue — her Big Ideas–winning innovation — are piloting her AI-powered in-phone stroke-detection tech with @ucsanfrancisco.bsky.social doctors and are competing this week at the Atlantic Coast Conference InVenture Prize: news.berkeley.edu/2025/03/27/w...

In California Management Review, our board of trustees chair @lauradtyson.bsky.social looks at climate finance and breaks down progress, challenges, and opportunities on the path to Net Zero and a sustainable planet: cmr.berkeley.edu/2025/02/67-2...
