The study—led by affiliate researchers in the UH Hilo College of Agriculture, Forestry, and Natural Resource Management—creates a new, combined process to remove carbon dioxide (CO2) from the atmosphere, produce food and electricity, and reduce deforestation.

Researchers from the University of Hawaiʻi at Hilo, in affiliation with Duke and Cornell universities, have co-authored a study that suggests making croplands more efficient through algae production could unlock an important negative emission technology to combat climate change.

The research, “Integrating Algae with Bioenergy Carbon Capture and Storage (ABECCS) Increases Sustainability,” is funded by a U.S. Department of Energy award and was recently published in the journal Earth’s Future. This funding is a Marine Algae Industrialization Consortium (MAGIC) grant for which Bruce Mathews, dean of the UH Hilo College of Agriculture, Forestry and Natural Resource Management (CAFNRM), serves as the facilitating principal investigator at UH Hilo. Duke University subcontracted the overall project out to multiple institutions, including UH Hilo.

Students reps come from all 10 campuses of the UH System, and each will be coordinating local action projects on their home island. Alexis Stubbs represents UH Hilo.

Last month held opportunity for a student sustainability representative from each University of Hawai‘i campus (10 campuses, six islands) to join and collaborate on student sustainability driven initiatives in preparation for the upcoming World Youth Congress (WYC) to be held in Hawai‘i this coming summer.

The UH Hilo representative is Alexis Stubbs, a sophomore specializing in tropical horticulture at the College of Agriculture, Forestry and Natural Resource Management.

To prepare for next year’s congress, a three-day retreat was held Nov. 11-13 at Camp Pālehua in Kapolei, O‘ahu. The retreat was titled Aha Ho‘owaiwai (A Whole Community Approach to Wellness) and aimed to reflect the strength of coming together, sharing and caring as a community all in preparation of the Makahiki season. Community from the entire Hawaiian archipelago were present.

We spent time this summer in China collecting and testing soil samples for a study about the long-term effects that warming and nitrogen addition would have on microbial composition and enzyme production.

At the Sanming Forest Ecosystem and Global Change Research Station in Fujian, China, scientists and researchers from various fields gather to utilize experimental plots designed as mesocosm studies and in-field sampling and monitoring stations to study forest hydrological change, forest carbon management, and future global change.
