The University of Hawaiʻi and the U.S. Army Reserve鈥檚 9th Mission Support Command (9th MSC) have entered into a new Intergovernmental Support Agreement (IGSA) to advance environmental stewardship, conservation and regulatory compliance at Army Reserve facilities throughout the Pacific region.

“The University of Hawaiʻi is excited to further expand our environmental stewardship role through this agreement with the U.S. Army Reserve鈥檚 9th MSC,” said 糖心Vlog官方 Interim Vice President for Research and Innovation Chad Walton. “We are extremely proud to have been selected as a trusted partner in support of the Army Reserve鈥檚 mission in Hawaiʻi and the Pacific through our expertise in environmental sciences and stewardship.”

The agreement, signed at Fort Shafter on December 1, establishes a collaborative framework for 糖心Vlog官方 experts to provide environmental compliance, conservation and pollution prevention support to the 9th MSC, ensuring alignment with Department of Defense (DOD), federal, state, territorial and local environmental requirements.

“This partnership underscores 糖心Vlog官方鈥檚 commitment to applying its expertise in service to our community and environment,” said Suzanne Case, director of the , which is overseeing the IGSA. “By working alongside the Army Reserve, we are helping to safeguard our environment in Hawaiʻi and the Pacific, while supporting mission readiness.”

The new agreement reflects a growing model of military-academic partnerships, where institutions of higher education provide specialized expertise to strengthen DOD operations while creating new applied learning and workforce opportunities for students and researchers.

“Our partnership with the University of Hawaiʻi strengthens our shared mission to preserve Hawaiʻi鈥檚 environment and serve the community,” said Brig. Gen. Katherine A. Trombley, commanding general of the 9th Mission Support Command.

The 9th Mission Support Command is America鈥檚 Army Reserve of the Pacific. Under the operational control of U.S. Army Pacific Command, it provides trained and ready forces to overseas contingency operations. The command has 3,500 soldiers and 160 civilians located in three different countries, three states, three American territories and seven time zones throughout the Pacific.

A leading voice for Indigenous rights in Aotearoa (New Zealand) will visit the University of Hawaiʻi at 惭腻苍辞补 on Thursday, October 30, to discuss the future of Indigenous governance and solidarity across the Pacific.

Debbie Ngarewa-Packer, co-leader of Te P膩ti M膩ori and a member of New Zealand鈥檚 Parliament, will appear in an onstage conversation with Noelani Goodyear-碍补ʻ艒辫耻补, a professor at 糖心Vlog官方 惭腻苍辞补. The free public event at the art auditorium is hosted by the 糖心Vlog官方 Better Tomorrow Speaker Series and begins at 6:30 p.m. ()

“We are deeply honored to host the Honorable Debbie Ngarewa-Packer, whose leadership embodies the courage and clarity our times demand,” said Goodyear-碍补ʻ艒辫耻补. “Grounded in the tino rangatiratanga (absolute sovereignty) of her people and a visionary in her pursuit of thriving futures for Aotearoa and Oceania, she is not only a parliamentarian but a protector. This dialogue is a rare opportunity to learn from her experience and to strengthen the ties between our nations, connected by our great ocean.”

Standing for justice

Ngarewa-Packer has spent decades defending M膩ori lands and waters. Before entering Parliament, she led her iwi (people), Ng膩ti Ruanui, in successful campaigns to block seabed mining off the South Taranaki coast. Those battles continue to guide her work in national efforts for environmental protection, poverty reduction and equity for M膩ori communities.

The Better Tomorrow Speaker Series, which is organizing the event, is a joint venture of 糖心Vlog官方 惭腻苍辞补, The Learning Coalition and the Hawaiʻi Community Foundation, with support from the 糖心Vlog官方 Foundation.

This event is made possible through the sponsorship of Kai膩ulu by Kamehameha Schools, and with additional support from the College of Arts, Languages & Letters, School of Ocean and Earth Science and Technology, College of Tropical Agriculture and Human Resilience and William S. Richardson School of Law.

The University of Hawaiʻi is expanding its environmental support services to the (USAG-HI) through a new Intergovernmental Support Agreement (IGSA) signed September 16, at the Schofield Barracks Seed Lab. USAG-HI oversees key Army lands on Oʻahu, where 糖心Vlog官方 expertise helps balance training needs with protecting island resources.

“This partnership underscores the University of Hawaiʻi鈥檚 role as a trusted partner in conservation and environmental stewardship,” said Chad Walton, 糖心Vlog官方 interim vice president for research and innovation. “Through this agreement, we can apply 糖心Vlog官方 expertise in environmental science and resource management to support the Army鈥檚 mission, while creating new, real-world career and workforce development opportunities in environmental stewardship for our faculty, staff and students.”

Building on partnerships

Since 1995, 糖心Vlog官方 and USAG-HI have worked together through the (ANRPO), a partnership now overseen by the . Through ANRPO, 糖心Vlog官方 researchers support environmental stewardship, conservation and natural resources management initiatives at military installations and training grounds on Oʻahu, which is vital for ensuring military readiness, while preserving Hawaiʻi鈥檚 natural resources.

For example, USAG-HI has supported dozens of 糖心Vlog官方 researchers and technicians to help protect native habitats by conducting research, control and eradication of invasive plants, rodents, slugs and other pests, while also maintaining and restoring populations of endangered plants and animals through development of monitoring, cultivation and reintroduction techniques.

“The University of Hawaiʻi has the experience and expertise, and also the responsibility to our island home, to help ensure the very best education, talent and research in natural research management and environmental stewardship applied to military lands in Hawaiʻi,” said Suzanne Case, director of the 糖心Vlog官方 Office of Land and Ocean Conservation Futures. “This expanded partnership is both an opportunity and a kuleana [responsibility] that we take seriously.”

This IGSA will allow 糖心Vlog官方 and USAG-HI to grow and expand its collaborative opportunities in improving environmental resilience, while growing conservation workforce capacity and impact. The agreement represents a stronger partnership model between the U.S. Department of Defense and local institutions nationwide, allowing military installations to improve their operations while caring for island resources, supporting regional economies and leveraging academic expertise.

“By tapping into 糖心Vlog官方鈥檚 world-class expertise in environmental science and resource management, we enhance our operational readiness while safeguarding Hawaiʻi鈥檚 unique ecosystems for future generations,” said Col. Rachel Sullivan, U.S. Army Garrison Hawaiʻi commander. “This collaboration not only bolsters the Army鈥檚 ability to train and deploy forces under sustainable practices, but it also creates opportunities for workforce development, inspiring students, and researchers to become stewards of these islands. Together, we鈥檙e demonstrating how we can unite to protect our environment, support our community, and build a stronger Army—right here in Hawaiʻi.”

As a kid, Maya Singh heard from her family stories about the ocean and land in Fiji that inspired her passion for the outdoors and, ultimately, for environmental science.

“I grew up in British Columbia, Canada, but my family is from Fiji,” said Singh, who will be graduating this month from the University of Hawaiʻi at 惭腻苍辞补 with a bachelor鈥檚 degree in (GES). “My grandpa would tell me stories of him and his brothers catching shrimp outside and playing in the ocean and rivers. It really inspired me to want to live closer to the ocean.”

With a passion for the environment and ocean, Singh moved to Hawaiʻi after graduating high school to pursue a degree at the 糖心Vlog官方 惭腻苍辞补 . For her senior research, Singh worked with mentor and Assistant Prof. to support coastal management and preservation on 尝腻苍补ʻ颈. She developed a beach carrying capacity tool to determine the maximum number of visitors a beach can hold without surpassing the limits of acceptable environmental or social change at the beach.

As the culmination of this research effort, Singh wrote a senior thesis and presented her findings at the Spring 2025 GES Symposium, a showcase of the research conducted by graduating GES students.

“This tool was developed as a means to understand the changes at the beach and how we can best preserve the beach for future generations,” said Singh. “The thing I enjoy most about conducting this research is being able to work with the community and make a difference. Talking to the local community in the field and connecting with high school students to share the research we are conducting and why it’s important is very fulfilling.”

Meet more amazing 糖心Vlog官方 spring graduates

Supported by funding from the 糖心Vlog官方 惭腻苍辞补 , Singh also worked with Keiko Wilkins, a doctoral candidate in Bob Richmond鈥檚 research group at , to investigate how plastic pollution threatens marine ecosystems. Specifically, she tested the effects of microplastics on sea urchin fertilization. Singh also assisted with collecting and preparing coral samples for Wilkins鈥檚 dissertation research on microplastic effects on corals in the Pacific Ocean.

The academic and research experiences Singh has had through the GES program have solidified her commitment to pursuing a career in Hawaiʻi in environmental science after graduation. Eventually, she hopes to continue with her education by working toward a graduate degree in oceanography.

Approximately 2,000 pollution-fighting “genki balls” were launched into the Ala Wai Canal on November 9, as part of an innovative mathematics lesson combining environmental cleanup with real-world applications.

The genki balls, created by hundreds of University of Hawaiʻi at 惭腻苍辞补 Math 100 students in mid-October, contain nutrient and microbial-rich soil designed to release beneficial bacteria into the waterway. Each teaspoon of healthy soil can contain up to one billion bacteria, contributing more than a trillion beneficial microorganisms to the canal鈥檚 ecosystem. The balls underwent a three-week maturation period before their release into the canal.

“I think that it鈥檚 important for 糖心Vlog官方 惭腻苍辞补 students to get involved in the community and this unit was about microbiomes, ocean acidification and climate change,” said Maʻalaea Collier, 糖心Vlog官方 惭腻苍辞补 math learning assistant. “This group of students, or generation in general, is becoming more aware of the effects. I saw students very engaged and wanting to participate.”

The project, a collaboration between 糖心Vlog官方 惭腻苍辞补鈥檚 and the , incorporates lessons on scientific notation and environmental data analysis. The activity aligns with the course鈥檚 microbiome unit and is part of a new General Education pathway focused on sustainability and climate change solutions.

“It鈥檚 really valuable for the students to not only learn the math but also see it connected to sustainability and community engagement,” 糖心Vlog官方 惭腻苍辞补鈥檚 Department of Mathematics Associate Professor Sarah Post said. “We have a lot of freshmen so this is a way for them to get involved at 糖心Vlog官方 and in the local communities as well.”

糖心Vlog官方 惭腻苍辞补 Interim Vice Provost for Academic Excellence Laura Lyons also joined the students to toss the genki balls into the water.

“What a wonderful way to help them to learn, to be engaged in the community at the same time and to be working on a practical solution for a real problem,” Lyons said. “I have this other feeling which is incredible gratitude because I live along the Ala Wai and this is my walking path. To know that people are caring for it, to know that we can be good stewards of the Ala Wai, that鈥檚 really important to me.”

The Ala Wai Canal, constructed in 1928, is one of the state鈥檚 most polluted waterways, collecting runoff from the 惭腻苍辞补 and P膩lolo valleys. This initiative contributes to the Genki Ala Wai project鈥檚 larger goal of deploying 300,000 genki balls into the canal by 2026, with nearly 200,000 deployed to date. The Japanese word “genki” means healthy and full of vitality.

Learning mathematical concepts while helping to clean one of Hawaiʻi鈥檚 most polluted waterways was the focus of a creative University of Hawaiʻi at 惭腻苍辞补 lesson.

Approximately 400 students enrolled in Math 100 created about 2,000 “genki balls” from October 16 to 18, at the 糖心Vlog官方 惭腻苍辞补 campus. Genki balls, which get their name from the Japanese word for healthy and full of vitality, are made of nutrient and microbial-rich soil, and are designed to sink to the bottom of a waterway and slowly release beneficial microbes.

The activity was sponsored by 糖心Vlog官方 惭腻苍辞补鈥檚 , in collaboration with the . Students worked during their class times in groups of 30 to 50.

“It’s such a good experience relating math to the real world,” 糖心Vlog官方 惭腻苍辞补 student Janessa Mondragon said.

“It’s just one thing to learn in a classroom with a worksheet in front of you, and it’s another thing to have an instructor like Professor Chyba bring us out here and learn with hands-on experience,” 糖心Vlog官方 惭腻苍辞补 student Jacktino Logoai said.

The project aligns with the course鈥檚 unit on microbiomes, incorporating lessons on scientific notation and environmental data analysis. Students learned that a teaspoon of healthy soil can contain up to one billion bacteria, putting the scale of microbial life into perspective. The students鈥� work will result in more than a trillion bacteria going into the Ala Wai Canal.

The Math 100 course is part of a new General Education pathway focusing on sustainability and climate change solutions.

“Actually being out here in the open, putting their hands in the mud, they’re really opening up with each other making connections and making connections with the course material to sustainability, civic engagement and helping out the environment,” Associate Professor Sarah Post said.

Following a three-week maturation period, the genki balls will be released into the Ala Wai Canal. This waterway, created in 1928, has long been considered one of Hawaiʻi‘s most polluted, collecting runoff from 惭腻苍辞补 and P膩lolo valleys.

The students contributed toward the Genki Ala Wai project鈥檚 goal of deploying 300,000 genki balls into the Ala Wai Canal by 2026. The project is closing in on 200,000 so far.

“I am so impressed with these students that they’re interested in the environment and they are our future,” said Mary Ann Kobayashi, Genki Ala Wai project education coordinator. “So it’s so important for them to know the EM (effective microorganisms) technology and what it can do for Earth because they’re the ones that will pass the knowledge on for us.”

Eight undergraduate students from a variety of disciplines at the University of Hawaiʻi at 惭腻苍辞补 experienced an all-expenses-paid research trip of a lifetime—spending eight weeks in summer 2024 immersed in the Galápagos Islands. They engaged in mentored research via a transformational journey that promoted deep connections to ʻ腻颈苍补 (land/sea), k膩naka (people) communities and m膩lama ʻ腻颈苍补 (stewardship of places and people).

Creighton Litton, professor, (UROP) director, and one of the eight 糖心Vlog官方 惭腻苍辞补 faculty members who designed and implemented the program over the past two years, said, “Mentored research opportunities for undergraduate students is a high impact practice that provides myriad benefits to students, mentors, our campus and our islands as a whole. This is an innovative program—possible via a strong collaboration with the (CDF) in Galápagos, and engagement by multiple faculty from across the 糖心Vlog官方 惭腻苍辞补 campus—that provides our students with transformative learning experiences in research science within a Native Hawaiian Place of Learning context.”

More than 80 students applied, and 12 were invited to enroll in a new spring course on island invasion biology to provide a base of knowledge for their mentored research projects. Eight traveled to the Gal谩pagos and four conducted research in Hawaiʻi.

Students developed research proposals in spring 2024 with mentors from 糖心Vlog官方 惭腻苍辞补 and CDF. The collaborative mentorship approach allowed students to develop their research skills while contributing to real-world scientific questions. During the summer, the traveling students were housed at the CDF research station in the Galápagos, where they conducted their research projects focused on island invasion biology.

During the summer experience, students wrote research papers on every aspect of the scientific process, including literature review, data collection and analysis, conclusions and the socioecological implications of their findings. Each student also crafted a personal, contemporary kaʻao (epic story, tale) to document their experiences, from their hua (initial inspiration) to their haʻalele (preparing for the journey) to the huakaʻi (journey) to the hoʻina (reintegration) back into their on- and off-campus communities.

Important invasive species research

Matthew Kahokuloa鈥檚 project involved assessing plant diversity after the reintroduction of giant tortoises on Santa Fé Island.

“Being my first time leaving Hawaiʻi, it was amazing to experience the biodiversity and ecology of another archipelago鈥檚 ecosystem,” Kahokuloa said. “This trip provided me with invaluable field experience, especially in terms of working in remote environments and applying research methods.”

Emily Josefina Velasquez studied the impacts of Caulerpa racemosa (species of edible green alga) on sand dwelling benthic invertebrates (small aquatic animals that live on the bottom of bodies of water) in the Gal谩pagos.

“You couldn鈥檛 walk for 10 minutes without running into a lounging iguana, sea bird, or sea lion, and we were always close to the ocean.” — Nicole Buyukacar

“The Galápagos was a place where my personal growth as an individual thrived and reaffirmed my passion and drive to work in academia,” Velasquez said. “It’s an unforgettable experience. You鈥檙e immersed in your project, living, breathing, and dreaming about it. I was surrounded by scientists from diverse backgrounds, and living and working in an environment where everyone shares a passion for understanding the world around them.”

Nicole Buyukacar鈥檚 project was about the developmental dynamics and temperature sensitivity of the avian vampire fly.

“The most remarkable thing about the town we worked in, Puerto Ayora, was the abundance of wildlife living right there on our doorstep all the time,” Buyukacar said. “You couldn鈥檛 walk for 10 minutes without running into a lounging iguana, sea bird, or sea lion, and we were always close to the ocean. The experience was an incredible blend of learning to integrate academically and socially into a completely different place while constantly being in awe of the natural beauty and learning to understand the reason why it all needs to be protected.”

The students presented their research and kaʻao products at the CDF research station and at the UROP SURE Symposium. Most students are continuing to work with their mentors to produce peer-reviewed journal publications.

This unique opportunity is the result of a collaboration between 糖心Vlog官方 惭腻苍辞补 and CDF and is funded by the National Science Foundation–International Research Experiences for Students ($300,000 grant), the 糖心Vlog官方 惭腻苍辞补 Provost鈥檚 Office to align the overall program with the campus goal of becoming a Native Hawaiian Place of Learning ($100,000) and the 糖心Vlog官方 惭腻苍辞补 Office of the Vice Provost for Research and Scholarship ($80,000). The funds will make the program available to 糖心Vlog官方 惭腻苍辞补 undergraduate students for at least the next two years.

Pressing concerns surrounding the Red Hill water crisis and overall wai (water) access critical to loʻi kalo (taro patches) and loko iʻa (fishponds) across the state were at the center of a new series of forums held at the University of Hawaiʻi at 惭腻苍辞补.

To foster advancing the protection of ʻ腻颈苍补 (land) and wai through policy and law, the 糖心Vlog官方 惭腻苍辞补 hosted the inaugural on December 15, at the East-West Center. Approximately 200 participants attended the conference that brought together academic researchers from 糖心Vlog官方, esteemed community leaders and advocates to discuss ailing issues and the need to turn to ancestral innovation to help solve them.

“The university can really be a catalyst to uplift what鈥檚 happening in our community to try to link our research and our mentoring of students to actually solve real-world problems for our islands today,” said Kamanamaikalani Beamer, who is the Dana Naone Hall Endowed Chair in Hawaiian Studies, Literature and the Environment at Hawaiʻinuākea and a professor at and the .

Kaipulaumakaniolono Baker, a PhD student at 糖心Vlog官方 惭腻苍辞补 opened the conference with an oli (chant), followed by remarks from Hawaiʻinuākea Dean Jon Osorio and Beamer who rallied attendees to passionately chant ʻOla i ka wai, which means water is life. He also dedicated the conference to Dana Naone Hall, a k膩naka maoli (Native Hawaiian) environmental activist. This was followed by the first panel focusing on the significant role wai has in feeding Hawaiʻi鈥檚 communities.

Wai sovereignty and justice

A major focus of the conference was on the current state of water management and access in Hawaiʻi and how state leaders can utilize research compiled at 糖心Vlog官方 惭腻苍辞补 and ʻike (knowledge) from aloha ʻ腻颈苍补 practitioners steeped in rich wisdom passed down from k奴puna to address problems impacting the islands.

“I think here in Hawaiʻi we can really look towards our ancestral systems that solved [issues] for our islands at different scales in different times but are still very viable and valuable for our future today,” Beamer said.

Wai, ʻAi and Iʻa

The first panel featured aloha ʻ腻颈苍补 leaders from loko iʻa, loʻi kalo and wai advocates who expressed the importance of restoring stream flow in critical areas across the pae ʻ腻颈苍补 (Hawaiian archipelago) which can help to support the production of food and customary rights. Panelist H艒k奴ao Pellegrino from Hui O N膩 Wai ʻEh膩 spoke of more than 100 streams on Maui that are currently diverted and the need to restore them.

Wai and Red Hill

The second session addressed strategies on decontaminating water impacted by the Red Hill fuel spill and revealed traditional maps listing freshwater resources on Oʻahu. The panel featured 糖心Vlog官方 惭腻苍辞补 Professor Kapua Sproat (Ka Huli Ao), Ernie Lau (Board of Water Supply), Wayne Tanaka (Sierra Club of Hawaiʻi) and Camille Kalama (Kaʻohewai).

Lau lamented that there are still 400 million gallons of fuel sitting over the aquifer and advocated conference attendees to push for the Navy to defuel tanks. “If another spill happens, ‘Oh my gosh, our poor wai,’” Lau said.

Special keynote

Renowned philosopher, political activist, public intellectual and author Cornel West will headline a moderated keynote discussion following the summit at Kennedy Theatre 5–7 p.m. West will speak on imperialism and the occupation of Hawaiʻi, while placing the islands within the context of peoples鈥� movements for liberation and justice across the world.

“Dr. Cornel West has been one of the most influential thinkers of our time when it comes to race, social justice, economic justice, and the liberation of oppressed peoples and occupied nations,” Beamer said. “He is a globally recognized philosopher and progessive activist for human rights. He is one of the most impressive speakers and academics one can witness.”

Organizers plan to host the Piʻo Summit annually with themes highlighting aloha ʻ腻颈苍补 and sustainability, and how to advance local policy issues as well as increase collaboration. The summit is hosted by Pōʻai Ke Aloha ʻ膧ina, a project of the Dana Naone Hall chair, which aims to elevate aloha ʻ腻颈苍补 practices within our community.

Event sponsors include the , , Hawaiʻinuākea School of Hawaiian Knowledge, , Hawaiʻi Alliance for Progessive Action, Council for Native Hawaiian Advancement, ʻ膧ina Aloha Economic Futures, Kanaeokana and Sierra Club of Hawaiʻi.

Climate change will increase opportunities to see rainbows, led by researchers at the University of Hawaiʻi at Mānoa. The study鈥檚 authors estimate that by 2100, the average land location on Earth will experience about 5% more days with rainbows than at the beginning of the 21st century. Northern latitudes and very high elevations, where warming is predicted to lead to less snow and more rain, will experience the greatest gains in rainbow occurrence. However, places with reduced rainfall under climate change—such as the Mediterranean—are projected to lose rainbow days.

Rainbows are produced when water droplets refract sunlight. Sunlight and rainfall are therefore essential ingredients for rainbows. Human activities such as burning fossil fuels are warming the atmosphere, which changes patterns and amounts of rainfall and cloud cover.

“Living in Hawaiʻi, I felt grateful that stunning, ephemeral rainbows were a part of my daily life,” said the lead author of the study, Kimberly Carlson, who is now at New York University鈥檚 Department of Environmental Studies. “I wondered how climate change might affect such rainbow viewing opportunities.”

Camilo Mora, at the 糖心Vlog官方 Mānoa housed in the , was intrigued by the question and pitched it as the focus of a project for one of his graduate courses.

“We often study how climate change directly affects people鈥檚 health and livelihoods, for instance via the occurrence of heat stroke during climate change-enhanced heat waves,” he said.

However, few researchers have examined how climate change might affect the aesthetic qualities of our environment, and no one had mapped rainbow occurrences under climate change, until now.

Photos from around the world

A team including students at 糖心Vlog官方 Mānoa looked at photographs uploaded to Flickr, a social media platform where people share photographs. They sorted through tens of thousands of photos taken around the world, labeled with the word “rainbow,” to identify rainbows generated from the refraction of light by rain droplets.

Amanda Wong, then an undergraduate student in in 糖心Vlog官方 惭ā苍辞补鈥檚 (SOEST) and a co-author on the paper, said, “We had to sort through photos of rainbow artwork, rainbow flags, rainbow trout, rainbow eucalyptus, and rainbow foods to find the real rainbows.”

The model suggests that islands are rainbow hotspots.

Then, the scientists trained a rainbow prediction model based on rainbow photo locations and maps of precipitation, cloud cover and sun angle. Finally, they applied their model to predict present day and future rainbow occurrences over global land areas. The model suggests that islands are rainbow hotspots.

Rainbow capital of the world

“Islands are the best places to view rainbows,” according to Steven Businger, professor of in SOEST. “This is because island terrain lifts the air during daily sea breezes, producing localized showers surrounded by clear skies that let the sun in to produce majestic rainbows.”

The Hawaiian Islands, dubbed the are predicted to experience a few more days with rainbows per year. The authors stopped short of discussing how changes in rainbow occurrence might affect human wellbeing. However, rainbows are an important part of human culture throughout history and around the world and are aesthetically pleasing.

“Climate change will generate pervasive changes across all aspects of the human experience on Earth,” said Carlson. “Shifts in intangible parts of our environment—such as sound and light—are part of these changes and deserve more attention from researchers.”

In this case, the overall findings are encouraging—it seems people will have more opportunities to make a rainbow connection under climate change.

Hurricanes. Floods. Rising sea levels. No matter where you look, extreme weather events are impacting nations at an alarming rate. And in Hawaiʻi, an island state surrounded by the vast Pacific Ocean, the impacts of climate change are of increasing concern. Fortunately, Hawaiʻi has a voice at the (COP26) in Glasgow, Scotland, United Kingdom.

Marina Karides, a professor in the in the at the University of Hawaiʻi at Mānoa, served as an official observer from the (AAG). In this capacity, she was actively involved in the discussions and exchanging insights with other conference participants.

“We’re thrilled to have a Department of Geography and Environment faculty member representing the university and the state at this globally significant event. By participating in COP26, Professor Karides is able to take the perspectives of Hawaiʻi residents directly to the delegates making the decisions about the future of the planet. When she returns to 糖心Vlog官方, she will be able to bring the lessons she learns at the convention into the classroom to benefit students,” said Reece Jones, professor of geography and department chair.

AAG is the largest association of geographers in the world, with more than 10,000 members from more than 100 countries. On November 9, Karides participated in the Gender Day event on Advancing Gender Equality in Climate Action. In addition to scientists and activists, the session was attended by politicians including U.S. Rep. Alexandria Ocasio-Cortez and Speaker of the House Nancy Pelosi.

“The climate and ecological crisis are global and gendered phenomena. My goal at COP26 is to involve myself in events and meetings to identify how these matters were being addressed and what kind of economic strategies were being considered to shift from fossil fuels and the logic of accumulation. My students and I in GEO/PACS 333 Islands & Archipelagos will be starting our unit on island and climate change in the upcoming weeks. I can now share with them real world experiences of small island developing states and hopefully inspire some of them to participate in global and international NGOs and the UN,” said Karides.

Karides鈥� research centers on transnational feminisms, island studies, global social movements and economic alternatives. It includes the study of island societies, particularly how gender, race, ethnicity and sexuality are shaped by islands. She is interested in alternative economic models that serve social needs and the natural environment better than dominant economic modes.

The eyes of the world are focused on the climate crisis negotiations for the next two weeks as more than 200 world leaders and 20,000 participants, including six from the University of Hawaiʻi at Mānoa, gather in Glasgow, Scotland, U.K. for the annual United Nations Framework Convention on Climate Change (UNFCCC).

The 糖心Vlog官方 Mānoa faculty and students, from the (SOEST) and , will travel to Glasgow as an official observer delegation to the 26th Conference of the Parties (COP) at the UNFCCC, running from October 31 to November 12.

Approximately 200 nations around the world meet each year at COP to negotiate advancements in international climate law and policy. In 2015, COP yielded the now-famous Paris Agreement. This year, the parties will be negotiating issues such as carbon market mechanisms, climate funding for vulnerable countries, and accelerating domestic decarbonization targets.

This year, the 糖心Vlog官方 law school鈥檚 (ELP) has joined forces with SOEST for the delegation. 糖心Vlog官方 law school members include students Joseph Udell and Naima Te Maile, along with faculty members David Forman and Denise Antolini. From SOEST, Associate Dean Chip Fletcher and recent ELP graduate Colin Lee, who is working with Fletcher as a climate change and resilience policy analyst, will be attending. ELP faculty Richard Wallsgrove is coordinating the delegation from Honolulu.

“We borrowed planet Earth from our children and were poor stewards,” said Fletcher. “For future generations to thrive as we have, it is critical that we transform an economy that for more than two centuries has depended on fossil fuels, land clearing and indiscriminate waste disposal.”

“Climate change is accelerating, but it is still possible to arrest global warming at the U.N. target of 1.5 degrees Celsius with the elimination of greenhouse gas emissions by mid-century,” Fletcher added. “This requires government policies that promote: net-zero buildings, renewable energy production and storage, clean industry and transportation and technology that removes carbon dioxide, refocusing ecosystem services toward sustainability, and investing in the preservation of natural capital. Without bold and transformative action in these sectors, we not only risk out-of-control climate change, but also the very resources that provide life.”

This will be the third time that 糖心Vlog官方 has sent an official delegation to the UNFCCC. The 糖心Vlog官方 law school鈥檚 ELP led the 糖心Vlog官方 delegations in 2018 (Katowice, Poland) and 2019 (Madrid, Spain).

Antolini said, “Having our faculty and students directly engaged with and learning in-person from world leaders, climate negotiators, activists, scientists and community groups all deeply committed to solving the climate crisis is an extraordinary opportunity. The climate challenge has called our 糖心Vlog官方 and larger Hawaiʻi delegation, which include the governor and top state officials, to the global stage. To Glasgow, we will bring the success stories of 贬补飞补颈ʻ颈鈥檚 bold leadership on climate solutions. From Glasgow, we will bring home the best and latest thinking on law, science and policy to share with our students, colleagues and the State Legislature and counties. We have no time to waste as we work together to meet the ambitious but achievable state and global net-zero targets for 2030 and 2045.”

The Hawaiʻi Department of Health issued the following news release on May 18, 2021.

The University of Hawaiʻi will upgrade the Waik墨k墨 Aquarium鈥檚 water system within the next five years to protect nearshore waters as part of an agreement with the Hawaiʻi Department of Health (DOH). The Waik墨k墨 Aquarium was established in 1904 and has been an institution of the University of Hawaiʻi since 1919.

Based on the health department鈥檚 assessment, the Waik墨k墨 Aquarium had numerous discharges from its tanks and exhibits from 2014 to 2018 that exceeded the limits for regulated parameters allowed under its National Pollutant Discharge Elimination System Permit. The health department issued the permit and monitors for compliance.

The agreement, called an Administrative Order on Consent (AOC), allows the Waik墨k墨 Aquarium to continue to conduct research and educate residents and visitors about Hawaiʻi鈥檚 precious ecosystem as it takes steps to be in compliance. The agreement also allows the Waik墨k墨 Aquarium to propose and implement a health department-approved environmentally beneficial project valued at $90,000 or more, in lieu of a monetary penalty.

“We appreciate the cooperation from both the University of Hawaiʻi and Waik墨k墨 Aquarium to resolve these environmental issues and commend the University of Hawaiʻi for its commitment to correct the violations identified by the health department,” said Keith Kawaoka, deputy director of environmental health. “The terms of the AOC ensure the Waik墨k墨 Aquarium remains in compliance with the terms of the permit and help prevent potential water pollution that jeopardizes nearshore waters in the future.”

The health department conducted an investigation of the Waik墨k墨 Aquarium and determined its aged water system, which supplies saltwater for exhibits and research areas, was the cause of the exceedances. Upon being notified of the violations, the University of Hawaiʻi and Waik墨k墨 Aquarium management and technical experts began implementing solutions to stop the violations. The Department of Health鈥檚 Clean Water Branch will monitor the University of Hawaiʻi and Waik墨k墨 Aquarium to ensure compliance with the AOC until all of the terms are met.

“Environmental stewardship is fundamental to the Waik墨k墨 Aquarium’s mission and we recognize that we must lead by example,” said Andrew Rossiter, Waik墨k墨 Aquarium director. “These incidents alerted us to the deteriorated condition of our aged water system. Aquarium and 糖心Vlog官方 staff responded promptly and are working closely with the Department of Health to invest in new systems and improve our saltwater treatment processes to protect the surrounding ocean and marine life.”

The DOH is responsible for protecting the quality of water in streams and coastal areas in Hawaiʻi, keeping the state鈥檚 waters fishable and swimmable for everyone. The DOH Clean Water Branch protects public health and the environment by prohibiting discharges that impair water quality and regulating discharges that can cause pollution and degradation to State waters. Owners and operators of wastewater systems must comply with environmental regulations that protect the public. Failure to do so may result in legal action by the State, Federal partners and/or private citizens.

Research at the on hybrid forest ecosystems is directly behind the creation of a bill currently under consideration at the Hawaiʻi County Council that would allow private landowners to receive reduced property tax rates for native forest restoration on Hawaiʻi Island.

Bill 178 is an amendment to the current Hawaiʻi County Property Tax Code, and would also promote the islandwide engagement of preserving native forests. The bill passed two hearings unanimously with the next scheduled for August 5. If it passes the next hearing and is approved by Mayor Harry Kim, it will become law.

Forest ecosystems expert Rebecca Ostertag, a professor of biology and associate program chair of the at 糖心Vlog官方 Hilo, and her colleague Susan Cordell of the U.S. Department of Agriculture鈥檚 Forest Service, are working directly with environmental lawyer Leslie Cole-Brooks, who wrote the bill.

糖心Vlog官方 Hilo student Sebastian Wells, in the professional internship track of the TCBES graduate program, is working as an intern this summer with the County of Hawaiʻi Real Property Tax Division. Wells is developing communication tools to train county employees on evaluating forest management plans.

“My role as an intern is to develop documents that would support the implementation of the proposed legislation as it will help streamline the process for the county, helping them to effectively and efficiently evaluate forestry management plans while also providing landowners with the tools they need in order to maximize the success of their native forest restoration endeavors,” Wells said.

The Haleakal膩 silversword, already one of the rarest species in the Hawaiian Islands, has been declining in recent decades due to drier and warmer climate conditions. Efforts to restore the population should focus on outplanting new plants in geographic areas with the most favorable climatic conditions. That鈥檚 according to a three-year study by researchers from the University of Hawaiʻi at 惭腻苍辞补鈥檚 and the .

“The goal of our study was to understand the specific reasons why silverswords are dying in the wild,” said lead investigator Paul Krushelnycky, an entomologist in CTAHR鈥檚 Department of Plant and Environmental Protection Sciences. “The study helped us better understand what is likely driving the spatial pattern of mortality in the wild population. This is important for coming up with the most effective strategy to ensure the plant鈥檚 continued survival.”

The Haleakal膩 silversword lives only on the slopes of this volcano. Besides its rarity and dramatic appearance, it also plays a critical ecological role in its alpine desert environment, including acting as the habitat for several species of endemic insects. Beyond that, it鈥檚 a good indicator of what鈥檚 happening throughout the world as plants and animals are impacted by higher temperatures and changing rainfall patterns.

Predicting how plants will respond to increased future drought is difficult, because there are multiple factors influencing both drought resistance of plants and local climatic conditions. Krushelnycky and his co-authors, including Kasey Barton of 糖心Vlog官方 惭腻苍辞补鈥檚 Botany department and Creighton Litton of CTAHR鈥檚 Department of Natural Resources and Environmental Management, conducted a detailed study of why the Haleakal膩 silversword has been dying off at lower elevations on the slope and how best to plant new plants that would survive.

After introducing new plants sourced from silverswords growing in different areas of the mountain and planting them at high, medium and low elevations, they tracked the plants for more than three years. They found that plants were more likely to survive at higher elevations, no matter where their seeds had come from. This matched the pattern of mortality in the wild population. They believe this is because lower-elevation plants grow up to be less drought-resistant than higher-elevation plants, and therefore die at higher rates during especially dry seasons.

Krushelnycky explained, “This means park managers should focus their efforts on identifying areas on the mountain where outplanting survival is likely to be highest, rather than trying to take advantage of more resistant genotypes.”

The study, “,” appeared in Ecological Monographs of the Ecological Society of America.

The world is experiencing a variety of effects of global warming, and some parts of Hawaiʻi are seeing a decrease in relative humidity. Those are the unexpected results of research recently published by a team including a PhD candidate in the in the .

Aurora Kagawa-Viviani said the University of Hawaiʻi at 惭腻苍辞补 research effort began as a course project to improve air temperature maps for the Hawaiian islands. Drawing on daily temperature records from 309 stations between 1905 and 2017, researchers explored relationships of surface air temperatures to atmospheric, oceanic and land surface variables.

“We knew that global warming was causing temperatures to increase across the islands, but we were surprised to find that nighttime sea-level air temperature has been rising very rapidly, much faster than suggested by trends averaging records from multiple low stations,”said Kagawa-Viviani. “A weaker warming trend in midday temperatures, especially close to the cloud layer, pointed us to atmospheric drying—decreasing relative humidity—in some parts of our island.”

Added co-researcher Thomas Giambelluca, geography and environment professor and director of the , “This holds significance for understanding how water resources, ecosystems and human populations are being, and will continue to be affected by, climate change over the next decades. These mapping and analysis efforts are steps toward better understanding how these changes are happening now and into the future.”

The paper was published in the .

Studying temperature and elevation

To see how spatial patterns of temperature changed over the years, Kagawa-Viviani and Giambelluca derived the statistical relationships between temperature and elevation each year. This allowed them to not only map temperature patterns, but also provided a unique way to estimate sea-level air temperature and examine long-term changes.

“We were surprised that daytime temperatures in the middle elevations were not increasing, or were even decreasing in some areas,” said Kagawa-Viviani. “We initially thought this was an effect of inconsistencies in the data, but it turned out that atmospheric drying below and within the cloud layer, and associated rising of cloud base, explained the lack of warming in the cloud zone.”

Through the process of eliminating alternative explanations and exploring other atmospheric profile datasets, the connection was made between patterns of temperature and humidity change. By summer 2019, the researchers were able to conclude that the pattern of middle elevation cooling was consistent with lower-level drying and upper-level moistening.

Geography and environment graduate students working with Giambelluca will continue to study changes in Hawaiʻi鈥檚 climate, to project future changes and to analyze how the changes affect water resources and natural ecosystems in the islands.
