The University of Hawaiʻi at Mānoa (CTAHR) is reopening the (ADSC). Local farmers will once again have access to soil and plant testing here in Hawaiʻi at a reasonable cost, instead of sending samples to the U.S. continent.

The center鈥檚 reopening also allows CTAHR to offer free soil and plant testing through July 21, 2026 to farmers whose land and crops were affected by Kona low flooding in March and April.

Every affected farmer can submit up to three free samples for each of the following services:

• Soil nutrient analysis: To determine if essential minerals were leached.
• Plant tissue nutrient analysis: To assess the current nutrient uptake and health of surviving crops.
• Plant disease diagnostics: To identify plant pathogens/outbreaks that may impact crops following flooding.
• Insect identification: To monitor for shifts in pest populations following the storms.

The ADSC will continue to provide soil and plant testing services at reasonable prices to farmers who were not affected by the floods.

“The reopening is a pivotal moment in CTAHR鈥檚 mission to support stakeholders and food security across the state,” said CTAHR Dean Parwinder Grewal. “Fortunately the timing of the reopening also means we can deliver more support to farmers recovering from the floods. We are providing these tests at no cost for the next three months to help our agricultural partners get back on their feet.”

“ADSC has reopened with an improved customer experience, including online payments, rapid turnaround of results, and interpretation of results and recommendations by CTAHR experts,” Parwinder said.

Brian Miyamoto, executive director of the Hawaii Farm Bureau, noted, “The reopening of the ADSC, along with three months of free testing, comes at a crucial time and helps farmers move forward with recovery and replanting. CTAHR is truly stepping up for our farmers, and we appreciate their leadership and commitment to supporting 贬补飞补颈ʻ颈鈥檚 agricultural community during this critical time.”

CTAHR is working to further expand its services to include seed testing, heavy metal testing, animal health diagnostics and food nutrient content analysis for food product labeling. ADSC is also expanding its seed production capacity and will add clean seedling production, which are young plants that are free from germs or disease.

Newly released, first-of-its-kind agriculture maps of the state of Hawaiʻi are expected to help policymakers, land managers and researchers better monitor crop diversity, evaluate land-use change and design programs that support food security and sustainable agriculture. Experts said the new resource can also assist with post-fire disaster assessments, and in the near future, could potentially help better evaluate wildfire risks before a major disaster occurs, such as the 2023 Maui wildfires.

The University of Hawaiʻi at Mānoa, led by project director Qi Chen in the , in collaboration with the National Agricultural Statistics Service (NASS) in the U.S. Department of Agriculture (USDA), released the high-resolution, crop-specific dataset called Hawaiʻi Cropland Data Layer (HCDL). The maps are publicly available via NASS鈥檚 geospatial portals: and .

Filling in the map ‘desert’

NASS collaborated with 东精影业 Mānoa to develop HCDL by using Google Earth Engine and Google鈥檚 DeepMind AI-powered data. Hawaiʻi was previously a “desert” for annual agricultural maps, said Chen in the . He said the lack of maps hinders efforts to track crops, assess land use and support food security in Hawaiʻi.

“This gap in knowledge became especially evident during the 2023 Maui wildfires, when USDA and state agencies had only limited capacity to assess the agricultural impact,” Chen said. “Without up-to-date, field-scale crop maps, agencies were unable to quickly quantify the extent of cropland loss, identify which crops were most affected or prioritize recovery resources. Instead, assessments had to be pieced together from outdated maps, secondary sources and on-the-ground reports, delaying an accurate picture of the disaster鈥檚 effect on Hawaiʻi鈥檚 agricultural sector.”

Maps are currently available for 2024 and 2023. NASS plans to release HCDL for the 2025 crop year in February 2026. This project was supported by a $268,472 grant from the U.S. Department of Agriculture.

Importance of agriculture maps

Chen said developing such maps for Hawaiʻi is particularly critical because of the state鈥檚 unique agricultural landscape. Unlike large-scale monocultures (the practice of growing a single species of plant over a large area), which are common on the U.S. continent, Hawaiʻi鈥檚 farms are often small, fragmented and characterized by diverse crops cultivated side by side.

“While it makes mapping more difficult, it also means that accurate, high-resolution crop maps can provide transformative insights into resource allocation, irrigation planning, invasive species management and resilience to environmental change,” said Zhe Li, project co-director and geographer in the USDA.

Li added that since annual crop maps for Hawaiʻi are now available, they can be integrated with real-time satellite data on weather, drought and wildfire risk to safeguard agricultural production.

“Consider a situation similar to the 2023 Maui wildfires: If high-resolution crop maps had been in place, emergency managers could have quickly overlaid fire perimeters with known crop locations to estimate economic losses and identify which producers needed the most help and immediate support,” Chen said. “Beyond disaster response, the same maps could also be used proactively—by identifying cropland areas most vulnerable to drought or invasive species, with agencies directing irrigation resources, extension services or pest management programs to the farmers who need them most.”

In addition to Chen and Li, members of the research team include: Noa Lincoln, researcher in the in 东精影业 惭ā苍辞补鈥檚 ; Zhengwei Yang, geographer with USDA; Haonan Chen, associate professor of electrical and computer engineering at Colorado State University; and Changyong Cao, chief of NOAA鈥檚 Satellite Calibration and Data Assimilation Branch in Satellite Meteorology and Climatology Division.

A University of Hawaiʻi at Mānoa project to explore how bacteria and fungi interact that could shed light on health, environmental and even household issues has been awarded a $591,606 federal grant.

The project, “Bacterial dispersal and nutrient transport along fungal highways,” looks at how bacteria move with the help of fungi. It will be led by 东精影业 Mānoa Associate Professors Daisuke Takagi from the in the and Nhu Nguyen from the in the .

While fungi are often thought of as molds or mushrooms, they also create tiny thread-like structures called hyphae that form networks across every exposed surface. These fungal “highways” can help bacteria spread and transport substances, including nutrients or harmful compounds, into new environments. By building mathematical models and testing them in controlled experiments, the 东精影业 team aims to better understand how this partnership works and how it affects larger systems.

“This project lets us combine math and biology to uncover the hidden rules of how bacteria spread, which could impact everything from health to the environment,” Takagi said.

Nguyen added, “This grant allows us to explore how tiny interactions between microbes can shape bigger systems like soils, crops, indoor environments and natural ecosystems that people depend on every day.”

The researchers will study how bacteria travel along fungal networks, how they respond to changes in their environment and how they may carry other molecules with them. The findings could help explain how bacteria spread on human skin, across our food, as well as how they move through soil or buildings.

Collaborative research digs in

In the long run, this knowledge could inform public health strategies, agriculture and environmental management. The award highlights 东精影业 惭ā苍辞补鈥檚 growing role in advancing cross-disciplinary research that bridges biology and mathematics to address complex, real-world challenges.

“One of the best parts of doing research at 东精影业 is the collaboration—working across different fields is incredibly fun and rewarding,” Takagi said. “Learning from one another often leads to discoveries we couldn鈥檛 make alone.”

The three-year grant is jointly supported by the National Institutes of Health and the National Science Foundation through a program that funds projects at the intersection of biology and mathematics.

University of Hawaiʻi at 惭腻苍辞补 alumna India Kawelolani Calso Ching is blending soil science with cultural pride as the newly crowned Miss Oʻahu Filipina. Her journey from studying soil health at the to earning this year鈥檚 Miss Oʻahu Filipina title is a study in personal growth and community.

Ching majored in natural resources and environmental management at CTAHR, with a focus in plant conservation and ecosystem management. However, a soil science class provided new perspectives.

“There’s so much about soils that I never knew before,” Ching said, noting that the class revealed “the chemical, physical, and biological properties of soil” and the “huge diversity of soils that we have here in Hawaiʻi.”

After graduating from 东精影业 惭腻苍辞补, her newfound interest led to her work as a laboratory technician in the soil health lab. She鈥檚 currently working on an artificial intelligence-driven farm irrigation project.

Challenging herself to grow

Just as she stepped out of her comfort zone to study soil health, Ching also challenged herself to grow entering a pageant for the first time. While many people see pageants as just a beauty contest, she discovered it was much more than that.

“It’s totally about developing your public speaking skills, being more immersed in your culture, and becoming the best version of yourself,” she said.

Her pageant platforms centered on food security and dance, a topic sparked by her CTAHR education. Ching鈥檚 pageant speech highlighted the importance of agriculture and food security, aiming to educate youth and honor the legacy of her great-grandfather, who was a “sakada,” or Filipino plantation laborer who laid the foundation for the Filipino community in Hawaiʻi.

Ching will compete for the Miss Hawaiʻi Filipina title on August 9, representing Oʻahu amid contestants from other islands.

Two faculty members from the University of Hawaiʻi at 惭ā苍辞补鈥檚 (CTAHR) were recognized as 2024 Volunteers of the Year by the American Society for Horticultural Science (ASHS).

Their collective efforts brought the beauty and innovation of 贬补飞补颈ʻ颈鈥檚 horticulture to an international audience at the 2024 ASHS Annual Conference.

Teresita Amore

CTAHR Associate Researcher Teresita Amore鈥檚 talent and dedication were displayed in the floral arrangements she curated for the event. Amore, who is also a CTAHR alumni, worked behind the scenes, transforming the stage and social spaces with local flowers and foliage. Organizers say her attention to detail and ability to bring the beauty of nature into every corner elevated the experience for attendees.

Hannah Lutgen

CTAHR Junior Extension Agent Hannah Lutgen provided floral arrangements at the conference by bringing a suitcase filled with flowers from Maui. Lutgen鈥檚 contribution, paired with Amore鈥檚 creativity, helped bring a vibrant touch to the event.

“Russell Galanti, Orville Baldos and Tessie did an excellent job and designed the stage arrangements,” said Lutgen. “It was a team effort and many thanks to Tessie for her outstanding leadership.”

The University of Hawaiʻi at Mānoa College of Tropical Agriculture and Human Resources has officially changed its name to the (CTAHR), in a step that CTAHR Dean Parwinder Grewal said will better reflect the college鈥檚 mission and vision (below).

“This update embodies our college鈥檚 commitment to fostering resilience across individuals, communities, economies and ecosystems, emphasizing its focus on sustainable agriculture, climate change adaptation, and family and community well-being,” said Grewal. “We at CTAHR define human resilience as building individual, community and environmental endurance in the face of challenges such as climate change.”

CTAHR aims to lead research and educational initiatives that help prepare Hawaiʻi and the Pacific region to respond to and recover from climate-driven impacts to agriculture and communities.

“Our programs are centered on enhancing the human condition through a comprehensive approach to building resilience in agricultural and natural systems in the face of climate change,” said Grewal.

The process to change the name, which retains the college鈥檚 well known acronym, CTAHR, began shortly after Grewal started as dean of the college in March 2024. He had a series of meetings with faculty, students, staff, and alumni who all supported the name change proposal. A survey conducted among CTAHR faculty, staff, students, alumni and stakeholders found that more than 67% of respondents endorsed the change, with more than 72% agreeing that 鈥渉uman resilience鈥� better captures the college鈥檚 mission and values.

The mission of several of CTAHR‘s departments already reflect the name change such as the , which conducts research and teaching programs on individual and family resiliency. The focuses on research and academic programs in human nutrition and dietetics, to enhance nutritional health of individuals, children and families. The explores human dimensions research through the relationships between humans and the natural environment for improved human management decisions and policy creation. CTAHR‘s extension programs focus on improving economic, social, and health and wellbeing of individuals, families and communities and offer youth development programs such as 4-H to build teenage resiliency.

The school will be changing its signage and webpages over the coming months to reflect the name change. 鈥淗uman Resources鈥� was added to the then “College of Tropical Agriculture” in 1978 when the college merged with the 东精影业 Hawaiʻi Institute of Tropical Agriculture and Human Resources, which was dissolved in 1999. The meaning of “human resources” has since shifted from resources for people, like healthy food and clean water, to primarily being associated with business and personnel management.

CTAHR was the very first college at the University of Hawaiʻi at Mānoa when it was founded in 1907 under the Morrill Act as a land-grant college of agriculture and mechanic arts. The flagship campus now has 17 colleges and schools.

CTAHR Mission

CTAHR creates and delivers knowledge that supports and strengthens families, agricultural and food systems, and the natural environment. We educate and serve the people of Hawaiʻi and those from around the world with integrity and excellence.

CTAHR Vision

CTAHR provides exceptional education, research, and extension programs in tropical agriculture and food systems, family and consumer science, and natural resource management for Hawaiʻi and the international community. We cultivate innovative scientific inquiry, solve real world challenges, and provide experiential learning in an interdisciplinary setting with global impacts.

What鈥檚 the appetite for hot peppers among local growers? To gauge how well specialty peppers would grow in Hawaiʻi and how productive they might be, University of Hawaiʻi at Mānoa (CTAHR) Oʻahu extension hosted a field day at the Waimānalo Research Station over the summer.

Chili peppers are commonly used, both fresh and dried, in many different culinary dishes, however, the production of other chili types has not been nearly as common in Hawaiʻi.

CTAHR extension agent Jensen Uyeda, and specialists Ted Radovich, Tina Mueller and Jari Sugano provided growers and home gardeners with applied science-based information on producing specialty peppers such as jalape帽os, green peppers, paprika and other dry chiles.

“Our objective of the chili peppers field day was to spark interest in producing these foods and to help further diversify the agricultural market,” said Uyeda, of the . “We also wanted to provide another ‘value-added’ option for local growers, since dried chilis and hot sauces are such common products—and access to local peppers would help to increase the marketability of these products.”

Participants also took a walk through the field and greenhouse to get hands-on experience harvesting peppers—and to collect pepper samples to take home.

To address pressing issues for the Pacific Islands such as soil degradation, wildfires, climate change and loss of biodiversity, the University of Hawaiʻi at Mānoa hosted two conferences focused on the study of clay with experts from around the world. The 61st annual meeting of the Clay Minerals Society and 5th Asian Clay Conference were held in June.

The Clay Minerals Society conference鈥檚 theme “Expanding Clay Science over the Pacific and Beyond” helped (CTAHR) scientists鈥� expand their horizons in soil and agricultural sciences.

The conference provided essential knowledge for addressing environmental challenges effectively. Onsite coordination for the conference (and concurrent 5th Asian Clay Conference)—from inception to the final huakaʻi—was provided by the (NREM) and (TPSS).

In honor of the late Goro Uehara, CTAHR鈥檚 internationally acclaimed soil sciences professor, the conference included a special session on variable charge clays that highly influence the behavior of tropical soils.

“I personally feel that this experience has elevated our research group,” PhD student Kristy Lam said. “Mahalo piha to Clay Minerals Society [CMS] chair Yuji Arai and CMS Editor-in-Chief Joseph Stucki for providing us an opportunity to honor both Goro and our elemental ancestors that give birth to our life-giving soils.”

Local planning was led by Susan Crow, Jonathan Deenik, David Pompeani and Tai Maaz as the co-directors of CTAHR鈥檚 new soil health, environment and ecosystem resilience (S(HEE)R) Lab. NREM researcher Linden Schneider brought student volunteers from across the 东精影业 System to support the technical capacity, and Lam organized the opening kīpaepae in collaboration with Hālau ʻŌhiʻa, the huakaʻi to explore the geology, soils and history of southeast Oʻahu in collaboration with Deenik and Scott Rowland of the .

“I would like to thank 东精影业 for arranging and coordinating the student volunteers,” said Arai, of the University of Illinois at Urbana-Champaign and General Chairman of the Conference. “Thank you for your hard work. Your time and support meant a lot to us.”

A researcher at the University of Hawaiʻi at Mānoa (CTAHR) received a Fellow of the American Society of Plant Biology (ASPB) Award which is granted to no more than 0.2% of the current membership each year. Robert Paull, of the , will be formally recognized in June during the ASPB鈥檚 Annual Plant Biology Conference. In 2014, he was previously made a Fellow of both the American Society for Horticulture Sciences and the International Society for Horticulture Science.

Paull鈥檚 research has led to improved crop growth and yield under environmental stress, and extended postharvest life of tropical ornamentals, fruits and vegetables. His research is valued by the agricultural industry, and his publications have led to more than 17,300 citations in his career, with about 1,000 citations per year since 2019. Paull has been placed on Stanford University鈥檚 list of the top 2% of the most-cited scientists in various fields (2022–23).

“Unique to Robert is his willingness to energetically help anyone on any project who requests his assistance,” said David Christopher of the . “He has formed a cadre of respected and grateful national and international academic colleagues, farmers, industry scientists and friends who value his collaborations.”

Paull has made numerous contributions to the areas of tropical and subtropical fruit, nut, vegetables, ornamental physiology and genetics, their postharvest physiology, handling and storage. He has co-authored five books; edited an encyclopedia, seven volumes and proceedings; authored 127 book chapters; and published 151 peer-reviewed journal articles and 138 conference abstracts and presentations.

“We congratulate Robert for his lifetime of diverse, impactful, and exceptional contributions to tropical agriculture, the field of plant biology and for bringing prestige to the University of Hawaiʻi,” said Christopher.

The award is a recognition of a lifetime of distinguished contributions to plant biology and to serve society in areas including research, education, mentoring, collaborations, outreach, and professional and public service.

Bryceson Gregory Kealiʻiwiwoʻoleikamaunakiʻekiʻe Tugade is hoping to convey some important messages as a student speaker at the 鈥檚 commencement ceremony on December 9.

Always seek the “more” in life. Remain curious. Give back to your community. And one of the most valuable messages: Utilize education as a key tool for attaining personal growth and breaking down barriers.

Tugade, 23, of Aliamanu, will receive a bachelor of applied science with a concentration in (SCFS) at .

“As a first-generation college student, this means the world and so much more,” said Tugade, who is Filipino, Native Hawaiian and Chinese. “This upcoming graduation stands as a testament to my family, peers and larger community that education can be a key driver in overcoming and breaking perceived barriers.”

Emerging leader

After graduating from Radford High School in 2018, Tugade enrolled at , where he graduated in spring 2021 with an associate in science in sustainable agriculture—becoming the first in his family to receive a college degree. He then transferred in fall 2021 to 东精影业 West Oʻahu in pursuit of a bachelor鈥檚 degree.

“I was initially scared of the prospect of advancing my education,” Tugade said. “However, with staff and faculty assistance, I was not only becoming increasingly confident in my ability to perform within an academic realm, but pursuit of opportunities elsewhere was not met with doubt.”

Tugade has thrived—academically, professionally and personally—during his time at 东精影业 West Oʻahu. He found mentors in Albie Miles, his academic advisor and an associate professor in the SCFS program, as well as Indrajit Gunasekara, co-founder of the (cultural agroforestry) movement and 东精影业 West Oʻahu financial aid officer, whom Tugade calls, “my aya (older brother in Sri Lankan).”

Gunasekara said Tugade鈥檚 passionate commitment to the Aloha ʻ膧ina (love of the land) movement is very inspiring to many.

“He鈥檚 always driven to expand his understanding of the work we do with the perspective of Indigenous understanding of where his roots belong, as well as making meaning within the framework of scientific theoretical engagement,” Gunasekara said. “He is a remarkable person, a highly intelligent and deep thinker who鈥檚 always ready to step in and to support whenever, whatever capacity the help is needed.”

Miles said Tugade has proven to be an exceptional multidisciplinary food system scholar.

“He has a keen interest in the biophysical sciences, working on the genetics of Polynesian introduced crops with mentors at 东精影业 惭腻苍辞补, while excelling in his understanding of the root causes of many of the challenges we face in the food system of Hawaiʻi and beyond,” Miles said.

‘For my dad’

Tugade aspires to earn a master of science degree at 东精影业 惭腻苍辞补, and eventually a PhD in tropical plant and soil sciences.

“I plan to continue addressing the layers of work that must be done to identify the current environmental, agricultural and social obstacles we face in Hawaiʻi, and strive to find solutions to assist and serve my community,” Tugade said. “By blending my understanding of science and Indigenous Hawaiian knowledge, I can help my community to reclaim control of our local and traditional food systems for health and livelihood.”

Although Tugade didn鈥檛 always see himself pursuing a degree as he was growing up, the prospect of higher learning was always a conversation in his household, and his father emphasized the value of education. His family would participate in fundraising events for students in his father鈥檚 barrio (town) of Bacar, Magsingal, in the Ilocos Sur region of the Philippines.

“During this semester, my resilience was tested once more—my father unexpectedly passed away this October from an advanced stage of TB,” Tugade said. “From grieving with my ʻohana, to focusing on graduation, and navigating a world without him, I hope to embody resilience and the significant role education can play in our lives.”

He added, “This upcoming graduation is for my dad.”

In the wake of the devastating Lahaina wildfire in August 2023, researchers from different fields at the University of Hawaiʻi are embarking on two public impact research projects focused on transforming how we monitor and respond to disasters in the agricultural sector, and analyzing the possible effects of chromium on Lahaina agricultural lands. The projects earned a combined more than $519,000 in grants from the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture.

Safeguarding Hawaiʻi鈥檚 agriculture

Dubbed AgriWatch, this project, funded by a $268,472 grant, aims to bring real-time monitoring and accurate assessments to the forefront of disaster management.

“The unprecedented destruction, loss of life and extensive damage to Maui鈥檚 agricultural areas revealed a critical need for real-time monitoring and accurate disaster impact assessments,” said Qi Chen, project director and professor in the at 东精影业 惭腻苍辞补. “The goal of AgriWatch is to understand vulnerabilities, mitigate risks and foster resilient agriculture practices by developing rapid response and impact monitoring and assessment capabilities for disasters related to fire and agriculture in Hawaiʻi.”

The research team will leverage cutting-edge technologies, including AI, satellite remote sensing, cloud computing and web applications. They plan to create high-resolution crop data layers for 2023 and 2024, using proven deep learning methods. These methods, previously successful in California and Texas, will be adapted for the unique needs of Hawaiʻi. The team will also assemble high-resolution fire and vegetation condition maps, and will create an online disaster monitoring and impact assessment platform that enables near real-time disaster monitoring and impact assessment.

Collaborations are planned with farmer-supporting organizations statewide to provide outreach and training in the use of the data and tools. Organizations include Hawaiʻi Farmers’ Union United, Hawaiʻi Farm Bureau, the Hawaiʻi Food Hub Hui and the 东精影业 Cooperative Extension Services. High school and undergraduate students, including from the Hawaiʻi State 4-H program, will also be invited to participate in research activities.

AgriWatch will fill knowledge and data gaps in crop types, provide open data access and online tools for near real-time disaster monitoring and assessment, restore food production and mitigate disaster risks. Current plans are to have the project developed and ready to use by November 2024.

“AgriWatch will improve understanding of vulnerabilities, develop resilient agricultural practices, and empower farmers and decision makers for rapid responses to future disasters,” said Zhe Li, project co-director and geographer with the USDA. “By integrating state-of-the-art technologies, collaboration and education, the initiative aims not only to address the aftermath of the Maui fire disaster, but to also build a foundation for a more resilient and adaptive agricultural landscape.”

In addition to Chen and Li, members of the research team include: Noa Lincoln, project co-director and associate researcher in the in 东精影业 惭腻苍辞补’蝉 ; Zhengwei Yang, project co-director and geographer with USDA; Haonan Chen, project co-director and assistant professor of electrical and computer engineering at Colorado State University; and Changyong Cao, project collaborator and chief of NOAA鈥檚 Satellite Calibration and Data Assimilation Branch in Satellite Meteorology and Climatology Division.

Investigating possible dangers of chromium

Volcanic Hawaiʻi soils contain large amounts of chromium. Chromium itself isn鈥檛 toxic, however, when heated, chromium can become highly toxic and easily spread. The toxic chromium can affect public health in agricultural communities through multiple exposure routes, including direct skin contact, dust inhalation and drinking water consumption.

This project, funded by a $250,942 grant and led by 东精影业 惭腻苍辞补 and Professor Tao Yan, will investigate the abundance of the toxic chromium in the Maui wildfire-impacted soil, and develop cost effective and practical bioremediation strategies.

Yan and his research team will determine the impact of the wildfires on the toxic chromium levels in agricultural and forest soils through field sampling and laboratory experiments. The team will also conduct laboratory experiments to test mulching and acidic compost amendments as cost-effective and practical bioremediation strategies to reduce the toxic soil.

“The anticipated impact is not limited to the improved understanding of the wildfires鈥� impact on the toxic chromium soil and the development of bioremediation strategies, but also to educate and communicate the associated public health risks to the impacted communities,” Yan said.

The holidays have officially arrived at the University of Hawaiʻi at 惭腻苍辞补 with the annual student Poinsettia Sale, which sells out every year. Nearly 700 poinsettias in a variety of colors will be pre-sold this year during late November and early December. Prices range from $10 to $25 and orders are only taken .

The holiday tradition is hosted by students from the (TPSS) and the 东精影业 惭腻苍辞补 .

“It鈥檚 a great experience for the students involved, especially with the sale鈥檚 awesome turnout every year,” said Jacob Olarti, the Horticulture Society president and TPSS graduate student, who has participated in the sale the last two years. “This is an awesome opportunity, not only to gain hands-on experience, but to spread holiday cheer to our community.”

The planning for the annual holiday tradition begins in the middle of the spring semester and starts with determining which types of poinsettias will be grown in the fall. This year, seven varieties were tested and grown at the 东精影业 惭腻苍辞补 Magoon Research Station.

Students begin planting cuttings in August during the first week of the fall semester. Throughout the semester, they transplant the cuttings into 6-inch pots, fertilize the plants, manage whiteflies with pesticides and maximize branching and growth, ensuring the poinsettias are ready for sale by late November.

“Growing the poinsettias is always fun, even for experienced growers like many of our members,” said Olarti. “I love seeing the different colors as the plants bloom throughout the semester.”

The funds raised support the Horticulture Society and TPSS student activities as well as the next poinsettia sale. Students from the Horticulture Society and students taking TPSS 364 – Horticulture Theory and Practice are responsible for the sale each year.

They鈥檙e assisted by students enrolled in TPSS 402 – Flower and Foliage Crop Production and student volunteers from other disciplines. The project is under the supervision and guidance of TPSS Associate Researchers Orville Baldos and Teresita Amore, as well as Magoon Research Station Manager John Hintze.

A field day introducing the landscape industry to new sterile selections of trees garnered an attendance of nearly 40 landscapers, farmers and residents in July. The event was hosted by University of Hawaiʻi at 惭腻苍辞补 (CTAHR) 鈥� Ken Leonhardt and Alberto Ricordi.

Held at the Waim膩nalo Research Station, the Sterile Landscape Tree Field Day showcased seedless selections of trees (African tulip, monkey pod, shower and octopus) and gall wasp-resistant selections of the tall wiliwili, a tree used as windbreak hedges that commonly takes damage from the pest. Because these trees are sterile, they have no potential to become invasive species. Furthermore, they do not produce seed pod or fruit litter, making them lower maintenance than seedy species.

“Landscapers can use these trees with no risk of introducing more non-native seeds into the environment,” said Leonhardt.

Due to the event鈥檚 popularity, it was repeated on August 21 for the staff of the Honolulu City and County Department of Parks and Recreation, Division of Urban Forestry, which plans to use the trees introduced by CTAHR in city parks as street trees.

“The inquiring public was treated to a very hands-on sharing of research and experiences by Ken and Alberto—the essence of what CTAHR stations and extension gardens are designed to do,” said Jari Sugano, CTAHR Oʻahu County Extension.

Propagation material of the windbreak wiliwili is still available. Interested growers may obtain the free propagation material by contacting Ricordi at albertoh@hawaii.edu.

High school students from across Oʻahu received hands-on training in agriculture directly from the industry’s workforce, thanks to a new program designed by the . In line with CTAHR鈥檚 goal to advance workforce and economic development, its Urban Garden Center partnered with Waipahu High School and its , a pilot program funded by the Department of Labor and Industrial Relations.

When Oʻahu County extension agents learned that Oʻahu high school students were interested in receiving training in landscape and garden maintenance, CTAHR responded by designing a program that addressed specific and individualized workforce development needs. In addition, the program exposed the students to broader career and college opportunities. This partnership supports the goals of the Hawaiʻi State Department of Education and 东精影业 惭ā苍辞补鈥檚 strategic mission.

Student interns learned how to put in weed mat barriers; plant various crops such as ʻulu; harvest seasonal fruit using a fruit picker; install irrigation and secure a weather station. They also harvested and washed lettuce for the chefs at Kapiʻolani Community College and packed local produce for the Hawaiʻi Foodbank. This month they took a field trip to Magoon Research Facility, where the student interns learned about flowering crops such as anthurium, and did orchid work with associate researcher Teresita Amore. Amore spoke about the importance of volunteering and adding service to the students’ resumes.

The interns have also experienced job interviews, worker orientations and safety trainings prior to doing actual work with CTAHR agricultural technicians and extension agents, including Christine Hanakawa and Alberto Ricordi.

Students from Waipahu High School, Pearl City High Shool, Aiea High School, Kapolei High School, Mililani High School, Hawaiʻi Baptist Academy and a student visiting from Washington state participated in the program.“The students from Waipahu High School and Pearl City High School graduated and returned this summer to help with the program, and high school students from Aiea, Mililani and Kapolei are returnees,” said Jari Sugano, Oʻahu County administrator for CTAHR. “It started as a small group of friends who are telling other friends to stay busy this summer versus staying home.”

“Our students were presented with certificates to validate their immersive work and contributions to lifelong serving,” said Ken Kajihara of the Waipahu High School Academy of Natural Resources. “After they graduate, we are hopeful that funding can be secured to make this pilot program a permanent one.”

“We want to engage more students and young adults to enter agriculture. Students have the opportunity to work with the land and see if agriculture is something for them. We try to keep it fun and educational, but it is very hard work,” Sugano said. “They have to be passionate about plants, food security and the environment to make agriculture a career. Not all will end up in agriculture, but we hope they gain life long lessons to take them wherever they go. They did an outstanding job for us this summer.”

The long-term goal is to support graduates in securing long-term jobs in the field of agriculture to ultimately support the advancement of Hawaiʻi鈥檚 landscape, crop production, and nursery and/or greenhouse industries.

The University of Hawaiʻi plans to establish a first-of-its-kind (CliRFIN) that will serve as a hub for Hawaiʻi and U.S-affiliated Pacific Islands (USAPI) to develop collaborative, food innovation solutions driven by Indigenous knowledge systems and modern technology that address climate change impacts.

The $1 million, 24-month award is part of the first-ever U.S. (NSF Engines) Development Awards, which aim to help partners collaborate to create economic, societal and technological opportunities for their regions. The NSF Engines Development Award 2305455: Advancing climate resilient food innovations (HI, USAPI), one of 44 awards granted nationwide this year, provides support for the development of an organizational structure and strategy, including identifying partnerships, resources and initiatives to expand workforce development and commercialization opportunities around innovative, climate-resilient food systems. The initiative could eventually be eligible for another NSF award of up to $160 million.

“This is an exciting and unique opportunity for 东精影业, the State of Hawaiʻi and USAPI to be able to build a collaborative, tech-driven, regional network to support sustainable, long-term-growth solutions to universal issues like climate change and food insecurity,” said Vassilis L. Syrmos, 东精影业 vice president for research and innovation. “This initiative has the potential to position our state as a global leader and serves as an example for other regions to identify with and develop scalable, climate-resilient food systems reflective of their people, place and Indigenous practices.”

There are four phases for CliRFIN:

• Assessment: Conduct in-person meetings with current and potential partners to share information, evaluate resources, opportunities and challenges of expanding food production systems and workforce development in the region.
• Planning: Combine the information from the assessment phase to generate plans to identify and prioritize goals and objectives and the steps to achieve them.
• Coordination: Establish a framework of the organization, communication and knowledge sharing among the network, including governance activities, formal and informal meetings, and social events to facilitate the sustainable growth of CliRFIN.
• Application: Apply for an NSF Engines Type-2 award, worth up to $160 million over a 10-year period, upon solidifying organization and partnerships in order to initiate and ramp up activities over an extended period.

Integrating Indigenous knowledge

“Fundamental to our efforts will be the deep integration of Indigenous knowledge systems and western methodologies to develop a transformative and holistic approach necessary to thrive and sustain these innovative food systems,” said Erik Franklin, CliRFIN鈥檚 director and fisheries team leader. “By underpinning inclusive principles and equitable practices, and broadening our participation of historically underserved and underrepresented populations, we can create more diverse and effective opportunities for identifying problems and solutions.”

The network brings together the skills and expertise of a diverse group of innovators and entrepreneurs from different industries, governments, small businesses and venture capitalists including: East-West Center; Elemental Excelerator; HATCH; Hawaiʻi Good Food Alliance; Hawaii Technology Development Corporation; Natural Energy Lab of Hawaiʻi Authority; Office of the Governor, State of Hawaiʻi; Pacific Disaster Center Global; Hawaiʻi ʻUlu Cooperative; and the University of Guam.

The 东精影业 will provide leadership support for the efforts of CliRFIN with multidisciplinary support provided from 东精影业 惭腻苍辞补鈥檚 leadership teams from: , College of Tropical Agriculture and Human Resources , and .

Growing regional economies

“Solutions to some of our biggest challenges can be found when we incorporate Indigenous knowledge into modern technology,” said U.S. Sen. Brian Schatz. “This new program will do just that, and help us develop better, more resilient ways to continue providing local people with fresh food, even as climate change threatens how we produce and distribute food.”

CliRFIN will engage a collective of 18 Minority Serving Institutions for Native Hawaiians, Asian Americans and Pacific Islanders from: the U.S. Territories of Guam and American Samoa; the Commonwealth of the Northern Mariana Islands; Republic of Palau; the Marshall Islands; and the Federated States of Micronesia.

“These NSF Engines Development Awards lay the foundation for emerging hubs of innovation and potential future NSF Engines,” said NSF Director Sethuraman Panchanathan. “These awardees are part of the fabric of NSF鈥檚 vision to create opportunities everywhere and enable innovation anywhere. They will build robust regional partnerships rooted in scientific and technological innovation in every part of our nation. Through these planning awards, NSF is seeding the future for in-place innovation in communities and to grow their regional economies through research and partnerships. This will unleash ideas, talent, pathways and resources to create vibrant innovation ecosystems all across our nation.”

Weaving, kapa making, poi pounding and wood carving were some of the fun demonstrations attendees could participate in at the 2023 Grow Hawaiian Festival on February 25. Hosted by the friends of , hundreds of people gathered at the garden in Captain Cook on Hawaiʻi Island to celebrate Hawaiian culture and natural history with a variety of activities and speakers. This event was the first the garden has held in more than three years.

The University of Hawaiʻi at 惭腻苍辞补 (CTAHR) contributed to the festival with three educational booths.

• The shared information about the two-lined spittlebug, avocado lace bug, little fire ants and methods for ʻ艒丑颈ʻ补 seed collection.
• Noa Lincoln and his students from the presented a display showcasing traditional sugarcane varieties, samples of fresh-squeezed cane juice and on traditional Hawaiian cultivators and uses of sugarcane.
• Extension forester J.B. Friday from the and education specialist Charlotte Godfrey-Romo discussed Rapid ʻ艑丑颈ʻ补 Death, a fungal pathogen presenting a major issue for Hawaiʻi鈥檚 endemic ʻ艒丑颈ʻ补 trees.

“Despite the unusually wet weather for the leeward side of the island, hundreds of festival goers enjoyed the first public event at the garden since the COVID epidemic,” said Friday.

The Grow Hawaiian Festival aims to foster public understanding, enjoyment and conservation of Hawaiʻi鈥檚 natural resources and provide a space for the appreciation of Hawaiian culture and flora.

Home gardeners learned about irrigation systems and how to build their own systems by using easily obtained products at a free workshop offered by the University of Hawaiʻi at 惭腻苍辞补 (CTAHR). The educational event, held at the in Pearl City in February, was part of the CTAHR (CE) Garden series.

Led by Extension agents, participants got their hands wet by working together to organize common irrigation supplies found in local garden shops. After selecting materials, the group designed their own irrigation systems by connecting tubing to a garden hose attachment, punching a hole in the main line using a hole punch, and fastening a sprinkler emitter to the main irrigation line.

“The presenters spoke at a pace at which beginning gardeners could understand,” said one participant. “We learned the names of the parts, how to put the system together, and had a hands-on experience to help us feel more confident.”

“We take great pride in using the hands-on teaching demonstration method to engage with the public so they can play an active role in their learning. It’s what [Cooperative] Extension does best,” added Jari Sugano, Oʻahu County Administrator and organizer of the Extension series. “I love seeing participants light up with enthusiasm and help one another in understanding science-based concepts.”

Extension agents Joshua Silva, Tina Lau, Amjad Ahmad and Alberto Ricordi from CTAHR鈥檚 coordinated with Oʻahu County Extension staff members to host the workshop. With steady interest and positive feedback from the public, an advanced irrigation workshop is being planned for spring 2023.

The bigger picture

Although this event allowed guests to take part in a fun DIY activity, it ultimately reinforced the importance of water conservation and showed guests the proper use of water, a precious resource in our islands.

During the workshop, CE shared the measures they have taken over the past three years to reduce potable water use at the garden, keeping in mind their neighbors in Red Hill and that community鈥檚 need for quality water for drinking, bathing, cooking and basic activities.

One of the first initiatives taken was selecting more sustainable plants for the typically dry and hot Pearl City environment. The Urban Garden Center also stopped watering their lawns and cut back on irrigating plants that could be rainfall fed. Additionally, they capped unnecessary sprinkler heads and moved to drip irrigation instead of manually watering plants.

“This week we started installing valves on each sprinkler in our greenhouses so we can turn off sprinklers when not in use,” said Sugano. “We removed plants which were highly dependent on daily watering. Slowly we are making strides in reducing potable water use so there will be more groundwater in our aquifers for those who need it.”

Sugano added, “Everyone from large farms to small backyard gardeners play an important role in ensuring our water systems are safe and available for generations to come. Water is the essence to survival in our island state.”
