Guam Green Growth Conservation Corps learns Food Security & Food Sovereignty at GSC Food Resiliency Hub

Uncategorized

The Guam Green Growth Conservation Corps (G3CC) rolled up its sleeves and partnered with Guåhån Sustainable Cultures (GSC) during the week of June 9, for a deep dive into food sustainability and agriculture.

At the GSC Food Resiliency Hub in Yona, the G3CC learned about food security and food sovereignty, two pillars of sustainable food practices, the former of which ensures access to affordable and healthy food options to all people while the latter is a system wherein the people who grow, share, and eat farmed foods also govern its production and distribution.

The G3CC also helped to prepare garden beds for medicinal plants used in CHamoru culture alongside students enrolled in GSC’s summer program.

The fifth cohort of the G3CC rounded out the week at the Hub by tending to the coffee and fruit gardens on the property. They also assisted in harvesting pandanus leaves.

The group learned the proper and safest ways to plant papaya and pineapple, and helped remove Antigonon leptopus, an invasive species of perennial vine more commonly known as the “chain-of-love” vine.

With this week in books, the G3CC members now feel even more prepared for the emerging green economy with the skills shared by GSC and partners in sustainability like them.

According to members, it is through collaborations like this that the seeds of a more sustainable future for all people are grown.

UOG and Guam DoAg host CNMI reps for State Wildlife Action Plan workshop

Uncategorized

The University of Guam Center for Island Sustainability and Sea Grant’s Island Conservation Lab (UOG CIS & Sea Grant ICL) and the Guam Department of Agriculture Division of Aquatic and Wildlife Resources (DAWR) hosted representatives from the CNMI Department of Fish and Wildlife (CNMI DFW) for a two-day workshop on the Guam and CNMI State Wildlife Action Plans (SWAP).

The Guam and CNMI teams have been working independently to revise their SWAPs, but in a historic step toward regional collaboration, these teams gathered for the first time to discuss shared Species of Greatest Conservation Need. Through this unified effort, the teams identified priority species from both SWAPs and produced key conservation and management goals for the species on a landscape scale across the Marianas.

“Coming together with CNMI to discuss natural resources that we share is a tremendous step in aligning the Mariana Islands. Land, water, plants, various animal & fish species, all have significant cultural and environmental significance to our people,” said director of the Guam Department of Agriculture Chelsa Muña, who is hopeful that the partnership will strengthen the support for the islands’ conservation efforts.

UOG CIS & Sea Grant Associate Director for Natural Resources Else Demeulenaere, Ph.D., added to the SWAP discussion during the event, drawing parallels to the biogeography shared between Guam and the CNMI. “As a biogeographer and ethnobotanist, I see the Mariana Islands as a single biogeographic region, a chain of interdependent landscapes, species, and cultural histories,” she remarked. “Conservation cannot happen in isolation. We are recognizing that what affects one island affects us all, and that protecting biodiversity means thinking and acting at the scale of the whole archipelago.”

UOG CIS & Sea Grant project associate Caley Jay Chargualaf, who works with the Island Conservation Lab on the project, sees a lot of common ground between the two islands and the species that call them home.

“Our plants and animals do not recognize geographic or political borders. The land and sea belong to them as much as they do to us,” said Chargualaf. “It is our responsibility to work together, guided by passion and experience, to ensure these species have the opportunity to thrive in our shared environment.”

According to wildlife biologist and conservation planner Dacia Wiitala from the CNMI Division of Fish & Wildlife, the meeting served as an opportunity to start a partnership that will have a lasting impact.

“The purpose of the workshop was to identify opportunities for collaboration between Guam and CNMI natural resource managers that would result in cost-saving opportunities, regional capacity building, data sharing, and overall improvements to conservation practices for our shared Species of Greatest Conservation Need,” said Wiitala.

Wiitala also stressed the big role community feedback plays in conservation.

“Stakeholder engagement is the most important aspect of conservation planning. Talking with people who have different perspectives and experiences brings up new ideas and considerations that might be missed if you don’t seek out diverse input,” added Witala.

More community meetings will be held in the coming months as updates to the SWAP are ongoing. For more information follow @UOGCIS and @uog.islandconservationlab on Instagram or visit uog.edu/cis today.

At Our Ocean Conference, UOG’s Shelton and other island leaders unveil next phase in Green Growth collaboration

Uncategorized

From strengthening individual green growth hubs to collaborating and sharing knowledge for sustainable development, the Local2030 Islands Network is set to take the next step with the launch of the Green Growth Partnership Community of Practice.

Austin Shelton, Ph.D., director of the University of Guam Center for Island Sustainability and Sea Grant, made the announcement in April in Busan, South Korea at the “10th Our Ocean Conference”on stage next to conference founder and 68th Secretary of State John Kerry.

The Local2030 Islands Network is a global platform advancing island-led, culturally informed sustainable development solutions. Governor of Guam Lourdes Leon Guerrero committed Guam as a founding island member of the Local2030 Islands Network and Shelton serves as a member of its steering committee. The Local2030 Islands Network facilitates the Green Growth movement in islands across the globe.

Shelton described the network’s new initiative as “Green Growth for resilient islands.”

Building on the network’s existing communities of practice — and informed by leading examples like the Sustainable Development Goal (SDG) dashboards created by Hawaiʻi, Guam and Ireland, Shelton said “The network will expand peer learning, increase in-country technical capacity, foster collaboration within and across islands, and share best practices for holistic ridge-to-reef management rooted in circularity, localization and regeneration.”

The launch of the Green Growth Partnership Community of Practice will be shared through the network’s Virtual Island Platform. This free, open-access resource aims to create new opportunities for collaboration across fields, help identify and measure SDG outcomes and support scalable solutions to critical island and ocean challenges.

“Through curriculum co-development, training programs and the continued growth of SDG dashboards, we aim to support transparent tracking of commitments — including those made here at the Our Ocean conference — and drive progress toward national and global sustainability and climate resilience goals,” Shelton said.

“Together, through a commitment to green growth and collective action, we can lead the way toward a regenerative and resilient future,” he added.

In 2023, the UOG Center for Island Sustainability and Sea Grant announced a partnership with the University of Hawaii Sea Grant College Program for the expansion of Green Growth initiatives across the Western Pacific, supported by a $1.4 million grant from the U.S. Department of State through the NOAA National Sea Grant College Program. The grant supports the growth of the Local2030 Islands Network and the Green Growth initiative in the Republic of the Marshall Islands, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, and the Republic of Palau.

Soon after, Palau and the Northern Mariana Islands launched their own Green Growth initiatives in 2024. The Marshall Islands followed, with President Hilda Heine, Ed.D., announcing their commitment to launch their initiative during the 16th UOG Conference on Island Sustainability in April.

The Our Ocean Conference marked its 10th anniversary with the theme, “Our Ocean, Our Action.” The event served as a key platform for setting concrete directions for international cooperation on sustainable ocean development. It also provided a forum for global dialogue on implementing agreements to advance the future of the oceans, including the U.N. Treaty on Plastic Pollution.

UOG introduces 5th G3 Conservation Corps

The 5th cohort of the Guam Green Growth Kupu Conservation Corps, along with Governor Lou Leon Guerrero, Lieutenant Governor Josh Tenorio, UOG Center for Island Sustainability and Sea Grant Director Austin Shelton, PhD, and UOG Center for Island Sustainability and Sea Grant Associate Director for Communications and Engagement Kyle Mandapat, hold signs displaying the 17 UN Sustainable Development Goals in CHamoru.

Uncategorized

The University of Guam (UOG) has announced 12 new participants for the Guam Green Growth (G3) Kupu Conservation Corps, marking its expansion into a six-month program that offers enhanced training and benefits.

The new cohort was introduced by the UOG Center for Island Sustainability and Sea Grant on Monday, March 31, at the UOG Global Learning and Engagement Building.

Over the next six months, the new G3 Kupu Conservation Corps members will receive comprehensive training and hands-on experience in various sustainability areas connected to Guam’s green economy. These areas include agriculture and aquaculture, island beautification, invasive species removal, reforestation, circular economy practices, recycling, and renewable energy.

UOG President Anita Borja Enriquez, DBA, called the new cohort, “the future leaders of Guam’s environmental movement.”

“You will gain valuable knowledge, background, and experiences that will ultimately be passed forward and appreciated through this movement for a more sustainable island,” Enriquez added.

Gov. Lou Leon Guerrero, who co-chairs the G3 initiative with Enriquez, also emphasized the importance of having a new cohort participate in the program. “We need people who are very conscious minded of conservation, of sustainability. Because that’s how we can continue our quality of life that we so much deserve.”

Here are the new members of the G3 Kupu Conservation Corps:

      1. Christian Arriola
      2. Curtis-Robert Bukikosa
      3. Joshua Cepeda
      4. Marrae Cruz
      5. Audree Justine Amuan James-Perez
      6. Mi’yah Max
      7. Eyana Pereda
      8. Matthew Pangelinan
      9. Nicolas Quinata
      10. John Reynold
      11. John Rushworth
      12. Gideon Tyquiengco

Reflecting on his decision to join the conservation corps, Bukikosa said, “I want to take care of the island and make sure that the resources we have last for the future.”

Meanwhile, Max saw the program announcement as an opportunity to contribute more to the island. Reynold, originally from the Federated States of Micronesia and a Guam resident for 14 years, emphasized that “giving back to the community is important.”

UOG Center for Island Sustainability and Sea Grant Director Austin Shelton, PhD, said that the enhanced program came to be because of the investments made by the university and its partners into workforce development, in particular, into the G3 Conservation Corps program.

“This is something that has grown in the past few years,” Shelton said.

According to Shelton, the integration of the G3 Conservation Corps with the G3 Kupu Corps for this cycle offers significant advantages. In addition to expanded training, the program now includes an extra month of salary and healthcare benefits for the participants.

Beyond the program’s benefits, Shelton also emphasized its core impact on building a sustainability mindset, which is foundational for the transition to a green economy. “Your role is really important because this is a workforce development program that supports the road toward a green economy,” he said, addressing the new cohort.

Upon completion, participants will receive a stipend and the opportunity to earn up to 80 continuing education units (CEUs) from UOG Global Learning and Engagement. They will also engage with a diverse range of environmental organizations and initiatives across Guam and the broader Micronesia region. The first G3 Conservation Corps program  was launched in 2021.

What is G3?  
The UOG Center for Island Sustainability and Sea Grant facilitates the  Guam Green Growth, or G3 initiative, in cooperation with the Office of the Governor of Guam and the G3 Working Group, whose members represent all sectors of society. With the 17 UN Sustainable Development Goals and G3 Action Framework as a guide, G3 develops tangible solutions to sustainability challenges and contributes to a green economy for the island region. 

Guam NSF EPSCoR is the catalyst for G3. One of its programs is the G3 Conservation Corps, a workforce development initiative that creates opportunities in the green economy.

Marshall Islands joins Green Growth movement, commits to 100% renewable energy at UOG sustainability conference

Uncategorized

The University of Guam facilitated a historic moment for green economic growth and sustainable development when the Republic of the Marshall Islands (RMI) embraced the Green Growth movement and committed to full renewable energy during the 16th UOG Conference on Island Sustainability.

On Friday, April 11, Marshall Islands President Hilda Heine, PhD, who served as the keynote speaker at the conference, signed the Blue Planet Climate Agreement, officially pledging the Marshall Islands’ commitment to transition to 100 percent renewable energy by the year 2045.

This agreement, established in partnership with the Blue Planet Alliance, reinforces the nation’s critical role in climate action and builds upon its 2018 adoption of the 2050 Climate Strategy, which aims for net-zero emissions through renewable energy.

“This alliance today is helping us to move forward to meet that goal. So it’s really supportive of that commitment that we made back in 2017,” said Heine.

The Marshall Islands now joins a network of other island nations, territories, and states—such as Guam, CNMI, Hawaii, Tonga, and Tuvalu—who have committed to the Blue Planet Climate Agreement. This growing global effort is a demonstration of resilience and collaboration among island communities to overcome their shared energy challenges.

Francois Rogers, executive director of Blue Planet Alliance, emphasized the importance of this collective agreement, highlighting its role in fostering cooperation among island nations.

Alongside the signing of the Blue Planet Climate Agreement, Heine also officially joined the Green Growth movement at the conference. Witnesses in the signing included Gov. Lou Leon Guerrero of Guam, UOG President Anita Borja Enriquez, DBA, who are the co-chairs of the Guam Green Growth or G3 initiative.

On the important role of the Green Growth movement in strategically implementing measures addressing global sustainable development goals, Celeste Connors, co-chair of the Secretariat for Local2030 Islands Network said, “This is what we’re signing today. It’s recommitting to these green growth principles, island values, and really measuring what matters to our community, building on our political leadership, and implementation and concrete action.”

The Local2030 Islands Network facilitates the Green Growth movement across the Pacific region.

The 16th UOG Conference on Island Sustainability also hosted the first Green Growth Summit, where Borja Enriquez said the Green Growth movement is for the future of the island, “Who are we doing this for? We are doing this for our manhoben, for our youth, for generations to come.,” she said.

At the start of the conference, Borja Enriquez emphasized the university’s part in the movement, “Our conference theme underscores the urgency and proactive approach that we are taking to secure a sustainable future for our island and the broader Pacific region. And the University of Guam plays a vital role in generating knowledge and developing practical solutions for island sustainability,” she said.

UOG Center for Island Sustainability and Sea Grant Director Austin Shelton, PhD, said the expansion of the Green Growth on Guam and across the region indicates an increasing acceptance of the importance of sustainable development. “Sustainability used to be a fringe idea, now it is the centerpiece of global accords — thanks to the United Nations Sustainable Development Goals. And Guam has found its place as a leader in that movement,” he said.

In 2023, UOG announced its expansion of the G3 Initiative across the Western Pacific, following a $1.4 million grant from the U.S. Department of State through the NOAA National Sea Grant College Program. This grant supports the expansion of the Local2030 Islands Network and the Green Growth Initiative to the RMI, CNMI, Federated States of Micronesia, and the Republic of Palau.

G3 regional partner CNMI Green Growth reports food security initiatives at CIS2025

Uncategorized

Leveraging regional partnerships with the Guam Green Growth (G3) initiative along with local knowledge and innovation, the CNMI Green Growth—one of the latest members of the expanding Green Growth movement across Micronesia—has outlined its accomplishments at the first Green Growth Summit, including initiatives to promote regenerative agriculture and agroforestry to enhance food security.
The 16th UOG Conference on Island Sustainability hosted the Green Growth Summit. G3 assisted the CNMI in launching its own Green Growth initiative after receiving support from the US Department of State through the NOAA National Sea Grant College Program in 2023 to expand the movement.
“Like many of our islands, we import 85 to 95 percent of the food consumed in the Marianas. Just a few decades ago, everyone here knew how to grow, raise, and harvest food locally,” said Patricia Coleman, co-chair of the CNMI Green Growth working group at the G3 Summit.
According to Coleman, the number of farmers transitioning to regenerative agriculture and agroforestry practices is steadily increasing.
Regenerative agriculture and agroforestry focus on strategies that aim to restore and enhance the health and resilience of ecosystems, including soil, water, and plant life.
So far, Coleman said CNMI Green Growth has partnered with various organizations to revive the Luta Agricultural Fair after a six-year hiatus and establish Mama Food Forest Life, encouraging future generations to grow their food regeneratively.
Illustrating how movements can influence policy creation, Coleman noted that the Mariana Islands Legislature Association, with support from the Guam and CNMI legislatures, passed a resolution to reclaim the CNMI’s food system and promote the practices of regenerative agriculture and agroforestry.
Other initiatives by the CNMI Green Growth include a commitment to achieving 40 percent renewable energy in the CNMI by 2030, according to Coleman.
When the CNMI Green Growth Initiative launched in January 2024 in Saipan, key figures in the G3 initiative praised the move, considering it a strategic step toward sustainable development in the Micronesian region. 
CNMI Governor Arnold Palacios and Northern Marianas College (NMC) President Galvin Deleon Guerrero co-chair the CNMI Green Growth initiative. Similar to its G3 counterpart, CNMI Green Growth has established a Working Group to develop a CNMI Green Growth Action Strategy.

First Green Growth Summit at CIS2025 celebrates Guam’s role in expanding movement across Micronesia

Uncategorized

At the first Green Growth Summit, Austin Shelton, PhD, director of the University of Guam Center for Island Sustainability and Sea Grant, talked about how the Guam Green Growth (G3) initiative began.
 
What started as a local sustainability effort has now grown into an expanding regional movement, according to Shelton, who spoke at the Summit on the third day of the 16th UOG Conference on Island Sustainability (CIS2025).
 
Shelton noted that G3 started when Guam was invited to join as a founding member of the Local2030 Islands Network in 2019 after forming a partnership with Hawai’i Green Growth and its CEO, Celeste Connors.
 
At that time, Shelton was still working to establish support for G3 on the island and heard from Connors about the launching of the Local2030 Islands Network at the 74th UN General Assembly.
 
In a determined push he rallied Guam’s leadership, even personally intercepting Lt. Gov. Josh Tenorio, who later became the G3 steering committee co-chair, as he was leaving his house to speak at a government event to present the idea of becoming a founding member.
 
“Guam can be a leader in this. We have an opportunity to be founding members of this network. And he (Tenorio) said, OK,” Shelton said.
 
Two weeks later, Tenorio was on board a plane for New York, where he would represent Guam at the Local2030 Islands Network and commit to the 17 UN Sustainable Development Goals on the sidelines of the UN General Assembly.
 
Soon after, Gov. Lou Leon Guerrero signed Executive Order 2019-23, which established G3 and appointed representatives from government, academia, the private sector, and civil society.
 
UOG was designated as the lead facilitator to ensure that the effort transcends political transitions—this strategy is modeled after the long-standing Micronesia Challenge, which has endured changes in leadership across the region, according to Shelton.
 
With the support of the Governor and UOG President Anita Borja Enriquez, DBA, G3 expanded and became the largest public-private partnership in Guam, inspiring change throughout Micronesia and fostering new green growth movements among neighboring islands.
 
“They really bring this all together and elevate Guam Green Growth and the movement for our sustainable future here on our island, and we’re getting attention worldwide because of their efforts and the efforts of the Guam Green Growth Working Group,” Shelton said.
 
Last year, with support from the US Department of State through the NOAA National Sea Grant College Program, G3 has assisted Palau and the Commonwealth of the Northern Mariana Islands in starting their own initiatives, while also backing new coordinators in the Federated States of Micronesia and the Marshall Islands, as reported by Shelton.
 
At the closing of CIS2025, the Marshall Islands formally joined the Green Growth movement.
 
Today, Shelton said the G3 initiative is anchored by a public dashboard that tracks progress not only in environmental areas such as tree planting and renewable energy, but also in health, education, economic development, and cultural preservation.
 

Initial results of valuation study show G3’s socio-economic potential

Uncategorized

For every dollar invested in the Guam Green Growth (G3) Conservation Corps at the University of Guam, the island receives more than three times that amount in economic and social value, according to the partial results of an economic valuation of the G3 initiative.
 
Christian Valencia, an economist, revealed a snapshot of the ongoing study during the 3rd day of the 16th UOG Conference on Island Sustainability.
 
According to Valencia, the study aims to answer a crucial question: How does the G3 initiative — starting with the G3 Conservation Corps — impact the island economically, and how can this information guide future decisions?
 
With $1.5 million in legislative funding and a $500,000 local match from 2022 to 2024, G3 is estimated to generate an annualized benefit of $1.7 million, according to Valencia. Around $521,461 of the local investment was appropriated for the G3 Conservation Corps program.
 
“This results in a return on investment (ROI) of 3.42, meaning for every dollar invested in the G3 Conservation Corps, Guam receives more than three times that amount in economic and social value,” Valencia said.
 
Valencia provided samples of some of the activities evaluated in the study.
 
An example involves the removal of invasive algae by the G3 Conservation Corps from Guam’s coral reefs, in collaboration with NOAA, the Marine Lab, and the National Park Service. The estimated economic benefit of this effort is $1.7 million per year, based on reef-related economic values associated with diving and snorkeling activities.
 
Tree planting efforts under the Guam Restoration of Watersheds (GROW) have also produced significant results. To date, over 5,400 trees have been planted, contributing to carbon sequestration, improved air quality, and stormwater mitigation. These activities have an estimated long-term benefit of $235,000 over the next 20 years, according to Valencia.
 
“Just putting everything in perspective, these are preliminary estimates, and of course, our work continues, but it’s already clear, G3 is leveraging these local investments to achieve more value for our island community,” he added.
 
Valencia highlighted the importance of moving beyond traditional economic indicators, such as the Gross Domestic Product (GDP), which he said often fails to capture the full value of sustainability efforts.
 
“GDP only measures market output, but it does not account for the non-market benefits of environmental conservation, social equity, and public health,” he said. “Our goal is to put a number to the value of these initiatives and show how they contribute to the broader well-being of the island community.”
 
As the project continues, Valencia will refine their models to quantify the impacts of G3’s work further, helping policymakers and the public understand the actual value of investing in a sustainable future for Guam.
 
The Pacific Research on Island Solutions for Adaptation (Pacific RISA), based at the East-West Center and Arizona State University, supports the economic evaluation study.

UOG Sustainability Conference townhall explores ocean and wave energy for the island

Uncategorized

The University of Guam Center for Island Sustainability and Sea Grant held a townhall at the 16th UOG Conference on Island Sustainability to gather stakeholder input on using ocean energy systems for renewable energy and exploring benefits for local industries, especially aquaculture.
 
Community members representing the academe, private sector, and public sector attended the meeting, which included presentations by experts from the Pacific Northwest National Laboratory (PNNL) on ocean and wave energy systems and their various applications.
 
At the start of the meeting, Bastian Bentlage, PhD, UOG associate professor of bioinformatics, mentioned that the collaboration with PNNL began with a project exploring the feasibility of using ocean energy to power a proposed Guam Aquaculture Innovation Center.
 
Bentlage is the project co-principal investigator. With PNNL and SANDIA National Laboratories, the project team explored technologies like ocean thermal electric conversion (OTEC) and wave-energy converter (WEC) systems.
 
 “One of the biggest costs in aquaculture is energy,” Bentlage explained, underlining the urgency for renewable energy solutions. He noted that alternatives like wind and solar are being explored, but ocean energy offers significant potential through systems such as OTEC and WEC.
 
Andrea Copping, PhD, project manager/principal investigator at PNNL’s Energy and Environmental Directorate, started with a presentation on OTEC, a technology that generates electricity by tapping into the temperature difference between warm surface water and cold deep water.

Copping said a temperature variance of around 20 degrees Celsius is essential, a condition that Guam’s waters easily meet. She reassured attendees that implementing OTEC would not involve drilling through coral reefs, employing other techniques instead.
 
Copping also introduced seawater air-conditioning (SWAC), which uses cold seawater to cool buildings and facilities. “This is the one I think is really pertinent right now, right here for Guam,” she said, noting that air conditioning costs significantly contribute to the island’s current electrical load and that SWAC could offer a sustainable cooling solution.
 
Wave energy was another focal point of Copping’s talk, highlighting Guam’s favorable wave conditions. She noted that while wave energy technology is still in development, it holds potential for small-scale applications, particularly in supporting aquaculture.
 
Throughout her talk, Copping underscored the environmental considerations inherent in these technologies. “We have to be very careful protecting the marine environment,” she said, addressing community concerns about potential impacts on local ecosystems.
 
Other community questions raised in the meeting include the resilience of OTEC systems to typhoons. According to the presenters, designs are being developed to withstand extreme weather conditions. Submerged systems use deep pipes to reduce storm-related risks, while land-based facilities could be structured like traditional buildings to enhance stability.
 
Questions about the size and design of wave energy converters were also discussed, with economic factors playing a crucial role in determining their placement and anchoring strategies. The feasibility of placing OTEC systems close to shore was also discussed. The presenters said that, while possible, positioning systems beyond the surf zone is preferable to prevent damage from wave action.
 
Charles Gunzel, a program manager at PNNL’s Energy and Environmental Directorate also highlighted the importance of understanding economic and regulatory challenges in deploying wave energy technology. He said navigating coastal management policies will be essential for successful implementation.
 
Participants also shared ideas about the innovative uses of OTEC, such as sustainable agriculture solutions like cooled greenhouses in Guam, which could potentially support local food production.
