The world’s small island territories and nations face unique development challenges and are collectively identified as Small Island Developing States by the United Nations (U.N.). These islands commonly experience high costs of living, limited financial opportunities, import dependence and climate vulnerability. Together, these factors create conditions for undiversified and vulnerable economies, contributing to high levels of poverty among island populations. With frequent climate hazards, these challenges become further exacerbated, disrupting both livelihoods and ecosystems that are essential for long-term island sustainability and income generation. The U.N. has emphasized the importance of advancing the Sustainable Development Goals (SDGs) in developing island states, as these states are at the forefront of making sustainable transitions.
The Local2030 Islands Network
To help address these issues, the Local2030 Islands Network was developed as the first island-to-island network dedicated to locally scaling up the SDGs in developing island states. This network emphasizes implementing goals in ways that reflect the realities of individual island communities. Launched in 2019, the network facilitates cooperation between island governments, organizations and local leaders to scale up sustainable development. As of 2025, 28 island states have joined the network, and many more have engaged in planning efforts and identifying localized solutions. The network serves as a platform where islands can share experiences and best practices, identify local priorities and develop actionable plans.
With the network’s support, island members commit to four key objectives to help execute development agendas. These commitments include advancing political leadership to support climate resilience, strengthening public-private partnerships, transparently measuring SDG progress and implementing concrete initiatives that address local goals. The network also includes “communities of practice” (CoP) that focus on priority island-related issues such as sustainable income generation and climate resilience. These CoP serve as digital platforms that bring together experts, civil society members, stakeholders and community representatives to utilize a combination of technical assistance, Indigenous knowledge and modern technology to address multiple challenges and areas of focus.
Guam Green Growth Initiative
One of the network’s recently implemented projects is taking shape in Guam, a United States (U.S.) territory located in the western Pacific Ocean. Known as the Guam Green Growth Initiative (G3), it is part of the island’s 10-year plan for scaling up local SDGs. This plan includes a framework for addressing local goals related to creating circular economies, expanding opportunities in green jobs and building food system resilience.
Recent assessments of Guam’s poverty rate suggest that one in five residents live below the poverty line, a figure that is double that of the U.S.
As part of G3, decision-makers are combining conservation and economic opportunity to address this issue with long-term solutions, with efforts underway to transition the island to a diversified, circular economy that offers greater financial opportunities for residents. This work includes multiple skills development and job preparation programs, as well as efforts to enhance local cottage industries. One skills development program, known as the Conservation Corps, offers paid training for individuals to learn a wide range of skills within the green jobs sector, supporting the island’s transition to a green economy.
Additional programs support the development of small businesses and cottage industries. The G3 Makerspace and Innovation Hub facilitates cottage industry growth by providing local entrepreneurs and businesses with access to specialized tools, technologies and training for sustainable business practices.
G3 also strengthens partnerships with local organizations, including Guam Unique Merchandise and Art, a local nonprofit that provides small businesses with training and grants to help them grow. This support creates additional small-business employment opportunities and reduces reliance on imported products.
Strengthening Food Security and Local Resilience
G3 promotes social and economic protections by enhancing local food security. Guam imports a large portion of its food, resulting in high prices and increased vulnerability to global supply shocks. G3 addresses this issue by supporting local agriculture, aquaculture and community garden projects. The G3 community gardens offer cost-efficient and sustainable solutions that promote local food security, contribute to food banks and support food access for vulnerable populations facing homelessness and poverty.
A focus on agriculture, aquaculture and aquaponics also contributes to food sovereignty and security in Guam. Through partnerships with local nonprofits such as Guåhan Sustainable Culture, G3 provides workforce development and resources for small-scale farmers.
Additionally, five aquaculture and aquaponics projects have been implemented on the island, providing resources for sustainable, year-round crop and fish production. Through educational initiatives, community members learn to manage these systems, building capacity for the expansion of local aquafarms.
Looking Ahead
The Guam Green Growth Initiative demonstrates how locally driven approaches can advance the SDGs in developing island states. By integrating economic diversification and sustainable food systems, Guam moves toward a more resilient future. As challenges persist for island communities, the Local2030 Islands Network continues to support initiatives such as G3, which offer lessons for other islands to replicate and adapt. Continued collaboration and locally based solutions remain vital to building sustainable futures for island communities.
