Creating a Green Growth Framework for Islands

Description

Islands are some of the smallest contributors to global carbon emissions, yet are among the most vulnerable to the impacts of climate change (e.g. rising sea levels, extreme storms, and declining fish populations due to warming seas). At the same time, due to their smaller scale and local limitations on resources, island communities have been driving adaptation efforts for responding to the impacts of climate change based on their lived experiences and indigenous knowledge. Recognizing that local community members are in the best position to advance sustainability solutions in their respective island communities, our project sought to uncover best practices of islands that are collaboratively working with their communities to promote sustainable development and adapt to climate change, while leading the way in measuring progress on the SDGs. To this end, we interviewed island leaders from Hawaii, Guam, and Tasmania, who have already launched strategies for achieving these goals, and combined their experiences into a framework requested by other island leaders to encourage locally-driven, culturally-relevant green growth initiatives in partnership with our project partner, the Local2030 Islands Network (Local2030IN). Through designing the framework, we learned 17 possible actions islands can take when developing their own green growth initiative, key insights for implementing the SDGs on islands, and how to work alongside a project partner to create a final deliverable.

Exploring Opportunities for Woody Biomass Utilization in Coconino County, Arizona

In northern Arizona, the removal of woody biomass from forested land has garnered a high level of interest as threats of catastrophic wildfires have increased in recent years. Although there has been a great deal of vocal support for forest restoration, efforts on the ground are often stalled by complex federal contracting systems, a weak logging and sawmill industry, low-quality timber, and inabilities to guarantee long-term biomass supplies to processers. These barriers are exceedingly apparent in in the Flagstaff area, where the vast majority of forested land falls under the jurisdiction of the federal government and little infrastructure exists for wood product industries. In order to address these obstacles, forest stakeholders in Coconino County are actively searching for enterprises to utilize material that urgently needs to be removed from the surrounding forests. This project aimed to assist stakeholders in this endeavor by identifying and researching a number of practical and innovative woody biomass utilization enterprises that are suited to the existing regional infrastructure. While there are a variety of ways to process biomass, this project focuses on the following four end products because of their ability to use residual materials from harvest and sawmill operations, their low-tech nature, and the end product’s proximity to potential markets: biochar, compost, wood-plastic composites, and mushroom cultivation. Each of these products, and the processes used to create them, were analyzed and evaluated using a sustainable enterprise framework, and the final results were summarized in a portfolio for stakeholders in the region to review. Although this project offered just a glimpse of what is possible, the ultimate aim was to foster collaborative conversations regarding how forest restoration residues can be used in sustainable and innovative ways.

Biochar Briquettes: Alternative to Firewood and Charcoal Fuel

Domestic energy is an important component of our day to day lives and is something we cannot live without. Imagine how life would be without a means to cook our food, to warm our house, life would be unbearable. As we enjoy these comforts rarely do we stop to think what the opportunity cost is. For those using renewable sources, it is not a big issue, but for those who rely on wood fuel, they have to strike a delicate balance between need for fuel and the need to conserve the greatest support systems of their livelihoods, the forests. The main source of energy for households in many developing countries is biomass, mainly from forests and woodlands. The continued use of firewood and charcoal fuel puts a strain on forests, resulting in adverse effects on the environment such as prolonged droughts, loss of biodiversity, dwindling water resources, changing weather patterns among other sustainability challenges. An alternative to firewood to charcoal lies in biochar briquettes. This paper discusses the role of biochar briquettes in mitigating climate change and serves as a step by step guide on how biochar briquettes may be produced.
