Increasing Socio-economic Resilience of Utuado Farmers through Agritourism

Description
Utuado, Puerto Rico, is a region that has witnessed many natural hazards, most notably Hurricane Maria that struck the island in 2017 and irrevocably altered its landscape to this day (Holladay et al., 2019; Ortiz, 2020; Benach et al., 2019). In combination with layers of pre-existing vulnerability, such as socio-economic…

Utuado, Puerto Rico, is a region that has witnessed many natural hazards, most notably Hurricane Maria that struck the island in 2017 and irrevocably altered its landscape to this day (Holladay et al., 2019; Ortiz, 2020; Benach et al., 2019). In combination with layers of pre-existing vulnerability, such as socio-economic vulnerability and food insecurity, this has made for a disaster situation (Klein, 2018; Benach et al., 2019; Garriga-López, 2019). However, this disaster has also opened up a window for citizens to rise up and self-organize for the revitalization of their shared communities and spaces; in the agricultural sector, this has manifested as a drive towards a stronger regional economy and the building of food sovereignty through agritourism (Holladay et al., 2019).

In contribution to a larger Southern SARE project, my Master of Sustainability Solutions (MSUS) Culminating Experience (CE) project aims to support this local movement through a collaboration with key local farmers to identify local farm assets through the reconstruction of solution strategies (Forrest & Wiek, 2014) and the designing of an educational program for the adaptation and scaling of identified sustainability solutions to other regional farms (Fraser & Galinsky, 2010). The intended outcomes for this project include (1) the building of community resilience and livelihood opportunity; (2) the increasing of awareness and knowledge of agritourism best practices; (3) the dissemination of knowledge on practices to increase farm- and visitor-readiness; (4) and the strengthening and interconnection of the regional economy. Based on the array of exemplary farms and enterprises that I have conducted research on and engaged with through this project, I have witnessed the potential that the widespread dissemination of agritourism best practices offers for the progressive building up of the regional economy in Utuado, Puerto Rico.

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.
