Description
In Senegal, West Africa, soils are a vital resource for livelihoods and food security in smallholder farming communities. Low nitrogen (N) soils pose obvious challenges for crop production but may also, counterintuitively, promote the abundance of agricultural pests like the Senegalese locust, Oedaleus senegalensis. In this study I investigated how the abundance of locusts and grasshoppers are impacted by soil fertility through plant nutrients and how these variables change across land use types. We worked in two rural farming villages in the Kaffrine region of Senegal. Overall, there was little variation in soil properties and an agricultural landscape low in soil organic matter (SOM) and inorganic soil nitrogen. I corroborated that SOM is a significant driver of soil inorganic N, which had a positive relationship to plant N content. Of the management practices we surveyed, fallowing fields was important for soil nutrient restoration and years spent fallow was significantly correlated to inorganic soil N and SOM. O. senegalensis was least abundant in groundnut areas where plant N was highest. Additionally, I found a significant negative correlation between O. senegalensis abundance and plant N, suggesting that plant nutrients are an important driver of their populations. Grasshoppers, excluding O. senegalensis, were more numerous in grazing areas and fallow areas, perhaps due to a higher diversity of ecological niches and host plants. These results connect land use, soil, and vegetation to herbivores and suggest that improving soil fertility could be used as an alternative to pesticides to keep locusts at bay and improve crop yields.

Abstract
A Case for Co-Ops (AC4CO) is a digital media outreach project that is intended to explore methods for increasing the impact of sustainability solutions, by helping to translate research implications into practical approaches for sustainable business design. The goal for this project is to increase public awareness regarding latent sustainability benefits offered by the proliferation of worker-owned social enterprises. In effort to achieve this goal, AC4CO pulls together a collection of information and resources regarding the design of worker-owned business models that implement social and environmental safeguards. This collated outreach material is hosted on a dedicated website, which decentralizes solutions by making educational material accessible to a diverse audience. Notably, AC4CO features edits from exclusive one-on-one interviews with leading academic scholars from the Julie Ann Wrigley Global Institute of Sustainability at ASU, who share their expert understanding of various sustainable business practices. Each expert offers insight into an integral piece within the constellation of considerations that are involved in the design of sustainable social enterprise models – from procurement policies to waste reduction strategies. Parallel to these interviews, AC4CO also showcases the design process for an emerging, sustainable worker cooperative, by highlighting the incubation of a local beverage business called Together We Brew. This incubation process was directed by fellow sustainability solutions graduate student, Nick Shivka, in collaboration with his ASU project partners, on behalf of their incubator program’s pilot cohort of worker-owner recruits. Weaving these aspects, AC4CO’s video components synthesize fundamental research-based knowledge of solution strategies into plainly spoken dialogue and augments the discussion with tangibility that is delivered through a visual narrative. This narrative lends plausibility to the task of designing business solution strategies, by providing viewers a look into the process as peers work together to figure out how to structure a cooperative business model that can present viable economic opportunity, while also promoting social equity and environmental protection. By stripping away scientific research jargon and simultaneously presenting a visual rendering of a theory of change, AC4CO’s approach frames the content of the video components in a way that enables an inclusive vision to be shared with a broad working-class audience. This method is intended to foster popular appeal, by distilling complex and varying issues into concise key points, while following a clear and coherent storytelling strategy for sustainability solutions. Functioning as a call to action, these video components serve a critical role in the overall digital media outreach project by piquing the curiosity of viewers and inspiring them to engage with the website to learn more. In doing so, the video components support the website’s central mission of providing a consolidated anthology of educational and resource tools, as a strategy for encouraging workers to join the movement by creating new sustainable and worker-owned social enterprises around the United States.
