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.

Description
The composition of this project can be described as half responsive digital media composition and half social experiment. It is built for the seven screen display of the Decision Theater and utilizes a combination of digital media and creative software tools along with sensor technology to create a media environment that responds to real time physical feedback from participants. The experience uses different desired interactions or “levels” to examine the tension between Shalom Schwartz’ three sets of bipolar cultural values represented in his theory on cultural value orientation. Cultural values are significant drivers of human behavior that change throughout time, however rarely does society name and define these dominant forces outright. This project aims to expose people to consider these forces through interactive discovery and game play. The installation’s primary user input is based on movement and physical interaction and includes visual rewards for desired forms of cooperative engagement. Sustainability science and research often cites education and communication initiatives as the next actionable steps towards a sustainable solution. Art and design are two fields that are uniquely suited for completing this next step, because they both regularly examine, critique, create, and comment as a part of shaping culture and encourage reflexive thinking about our norms and values. The design process included interdisciplinary engagement which is detailed alongside project outcomes, theoretical ties to sustainability, symbolic representations, and observations of user experiences. It may be considered a pilot test of the potential for creative and interactive digital art platforms to allow for the exploration of cultural values and connections to sustainability. This ability to reflect and consider the assumptions that may be engrained within cultural value orientation is fundamentally important to the wider recognition of the cultural shifts needed to create a sustainable future.
