Project description

Mitigating the Nutrient Collapse: Reduced CO2 microclimate generation via Chlorella algae spatial dominance in a resilient permaculture system for nutritionally desirable food crops.

Adequate nutrition is essential for individual health, as well as social, economic and political stability. Yet, incumbent socioeconomic models are failing to make nutritious food accessible for a large proportion of the world population. Therefore, with social collapse a possibility in the coming decades, it is vital that nutritious food production systems are independent from global resource networks and do not further unsustainable resource extraction. Unfortunately, globally elevated atmospheric CO2 (eCO2) concentrations of 415ppm (parts per million), due to ecologically destructive anthropogenic behaviour, is reducing the nutrient content of staple food crops such as rice, wheat and potato. eCO2 increases the photosynthetic production of sugars, but dilutes nutrients throughout a larger crop. This phenomenon, known as the nutrient collapse, threatens food security even further by transforming otherwise nutritious crops into literal junk food.

This project presents a nature based response to the nutrient collapse that is not dependent on global resource networks. It proposes the employment of rapidly CO2 sequestering Chlorella Vulgaris algae in a microclimate facilitating permaculture system. Symbiosis between multiple natural assets in the arrangement maintain a reduced CO2 (rCO2) microclimate by mitigating air flow and moderating temperature in the immediate atmospheric vicinity of staple food crops. This allows them to develop a more desirable nutritional profile.

Chris is from Reading, UK. He previously studied visual communication at Arts University Bournemouth, before graduating in 2016. He is now aiming to work in permaculture design and ecological resilience.
