Global Warming of 1.5°C. <br /> <br />FOOD FOREST AND POND <br />Carbon Sequestration Rate: According to scientists at NC A&T <br />University, food forests sequester carbon at a rate of 18.2 <br />tonnes/acre/year. The area that will be developed currently has grass <br />and shrubs in one area and lightly planted fruit trees in another. Given <br />the NCA&T figures, we estimate that planting ¼ acre in a fully <br />developed food forest that is closely maintained and managed will <br />sequester: 18.2 tonnes/acre/year × 0.25 acres × 50 years = 227.5 <br />metric tonnes CO2 <br />The addition of a small rain catchment pond will accelerate carbon <br />sequestration on the farm. Taylor et al (reference below) found that <br />small ponds sequester 79-247g of organic carbon per square meter <br />annually, a rate 20-30 times higher than woodlands, grasslands and <br />other habitat types. Our pond will be 21 square meters. If we assume <br />an average level of pond carbon sequestration (163g) we would <br />sequester 3.4kg carbon per year in the pond and 171kg over 50 years. <br />The pond has the additional benefit of creating cooler microclimates in <br />the surrounding area during the summer months, which supports the <br />thriving of other plants and animals on our permaculture farm. <br />References: <br />https://attra.ncat.org/publication/climate-beneficial- <br />practices/#:~:text=Forest%20gardens%2Ffood%20forests%20can,(USD <br />A%20NRCS%2C%202022). <br />https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/fee.1988 <br /> <br /> <br /> <br />Docusign Envelope ID: 61C3903E-05FE-49FE-A6AF-E50B7D61917E
