How can we reach this goal? To answer this question, we also developed a dynamic model to simulate the overall grazing area and carbon capture patterns based on the adoption rate of rotational grazing. As can be seen from the figure below, the current rotational grazing adoption rate is around 22% in US. If we could increase the adoption rate to 32%, then the grass density of the existing grazing field could increase 33%, and the total grazing area would decrease 26% which means we could use less field for grazing. Most importantly, the carbon capture capability of our land will increase 67% as there would be more plants with strong roots and denser leave. This simulation maybe far from scientific, but it gives us a way to quantitatively recognize how big impacts the grazing industry have on our environment.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-038d9cc elementor-widget elementor-widget-image\" data-id=\"038d9cc\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"497\" src=\"https:\/\/weijiabin.xyz\/wp-content\/uploads\/2022\/08\/Screen-Shot-2022-08-13-at-7.41.05-PM-1024x497.png\" class=\"attachment-large size-large\" alt=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>This study is part of the collaborative studio team at Harvard MDE program.
