| Carbon terrestrial sinks are often seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. To determine whether this is true for agriculture, one meta-regression analysis (52 studies, 536 observations) examines the costs of switching from conventional tillage to no-till, while another (51 studies, 374 observations) compares carbon accumulation under the two practices. Costs per ton of carbon uptake are determined by combining the two results. The viability of agricultural carbon sinks is found to vary by region and crop, with no-till representing a low-cost option in some regions (costs of less than $10/tC), but a high-cost option in others (costs of $100-$400/tC). A particularly important finding is that... |

| As the demand for organic and natural food grows in the U.S., studies show that consumers would and do pay more for these foods than their traditional counterparts. However, the question remains as to whether consumers really understand the differences between organic and natural products versus common products. The USDA provides an official definition of organic, but there is no official definition or certification for natural products. The general lack of knowledge among consumers concerning organic and natural products can be misleading and hence, there is a need for a better understanding of how consumer pre-existing knowledge and new information regarding organic and natural products influences consumer purchasing behavior. In this study, we research... |
