The Role And Cultivation Of The Third Party Power In Food Safety Problems, Jiang Jie
Food and Machinery
In recent years, frequent exposure of the food safety problems have caused people to panic and social unrest. Now “Unified” government regulation pattern in China already can't adapt to the new problems under the wave of reform. The existing supervision method must be adjusted, and develop the third-party to fully mobilize the strength like industry associations, testing organizations, news media and social public to participate in the food safety supervision, and construct the food safety supervision system which is government-led and governed collaboratively by multiple subjects.

Effect Of Ozone Treatment On Quality Of Steamed Breads, Li Bo, Gao Xin
Food and Machinery
The wheat was treated by ozone fumigation method at concentration of 5 mg/L for 0, 0.5, 1.0, 1.5 and 2.0 h, respectively. Then the wheat flour was used to make steamed bread. The ozone treatment effect on steamed bread quality was evaluated by the specific volume, texture profile analysis, and sensory evaluation. The aspect ratio increased with the increased ozone treatment time, however, the specific volume increased first and then decreased. For the texture profile analysis, 1.0 h ozone treatment could reduce the α-amylase activity and increase the gluten content, which increased the hardness and elasticity of the steamed bread. …

The Agricultural Footprints On The Environment, Philip Houtz

Industrialized agricultural systems have given America a convenient and affordable means to supply a surplus of food products to its citizens. Transgenic technology, synthesized fertilizers, advanced pesticides, concentrated animal feeding operations (CAFOs), and the use of farm machinery have all contributed to humanity’s ability to feed the world’s rapidly growing population. However, the energy-intensive food operation of today may not be as ideal as we assume. Fossil fuels are burned to meet the energy requirements for the continual production of large quantities of fertilizer and to keep farm machines operational. Fertilizer and pesticide runoff from farmland ultimately drains into rivers …

Increasing Ecosystem Services Benefits Through Spatially Coordinated Land Management: Role Of Transaction Costs And Communication In An Experimental Setting, Simanti Banerjee, Timothy N. Cason, Frans P. De Vries, Nick Hanley
Cornhusker Economics
The delivery of ecosystem services benefits from proenvironmental land use and land management activities on farmland can often be substantially enhanced if landowners are able to coordinate their decisions across space. For example, in the face of pollinator population collapse, greater crop pollination benefits will accrue if neighboring farmers commit to reducing pesticide usage, than if only a single farmer unilaterally curbs use, leaving bees vulnerable to pesticide drift from neighboring farms. Other examples which illustrate the importance of spatial coordination for generating environmental benefits across space are water quality improvement and biodiversity protection via reduction in habitat fragmentation.

Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman
Journal of Environmental and Resource Economics at Colby
With global population increasing faster than ever, the need to protect land from development is at an all-time high. This paper seeks the measure the public preference for a new national park located in northern Maine. A national park will both protect the land and inject a much-needed economic stimulus to the surrounding communities. The study uses the choice experiment valuation method to quantify its results. Through this revealed preference we can quantify which characteristics are most important to the public so that these characteristics may be considered if the project is ever approved.

Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis
Journal of Environmental and Resource Economics at Colby
The global agriculture sector is responsible for close 20% of the aggregate anthropogenic greenhouse gas (GHG) emissions emitted since the start of the industrial age. Much of these emissions are attributed to the degradation of soils due to land use change when native ecosystems were converted to agricultural fields. Soil organic carbon (SOC) has been found to decrease in temperate soils when the native (such as a forest or grassland) ecosystem is replace by croplands. The aggregate amount of organic carbon stored in soils globally is estimated be 3.3x the size of the atmospheric carbon pool. Further soil degradation and …
