The means-based evaluation looks at farmers' practices of agriculture, and the effect-based evaluation considers the actual effects of the agricultural system. For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much CO 2 is being emitted ...

An example of the breadth and types of agriculture policy concerns can be found in the Australian Bureau of Agricultural and Resource Economics article "Agricultural Economies of Australia and New Zealand" which says that the major challenges and issues faced by their industrial agriculture industry are: marketing challenges and consumer tastes
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sectors contribute between 13% and 21% of global greenhouse gas emissions. [2] Emissions come from direct greenhouse gas emissions (for example from rice production and livestock farming). [3] And from indirect emissions.
The increased atmospheric CO 2 level from human activities (mainly burning of fossil fuels) causes a CO 2 fertilization effect. This effect offsets a small portion of the detrimental effects of climate change on agriculture. However, it comes at the expense of lower levels of essential micronutrients in the crops.
The agricultural policy of the United States is composed primarily of the periodically renewed federal U.S. farm bills.The Farm Bills have a rich history which initially sought to provide income and price support to US farmers and prevent them from adverse global as well as local supply and demand shocks.
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least ...
