A Search for the Relationship between International Food Crisis and Bio-ethanol Policy of the United States Ishikawa Prefectural University
Get PDFShort-run reasons of the world food crisis including US bio-ethanol policy are
1) Unprecedented inflow of parts of world speculative capital (1300 billion),maize (1400 billion),crude oil (2300 billion),copper ($3200 billion). This inflow was caused by the US originated world financial crisis started in 2007. Quadrupling wheat open interest contract on the CBT had occured from 2002 to 2008.
2) Policy-led fast increase of US bio-ethanol production accelerated sharp rise of world maize price. Sharp rise in bio-ethanol demand had occurred in the USA. US accounts for about onethird of the global maize production and two-thirds of global export. The share of US maize used for bio-ethanol production was 11% in 2004. It increased to 23% in 2007,to 34% in 2008,and it will be 46% in 2014 as energy acts of the United States plans.
3) Restrictions of cereal exports by many large cereal exporters.
4) Decline in the dollar value. The following two reasons have been mentioned in the literature.
(1) Sharp rise in the cerealsimports by China and India.
(2) Crop failures caused by weather in the major cereal exporters.But these were not found to be the reasons of the 2008 world food crisis.departmental bulletin pape

Foods and Environmental Problems
Get PDFThe issue of waste of the food becomes the big social problem now. According to our research in Kyoto,it became clear that 40% of the kitchen garbage were leftovers. It is a problem to have much food which is just thrown away being unattached in a leftover.
For the reason,the ratio that processed foods are used for a meal in the home increases and as a result,it seems that they are thrown away easily. In our study,it was estimated that the food loss of Japan reached about 10%.
The role of agriculture has not only food production but also environment preservation. There is environmental pollution in the agriculture,too. The issue of environmental pollution by the pesticide associates with the issue of food safety deeply.
From now on,we must pay attention about not only the domestic food but also the food imported fromforeign countries.
Recently,the movement that is going to get bio-ethanol as fuel from food has been active,but it is not good direction seeing from environmental site.departmental bulletin pape
