Water/commodity series (2)Per capita wheat production: China, US, and India

Using wheat production and population data for China, US, and India since 1960, we analyzed per capita wheat production. Because per capita wheat consumption is fairly stable over time (though it can change a little bit by changing lifestyle, diet, economic status, etc), from per capita wheat production, it can be shown whether a country is self-sustained, in need of significantly huge import, or in excess for export.

Water/commodity series (1)Wheat yield: China,US, and India

China shows the biggest improvement in yield over last 50 years; it improved almost by six times, while United States only doubled and India tripled. Although China and India showed very similar yield level in 1960s, China started to take off around early 1970. United States shows a relatively little change in yield and China caught up US in terms of yield around 1982. Since 2000, US and India have been showing almost stagnant yield at a similar level, while China has steadily improved its yield even higher.

Fourth of July fireworks: water contaminants?

Fourth of July fireworks across the United States are definitely a long tradition that millions of people eagerly wait and enjoy. The concern is that fireworks traditionally have included potassium perchlorate as the oxidizer, a material that provides the oxygen that fireworks need to burn and that perchlorate is an environmental pollutant with potential adverse effects on people (it affects the functioning of the thyroid gland) and wildlife. However, the good news is that we are making the right way to “green” fireworks, green as in environmentally friendly. According to American Chemical Society news, Fourth of July fireworks might go green in near future.

No reason to care about water

Don’t get upset–it is merely an instance of irony. Irony works in getting people’s attention and emphasizing the real meaning behind it. The video is more for the general public who are not familiar with water issues, but it can also be motivating to professionals and people who are active concerning water issues. The message… read more

Seawater desalination: the solution?

Water is an increasingly scarce commodity in many parts of the world, and it seems seawater desalination is one of very attractive solutions available to these regions. Of all the Earth’s water, 94 percent is saltwater from the oceans and only 6% is fresh. If plenty and easily accessible seawater could turn into fresh drinking… read more

Do you still drink bottled water?

For most of the readers of this post, the issue of bottled water might not be entirely new. Surely there has been rising awareness and alarming voice about the downsides of bottled water. However, the market is undeniably still growing. Bottled water market is growing on a global scale and, especially in the U.S., the volume is unparalleled-total 8.8 billion gallons, which is 29 gallons per person (in 2007). In the U.S., bottled water has been the second largest commercial beverage category by volume, next to carbonated soft drinks. So I summarized the problems of bottled water again and suggested some recommendations in this post.
