Green rice will feed a hungry world


B. McPherson

A quiet, green revolution is taking place in the Philippines. A joint effort by plant scientists in China and the Philippines has developed “Green Super Rice” which builds on the heritage of IR8, the rice developed 50 years ago that saved millions from starvation.

Another revolution is needed now. By 2050, two billion more people will be living on Earth, many in areas where food is scarce. The changing climate is creating stressful conditions and lowered yields of many important food crops.

This revolution relies on plant scientists using selective breeding techniques but also the knowledge gained with regard to genetics. Instead of inserting non-rice genes into the plant makeup, the scientists working on green super rice can now pick and choose gene bundles from rice plants that exhibit the traits needed. For instance plant breeders looking for a drought resistant rice but high yielding can select a gene from a drought resistant rice and insert it into the high yielding variety.

Scientists working at the International Rice Research Institute in the Philippines have developed while working closely with the Chinese Academy of Agricultural Sciences rice ready for planting that is salt resistant, drought tolerant, disease resistant, high yielding without needing fertilizer or pesticide. Even better for poor farmers, the miracle rice was developed using public money so no royalties have to be paid to use the seed. The farmers will own the seed they buy and can save or sell it.

Millions of acres of newly developed flood resistant rice have been planted in India. The new rice suffered flooding and instead of dying thrived and increased their yield.

The lowest castes in India are given the worst land, and the worst lands in Odisha are prone to flooding,” says Zeigler. “So here is a very sophisticated biotechnology—flood-tolerant rice—that preferentially benefits the poorest of the poor, the Untouchables. That’s a helluva story, I think.” Nat. Geographic

While genetically modified (GM) plants such as corn and soy have greatly increased yields over the years, many questions arise as to their safety and environmental impacts.  The corporations such as Bayer and Monsanto that develop these Bt or Roundup Ready plants also retain control of the seeds requiring farmers to buy from them and sell back to them, breaking a traditional way of farming.

In many ways the old farming traditions are the best for small farmers. Diversity of crops and free ranging poultry to help control pests can produce the healthiest and best of foods.

Abandoned Oil Pipelines What Lurks Below?

Image
These photos were taken July 2012 in the historic Turner Valley, Alberta B. McPherson Controversy over new oil pipelines is reaching boiling point in many circles. Heated debate is taking place over the proposed Enbridge Northern Gateway and Keystone Pipeline proposals. Safety, disruption to landowners  and more are being weighed against the money to be made transporting and selling petroleum products. It got me thinking about the old pipelines. What happens to a pipeline when it is too old to use or not needed? It’s a bit of an Alice in Wonderland scene. The US laws and regulations are different from ours in Canada. The Pipeline and Gas Journal is a source of information about abandoned pipelines in Texas. Apparently a pipeline in Texas may be abandoned by a company, but it still retains ownership and may choose to reactivate the line at a later date. In the meantime, the right of way or easement is no longer maintained, but the through which the pipe extends is not ...

Prince Rupert Says No to Enbridge Pipeline

Image
B. McPherson Prince Rupert city council joined a growing list of BC coastal communities that are saying “No” to the Enbridge proposal to build a twinned pipeline from Edmonton to the coast. The decision of the Prince Rupert city politicians was unanimous. Already the village of Kitimaat, Terrace and the Skeena Queen Charlottes Regional District have voiced their opposition to the project. There are ongoing hearings by a federal court appointed Joint Review Panel which are gathering input from interested parties about the proposed Enbridge Northern Gateway Pipeline which would bring crude petroleum from the oil sands of Alberta to the coast of British Columbia. The proposal would see a twinned pipeline run over the Rocky Mountains and through wilderness to the treacherous west coast. The proposed terminus at Kitimat would require tankers to wend their way through the maze of islands and reefs to load up at the head of Douglas Channel. While the hearings and the finding...

Scientists Beginning to Sound Warnings About Atmospheric Nitrogen Compounds

Image
B. McPherson                                                 This short film explains very well the greenhouse effect on Earth. While the world is focussing on the production and release of carbon dioxide into the atmosphere, other gasses are quietly adding to the catastrophe. Methane is a potent greenhouse gas and nitrous oxide is 300 times more efficient at keeping the Earth warmed. While much of the Earth’s atmosphere is made up of the element nitrogen, it is the nitrogen in reactive compounds that is starting to worry atmospheric scientists. The Green Revolution was made possible by the industrial production of chemical fertilizers. It, combined with antibiotics has allowed the Earth’s population of humans to swell from 1.6 billion at the beginning of the 20 th century to seven billion this year. Nitrogen is a key nutrient in plant growth. Unfor...
