Climate Changes may affect the International Rice Market
Climate Changes may affect the International Rice Market

In Japan, with recent studies and research on the climatic changes around the world and uncertainty, it has been expected that this would also cause a reduction in rice production worldwide even with the new technology breakthroughs. The study has claimed that rice losses will be lower than 10 percent even in the hardest hit countries, but it may cause problem due to rising demand of rice, which is estimated to be double of the current demand by 2050.

The temperate zones in western Japan and eastern China are expected to be hit the hardest, but the southern part of the Indochina peninsula and northern part of South Asia may also get affected. It has been estimated that areas like Nepal, Cambodia, China and Vietnam would face the biggest decreases in rice production by the year 2080.

In one other study by two Taiwanese and a US researcher who have concentrated on the impact of rising sea levels on world rice production have also claimed that Vietnam would be hardest hit due to climate change, along with other countries like Bangladesh, Japan, Taiwan, Myanmar and  Egypt. The sea levels are expected to rise by 1 to 5 meters and these countries may have to convert from exporters to importers. But there is hope also wherein it has been argued that with yield improvements due to the development of stress tolerant rice varieties in combination with liberal trade policies can offset the negative effect of climate change on international rice prices.
