Back to current edition
Production of rice, one of the world's most important staple crops, is declining while demand steadily increases, particularly in China. As we have reported in earlier editions of New Agriculturist, there are many reasons for this: lack of labour for double cropping, competition for increasingly scarce water, and unseasonal weather due to climate change. This month in New Agriculturist our Focus on section is devoted to how research is attempting to increase rice yield and nutritional value by improving pest resistance, reducing the crop's dependency on water and modifying the nutrition content of rice grain. Latest research indicates that the effect of climate change on rice yield has been under-estimated. According to the US National Academy of Sciences, higher night-time temperatures reduce yield by 15% for every 1°C rise in mean daily temperature. This threatens to negate the advances of the Green Revolution. In Developments we report how the President of the World Bank views climate change and aspects of modern lifestyle that contribute to conspicuous consumption of carbon-based energy. Meanwhile, the effects are already evident in Australia-News-where high temperatures and severe drought have become more frequent, threatening the vast Murray-Darling irrigated food-bowl of the country. And we note, not for the first time, how politics often has a greater impact on agriculture than weather: Country Profile-Guyana, In Print-"The shackled continent", and Developments-Commitment to decentralisation of forestry, all reflect the far-reaching effects of government policies on agriculture, forestry and trade.
