It gives high marks to some crop-based fuels and lambasts others. Meanwhile, two papers published in Science, a leading...

  Keats’ lament of "tears amid the alien corn" aptly sums up the debate on genetically-modified (GM) food. The latest to join this swirling controversy is the humble brinjal, with the government’s genetic engineering approval committee clearing its GM avatar, Bt brinjal. Bt (for Bacillus thuringiensis bacteria) makes toxins that are lethal to insects. GM crops use this to incorporate into plants a gene that helps produce a bacterial pesticide...

The agricultural sector is both an emitter of greenhouse gases and a victim of global warming. Technological change, water utilisation and cropping pattern in agriculture have implications both for emission reduction and adaptation. While hydrocarbons and raw material-based industries contribute to global warming, their productivity is not necessarily affected by the phenomenon, as is the case in agriculture. Agricultural production impacts climate change and, in turn, is impacted by it....

Some 800 million people in the world were malnourished even before the food and economic crises hit.  Now a push to confront this longer-term problem is picking up steam. Leaders at recent global gatherings agreed to back a multibillion dollar initiative to boost agriculture and food security in low-income countries. Discussions on the overall design and level of funding are continuing. In September, the G20 asked the World Bank to...
