Industries that over-achieve targets will be awarded energy saving certificates that can be traded like carbon. With the aim to make the industrial sector energy efficient, India’s Bureau of Energy Efficiency (BEE) launched its 'Perform, Achieve and Trade' (PAT) scheme on July 4. The scheme has set energy efficiency targets for industries. Those that fail to achieve targets will have to pay penalty. PAT has been launched under the National Mission for Enhanced Energy Efficiency, one of the eight missions under the umbrella National Action Plan on Climate Change, launched in June 2008.

The proportion of organisms exposed to warm conditions is predicted to increase during global warming. To better understand how bats might respond to climate change, we aimed to obtain the first data on how use of torpor, a crucial survival strategy of small bats, is affected by temperature in the tropics. Over two mild winters, tropical free-ranging bats (Nyctophilus bifax, 10 g, n = 13) used torpor on 95% of study days and were torpid for 33.5±18.8% of 113 days measured.

Improving maternal and newborn health in low-income settings requires both health service and community action. Previous community initiatives have been predominantly rural, but India is urbanizing. While working to improve health service quality, we tested an intervention in which urban slum-dweller women's groups worked to improve local perinatal health.

In an article that forms part of the PLoS Medicine series on Big Food, Corinna Hawkes and colleagues provide a perspective from South Africa on the rise of multinational and domestic food companies, and argue that government should act urgently through education about the health risks of unhealthy diets, regulation of Big Food, and support for healthy foods.

In an article that forms part of the PLoS Medicine series on Big Food, Kelly Brownell offers a perspective on engaging with the food industry, and argues that governments and the public health community should be working for regulation, not collaboration.

In an article that forms part of the PLoS Medicine series on Big Food, Carlos Monteiro and Geoffrey Cannon provide a perspective from Brazil on the rise of multinational food companies and the displacement of traditional food systems, and offer suggestions for the public health response.

Vegetation restoration has been conducted in the Chinese Loess Plateau (CLP) since the 1950s, and large areas of farmland have been converted to forest and grassland, which largely results in SOC change. However, there has been little comparative research on SOC sequestration and distribution between secondary forest and restored grassland. Therefore, we selected typical secondary forest (SF-1 and SF-2) and restored grassland (RG-1 and RG-2) sites and determined the SOC storage.

Despite widespread adoption of genetically modified crops in many countries, heated controversies about their advantages and disadvantages continue. Especially for developing countries, there are concerns that genetically modified crops fail to benefit smallholder farmers and contribute to social and economic hardship. Many economic studies contradict this view, but most of them look at short-term impacts only, so that uncertainty about longer-term effects prevails. We address this shortcoming by analyzing economic impacts and impact dynamics of Bt cotton in India.
