Construction of Delhi Metro's rapidly expanding network, which has breached the 200 km milestone recently, has resulted in the felling of over 40,000 trees till date while nearly 4 lakh saplings have been planted to compensate the loss. The figures assume significance in the light of Delhi High Court's observation that the "magnitude" of trees cut by Delhi Metro Rail Corporation (DMRC) for various projects has led to rise of air pollution in Delhi. During its Phase I and Phase II construction, Metro had obtained permission to cut a total of 38,958 tress.

This book deals with the economic and environmental benefits of plants already growing in Delhi and also the plants, which can be grown in Delhi for economic, medicinal, aesthetic or environmental benefits.

Poultry rearing has always been an integral component of livestock production system in India. Poultry production in India has taken a quantum leap in the last four decades, emerging from an entirely unorganized and unscientific farming practice to a commercial production system with state-of-the-art technological interventions. Indian commercial poultry sector has advanced remarkably due to a scientific approach adopted by the industry and an enabling environment created by the Government. The Indian Poultry Sector is broadly divided into organized and unorganized sub-sectors.

Unless there is either a major slowdown in economic growth, or strong steps to curb CO2 emissions sharply, we can expect continued accumulations of CO2 emissions in the atmosphere – and the resulting global warming with all its consequences says William Nordhaus in this new book published by Yale University Press.

At Copenhagen in December 2009, the international community agreed to limit global warming to below two degrees Celsius to avoid the worst impacts of human-induced climate change. However climate scientists agree that current national emissions targets collectively will still not achieve this goal. Instead, the ‘ambition gap’ between climate science and climate policy is likely to lead to average global warming of around four degrees Celsius by or before 2100. If a ‘Four Degree World’ is the de facto goal of policy, we urgently need to understand what this world might look like.

As we all know, junk food is defined as food with empty calories — it provides fat, sugar and salt, without nutrition. But how bad is it? This is what CSE's laboratory checked recently. The results were both predictable and alarming.
