With a score of just 3.73 out of 100, India ranks as the worst country for the ill effects of toxic air pollution on human health among 132 nations, according to a report presented at the World Economic Forum 2012. India's neighbors also score poorly for toxic air pollution, but still significantly better than India. For example China scores 19.7, followed by Pakistan (18.76), Nepal (18.01) and Bangladesh (13.66).
In the overall rankings based on 22 policy indicators, India finds itself ranked at 125 among the bottom ten environmental laggards such as Yemen, South Africa, Turkmenistan, Uzbekistan and Iraq while Pakistan ranks slightly better at 120. The indicators used for this ranking are in ten major policy categories including air and water pollution, climate change, boidiversity, and forest management.
These rankings are part of a joint Yale-Columbia study to index the nations of the world in terms of their overall environmental performance. The Yale Center for Environmental Law and Policy and Columbia's Center for International Earth Science Information Network have brought out the Environment Performance Index rankings every two years since 2006.
The Yale-Columbia study confirms that environmental problems in South Asia are growing rapidly. The increasing consumption by rapidly growing population is depleting natural resources, and straining the environment and the infrastructure like never before. Soil erosion, deforestation, rapid industrialization, urbanization, and land and water degradation are all contributing to it.
