India is the host for the June 5 event that will highlight the link between overall quality of life and the health of the world's ecosystem.
The U.N. Environment Program said that, with 1.2 billion people, India's agricultural sector is putting a huge strain on its forests. New Delhi, however, has one of the more aggressive tree-planting programs in the world to combat the losses.
The country also has plans to develop at least 20,000 megawatts of power from solar energy and another 3,000 MW through wind farms.
UNEP Executive Director Achim Steiner said cities in India are among the "most active" when it comes to environmental action.
"From its manufacturing of solar and wind turbines to its Rural Employment Guarantee Act, which underwrites paid work for millions of households via investments in areas ranging from water conservation to sustainable land management, foundations are being laid towards a fundamental and far reaching new development path," he said.
