Renewable Energy

Introduction: Energy versus emissions: The big challenge of the new millennium
By Rakesh Kalshian
To maintain its economic growth rate of 8-10%, India needs all the energy it can get. But the momentum of economic growth overrides crucial environmental concerns.

Hotting up: The science and politics of climate change
By Aditi Sen
The world is hotting up. Climate systems are changing. The 1990s were the hottest decade ever, sea levels rose by 10-20 cm during the 20th century, and atmospheric carbon dioxide levels are 31% higher than in 1750.

The Centre for Science and Environment, a non-profit institution known for its rigorous and scientific policy research and advocacy on environmental issues is looking for a Team Head to steer its Renewable Energy Programme.

This report by Him Dhara, an environmental research and action collective, deals with the Asian Development Bank financed hydropower projects in Himachal Pradesh, which are leading to obstruction of the rivers and their consequent disappearance for harnessing energy and making ‘judicious’ use of the water. Within the hydro sector the attention has turned to the Indian Himalayan region which is estimated to have seventy nine per cent of the total hydropower potential of the country.

The technology of ‘run of the river’ (ROR) used to tap “the flow of rivers” in high gradient zones to generate power has given impetus to setting up of hydro-projects in the Himalayan states. In India, the mountainous region of the Himalayas offered the “perfect setting” for such projects, with the availability of several flowing water sources that could be tapped before they reached the plains. Of the Himalayan states, after Arunachal Pradesh, Himachal Pradesh is second in line with a hydropower potential of about 21000 MW. The installed capacity has increased twenty fold (from 326 MW to 6370 MW) in the last ten years indicating the frenzied pace of hydropower development in the state.

This set of presentations from the conference on Outstanding Organic Agriculture Techniques held during September 2009 at Bangalore deals with pest and disease management practices in organic farming, which rely primarily on preventive and integrated methods.

Crop production and plan protection in organic farming

This paper by S R Sundararaman presents organic farming as the only recourse for farmers, to save both livelihood and the health of the soil. Organic farming methods enable farmers save money and turn their farmyard waste into value-added products for increasing crop production. Farmers will not have to be dependent on agri-business companies for seeds, fertilizers and pesticides. Our self-reliance is thus preserved. A large portion of our country's foreign exchange is used to pay for the import of petroleum products. By going organic we will also help our country save on valuable foreign exchange. Our land will keep giving us returns for extended periods of time unlike farming as per the green revolution, where the land stays productive for a short time and then becomes sterile.

The uppermost question in the minds of farmers who have recently converted to organic farming or who want to turn organic is how to ensure that crop production does not reduce and how to protect the plants from disease, without the chemical fertilizers and pesticides that their fields have grown used to. This paper provides the answers and it also seeks to reassure all farmers that there is no farm which cannot turn around and produce quality crops in sufficient quantity, using organic farming methods.
