Sustainable Use of Water

Projections of water demand and supply based on various scenarios provide a backdrop for examining the relevance of alternative interventions to achieve sustainable use of India's water resources. Policy interventions in the water sector need to address the conservation and better use of water by correcting instruments that have resulted in inefficient use of water and pollution of water bodies. Adoption of such interventions must involve a wider dialogue within civil society and a study of the knowledge available from around the world.

Vehicular Pollution Control in Delhi

Many command and control instruments, such as banning old commercial vehicles and banning leaded petrol have been implemented to curb Delhi's air pollution. This paper is an attempt to investigate whether these efforts have led to a commensurate fall in air pollution in Delhi. Our analysis shows that it has not resulted in concomitant improvement in ambient air quality. One of the reasons is reliance on new vehicles, with little emphasis on in-service vehicles. The containment of vehicular pollution requires an integrated approach, with combined use of transport policies and air pollution control instruments.

Pollution: Prevention vs Control

Industrial pollution in many developing countries including India is managed/controlled using end-of-pipe (EOP) treatment. Using available evidence it is argued here that EOP treatment like common effluent treatment plant (CETP) does not fix the problem, as many hazardous persistent organic pollutants (POPs) and toxic metals remain in the treated water or in the sludge. Instead of pollution control, pollution prevention should be the aim of any policy intervention. Besides, an integrated system where prevention rather than the control is the norm along with the use of cleaner production is more relevant in a fast growing economy like India.
