The consequences of climate change
Climate change could dramatically increase temperature and humidity in India. What would this mean for future Indians? r.i.c.e. research that is in progress seeks to understand the consequences of climate change on infant health, population health, social conflict, and well-being.
Air pollution and health
A related concern that has become increasingly pressing for India is air pollution. Recent data suggest that ambient pollution levels in north Indian cities are some of the highest in the world, but pollution is not just a problem in urban areas. Ambient pollution levels during the winter in rural north India can be just as bad. r.i.c.e. research explores the health consequences of air pollution and appropriate policy responses.
Coal power generation is expanding rapidly in India and other developing countries. In addition to consequences for climate change, present-day health externalities may also substantially increase the social cost of coal. Using panel data on Indian households, r.i.c.e. research finds that increased exposure to coal plants is associated with worse respiratory health.
Adequate policy responses to climate change and pollution
Research conducted by r.i.c.e. and collaborators has found that optimal climate policy importantly depends on the future of the developing world. In particular, although global poverty is falling and the economic lives of the poor are improving worldwide, leading models of climate economics may be too optimistic about two central predictions: future population growth in poor countries, and future convergence in total factor productivity (TFP). Under plausible scenarios for high future population growth (especially in sub-Saharan Africa) and for low future TFP convergence, the optimal near-term carbon taxes could be substantially larger.
r.i.c.e. research has also found that tackling pollution through a coordinated policy response is essential and cannot be replaced by private solutions such as air purifiers and face masks. An experiment conducted by the r.i.c.e. team found that air purifiers, although they reduce the particulate matter in the air, are unable to bring indoor pollution levels down to safe levels. Even upper class houses are not built to keep the outside air sufficiently sealed out. This means that almost nobody in India can buy their way out of the health consequences of air pollution.
What is r.i.c.e. doing now?
Even though climate change has primarily been caused by people outside of India, Indians will likely experience a disproportionate share of the suffering. How should Indian policymakers tackle the tradeoffs – between poor Indians today and the suffering of future Indians, between the high-emitting lifestyles of Indian elites and the costs of air pollution – that will be necessary for any climate strategy? We hope to contribute to a better understanding of these tradeoffs through further research on the consequences of climate change and pollution on the well-being of current and future Indians.
