India needs $1 trillion by 2030 to combat climate change: study

02 December 2015

India needs to spend over $1 trillion from now until 2030 to adapt to the adverse impacts of climate change, which has already begun to impact the lives of some 800 million people, or nearly 64 per cent of the country's population, a study has found.

The study by IIM Ahmedabad, IIT Gandhinagar and Council on Energy, Environment and Water (CEEW), a Delhi-based think-tank, said the Indian government spent $91.8 billion on adaptation in 2013-14 alone and this spending is expected to reach $360 billion by 2030.

India as a whole will experience 1-1.5 degrees Celsius increase in mean annual air temperature in the near term from 2016 to 2045, which could have ''profound implications for agriculture and crop production'', the study released on Tuesday said.

These effects could be further pronounced given the estimated increase in extreme precipitation events, resulting in flooding and significant damage to infrastructure.

The study identifies India's preliminary financial, technology and knowledge gaps in adaptation, as well as capacity building and institutional needs. The study was conducted by Professor Amit Garg (IIM Ahmedabad), Professor Vimal Mishra (IIT Gandhinagar) and Dr Hem Dholakia (CEEW).

Adaptation to climate change is a key component at the ongoing Paris climate summit where 196 countries are trying to negotiate a new pact to tackle climate change and keep the rise in global temperature to below 2C of pre-industrial levels by the end of the century.

The study estimated that ''as many as 800 million people living across nearly 450 districts in India are currently experiencing significant increases in annual mean temperature going beyond the 2C warming pathway''.

The study said that given these risks of climate change, the total government spending on developing capacity and adaptation in India has grown consistently over the last decade and a huge $91.8 billion was spent in 2013-14 alone.

''This spending would have to reach $360 billion (in 2005 prices) by 2030,'' it added.

The loss and damage from extreme events were estimated additionally at $5-6 billion per annum.

''The issue of climate change is complex, especially the concept of adaptation. At the national level, the assessment of vulnerability and adaptation needs to be carried out comprehensively. There is an urgent need of enhancing capacity in this area. Moreover, there is also need to comprehensively map the current adaptation measures, gaps and policy actions required in the future,'' said Ashok Lavasa, secretary of the ministry of environment, forest and climate change, in the foreword of the study.

India's Intended Nationally Determined Contribution (INDC), which forms the basis for climate negotiations in Paris, reiterates the need for better climate change adaptation by enhancing investments in development programmes in sectors vulnerable to climate change, particularly agriculture, water resources, Himalayan region, coastal regions, health and disaster management.
