From UPSC perspective, the following things are important :
Prelims level : Climate Vulnerability Map of India
Mains level : Need and significance of such maps
- For preparing communities and people to meet the challenge arising out of climate, information specific to a state or even district is needed.
- In order to meet this need, a pan India climate vulnerability assessment map is being developed.
Climate Vulnerability map of India
- The map is being developed under a joint project of the Department of Science and Technology (DST) under the Union Ministry of Science and Technology and Swiss Agency for Development and Cooperation (SDC).
- This research programme of DST is being implemented as part of the National Mission for Sustaining the Himalayan Ecosystem (NMSHE) and National Mission on Strategic Knowledge for Climate Change (NMSKCC).
- Such climate vulnerability atlas has already been developed for 12 states in the Indian Himalayan Region, using a common framework.
- Now this methodology will be extended to non-Himalayan states so that we can have a national level climate vulnerability profile for India.
- The atlas is expected to be ready by the middle of 2020.
Why such move?
- Climate risk is interplay of hazard, exposure and vulnerability. There is a rise in climate-sensitive livelihood of people.
- While the occurrence of natural hazards such as landslides, droughts and floods is projected to go up, their impact depends on the level of exposure such as presence of people and infrastructure in areas.
- Hence a common methodology for assessing vulnerability was critical for comparison and for planning adaptation strategies.
- Vulnerability is the propensity to be adversely affected and can be measured in terms of both biophysical as well as socio-economic factors.
- Addressing vulnerability can help reduce risk to climate change. It also helps in identifying what makes a state or district vulnerable to climate change.
- The map for the Himalayan region, developed in consultation with states, has details up to the district level.
- The national map will also do the same, as vulnerability within a state may differ from one region or district to another.
- A common set of indicators will be used vulnerability profile and ranking of 650 districts all over the country.
- Among the priority areas identified for research are glaciology, climate modeling, urban climate, extreme events and Himalayan ecosystem studies.
- In all, climate change cells have been in 25 states in the country and centres of excellence are also being established in states for capacity building.
- Sensitivity of agricultural production is captured by indicators like percentage area under irrigation; yield variability; and percentage area under horticulture crops.
