Impact of climate change on India’s different physiographic regions

 Climate change means modification of temperature,precipitation, rainfall levels at a larger rate. This have direct impact on ecosystem, India is on the receiving end due to its diverse, sensitive physiography. Indian govt ratified Paris treaty COP 21 that aims to reduce the temperature to 1.5 degrees by 2029-30.

How climate change impacts Indian physiography

On Peninsular

• Less rain- water shortage- reduction of ground water table-extreme drought-- latur train incident
• Reduction in yields,
• Cattle also impacted,
• Pests attacks become more as their survival rate expanded,

Indo gangetic plain

• Temperature hike- faster melting of Himalayas- flash floods in goot hills of Himalayas,
• Precipitation hike - huge sediments in rivers- inundation of villages at banks-- shift of course,

On Himalayas

• Booming temperature leads to forest fires,
• Rainfall extremity cause land slides,mud slides,
• Frequency in cloud burst mushroomed recently,

On coastal plains

• Both temperature and rainfall expected to increase due to elnino,
• Floods- devastation
• Sea water level of one meter rise inundate 0.18% of land of western coast,

Coastal land erosion-

• rice yield decline , winter crops too negatively impacted however coconut yield increase,
• Cyclone frequency increased as plenty of moisture supplied at sea,
• Reduction in fish catch,

deserts

• Both temperature and rainfall expected to increase,
• Floods,
• Extreme summers cause intesive droughts,

Way forward

• Adherence to Cop-21 Indices
• Promotion of disaster prevention activities such as sendai frame work,implementation of gadgil,kasturi rangan committee recommendation in system western ghats regions
• Tree belts through out edge of sea
• Afforestation need to be done on pilot basis to neutralize the impact of climate change --campa act,vanam manam need to be focussed
• Shift to less water intensive crops, use of drip irrigation to reduce the impact of ground wateraster Decline
• ISA require a big push that can curb GHG emissions,

If we protect nature ,it will protect us thus conserving environment is the only way to save earth.
