Question 10

Kerala, a coastal state, is experiencing increased frequency of extreme rainfall events and sea-level rise, impacting its coastal communities and agriculture. Local authorities are considering two major policy interventions:

1. Investing in mangrove restoration along the coast and upgrading stormwater drainage systems in urban areas. 
2. Promoting large-scale solar energy projects and improving public transportation infrastructure to reduce fossil fuel dependency.

Which of the following statements accurately categorizes these interventions according to climate change strategies typically outlined in IPCC reports?

Accepted Answer

B. Intervention 1 is an adaptation strategy, while intervention 2 is a mitigation strategy. — Climate change adaptation refers to adjusting to actual or expected future climate. Mangrove restoration and improved drainage reduce vulnerability to sea-level rise and extreme rainfall, making them adaptation measures (Intervention 1). Climate change mitigation involves efforts to reduce or prevent the emission of greenhouse gases. Promoting renewable energy and public transport reduces emissions, thus qualifying as mitigation strategies (Intervention 2).

Answer

A. Both interventions 1 and 2 are examples of climate change mitigation strategies.

Answer

C. Intervention 1 is a mitigation strategy, while intervention 2 is an adaptation strategy.

Answer

D. Both interventions 1 and 2 are primarily focused on geoengineering solutions.
