Disaster Resilient Infrastructure Current Affairs - 2020

UK confirmed as first co-chair to India led Coalition for Disaster Resilient Infrastructure

The United Kingdom is to co-chair India led CDRI (Global Coalition for Disaster Resilient Infrastructure). The CDRI was established by PM Modi at the G20 meet held in 2017

What is CDRI?

Currently, there is no focus being provided to building disaster-resilient infrastructure. Currently, the focus is being provided only to natural disasters. Under this issue as base, the CDRI will aid in reshaping construction. It will aim in building strong climate resilient infrastructures that will reshape construction in core sectors such as energy, transportation, telecommunication and water.

Significance

According to Sendai Framework, 1 USD spent in disaster risk reduction is 7 USD gained. However, the developing countries are facing problems to balance economic investment and disaster resilient infrastructure. CDRI will help countries in solving these problems.

India as world leader

India is doing so well in preventing human deaths due to disasters. India’s measures to control Corona Virus says it all. For a country with second highest population in the world, the spread is 0.3% which is miniscule as compared to developed countries like USA, UK, France.

India is a world leader in adopting preventive measures to avoid human deaths due to disasters. India’s “Zero Casualty Approach” has gained several praises all over the world including United Nations.

GoI launches “Seismic Hazard Microzonation” to minimize earthquake disasters

The Ministry of Earth Science has launched Seismic Hazard Microzonation project in major cities of India. The project aims to reduce hazards of seismic activities by putting in adequate measures

What is Seismic Hazard Microzonation?

It is the process of dividing earth quake prone areas based on certain factors. The factors include geological and geophysical characteristics of sites. They are ground shaking, landslide, liquefaction susceptibility, rock fall hazard and flooding caused due to earth quakes. Based on the division, mitigation measures are prepared. Hence, it is a preventive method to minimise the losses.

The factors in the microzonation method are estimated based on response from soil layers.

Microzonation in India

So far, the mapping has been done in the State of Sikkim and in other eight cities. The cities are Delhi, Bengaluru, Kolkata, Guwahati, Jabalpur, Dehra Dun, Ahmedabad and Gandhidham.

Japan

Japan is the best example where microzonation techniques are well implemented. The Civil engineering practice in Japan is based on microzonation laws. This helps to design infrastructure with seismic resilience.

Need

The technique gives better mitigatory measures as it helps to understand the impact of seismic activities precisely. In certain places, where no reliable prediction model can be implemented, it is essential to adopt preventive measures.
