Floods less likely to be severe when cyclones hit dry land before monsoons, finds study

Climate-Related Disasters Pose ‘Major’ Growth Threat in Middle East, Central Asia – IMF

The frequency and severity of climate-related disasters are rising faster in the Middle East and Central Asia than anywhere in the world, posing a “major threat” to growth and prosperity, IMF Managing Director Kristalina Georgieva said.

A new International Monetary Fund paper showed that climate disasters in the region injured and displaced 7 million people in an average year, causing more than 2,600 deaths and $2 billion in physical damage.

In Morocco, for instance, simulations showed that beefing up water infrastructure improved resilience to droughts and cut GDP losses by almost 60%.

“Droughts in North Africa, Somalia and Iran. Epidemics and locust infestations in the Horn of Africa. Severe floods in the Caucasus and Central Asia. The list of disasters is quickly getting longer,” Georgieva said in remarks prepared for the World Government Summit in Dubai.

Analysis of data spanning the past century showed that temperatures in the region had risen by 1.5° C, twice the global increase of 0.7° C, and already sparse precipitation had become more erratic than in any other region, the IMF report said.

Georgieva said extreme weather events typically cut annual economic growth by 1–2 percentage points per capita…READ ON

Floods less likely to be severe when cyclones hit dry land before monsoons, finds study

Flooding in India’s river basins is more likely when the rainfall-embedded cyclone system encounters moisture-saturated land during monsoons and immediately after the monsoon, says a recent study.

Study finds that when cyclones occur before monsoons, the soil is very dry and therefore the rains don’t result in floods.

Cyclone-linked rainfall and the existing soil moisture levels of the basin, shape severity of floods, says the study by Indian Institute of Technology (IIT)-Gandhinagar researchers Vimal Mishra and Akshay Rajeev. The scientists examined the impact of tropical cyclones on flooding in four major Indian river basins (Subarnarekha, Brahmani, Mahanadi and Vamshadhara) in India’s east coast covering cyclones from 1981 to 2019…READ ON

Understanding Resilience History

We are living in the age of the Fourth Industrial Revolution. Some changes can be easily noticed. Business disruption, caused by the technologies that underpin the revolution, are visible across all industries. Other impacts, such as a risk of social inequality, are subtler, and their effects will not be apparent for some time.

Four hundred years ago, in the middle of another transformative period now referred to as the Scientific Revolution, a simple concept called resilience appeared. Today, resilience is a significant area of interest in a range of fields, from human psychology and ecological systems, to organisational performance and natural disasters.  Understanding the evolution of the concept is the first step towards building a ’no regrets resilience strategy’, essential for both personal and societal sustainability and thriving in the face of complex disruptions and disturbances. 

The Global Resilience Collaborative’s Resilience Case Files is the first in a series of tools designed to help those seeking to define their future through resilience in the face of complex disruptions resulting from the Fourth Industrial Revolution…WATCH VIDEO
