Strengthening urban resilience to natural disasters
Given the global warming problem, what will the world look like, say, in 100 years? Recently, a group of researchers from the University of Chicago and the University of California, Berkeley, explored how global temperatures, sea level, rainfall patterns, etc, have affected human lifespans, crop yields, violent crimes and productivity in the past; and then estimated the impact of rising temperature on human behaviour, health and the economy in the coming 100 years.
They pointed out that by 2100, within each year, there would be more than nine million deaths due to global warming, with the affected areas spread unevenly. In the northern hemisphere, the southern warmer regions such as the southwestern United States and India would suffer the most, because the energy cost of air-conditioning would continue to rise, but the crop yields there would not be satisfactory.
The study also mentioned that the GDP of India would probably fall by 20 percent by that time. Meanwhile, some places would be less affected, mainly in the north where the existing climate was relatively cold…
Some Disaster Prevention Spending Reaps Higher Rewards
Federal disaster mitigation spending provides substantial returns for at-risk states and communities, in some cases nearly $7 in avoided disaster costs for every $1 spent before a flood, fire, windstorm or earthquake strikes.
But the value of mitigation spending is not even across all states, nor is it consistent across disaster type, according to a new Pew Charitable Trusts analysis of data collected by the National Institute of Building Sciences.
In fact, some of the greatest returns associated with disaster mitigation are in the Great Plains, Midwest and Ohio Valley, while coastal states like Florida, Texas and California see lower benefit-cost ratios on average, according to Pew…
