It's understandable to want to shield children from the impacts of disasters. But research suggests that they should be given a voice in disaster planning and a role in reducing the risks.
Hurricane Harvey flooded one-third of Houston and displaced more then 30,000 people in the region.
After disasters, communities often push to rebuild as quickly as possible. A public health expert says they should aim higher and fix problems that exist pre-storm.
Fallen trees and power lines are two of the main hazards that could have been reduced with better planning for cyclones.
After Cyclone Tracy, you'd expect Darwin of all cities to be ready for the next one. But as the clean-up after Cyclone Marcus continues, it's clear more must be done to increase the city's resilience.

On March 11, 2011, a nuclear disaster struck Japan. Translated testimony by the power plant's manager reveals how close the world came to a greater catastrophe -- and how much there is to be learned.

To address environmental degradation, including climate change, it is essential to take into account human rights and migration. Hybrid international law and regional thinking are both essential.
People in the U.S. and the Caribbean share vulnerability to climate change-related disasters, but only in the Caribbean is the public truly worried. Why?
New research suggests politics and risk perception may explain why the US and Caribbean see climate change so differently, though both places are ever more vulnerable to powerful hurricanes.
Paris “under water” and other European cities facing drastic climate change should trigger planners to think urban spaces differently.
In the future, Europe will suffer from more heat waves as well as extreme rainfall, presenting new challenges for planners and health care services. Building resilient cities can help.
Puerto Rico’s power utility, PREPA, has been decimated by years of scarcity and bad management. But will privatizing it really turn the lights back on for Puerto Ricans?

Many Puerto Ricans are happy to see their broke power utility sold off to whoever can get the lights turned back on. But privatizing the island's energy grid may bring more problems than relief.
Fires break out across San Francisco after the April 18, 1906 earthquake.
According to current forecasts, California has a 93 percent chance of an earthquake with magnitude 7 or greater occurring by 2045. Early warning systems, now in development, could limit casualties and damage.

While the Montecito, California mudslides took 20 lives, landslides kill far more people in developing countries. Tighter construction standards and early warning systems could help reduce their toll.
Australians need better planning to cope with extreme heat.
Australia's scorching summers aren't just inconvenient: heatwaves are deadly. Yet new research has found many vulnerable people don't have a plan for extreme heat.
As many as 20 people are dead and dozens missing following the Southern California mudslides.

In response to mudslides that have killed at least 20 people in Southern California, a geologist calls for more resources to study and map landslide hazards so residents can understand the risks.
Hurricane Maria’s destruction may have led to many hundreds more deaths than originally estimated.
The governor of Puerto Rico has ordered a recount of the official death toll for Hurricane Maria. The real number is likely higher by the hundreds. What happened?
People wait to get evacuated in Sukadana village, near Mount Agung, a volcano on the highest alert level, in Bali, Indonesia.
Floods and natural disasters can be highly traumatic for children.
If more people live in the Adelaide Hills, they are more likely to be exposed to bushfires.
What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
