How to protect metro systems against natural hazards? Countries look to Japan for answers

The concentration of population in cities and their exposure to seismic hazards constitute one of the greatest disaster risks facing Peru and Ecuador. In 2007, a magnitude 8.0 earthquake along the southern coast of Peru claimed the lives of 520 people and destroyed countless buildings. The most recent earthquake in Ecuador, in 2016, left more than 200 dead and many others injured.
 
Of course, these risks are not exclusive to Latin America. Considered one of the most earthquake-prone countries in the world, Japan has developed unparalleled experience in seismic resilience. The transport sector has been an integral part of the way the country manages earthquake risk— which makes perfect sense when you consider the potential consequences of a seismic event on transport infrastructure, operations, and passenger safety.

São Paulo and Mumbai: Improving Mass Transit in Two BRIC Megacities

Mumbai and São Paulo are two mega metropolitan regions (MMR and SPMR) in the BRICs with about 20 million inhabitants each. They are the economic engines of their respective countries and act as a magnet for rural, low-income populations seeking employment opportunities, growing at a rate that puts tremendous pressure on their transport infrastructure and other public utilities.

As population and income rise, car and motorcycle ownership quickly increased in both megacities while mass transit is not developing fast enough, with serious consequences on traffic congestion, accidents and pollution. São Paulo has 150km+ traffic queues daily and losses of productivity, wasted fuel, health impacts and accidents estimated at around 2% of Brazil’s GDP in 2013, with three fatal deaths daily in motorcycle accidents alone. Mumbai, in addition to all-day road traffic jams, have an astounding six deaths daily from riders hanging and falling from packed trains which circulate with open doors to avoid reducing carrying capacity. The city comes to a standstill when the rail right-of-way is flooded by heavy monsoon rains. 

Access to jobs and basic services in both mega-cities is extremely difficult – particularly for the poor, who often live far from major employment centers. The two cities need to act quickly and take drastic measures to improve mobility and access... But this is easier said than done: expanding the transport infrastructure in these megacities requires careful planning, massive investment,  and may also involve relocating large numbers of people and businesses.
