In the Pacific, climate change means trying to expect the unexpected

Chris Bennett's picture

I was reflecting on the saying that “ignorance is bliss” as our plane was landing in Tuvalu, a small island nation in the South Pacific. We had been advised that portions of the recent runway resealing was failing in a number of locations, but it was the video below—showing the runway ‘floating’ under the weight of someone walking on it—that was particularly disconcerting.  Runways are supposed to be solid!

Tuvalu has regularly been called the ‘canary in the coal mine’ when it comes to climate change. The country is comprised of three reef islands and six coral atolls.  With the maximum elevation of 3-4 m, and sea level rise of some 5 mm/year, it is already at a risk of a range of climate change challenges. Now we have a new one: runway failure from beneath caused by what appears to be a combination of very high (‘king’) tides and increased rainfall.

Gender equality hits the highway in Northern Brazil

Young women, some still girls, await long-haul truck drivers that stop by a gas station in the State of Tocantins, located in the North region of Brazil. Here, impoverished women and girls look to get extra cash in exchange for sex, a phenomenon seen on a daily basis in small towns along the federal highway BR-153. The high dropout rate of girls and gender-based violence are commonplace there. While better road infrastructure brings more economic opportunities to the region, higher road traffic and activity can also increase social risks like gender-based violence.   
 
A World Bank’s multisectoral project in Tocantins seeks to improve efficiency of road transport, in particular, state and rural road network, and to support institutional strengthening in the following five sectors: public administration, agriculture, tourism, environment, and education. While the project does not include any roadwork specifically on the highway BR-153, it aims at reducing existing risk of gender-based violence along the highway as part of the education component of the project.  
 
Schools play an important role in building respectful relations between girls and boys, challenging gender-based stereotypes and combatting discrimination that contributes to violence against women and girls. Accordingly, based on the level of the dropout rate and violence statistics, six high schools along BR-153 were selected to host a pilot initiative to improve awareness of gender-based violence and in the area.

Urban transport: Lagos shows Africa the way forward (again)

With a metropolitan population approaching 23 million, Lagos is the economic engine of Nigeria and one of the largest cities on the African continent. Rapid growth, unfortunately, has come with a myriad of urban transport challenges. To get around, most residents rely on the thousands of yellow mini-buses that ply the streets—the infamous "Danfos"—and on a growing supply of three-wheelers. These limited options, combined with endemic congestion, make commuting in Lagos a slow, unreliable, and expensive endeavor.
 
But this entrepreneurial city cannot afford to be stuck in traffic. Things started moving in 2008, when Lagos introduced Africa's first Bus Rapid Transit (BRT) corridor with technical support from the World Bank under the Lagos Urban Transport Project. The corridor was referred to as BRT-lite, a local adaptation that did not apply all the "classical" features of a BRT (level loading, fancy stations) but was well integrated with the local environment and became immediately successful. In fact, the operator was able to recoup its capital investment in the bus fleet in 18 months even without banning competitor services. The BRT services demonstrated that improving the erstwhile chaotic system was indeed possible.
 
Building on this success, Lagos has taken steps to improve and expand the reach of the BRT. The Second Lagos Urban Transport Project (LUTP2), supported jointly by the World Bank and the French Development Agency, provided about $325 million in 2009 toward building a 13-km extension of the BRT corridor between Mile 12 and the satellite town of Ikorodu. In addition to the BRT infrastructure, the project financed the rehabilitation and widening of the road from four to six lanes, the construction of pedestrian overpasses, a bus depot, terminals, a road bridge, measures to enhance flood resilience, as well as improved interchange and transfer facilities.

What El Niño has taught us about infrastructure resilience

The rains in northern Peru have been 10 times stronger than usual this year, leading to floods, landslides and a declaration of a state of emergency in 10 regions in the country. Together with the human and economic toll, these downpours have inflicted tremendous damage to transport infrastructure with added and serious consequences on people’s lives.

These heavy rains are blamed on El Niño, a natural phenomenon characterized by an unusual warming of the sea surface temperature in the central and eastern equatorial Pacific Ocean. This phenomenon occurs every two to seven years, and lasts about 18 months at a time. El Niño significantly disrupts precipitation and wind patterns, giving rise to extreme weather events around the planet.

In Peru, this translates into rising temperatures along the north coast and intense rainfall, typically shortly before Christmas. That’s also when “huaicos” appear. “Huaico,” a word that comes from the Quechua language (wayq’u), refers to the enormous masses of mud and rocks carried by torrential rains from the Andes into rivers, causing them to overflow. These mudslides result from a combination of several natural factors including heavy rains, steep slopes, scarce vegetation, to name a few. But human factors also come into play and exacerbate their impact. That includes, in particular, the construction of human settlements in flood-prone basins or the absence of a comprehensive approach to disaster risk management.

This year’s floods are said to be comparable to those caused by El Niño in 1997-1998, one of the largest natural disasters in recent history, which claimed the lives of 374 people and caused US$1.2 billion worth of damages (data provided by the Peruvian National Institute of Civil Defense).

In India, this transport engineer is racing toward the future… with German supercars

Harsh, a civil engineer from Surendranagar, the western State of Gujarat in India, proudly has a collection of supercars recently delivered from Germany. They are all brand new with sleek designs, glossy paint, and fully loaded with state-of-the-art features. One of them is a 600 horse-power monster, another is the first of its kind in India.
 
Without further ado, let's see what he has...
