Resilient transport investments: a climate imperative for Small Island Developing Countries

Franz Drees-Gross's picture


Transport in its many forms – from tuk-tuks in Thailand to futuristic self-driving electric cars – is ubiquitous in the lives of everyone on the planet. For that reason, it is often taken for granted – unless we are caught in congestion, or more dramatically, if the water truck fails to arrive at a drought-stricken community in Africa.

It is easy to forget that transport is a crucial part of the global economy. Overall, countries invest between $1.4 to $2.1 trillion per year in transport infrastructure to meet the world’s demand for mobility and connectivity. Efficient transport systems move goods and services, connect people to economic opportunities, and enable access to essential services like healthcare and education. Transport is a fundamental enabler to achieving almost all the Sustainable Development Goals (SDGs), and is crucial to meet the objectives under the Paris agreement of limiting global warming to less than 2°C by 2100, and make best efforts to limit warming to 1.5°C.

But all of this depends on well-functioning transport systems. With the effects of climate change, in many countries this assumption is becoming less of a given. The impact of extreme natural events on transport—itself a major contributor to greenhouse gas emissions—often serve as an abrupt reminder of how central it is, both for urgent response needs such as evacuating people and getting emergency services where they are needed, but also for longer term economic recovery, often impaired by destroyed infrastructure and lost livelihoods. A country that loses its transport infrastructure cannot respond effectively to climate change impacts.

​Air transportation – the critical infrastructure when disaster strikes

When disaster strikes, air transport is often the only feasible mode of transportation for first responders and urgently needed relief supplies. Following an earthquake, tsunami or hurricane, most roads, rail tracks and even ports become unusable, as they are blocked for days by debris. Airports, on the other hand, are remarkably sustainable and, within hours, usually become operational again.

The main reason of this sustainability is that runways are on open space where debris of a disaster can be removed quickly. Furthermore, a runway usually suffers remarkable little damage even by a strong earthquake, such as experienced last week in Nepal or in Haiti in 2010. And even if there are cracks and holes in the runway, modern relief aircraft like C-130s can operate safely for some time.
 
However, the challenges of operating relief flights can quickly become overwhelming, especially for airports in developing countries that usually experience only moderate traffic. In Haiti, for example, more than 74 aircraft landed on a single day following the earthquake to unload supplies. Such traffic poses risks in the air; air traffic control, often hampered by inadequate or damaged surveillance installations, can’t cope managing all arriving aircraft. On the ground, where tarmac and taxiways are small, congestion quickly reigns which prevents the arrival of more flights.
