It’s often more rational for people in disaster-prone areas not to move

Over at The Atlantic Cities, Prof. Harvey Moltoch has a good piece titled “Why Residents of Disaster-Prone Areas Don’t Move.” In it, he discusses some of the economic and emotional reasons why people choose to stay in vulnerable areas, even after suffering the devastating effects of disasters like Superstorm Sandy.

Consider, for example, that people are consumers of space in ways that go beyond having houses, apartments, back-yard gardens, and a place for the RV. They have friends, family and obligations nearby. Location, especially residential location, is the node around which people manage life with routines, like having specific shopping habits close to home. Even when they can be financially “made whole” in an offer to retreat, residents may not want the deal. Hence there are “hold-outs” who resist even robust financial inducements. Private developers trying to assemble large parcels know this all too well: people often want to remain for reasons that money can’t overcome.

Given the recent string of disasters that have occurred in the last few weeks – including earthquakes in Pakistan and the Philippines and massive tropical storms in China, India, and Japan – it is logical that people would want to understand the motives of those who choose to remain in harm’s way, despite the inherent risks; this is particularly true, given that each of these areas has been hit by similar destructive disasters in the past.

While Prof. Moltoch’s post provides valuable insight into this issue, it ignores a lot of other key factors that play into the decision. Moreover, it is largely applicable only to the developed world. What may seem economically rational to a person living in the Korail slum of Dhaka does not necessarily comport to Western standards, and vice versa.

In many areas, government regulations and economic structures may create incentives for individuals and businesses to build in these high risk areas. Both the presence of certain initiatives – like the heavily indebted federal flood insurance program – and the absence of others – such as a requirement to incorporate climate change projections into infrastructure planning – can incentivize people to build in areas where, if externalities were properly accounted for, it would not make economic sense for development.

One can understand the reticence of taxpayers to effectively subsidize such unsustainable development projects. Accordingly, it’s not surprising to see people make comments like “we ALL pay for their stupidity to remain in place,” which one person said in response to Prof. Moltoch’s piece. Yet, this mindset ignores the fact that, for many people (particularly in the developing world), staying in disaster-prone areas is actually the rational decision.

Given the threats posed by climate change, particularly that of sea level rise for low-lying areas, it’s common to hear about the need to resettle large populations of people from, say, Kiribati or Bangladesh. Yet, as we frequently see with resettlement programs related to large-scale development projects, people often find themselves worse off than before. The Hirakud dam, India’s first mega-dam, was completed more than 60 years ago; despite this fact, at least 10,000 people affected by the project still have not been rehabilitated fully.

While moving people from disaster-prone areas may minimize their physical vulnerability, it frequently maximizes their social vulnerability and sense of dislocation (PDF). Following major droughts in the 1980s, for instance, the Ethiopian government launched a large-scale, forced resettlement program of famine-affected households. The effort proved to be a catastrophe, and it soon turned into a state-sponsored disaster of its own.

Two vital forms of capital upon which people can draw to enhance their resilience to disasters are a familiarity with the climate/environment and social networks. Forced relocation can upset each of these in significant ways. Following massive flooding on the Zambeze and Limpopo Rivers in 2001 and 2007, the Mozambican government resettled a large number of people (PDF) from the affected flood plains. Unfortunately, these flood-safe regions suffer from recurrent drought; accordingly, many of the people who were resettled actually returned to the flood-prone areas after the disaster ended.

Moreover, forced relocation frequently breaks social bonds and interferes with various forms of social capital, leaving individuals highly vulnerable and prone to exploitation. After Hurricane Katrina, the rate of rape among women living in FEMA trailer camps was 53.6 times higher (PDF) than the rate before the storm. There is also ample evidence that Cambodian and Vietnamese families forced to migrate from their homes have sold their daughters into the sex trade (PDF) in order to generate income.

Lastly, particularly in urban areas, it is essential for poor households to have ready access to economic opportunities. Yet, the majority of formal land that the urban poor can afford is located within the peri-urban fringe, far from the urban core. Accordingly, most poor households will opt to live in marginal areas closer to the city center in order to have easier access to the economic resources upon which their livelihoods depend. This create situations in which slums develop in highly vulnerable, disaster-prone areas, such as the Annawadi slum of Mumbai that Katerine Boo chronicles in Beyond the Beautiful Forevers.

Tap water & the key issues the Drink Up campaign misses

I wrote another guest post for Drink Local. Drink Tap., Inc.™ on the Drink Up campaign and the issues it misses. Check it out at their site. Here’s a snippet:

As other contributors have noted on this blog, bottled water carries a host of negative consequences – one of the most important of these involves issues of inequity. Bottled water tends to cost roughly 240 to 10,000 times per gallon than tap water. This occurs despite the fact that roughly one-third of bottled water is simply packaged municipal tap water.

African-American and Hispanic parents are three times more likely to give their children exclusively bottled water, despite this high cost. They report doing this because they perceive it as being cleaner and safer than tap water (the evidence suggests otherwise). The industry has also sought to position its product as a status symbol. Nestle recently introduced “Resource,” a bottled water for women who are “trendy” and “higher-income.”

Climate change will reduce labor productivity, increase inequality

Last week, an article came out in the journal Nature Climate Change (Climate Central also has a good summary of it) that discussed the likely effects of climate change on labor productivity. The authors examined the effects of heat stress during peak heat stress months in tropical and mid-latitude regions.

They concluded:

We estimate that environmental heat stress has reduced labour capacity to 90% in peak months over the past few decades. ESM2M projects labour capacity reduction to 80% in peak months by 2050. Under the highest scenario considered (Representative Concentration Pathway 8.5), ESM2M projects labour capacity reduction to less than 40% by 2200 in peak months, with most tropical and mid-latitudes experiencing extreme climatological heat stress.

While these findings are new, they mirror earlier work on the effects of climate-related extreme temperatures on income and production. In their 2008 paper (PDF) “Climate Shocks and Economic Growth:Evidence from the Last Half Century,” Dell, Jones, and Olken studied temperature and precipitation data from 1950-2003 in order to determine the effects of extreme temperature and precipitation on a country’s economic performance.

Their results suggested that each 1◦C increase in average temperatures in any given year tends to reduce economic output by 1.1%; however, this effect only appeared in low-income countries. Using this historical relationship, they projected the long-term effects of global warming on economic output in poor countries, based on mid-range climate projections through the end of the century. In the key paragraph of paper (page 23), they note:

“With a 10-year adaptation horizon, the median growth rate among poor countries appears 0.6 percentage points lower through 2099 compared to the case of no warming. Extrapolated over 100 years, this implies that the median poor country’s income will be about 50% lower than it would be had there been no climate change.”


The authors found no similar effect for high-income countries, suggesting that climate change will further exacerbate global economic inequality significantly. The central cause for this result is the differing natures of the economies in high- and low-income states. According to the World Bank, agriculture accounted for 26.2% of GDP for low-income countries from 2008-2010. For high-income countries, this number was just 1.3%.

Economies in low-income countries are heavily dependent on natural resources, particularly agriculture, implying that workers in these areas are directly susceptible to direct effects of higher temperatures and changes in precipitation. The negative effects will stretch beyond just agriculture, however. Climate change will likely negatively effect forestry and fisheries, among other sectors. In the least developed countries (LDCs), revenues derived from natural resources account for 20.3% of GDP. The most developed countries – the 27 members of the OECD – derive just 1.5% of their GDP from resource rents.

Climate change will emerge as an environmental justice issue and will continue to threaten the fragile human and economic development of the world’s poor. Low-income states will suffer the most from climate change, despite the fact that they have done the least to contribute to it. LCDs emitted just 0.25 metric tons of CO2 annually from 2007-2009; high-income states, in contrast, accounted for 11.97 tons of CO2 emissions during this period – nearly 48 times higher.

Clearly, climate change will have major economic and development impacts. But its most serious, perverse impact will be moral.
