Forecast: Countries could backslide into poverty

Part 2: The spread of disease

The next morning Santos and his colleagues would test the insects with pesticides so the state could adapt to any signs of resistance.

The economic cost of malaria is high. The disease is both a cause and an effect of poverty.

In Africa, where it is most rampant, the World Bank estimates epidemics cost the continent $12 billion a year and slow economic growth by as much as 1.3 percent. In the countries that are hardest hit, even simple prevention measures like $5 bed nets — let alone anti-malarial drugs or robust mosquito control — are out of reach for the very poor.

“Where malaria prospers most, human societies have prospered least,” wrote Jeffrey Sachs, director of the Earth Institute at Columbia University, and Pia Malaney, an economist at Harvard, in Nature. “The extent of the correlation suggests that malaria and poverty are intimately related.”

The health care systems in richer countries are likely to be able to dampen the effects of climate change on the spread of disease, but countries in the third world will suffer the full consequences.

“Restrictions on the movement of goods could also be a source of economic and political turmoil,” wrote John Podesta and Peter Ogden of the Center for American Progress, a progressive think tank, in the Washington Quarterly.

“Pandemic-affected countries could lose significant revenue from a decline in exports due to limits or bans placed on products that originate or transit through them. The restrictions placed on India during a plague outbreak that lasted for seven weeks in 1994 cost it approximately $2 billion in trade revenue. Countries that depend on tourism could be economically devastated by even relatively small outbreaks.”

Vector-borne diseases will spread through the highlands of poor countries like Kenya, Uganda and Zimbabwe, and will chip at the progress made by emerging economies.

Subhrendu Pattanayak, an economist at RTI International, a nonprofit research corporation in North Carolina, argues that countries in the Amazon need to prevent deforestation if only to blunt the cost to the economy as malaria rises due to climate change.

“Sure we have an Africa story,” he said. “But there are countries like Brazil and India and Indonesia and Malaysia, which are not so poor, where the consequences could be pretty serious.”

In the battle against disease and climate change, Pattanayak said, it’s the middle-income countries that have the most to lose.

“Some of these are about to take off and become major global powers,” he said. “But they’re still susceptible to these outbreaks. That’s what I would worry about.”
