Economists and policymakers are turning more urgent attention to the poorest regions of the planet. Unlike most other parts of the world, these places—in Africa, Central Asia, the Andes and a few other places—seemed to be trapped in poverty. For related reasons, they also seem prone to internal violence and political collapse, a phenomenon known as state failure. The policy question is how best to break the poverty trap.
The regional distribution of these poverty traps is not random. None are in Europe or North America. Asia now has only a few. Most of tropical Africa is in a poverty trap or barely emerging from one, but northern Africa and South Africa are not. What can we learn from these geographic patterns?
As noted in previous columns, the primary problem in most impoverished places is low food productivity, typically as a result of dependence on irregular rainfall rather than irrigation; on weak and easily weathered soils; and often on steeply mountainous, degraded land. Cereal yields are often below one ton per hectare, with complete crop failures every few years, compared with three or more tons per hectare in most developing countries. Food insecurity leads to poor nutrition, high disease burden and hunger-induced violence. The farm households have little or no cash income, leaving them without the means to invest in farm improvements.
The second problem is a heavy burden of disease. The tropics, especially in Africa, are home to lethal and debilitating diseases, such as malaria, soil-transmitted helminthes, filariasis and several others borne by water or insect vectors. In the temperate zones of North America, Europe, China and Japan, those afflictions may be nonexistent or easily controlled, but they are much harder to contain or eliminate in the hot tropics. Malnutrition also raises the disease burden markedly.
The third obstacle is physical isolation. Many impoverished states are landlocked, with no easy access to sea-based trade. And even countries with seaports can face extreme transport problems because of mountainous terrain, large inland populations and overall remoteness from marine world trade routes.
These problems, rooted in geography, set the poverty traps, which manifest in several ways. Because impoverished households must use all of their income to survive, they cannot generate financial savings. They are not creditworthy to borrow. Moreover, they may have to “mine” the local environment unsustainably by depleting the soils, overfishing the lakes and streams, over-hunting bush meat and cutting down forests. Birth rates are high for several reasons: little or no access to family planning and contraception, low child survival, girls not in school, and children regarded as the only old-age security. Many of the poorest regions are also being squeezed by climate change, with increased drought frequency and the spread of tropical diseases. Birth rates stay high for multiple reasons: little or no access to family planning, contraception or education for girls, low child survival and a persistent view that children represent the only security for parents in their old age. Many of the poorest regions are also squeezed by climate change, and suffer increased drought and the spread of tropical diseases.
The political consequences are equally stark. Recent authors have documented how extreme poverty raises the likelihood of violent conflict and a collapse of the state in lawlessness and perhaps anarchy. For example, in his book States, Scarcity, and Civil Strife in the Developing World (Princeton University Press, 2006), political scientist Colin H. Kahl of the University of Minnesota describes the two main paths. First, when deepening poverty leaves the population desperate and the government unable to respond, groups may “self help” by fighting for resources with other groups. Somalia has experienced such a collapse in the past 20 years. Alternatively, if a government takes sides, it may use the state apparatus, even violently, to favor one group against another. The Rwandan genocide was such a phenomenon.

Reply | Report Abuse | Link to thisThe world need to fight together to bring change in an integrated manner. To do so, we need to have in mind that nothing is a stronghold to solve many problems than the horrible way of ruling and injustice the African leaders are responsible for. The most impactful way to save the millions dieing is to change or throw the few rulers and their deadly government.
