World: Gates Foundation spells out the biggest risks to future progress


IF YOU look beyond the rich West, most of which has been in a funk ever since the financial crisis of 2007-08, the world has had an amazing run. Fully 6m fewer children under the age of five died in 2016 than in 1990. At no time before have so a lot of people been free of grinding poverty and ill health. At no time have women been so unlikely to die as a result of giving birth, or to lose a baby to illness.

But the possibility that from presently on long winning streak humanity could be about to trip and fall is preoccupying Bill and Melinda Gates, a pair of self-described “impatient optimists” who run a foundation dedicated to solving the world’s problems. A statement from the foundation published on September 13th suggests that evolution on several fronts may be starting to falter.

For a variety of reasons, from demography to American and European politics, Mr Gates fears that campaigns to eradicate extreme poverty, HIV and malaria are going awry. He as well believes that the rich world has not noticed. The Bill and Melinda Gates Foundation has hitherto been characterised by confidence, particularly about the potential for technological innovation to solve the world’s knottiest problems. So the change of mood is significant. Peter Piot, director of the London School of Hygiene and Tropical Medicine, describes the statement as “a wake-up call”.

Demography is one of the biggest reasons for gloom. Few nations in a terrible mess have a low birth rate (Libya and Venezuela are part the rare exceptions). In general, the poorest parts of the world, with the worst health, have the highest birth rates. In recent decades an enormous fertility gap has opened between these benighted places and everywhere else. It is caused not by women in poor nations having additional children but by women everywhere else having a lot of fewer.

In 1950-55 Africa’s most populous country, Nigeria, had a fertility rate of 6.4 (meaning that a woman could expect to have that a lot of children if she survived through her childbearing years). That was much higher than in Europe or North America, but similar to the biggest nations in Asia and Latin America. In the early 1950s China’s fertility rate was 6.0. India’s was 5.9 and Brazil’s was 6.1. Six decades later a chasm had opened up. In 2010-15 Nigeria’s fertility rate was estimated to be 5.7, whereas Brazil, China and India all had rates below 2.5.

High birth rates put a large strain on nations. They lead to high dependency ratios, meaning that a relatively small adult people must support lots of children. In mostly agricultural societies, farmers must scratch livings from smaller plots on ever less fertile soils. High birth rates as well have an arithmetical result on world averages measuring development. At the same time as lots of children are born in nations that are largely poor and unhealthy, and few in better-off places, the world taken as a whole becomes poorer and sicker. “Just to tread water takes increasing effort,” says Chris Murray, the director of the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, which produced most of the forecasts for the Gates statement.

Date with destiny

Over the next few decades the fertility gap between Africa and the rest of the world is expected to narrow, but only excruciatingly slowly. If UN projections are right it will take 40 years, from the early 2010s to the early 2050s, for the fertility rate in sub-Saharan Africa to fall from the current level of five to below three. The same drop occurred over 25 years in Latin America and the Caribbean, and just 20 years in Asia, beginning in the early 1970s. The people of sub-Saharan Africa, which stands at about 1bn, is expected to reach 2bn in 2046 and 3bn in 2071.

This demographic divergence is a large reason to fear that poverty will stick around. Today 9% of the world’s people are believed to live in extreme poverty—defined as consuming less than $1.90 a day at 2011 purchasing-power parity. About half of those people are under 18. This represents remarkable evolution: in 1990 about 35% of all people were thought to be extremely poor by the same yardstick. But evolution will probably be much slower hereafter.

In the completed quarter of a century, poverty has fallen greatly in Asia and Latin America. In 1990 two-thirds of Chinese people lived in extreme poverty. At the majority recent estimate, which relies on data from 2013, just 2% did. China is responsible for two-thirds of the in general drop in deep poverty between those years. India, Indonesia and Vietnam are as well seeing it gradually disappear. In short, says Homi Kharas of the Brookings Institution, a think-tank in Washington, DC, whose forecasts the Gates Foundation uses, the “large pools of Asian poverty” are drying up.

Sub-Saharan Africa is sadly completely different. Although the share of Africans living in deep poverty is falling, it is not falling quickly enough to outweigh rapid people increase. The number of paupers in sub-Saharan Africa is holding steady at roughly 415m. Half of the world’s poor people are presently thought to be African (though statistics are patchy for some very poor, dysfunctional nations, such as the Democratic Republic of Congo).

The region’s poverty is particularly intractable. This is largely because so a lot of of its paupers live well below the threshold of extreme poverty, meaning it is harder to pull them over that level. It is as well unpredictable. A terrible ruler, a war or a dismal harvest could send poverty rates shooting up. The growing weight of African paupers in the world total makes forecasting tougher. But in general, Mr Kharas expects the share of the world’s people living in extreme poverty to fall to 6% around the mid-2020s, and to remain at that level in 2030.

Ancient evils

Infectious diseases add to the reasons for concern. Controlling them often requires increasing effort and rising levels of spending just to stand still. But for a lot of illnesses that afflict the world’s poorest people, next funding is uncertain. That includes HIV, malaria and the 20 ailments collectively referred to as “neglected tropical diseases” (NTDs), such as lymphatic filariasis, river blindness and sleeping sickness.

The example of HIV is cautionary, says Mr Gates. He fears that Americans and Europeans, lulled by plummeting infection rates in their own nations, and treatment protocols that can keep the disease at bay for decades, think the world battle against HIV is largely won. The term “AIDS-free generation” is being bandied about. But in some poor nations there is a critical risk that infection rates will start to rise.

Tackling HIV requires co-ordinated action on several fronts. The number of people being infected needs to be brought down, for example by promoting behavioural changes such as using condoms. Those by presently infected must be kept alive and healthy, which requires systems capable of delivering anti-retroviral drugs and other care. As time goes on, rising survival rates mean that the number of people with HIV in the people keeps growing. Treating all of them becomes additional difficult and expensive—and poor nations where a lot of people are infected, as in much of Africa, struggle most. If funding cannot keep pace, additional will receive inadequate treatment. The virus will multiply in their bodies. They will become additional infectious and spread the disease further. And they will die young.

The coming years will see the major youth cohorts in Africa’s history. By 2030 the continent will be home to additional than 280m 15- to 24-year-olds. And additional young people means additional sex, says Dr Piot. “If we continue to do what we are doing presently—which is by presently a considerable effort—that is not going to be good enough.”

Malaria, too, has been beaten back in the completed 15 years, but could stage a resurgence. A vaccine is by presently in use in several nations, but its efficacy is limited and it is not from presently on clear how much use it will be in the poorest nations. Drug companies and research foundations are working to develop better ones, but success is some way off. In the meantime, drug-resistant strains could evolve and spread. Without continuing research into new insecticides to use with bednets, says Mr Gates, deaths from malaria could rise again, as high as 1m a year.

He as well worries that a “mood of retrenchment” means that Western nations are losing interest in the poorest parts of the world. At the same time, a lot of developing nations are failing to spend enough of their own money on health care. A new paper in The Lancet, a medical journal, finds that 32 nations in sub-Saharan Africa spend less than 3% of GDP on health. Experts regard 5% as the minimum required to cover the basics.

International aid remains essential. Britain’s government has stuck to a pledge made in 2013 to meet a UN target of spending 0.7% of GDP on aid (Britain and Germany are the only large donor nations to have reached that level). But this target is controversial, not least within the governing Conservative Party. It may not survive a financial pinch caused by Britain’s exit from the European Union.

Hunkering down

Additional broadly, in Britain and elsewhere in Europe, the political case for aid is changing. Governments are presenting it to voters less as a way to help the world’s poorest people and additional as a way to discourage them from trying to migrate to Europe. The European Union has allocated funds to the governments of several nations, inclunding Niger and Turkey, in the hope that they will clamp down on people-smuggling.

And rich nations have taken to inclunding the cost of dealing with the refugees who fetch up on their shores as part of their foreign-aid spending. Between 2014 and 2016 in-country spending on refugees by the 35 mostly-rich members of the OECD has risen from 5% of net aid to 11%. Such spending does little or nothing to help sorghum farmers in Mali or girls in rural Bangladesh.

President Donald Trump has by presently slashed American funding for charities that provide, or even talk about, abortions in other nations. That will probably lead to additional unwanted pregnancies (and additional abortions) since a lot of of those charities as well provide family-planning services. Mr Trump’s proposed budget would slash foreign aid additional generally. Since America is the world’s major aid donor, that would have a large impact.

Cause and effect

Congress is likely to make amendments, but not to the extent that spending actually rises. This would be a change in direction. Under George W. Bush America led the world fight against HIV. Presently, Mr Gates says, “the best case is flat funding to transaction with a larger pool of people.” The foundation’s statement includes projections of the impact of possible cuts to funding for HIV. A cut of 10%, it predicts, could cost 5.6m lives between presently and 2030.

Is all the pessimism warranted? On some indicators, notably maternal mortality, the Gates statement is reasonably sanguine. And better policies in developing nations could do much to improve the lot of their poorest citizens, even without spending additional. India, for example, which Mr Kharas estimates still has 92m people in extreme poverty, could stop frittering money on fuel subsidies and other hand-outs that have mostly gone to the better-off. Sub-Saharan Africa could as well fare a little better than expected. Though a lot of of the region’s governments are weak and corrupt, at least most are stable these days.

The majority hopeful development would be an unexpected decline in birth rates in sub-Saharan Africa. Demographers have been caught out before. In 1978, for example, the UN estimate a fertility rate for Vietnam of 4.4 in 1995-2000. The rate turned out to be just 2.2. Swift declines in the Middle East as well came as a amaze.

The persistence of very high fertility in the region is something of a puzzle. Some researchers posit cultural explanations. Perhaps the boost to a man’s status from having a lot of children is better than elsewhere, or perhaps communal land-holdings mean that large families continue to be economically beneficial. Additional optimistic, since it suggests better policies could turn things around, is the theory that poor access to modern contraceptives is the major problem.

Look at Bangladesh and Iran, says John Bongaarts of the People Council, in New York. Bangladesh promoted family planning by mobilising village women to preach the virtues of contraception. In the 1980s Iran lurched from pro-natalist policies to promoting family planning. In both nations, the birth rate plunged. Few African nations have done the same (the large exceptions are two highly authoritarian states, Ethiopia and Rwanda, and one well-run democracy, Botswana). “It’s really very frustrating,” says Mr Bongaarts.

Sub-Saharan Africa may muddle its way to a lower birth rate faster than the forecasters estimate, even without help from governments. The region’s cities are growing at a terrific clip of about 4% a year. This increase is often unplanned and messy, and the cities are seldom terribly productive. But urban living is likely to suppress birth rates, all the same. Whereas farmers can put even young children to work pulling weeds and minding goats, city-dwellers tend to find that their offspring add little to household output and, moreover, require expensive schooling. As a result, they seek to have fewer children.

An extra hope for a better next is that medical evolution will be faster than expected. Optimists put their faith in new drugs, better delivery systems and technologies as from presently on unknown: there is even the prospect of a vaccine for HIV, though certainly at least five years away.

From presently on it would be unwise to rely on such breakthroughs, or indeed to imagine that the influence of medical developments on disease is always benign. Jeremy Farrar of the Wellcome Trust, a medical-research charity, warns that untreatable strains of HIV may emerge. Most pathogens from presently on develop resistance to the drugs used to treat them. If drug-resistant strains become common, says Dr Farrar, “imagine controlling a second peak of HIV.”

The real price of the predictions in the Gates statement is less that they give an accurate picture of the world in 2030, than that they provide estimates of what is at stake. Between its optimistic and pessimistic scenarios are the lives and wellbeing of millions of people. And even in the best cases, some nations will make slow evolution. In 2030 the world is highly likely to have at least 490m poor people, according to the Brookings Institution. The forecasts show where there is the greatest potential to save lives and make them better. Between presently and 2030, the difference between the best- and the worst-case scenarios in the deaths of under-fives represents about 7.8m lives, according to the IHME. For maternal deaths the difference is 377,000.

The statement as well highlights the biggest risks to evolution—namely, the control of infectious diseases. If HIV or malaria comes roaring back, the impact will be felt very quickly. Worryingly, the better the evolution against a disease, the harder it is to motivate people and governments to keep going. An anti-malaria campaign in the 1950s and 1960s is instructive. Next early success donors became complacent and the disease rebounded. One of the statement’s most significant messages, says Dr Farrar, is that “we have choices to make”.

Peak progress

Belief in the efficacy of aid, which reached a high point during the “Make Poverty History” campaign in 2005, has been hard to reignite next the financial crisis. Rich nations and their citizens are increasingly looking inwards. They seem pessimistic about their own prospects and less inclined to devote much thought and effort to those of others. From presently on the completed 15 years’ evolution was built not only on investment , but on optimism, both in poor nations and rich ones. This generation has gained greatly from the generosity and resolve of the previous one. It remains to be seen whether the next one will be as fortunate.
