Crisis in the Drylands

Sound economic solutions, not military ones, offer the most reliable route to peace for undeveloped nations

The vast region of deserts, grasslands and sparse wood­lands that stretches across the Sahel, the Horn of Africa, the Middle East and Central Asia is by far the most crisis-ridden part of the planet. With the exception of a few highly affluent states in the Persian Gulf, these dryland countries face severe and intensifying challenges, including frequent and deadly droughts, encroaching deserts, burgeoning populations and extreme poverty. The region scores at the very bottom of the United Nations’s Index of Human Development, which ranks countries according to their incomes, life expectancy and educational attainments.

As a result of these desperate conditions, the dryland countries are host to a disproportionate number of the world’s violent conflicts. Look closely at the violence in Afghanistan, Chad, Ethiopia, Iraq, Pakistan, Somalia and Sudan—one finds tribal and often pastoralist communities struggling to survive deepening ecological crises. Water scarcity, in particular, has been a source of territorial conflict when traditional systems of land management fail in the face of rising populations and temperatures and declining rainfall.

Washington looks at many of these clashes and erroneously sees Islamist ideology at the core. Our political leaders fail to realize that other Islamic populations are far more stable economically, politically and socially—and that the root of the crisis in the dryland countries is not Islam but extreme poverty and environmental stress.

The Washington mind-set also prefers military approaches to developmental ones. The U.S. has supported the Ethiopian army in a military incursion into Somalia. It has pushed for military forces to stop the violence in Darfur. It has armed the clans in the deserts of western Iraq and now proposes to arm pastoralist clans in Pakistan along the Afghan border.

The trouble with the military approach is that it is extremely expensive and yet addresses none of the underlying problems. Indeed, the U.S. weapons provided to local clans often end up getting turned on the U.S. itself at a later date. Tellingly, one of the greatest obstacles to posting the proposed peacekeeping troops to Darfur is the lack of a water supply for them. Given the difficulty of finding water for those 26,000 soldiers, it becomes easier to understand the severity of the ongoing and unsolved water crisis facing the five million to seven million residents of Darfur.

Fortunately, much better solutions exist once the focus is put squarely on nurturing sustainable development. Today many proven techniques for “rainwater harvesting” can collect and store rain for later use by people, livestock and crops. In some areas, boreholes that tap underground aquifers can augment water availability; in others, rivers and seasonal surface runoff can be used for irrigation.

Such solutions may cost hundreds of dollars per household, spread out over a few years. This outlay is far too much for the impoverished households to afford but far less than the costs to societies of conflicts and military interventions. The same is true for other low-cost interventions to fight diseases, provide schooling for children and ensure basic nutrition.

To end the poverty trap, pastoralists can increase the productivity of livestock through improved breeds, veterinary care and scientific management of fodder. Often pastoralists can multiply their incomes by selling whole animals, meat products, processed goods (such as leather) and dairy products. The wealthy states of the Middle East are a potentially lucrative nearby market for the livestock industries of Africa and Central Asia.

To build this export market, pastoralist economies will need help with all-weather roads, storage facilities, cell phone coverage, power, veterinary care and technical advice, to mention just a few of the key investments. With crucial support and active engagement of the private sector, however, impoverished dryland communities will be able to take advantage of transformative communications technologies and even gain access to capital from abroad.

Today’s dryland crises in Africa and Central Asia affect the entire world. The U.S. should rethink its overemphasis on military approaches, and Europe should honor its unmet commitments of aid to this region, but other nations—including the wealthy countries of the Middle East and new donors such as India and China—can also help turn the tide. The only reliable way to peace in the vast and troubled drylands will be through sustainable development.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
