Suicide bomb ers are not all alike . Palestinians prepare elaborate martyr videos before their killings and become celebrities afterward, while Iraqi Sunnis kill their fellow citizens in obscurity. In Afghanistan, the suicide bombers have their own distinction: They are known for their ineptness, often blowing themselves up without killing anyone else.

“They’re not efficient,” said Martha Crenshaw, a senior fellow at the Center for International Security and Cooperation (CISAC) at the Freeman Spogli Institute for International Studies. She arrived at Stanford this summer, after several decades of studying terrorism as a professor of government at Wesleyan University in Middletown, Conn.

Afghan suicide bombers tend to be poorer, younger and less educated than suicide bombers elsewhere, Crenshaw said during a recent CISAC seminar. She cited a United Nations report that accused the Taliban of strapping explosives to boys, despite a commitment not to recruit those too young to have facial hair. Promises of motorcycles and cell phones have been used as inducements.

One boy whose mission failed was interviewed by U.N. workers. “He somehow thought he would survive the attack and get to spend the money they had promised him, not quite understanding that he would not be there,” Crenshaw said in an interview following her talk.

In Afghanistan, as elsewhere, the person wearing the explosives belt or driving the car bomb is the least valuable person in the terror group, Crenshaw said. The key people are the bomb maker and the organizer: “They never send the bomb maker with the bomb.” In Israel, security officials target the bomb makers for assassination.

“It’s the organization that decides who’s going to be attacked and when and where and why,” Crenshaw said. “Then they recruit somebody to carry it out. So the person carrying the bomb really is just a foot soldier.”

Afghanistan’s most famous suicide attack happened in 2001, just two days before the 9/11 assault on the United States. Al-Qaida operatives masquerading as journalists preemptively blew up tribal warlord Ahmad Shah Massoud in anticipation that he might aid U.S. troops if they eventually invaded Afghanistan in search of Osama bin Laden.

Today, al-Qaida, the Taliban and Hizb-i-Islami (the group led by Gulbuddin Hekmatyar) aim their suicide attacks at U.S. and Afghan government forces, but the victims are overwhelmingly civilian bystanders, often large numbers of children. Many of the bombers, Crenshaw said, are recruited from religious schools across the border in Pakistan.

The predominant motivation for terrorists to employ suicide attacks is strategic, not religious, according to Crenshaw. One suicide bomber kills many people, a perfect example of what the U.S. military calls asymmetric warfare. According to the United Nations, since the 1980s suicide bombers have been involved in only 4 percent of the world’s terror attacks, but have caused 29 percent of the deaths.

Crenshaw gave her CISAC talk the day of the bloody suicide-bomber attack on Pakistani opposition leader Benazir Bhutto. With some 140 deaths and 500 injuries, it was the deadliest of more than 50 suicide attacks in Pakistan in recent years. Bhutto survived without injury, but if she had died, the volatile country could have come unglued, according to Crenshaw. “It shows you how one major suicide bombing could make a big difference,” she said.

Her interest in terrorism began in graduate school in the late 1960s. Her first book, Revolutionary Terrorism (Hoover Institution Press, 1978), was on guerilla warfare against the French during the Algerian war for independence from 1954 to 1962. It still sells on Amazon, for $100.

How does one research suicide bombers, since most of them, by definition, are dead? “We don’t have very many studies that are based on extensive interviews,” Crenshaw said. The one well-known body of work based on interviews involves failed Palestinian suicide bombers held in Israeli prisons. But the prisoners have told their stories so often that it is difficult to separate truth from imagination, according to Crenshaw.

Scholars of terrorism in general can turn to trial transcripts, databases of newspaper stories or the “Harmony Project” documents captured from al-Qaida and posted online by the U.S. Military Academy at West Point.

But less has been written specifically about suicide bombers. “In Iraq, it’s very difficult to know who they were, even. They’re dead and they’re blown to bits, too,” Crenshaw said. “You might not have a hand with fingerprints, for example. Surprisingly enough, often they do seem to find heads. But still, how do you identify someone in Iraq, where you don’t have a record of who the population is to begin with? There are no identity cards, no nothing. Really, we’re just guessing.”

The predominant motivation for terrorists to employ suicide attacks is strategic, not religious, according to Martha Crenshaw.

Crenshaw’s most recent paper, “Explaining Suicide Terrorism: A Review Essay” (Security Studies, Vol. 16, No. 1, January 2007), relied on the bookstore: She bought and read 13 books about suicide bombers, then produced a review of them all as a guide to other researchers.

CRENSHAW'S RESEARCH AGENDA
Why is the United States the target of terrorism? Crenshaw is answering this question, as a lead investigator with the National Consortium for the Study of Terrorism and Responses to Terrorism at the University of Maryland, a Department of Homeland Security Center of Excellence. Her research focuses on groups that have targeted the United States or its interests since the mid-1960s, placing incidents in context by comparing them with instances in which groups displayed similar anti-American ideas but did not resort to terrorism.
"Contrary to popular belief, only about 10 percent of active terrorist groups have targeted the United States," she says. "You have to get into the local politics to see what's going on" with anti-U.S. terrorism abroad. Such attacks can be aimed at the local regime, she explained.
Crenshaw is also editing a book tentatively titled The Consequences of Counterterrorist Policies in Democracies, to be published by the Russell Sage Foundation which supported the research.
And "The Debate over ‘New' versus ‘Old' Terrorism," a paper Crenshaw presented at the 2007 American Political Science Association meeting, is set to appear in an edited volume. Crenshaw questions common claims that terrorism in recent years has taken on a completely new character, more religious and lethal.
"Terrorism has changed over time, but there is no fundamental difference between ‘old' and ‘new' terrorism," she said. Researchers and policymakers should "ask why some groups cause large numbers of civilian casualties and others do not," she said, "rather than assuming that religious beliefs are the explanation for lethality."

The Bill & Melinda Gates Foundation’s Agricultural Development Program has awarded Stanford University’s Program on Food Security and the Environment (FSE) and a team of collaborators $3.8 million over three years to conduct a quantitative assessment of the effect of biofuels expansion on food security in the developing world. This work will determine how different scenarios of expanded biofuels production in rich and poor countries will affect global and regional food prices, farmer incomes, and food consumption of the poor. In three case-study countries (India, Mozambique, Senegal), it will make a more detailed assessment of the opportunities and pitfalls associated with an array of possible biofuels development scenarios (e.g., using different crops for biofuels production, using marginal land versus highly productive land, etc.). We expect the work will represent the first systematic, detailed effort to address the effects of biofuels expansion on welfare in poor countries and the first available analytic tool for assessing possible biofuels investments in individual developing countries. Project collaborators include FSE, the International Food Policy Research Institute, the Center on Chinese Agricultural Policy, and the University of Nebraska.

Through this grant, the Bill & Melinda Gates Foundation aims to assess how biofuels may affect smallholder farmers in the developing world. This includes assessing both the risks, such as increasing food prices, and the potential opportunities for smallholder farmers to leverage biofuels to boost their productivity, increase their incomes, and build better lives for themselves and their families. The foundation and Stanford University will disseminate the findings widely to inform a broad audience, including policymakers.

FSE is also very pleased to announce a private gift from Lawrence Kemp for further work in the biofuels area. The Kemp gift will be devoted to building a team of faculty and students on campus who will analyze the transmission of global price effects to local markets, provide policy advice and communication on biofuels, and expand the field-level coverage of Stanford’s biofuels work.

In the November 2007 issue of Environment, project collaborators Rosamond L. Naylor (FSE), Adam Liska, Marshall Burke (FSE), Walter P. Falcon (FSE), Joanne Gaskell, Scott Rozelle (FSE), and Kenneth Cassman demonstrate how high energy prices and biofuelspromoting agricultural policy result in higher food prices generally and then examine in detail the potential global effects of biofuels expansion in four countries for four crops—corn in the United States, cassava in China, sugarcane and soy in Brazil, and palm oil in Indonesia. They argue that in each case, the threats to global food security from biofuels expansion likely outweigh the benefits, especially in the short run. This is because in many poor countries these crops play an important role in the diets of the poor and because the poorest in the world typically spend more money on food than they earn in income through farming. They also note that “second generation” technologies such as cellulosic biofuels will likely not play a significant role in biofuels production over the next decade or longer—and thus in the near-term are very unlikely to be the win-win that their proponents suggest. “The ripple effect: biofuels, food security, and the environment” excerpted from Environment, November 2007

The integration of the agricultural and energy sectors caused by rapid growth in the biofuels market signals a new era in food policy and sustainable development. For the first time in decades, agricultural commodity markets could experience a sustained increase in prices, breaking the long-term price decline that has benefited food consumers worldwide. Whether this transition occurs—and how it will affect global hunger and poverty—remain to be seen. Will food markets begin to track the volatile energy market in terms of price and availability? Will changes in agricultural commodity markets benefit net food producers and raise farm income in poor countries? How will biofuels-induced changes in agricultural commodity markets affect net consumers of food? At risk are more than 800 million food-insecure people—mostly in rural areas and dependent to some extent on agriculture for incomes— who live on less than $1 per day and spend the majority of their incomes on food. An additional 2–2.5 billion people living on $1 to $2 per day are also at risk, as rising commodity prices could pull them swiftly into a food-insecure state.

The potential impact of a large global expansion of biofuels production capacity on net food producers and consumers in low-income countries presents challenges for food policy planners and raises the question of whether sustainable development targets at a more general level can be reached. Achieving the 2015 Millennium Development Goals adopted by the United Nations General Assembly in 2000, which include halving the world’s undernourished and impoverished, lies at the core of global initiatives to improve human well-being and equity, yet today virtually no progress has been made toward achieving the dual goals of alleviating global hunger and poverty. The record varies on a regional basis: Gains have been made in many Asia-Pacific and Latin American-Caribbean countries, but progress has been mixed in South Asia and setbacks have occurred in numerous sub-Saharan African countries. Whether the biofuels boom will move extremely poor countries closer to or further from the Millennium Development Goals remains uncertain.

Biofuels growth also will influence efforts to meet two sets of longer-run development targets. The first encompasses the goals of a “sustainability transition,” articulated by the Board on Sustainable Development of the U.S. National Academy of Sciences, which seeks to provide energy, materials, and information to meet the needs of a global population of 8–10 billion by 2050, while reducing hunger and poverty and preserving the planet’s environmental life-support systems. The second is the Great Transition of the Global Scenario Group, convened by the Stockholm Environment Institute, which focuses specifically on reductions in hunger and greenhouse gas (GHG) emissions beyond 2050. As additional demands are placed on the agricultural resource base for fuel production, will ecosystem services (such as hydrologic balances, biodiversity, and soil quality) that support agricultural activities be eroded? Will biofuels development require a large expansion of crop area, which would involve conversion of marginal land, rainforest, and wetlands to arable land? And what will be the net effect of biofuels expansion on global climate change?

Although the questions outnumber the answers at this stage, two trends seem clear: Total energy use will continue to escalate as incomes rise in both industrial and developing countries, and biofuels will remain a critical energy development target in many parts of the world if petroleum prices exceed $55–$60 per barrel. Even if petroleum prices dip, policy support for biofuels as a means of boosting rural incomes in several key countries will likely generate continued expansion of biofuels production capacity. These trends will have widespread ripple effects on food security—defined here as the ability of all people at all times to have access to affordable food and nutrition for a healthy lifestyle—and on the environment at local, regional, and global scales. The ripple effects will be either positive or negative depending on the country in question and the policies in play.
