The terrorist shootings in Paris have brought a new round of attention to issues of immigration, political polarization, religious discrimination and threats to global security. Scholars at Stanford’s Freeman Spogli Institute for International Studies are following the developments and talking about the attacks.

Cécile Alduy, is an associate professor of French literature writing a book on France’s far-right National Front political party and is an affiliated faculty member of FSI’s Europe Center. She is in Paris, where she wrote an opinion piece for Al Jazeera America and spoke with KQED’s Forum. 

David Laitin is a professor of political science and also an affiliated faculty member of The Europe Center as well as FSI’s Center for International Security and Cooperation. His co-authored book, Why Muslim Integration Fails: An Inquiry in Christian-Heritage Societies, examines Muslim disadvantages and discrimination in Europe.

Christophe Crombez is a consulting professor at TEC specializing in European Union politics. And Martha Crenshaw, a senior fellow at FSI and CISAC, is an expert on political terrorism.

How are Parisians reacting to the tragedy?

Alduy: The mood here is of grief, disgust, anger, and fear. We were all in a state of shock: a sense of disbelief and horror, as if we had entered a surreal time-space where what we hear from the news happening in far away places—Iraq, Afghanistan, Pakistan, Nigeria—had been suddenly catapulted here, on our streets, in our everyday. The shock has given way to mourning. Lots of crying, swallowed tears and heavy hearts. But there’s also revolt and determination to not let that get to us and to not let it succeed in reviving internal wounds.

I was surprised by the spontaneous quiet demonstrations and collective mourning happening all over France: that people would go out rather than hide in spite of the fact that two heavy armed gunmen were on the loose. It was such a naturally humane, human, compassionate response. It was a real consolation to witness this getting together, this flame of humanity and solidarity braving the fear and silencing the silencers.  

What can we say about the brothers who allegedly carried out the attack?

Crenshaw: Apparently they are French citizens of Algerian immigrant origin, who had moved into the orbit of French jihadist networks some years ago. They were both known to French and American authorities, just as the 7/7 London bombers were known to the British police.  One had spent time in a French prison for his association with a jihadist network that sent young men to fight in Iraq, and the other is said to have recently trained in Yemen.  In that case, he would almost certainly have come into contact with operatives of Al Qaeda in the Arabian Peninsula (known as AQAP).  AQAP is an extremely dangerous organization in Yemen and abroad.  The U.S. has regarded it as a number one threat for some time – this is the group that sent the infamous Christmas or underwear bomber on a flight to Detroit in 2009.  Its chief ideologue, the American Anwar al-Awlaki, was killed in an American drone strike in 2012. The fact that the terrorists were two brothers also brings to mind the case of the Tsarnaev brothers and the Boston Marathon bombing.  

What are the cultural and societal implications of the shooting?

Alduy: The event highlights a menace that had been rampant, and duly acknowledged by the French government: that of French-born radicalized Muslims going to Syria, Afghanistan or Iraq to be trained as jihadist and then coming back to conduct terrorist attacks on French soil (this was already the case for Mohammed Merah, but he was not part of an Al-Qaeda cell and acted all alone, as did the man who attacked the Jewish Museum in Bruxells). The cultural and societal implication is that we are now talking of being a country at war, with al-Qaida recruiting among us our potential enemies. In other words, France has to come to terms with the fact that its own values, its own political system, and its own people have been shot execution style in the name of the jihad by our own children.

Explain the extent to which Muslims are disenfranchised and discriminated against in France.

Laitin: Our book documents that Muslims, just for being Muslims, face rather significant discrimination in the French labor market. We sent out CVs to employers, comparing two identically qualified applicants, one named Khadija Diouf and the other Marie Diouf. Both were from Senegalese backgrounds but were French citizens and well educated. Marie received a significantly larger number of “call backs.” From a survey, we know that controlling for race, for gender, and for education, Muslims from one of the two Senegalese language communities we study have much lower household income than matched Christians. We connect this finding to that of the discrimination in the labor market. In our book, we search for the reasons that sustain discrimination against Muslims in France. Here we find that the rooted French population prefers not to have Muslims in their midst, and not to have a lot of Muslims in their midst. Tokens are O.K.

Meanwhile, Muslims exhibit norms concerning gender and concerning public displays of religious devotion that are threatening to the norms of the rooted French. We therefore see a joint responsibility of both the French and the immigrant Muslim communities in sustaining what we call a “discriminatory equilibrium”.

Can these shootings be attributed to those inherent tensions?

Laitin: There is no evidence that this discriminatory equilibrium is in any way responsible for the horrendous criminal behavior exhibited in the offices of Charlie Hebdo. There is a viral cult that is attractive to a small minority of young Muslims inducing them to behavior that is inhuman. The sources of this cult are manifold, but it would be outrageous to attribute it to the difficulties that Muslims face in fully integrating into France.

How will the shootings affect the standing of right-leaning political parties that have been gaining traction?

Crombez: I think the shootings in Paris will provide a further boost to the electoral prospects of France's extreme-right, anti-immigrant party, the National Front. Opinion polls in recent months already showed that it could emerge as France's largest political party at the departmental elections in March – as far as vote share is concerned – and that the Front's candidate for the Presidency in 2017 is likely to make it into, but lose, the second round run-off with the candidate of the moderate right, as was the case in 2002. The shootings will only have improved the Front's chances. Even if the election results are consistent with the polls taken prior to the shootings, and the Front doesn't do even better than the polls predicted, the dramatic results are likely to be attributed to the shootings.

And the long-term political fallout?

Crombez: The effects will reverberate throughout Europe. But as time passes and the shootings become but a distant memory, the effects will disappear. I would draw a parallel here with what happened after the Fukushima nuclear plant disaster in Japan in 2011. In the following months Green parties did very well in elections in Europe at various levels, but after a year or so that effect seems to have dissipated. I would expect this to be the case with the shootings also, except if there are more such incidents to follow.

To predict how agriculture will be affected by future climate change, scientists often rely on a single crop model – a computer simulation of how a specific crop’s yield responds to temperature changes. By combining 30 such models into a single study, and comparing each model against data from existing experimental wheat fields around the world, a team of researchers including Stanford professor David Lobell have developed a more powerful and accurate way to predict future wheat yields.

In a new analysis published in Nature Climate Change, the team’s results support previous work suggesting that wheat yields around the world are sensitive to rising temperatures. Using the new method of analysis, the team estimates an average six percent future yield loss for every one degree Celsius rise in global mean temperature.

“Combining 30 models gives us a much greater ability to predict future impacts and understand past impacts,” said Lobell. “This is a clear step forward.”

Lobell is professor of environmental earth system science in the School of Earth Science at Stanford and the deputy director of the Center on Food Security and the Environment. He is a senior fellow at the Stanford Woods Institute for the Environment and at the Freeman Spogli Institute for International Studies.

The estimated six percent yield loss for every degree increase is equivalent to about a quarter of the current volume of wheat traded globally in 2013. Yields at some sites, notably those in Mexico, Brazil, India and Sudan, show simulated wheat yield losses of more than 20 percent - in Sudan’s case, more than 50 percent - under a scenario in which global mean temperature rises by two degrees Celsius.

With higher temperatures also comes an increase in the variability of wheat yields, both by location and between years. More fluctuation in wheat yields could mean greater global price volatility for the staple crop.

Approximately 70 percent of the wheat produced today is grown either on irrigated plots or in rainy regions. The research team accounted for this factor by focusing its simulations on multiple regional-specific varieties of wheat that are commonly grown under these conditions.

The new paper includes several suggestions for avoiding some of the predicted yield losses. For example, some varieties of wheat are more heat tolerant than others, and farmers in the places hardest hit by rising temperatures could switch varieties to capitalize on this heat resistance. The effects of rising temperatures could also be managed, in part, by adjusting sowing and harvesting dates, or changing the way fertilizers are applied to crops.
