Turkey Tries to Leverage the Syrian Refugees

You may recall that the EU is paying Turkey a fairly large amount of money to effectively warehouse 3.5 million refugees from the Syrian civil war, rather than letting them head into Europe. A story in today's Guardian reports that Turkey's Prime Minister Binali Yıldırım has threatened to let those people go if the upcoming Syrian peace talks include the Kurds, whom the Turkish government considers to be terrorists.
A sixth round of UN-sponsored Syrian talks to find a political solution for the six-year conflict is due to resume in Geneva on Tuesday, and Turkish opposition to any role in the talks for the Kurdish forces, the YPG, is likely to prove one of many stumbling blocks. Turkey regards the Syrian Kurds as inextricably linked to the Kurdish militant organisation, the PKK, which operates inside Turkey.

Speaking after a meeting with Theresa May in London on Monday, Binali Yıldırım said it was possible for Turkey to renege on its agreement with the EU, under which 3.5 million refugees from neighbouring Syria have settled inside Turkey instead of heading for western Europe. 
Insisting Turkey is essential to Europe’s security and had prevented more than 53,000 foreign fighters reaching Syria and Iraq, he said: “We know how much [of] a headache the PKK constitute. If there is tolerance vis-a-vis these organisations in the long term, Europe will be endangering its own.”
The Prime Minister insisted this was not a threat (really??) but he did point that while Turkey has kept the refugees out of Europe, the EU has failed "to stick to a bargain struck in March 2016 in which Turkey would be granted visa liberalisation and cash in return for keeping Syrian refugees within its borders."

The article does not mention whether the fate of those Syrian refugees now in Turkey will be discussed at the Peace talks. One would assume that repatriation to Syria would be the preferred solution, although it is not clear how well they would all be received, nor what resources there would be for them to restart their lives.

A New Form of Election "Fraud" in the US

Michael Wines has a very interesting article in the NYTimes detailing the way in which the attempt to "clean up" lists of voters in several states wound up disenfranchising people who were, in fact, eligible to vote. At issue is something that I have been involved in for a long time--matching records. 

The motivation for cleaning up the voter lists is the requirement of the National Voter Registration Act of 1993 that voter registration officials should make a reasonable effort to cull their lists of people who have died, moved away, are not citizens, or are convicted felons whose rights have not been restored. How do you do that? Largely by comparing lists of people, like those who died or who are felons, with the voter registration list.
Officials do tap databases kept by state vital records agencies, the Social Security Administration and the Postal Service, which has a change-of-address list. But the databases cannot assure matches; some jurisdictions do not collect personal information like Social Security or driver’s license numbers that could make a positive ID easier. 
And the databases themselves have flaws and anomalies. Voters with similar or identical names compound the odds of accidental delisting. A University of Pennsylvania study of 125 million voter registration files from 2012 found that some three million registrants shared a common first name, last name and date of birth. And registrants from groups where a few surnames are commonly used are especially vulnerable to being mistakenly struck from the rolls.
In California, for example, where there is a large Hispanic population, many people have the same surname, and often the same first name, as well. This issue came to my attention many years ago, when I asked by the defense lawyers for Richard Ramirez (the "night-stalker") to analyze why there were too few Hispanics showing up for jury duty in the Los Angeles downtown courthouse. When I examined the program that the county was using to match DMV and Registrar of Voter lists, I discovered that it was throwing out people as matches on the two lists when they were actually different people. This disproportionately affected Hispanics. The county rewrote its code and then handed over the job of matching records to a private firm. How did I know what to look for? My doctoral dissertation involved a matching of birth, marriage, and infant mortality records and I had scoured the literature on matching and had written my own program (see Appendix A in Teenage Marriages if you are interested!).

In the legal system, it is obviously important that a person have a jury of his or her peers, and race/ethnicity is the most important characteristic of "peers" according to rulings by the US Supreme Court. So, inclusion of all jury-eligible persons on a master list from which jurors are chosen is important. In voting, it is important that a person who is eligible to vote not be erroneously thrown off the voting rolls and prevented from voting. As Wines points out, this practice in Florida may actually have been the difference in George Bush winning the presidency in 2000.

Doing a Better Job of Feeding Africans

As the most rapidly growing region on earth, sub-Saharan Africa needs to figure out ways to feed itself, even as it fends off land grabs from outsiders. This week's Economist shows how this could be done--it's all in the DNA. The story is about so-called orphan crops--foods that Africans eat, but which are not cash crops and so they don't get the same kind of attention as do global staples such as wheat, rice, and maize.
The cereals which dominate human diets—rice, wheat and maize—have had their yields and nutritional values boosted over the years by scientific breeding programmes. In the modern era of genomics, they have had their DNA scrutinised down to the level of individual base pairs, the molecular letters in which genetic information is written. They are as far removed, nutritionally, from their ancestors of as little as two centuries ago as those ancestors were from the wild plants which begat them. Orphan crops have yet to undergo such a genetic revolution.
The neglect has two important consequences: (1) these traditional crops, such as cassava, sweet potatoes, lablab beans, water berries, bitter gourds and sickle senna, elephant ears (leafy vegetables) and African locusts (tree-borne legumes) do not have as high a yield per acre as might otherwise be possible; and (2) they are not as nutritious in vitamins as they could be.
Even for adults, a lack of calories and essential nutrients is harmful. For children it can be devastating. Poor childhood nutrition leads to stunting—inadequate bodily development, including the development of the brain. A report published by the World Health Organisation on November 16th suggests that almost a third of Africa’s children, nearly 60m of them, are stunted. And stunted children grow into adults unable to achieve their potential. Researchers at the World Bank reckon the effects of stunting have reduced Africa’s GDP by 9-10% from what it would otherwise be.
Fortunately, African agricultural scientists are at work on these issues. What Nobel Prize-winning Norman Borlaug was able to do for wheat and maize, people like Dr. Robert Mwanga of the International Potato Centre in Uganda are trying to do for these African "orphan" crops. Note that Uganda's International Potato Center is part of a global network of CGIAR centers whose goal is to improve nutrition and food security in developing nations. I had the opportunity to learn about them first hand when I was doing spatial demographic consulting for the Food and Agricultural Organization (FAO) of the UN. The world is clearly a better place for the work they do.

Eating More Animals Isn't Good for Your Health

I recently blogged about the fact that dogs are good for your health. That's because they are good family members. And you wouldn't eat your family members, right? Indeed, my wife and I stopped eating meat more than 30 years ago because we couldn't stand the thought of animals being killed so that we could consume them. And, of course, most people don't have to cope with the agony of doing the killing--they hire others to do that for them. In point of fact, with an increasing global population, especially a population that is ever more urban and affluent, the number of animals being raised for slaughter has increased over time, and that turns out to be bad for our health. 

The bad part is less a function of eating meat itself (although too much meat is not generally very good for you), but rather a function of the diseases that spread between livestock and humans. Making--and trying to fix--this connection is the goal of the One Health approach to life on the planet. A Dutch veterinarian, Thierry van den Berg, recently made the case in a blog post.
The One Health approach acknowledges that population health is dependent on interactions between animal and human diseases. In a globalized world, Humans and animals interact with greater frequency and intimacy. This interaction offers the opportunity for the emergence and spread of disease agents (chemicals, pathogens, etc.) that could adversely impact animal health, human health, or both. A multidisciplinary approach is required to address these questions.
It is reported that 61% of known pathogens can infect multiple animal species and 75% of all diseases that have emerged in the last two decades are of wildlife origin. Newly emerging and re-emerging infections are now recognized as a global problem, and 75% of these are potentially zoonotic.
One of the most significant changes in our society has been the “livestock revolution”, whereby the stock of food animals, their productivity and their trade has increased rapidly to feed the fast expanding and urbanized human population. This has led professionals involved in both animal and public health to recognize “veterinary public health” (VPH) as a key area for their activities to address the human-animal interface.
The reality is that we put ourselves at risk of emerging diseases when we raise ever more livestock for slaughter. And, as I have noted on more than one occasion, our ability to feed a growing population is almost certainly dependent on our eating less meat per person, rather than more. We need to turn things around for the sake of the future human health.

Can We Blame the World's Troubles on Illegal Immigration?

It sounds like it came from Donald Trump, but in fact it was Suu Kyi, the leader of the country of Myanmar, who reportedly told a group of visiting foreign ministers that illegal immigration is a cause of a lot of the problems in the modern world. The story comes from the Associated Press:
Suu Kyi said the world is in a new period of instability as conflicts around the world give rise to new threats and emergencies, citing “Illegal immigration’s spread of terrorism and violent extremism, social disharmony and even the threat of nuclear war. Conflicts take away peace from societies, leaving behind underdevelopment and poverty, pushing peoples and even countries away from one another.”
This seems to be a classic case of blaming the victims, since Myanmar considers its predominantly Muslim Rohingya population to be "illegal immigrants" who have no legal status, despite the fact that Rohingyas have lived in what is now Myanmar for a very long time. 
Myanmar has been widely criticized for the military crackdown that has driven more than 620,000 Rohingya to flee Rakhine state into neighboring Bangladesh. The United Nations has said the crackdown appears to be a campaign of “ethnic cleansing,” and some have called for re-imposing international sanctions that were lifted as Myanmar transitioned from military rule to elected government.
I blogged yesterday about the UN's attempt to enumerate and provide aid to the Rohingya refugees now living in Bangladesh. Myanmar has, for all intents and purposes, violently expelled these people from their own country and is now claiming that they had it coming to them.
