Conflict of Interest in Science

There is a great deal of overlap and integration between government agencies, private corporations including Big Pharm and Big Ag and Big Whatever, university and other research institutions, and the scientist and others who work in these places.

This topic is addressed in the latest episode of the science podcast Ikonokast, which also includes details about a recent minor scandal involving GMO research and squirrels. And maybe bears.

Editing Out Diseases with the Help of Bioengineering

I get a lot of “infographics” and many are quite good. But this medium has become a vehicle for commercial advertising. So, some company comes up with an info graphics, maybe makes a good one, sends it around to the bloggers and such, and thier name, somewhere down there near the bottom, gets around. I don’t mind the commercial aspect too much, but unless I’m able to vet the graphic, I can’t post it, I don’t generally have time or resources to do that, so I therefore ignore them.

But this one I’ll post because it looks interesting and is produced by a university. Also, we often discuss GMOs around here, and this is a handy dandy look at how that community sees itself, from an important perspective, at the moment.

Throughout history, humans have continuously made efforts to heal and eradicate diseases. In early, less modern times, this process was considered both difficult and strenuous, but with the advancement of technology and bioengineering, humans are developing faster, more effective measures for treating and eradicating diseases.

Genetics and Food Security

There is a food crisis sneaking up on us right now. A lot of them, actually. A lot of little one, some big ones. There are always places in the world where food has become scarce for at time, and people starve or move. You’ve heard of the “”Syrian refugee crisis,” and the often extreme reactions to it in Europe and among some in the US. That started out as a food crisis, brought on by human pollution induced global warming in an already arid agricultural zone.

Nearly similar levels of climate change related pressure on agricultural systems elsewhere has led to very different outcomes, sometimes more adaptive outcomes that won’t (at least for now) lead to major geopolitical catastrophes as we have now in the Levant and elsewhere in West Asia. What’s the difference? The difference is how agriculture is done.

Are GMOs a solution? Are GMOs safe, and can the produce a small or medium size revolution in crop productivity? What about upgrading traditional agriculture to “industrial agriculture”?

And speaking of GMOs, what is the latest in GMO research? How should GMOs be regulated, by the method they are produced, or by the novel or altered traits they have? How do we communicate about GMO research and GMO crops? What about labeling?

These and many other questions are addressed ad Mike Haubrich, me, and Anastasia Bodnar talk about “Genetics and Food Security” on the latest installment of the Ikonokast Podcast.

The Coming Food Crisis And What To Do About It

According to the best available research, we are going to have to double food supplies, globally, by 2050. Think about that for a moment. Children born today will be in their 40s at a time that we need to have already doubled food production, yet during the last 20 years we have seen only a 20 percent increase in food supply. Assuming a steady rate of increase in production (which might be optimistic) we should expect to fall far short of demand over the next few decades. This is a problem. The problem is expected to most severely affect poorer people, people in less developed nations, and poor farmers, but if the entire world is double digit percentage points short of food, almost no one is going to get by unscathed. And, at some point, when nearly everyone is seeing some sort of food shortage or extraordinarily high prices, the totally unscathed are going to start looking pretty tasty to the rest of us.

eat-the-rich_11-26-11Also, agricultural production, whether for food or biofuel, has a fairly large Carbon footprint, both by reducing natural Carbon sinks and by using fossil fuels at a fairly high rate. Doubling production of food would presumably involve increasing these effects, unless alternative approaches are developed. So even if we solve the problem of production, we might exacerbate the problem of human caused climate change. Let us not even speak of sea level rise; Over the coming century we expect sea levels to rise sufficiently to flood, either regularly or permanently, some of the most productive agricultural areas in the world, which would seriously dampen efforts to increase productivity.

And water. This will all require more water, when we are facing increasing shortages of water.

How do we address this problem? Will Genetically Modified Organisms (GMOs) save the day? Are there other approaches to quickly increase agricultural output? Can we eat different foods that are less difficult or costly to produce?

Emily_CassidyEmily Cassidy knows some of these answers. Emily is a scientist with with over five years of experience working on land use, agriculture, and the impacts of growing biofuels vis-a-vis developing food crops. She is currently a research analyst with the Environmental Working Group (EWG). Earlier she worked as a scientist with the Louisiana Department of Natural Resources, measuring impacts of coastal activities. Her Master’s degree at the University of Minnesota involved detailed modeling of global food availability, which involved developing a new index to quantify the number of people fed per hectare of cropland. This research was widely disseminated in mainstream media.

Recently, Emily produced a report for EWG that looks at the role of genetically modified organisms (GMOs) in addressing the world’s food supply. You can get the report here. I had a few questions, so I interviewed Emily about this report as well as the larger issue of humans running out of food during the present lifetime of so many of us.

Question: The amount of space, energy, and other resources dedicated to the production of meat is enormous. According to your EWG report, producing meat requires three-quarters of the agricultural land in use. For every one calorie of meat we produce we displace about 10 calories of plant based food. You also note that there is a huge amount of waste in the food stream, with about a third (by weight, about one quarter of the calories) lost. The US tosses closer to 40 percent, and of all the forms of food, a disproportionately large percent of meat is wasted. Having recently purchased, twice in a row (apparently you can fool me twice) “fresh” chicken at my local not-very-good grocery store that was rotten the next day, I was wondering where the waste in the food stream, especially for meat, was concentrated, and if we could help solve this problem by distributing meat primarily in frozen form.

On food waste in the US, especially meat, do you have a breakdown of where the meat is wasted? I wonder if a switch to having almost all meat frozen and sold in frozen form would reduce a lot of waste.

Emily: Meat production takes a massive environmental toll, and when we waste meat, we’re wasting all the resources used to produce it. About half of the meat wasted in the U.S. and Europe is tossed at home. Better meal planning and freezing meat could be a big step to reducing household waste. Although supermarkets have an important role to play in reducing waste, according to the Food and Agriculture Organization, only about 15 percent of meat waste in the U.S. occurs at supermarkets.

Emily’s report pretty much slams GMOs. The report states:

Proponents of GE crops claim that they are essential to “feed the world,” but recent evidence indicates that so far, GE crops have How to feed the world. [GMOs have] not increased crop yields enough to significantly contribute to food security…In recent decades, in fact, the dominant source
of yield improvements has been traditional crossbreeding, and that is likely to continue for the
foreseeable future. Relying on genetic engineering to double food supplies by 2050 would require a huge leap in biotechnology and doubling the recent yield trends of crops.

Question: Are there any examples of GMOs being developed that will help with this that are not just vague promises? In other words, is there any tangible namable project or potential project you know of that would contribute to that “giant leap in biotechnology”?

Emily: “Roundup Ready” corn and soybeans represent over 80 percent of the acreage growing GMOs, so it’s clear that the industry’s focus since the 1970s has been on genetic modification for herbicide tolerance. These crops haven’t improved yields because there are inherent biophysical trade-offs between productivity and pest resistance. This is why I wouldn’t bet the farm on biotechnology generating massive yield improvements. It’s similar to the live-fast die-young principle in evolutionary biology; plants are limited by their resources and can’t be good at everything at once.

Not all forms of genetic modification are created equal. There are some projects which could be promising and aim to modify a plant’s genome to improve the efficiency photosynthesis. But it seems to me that most genetic modifications only see benefits in the short term, until evolution catches up to the new genome. For example, insects have evolved tolerance to Bt crops, and U.S. Farmers have been told to lay off of them.

Where I do see exciting research that could really improve food security is the cross breeding of often ignored “orphan crops.” Just recently a new kind of drought-tolerant bean was bred by combining a modern bean with a variety traditionally grown by communities in the American Southwest. We should focus efforts and funding on improving the yields of nutritious food crops, not crops that mostly go to animal feed and biofuels.

Question: On a related matter, how much does the the nature of the research itself ruin GMOs as a potential source of a modest or even minor agricultural revolution? It seems to me that helping poor farmers to be less poor will always lose to helping big corporations make more money, and the big corporations seem to be doing or funding most of the research. Is this a general pattern for ag research in general? In the old days big government money went into public universities to develop crops, technology, and methods that were available to all. The current system seems different. Is this a problem?

Emily: Universities are increasingly reliant on private industry for agricultural research funding, and companies are a lot more interested in making money than improving the lives of poor people. Private spending for agricultural research is more than twice the public expenditures. Unless public research funding for agriculture improves, the future of our food system will be heavily influenced by companies seeking to make a profit.

Question: I think a lot of people assume that technology will solve many of our big problems, such as food shortages and climate change. People are divided mostly into two groups: GMO Frankenplants will rise out of the ground and take us in the dead of night (I exaggerate slightly), or they will fix the future. You are suggesting, it seems, that neither of these scenarios is likely. Bottom line, what does your report tell us about GMOs and the medium term problem of people, the poor farmers first, not having enough food?

Emily: There’s a myth that I often hear in Washington, that GMOs help the world’s poorest. If you really look into the evidence though, there’s no support for it. That’s why I wrote EWG report, to address ways to help small farmers, which is the real key to helping the world’s poorest. I’m not anti-GMO but I think we should be honest about their contribution to global food security and improving the livelihoods of poor people.

Question: Current research suggests we need to double our food supply by 2050. But we’ve heard that before. In every decade there are predictions about future population growth or future agricultural productivity that suggest catastrophe, and we’ve passed many of those due dates for an expected Malthusian apocalypse. Is this projection different?

Emily: Malthus assumed population growth would continue without limits. We know now that as people have more income, they generally have less children. Another result of people being wealthier us that they demand more meat and dairy. Recent research has shown that population will increase by about 30 percent by 2050, yet demand for crops is estimated to increase by 100 percent. This difference means that demand for meat and dairy is a bigger driver of crop demand than population.. We also have to keep in mind that many countries are starting to adopt biofuels mandates. Tim Searchinger recently estimated that if all countries met their food-based biofuels targets, it would be the equivalent of removing about 30 percent of calories out of the food system. So depending on biofuels mandates, crop production may have to more than double to meet demands.These policies clearly threaten global food security.

~ ~ ~

Emily’s report makes a series of specific recommendations that will close some of that huge gap in productivity vs. demand. She doesn’t mention eating the rich, but she does have a few other worthy suggestions. Eliminating food waste, shifting away from biofuels, and changing diets are all on the menu. So far, GMOs are not. I recommend that you read it and get working on this right away.

GMOs Are Interesting

The podcast for my interview with Anastasia Bodnar is now available HERE. There are also a couple of links there that you might find of interest.

We focuses on the actual process and science of GMOs and spent very little time on the usual issues. I hope many of you find the interview different and refreshing. Total change of pace from the usual yammering, or at least, that was my intent. Also, for those of you who heard the first interview, I assure you, this time the sound quality is excellent!
