Is Industrial Hemp The Ultimate Energy Crop?

By Thomas Prade, Swedish University of Agricultural Sciences

Bioenergy is currently the fastest growing source of renewable energy. Cultivating energy crops on arable land can decrease dependency on depleting fossil resources and it can mitigate climate change.
But some biofuel crops have bad environmental effects: they use too much water, displace people and create more emissions than they save. This has led to a demand for high-yielding energy crops with low environmental impact. Industrial hemp is said to be just that.

Enthusiasts have been promoting the use of industrial hemp for producing bioenergy for a long time now. With its potentially high biomass yield and its suitability to fit into existing crop rotations, hemp could not only complement but exceed other available energy crops.
Hemp, Cannabis sativa, originates from western Asia and India and from there spread around the globe. For centuries, fibres were used to make ropes, sails, cloth and paper, while the seeds were used for protein-rich food and feed. Interest in hemp declined when other fibres such as sisal and jute replaced hemp in the 19th century.

Abuse of hemp as a drug led to the prohibition of its cultivation by the United Nations in 1961. When prohibition was revoked in the 1990s in the European Union, Canada and later in Australia, industrially used hemp emerged again.

This time, the car industry’s interest in light, natural fibre promoted its use. For such industrial use, modern varieties with insignificant content of psychoactive compounds are grown. Nonetheless, industrial hemp cultivation is still prohibited in some industrialised countries like Norway and the USA.

Energy use of industrial hemp is today very limited. There are few countries in which hemp has been commercialised as an energy crop. Sweden is one, and has a small commercial production of hemp briquettes. Hemp briquettes are more expensive than wood-based briquettes, but sell reasonably well on regional markets.

Large-scale energy uses of hemp have also been suggested.

Biogas production from hemp could compete with production from maize, especially in cold climate regions such as Northern Europe and Canada. Ethanol production is possible from the whole hemp plant, and biodiesel can be produced from the oil pressed from hemp seeds. Biodiesel production from hemp seed oil has been shown to overall have a much lower environmental impact than fossil diesel.

Indeed, the environmental benefits of hemp have been praised highly, since hemp cultivation requires very limited amounts of pesticide. Few insect pests are known to exist in hemp crops and fungal diseases are rare.

Since hemp plants shade the ground quickly after sowing, they can outgrow weeds, a trait interesting especially for organic farmers. Still, a weed-free seedbed is required. And without nitrogen fertilisation hemp won´t grow as vigorously as is often suggested.

So, as with any other crop, it takes good agricultural practice to grow hemp right.

Being an annual crop, hemp functions very well in crop rotations. Here it may function as a break crop, reducing the occurance of pests, particularly in cereal production. Farmers interested in cultivating energy crops are often hesitant about tying fields into the production of perennial energy crops such as willow. Due to the high self-tolerance of hemp, cultivation over two to three years in the same field does not lead to significant biomass yield losses.

Small-scale production of hemp briquettes has also proven economically feasible. However, using whole-crop hemp (or any other crop) for energy production is not the overall solution.
Before producing energy from the residues it is certainly more environmentally friendly to use fibres, oils or other compounds of hemp. Even energy in the fibre products can be used when the products become waste.

Recycling plant nutrients to the field, such as in biogas residue, can contribute to lower greenhouse gas emissions from crop production.

Sustainable bioenergy production is not easy, and a diversity of crops will be needed. Industrial hemp is not the ultimate energy crop. Still, if cultivated on good soil with decent fertilisation, hemp can certainly be an environmentally sound crop for bioenergy production and for other industrial uses as well.

Study examines the development of children’s prelife reasoning

Boston University / January 28, 2014 / Cognition

Most people, regardless of race, religion or culture, believe they are immortal. That is, people believe that part of themselves–some indelible core, soul or essence–will transcend the body’s death and live forever. But what is this essence? Why do we believe it survives? And why is this belief so unshakable?

A new Boston University study led by postdoctoral fellow Natalie Emmons and published in the January 16, 2014 online edition of Child Development sheds light on these profound questions by examining children’s ideas about “prelife,” the time before conception. By interviewing 283 children from two distinct cultures in Ecuador, Emmons’s research suggests that our bias toward immortality is a part of human intuition that naturally emerges early in life. And the part of us that is eternal, we believe, is not our skills or ability to reason, but rather our hopes, desires and emotions. We are, in fact, what we feel.

Emmons’ study fits into a growing body of work examining the cognitive roots of religion. Although religion is a dominant force across cultures, science has made little headway in examining whether religious belief–such as the human tendency to believe in a creator–may actually be hard-wired into our brains.

“This work shows that it’s possible for science to study religious belief,” said Deborah Kelemen, an Associate Professor of Psychology at Boston University and co-author of the paper. “At the same time, it helps us understand some universal aspects of human cognition and the structure of the mind.”

Most studies on immortality or “eternalist” beliefs have focused on people’s views of the afterlife. Studies have found that both children and adults believe that bodily needs, such as hunger and thirst, end when people die, but mental capacities, such as thinking or feeling sad, continue in some form.
But these afterlife studies leave one critical question unanswered: where do these beliefs come from? Researchers have long suspected that people develop ideas about the afterlife through cultural exposure, like television or movies, or through religious instruction. But perhaps, thought Emmons, these ideas of immortality actually emerge from our intuition. Just as children learn to talk without formal instruction, maybe they also intuit that part of their mind could exist apart from their body.
Emmons tackled this question by focusing on “prelife,” the period before conception, since few cultures have beliefs or views on the subject. “By focusing on prelife, we could see if culture causes these beliefs to appear, or if they appear spontaneously,” said Emmons.

“I think it’s a brilliant idea,” said Paul Bloom, a Professor of Psychology and Cognitive Science at Yale who was not involved with the study. “One persistent belief is that children learn these ideas through school or church. That’s what makes the prelife research so cool. It’s a very clever way to get at children’s beliefs on a topic where they aren’t given answers ahead of time.”

Emmons interviewed children from an indigenous Shuar village in the Amazon Basin of Ecuador. She chose the group because they have no cultural prelife beliefs, and she suspected that indigenous children, who have regular exposure to birth and death through hunting and farming, would have a more rational, biologically-based view of the time before they were conceived. For comparison, she also interviewed children from an urban area near Quito, Ecuador. Most of the urban children were Roman Catholic, a religion that teaches that life begins only at conception. If cultural influences were paramount, reasoned Emmons, both urban and indigenous children should reject the idea of life before birth.

Emmons showed the children drawings of a baby, a young woman, and the same woman while pregnant, then asked a series of questions about the child’s abilities, thoughts and emotions during each period: as babies, in the womb, and before conception.

The results were surprising. Both groups gave remarkably similar answers, despite their radically different cultures. The children reasoned that their bodies didn’t exist before birth, and that they didn’t have the ability to think or remember. However, both groups also said that their emotions and desires existed before they were born. For example, while children generally reported that they didn’t have eyes and couldn’t see things before birth, they often reported being happy that they would soon meet their mother, or sad that they were apart from their family.

“They didn’t even realize they were contradicting themselves,” said Emmons. “Even kids who had biological knowledge about reproduction still seemed to think that they had existed in some sort of eternal form. And that form really seemed to be about emotions and desires.”

Why would humans have evolved this seemingly universal belief in the eternal existence of our emotions? Emmons said that this human trait might be a by-product of our highly developed social reasoning. “We’re really good at figuring out what people are thinking, what their emotions are, what their desires are,” she said. We tend to see people as the sum of their mental states, and desires and emotions may be particularly helpful when predicting their behavior. Because this ability is so useful and so powerful, it flows over into other parts of our thinking. We sometimes see connections where potentially none exist, we hope there’s a master plan for the universe, we see purpose when there is none, and we imagine that a soul survives without a body.

These ideas, while nonscientific, are natural and deep-seated. “I study these things for a living but even find myself defaulting to them. I know that my mind is a product of my brain but I still like to think of myself as something independent of my body,” said Emmons.

“We have the ability to reflect and reason scientifically, and we have the ability to reason based on our gut and intuition,” she added. “And depending on the situation, one may be more useful than the other.”

The Strategic Sourceror: 3 strategies for boosting sustainability across company operations

3 strategies for boosting sustainability across company operations

Strategic Sourceror on Friday, January 24, 2014

Segregating sustainable product sourcing practices from the larger company strategy and culture can be an easy mistake to make. However, businesses that have long been working to decrease the environmental impact of their procurement processes are well aware that isolated attempts at sustainability are often left behind or discredited over time. What many companies find they need is an emphasis on eco-friendliness that is central to their operations rather than peripheral.
While each firm's approach will differ based on its unique supplier network, some tried and true principles can be adapted and applied across the board. Here are three strategies that can help ensure sustainable sourcing is as effective and fully integrated as possible.

1. Increase communication

In order to avoid sustainability initiatives taking place in a vacuum, they need to be understood across the company. Visibility and communication have been a critical part of the success that Campbell Soup has enjoyed with its green initiatives. Dave Stangis, the company's vice president of public affairs and corporate responsibility, recently gave Sustainable Brands an instructive example of this principle.
"Someone in our communications department aims to tell a better sustainability story from our plant level; he's taken this objective to understand what sustainability work is happening in our 30 manufacturing plants around the world and help communicate that better externally," Stangis told the news source.

Without a solid understanding of sustainable practices internally, it's extremely difficult to communicate these efforts to the public in a cohesive way.

2. Make strategic partnerships

Firms also need to bear in mind that consumers will judge them based on the business relationships they foster. Growing companies looking to make acquisitions, for instance, need to do so with sustainability in mind. According to Sustainable Brands, Campbell chose to acquire Plum Organics, a well regarded company with a reputation for its green mission and employees' involvement in those goals.

3. Consider supplier practices

Lastly, it's key that companies consider the processes of their distribution and sourcing partners as an extension of their own operations. Suppliers need to be factored in when firms calculate their environmental impact and plan for improvements. Sustainability consultant Bill Barry recently began working with book publisher Macmillan to lower carbon emissions across the company's production chain, GreenBiz reported. Barry helped the firm calculate and plan to reduce its direct and indirect environmental impacts by 65 percent over the next five years. He did this by helping Macmillian restructure its paper milling, transportation and other partnerships.

Sustainable supplier management is critical, rather than optional, for companies that are serious about green procurement.

What Killed the Woolly Mammoth?

Professor finds some evidence to support a comet collision as the trigger for the Younger Dryas, which may have contributed to megafauna extinction

By Julie Cohen

Monday, January 27, 2014 - 11:30

Santa Barbara, CA

Could a comet have been responsible for the extinction of North America’s megafauna — woolly mammoths, giant ground sloths and saber-tooth tigers? UC Santa Barbara’s James Kennett, professor emeritus in the Department of Earth Science, posited that such an extraterrestrial event occurred 12,900 years ago.
Originally published in 2007, Kennett’s controversial Younger Dryas Boundary (YDB) hypothesis suggests that a comet collision precipitated the Younger Dryas period of global cooling, which, in turn, contributed to the extinction of many animals and altered human adaptations. The nanodiamond is one type of material that could result from an extraterrestrial collision, and the presence of nanodiamonds along Bull Creek in the Oklahoma Panhandle lends credence to the YDB hypothesis.

More recently, another group of earth scientists, including UCSB’s Alexander Simms and alumna Hanna Alexander, re-examined the distribution of nanodiamonds in Bull Creek’s sedimentological record to see if they could reproduce the original study’s evidence supporting the YDB hypothesis. Their findings appear in the Proceedings of the National Academy of Science.

“We were able to replicate some of their results and we did find nanodiamonds right at the Younger Dryas Boundary,” said Simms, an associate professor in UCSB’s Department of Earth Science.
“However, we also found a second spike of nanodiamonds more recently in the sedimentary record, sometime within the past 3,000 years.”

The researchers analyzed 49 sediment samples representing different time periods and environmental and climactic settings, and identified high levels of nanodiamonds immediately below and just above YDB deposits and in late-Holocene near-surface deposits. The late Holocene began at the end of the Pleistocene 11,700 years ago and continues to the present. The researchers found that the presence of nanodiamonds is not caused by environmental setting, soil formation, cultural activities, other climate changes or the amount of time in which the landscape is stable. The discovery of high concentrations of nanodiamonds from two distinct time periods suggests that whatever process produced the elevated concentrations of nanodiamonds at the onset of the Younger Dryas sediments may have also been active in recent millennia in Bull Creek.

“Nanodiamonds are found in high abundances at the YDB, giving some support to that theory,” Simms said. “However, we did find it at one other site, which may or may not be caused by a smaller but similar event nearby.”

A “recent” meteorite impact did occur near Bull Creek but scientists don’t know exactly when. The fact that the study’s second nanodiamond spike occurred sometime during the past 3,000 years suggests that the distribution of nanodiamonds is not unique to the Younger Dryas.

Sensitivity of carbon cycle to tropical temperature variations has doubled

Sensitivity of carbon cycle to tropical temperature variations has doubled
Jan 26, 2014
Earth

The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed.

The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s.

Professor Pierre Friedlingstein and Professor Peter Cox, from the University of Exeter, collaborated with an international team of researchers from China, Germany, France and the USA, to produce the new study, which is published in the leading academic journal Nature.

Existing Earth System Model simulations indicate that the ability of tropical land ecosystems to store carbon will decline over the 21st century. However, these models are unable to capture the increase in the sensitivity of carbon dioxide to tropical temperatures that is reported in this new study.

Research published last year by Professors Cox and Friedlingstein showed that these variations in atmospheric carbon dioxide can reveal the sensitivity of tropical ecosystems to future climate change.
Taken together, these studies suggest that the sensitivity of tropical ecosystems to climate change has increased substantially in recent decades.

Professor Cox, from the College of Engineering, Mathematics and Physical Sciences said "The year-to-year variation in carbon dioxide concentration is a very useful way to monitor how tropical ecosystems are responding to climate.

"The increase in carbon dioxide variability in the last few decades suggests that tropical ecosystems have become more vulnerable to warming".

Professor Friedlingstein, who is an expert in global carbon cycle studies added: "Current land carbon cycle models do not show this increase over the last 50 years, perhaps because these models underestimate emerging drought effects on tropical ecosystems".

The lead author of the study, Xuhui Wang of Peking University, added: "This enhancement is very unlikely to have resulted from chance, and may provide a new perspective on a possible shift in the terrestrial carbon cycle over the past five decades".

The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers from the Hebrew University of Jerusalem, the US and Australia who have studied the issue and whose work which has just appeared in the journal Science.

Indeed, one could say that the picture is a "cloudy" one, since the determination of the greenhouse gas effect involves multifaceted interactions with cloud cover.

To some extent, aerosols -- particles that float in the air caused by dust or pollution, including greenhouse gases -- counteract part of the harming effects of climate warming by increasing the amount of sunlight reflected from clouds back into space. However, the ways in which these aerosols affect climate through their interaction with clouds are complex and incompletely captured by climate models, say the researchers. As a result, the radiative forcing (that is, the disturbance to Earth's "energy budget" from the sun) caused by human activities is highly uncertain, making it difficult to predict the extent of global warming.

And while advances have led to a more detailed understanding of aerosol-cloud interactions and their effects on climate, further progress is hampered by limited observational capabilities and coarse climate models, says Prof. Daniel Rosenfeld of the Fredy and Nadine Herrmann Institute of Earth Sciences at the Hebrew University of Jerusalem, author of the article in Science. Rosenfeld wrote this article in cooperation with Dr. Steven Sherwood of the University of New South Wales, Sydney, Dr. Robert Wood of the University of Washington, Seattle, and Dr. Leo Donner of the US National Oceanic and Atmospheric Administration. .

Their recent studies have revealed a much more complicated picture of aerosol-cloud interactions than considered previously. Depending on the meteorological circumstances, aerosols can have dramatic effects of either increasing or decreasing the cloud sun-deflecting effect, the researchers say. Furthermore, little is known about the unperturbed aerosol level that existed in the preindustrial era. This reference level is very important for estimating the radiative forcing from aerosols.

Also needing further clarification is the response of the cloud cover and organization to the loss of water by rainfall. Understanding of the formation of ice and its interactions with liquid droplets is even more limited, mainly due to poor ability to measure the ice-nucleating activity of aerosols and the subsequent ice-forming processes in clouds.

Explicit computer simulations of these processes even at the scale of a whole cloud or multi-cloud system, let alone that of the planet, require hundreds of hours on the most powerful computers available. Therefore, a sufficiently accurate simulation of these processes at a global scale is still impractical.
Recently, however, researchers have been able to create groundbreaking simulations in which models were formulated presenting simplified schemes of cloud-aerosol interactions, This approach offers the potential for model runs that resolve clouds on a global scale for time scales up to several years, but climate simulations on a scale of a century are still not feasible. The model is also too coarse to resolve many of the fundamental aerosol-cloud processes at the scales on which they actually occur. Improved observational tests are essential for validating the results of simulations and ensuring that modeling developments are on the right track, say the researchers.

While it is unfortunate that further progress on understanding aerosol-cloud interactions and their effects on climate is limited by inadequate observational tools and models, achieving the required improvement in observations and simulations is within technological reach, the researchers emphasize, provided that the financial resources are invested. The level of effort, they say, should match the socioeconomic importance of what the results could provide: lower uncertainty in measuring human-made climate forcing and better understanding and predictions of future impacts of aerosols on our weather and climate.

Global Warming Alarmists Caught Doctoring '97-Percent Consensus' Claims

Peter Ferrara

(Photo credit: Wikipedia)

Global warming alarmists and their allies in the liberal media have been caught doctoring the results of a widely cited paper asserting there is a 97-percent scientific consensus regarding human-caused global warming. After taking a closer look at the paper, investigative journalists report the authors’ claims of a 97-pecent consensus relied on the authors misclassifying the papers of some of the world’s most prominent global warming skeptics. At the same time, the authors deliberately presented a meaningless survey question so they could twist the responses to fit their own preconceived global warming alarmism.

Global warming alarmist John Cook, founder of the misleadingly named blog site Skeptical Science, published a paper with several other global warming alarmists claiming they reviewed nearly 12,000 abstracts of studies published in the peer-reviewed climate literature. Cook reported that he and his colleagues found that 97 percent of the papers that expressed a position on human-caused global warming “endorsed the consensus position that humans are causing global warming.”
As is the case with other ‘surveys’ alleging an overwhelming scientific consensus on global warming, the question surveyed had absolutely nothing to do with the issues of contention between global warming alarmists and global warming skeptics. The question Cook and his alarmist colleagues surveyed was simply whether humans have caused some global warming. The question is meaningless regarding the global warming debate because most skeptics as well as most alarmists believe humans have caused some global warming. The issue of contention dividing alarmists and skeptics is whether humans are causing global warming of such negative severity as to constitute a crisis demanding concerted action.

Either through idiocy, ignorance, or both, global warming alarmists and the liberal media have been reporting that the Cook study shows a 97 percent consensus that humans are causing a global warming crisis. However, that was clearly not the question surveyed.

Investigative journalists at Popular Technology looked into precisely which papers were classified within Cook’s asserted 97 percent. The investigative journalists found Cook and his colleagues strikingly classified papers by such prominent, vigorous skeptics as Willie Soon, Craig Idso, Nicola Scafetta, Nir Shaviv, Nils-Axel Morner and Alan Carlin as supporting the 97-percent consensus.
Cook and his colleagues, for example, classified a peer-reviewed paper by scientist Craig Idso as explicitly supporting the ‘consensus’ position on global warming “without minimizing” the asserted severity of global warming. When Popular Technology asked Idso whether this was an accurate characterization of his paper, Idso responded, “That is not an accurate representation of my paper.

The papers examined how the rise in atmospheric CO2 could be inducing a phase advance in the spring portion of the atmosphere’s seasonal CO2 cycle. Other literature had previously claimed a measured advance was due to rising temperatures, but we showed that it was quite likely the rise in atmospheric CO2 itself was responsible for the lion’s share of the change. It would be incorrect to claim that our paper was an endorsement of CO2-induced global warming.”

When Popular Technology asked physicist Nicola Scafetta whether Cook and his colleagues accurately classified one of his peer-reviewed papers as supporting the ‘consensus’ position, Scafetta similarly criticized the Skeptical Science classification.

“Cook et al. (2013) is based on a straw man argument because it does not correctly define the IPCC AGW theory, which is NOT that human emissions have contributed 50%+ of the global warming since 1900 but that almost 90-100% of the observed global warming was induced by human emission,” Scafetta responded. “What my papers say is that the IPCC [United Nations Intergovernmental Panel on Climate Change] view is erroneous because about 40-70% of the global warming observed from 1900 to 2000 was induced by the sun.”

“What it is observed right now is utter dishonesty by the IPCC advocates. … They are gradually engaging into a metamorphosis process to save face. … And in this way they will get the credit that they do not merit, and continue in defaming critics like me that actually demonstrated such a fact since 2005/2006,” Scafetta added.

Astrophysicist Nir Shaviv similarly objected to Cook and colleagues claiming he explicitly supported the ‘consensus’ position about human-induced global warming. Asked if Cook and colleagues accurately represented his paper, Shaviv responded, “Nope… it is not an accurate representation. The paper shows that if cosmic rays are included in empirical climate sensitivity analyses, then one finds that different time scales consistently give a low climate sensitivity. i.e., it supports the idea that cosmic rays affect the climate and that climate sensitivity is low. This means that part of the 20th century [warming] should be attributed to the increased solar activity and that 21st century warming under a business as usual scenario should be low (about 1°C).”

“I couldn’t write these things more explicitly in the paper because of the refereeing, however, you don’t have to be a genius to reach these conclusions from the paper,” Shaviv added.

To manufacture their misleading asserted consensus, Cook and his colleagues also misclassified various papers as taking “no position” on human-caused global warming. When Cook and his colleagues determined a paper took no position on the issue, they simply pretended, for the purpose of their 97-percent claim, that the paper did not exist.

Morner, a sea level scientist, told Popular Technology that Cook classifying one of his papers as “no position” was “Certainly not correct and certainly misleading. The paper is strongly against AGW [anthropogenic global warming], and documents its absence in the sea level observational facts. Also, it invalidates the mode of sea level handling by the IPCC.”

Soon, an astrophysicist, similarly objected to Cook classifying his paper as “no position.”

“I am sure that this rating of no position on AGW by CO2 is nowhere accurate nor correct,” said Soon.

“I hope my scientific views and conclusions are clear to anyone that will spend time reading our papers. Cook et al. (2013) is not the study to read if you want to find out about what we say and conclude in our own scientific works,” Soon emphasized.

Viewing the Cook paper in the best possible light, Cook and colleagues can perhaps claim a small amount of wiggle room in their classifications because the explicit wording of the question they analyzed is simply whether humans have caused some global warming. By restricting the question to such a minimalist, largely irrelevant question in the global warming debate and then demanding an explicit, unsolicited refutation of the assertion in order to classify a paper as a ‘consensus’ contrarian, Cook and colleagues misleadingly induce people to believe 97 percent of publishing scientists believe in a global warming crisis when that is simply not the case.

Misleading the public about consensus opinion regarding global warming, of course, is precisely what the Cook paper sought to accomplish. This is a tried and true ruse perfected by global warming alarmists. Global warming alarmists use their own biased, subjective judgment to misclassify published papers according to criteria that is largely irrelevant to the central issues in the global warming debate. Then, by carefully parsing the language of their survey questions and their published results, the alarmists encourage the media and fellow global warming alarmists to cite these biased, subjective, totally irrelevant surveys as conclusive evidence for the lie that nearly all scientists believe humans are creating a global warming crisis.

These biased, misleading, and totally irrelevant “surveys” form the best “evidence” global warming alarmists can muster in the global warming debate. And this truly shows how embarrassingly feeble their alarmist theory really is.

Climate change needs a new kind of scientist

Jan 17 2014

BY Amy Duchelle

Scientific discoveries of recent decades have generated a wealth of knowledge on forests and climate change spanning many different sectors and disciplines. Sustainable development, poverty eradication, the rights of indigenous and local communities to land and resources, conservation of biodiversity, governance, water management, pollution (and all the policies and economic factors related to these sectors) are just some of the issues that scientists studying the relationship between forests climate change must consider.

Such knowledge generation has also laid the foundation for a broader mission to assist in developing integrated solutions. This is not something that we, as climate scientists, have been traditionally trained to do.

It’s clear that developing integrated solutions to such complex problems will require a new kind of climate scientist. A scientist who can think across biophysical and social disciplines. A scientist who can work across scales to engage all members of society in their research. A scientist who can understand the policy implications of their work.

One group that seems particularly enthusiastic to take on such a role is young researchers. In this article, I’ll go through a few examples where young researchers have led the “out of the box” thinking needed to tackle climate change problems.

Interdisciplinary science is at the heart of CIFOR’s Global Comparative Study on REDD+, which aims to inform policy makers, practitioners and donors about what works in reducing emissions from deforestation and forest degradation, and enhancement of forest carbon stocks (REDD+) in tropical countries.

In this study, a diverse group of foresters, biologists, sociologists, economists, political scientists, and anthropologists works together to understand how REDD+ can be implemented effectively, efficiently, equitably, and promote both social and environmental co-benefits.

I help coordinate a component of the study that focuses on measuring the impacts of subnational REDD+ initiatives. Through this part of the study, we have collected data in 170 villages with over 4,000 families in 6 countries: Brazil, Peru, Cameroon, Tanzania, Vietnam and Indonesia.
From 2010 to 2012, we hired nearly 80 undergraduate, Masters and PhD students in Latin America to collect baseline data on livelihoods and land-use at multiple sites across the Amazon. These young scientists have been critical in helping us share project knowledge in different ways.

KNOWLEDGE SHARING
As I was finishing my PhD six years ago, I joined forces with bunch of graduate students who were thinking about how, within our confined academic research environment, we could share knowledge in different ways.

The “knowledge exchange pyramid” (Fig 1) outlines how graduate students can exchange knowledge with local stakeholders during research.

There are three levels of knowledge exchange: (1) information sharing; (2) skill building; and (3) knowledge generation. The black circle represents the researchers while the white circle represents local stakeholders — communities, practitioners, policymakers.

Duchelle, A.E, K. Biedenweg, C. Lucas, A. Virapongse, J. Radachowsky, D. Wojcik, M. Londres, W.L. Bartels, D. Alvira, K.A. Kainer. 2009. Graduate students and knowledge exchange with local stakeholders: Possibilities and preparation. Biotropica 41(5): 578-585.

At the base of the pyramid (the simplest form of knowledge exchange) is information sharing – a primarily one-way transmission of ideas to stakeholders using presentations, brochures and posters. Our experience showed that these tools are particularly appropriate when time is limited, specific facts need to be shared, and information is not controversial.

If your goal is to change attitudes, you need to ensure that stakeholders are given a more active role in interpreting information either through community forums, presentations allowing discussion time, and short workshops.

An example of information sharing is returning research results to local stakeholders. One year after the teams collected baseline data for the Global Comparative Study on REDD+, we went back to all of the research sites and shared the results with the local communities and with the organizations (NGOs and governments) that implement the REDD+ activities.

While many researchers do go back to the places where they collected their data to share results, it has bothered me for years when you go to communities where you know there have been multiple research groups and they say to you, ‘you guys are the first group that come back with the information’.

While many researchers do go back to the places where they collected their data to share results, it has bothered me for years when you go to communities where you know there have been multiple research groups and they say to you, ‘you guys are the first group that come back with the information’.

Sharing results with local stakeholders is an incredibly important learning process and it makes good scientific sense. It allows community members to interpret the information and verify survey data before final analysis. We have found that when a community says ‘that doesn’t make sense, why would it be that way?’, it helps us rethink our interpretation of the data. All it takes is some time, some creativity, and a bit of money.

In the Global Comparative Study on REDD+, I envisaged us returning the results in a pretty conventional way. What blew me away was the innovation of our young researchers – they used art, games and even theatre to make the science interesting and relevant to local communities.
In the second part of the pyramid (slightly more complex knowledge exchange) is skill building, which encourages stakeholders to use knowledge to develop new skills. This is often a response to local demands for skills such as data collection and analysis, grant writing, or manuscript preparation.
While conducting research in Ucayali, Peru forest communities requested training in Global Positioning Systems (GPS) to help them locate and record specific trees in timber harvest areas required by their forest management plans. They also wanted to learn how to measure timber so they could determine a reasonable purchase price (and ensure they weren’t being swindled when it came time to sell the tree trunks or boards).

Skill building activities require more time, resources, and preparation than information sharing but can be incredibly important for building trust with communities. They can also be fun (friendly soccer games are a common feature of fieldwork in Latin America!)
At the highest level of the pyramid is knowledge generation, which includes communities, practitioners or policy makers as partners in different aspects of the research process (one example is “action research”). Together with the graduate researcher, they can create the research questions, implement the research, and analyze and disseminate the results.
While this is the most innovative type of knowledge exchange, it is also the hardest for young researchers to get involved in. Graduate students and their research partners will need to invest a lot of time and energy as well as obtain institutional support.

I know a Brazilian researcher who, before and during her Masters in The University of Florida’s Tropical Conservation and Development Program, developed long-term action research on the ecology of locally important tree species with one remote community in the Amazon estuary. She involved community members in all steps of the research process from setting research priorities, collecting data and training.

After assessing the research findings, community members took several actions. They more than doubled the number of local volunteers collecting data (and diversified to include youth, women, and community leaders), they presented research findings at community meetings and they shared those findings with nearby communities struggling to improve their livelihoods in a sustainable way.
Engaging local stakeholders in research is possible at any level. Young researchers are the ones who can help us think of new and innovative ways to do this.

What Happens When You Can't Get an Abortion?

—By Kevin Drum

| Thu Jun. 13, 2013 7:59 AM GMT

What happens to women who want abortions but can't get them? Abortion clinics all have "gestational deadlines" and will turn away women who are further into pregnancy than their rules allow, and this gave Diane Greene Foster, a professor of obstetrics and gynecology at UC San Francisco, an idea for a study. Instead of

comparing women who have abortions to women who elect to carry their pregnancy to term, she compared a group of women who all wanted to have an abortion but didn't all get one:

When she looked at more objective measures of mental health over time — rates of depression and anxiety — she also found no correlation between having an abortion and increased symptoms....Turnaways did [] suffer from higher levels of anxiety, but six months out, there were no appreciable differences between the two groups.
Where the turnaways had more significant negative outcomes was in their physical health and economic stability....Women in the turnaway group suffered more ill effects, including higher rates of hypertension and chronic pelvic pain....Even “later abortions are significantly safer than childbirth,” she says.
....Economically, the results are even more striking. Adjusting for any previous differences between the two groups, women denied abortion were three times as likely to end up below the federal poverty line two years later. Having a child is expensive, and many mothers have trouble holding down a job while caring for an infant. Had the turnaways not had access to public assistance for women with newborns, Foster says, they would have experienced greater hardship.

The whole story is worth a read. In the long run, women who want abortions but don't get them adjust to their new lives. They aren't unhappy at becoming mothers. But there's not much question that their lives suffer, and as more and more states put more and more roadblocks in the way of abortion providers, that suffering will increase—with no mitigation from increased social services, since the red states that oppose abortion also generally don't think highly of providing much in the way of services to mothers in poverty.

Future solar cells may be made of wood

Jan 23, 2014 by Lisa Zyga

(Phys.org) —A new kind of paper that is made of wood fibers yet is 96% transparent could be a revolutionary material for next-generation solar cells. Coming from plants, the paper is inexpensive and more environmentally friendly than the plastic substrates often used in solar cells. However, its most important advantage is that it overcomes the tradeoff between optical transparency and optical haze that burdens most materials.

A team of researchers from the University of Maryland, the South China University of Technology, and the University of Nebraska-Lincoln, have published a paper on the new material in a recent issue of Nano Letters.

As the researchers explain, solar cell performance benefits when materials possess both a high optical transparency (to allow for good light transmission) and a high optical haze (to increase the scattering and therefore the absorption of the transmitted light within the material). But so far, materials with high transparency values (of about 90%) have very low optical haze values (of less than 20%).

The new wood-based paper has an ultrahigh transparency of 96% and ultrahigh optical haze of 60%, which is the highest optical haze value reported among transparent substrates.
The main reason for this good performance in both areas is that the paper has a nanoporous rather than microporous structure. Regular paper is made of wood fibers and has low optical transparency due to the microcavities that exist within the porous structure that cause light scattering. In the new paper, these micropores are eliminated in order to improve the optical transparency. To do this, the researchers used a treatment called TEMPO to weaken the hydrogen bonds between the microfibers that make up the wood fibers, which causes the wood fibers to swell up and collapse into a dense, tightly packed structure containing nanopores rather than micropores.

"The papers are made of ribbon-like materials that can stack well without microsize cavities for high transmittance, but with nanopores for high optical haze," coauthor Liangbing Hu, Assistant Professor in the Department of Materials Science and Engineering at the University of Maryland, told Phys.org.
To test the paper for solar cell applications, the researchers coated the wood fiber paper onto the surface of a silicon slab. Experiments showed that the light-harvesting device can collect light with a 10% increase in efficiency. Due to the simplicity of this laminating process, solar cells that have already been installed and are in use could benefit similarly from the additional paper layer.

Although there are other papers made of nanofibers, this paper demonstrates a much higher optical transmittance while using much less energy and time for processing. With these advantages, the highly transparent, high-haze paper could offer an inexpensive way to enhance the efficiency of solar panels, solar roofs, and solar windows.

"We would like to work with solar cell and display companies to evaluate the applications," Hu said. "We are also interested in the manufacturing of such paper."

Origins of Massive Star Explosions May Be Found

by Miriam Kramer, SPACE.com Staff Writer | March 07, 2013 02:01pm ET
http://www.space.com/20110-supernova-star-explosions-origins.html?cmpid=514639_20140125_17554014

The key to a supernova's future is in its past, scientists say.

A new study, unveiled today (March 7), may help astronomers turn back the clock on supernovas to understand how some of these massive cosmic explosions, which signal the death of stars, can occur.
By reviewing observations of 188 supernova remnants, study leader Xiaofeng Wang, an astronomer at Tsinghua University in Beijing, and his team discovered a seemingly simple way to understand what the "progenitor" star of a stellar explosion may have looked like before the white dwarf went supernova.

Wang and his team focused specifically on a kind of star explosion known as a Type 1a supernova, which astronomers use as cosmic mile-markers to measure vast distances across galaxies. Astronomers know that Type 1a supernovas can form in one of two different scenarios, both of which include a small, dying star known as a white dwarf that is about the size of Earth, but as massive as the sun.

The team analyzed the general galactic locations of the supernovas in their survey in order to understand what the area could have looked like at the time of the actual explosion. They found the stars that went supernova in more metal-rich, and possibly younger, star systems exploded more violently than supernovas born in less metal-rich areas of a galaxy.

"The typical mass of a white dwarf is not large enough to trigger an explosion; it is suggested that either merging of two white dwarfs in a binary system or continuous accretion of mass from a companion by a white dwarf is required to reach that limit," Wang said. "But the evidence from observations are not strong enough to support one scenario and refute another one." [Amazing Photos of Supernova Explosions]

These results are one more step toward solving a mystery that has beleaguered scientists researching supernovas since the 1960s.It is likely that the more explosive supernovas are caused by a white dwarf extracting mass from a companion star like the sun or a red giant, but not another white dwarf, Wang said. The less violent supernovas are probably caused by the merging of two white dwarfs.
"The basic idea is that we use these supernovae to measure distances," Ryan Foley, an astronomer at Harvard who was not involved with the study, said. "It's how we know the universe is expanding. That's great, that we measure distances with them, but it's embarrassing that we don't yet know what stellar systems produce them."

While Wang's work is consistent with other findings, by using a broad overview of survey data, the results are not as detailed as some supernova research published in recent years, added Foley.

An earlier study led by Foley used a comprehensive examination of a group of Type 1a supernovas to see that the violently exploding stars were found in gassy environments within their area of the galaxy.

"The previous way that we've found the differences is telescope time-intensive; this new way has the potential to use very little telescope time," Foley said of Wang's work. "Overall, it's a nice result, but it's one of these things that the interpretation of the results is going to take a little time to flush out."
The research was detailed online March 7 in the journal Science.

Robotics and automation, employment, and aging Baby Boomers

By Kenneth Anderson

January 23 at 10:18 am

Advances over the last couple of years in automation and robotics are drawing attention on account of their implications for the economy and especially employment. It’s not clear whether this is owed so much to an actual acceleration of technological advances as to the public noticing that the giants of information technologies – Google, for example – have decided to start placing big bets on robotics. These include self-driving cars, the “Internet of Things,” assistive care robots for the elderly and disabled, commercial drone aircraft, and many other emerging, but also potentially disruptive, automation and robotic technologies.

Tech companies likely would have done much of this anyway. There’s a convergence of interest in these technologies from many different directions. Still, the aging of the Baby Boomer population bears noting as an indirect economic driver for new machines, to make aging Baby Boomer care and maintenance more possible and affordable.

Mobile, connected, supplied, and independent within one’s own home for as long possible. Well, here you have all four: Google’s self-driving cars, Apple’s evolving iPhones as personal controller of your assistive devices, Amazon’s home delivery, and the in-home assistive robots many companies are trying to design.

The tech companies, it’s only partly an exaggeration to say, are firms whose business plans are based on old people. It’s the services they want and need as they (“we,” let me be honest) grow older, striving to maintain autonomy and independence for as long as possible. I might think (I do think) it’s unbelievably cool and not-old at all if one day I were to get a delivery by Amazon drone. But actually, after the (thrilling) first time, it’s just because I’m old, don’t really feel like leaving the house, and anyway am too infirm to do so. At least, not without a neuro-robotic “weak-limb support suit” for my legs, so I don’t lose my balance in the street and fall, and a Google car to get me to … the doctor’s office.

“Indirect” economic driver, however, because the Baby Boomers would not be paying out of their own pockets directly for many of the technologies that might be most important to them in retirement; government would wind up paying. The concomitant uncertainties, political and otherwise, that would affect what amount to “procurement” decisions within Medicare and such programs, make decisions to go into expensive and technologically thus far unproven research and development (particularly with respect to the most ambitious artificial intelligence robotics) economically uncertain, contingent propositions.

But now a familiar debate has broken out – around the employment effects that are likely to come from these new technologies. (The Economist magazine summarizes the debate and comments in this week’s edition.) On the one hand, innovative, disruptive technological change is nothing new. The result has always been short-to-medium term creative destruction, sometimes including the destruction of whole occupational categories – followed by longer term job growth enabled by the new technologies or the increased wealth they create.

In any case, over the long run, increases in the standard of living can only come through innovation and technological advance that allows greater economic output to be extracted from the same or smaller labor input. In a world of many elderly, retired Baby Boomers and historically smaller worker base bearing much of the cost of the elderly living and health care costs, that has to matter a great deal. Ben Miller and Robert D. Atkinson make the positive case for automation and robotics along these lines in a September 2013 report from the Information Technology and Innovation Foundation, Are Robots Taking Our Jobs, or Making Them?

On the other hand, maybe this time is different. That’s what MIT professors Erik Brynjolfsson and Andrew McAfee argued in their 2012 book, Race Against the Machine, and reprise in a more nuanced way in their new book, released last week, The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Machines. Maybe “brilliant machines” will replace many workers – permanently. Even without making sci-fi leaps of imagination for the capabilities of the short-to-medium term “artificial intelligence,” the emerging machines (as their designers intend them) aim to be not just “disembodied” AI computers, but instead genuine “robots,” possessed of mechanical capabilities for movement and mobility, and sensors, both of which are advancing rapidly technologies – not just AI computational abilities. Perhaps this combination – the AI robot able to enter and interact in ordinary human social spaces – does signify a break from our past experiences of innovation as (eventual) producer of net new jobs over time. Maybe significant new categories of work don’t emerge this time around – because as soon as one does, someone (or some thing) breaks it down into an algorithm, and then comes up with mechanical devices and sensors capable of executing the task – intelligently. As a Babbage column in the Economist put it several years ago, in this scenario, capital becomes labor.

What makes these machines special, then, is not just AI but, instead, AI embedded in a machine that can sense, decide, and then act, with mechanical movement and mobility, in the physical world – in the human social world. In that case, economically, changes could be unprecedented, with implications for both manual labor and even for the “knowledge workers” previously insulated from both industrial automation and global outsourcing. Unlike past technological revolutions, the result might not be whole new job categories gradually emerging (or at least ones that employ large numbers of workers).

It’s striking, however, that the argument over employment doesn’t quite directly concern the elderly. It doesn’t rationally engage aging Baby Boomers as consumers wanting these technologies and their services, or at least not Baby Boomers as both consumers and workers, with an interested foot in each camp. They’ll already be retired and so their own employment won’t be their issue. The employment issue in which, however, they will indirectly have an interest is the cost of human labor to care for them as elderly and infirm; that care is strongly labor intensive, in both unskilled and highly skilled (nursing) labor. The difficulties of machine interactions in ordinary human environments – versus, say, the highly controlled factory or assembly line floor – has meant that this sector has not so far been widely automated. But that is liable to significant change, if these technologies move forward – and if they are successful, they will have to become part of the calculation of the cost of care of the elderly, given that the technological shifts are not going to cheap, but the cost of both skilled and unskilled elder-care labor is only going to rise under current scenarios.

Which is to say, no matter where you stand on the automation-robotics-employment debate, if tech’s business plan is significantly about the growing ranks of the elderly as the target market, then to that extent, the employment debate is less important to the elderly as regards their own employment, but (at least if the technologies are successful) squarely in the cross-hairs of public policy on the costs of care for the elderly. It’s much more complicated than that, of course, and this is not to suggest that these are the only or even most significant factors. The business model for robotics is not simply about retirees; the market for self-driving cars, for example, if they come to work as hoped by Google and others, will be far wider than that; eventually it becomes about everyone. The point for now is only that the elderly form an important, though far from dominant, part of the markets for automation and robotics.

My own view is that Miller and Atkinson are mostly right about long-run job generation. The “this time is different” view seems to me overstated – as so often the case with AI, as Gary Marcus has noted. One should never rule out paradigm shifting advances, but so far as I can tell, the conceptual pathways as laid down for AI today are not going to lead – even over the long-run – to what sci-fi has already given us in imagination. Siri is not “Her” – as even Siri herself noted in a recent Tweet. For the future we can foresee, in the short-to-medium term, we’ll be more likely to have machines that (as ever) extend, but do not replace, human capabilities; in other cases, human capabilities will extend the machines. The foreseeable future, I suspect, remains the process (long underway) of tag-teaming humans and machines. Which is to say (mostly), same as it ever was.

The significant new job categories (I speculate) run toward skilled manual labor of a new kind. The “maker movement”; new US manufacturing trends toward highly automated, but still human-run and staffed factories; new high technology, but still human-controlled, energy exploitation such as fracking; complex and crucial robotic machines under the supervision of nurses whose whole new skill sets put them in a new job category we might call nursing technologist – these are the areas of work that point the way forward.

Quasi-manual labor – but highly skilled, highly value-added, and value-added because it services the machines. Or as economist Tyler Cowen put it in his 2013 Average Is Over, the next generation of workers will be defined by their relationships with the machine: You can do very well if you are able to use technology to leverage your own productivity. You can also do very well if you are able to use your human skills to leverage the productivity of the machine. If you can’t do either, though, you might gradually fall into a welfare-supported underclass – because the world of work, even apparently merely “manual” labor, is largely out of your reach.

Annals of the Presidency

On and off the road with Barack Obama.

by David Remnick January 27, 2014

Obama’s Presidency is on the clock. Hard as it has been to pass legislation, the coming year is a marker, the final interval before the fight for succession becomes politically all-consuming. Photograph by Pari Dukovic.

On the Sunday afternoon before Thanksgiving, Barack Obama sat in the office cabin of Air Force One wearing a look of heavy-lidded annoyance. The Affordable Care Act, his signature domestic achievement and, for all its limitations, the most ambitious social legislation since the Great Society, half a century ago, was in jeopardy. His approval rating was down to forty per cent—lower than George W. Bush’s in December of 2005, when Bush admitted that the decision to invade Iraq had been based on intelligence that “turned out to be wrong.” Also, Obama said thickly, “I’ve got a fat lip.”

That morning, while playing basketball at F.B.I. headquarters, Obama went up for a rebound and came down empty-handed; he got, instead, the sort of humbling reserved for middle-aged men who stubbornly refuse the transition to the elliptical machine and Gentle Healing Yoga. This had happened before. In 2010, after taking a self-described “shellacking” in the midterm elections, Obama caught an elbow in the mouth while playing ball at Fort McNair. He wound up with a dozen stitches. The culprit then was one Reynaldo Decerega, a member of the Congressional Hispanic Caucus Institute. Decerega wasn’t invited to play again, though Obama sent him a photograph inscribed “For Rey, the only guy that ever hit the President and didn’t get arrested. Barack.”

This time, the injury was slighter and no assailant was named—“I think it was the ball,” Obama said—but the President needed little assistance in divining the metaphor in this latest insult to his person. The pundits were declaring 2013 the worst year of his Presidency. The Republicans had been sniping at Obamacare since its passage, nearly four years earlier, and HealthCare.gov, a Web site that was undertested and overmatched, was a gift to them. There were other beribboned boxes under the tree: Edward Snowden’s revelations about the National Security Agency; the failure to get anything passed on gun control or immigration reform; the unseemly waffling over whether the Egyptian coup was a coup; the solidifying wisdom in Washington that the President was “disengaged,” allergic to the forensic and seductive arts of political persuasion. The congressional Republicans quashed nearly all legislation as a matter of principle and shut down the government for sixteen days, before relenting out of sheer tactical confusion and embarrassment—and yet it was the President’s miseries that dominated the year-end summations.

Obama worried his lip with his tongue and the tip of his index finger. He sighed, slumping in his chair. The night before, Iran had agreed to freeze its nuclear program for six months. A final pact, if one could be arrived at, would end the prospect of a military strike on Iran’s nuclear facilities and the hell that could follow: terror attacks, proxy battles, regional war—take your pick. An agreement could even help normalize relations between the United States and Iran for the first time since the Islamic Revolution, in 1979. Obama put the odds of a final accord at less than even, but, still, how was this not good news?

The answer had arrived with breakfast. The Saudis, the Israelis, and the Republican leadership made their opposition known on the Sunday-morning shows and through diplomatic channels. Benjamin Netanyahu, the Israeli Prime Minister, called the agreement a “historic mistake.” Even a putative ally like New York Senator Chuck Schumer could go on “Meet the Press” and, fearing no retribution from the White House, hint that he might help bollix up the deal. Obama hadn’t tuned in. “I don’t watch Sunday-morning shows,” he said. “That’s been a well-established rule.” Instead, he went out to play ball.

Usually, Obama spends Sundays with his family. Now he was headed for a three-day fund-raising trip to Seattle, San Francisco, and Los Angeles, rattling the cup in one preposterous mansion after another. The prospect was dispiriting. Obama had already run his last race, and the chances that the Democratic Party will win back the House of Representatives in the 2014 midterm elections are slight. The Democrats could, in fact, lose the Senate.

For an important trip abroad, Air Force One is crowded with advisers, military aides, Secret Service people, support staff, the press pool. This trip was smaller, and I was along for the ride, sitting in a guest cabin with a couple of aides and a staffer who was tasked with keeping watch over a dark suit bag with a tag reading “The President.”

Obama spent his flight time in the private quarters in the nose of the plane, in his office compartment, or in a conference room. At one point on the trip from Andrews Air Force Base to Seattle, I was invited up front for a conversation. Obama was sitting at his desk watching the Miami Dolphins–Carolina Panthers game. Slender as a switch, he wore a white shirt and dark slacks; a flight jacket was slung over his high-backed leather chair. As we talked, mainly about the Middle East, his eyes wandered to the game. Reports of multiple concussions and retired players with early-onset dementia had been in the news all year, and so, before I left, I asked if he didn’t feel at all ambivalent about following the sport. He didn’t.

“I would not let my son play pro football,” he conceded. “But, I mean, you wrote a lot about boxing, right? We’re sort of in the same realm.”

The Miami defense was taking on a Keystone Kops quality, and Obama, who had lost hope on a Bears contest, was starting to lose interest in the Dolphins. “At this point, there’s a little bit of caveat emptor,” he went on. “These guys, they know what they’re doing. They know what they’re buying into. It is no longer a secret. It’s sort of the feeling I have about smokers, you know?”
