Causes and Consequences of Climate Variability in the Nile Basin

The two headwaters regions of the Nile River—the western Ethiopian Highlands and the Equatorial Lakes of East Africa—lie at the intersection of powerful and competing atmospheric circulations. The regions are climatically distinct from each other and might be viewed as functionally unrelated were it not for the fact that they collectively provide virtually all of the water that flows through the main stem Nile. The Nile basin is prone to significant hydro-political tensions that are fed both by climate variability, which has significant social and economic impacts in both upstream and downstream nations, and by unilateral development of hydrological resources that has set upstream and downstream nations against each other.  In this presentation I will provide an overview of the drivers of climatic and hydrologic variability affecting the Nile basin. I will then introduce several ongoing studies that target topics of scientific uncertainty and social relevance in the Nile, including drivers of subseasonal precipitation variability, tradeoffs in water resource utilization, local climate vulnerability profiles, and the food-energy-water nexus in a changing climate.

Dr. Zaitchik is available to meet with GCC Faculty and IGC Fellows on February 1st.  Please contact Gloria Schoenholtz (schoeng@vt.edu) if you would like to schedule a time to meet him.

NASA and NOAA declare 2016 hottest on record

From The Washington Post

In a powerful testament to the warming of the planet, two leading U.S. science agencies Wednesday jointly declared 2016 the hottest year on record, surpassing the previous record set just last year — which itself had topped a record set in 2014.

Average surface temperatures in 2016, according to the National Oceanic and Atmospheric Administration, were 0.07 degrees Fahrenheit warmer than 2015 and featured eight successive months (January through August) that were individually the warmest since the agency’s records began in 1880.

The average temperature across the world’s land and ocean surfaces was 58.69 Fahrenheit, or 1.69 degrees above the 20th-century average of 57 degrees, NOAA declared. The agency also noted that the record for the global temperature has now successively been broken five times since the year 2000. The years 2005 and 2010 were also record warm years, according to the agency’s data set.

NASA concurred with NOAA, also declaring 2016 the warmest year on record in its own data set that tracks the temperatures at the surface of the planet’s land and oceans, and expressing “greater than 95 percent certainty” in that conclusion. (In contrast, NOAA gave a 62 percent confidence in the broken record.)

NASA found a bigger leap upward of temperatures in 2016, measuring the year as .22 degrees Fahrenheit higher than the prior record year of 2015. The agency also noted that since the year 2001, the planet has seen “16 of the 17 warmest years on record.”

Last year “is remarkably the third record year in a row in this series,” said Gavin Schmidt, who directs NASA’s Goddard Institute of Space Studies, in a statement. “We don’t expect record years every year, but the ongoing long-term warming trend is clear.”

The record comes two days before Donald Trump, who has tweeted that global warming is a “hoax,” assumes the presidency and, with it, control over the two science agencies that announced these records. It is also the same day that Scott Pruitt, Trump’s controversial nominee for the Environmental Protection Agency, is appearing before the Senate in an often-tense confirmation hearing in which he has been questioned about climate change. Pruitt has previously written that the “debate” over climate change is “far from settled.”

Trump’s other nominees, such as State Department nominee Rex Tillerson and Interior Department nominee Ryan Zinke, have been less dismissive of climate change in their confirmation hearings, acknowledging at least some human contribution to the phenomenon but also raising questions either about the extentto which it is human-caused or about our capacity to predict the consequences. On Wednesday, Pruitt acknowledged that climate change is not a “hoax” and said that “the climate is changing, and human activity contributes to that in some manner.”

Scientists have been far less guarded. “2016 is a wake-up call in many ways,” Jonathan Overpeck, a climate scientist at the University of Arizona, said of the year’s temperatures. “Climate change is real, it is caused by humans, and it is serious.”

NASA and NOAA produce slightly different records using somewhat different methodologies, but have now concurred on identifying 2014, 2015 and 2016 as, successively, the three warmest years in their records. There was a noticeable difference this year, however, in how much two agencies judged 2016 to have surpassed 2015. NASA was more bullish — a difference that Schmidt, in a press call Wednesday, attributed to different ways of measuring the Arctic.

“The warming in the Arctic has really been exceptional, and what you decide to do when you’re interpolating across the Arctic makes a difference,” Schmidt said.

Association for Computing Machinery names Ed Fox a 2017 Fellow

From VT News

Edward Fox was an undergraduate on the cusp of launching his career at the Massachusetts Institute of Technology when he joined the Association for Computing Machinery.

Fifty years later, Fox has been named a 2017 ACM Fellow for his contributions to information retrieval and digital libraries.

“To be selected as a Fellow is to join our most renowned member grade and an elite group that represents less than 1 percent of ACM’s overall membership,” explained association President Vicki L. Hanson. “The Fellows program allows us to shine a light on landmark contributions to computing, as well as the men and women whose hard work, dedication, and inspiration are responsible for groundbreaking work that improves our lives in so many ways.”

Fox’s long history of service at ACM reflects his dedication to the organization. Presently he is program chair for the 2018 ACM/IEEE Joint Conference on Digital Libraries — also serving as general chair in 2001 and as a member of the steering committee since 2003. Fox was editor for information retrieval and digital libraries in the ACM Books series; founder and co-editor-in-chief for the ACM Journal of Educational Resources in Computing; and a member of the editorial board for ACM Transactions on Information Systems.

Other positions Fox has held at ACM include: vice chair and then chair of the Special Interest Group on Information Retrieval from 1987 to 1995; founder and chairman of the steering committee for the ACM Multimedia conferences from 1992 to 1994; and founder and chairman of the steering committee for the ACM Digital Libraries series of conferences from 1995 to 1998.  He received ACM Recognition of Service Awards in 1991, 1995, 1996, 1999, and 2012.

Currently Fox holds several positions at Virginia Tech as a professor in the Department of Computer Science in the College of Engineering. By courtesy he is faculty in the Bradley Department of Electrical and Computer Engineering. Fox is also a faculty member in the Discovery Analytics Center; the Center for Human-Computer Interaction; the Global Change Center; and the VT Center for Autism Research, as well as director of the Digital Library Research Laboratory.

Fox joined Virginia Tech in 1983. He received the university’s XCaliber Award in 2016 in recognition for his work in developing and enhancing two computer science courses, Computational Linguistics and Informational Retrieval. Both focus on student engagement and mastery of the material and are designed to provide students with skills that are in great demand in the workplace.

His work with information retrieval and librarianship can also be seen outside the classroom in Virginia Tech’s branding. In 1984 Fox registered several different domain names, in addition to the current one, through a National Science Foundation-funded project called CSnet. By 1987, “vt.edu” was the officially registered domain used by the campus.

Fox also led Virginia Tech in joining the Cloudera Academic Partnership in 2015, providing the university with educational resources and support provided by this leading company in the area.

Earlier in 2017, he was named an IEEE Fellow. He has been a senior IEEE member since 2004.

Fox’s research interests include all aspects of Information, including theory, algorithms, systems, experimental studies, web, social networks, natural language processing, and user interaction/ usability. His related international service include founder and executive director of the Networked Digital Library of Theses and Dissertations.

He has been a principal or co-principal investigator on 124 research grants/contracts, taught more than 82 tutorials, and has given 66 keynote/distinguished/international invited talks. He has authored or coauthored 18 books, 129 journal/magazine articles, 49 books chapters, 219 refereed conference/workshop papers, 74 posters, and more than 160 other publications/reports. He has given more than 330 additional talks.

Fox received his bachelor’s degree in computer science from the Massachusetts Institute of Technology and an M.S. and  Ph.D. in computer science from Cornell University.

As an undergraduate, Fox’s mentor was J.C.R. Licklider, sometimes called “the grandfather of the Internet” for having administered the first grants for work on the Internet while working at DARPA. Another computer science pioneer, Gerard A. “Gerry” Salton, often referenced as “the father of information retrieval,” was Fox’s advisor and mentor at Cornell. They published a number of papers together.

“I am so honored to be selected as an ACM Fellow,” said Fox. “I am very grateful for the help from all of my mentors over the years, especially Drs. Licklider and Salton, and for all my collaborators, colleagues, and students; Virginia Tech; the computer science department; those involved in electronic theses/dissertations; sponsors; the information retrieval and digital library communities; and my wonderful family. They have all been instrumental in my success.”

The 54 Fellows chosen this year hail from universities, companies, and research centers in Canada, China, Denmark, Germany, Hong Kong, Switzerland, the United Kingdom, and the United States. They will be honored at an awards banquet in San Francisco in June.

Communicating Science: GRAD 5144 offered spring semester

[vc_row][vc_column][vc_column_text]January 10, 2017

Two sections of GRAD 5144, Communicating Science, are being offered this spring (2017), and there are a few seats remaining. To accommodate the cycle of work in grad students’ lives at the beginning and end of the semester, the course is compressed into ten sessions, beginning the week of January 30 and wrapping up the week of April 17. Class will not meet the week preceding spring break (or, of course, spring break week).

This 2-credit participatory course uses theatre improv games and writing exercises to help students become more comfortable with and effective at communicating their research to non-scientist audiences. Participants also find that it helps them with lab meeting presentations, talks at conferences, and communication in committee meetings and collaborative research. GRAD 5144 is intended to promote understanding of science by training the next generation of scientists, engineers, and health professionals to communicate more effectively about their work in a variety of contexts.

Virginia Tech students have had the following to say about their experience:

“The class has been great fun, the high spot of every week and a real learning opportunity for me. I am extremely impressed at the progress we have all made.”

“This course is the best I have taken at Virginia Tech. It has helped me grow as a researcher and as a person.”

“I will take away numerous lifelong lessons from this class on my continuing quest to be an effective scientific communicator.”

“I will remember this course and what I have learned for the rest of my life. It has completely changed the way I feel when sharing information about my work.”

“Personal and professional development is at the core of this remarkable class.”

“I won first place in the poster competition and got $500! I could not have done it without this class.”

Water is the latest battleground in Syria

From CNN

Nour, a housewife in Damascus, says the latest joke in the Syrian capital is also a prayer of sorts: “May the gold you hold become water.”

It is a half-hearted attempt to make light of a water crisis that is impacting millions in Damascus, a city that has been relatively sheltered from the violence raging elsewhere in the country.

Nour said that her family just got water on Tuesday morning, after four days without access. Her family quickly lined up to use the shower and she switched on the washing machine. Now, when she hears the sound of the water motor running, she says it is “like a wedding.”

“When the water comes, it’s the same joy as a mom having a boy after 10 daughters,” Nour said. She did not feel comfortable sharing her last name with CNN.

Some four million people in Damascus have suffered from acute water shortages for more than a week after springs outside the Syrian capital were targeted, the UN’s Office for the Coordination of Humanitarian Affairs (OCHA) said in a statement on December 29.

Water from the Wadi Barada and Ain al-Fija springs, which serve 70 percent of the population in and around Damascus, was cut after infrastructure was damaged in fierce clashes. OCHA described the damages as “deliberate,” without saying who was responsible.

The Syrian government and rebel forces are trading blame for the water shortages.

Rebels claim the government destroyed the water pumping station in the Wadi Barada valley, one of the last remaining rebel-held pockets of Damascus.

The Syrian army and its allies are pushing to recapture Wadi Barada in spite of a nationwide ceasefire. The regime claims it is going after rebel groups who were excluded from the truce, like former al Qaeda affiliate Fateh al-Sham, which it says is operating in the area (although local groups deny this).

 

The Syrian regime has accused rebels of contaminating the springs with diesel, forcing the Damascus water authority to cut the supplies. CNN could not independently verify these claims.

 

A group of pro-opposition groups and civil society organizations in Wadi Barada, including the Local Council and the Syrian Civil Defense, released a statement on Monday calling for the International Committee of the Red Cross and the United Nations to assess damages at the Ain al-Fija spring, situated northwest of the capital in a mountainous area near the border with Lebanon.

 

“(We express) our willingness and readiness to accompany and assist teams heading to al-Fija spring to accelerate resupplying fresh water to our people in Damascus city,” the statement read. “This facilitation needs to be accompanied with activating the ceasefire in Wadi Barada region and halting the aggression conducted by the Syrian government forces backed by Hezbollah militias.”

 

The Syrian government denies any involvement in the destruction of the springs. State-run Syrian Arab News Agency (SANA) reported on December 27 that the springs in Wadi Barada “came out of service as a result of terrorist acts.”

Fighting the climate crisis with $150 homes in Africa

From CNN

Deforestation and climate change have triggered a housing crisis in West Africa

Millions of households in the Sahel region of West Africa live under a growing threat. Deforestation and climate change have decimated the available supply of wood that is used for traditional roof construction, forcing many to use imported sheet metal. This is both prohibitively expensive and unsuited to the climate, entrenching poverty and making homes that boil in summer and freeze in winter.

One creative enterprise is reaching back over 3,000 years for a solution, borrowing an architectural technique from the ancient Nubian civilization of latter-day Sudan to offer superior homes at minimal cost. The NGO La Voute Nubienne (Nubian Vault) is training an army of masons to build homes from the earth, and the ancient innovation is having a profound impact.

The Nubian technique uses bricks and mortar produced from local earth, laid over a foundation of rocks. A home can be produced in 15 days, and the method is versatile enough to produce a range of buildings from mosques to farmhouses.

La Voute Nubienne is working in five West African countries; Burkina Faso, Mali, Senegal, Benin and Ghana, where around 20,000 people now live in the Nubian homes.

“We have proved our concept is viable and works for the population,” says Thomas Granier, a French builder who co-founded the NGO with Burkinabe partner Séri Youlou. “There are half a billion Africans living under corrugated iron roofing and our target is to provide a strong alternative.”

The earth homes offer more than expediency, as they are well adapted to the local climate. “Nubian Vault buildings provide excellent thermal insulation, making the buildings cool during the day and warm during the night,” says Nick Nuttall, spokesperson for the United Nations Framework Convention on Climate Change (UNFCCC).

La Voute Nubienne believe that long term success depends on building a sustainable market, as expressed in their motto: “A roof, a skill, a market.” The NGO has trained over 500 masons, according to Granier. This new workforce can respond to increasing demand, as well as training a new generation to sustain the practice.

One-third of the new construction market is now fully autonomous, and the proportion is rising.

“When we have deployed enough capacity this won’t belong to us, it will belong to the community,” says Granier. “The target is push this alternative until we don’t have to and it pushes itself.”

The market model does not make the homes unaffordable. Granier estimates the cost of a basic building at $150, although in many cases the owner will supply some of their own labor, or barter goods for part of the mason’s fee.

But despite the informal nature of the industry it is making significant contributions to the local economies, valued at over $2 million by the NGO, and this figure is set to rise.
