BBISS Researchers Tour Eco-Cities in China


Profs. Crittenden and Brown tour Tianjin Eco-City.
It would be no surprise to anyone to hear that China is well into a building boom.  The nation is very rapidly urbanizing due to its expanding manufacturing sector.  Large cities are being constructed from scratch where there once was open rural land.  It might surprise some that many of these will be eco-cities, designed and constructed with sustainable design features, materials, and infrastructure systems.  The speed and scale of these projects affords a rich opportunity for research and innovation towards a better understanding of what constitutes an “eco-city” in the real world.

Toward that end, a delegation from Georgia Tech recently participated in “The China-US Workshop on Environmental Protection and Urban Sustainable Development” in Tianjin.  It was co-organized by the ChineseNational Natural Science Foundation and the U.S. NationalScience Foundation and co-hosted by TianjinUniversity and Georgia Institute of Technology.  The U.S. delegation of investigators are part of an NSF funded project from the Emerging Frontiers in Research and Innovation - Resilient and Sustainable Infrastructures (EFRI-RESIN) program called, “Sustainable Infrastructures for Energy and Water Supply (SINEWS).”   The Chinese delegation is affiliated with the ResearchCenter for Eco-Environmental Sciences (RCEES) at Tianjin University.

The workshop focused on the current status of the urban environment, its challenges, its future, and sustainable development strategies.  There were three technical areas of focus for this networking workshop:
  •  water/energy nexus
  • land use
  • ecosystem services
The goal of the workshop was to establish in-depth discussions and garner lessons from an international community of scholars about some of the key issues impacting the urban environment.  Consideration was also given to how the delegations could provide support for each other’s research and how government decision making could play a role in advancing the state of the art.

This workshop will not only help to advance the sustainability of the eco-cities in China, but also offers examples of innovations that are applicable to other cities.  Serving as a backdrop to this event, participants toured the new eco-city development in the Bei Hi district which is south of Tianjin.  This eco-city is a joint effort between the governments of China and Singapore and will have 350,000 residents.

St. Patrick’s Day to Earth Day : a Month of Green

One of the most common ways to get into the spirit of St. Patrick’s Day is to wear green clothing, in our case, socks. While expressing one’s green inclinations outwardly with colorful attire should never be discouraged, opportunities abound at Georgia Tech to act on, and internalize that spirit of green. So, perhaps St. Patty’s Day is best seen as a warm-up to a whole month of green themed events culminating with Earth Day. Take a look at all that’s happening at Georgia Tech over the next month.
  • Every Thursday (Except March 22nd) in Tech Walkway 11 AM – 2 PM - Georgia Tech Farmers Market.
  • Now until March 30th - Donate items for the Earth Day Office Supply Exchange.

China's Carbon Export

November 2011

Among countries, China recently has become the largest emitter of carbon dioxide. This milestone was reached at an astonishingly rapid pace. The drivers of China’s emissions explosion are obvious, but the policies for dealing with it are more complicated than one might assume. International manufacturing and trade has turned China into the world’s factory. This raises the question, “How much of China’s carbon emissions are exported in the form of the manufactured products to be sold in developed countries?” Researchers at the Brook Byers Institute for Sustainable Systems (BBISS) at Georgia Tech, the University of Michigan, and Tsinghua University recently published a study that aims to answer this question. One of their findings is that in 2008, 48% of China's carbon emissions were in the form of exported goods.

Take a look at the abstract for more details: ScienceDirect

A Letter to Entering Freshmen at Georgia Tech, Class of 2015

For the last 150 years, the United States has been a global leader in technological innovations of all kinds that have increased prosperity, improved health, and provided positive opportunities for all humans throughout the world. For 125 of those years, Georgia Tech graduates have played a significant role in that long run of human progress, and come August, you will join the ranks of engineers, scientists, architects, managers, planners, industrialists, and entrepreneurs that make it all happen. You will come to campus with the expectation that a Georgia Tech education will help you to understand, engage, and prosper in an ever increasingly complex, competitive, and interconnected world. You expect that your undergraduate training will prepare you for the challenges you will meet throughout your professional and personal lives. Challenges for students entering the college stream in the last decade were terrorism, the rise and fall of the technology market, and worldwide financial collapse. Three decades ago, students were challenged by the Cold War, a new and unknown disease called AIDS, and the stunning rise of Japanese manufacturing prowess. Here in the second decade of the third millennium, your challenges are no less daunting (and perhaps more so):

     Population growth is an ongoing challenge as we prepare to provide 7, 8, and 9 billion people with food, shelter, security, mobility, employment, healthcare, governance, child care, elder care, and more. This must occur amid greater competition for increasingly scarce material and energy resources, and diminishing capacities to assimilate wastes.

     For the first time in human history, more people now reside in urban areas than in rural areas. This trend of urbanization will continue. In developing countries, new infrastructure will need to be built to provide water, housing, transportation, sanitation, communications, and industrial (including energy) production and distribution.  In developed countries, the aging built environment will need to be rebuilt or replaced, and natural systems restored in order for those countries to remain functional and competitive.

     Human caused global climate change now threatens to disrupt the order of nature on which we are dependent. This includes disruptions to the biosphere, hydrosphere, cryosphere, and atmosphere. Dramatic changes in how energy is produced and used are needed to mitigate further impacts, and for impacts already likely to occur, measures to transition terrestrial and aquatic ecosystems to new climate regimes are required (e.g. farms, forests, and fisheries). Additionally, plans must be created and implemented to manage new threats caused by climate change such as increased storm frequencies and intensities, human and other species migrations and extirpations, and transportation and distribution service interruptions.

     As international barriers to communication, transportation, finance, and labor continue to fall, globalization will continue to grow. With it, so too will grow new markets and business opportunities, cultural exchanges, and the flow of goods, people, information, and ideas. This in turn will require new internationally binding rules, laws, and oversight, coordinated diplomatic efforts, and wisdom in navigating foreign lands and cultures born of experience and empathy.

For its part, Georgia Tech must be forever looking across and over the horizon, and constantly revising and adapting its curriculum to meet each new incoming class’ existing and emergent needs and desires. Like every generation prior, the challenges and opportunities that are surfacing are unprecedented in scope and speed and require an altogether new approach to education. So what is it that Georgia Tech is doing, and what is it that you must take advantage of during your time here that will help you meet these challenges?

     At a first level, Georgia Tech is removing barriers to interdisciplinary studies and research. By allowing students to more freely craft a degree curriculum, the Institute is able to respond quickly to the demand for graduates in the cross-over and hybrid careers that are the foundation of the flat world in which proficiency in a single discipline is no longer a guarantor of success. Industrial ecology is a product of the life sciences and engineering in which waste from one process is feedstock to another, leading to lower environmental impacts and higher revenues. Biomimicry "is a new discipline that studies nature’s best ideas and then imitates these designs and processes to solve human problems.”

     In a nod to globalization, Georgia Tech is providing more international experiences. In both sending students abroad and receiving them in-kind, the Institute is expanding the worldviews of students and enabling their ability to see and solve problems from many different perspectives. And through these experiences, students also see that solutions that simply transfer problems to others are unjust. Especially obvious are the environmental kind as these are often the most manifest and tangible.

     Recognizing that even the universities are limited in their ability to foresee the needs and opportunities in the future and prepare students accordingly, schools are putting more emphasis on teaching students how to teach themselves. This includes fostering more undergraduate research and entrepreneurship. In turn, graduates are less bound by the status quo and more able to develop new ideas, technologies, and business ventures that are more effective, profitable, and efficient.

     Finally, at the highest level, the Brook Byers Institute for Sustainable Systems is helping Georgia Tech recast its education, research, and service missions around the core concept of sustainability. In so doing, it seeks to align the mission of Georgia Tech with the mission of the next generation of students to create an anthrosphere that exists within the means of nature. That is, to use resources that nature can provide and only generate wastes that nature can assimilate. In adopting this mission, Georgia Tech and its graduates will help provide the developing world opportunities to lead useful and productive lives, and enable the U. S. A. to become the global leader in developing more sustainable technologies, achieve energy self-sufficiency, and become the most generous country in the world again by providing medicines, technology transfer, and aid to people everywhere.

Class of 2015, welcome to Georgia Tech. Go Jackets!
