CSTEP Chair Anu Ramaswami Quoted in NY Times on the Difficulties of Ranking "Clean" Cities

Dr. Anu Ramaswami, Professor and Charles M. Denny, Jr., Chair of the STEP area, lent her expertise to a NY Times article, "The Cleanest Cities? It's Not So Simple," part of an ongoing series in Energy & Environment, Special Report: Energy for Tomorrow. 



"Evaluations of energy intensity often adjust for differences in economic development, industrial bases, climates, population density and other factors to make a more equal comparison.
The drawback then is that “every city ends up being the same,” said Christopher Kennedy, a professor of civil engineering at the University of Toronto and the lead author on the megacities study.
Another way to compare cities is one economic or social segment at a time, such as transportation or industry, said Anu Ramaswami, . . ." Read the full article here.
Dr. Ramaswami's work with the National Science Foundation-supported Sustainability Research Network highlights integrated urban infrastructure solutions for healthy, livable, and sustainable cities. More at www.sustainablehealthycities.org.

Andrew Fang on The Food-Energy-Water (FEW) Nexus - Implications for Urban Sustainability

STEP PhD Candidate Andrew Fang presented Monday on The Food-Energy-Water (FEW) Nexus as part of the bi-weekly STEP-FAR (Feedback and Research) Seminar series.


The Food-Energy-Water (FEW) Nexus - Implications for Urban Sustainability

Cities in China, India and the US face continued issues of water scarcity which will likely be exacerbated by the effects of climate change. Many of these cities also rely on far-reaching supply chains to procure enough food, energy, and water to support urban activity.


While cities are aware of their water demands, the water resources they rely on generally come from non-local sources, particularly in the western US and India. Additionally, up to 47% of water withdrawn in the US is used by the electricity sector, while 70% of global freshwater consumption is attributed to the agricultural production. Therefore, cities must consider the needs of these sectors in order to develop effective strategies to manage the water resources they rely on. In particular, I focus on the cases of Delhi and California to examine the implications of the FEW nexus on both the regional supply chains and urban water demands in order to determine what cities can do to secure their future water supplies.
