Reading the title of the paper, I imagined an interesting comparison between cities, both on water-fronts but quite different as to ecological awareness of the population (Vancouver, with high awareness; Buenos Aires, with low awareness).
Reading the paper I noticed, with surprise, great similarities between both cities on the matter, while the abovementioned differences are so wide. It would be interesting to find out about this assymetry. My intuition leads me to infer that our contemporary universal life-style and capitalistic system has much to do with it.
About the fruitful insight of possible changes on the future of Buenos Aires sewage management and of the reutilization of resources within the excrements of city inhabitants because of energy scarcity, I see an interesting scenario for change. With reference to this, I want to point out to what happened at the end of year 2013. During huge and long black-outs in Buenos Aires City thousands of old and handicapped people living in high buildings were trapped up in their apartment without elevator, electricity, water and sanitary facilities. Against city mayor response (“we’ll buy and install hundreds of gasoline-run electrical generators for each of those buildings”) originated a proposal from people´s assemblies to start a Green Plan involving one million new trees for the city streets, considering -besides other benefits- that the cooling effect of one tree is equivalent to one medium home air conditioner; and as for water pumping, photovoltaic pumps would be of great interest.
