Recent news about water crises has again got me thinking about the issue of reaching the maximum levels of extraction of natural resources and then every effort put in results into getting less and less of it.
This is not only true for water or oil, but also for renewable resources like wood. In my field experiences of visiting and staying in villages I often encountered cases of how the depletion of forest has led to increased drudgery over women. Their road miles (these roads are different) for fetching wood to be able to cook has constantly been going up. Once a women explained how the time it takes her to fetch wood is twice as much while the quality of wood is not the same.
Similar would be the case for our efforts in fetching ground water. In fact the increasing depths of borewells in cities is an example of how we are putting in more effort to fetch water which is inferior in quality (often higher TDS is recorded in deep borewell water). The more deeper we go it costs more (electricity for pumping and higher horse power motors). As the ground water crises deepens, at some point in time the costs of water could become so high that we may end up buying it from rationing shops. Hopefully water riots could still be avoided.
Crude oil is no different. My introduction to the world of sustainability or rather un-sustainability was through my research on oil as a commodity in the stock markets. My own modeling projections revealed that the rate at which we are able to extract oil would peak soon and then the supply would be unable to keep up with the demand. This means that the demand would have to adjust. Either by choice or force. The case is pretty similar to water. The demand for water could automatically get managed if we have to purchase it through open markets or if it gets rationed.
So joining the three dots that I mention above, wood, water and oil, today I again think of the issue of peaking of resources and how they are due to transform our lives. Richard Heinberg wrote a book on this called Peak Everything, 11 years ago. I had also read on the issue of peak gold where the underground extraction of gold peaks in a similar fashion like oil and water. The only difference is gold is a non consumable item and hence would still be available in the markets. But oil and wood are being burnt and converted into CO2 while ground water is extracted, evaporated and converted into waste through industrial, agricultural and household consumption.
While it can be argued that freshwater is renewable and thus if we reduce our consumption then we could have more of it. But one must remember that the ground water that we extract is a resource stock build up over centuries which we have exploited in great hurry. In order for that stock to build up again it could take a long long time. Hence, for our day to day purposes ground water is somewhat non renewable.
During my first encounters with the resource depletion issues I thought re-localisation would be a strategy to defy all odds. One relocates to a resource abundant small geography and maintains it through a community driven process. It has been close to 10 years and in reality I have only gone farther away from the idea.
But these recent news of water crises has got me thinking again.
