Webinar Today / The Ganges Water Machine
In the Ganges, 80% of the monsoon-driven flow is concentrated during 4 months (July-October), while flow during the dry season is barely sufficient for irrigation needs.
In 1975, hydrologists R. Revelle and V.Lakshmi Narayana proposed that a portion of the monsoon waters be stored underground for irrigational use during the dry season. The approach was to include:
They called it the ‘Ganges Water Machine.’
The proposition was hydrologically sound. However, over the years it has been adopted only in bits and pieces. Nevertheless, even recent studies (such as the 2012 World Bank Assessment of the Ganges Basin Development) still highlight its great potential for flood protection and irrigation benefits in the Ganges basin. (Read more in the blog ‘… a sexy title or a concept of global relevance?’)
So what has kept governments and engineers from adopting the machine? Is it still a plan worth pursuing?
This is one of the topics Dr Mohammad Shamsudduha from University College London will discuss in a free, open webinar today (1100 GMT, click here for local timings). Titled ‘Groundwater and Climate Adaptation in the Bengal Basin,’ the webinar will address a range of solutions with potential to restock aquifers in the region that houses over 230 million people.
