Water security is a multi-dimensional strategy: Ex-CWC chief
Water security is a multi-dimensional strategy and no unique solution or panacea exist for ensuring the water security of the country and there is imminent need to change consumption and management, said former chairman of Central Water Commission and former Director General of National Water Development Agency Ashwinkumar Balvantray Pandya here on Saturday.
Visakhapatnam: Water security is a multi-dimensional strategy and no unique solution or panacea exist for ensuring the water security of the country and there is imminent need to change consumption and management, said former chairman of Central Water Commission and former Director General of National Water Development Agency Ashwinkumar Balvantray Pandya here on Saturday.
Delivering Dr KL Rao Endowment Lecture on ‘Water, energy and food security nexus’ at Dr KL Rao centenary celebrations organised by GITAM University Civil Engineering Department, he said that it was not possible to sustain the water security with one time solutions as there are many factors like climate change and global economic situations continuously impacting the availability and usage patterns.
The solutions once applied will have to be continuously monitored and tweaked for ensuring that the regime once established keeps on delivering results for generations to come, he added. He said that irrigation sector is the major water consumer and one of the most sought-after strategy is improving the irrigation efficiency and saving water.
The present level of overall efficiency is about 35 per cent. However, the improvement of efficiency will require multiple interventions in storage, conveyance and application methodologies practiced.He informed that the country has built up storages worth about 250 billion cubic metres (BCM) and 50 BCM capacity is under construction or consideration.
He said that the National Commission on Integrated Development of Water Resources estimated that an aggregate storage capacity of 450 BCM is needed for efficiently managing the utilisable surface water resources of 690 BCM. He pointed out that sustained diplomatic and economic efforts are the requirement of the day when our in-country sources are coming under stress from operation and implementation angles.
