7th Asian G-WADI Meeting cum Workshop
at CSIR-National Geophysical Research Institute, Hyderabad, India
with the support of National Institute of Hydrology & IHP Indian National Committee (Ministry of Water Resources, RD-GR, Govt. of India), Roorkee, India
November 26-30, 2017, Hyderabad, India
ACCELERATED MARCHING OF GWADI IN 2ND DECADE:
Safeguarding Water Resources in Semi-arid regions through Integrated Management
G-WADI, a global network on Water And Development Information for arid lands (www.gwadi.org) is a and flagship program of UNESCO. Under this program, a number of regional network have been established and Asian G-WADI (http://asian-gwadi.westgis.ac.cn) was formed during 2004 with its first secretariat in India at National Institute of Hydrology, Roorkee with initially 3 countries, India, Iran and China. As far as water is concerned, arid and semi-arid countries face the most challenges in managing this resource. Thus such network was created to learn from each other’s experiences and adopt best practices through this network for a successful water management. Annexure 1 provides detailed objectives and Annexure 2 its further details on the member countries and pilot basins etc. At present 13 countries have joined the network of Asian GWADI.
Under this program, a few representative areas have been selected for detailed study so that findings could be shared, discussed, improved and implemented in the best possible way. A series of meetings are therefore, held in the member countries to discuss the progress in the study as well as advances in the field of water sciences. The 1st meeting of Asian G-WADI was held in Roorkee, India during 2004 and since then 5 subsequent meetings were held in China and Iran where annual or bi-annual progress have been discussed.
We have recently celebrated very well the progress of the network in more than a decade in Beijing, China organized by the CAREERI and CAS, Peoples Republic of China. Now we have to march faster and up-scale most of the knowledge gained in different environments. The Asian GWADI has also grown bigger and have the advantage of inclusion of the study areas from a variety of agro-climatic and geological regions. Thus next and 7th meeting is proposed in India with following objectives.
- GWADI has established very well with the working knowledge on the applications of Remote Sensing, Rainfall-runoff relations as well as surface water dynamics including Climate Change. However, the knowledge on the groundwater system has been lacking behind although, groundwater works very well as a risk saver if we adopt integrated water resources management. At the same time a large number of uncertainties are associated with groundwater due to inherent variability.
- We have overcome this uncertainty to a greater extent by obtaining a 3D continuous picture of the subsurface in the form of Aquifer Mapping using airborne geophysical investigations.
- However, rainfall that is source of water has been greatly affected by the Climate Variability and has further added the uncertainties. The impact on groundwater is very well established and observed. Groundwater is most affected due to Climate Change in the form of erratic rainfall, increase in temperature, sea level rise etc.
Now under the changing climate scenarios and with an enhanced knowledge of sub-surface, the estimates of all components of groundwater cycle need to be revisited and bring out an improved or modified methodologies for the same. This is urgently required as this will greatly affect the planning as well as sustainable management.
This is why a workshop is proposed in the form of next Asian GWADI meeting at the CSIR-National Geophysical Research Institute, Hyderabad, India to learn from the working experience in different agro-climatological regions and bring out a revised document embedded with improved and stochastic estimates under Climate Changed scenarios.
UN-SDG may be successful only if we reduce the uncertainty of the estimates of the groundwater fluxes that have been changed considerably due to Climate variability.
The expected Number of participants is 45 (with 19 from abroad from the member countries, experts and UNESCO officials).
The outcome of this meeting will bring out a document that includes the guidelines to improve and test the methodologies to estimate various fluxes of the groundwater system for an Integrated Water Resources Management and test them in well-studied watersheds to bring out the finalized recommendations by a working group.
