Typology of GDASEs
Why?
Build management strategies that are type-specific
![Page 2: Typology of GDASEs Why? Build management strategies that are type-specific](https://reader036.fdocuments.net/reader036/viewer/2022072013/56812c80550346895d9130ae/html5/thumbnails/2.jpg)
Developing a typology…
• Setting the right objectives when combining groundwater development & management strategies in conjunction with ESSs
• Scenario building as a consequence of the typology of situations and interventions
• Opportunities in different scenarios could drive the strategies and interventions at different scales

A time-line (or loop?)
Current (situations)
Interventions
(what is vs what should)
Future (scenarios)
Build strategies that are type-specific

Typology of contexts
• Macroeconomic ; legal /institutional
Typology of local situations
• Physical – resource and ecosystem
• Human use (agro-ecology and degree of use)
• Social and cultural capital

Situations
Punjab, Haryana, parts of Peninsular India
Central India; parts of the Indo-Gangetic basin; parts of the middle Himalayan
region including the emerging agrarian regions of Himalayan Highlands
?Areas with heavy mining but relatively low agrarian footprints – parts of Chhatisgarh and Odisha as well as parts of Goa…??
Himalayan region, Northeastern India, parts of Eastern India, especially the
Northern part of Eastern Ghats and the Southern part of Western Ghats

Typology of agro-eco systems
Industrial agriculture; arid agrarian systems
Sustainable agricultural systems
Pastoral systems Ecosystem ‘preserves’

Interventions (by aquifer type)
Pull back (or increase supplies – eg
MAR, water transfers)
Opportunistic – comprehensive set of
interventions
UnconventionalRegulated / strategic
development

Aquifer types• Alluvial• Sedimentary
• (soft and hard)
• Volcanic• Crystalline• Lateritic
Structure / topography dominated
(eg mountain)
• Highly dynamic
• Dynamic
• Static
Confined vs unconfined

Contexts
• Description rather than typology?
• eg Australia – strong institutional and legal setting; tradable water rights; implementation through strong state agencies
• South Africa – strong legal framework, explicit water rights for ecosystems; implementation through weaker local government
• Sri Lanka -
