Typology of GDASEs

Why?

Build management strategies that are type-specific

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?)

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

Pastoral systems Ecosystem ‘preserves’

Interventions (by aquifer type)

Pull back (or increase supplies – eg

MAR, water transfers)

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 -
