The cross-over came from the UN Conference on Environment and

Development (UNCED) (Rio Conference) and the parallel Dublin Conference. The Dublin

Principles call for both the commodification and the democratization of water.

The global discourse on

sustainable development is being driven from

this quadrant.

But many developing countries needs are

still located in this quadrant

The big challenge to understanding the groundwater issue is thus to

understand the IWRM discourse and to critically examine the concepts relating to governance

and oversight as they apply to specific socio-cultural, economic

and historic contexts. In short it is about understanding 2 nd Order

Resource Scarcity.

This is about rule making, rule application and rule

adjudication.

This is about society, economy and ecology, i.e

the sustainable development discourse.

This is about legitimacy of the government processes.

This is about a balance and integration between the natural

and the social sciences.

This is about science informing and supporting the policy-making process.

This is about science in the service of society.

2 nd Order Resources keep it

all in balance and in synch.
