2Avg national water footprint per capita, 1997 -
2001
3 Water footprint of a product
? the volume of fresh water used to produce the
product, summed over the various steps of the
production chain. ? when and where the water
was used a water footprint includes a temporal
and spatial dimension. ? type of water
use green, blue, grey water footprint.
4 Water footprint of a product
- Green water footprint
- ? volume of rainwater evaporated.
- Blue water footprint
- ? volume of surface or groundwater evaporated.
- Grey water footprint
- ? volume of polluted water.
5 Components of a water footprint
Direct water footprint
Indirect water footprint

water)

water)

10Water footprint of EUs cotton consumption (grey
water)

consumption in one place and impacts on water
systems elsewhere

12This is a global average and aggregate number.
Policy decisions should be taken on the basis
of 1. Actual water footprint of certain coffee
at the precise production location. 2. Ratio
green/blue/grey water footprint. 3. Local impacts
of the water footprint based on local
vulnerability and scarcity.

17Water footprint of biofuels from different crops
litre/litre
Gerbens-Leenes, Hoekstra Van der Meer, 2009
18 Water footprint of a nation
- ? total amount of water that is used to produce
the goods and services consumed by the
inhabitants of the nation. - ? two components
- internal water footprint inside the country.
- external water footprint in other countries.

22Water footprint Life cycle assessment
- LCA
- measuring overall environmental impact
- no spatial dimension
- weighing water volumes based on impacts
- LCA offers basis for comparing products with
respect to overall environmental impact
- Water footprint
- measuring freshwater appropriation
- multi-dimensional (type of water use, location,
timing) - actual water volumes, no weighing
- WF accounts offer basis for impact assessment and
formulation of sustainable water use strategy
Hoekstra, 2009
23From water footprint accounting to policy
formulation

- Spatiotemporal-explicit water footprint of a
- product
- individual
- community
- business
- Impacts of the
- water footprint
- environmental
- social
- economic
Reduce and offset the negative impacts of the
water footprint
Hoekstra, 2008
24Shared responsibility and an incremental approach
- Consumers or consumer or environmental
organizations push businesses and governments to
address water use and impacts along supply
chains. - Some businesses act voluntarily in an early
stage. - Governments promote businesses in an early phase
and implement regulations in a later phase.

26Policy Cycle
27Policy Process in Context
28Why Information is important
- Legislation changes (EU, UK etc)
- Regulatory enforcement
- Technology changes
- Process technologies
- Management techniques, standards
- End of Pipe
- Organisational importance of decisions and
foresighting - Influencing negotiations,
- Win win

30Information for Decision making
31Define the problem
- Take time to properly define the problem
- What is the issue?
- What is the problem?
- What decision needs to be taken?
Major Effect
32Find the information
- Determine source of information
- What info is needed
- Who has the info?
- Why is the source collecting that info ?
- Which component of the problem will it help?
- Evaluate the source !
33Process the knowledge
- Gather match with the problem
- Extract organise
- Which part needs to be used
- How can it be presented
34Process the knowledge
Information collected
Additional information needs
Usable Information
Value adding to information
Information required for decision making
35Taking the decision
- Form an opinion, for its effectiveness
efficiency - Take the decision
- Has it helped solve the problem?
- Did it take into account all the views of
concerned parties ?
36Taking the decision
problems
Decisions
Implementation (actors actions) and monitoring
and evaluation are integral parts of decision
making
37Sources of Information
Books, articles, etc
- Internet
- Caution its unregulated
- Peer to Peer networks (talk to people !)
- Professional Bodies
- Official bodies
- Government departments,
- Regulators
- Commercial sources
Information products / services
Raw data
38Range of Policy Approaches
39Soft Path
- The soft path for water is a comprehensive
management and planning approach. - unleashes the full potential of demand
management by simultaneously changing water-use
habits, technologies, and practices. - Working within ecological limits, local public
participation to ensure sustainability of water
resources. - Source Brandes O. M. and Brooks D.B.(2005) The
Soft Path in a Nutshell, POLIS Project of
Ecological Governance, University of Victoria
40What good looks like
- Introduction
- Comment on the subject (what do you understand by
it? How is it important? Etc. (10 of word
count) - Main Body
- Develop your line of argument through several
main ideas (perhaps 3 or 4) - Support your ideas/arguments with examples and
illustrations drawn from your own research,
reading and the course material. Policy
Development is based on evidence. Show you know
how to use it - Conclusion
- Make you final point
- Summarise your main ideas and attempt a firm or
tentative answer to the question - Indicate the wider/further important implications
of your findings and possible further research
(20 of word count)
41Content Guide
- Do
- Have a clear introduction set the scene a map
for the reader - Structure the assignment in paragraphs move
seamlessly through your themes and issues - demonstrate skills of analysis and interpretation
- Provide evidence
- Clearly reference your work
- Summarise your findings in a clear conclusion
- Include a list of references/bibliography
- Proof Read your assignment before submitting
- Include a Cover Sheet
- Do NOT
- engage in unnecessary narratives
- Plagiarise !!
42The Module Assessment
- For a region of your choice, prepare a report
discussing water policy options available to the
relevant authorities to achieve good water
quality and public health. Your report should
include proposals for policy responses including
any behaviour changes required from the
population as a whole to the issues you discuss.
