Water Crisis - Coggle Diagram
Water Crisis
WHAT CRISIS?
Sustainable Development
Brundtland Report (1987), defined sustainable development for the first time
3 pillars: Environment, Social and Economic
(see notes for Venn diagram)
- water links very explicitly to this diagram
a world where poverty & inequality is endemic (regularly found), will always be a world where environmental and other crises occur.
Tragedy of the commons
water is life as needed by all organisms to live. BUT it's a 'common good' / 'free good' - meaning it's a public resource
-
explanations:
it's not a personal possession and the consequence is diffused as everyone is affected by this overexploitation
free/ not reasonably priced, people don't really mind wasting it as it's cheap and there appears to be so much of it
it's not something that we are forced to put in effort into obtaining, so we dont take good care / cherish it - it's almost too "easy"
Conflicting Water Needs
the increase in water needs of one area compromises the ability for the needs of other areas to be met: is there enough good quality H2O to go around?
Human Needs/Uses
drinking (physiological processes), industrial (coolants), agricultural (irrigation), hydropower (dams)
-
-
The Problem
H2O is overexploited and badly managed (as a common good) in terms of volume & waste disposal systems
only recently aware of significant feedbacks to humans via ecosystem services (that we highly depend on)
Poor water legislations
-
no reasonable water pricing
- too cheap, doesn't reflect it's ecological cost
- e.g. in Malaysia, anyone can take water from a river even if it negatively impacts downstream users
-

WATER CONFLICT
-
-
Water Wars?
-
Current anxiety towards global peace and stability
- natural to worry about water-related stresses
some history of conflict over water, few wars have been fought specifically over water, only in small scales are is unlikely to lead to national conflict.
the 'past as predictor of future' logic is compelling and comforting but dangerously myopic (lazy, foolish, uncritical criticizing)
the future may look nothing like the past: population growth in an area of climate extremes -> increases stress and demand which all in turn exacerbates the crisis
CONCLUSION
water quality issues have decline in significance, major issues rn are related to water quantity:
- flood and droughts that developing countries are not as capable to cope with
Local problems but global solution = climate change
- cannot be solved by building more/larger dams or flood defence systems
- focus on protecting, cleaning, conserving reservoirs and aquatic/freshwater ecosystems
many newly developing countries face major water quality problems, akin or even worse than those experienced by western Europe during industrial rev.
- may lack infrastructure, expertise, resources or willingness to act upon the crisis (corresponds to the difficulties in biodiversity conservation in the 3rd world)
WATER QUALITY
-
New Contaminants
pharmaceutical products
-
skin care, hygiene products being washed down the sink
microplastics
skin care, washing clothes
on average, we ingest enough microplastics in a week to make a credit card
current waste water treatment plants are very poor, and not equipped to remove these new pollutants therefore we risk ingesting it daily
others:
- AFFF (Aqueous Film Forming Foam - carcinogen),
- Microbeads
- Industrial chemicals
- illicit drugs
- PFOS (higher cholesterol, changes to liver function, reduced immune response)
- Cyantoxins (by cynobacteria - skin rahses)
