371 Final Exam Flashcards
Primary hydrological link between land and ocean
Evaporation and precipitation
90% of evaporation is from ocean
% global water in oceans
97%
Biome with Highest annual variation in evaporatation and precip
Deserts
What is rain?
Water droplets that have condensate do to a condensation nuclei (aerosol particle)
Bergeron-Findisen theory
Rain is snow that passed thru a war layer of air and melted before it hit the ground
Water runoff
1/3rd water runsoff into the ocean
High mountainous runoff creates high streamflows
Can lead to floods or droughts
Hydro-social cycle
Humans manage every step of the water cycle, effect its efficiency and its aesthetic
Historical water management
- only focused on surface water
- monopolization of water market
- overpricing
- no regulation on/lisence needed for groundwater
- Water use in BC: disrupted evenly between agriculture, indistrial and drinking
- top-down, regulatory
Water lisences
- how water is allocated in BC
- FITFIR (first in time, first in right)
- limited supply of water therefore limited supply of lisences
- determines who gets to use water
- application checked for: Impact to existing licensees, instream flows, landowners, FN interests
- used to not have an expiry date - recently added
- “use it or loose it”
- seen by some as “giving into colonial authority”
Water Sustainabilty Act
Royal assent in 2014, Came into force in February 2016
Replaces old water act
Protects water flows and fish
Improves regulation around dams, well construction and compliance
Groundwater now regulated!
Cloud seeding
Spraying aerosols old into air to provide more condensation nuclei for clouds to form
- used to increase clouds in places with not enough water
- used to create snow for recreational purposes
Challenges with water licensing
- telling people to cut down in times of drought - they get scared and hoard water
- no groundwater regulation even tho 750,000 BC residents use groundwater for drinking water, agriculture, etc.
How many aquifers used by humans in BC
900+
Largest global user of water
70% used for agriculture
Water use distribution in BC today
90% land improvement, industrial use, agriculture, mining, 10% drinking
Gold Feilds Act
1859
First need to move water into arid regions
Allowed people to build water transportation infrastructure/large amounts of water
Water Act
Est. in 1909
People can apply for formal water licenses
-More than 8,000 claims made in first 10 years
-Does NOT recognize aboriginal rights and title
-primary water uses were argiculture and gold mining
BC drinking water protection act
1996-early 2000’s
Ban on large surface water exports out of BC
-Superior to all other water acts
-Says all water is property of the crown
-est. because of Walkerton, ON tragedy
-enforced by ceritifed provincial health authorities/water operators/1st nations health authorities
Challenges with water reform in BC
- 100 year old legislation, not relevant for present issues
- regulation is hard to enforce
- tools exist but aren’t used (ex. Fish Protction Act)
- Multiple levels of gov’t. And agencies are involved
Living Water Smart
Water conservation strategy up taken in BC in 2008
Goal: improve water laws to protect ecological integrity, more community involvement and groundwater regulation by 2012 (4 years late but oh well)
Uses online blog method for FN consultation - FN do not like it b/c many do not have Internet access
This strategy does not Reflect Indigenous rights, their relationship with water and their knowledge
Define: governance
The process of societal decision-making
WHO, WHAT and HOW
Accountability and power
Focuses on the end results
Define: management
Operational, on-the-ground activity to regulate a resource and the conditions of it’s use
Focuses on the process
Water governance + management change timeline
1850’s: industrial water use begins in BC
1909: water act
70’s-80’s: Canada is world leader in science
90’s: 21% DFO and 26% of Environment Canada cut to try to streamline/modernize water act, flow monitoring sites cut from 4,000 to 2,500
1996: drinking water protection act
2008: living water smart
2014: water sustainability act proposed
2015: 25 million in funding for water sustainability act
Feb 2016: WSA enforced
WHO does WHAT in water governance?
Federal and Provincial Have overlapping and hard responsibility
- federal has “pass the buck” mentality, province has most authority
- federal level very complex - 20+ agencies
- huge variation of provincial/municipal water regulations
- FN role and rights remain unsolved
Harmonization VS. Subsidiary
Harmonization: process of achieving clear, efficient and effective regulation by centralized and standardized policy
Subsidiary: when central authority does not take action unless they have too or unless it is more effective than action taken by lower levels of authority
Federal responsibilities
- pollution prevention/mitigation and EA
- infra funding
- water science + monitoring
- international disputes
- recognizing FN rights and title
- water use on federal lands
- fisheries and navigation
provincial responsibilities
- withdrawing and allocating water
- water licensing
- distributing authority to municipalities/regions
- water source protection
- wastewater & environmental management
Local resposibilities
- water providers
- land use planning
- storm drainage management
Mullholland Aqueduct
Opened in 1916
William Mullholland
Gravity-driven, innovative, allowed growth of LA
First ran from Owens Valley to LA
Owens valley lake dried up from overuse of water
“California water wars” began
2nd aqueduct built - dam broke and flooded Santa Clara and Ventura County
Now get water from Haiwee Resevoir
Benefits of dams, reservoirs and large water infrastructure
- flood control
- drought mitigation
- irrigation
- hydroelectric power
- economic power
- allows people to have a water supply in arid places
- ensures constant water supply to arid places
Cons of dams, reservoirs and large water infra
- blocks fish migration pathways
- withholds sediment from downstream ecosystems
- creates shallower reservoirs, warmer water temp, no fish and anaerobic conditions
- technical solutions that create more need
Flint, Michigan
Lead contamination in all water because of old pipes and corroding infrastructure
Lake Oroville, California
Rose 17 feet in 10 days from snow melt and runoff - big surprise in today’s drought conditions
world bank
Est. 1944 to help Japan and European countries rebuild after WWI
2 main branches of water management: sanitation and ecosystem health
Sanitation has always had higher priority than ecosystem water health
Global resource supply and demand
1.1 billion people without electricity
738 million without safe drinking water
2.5 billion without sanitation
55% more food needed in the next 20 years if growth rate stays the same
Millennium development goal #7
Every person will have access to safe drinking water by 2015
Sustainable development goal #6
By 2030, achieve universal access to sanitation, reduce proportion of untreated water, recycling and safe refuge
