Uk Challenges Flashcards
Challenges posed by population grothv
Over next 30 years uk pop to increase by 15%
Pop growth will lead to a high demand for houses food, this may lead to strain on Uk resources as deamnd is too high and overweighs the supply. In addition as pop grows demand for coal and oil increases this increases pollution. Gas is projected to decrease .
Cause destruction of habitats because renewable energy sources take lits of space
Strain nservices
Factors which could make population projections unreliable
Uk pop expected to be 73.2 m by 2025
Pandemics- lead to fatalities
People having lots of children
Incorrect assumptions about fertility and morality
Migration volume changes
Incorrect or slightly inorrect starting data
Population variation over UK
•Not evenly distributed e.g London has double the population than the Souht east
East has largest pop change of 6 and south west about 4
Stresses pop growth leads to
Housing- reasons:
People staying single for longer
Divorce
Living longer
Natural increase
Demands that will put pressure on UK ecosystems
•Increased demand for Energy- As UK invests in renewable energy , our natural landscape will changed as wind turbines and solar farms are built . This will affect areas if high altitude (heartland and moorland) but also marine eco stems
•Increased dreamland for hosuing- Destrous open spaces+ habitats destroyed due to increased surface run off and erosion due to impermeable surfaces preventing drainage
•Demand for food- water resources- puts pressure on local water systems due to increased consumption. More ares need built for food + water e.g farms and water storage=destroys habitats
•Increased waste- need more landfill sites
Meghan gas produce from decomposition- explosive+ dangerous
•Incineration + gases released Whig may cause air pollution = acid rain
Wastes energy+ money throwing things away
Green field V brownfield
-Brownfield-
Pros
Found in urban areas so reduces demand on car use
•Services: water, electric, gas already in place
•Uses unslightly ares+ redevelops them; improves the urban environment
•reduces urban sprawl as site had been previously developed
Cons
Close to poor quality hosing (may not appeal to wealthy people)
•Old buildings have to be cleared + land cleaned of pollution
Greenfield
Pros
•Healthier environment
•Cheaper + quicker to build on
Cons
Wildlife+ habitats lost or disturbed
Reduces area of farm+countryside
Encourage urban sprawl, so not encouraged by environmentalists
Often far from work + services Generating traffic
Greenbelt
Heavily protected land circling an area to prevent urban sprwwll
Greenfield sites
Land which has not previously been built on before
Brownfield sites- land that has been built on before
Migrant
People moving home within and between countries
Emigrant
Existing form one country to become an imagrant
Immigrant
A person who ones to live in a foreign country permantaly
Stakeholders
A person (or group) with an interest or concern in something
Suburban sprawl
An increase in the expansion of urban areas into countryside (suburbs)
Net migration
Difference between people arriving tan leaving a country
Two speed economy definition
- one part of a country grows much quicker than the other
Unsustainable transport
Using non renewable energy e.g petrol driven cars+ lorries = air pollution
Sustainable transport
Using renewable energy and zero emission
Private transport
Individual modes of tranport + private cars , private aircraft
Public transport
Tranport that carries large volumes of passengers e.g. trains , buses, commercial planes, ships
Congestion charges
Paying for access to an area or route
Sustainability
Sustainability is the practice of using natural resources responsibly, so they can support both present and future generations.
Sustainable transpornt(in detail )
Challenges
- Emissions leading to global warming come from energy consumption e.g 33% of electrify , 28% transport , 20% neutral of consumption
- Local (road side) air pollution impacting on health e.g London7.3-8.3% deaths due to air pollution
4 solutions - London
•London underground - extension of Jubilee line has encouraged more people to use public transport
•Oyster cars - integrated travel payment method , people can gain access to rapport quickly
•Encoruaging styling - bike sharing some - hire bike for £2 for short journeys- horse bike s
•Congestion charges- private vehicles pay to access CBD to reduce pollution levels . £11.50 between 7am and 6pm Monday-Friday
•Car sharing
Why do people use private tranport
Can go on journeys when they please
Able to have prat convo
Closer to home
Feel safe
Can be quicker- no stopping
Staycations National parks- sustainability plans
