Paper 2 sustainable development Flashcards
what is a sustainable city
one that meets the needs without making it more difficult for future generations to meet their needs
how do sustainable cities put pressure on the natural environment
by using food, water and energy and producing waste and pollution
how can living in a city be more sustainable than living in the countryside (3)
fewer road journeys as everything is close
careful planning helps save resources
people work together to generate ideas and resources
what are a cities input
things we use - water, food, energy and resources like timber, concrete
what are a cities outputs
what a city produces - waste, sewage, pollution
how can we measure the impact of cities on the environment
use an ecological footprint
how big is an ecological footprint compared to size of city
always larger than the city - they spread globally to where inputs come from and outputs end up
what is an ecological footprint
an area of land or sea needed to produce all inputs a city uses and dispose of outputs
how can cities become more sustainable ( 5)
recycle more waste, improve public transport, more green spaces, local energy schemes and more cycling routes
what are the social economic and environmental benefits of cycling (3)
all contribute to a sustainable city
1 social - daily exercise, positive mental health, reduces sick leave from work, lowers obesity, more people on streets so makes it safer
2economic - quick reliable transport, improves access to shops, boosts tourism
3 environmental - reduces pollution, reduces co2 emissions
why do people cycle in cities
get to city for work or shopping, site seeing, get to work or school
what is CYCLE Strategy
network of cycle routed through a city avoiding traffic
