3.4 adaptation strategies Flashcards
examples and understanding
what consists of structural adaptations
involves construction f physical structures to ensure water and flood management like:
1. sea walls
2. polders
3. water storage tanks
what does a sea wall do?
prevents water from advancing
and hence leads to protection against coastal flooding
what is a polder?
water from low-lying land gets pumped through a pumping station and up the dyke which acts as a all and the water is then drained at sea level
what does water storage tanks do
store excess stormwater and prevents flooding as it slows down water from rushing into drains/canals
example of polders
in the Netherlands its very common as they have been building them since 12 century and hence it has helped them stay protected from river and coastal flooding
examples of water storage tanks
Stamford detention tank [sg]
it allows excess water to flow and be stored temporarily, once water levels decrease, the water in the tank is released back in the drains
wat are the limitations of structural adaptations?
cost of construction is very high
maintenance cost of maintaining the structures is high
there may be displacement of people living in the coastal areas
what is technological adaptations?
help communities remain food secure despite changing climatic conditions, this increases food security and community resilience
examples of technological adaptations?
Singapore 30 by 30 plane
-aims to increase local food supply to meet 30% of residents by 2030
sg food depends 90% on imports, aims to reduce this reliance
less than 1% of land is available for farming –> funding for development of high-tech farms.
how is high-tech vegetable farms efficient?
monitored remotely to ensure grown in optimal conditions
harvested in shorter amount of time
how is high-tech egg farms efficient?
automated so that eggs can undergo checks faster
manpower can be allocated to other needs on the farm
how is high tech fish farms effective?
high tech water tanks monitor water quality and check for diseases
prevent spread of diseases
limitations of technology?
highly expensive
not all countries have the funding [country specific]
30 by 30- $40mil used to fund 9 farms
what are social adaptations
by raising awareness and educating communities
build community resilience and decrease vulnerability to impacts
examples of social?
in Nepal, to cope with prolonged droughts, communities are taught to plant more drought-resistant crops like apples
in Singapore, public educated on what to do when there is a flash flood or prevention of heat stress and hence reduces risk of injuries
