Adapting To Change: Water Storage

Question 1

Why might water storage be a better solution than virtual water?

Answer 1

Importing food is expensive and insecure

Better as a short-term solution

Question 2

Why will global warming result in more blue water being in circulation?

Answer 2

More water liberated from ice and snow

More evaotranspiration

Question 3

Why is water storage a good option in a changing climate?

Answer 3

Exploit the few high intensity rainfall events for time of decreased low/med intensity events

Question 4

How do grey and sadoff (2007) define climate resilience?

Answer 4

It’s related to the ability to store fresh water in times of surplus to use in time of drought

Question 5

How does this show a problem with current water stress index ?

Answer 5

They do not reflect this

Question 6

Are forms of water storage always man made and large scale?

Answer 6

No: Bangladesh use groundwater-fed irrigation to produce high-yielding boro rice during the dry season which is then replenished by monsoon rains

Question 7

What is the problem with the fact that water storage could be a good solution?

Answer 7

Countries who need a high level of infrastructure development to adapt to water scarcity are often those who have a low ability to invest

Question 8

What do today’s countries trying to achieve water security face that previous countries didn’t?

Answer 8

• more difficult and infrequent hydrologies
• larger populations
• more varied water demands
• greater understanding of social and environmental costs, and therefore responsibility to minimise them

Question 9

What else can complicate the task of achieving water security?

Answer 9

Trans-boundary waters

Question 10

What can exacerbate the risks to water security posed by climate change?

Answer 10

Violence and conflict

Question 11

What temp changes will be seen in the Gaza Strip?

Answer 11

• precipitation decrease of 35% with significant seasonality
• warming between 2.6 and 4.8 degrees
• a tendency towards drought and desertification

Question 12

How has conflict worsened food insecurity?

Answer 12

• resource assets eroded by effects of conflict
• the Israeli closure regime affects Palestinians ability to adapt to climate risks
• unstable governance
• Israeli restrictions prevent bulk imports of water into gaza

The presence of short-term enforced coping prevents development of long-term adaption
