Flashcards in Climate and population Deck (18):
1

how many people live in the monsoon climates?

over half of the worlds population live in the monsoon climates

2

where is the polar tundra?

north of continents around arctic circle on edges of land masses

3

what is the climate like in the tropical monsoon?

-tropical monsoon climates have a monthly mean temp of above 18degrees
-feature wet and dry seasons
-wet season = may - oct - overhead sun heats land causing a low pressure system and air rises sucking in moist air from sea bringing heavy rain

4

what is the climate like in the polar tundra?

-characterised by a lack of warm summers
-average temp of less than 10 degrees
-sun shines for long hours in summer and few hours in winter
climate is cold

5

importance of tropical monsoon climate

if importance was measured by how many people affected then the tropical monsoon climate would be the most important in the world

6

importance of tundra climate

not as important as due to lower population

7

human acitivies in tropical monsoon

tourism
farming
fishing
highly populated

8

human activies in polar tundra

fishing, adventure tourism and mineral extraction rather than land based activities dominate

9

dependece upon the monsoon climate

sustinence farmers survival depends on seasonal nature of climate because of rice
nothing is wasted

10

dependence upon polar tundra

this climate has supported nous people sustainably for many thousands of years

11

explain how climate change will affect the way people in monsoon regions live and farm?

-weak monsoons can lead to crop failure
-people may move away

12

explain how climate change will affect the way people in tundra regions live and farm?

if permafrost melts it could release methane on a large scale enhancing greenhouse effect
if permafrost melts there may be potential for crops
animals may move around more

13

what is food security?

exists when all people at all times have access to sufficient, safe nutritious food to maintain a healthy lifestyle

14

what are the main challenges agriculture faces from climate change?

increase in temp
floods
droughts
sea level rises

15

what is climate smart agriculture?

an intergrative approach to address the interlinked challanges related to food security and climate change

16

social
economic
environmental strategies

E- by sustainably increasing agricultural productivity

S-change by adapting and building the resillience of agriculture and food security

E- means reducing and/or removing greenhouse gas emissions from agriculture

17

where may agriculture be at particular risk?

asia-pacific region as CSA does not seem to have taken routes at all only japan vietnam and phillipines are memebers

18

interventions of indian agricultural research institute IARI

superior seed varieties were tested and successful ones made available through village seed banks
heat stress tolerant crops made available
conservation farming practices introduced
underground pipelines
