Flashcards in Climate and population Deck (18):
how many people live in the monsoon climates?
over half of the worlds population live in the monsoon climates
where is the polar tundra?
north of continents around arctic circle on edges of land masses
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
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
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
importance of tundra climate
not as important as due to lower population
human acitivies in tropical monsoon
human activies in polar tundra
fishing, adventure tourism and mineral extraction rather than land based activities dominate
dependece upon the monsoon climate
sustinence farmers survival depends on seasonal nature of climate because of rice
nothing is wasted
dependence upon polar tundra
this climate has supported nous people sustainably for many thousands of years
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
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
what is food security?
exists when all people at all times have access to sufficient, safe nutritious food to maintain a healthy lifestyle
what are the main challenges agriculture faces from climate change?
increase in temp
sea level rises
what is climate smart agriculture?
an intergrative approach to address the interlinked challanges related to food security and climate change
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
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
