agriculture

Question 1

what are agricultural activities similar to

Answer 1

to natural ecosystems as they rely on environmental characteristic to survive

Question 2

how do humans supplement natural environments

Answer 2

through farming processes such as irrigation, genetically modified organisms and fertilisers

Question 3

what is the negative of these supplements

Answer 3

these supplements come at a cost, financially and environmentally, and require greater quantities of fossil fuels

Question 4

where is shown to have the most increase in agricultural land cover

Answer 4

Northern hemisphere shows the most increases in agricultural land cover with warmer and moister climates expected in high latitudes

Question 5

positives of agriculture

Answer 5

the agricultural growing season will expand significantly, and new plant and animal species will thrive

Northern Russia is expected to have a 150% increase in arable land due to climate change, with the number of frost-free days increasing by up to 20 days per year

additional CO2 stimulates plant growth only if all other requirements are met

Question 6

negatives to agriculture

Answer 6

climate change is affecting the availability of water and nitrogen, which affects the environment and agricultural productivity

farmers may benefit from higher rainfall and longer warm seasons in the short term but also face negative consequences such as increased weeds, invasive plant species and insect pests.

water availability will be significantly impacted, requiring more intense irrigation due to heat, drought, and water scarcity

Question 7

what are areas in lower latitudes expected?

Answer 7

areas such as Namibia, Botswana, Mexico, India, Thailand and Australia are expected to see a decline in arable land and crop yield due to temperature increases and decreases in rainfall

Question 8

what are agricultural areas in australia becoming unsuitable for agriculture leading to

Answer 8

leading to migration of production towards more reliable rainfall and moderate temperatures

Question 9

why are agricultural activities and land cover within southern Europe projected to decline

Answer 9

due to reduced suitability, shifting and expanding into Northern Europe where new areas of arable land will be available

Question 10

why is there an increase in the frequency and intensity of natural hazards

Answer 10

due to climate change is impacting agricultural environments, such as the Australian bushfires in 2019-2020 and floods in 2022 causing significant crop damage, livestock loss, and infrastructure damage
