Population and Environment NEW

Question 1

reasons for increase in food production.

Answer 1

-increased use in farming machinery
-increased farming resources e.g. pesticides
-better farming management

Question 2

what is the global pattern for food consumption?

Answer 2

an increase as population is increasing and they consume more food and a few countries average under 1750kcal per day

Question 3

why do HICS consume more than developing countries?

Answer 3

HICs having more money to import and invest in agriculture , as well as more money per person to buy food

Question 4

how does food consumption vary regionally (cereals)?

Answer 4

-50% of calories globally are from cereals
- In Africa and Asia, cereals account for up to 70% of energy intake , whereas in high income countries it is 30%.
-Rice consumption is highest in China and Eastern Asian countries

Question 5

how does food consumption vary regionally (meats)?

Answer 5

-Developed countries eat the most meat
-pig, sheep, cattle, and poultry are the main meats consumed in HIC regions
-Middle-East, India, and Africa, camels and goats are the dominant meat

Question 6

how does food consumption vary regionally (fats oils and sugars)?

Answer 6

-consumption is highest in HICS due to consumerist culture

Question 7

what is an agriculture system?

Answer 7

it produces yields through the addition of resources and processes. Seen as system as there are inputs outputs and processes.

Question 8

physical inputs in agriculture system.

Answer 8

climate
soil
location
pollination

Question 9

human inputs in agriculture system.

Answer 9

seeds and live stock
farming machinery
labour
fertilisers and pesticides

Question 10

processes in agriculture system.

Answer 10

arable farming:
planting seeds
harvesting
tending to land

pastoral farming:
tending to livestock
breeding
collecting produce

Question 11

what is agricultural productivity?

Answer 11

the amount of useful outputs (yield) in proportion to the amount of inputs, showing the efficiency of the farm

Question 12

what factors affect productivity?

Answer 12

type of farming:
-substinence
-commercial
-intensive
-extensive

-climate
-soil

Question 13

what is intensive farming?

Answer 13

-high input in relation to agricultural land to produce highest output possible

Question 14

what is extensive farming?

Answer 14

-low input in relation to agricultural land and producing lower outputs

Question 15

what is commercial farming?

Answer 15

-agriculture with the intention of providing yields that can be
sold commercially, making a profit.

Question 16

what is substinence farming?

Answer 16

-self-sufficient farming, where crops are grown only to
support those growing the crops family or community, with little or no profit.

Question 17

how does the climate affect productivity?

Answer 17

precipitaion,humidity,wind and temperature can have an affect.

Question 18

how do soils affect productivity?

Answer 18

issues with soil can affect productivity.

Question 19

how will climate change affect agriculture?

Answer 19

some places will become more productive whilst others becomes less productive.

-majority of the world will suffer from yield declines when areas like Canada, Europe and some of Central Asia will face yield increase.
-increase in extreme weather events likely to decrease productivity
-rising sea levels will cause flooding in low lying areas e.g Bangladesh
-

Question 20

define food security.

Answer 20

when all people at all times have access to enough safe and nutritious food required for a health life.

Question 21

what are the 3 stratergies to improve food security?

Answer 21

-improving food production
-increasing food access
-reducing waste

Question 22

what is the example of how technology has increased food security.

Answer 22

The Green Revolution- increases use of fertilisers/pesticides, irrigation and development of high yielding varieties (HYVs) increased yields in areas such as India.

Question 23

how many people experience chronic hunger globally?

Answer 23

1 in 10 people

Question 24

explain improving food production as a strategy of improving food security

Answer 24

new echnology (e.g. GM crops)
can increase the amount of
food being produced, which
therefore increases food
security as there is more
food available which may be healthy

Question 25

explain improving food access as a strategy of improving food security

Answer 25

access to foreign markets
means they can import food,
increasing food security.
e.g.trading blocs

Question 26

explain reducing waste as a strategy of improving food security

Answer 26

Waste can be reduced by
harvesting natural resources
and having better storage
