Question 1

How does Climate affect productivity and the types of food that can be grown?

Answer 1

Regions experiencing extreme temperatures and rainfall struggle to produce food.

Question 2

How does climate change affect global farming patterns and productivity?

Answer 2

• Weeds and pests will thrive in warmer conditions.

Question 3

How does technology affect food yields?

Answer 3

• The poor use of irrigation can lead to waterlogging and salinization In HICs, mechanisation and agribusiness give high levels of productivity.

Question 4

How does rising global temperatures affect farming

Answer 4

• Rising global temperatures cause pests and diseases to spread north and south- from the tropics.

Question 5

Answer 9

Plants are sprayed with fine water mist containing plant nutrienets. Excess water can be collected and re-used.

Question 10

What are hydroponics?

Answer 10

plants are grown in gravel or mineral-rich water.

Question 11

What is biotechnology

Answer 11

Biotechnology uses living organisms to make or modifyp roducts or processes. In farming this includes the development of genetically modified crops.

• Over half the worlds soya beans are gm
• GM oilseed rape is widely cultivated in Canada.

Question 12

What is appropriate technology

Answer 12

Means using skills or materials that re cheap and easily available to increase output without putting people out of work.
- Eg a bicycle to de - husk coffee beans.

Question 13

List the first three advantages of the IBIS

Answer 13

• Improves food security for Pakistan, making 40% more land available for cultivation.
• Over 14 million ha of land is now irrigated.
• Irrigation has increased crop yields.
• Wheat 36%, Rice 39%, and fruit 150%.

Question 14

List the other four advantages of IBIS

Answer 14

• Diets have improved
• Fish farming in storage reservoirs provides a source of protein.
• Agriculture - based industries have developed, providing value-added good for export.
• HEP(Hydroelectric power) is generated by the rams.

Question 15

List the first three disadvantages of the IBIS

Answer 15

• Some farmers take an unfair share of water, depriving others downstream.
• High summer temperatures result in high water loss through evaporation.
• Poor irrigation techniques mean water is wasted.

Question 16

List the other three disadvantages of the IBIS

Answer 16

• Population growth will increase the demand for water in the future.
• High costs to maintain reservoir capacity, barrages and channels.
• High water levels have led to waterlogging in places.

Question 17

What is the IBIS

Answer 17

Is the largest continuous irrigation scheme in the world.

• It consists of three large dams and over a hundred smaller dams that regulate water flow.
• Over 64000 km of smaller canals distribute water across the countryside.
• 1.6 million km of ditches and streams provide irrigation for Pakistan’s agricultural land.
