Can you think of any limitations / problems with specialization?

Limitations of specialization (p.14)

• Farmers my suffer from huge loss when there is crop failure or price fluctuation

• As pests and diseases can sprad more easily with the same type of crop

• Monoculture will cause depletion of soil nutrients

Open Ended

What are some other possible advantages of greenhouse farming / using machines and introducing high yield species? GIVE TWO advantages.

Advantages of modernation (p.13)

• greenhouse farming can minimizes impacts of adverse weather

• The use of machines can compensate the loss of farm labour

• High yield species increases farm output and farmer's income

Open Ended

What are some limitations of modernation?

Limitations of modernation

• High costs of investment

• Farmers may lack of technological know-how

• Limitations of machines, e.g. some cannot be use on hilly terrain

More about hydroponics

What are some of the characteristics and advantages?

Open Ended

What are the advantages of hydroponics?

Advantages p.13

• maximize the use of space / land

• ensure high yield and quality

• growing season is extended

• With better quality, farmers can sell them at a higher prices --> increase farmers' income

• These methods help conserve water and soil. Thus, environmental pollution caused can be minimized.

• They can limit disease transmission since plant-to-plant contact is reduced

Vertical farming

usually practice in urban area where land competition is very keen

Aeroponics

•Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium

Question b

The gross value of agricultural output increased. It is due to the increased in output % of fruits and vegetables (market gardening produce).

They are both high-value fresh produce.

Besides, the number of farming technicians have also increased by around _____ times.

So there is more technical support / more application of scientific and modern farming technologies which ensure a higher output.

Photo 4d shows a modern farming method in ZDR.

(c) Identify this modern farming method.

Multiple Choice

(c) Explain how it is related to the changes in area of cultivated land and number of agricultural technicians shown in Table 4c.

The area of cultivated land has _________.

• increased

• decreased

Open Ended

(c) Explain how it is related to the changes in area of cultivated land and number of agricultural technicians shown in Table 4c.

The area of cultivated land has decreased and the use of hydroponics ................

(c) Explain how it is related to the changes in area of cultivated land and number of agricultural technicians shown in Table 4c.

The area of cultivated land has decreased and the use of hydroponics is less space-demanding. It can better utilize the space / can maximize the use of limited land
