41. Rubber growers in westen

Malaysia are facing with increasing difficulures, Mr. Brown, an owner of a rubber plantation along the western foothills, said in a recent Interview:

"In the past, planted rubber in all my fields, but now 1 plant it on only 65% of the land. I grow other the rest of

cash crops

my land."

a. With reference to the shove

diagrams, give an account the favourable conditious which used to encourage Mr. Brown and other plantation owners to grow rubber as a major cash crop in the western foothills of the Malay Peninsular.

b. Explain why they live to

diversify their crops.

Suggested Answers:

. Favourable conditions for

rubber plantation in W. Malaysia

-----

1. Temperature and Bainfall

W. Malaysia is located within the Doldrums. The temperature is constantly high, with an overage round 26°C, Rainfall is heavy and evenly distributed all year, totalling to around 2000

to 2500mm. This hot and moist condition is suitable for rubber growing. Though there are usually heavy downpours in the afternoon, mornings are clear for tapping. The growing season is long. 2. Sheltered

Shade and shelter are

important for the rubber

tree, especially in its

early stage. The western

coasts are sheltered from

the monsoon Windy -- the NE

winter monsoon 15 sheltered by the Main Range ajul Bise

MS

SW monsoon 19 sheltered by

the Sumatran Mountain,

3. Well-drained soils

Rubber tree grows well on well drained lowlands or undulating land. In Malaysia

the well-dralued Coothills on the westeru side of the Main Range form suitable terrains, Rubber is extended to the coastal lowland where the drainage is under control.

4. Cheap labour and efficient

techniques

Rubber growing requires a large cheap labour forea since there. are many tasks involved in running a plantation. It is also desirable for some of the Jahour to be skilled in tapping the trees. In western Malaysia, there large cheap labour force from immigrants and scientific techniques of the British who formerly controlled most of the plantation,

5. Easy communication

is

A

Rubber is export- oriented, so an easy communi- cation network is desirable. The western foothills of K. Malaysia are well above the flond lowland. Main roads and railways have been constructed along these drier areas to link up the great seaports such as Singapore and Poft Swettenham to facilitate export.

K

o, Stable government

The stable government attracts foreign capitals and skilful labour, e.g. the overseas Chinese.

7. Markets

Favourable world markets exist, U.S.A. is the largest consumer of rubber for making

motor-car tyres,

b. Deasons for the diversification

It is a general treud that many of therubber growers have now diversified their crops as the profit from rubber growing falls. It is mainly due to Chie keener competition from synthetic rubber that results in the fall of the demand of natural rubber, as the deman decreases, price falts and profit becomes less, The rubber growers, of course, are directly affected, but the economy of the country will be threatened ton. Therefore, diversification is greatly encouraged, Besides other plantazion crops suck as oil palm, coconut and pineapple, crops are particularly important as the country still has to import a lot of food.

4. Advantages of mixed farming

The diagram is an example of a mixed farm, Mixed farming is a Com feature in the wheat belt of Australia. In recent years,

most of the farms there

combine extensive wheat farming with the growing of ather crops and the rearing of sheep, either for their wool or their neat, Mixed farming 18 practised there because of the follo

reasons:

1. In the farm, cultivated,

land is divided into paddocks up to 42 hectares in size, The paddocks are used for the growing of wheat and pasture, and soubsA C are left falow,munio evidences suggeste crop rotation and Fandyes. rotation are most probably found there. Notation is practised there in order to check soil erosion. Soil exhausts easily underb monoculture. If the same" kind of erop is grown year- after year on the same pièce of land, after a certain period, the soil fertility will be deflected and the yield of the crop will become lower and lower, By the rotation of crop with regular fallow period, mojl fertility can be retained- and a higher wheat yield is possible.

2. Since, the soil is more

fertile, pasture for sheep can be improved.

3. The diversification of

4. After harvesting the vheut,

the stubbles can be

utilized to feed the sheep, 5. The sheep grazing on the

land produce was to products. which are good fertilizers for the soil.

6. The work on the farm is

spread evenly throughout the year since wheat is BOWN IN inte autumn and winter and harvested in aurer, while shearing and lambing take place in spring.

b. Differences from an average

form in Wong Kong.

1. The mixed farm, with a

total area of 275 hectares, is much larger than the farms in Hong Kong. Many farms in Hong Kong are less than one'hectare.

2. The land of the farm is divided into paddocks in which a single type of crop is grown. In Hong Kong, several different types of crops can be found growing
