With reference to the above diagrams, give an account of the favourable conditions. 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 Peninsulary
6. Explain why they have to
diversify their crops.
Suggested Answers::
A. Favourable conditions for
rubber plantation in W. Malaysia
1. Temperature and Rainfall
W. Malaysia is located within the Doldrums. The temperature is constantly high, with an average round 26°C Rainfall is heavy and
evenly distributed all year;
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 iroportant for the rubber tree, especially on its early stage. The western coasts are sheltered from the monsoon winds the NE winter monsoon is sheltered by the Main... Range and the SW monsoon is sheltered by the Sumatran Mountain.
3. Well-drained soils -
Rubber trèe grows well on well drained lowlands or undulating land. In Malaysia the well-drained foothills on the western side of the Main Range form suitable terrains. Rubber is extented to the coastal lowland where the drainage is under control.
4. Cheap labour and efficient
techniques
Rubber growing requires a large cheap
labour force since there are
many tasks involved in
running a plantation. It is also desirable for some of the labour to be skilled in tapping the trees. In
western Malaysia, there is a large cheap labour force. from immigrants and scientific techniques of the British who formerly controlled most of the plantation.
Easy communication
Rubber is export oriented, so an easy communication network-is desirable. The western foothills of W. Malaysia are well above.the: food Jowland. Main roads and. railways have been constructed along these drier areas to link up the great seaports such as Singapore and Port Swettenham to facilitate export
6. Stable government
The stable government attracts foreign capitals and skilful labour, eg, the overseas Chinese," Markets
Favourable world markets exist. U.S. A. is the largest consumer of
rubber for making motor-car tyres.
b. Reasons for they diversification
It is a general trend that many of the rubber growers have new diversified their crops as the profit from rubber growing falls. It is mainly due to the keener competition from synthetic rubber that
results in the fall
報日僑華
of the demand of natural rubber. As the demand decreases, price falls and profit becomes less. The rubber growers, of course, are directly affected, but the economy of the country will be threatened too. Therefore, diversification is greatly encouraged. Besides, other plantation crops such as, oil palm, coconut and pineapple, food crops are particularly important as the country still has to import a. lot of food. 42. Below shows a plan of a
farm in the Murray-Darling Basin in Australia.
a. Give a reasoned account of
the farming activities which are carried on in this farm, b. What are the main.
characteristies found in this farm which cannot be found in an average farm in Hong Kong?

Suggested Answers:
a, Advantages of mixed farming
The diagram is an example of a mixed farm... Mixed farming is a common feature in the wheat belt of Australia. In recent years, most of the farms there combine extensive wheat. farming with the growing of other crops and the rearing of sheep, either for their wool or their meat. Mixed farming is practised there because of the following 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 some of them are left fallow, These are evidences suggesting that crop rotation and land -- rotation are most probably found there. Rotation is practised there in order to check soil erosion. Soil exhausts easily under monoculture. If the same kind of crop is grown year after year on the same y piece 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, soil 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 farming practice can⠀ gurantee and increase the income farmers as well. Even though there is a crop failure, the loss incurred can be compensated for by the sale of wool,
4. After harvesting the wheat, 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 sown in late autumn and winter and harvested in
summer, while shearing and lambing take place in spring.
b. Differences from an average
farm in Hong Kong ⠀⠀
1. The mixed farm, with a
total area of 275 hectares, is much larger than the: farins in Hong Kong, Many farms in Hong Kong are less than one hectare, 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. on a small plot of land. 3. Crop rotation and land
rotation are practised there. Some land is left fallow for the recovery of fertility. In Hong Kong, except the abandoned land; land belongs to a farmer is fully utilized. Usually the harvest of one crop is immediately followed by another. Sometimes fallow land may be found, but is only for a very short period. of time,
The wheat frown on this farm is grown as a kind of commercial crop, while wool of the sheep which fed on the pasture also enters international trade. Farming in Hong Kong is mainly subsistence. The products from an average farm in Hong Kong account for only a small percentage of local consumption.
5. The standard of living of the owner of this farm'is high while in Hong Kong, the life of farmers is usually poor because the farms are too small to be worked at a profit..
6. This farm is highly.
mechanized, Wheat is: harvested by combined harvester and wool sheared by electric shears. In Hong Kong, farms are too small
to be mechanized, Farmera
