Suggested Answers; a. Type of agriculture
and its general characteristics
"It is a typical example of plantation farming. It reflects the general character- istics of such a type of farming as below:
Location in the tropical are a
The sample farm is 25km from Malacca. It shows that it lies in
tropical region. Plantatious are usually practised in tropical regions, on fertile alluvial soils.
2) European ownership
The farm is now owned by Dunlop Ce. which is a European
company. It reflects one of the character-
istics that planta-
tions are mostly
owned by European
countries. Usually
this form of
cultivation was first
taken by white people in their colonies.
After the Industrial Revolution in the western European
countries, the demand for tropical products increased steadily. With their immense
capital, the European established farms in the tropical coastal regions.
3) Large size
The size of the farm is 2,200 ha., which covers quite
large area. It reflects another
characteristic the plantations, which are cleared out from the dense tropical rainforest, are usually very large in size.
Efficient management
the The work on farm is usually well organized, e.g. five managerial staff are employed in the sample farm. Great emphasis is laid on the efficiency of cultivation and the equipment employed. Generally, besides providing for nursery beds setting up laboratories, using farming machinery, the entrepreneurs also established factories for primary processing or packing of the products.
5) Native workers
employed
A lot of native workers are usually employed as reflected by the sample farms: there are 150 general labourers and 600- tappers of which 40% is Malay, 40% Chinese and 20% Indian. Natives are employed. as labourers in plantations since the white people cannot stand the tropical climate. Monoculture
The sample farm is specialized on the growing of rubber trees only. The characteristic of monoculture is applicable to all
plantations. Usually only one or two crops are selected.
7) Systematic and
scientific work
Using the sample farm as an example, the fields are systematically divided into areas yielding rubber, areas with replanted but immature trees, areas of old rubber trees, and areas· of·· being cleared. It reflects that works on plantations are usually systematic.

The o2tate" is divided into three divisions with oue village in each. The estate has also clinic, school and temple. It reflects that in plantations there are usually villages for the accommodation of the hired labourera, with facilities, like markets, schools, co-operatives" scattered all over the farms.
Export orientated
or
The estate is owned by Dunlop Co. European company of which the products
are sold all over the world. It shows that
the products of plantation farming are maitly for exports or are intended for sale in the international market. There are also roads to facititate the
transportation of
ps for export.
Future development
In recent years, many of the former colonized countries became independent. After the European
plantation owners have left the country, local management becomes inefficient, The plantations either continued operation under government. control or become divided into small holdings owned by the native farmers;

Suggested Answers:
a. Favourable conditions

1) Temperature
Rice growing requires 4-6 month growing season, with average temperature around 250 and heavy rainfall over 1500mm or equivalent in irrigation. The temperatures in the Central Valley are High all the year. Double cropping is

tes in the season and irrigation water can he easily obtained from the Menan Chao Phraya and its tributaries, which drain across the whole lowland area,
2) Relief and soil
The Central Valley Is a depression of vast stretches of afluvial lowlands, which allow large fields of rice cultivation, The
Menam Chao Phraya
and its tributaries, not only supply:
Irrigation water as mentioned above, but also leave behind ́s vast quantity of extremely fertile soil, which are most ideal for the cultivation of rice. The soil fertility is
replenished every year by the annual flood.
Labour, supply
Plenty of cheap labour is available For the ploughing, transplanting and harvesting.
Problems faced by the rice farmers.
During the season of high water from.
Hay to Sept., the
whole area is liable to extensive flooding. Although this............ sometimes helps solve. the problem of insufficient rainfall in this rain-shadow area and rejuvenate the soils, however, the length of flood season and the depth of flood water vary considerably from place to place and from year to year. The flood water is sometimes too little for rice growth. O the other hand, it may rise to 5-5 metres high to cause serious damages to the crops.
Furthermore, the over-dependency of rice growing on the seasonal rain and the river flood also results in the fluctuation in rice yield as well as rice prices.
Measures undertaken by the government
Several modern irrigation works have been constructed to solve the flood problem and to engure a certainty of water supply, The main scheme is the Greater: Chao Phraya Project which includes a large dao across Chainat and fourteen smaller ones down-stream. Large net- works of inundation and distribution canals with pumps during the period of low flood flow. These have brought large pieces
