Geography Chapter: AgricultureY
• It is the growing of rice in flood fields. Rice can also be grown on terraces on hill slopes.
• 90 per cent of the world’s rice is grown in Asia while the other main rice-growing countries are Egypt, Italy, Spain, Brazil and the United States of America.
• Wet rice, or padi, is mostly grown in Asia because the high temperatures and rainfall are suitable for its growth.
Characteristics
1. Subsistence farmers, mainly for own consumption as it is their staple food.
2. Practice monoculture, growing of one main crop. They may grow vegetables and fruits to supplement their income.
3. Small Size. Varies from half to 2 hectares.
4. Labour intensive because there is a lot of work to be done from ploughing, transplanting of seeds, harvesting, threshing, winnowing and packing. (About 2 ½ times more than the cultivation of other cereals)
5. Level of technology is low for traditional wet rice cultivation.
-It is practised as a form of subsistence farming as well as commercial farming.
-Land: The size of the farm is generally small. Flat land with clayey soil is most ideal for such farming.
-Capital: It requires higher levels of capital than shifting cultivation. Machinery is used for ploughing and harvesting crops and canals need to be built to irrigate fields.
-Labour: Much labour is required and this comes from either family labour or hired labour. Much of the work such as planting and weeding is usually done by hand. Low walls known as bunds are built to flood the fields. Animals such as water buffaloes may be used to plough the land.
-High output per unit area.
-Main crop is wet rice.
• It is a form of commercial farming where crops are grown for sale.
• Plantations are found mainly in countries such as Malaysia and India which have tropical climates. These countries usually experience high annual temperatures and receive high annual rainfall.
• Plantation agriculture started in the colonial past in the 18th and early 19th centuries. Most plantations are now owned by local governments or big companies.
Characteristics
1. The crops are grown for sale so they are usually large. Sizes can vary from 40 hectares to over 1000 hectares.
2. It is capital intensive.
3. Modern technology is adopted in the production of crops. The use of high-yielding seeds (HYVs), chemical fertilizers and pesticides.
4. Many plantation crops are perennial crops, with an economic life that extends over many years. Egs such as rubber, oil palm, tea, coffee and cocoa.
5. They are usually grown in neat rows.
-It is a form of commercial farming. Some crops are sold as raw materials to manufacturing industries.
-Land: Plantations take up large areas of land.
-Capital: A large amount of capital is invested in the infrastructure, fertilisers and pesticides.
-Labour: A very large labour force is required to tend to the crops and work in processing factories.
-Total output is high but its output per unit area is usually low because a plantation covers a wide area of land.
-Usually one main crop is grown. Examples include rubber, coffee, tea, bananas, sugar cane, oil palm, cocoa and tobacco.
• High-tech farming uses modern machinery and farm chemicals to obtain maximum yield from a given plot of land or a group of animals.
• It is practised in countries such as the United States of America, United Kingdom and Singapore.
Fruit and Vegetable Farming
• Crops in a hydroponics farm are cultivated in troughs filled with a nutrient solution and are grown under carefully controlled conditions with the help of computers.
• Plants in an aeroponics farm have their roots suspended in the air, with a nutrient solution being sprayed onto the roots. The air is cooled to simulate conditions found in temperate regions.
Animal Farming
• In cattle farming, cows are housed in special stalls, fed a special diet at exact times and milked by machines daily at appointed times.
• For egg farming in a modern chicken farm, hens are fed a special diet blended by computerised machines, and eggs are collected efficiently by conveyor belts.
Characteristics
1.Large capital is required.
2. Highly skilled labour to carry out research and development to increase crop yield and improve the quality of the output.
3. Less dependent on physical factors. Farmers use soilless culture, tissue culture and the use of computers to automate farm activities.
4. Farms are Intensive to maximize productivity
5. Usually located near large urban centres /cities
-It is a type of commercial farming and is important in countries with high population density and limited land area, as it enables maximum output on a small plot of land.
-Land: Small land area is required as crops are grown closer together.
-Capital: Huge investments are required due to the use of the latest technology, farm chemicals and cost of research and development.
-Labour: The need for human labour is reduced as high-tech farms are highly mechanised.
-The output per unit area is higher than traditional farming.
-Food such as fruits, vegetables, dairy products and eggs are produced.

2. Higher levels of income
-people are able to afford better nutrition and do not suffer from food shortages
3. Better medical and health care
-improve the survival rate of babies, redicing infant mortality rate
-less prone to falling sick
-less prone to contracting diseases due to better hygiene and clean living conditions
Factors leading to Low Birth Rate:
1. Late marriages
-couples tend to have fewer children because they have fewer years to have babies
2. Fewer marriages
-result in fewer families and fall in birth rate
3. Preference to have smaller families
-due to increase in cost of living and raising kids
-and difficulties in balancing work and family life
Consequences of Low rate of population growth
1. Ageing population
-increase in burden on the working population as there are mroe elderly joining the workforce and fewer youths
2. Higher taxes
-each working person has to pay more tax to fund public amenities and projects
3. Smaller talent pool
-fewer people to choose from to lead and serve the country
Actions to manage Low rate of population growth
1. Encouraging marriange and childbearing
-gives incentives in the form of tax rebates to couples who have more children (e.g. Singapore)
2. Need of an ageing population
-building special facilities for elderly and encouraging their families to care for them
3. Special facilities
-specialised hospitals to treat illnesses associated with the elderly and homes catering to them
4. Keep elderly healthy and active
-opening exercise classes and courses for lifelong learning at community centres
5. Extend working life
-to reduce the burden on the working population
-to raise retirement age
6. Encourage financial planning
-early planning to ensure people have enough financial resources when they retire to meet their life goals
High rate of population growth
Causes: -Low Death Rate - High Birth Rate
Factors leading to Low Death Rate:
1. Better medical and health care
-improve the survival rate of babies, reducing infant mortality rate
-less prone to falling sick
-less prone to contracting diseases due to better hygiene and clean living conditions
Factors leading to High Birth Rate:
1. Lack of family planning
-common in less developed countries
-less educated and unaware of family planning methods
2. Early marriages
-increase childbearing years for the women
3. Preference for sons
-parents have children till they succeed in having sons (e.g. China and India)
4. Need for farm labour
-common in less developed countries
-large families to provide more hands to work in the fields
Consequences of High rate of population growth
1. Demand for resourses
-food and water increases with more people
-less developed countries often suffer from the shortage of food due to insufficient production of food
2. Higher demand for housing
-demand for housing increases with more people
-inadequate housing for growing populations in cities of less developed countries
3. Lack of proper housing
-squatter settlements and make-shift houses have sprouted around the outskirts of cities of less developed countries
4. Rapid population growth
-leading to intense competition for limited number of jobs
5. Environmental problems
-lack of proper waste disposal services to deal with the waste produced by the people
-waste left unattended to can lead to pollution of the environment and the deterrioration of living conditions
Actions to control a High rate of population growth
1. Education
-proper family planning methods can teach couples to control the size of their families
2. Incentives and penalties
-tax subsidies may be given to couples who have fewer children while those who have more may be punished with higher taxes
EXAMPLE: CHINA'S 'ONE CHILD POLICY'
fine couples who have more than one child while providing education and housing subsidies to those who complied with the policy

Yesterday, I went to the newest expressway in Singapore, the KPE (Kallang-Paya Lebar Expressway). It's a underground tunnel connecting from the ECP (East Coast Parkway), crossing under Pelton Canal, Paya Lebar Road, Airport Road, emerging at ground level at Defu Lane, and joining TPE (Tampines Expressway) at Lorong Halus. This major project was planned way before I was born, in the 1960s, and cost S$1.8 billion! The design is nice, safety precautions are also well taken care of, and the ventilation system is ultra cool! Well, I think LTA(Land Transport Authority) had done a remarkable job in conservation for the environment, by land preservation, preserved field truck, minimized surface disruption, and reducing noise and dust pollution. More picture in the tunnel: For more information on KPE, check out: http://www.kpeunderground.sg/ And if you're interested, you can join LTA for the Family Day cum Walk-a-Jog at KPE on Sunday, 21 October, 7.30am to 2pm. You'll get to run on the tracks before the vehicles do!!!
KPE pre-opening exhibitionY
Just look at this video on how we've all enjoyed ourselves when all 3 of the Saccardo nozzled were switched on:
Guess what is the speed of air through that air-sock-like thing? Believe it or not, it's 30metres/sec!
The KPE Tunnel Discovery begins...
Travelling through the completed part of the underground tunnel...
Check out the emergency cabinet! It has everything you need during an emergency!
Travelling up the emergency escape staircase...
Coming out of the escape staircase... so we were under this place all this while!
Gosh, we were captured by the surveilance camera in the tunnel! (twist to the camera... michelle!)
That's the Saccardo nozzle. Only 1 at full blast.
