Intensification of food production<br /><ul><li>Make full use and increase the productivity of a land</li></ul>Productivity<br /><ul><li>Amount of food / amount of resources used to produce food</li></li></ul><li>Factors affecting productivity<br />Physical factors<br />Relief<br />Soil<br />Climate<br />
Relief<br />The difference between the highest and lowest elevations in an area. <br />Refers to physical height and slope of the land<br />Gentle/ flat relief:_____________<br />Facilitates movement and transportation.<br />
Soil<br />Productivity depends on fertility of soil<br />Requires right amount of water, sunlight, air and nutrients<br />Where can you find fertile soils? <br />_____________________________<br />
Climate<br />Refers to atmospheric conditions of a specific place over a considerable period of time (30-35 years)<br />High temperature & rainfall :___________<br />
Social factors<br />Land fragmentation<br />= land is divided into smaller plots<br />= Resultant plots will eventually become small over time<br />
Social factors<br />Land tenure<br />A land which is owned by an individual/government, who is said to "hold" the land.<br />Farmers must pay a sum of money or give a portion of their crops to get the right to live on, work and use the land.<br />Little motivation for the farmers.<br />
Political factors<br />Government policies<br /> Government has a final say on how resources are to be used to bring greater development in the country.<br />
New Food Self-Sufficiency Policy Could Revive Farming in Singapore<br /> Singapore. Wong KokFah, one of Singapore’s last remaining farmers, can finally see a future for his vegetable business after 30 years of back-breaking work. Plans by the industrialized city-state to set aside more land for farming to boost food security have given him hope that the fourth generation of the Wong family can continue the business started by his grandfather. “In the past, my thinking was I’ll do it for as long as I can,” said Wong, a stocky 48-year-old with a prematurely aged face. “It’s difficult for the next generation to continue in this business if there’s no help from the government,” he said. “How could I make any plans for my business when I could see no future in it?<br />
Agricultural Types – High-Tech Farming<br /><ul><li> 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.</li></ul>Fruit and Vegetable Farming<br /><ul><li> 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.</li></li></ul><li>Agricultural Types – High-Tech Farming<br />Animal Farming<br /><ul><li> 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.</li></ul>Milking of cows using special machines.<br />Eggs are collected via conveyor belts, saving both time and effort.<br />
Technological factors<br />Use of modern machines and farming methods to have greater control over the physical limitations<br />The Green Revolution<br />Due to rapid population growth, a need to increase food production<br />Incorporate modern technology to overcome food shortage and help subsistence farmers in LDCs to increase their income.<br />
High yielding varieties<br />Improved strains of rice, wheat and other cereals<br />Developed by cross breeding<br />HYVs have special traits: pest resistance and shorter growth period<br />E.g: IR58 = 100 days<br /> IR8 =130 days<br />
Modern irrigation methods<br />Irrigation= practice of supplying water to the land through artificial means<br />Benefits<br /><ul><li>Control the amount of water supplied to the crop
Ensure that crop receive enough water at all seasons</li></li></ul><li>Use of chemicals<br />Fertilisers<br /><ul><li>Substances added to provide nutrients for healthy growth</li></ul>Pesticides<br />- Toxic chemicals used to remove pests from affecting the crops<br />Herbicides<br />- Herbicides is used to remove the weeds because removing by hand is time consuming and laborious<br />
New method of fish farming<br />Aims to protect marine life and ensure sufficient seafood for present and future generations<br />How is it done?<br />Rear fish in tanks or enclosed areas under special conditions that promote growth<br />The Blue Revolution<br />
