This document discusses factors that affect the intensity and productivity of food production. It outlines physical factors like relief, soil, and climate that influence where different crops can be grown. It also discusses social factors like land fragmentation and land tenure. Technological factors that can increase productivity through high-tech farming are also outlined, including the use of machinery, fertilizers, pesticides, herbicides, and new irrigation and fish farming methods. The document provides examples of how these factors can maximize food production from available resources.

1. Intensity of food production

4. Relief The difference between the highest and lowest elevations in an area. Refers to physical height and slope of the land Gentle/ flat relief:_____________ Facilitates movement and transportation.

5. Soil Productivity depends on fertility of soil Requires right amount of water, sunlight, air and nutrients Where can you find fertile soils? _____________________________

6. Climate Refers to atmospheric conditions of a specific place over a considerable period of time (30-35 years) High temperature & rainfall :___________

7. Social factors Land fragmentation = land is divided into smaller plots = Resultant plots will eventually become small over time

8. Social factors Land tenure A land which is owned by an individual/government, who is said to "hold" the land. 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. Little motivation for the farmers.

9. Political factors Government policies Government has a final say on how resources are to be used to bring greater development in the country.

10. New Food Self-Sufficiency Policy Could Revive Farming in Singapore 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?

14. 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.Milking of cows using special machines. Eggs are collected via conveyor belts, saving both time and effort.

15. Agricultural Types – High-Tech Farming

16. Technological factors Use of modern machines and farming methods to have greater control over the physical limitations The Green Revolution Due to rapid population growth, a need to increase food production Incorporate modern technology to overcome food shortage and help subsistence farmers in LDCs to increase their income.

17. High yielding varieties Improved strains of rice, wheat and other cereals Developed by cross breeding HYVs have special traits: pest resistance and shorter growth period E.g: IR58 = 100 days IR8 =130 days

20. New method of fish farming Aims to protect marine life and ensure sufficient seafood for present and future generations How is it done? Rear fish in tanks or enclosed areas under special conditions that promote growth The Blue Revolution
