7. Locational advantages of the site Environment Society Economy

8. If the land is used for farming … Suggestion one: aloe Reason: They can be grown in sandy soil. There is a demand for aloe in Hong Kong.

9. Suggestion two: Tea Reasons: Tea can be grown in hill slope Profitable

10. Alternative use of the land Suggestion: 假日農莊 Reasons: Recreational use Profitable

11. Appropriate Eco-farming techniques Crop Rotation Organic Farming ( natural fertilizer, no pesticides) Diversification

12. How do they benefit the ecosystem? Maintain nutrient cycle Larger the biodiversity Increase the stability

13. Benefits to society Educate our next generation Raise public awareness

14. Benefits to economy Increase economical efficiency Increase output

15. Disadvantages Higher cost use of non renewable resources for replenishment cost of new irrigation system. Exotic species New species may not be able to adopt the environment. May dominant the ecosystem. Food chain affected.
