Open Ended

Selective logging is effective in conserving the TRF because...

Selective logging is effective because...

• the affected area is smaller

• Only mature trees of economic value are selected

• so non-economic species are protected

• this allows the regeneration of forests

Open Ended

Selective logging is NOT effective in conserving the TRF because...

Selective logging is NOT effective because...

• Financial ability

• Level of technology

• Level of monitoring

• Other supporting measures, e.g. cutting lianas and climbers that tie up the trees

Poll

Do you think the proposal is feasible?

• Yes

• No

Open Ended

It is rather not feasible because ....

It is rather not feasible because ...

• any negative socio-economic impacts if abandon cattle ranch? What human activity can generate more economic returns? Will it affect job opportunities and income of farmers?

• is it easy to regeneration a secondary forest from the abandoned site? What are some of the considerations? time? cost? species?

Past paper DBQ

2013

​The total reforested area between 1991 and 2011 was 56 560 sq.km.

​

With reference to Figure 4a, evaluate the effectiveness of reforestation in conserving the forest area in Amazon Basin. (4 marks)

Open Ended

What is reforestation?

• Reforestation is done by planting a mix local tree species and allowing the land to regrow into a secondary forest.

Suggested answer

Poll

Do you think reforestation is effective in conserving the forest area?

• Yes

• No

Open Ended

​The total reforested area between 1991 and 2011 was 56 560 sq.km.

Why reforestation is not effective? Use Figure 4a to help explain the answer.

• Reforestation is done by planting a mix of local tree species and allowing the land to regrow into a secondary forest.

Suggested answer

• I think it is not effective in conserving forest area because the reforested area as compared with the loss of rainforest area is much smaller.

Open Ended

Why reforestation is not effective? Any other reasons?

• Reforestation is done by planting a mix of local tree species and allowing the land to regrow into a secondary forest.

Suggested answer

• I think it is not effective in conserving forest area because the reforested area as compared with the loss of rainforest area is much smaller.

• ​What's more, there is only limited species suitable for planting. introducing exotic species may disrupt the ecosystem.

• Trees take a very long time to regenerate.

• The cost of reforestation is high. Most of the rainforest countries are LDCs. They are poor and lack of capital to carry out these conservation projects. Besides, the revenue generated is very small.

• The effectiveness is also affected by the low education level of the people which may lead to poor monitoring and enforcement.

Open Ended

Why still carry out reforestation even it is not effective in conserving the forest areas?

It is effective since

• it helps to slow down the loss of rainforests.

• Reforestation is done by planting a mix of local tree species and allowing the land to regrow into a secondary forest.

Suggested answer

• I think it is not effective in conserving forest area because the reforested area as compared with the loss of rainforest area is much smaller.

• ​What's more, there is only limited species suitable for planting. introducing exotic species may disrupt the ecosystem.

• Trees take a very long time to regenerate.

• The effectiveness is also affected by the low education level of the people which may lead to poor monitoring and enforcement.

• Thus, although reforestation helps to slow down the loss of rainforest area, it is not effective in conserving forest area.

*What is your stance? (i.e. whether it is effective / suitable / preferrable / feasible or not)

*What is the measure about? (describe briefly)

*Why is it effective / suitable / preferrable / feasible?

*Under what circumstances will it be ineffective / not suitable / not preferrable / not feasible (i.e. its limitations)?

*Any information / data from the source to support your argument?

*Is your discussion too general? Is it related to the case / situation mentioned in the question? Have you referred to the unique characteristics and features of the measure?

​Structure in responding to discussion questions

DBQ

• Evaluate the effectiveness of: reforestation (2013); rainforest adoption (2014); selective logging (2016)

• Discuss whether: limiting the area of plantation and rainforest conservation in the world (2018)

• Feasibility of abandon cattle ranching, restoring rainforests and developing ecotourism (2020)

● Discuss if certain strategy (intensive vs limited human intervention) is more preferrable in restoring a cleared tropical rainforest area. (2022)

Essay

• Evaluate the effectiveness of: national park (2012);

• Discuss: the role of MDC in limiting the area of plantation and rainforest conservation in the world (2015)
• Discuss whether the development of agroforestry can make use of the developed TRF in a more sustainable way (2023)

Past paper DBQ

2018

Refer to Figure 4a and Table 4c. Discuss whether limiting the area of oil palm plantations in Indonesia may help conserve tropical rainforests in the world.

Poll

Do you think limiting the area of oil palm plantations in Indonesia may help conserve tropical rainforests in the world?

• Yes

• No

Open Ended

Briefly tell what oil palm plantation is. [1 mark]

• Oil palm plantation in Indonesia is a kind of commercial agricultural activity which carried out by large agribusiness.

Suggested answer

• Refer to Figure 4a and Table 4c. Discuss whether limiting the area of oil palm plantations in Indonesia may help conserve tropical rainforests in the world.

2 Discussion points

Open Ended

It may not help conserve TRFs in the world because ...

[use Figure 4a to help explain your answer]

• Oil palm plantation in Indonesia is a kind of commercial agricultural activity which carried out by large agribusiness.

Suggested answer

• It may not help conserve rainforests in the world because

  • limiting plantation in Indonesia may increase the rate of deforestation in other TRFs in the world.

  • limiting plantation in Indonesia cannot reduce the rate of deforestation in other TRFs in the world

Open Ended

Is plantation the only human activities causes deforestation? What are other human activities which contribute even more destructions to TRFs?

• Oil palm plantation in Indonesia is a kind of commercial agricultural activity which carried out by large agribusiness.

Suggested answer

• It may not help conserve rainforests in the world because

  • limiting plantation in Indonesia may increase the rate of deforestation in other TRFs in the world.

  • limiting plantation in Indonesia cannot reduce the rate of deforestation in other TRFs in the world

• ​Nevertheless, plantation is not the only human activity that causes deforestation. Cattle ranching and commercial logging contribute even more to the destruction of the rainforest. The development of these activities should also be control in order to conserve more rainforests.

Open Ended

Besides, it is hard to limit oil palm plantation in Indonesia.

[Why? Can you use Table 4C to further elaborate?]

e.g. describe the change in population. Then how does it relate to oil palm planation?

• Oil palm plantation in Indonesia is a kind of commercial agricultural activity which carried out by large agribusiness.

Suggested answer

• It may not help conserve rainforests in the world because

  • limiting plantation in Indonesia may increase the rate of deforestation in other TRFs in the world.

  • limiting plantation in Indonesia cannot reduce the rate of deforestation in other TRFs in the world

• ​Nevertheless, plantation is not the only human activity that causes deforestation. Cattle ranching and commercial logging contribute even more to the destruction of the rainforest. The development of these activities should also be control in order to conserve more rainforests.

• Besides, it is hard to limit oil palm plantation in Indonesia. From Table 4c, we can see that the population in Indonesia is increasing. This raises the demand of palm oil as it is the cheapest type of edible oil and can be used to produce a wide range of products. Limiting oil palm plantation may seriously affect the local supply of palm oil.

Open Ended

How about the export of palm oil?

Explain the impacts if oil palm plantation is limited.

• Oil palm plantation in Indonesia is a kind of commercial agricultural activity which carried out by large agribusiness.

Suggested answer

• It may not help conserve rainforests in the world because

  • limiting plantation in Indonesia may increase the rate of deforestation in other TRFs in the world.

  • limiting plantation in Indonesia cannot reduce the rate of deforestation in other TRFs in the world

• ​Nevertheless, plantation is not the only human activity that causes deforestation. Cattle ranching and commercial logging contribute even more to the destruction of the rainforest. The development of these activities should also be control in order to conserve more rainforests.

This raises the demand of palm oil as it is the cheapest type of edible oil and can be used to produce a wide range of products. Limiting oil palm plantation may seriously affect the local supply of palm oil.

• What's more, the export of palm oil is also increasing. That means Indonesia can earn more foreign exchange which helps to speed up economic development by exporting palm oil.

• Thus, palm oil is important to Indonesia in promoting economic development and living standard of the people.
