Causes: logging, agriculture, urbanisation：練習問題

Shifting cultivation, also known as slash-and-burn agriculture, is a traditional practice in some tropical rainforest regions. What is its primary long-term impact on the rainforest ecosystem when practiced by a growing population?

The practice of 'debt-for-nature' swaps aims to reduce deforestation primarily by addressing which underlying economic factor driving large-scale resource exploitation in developing tropical nations?

Commercial logging in rainforests involves the creation of logging roads to transport timber. Which of the following is the most significant long-term ecological consequence of these roads on biodiversity?

Which of the following is a primary human factor contributing to rapid urbanisation?

When tropical rainforest is cleared and converted to large fields for crops like soybeans or oil palm, why does the newly exposed topsoil become highly vulnerable to nutrient loss and erosion, especially in regions with high rainfall?

Besides the immediate removal of trees, what secondary environmental problem is often triggered or intensified by the construction of access roads for commercial logging in remote rainforest areas?

Explain one direct way in which rapid urbanisation contributes to the loss of tropical rainforest cover in adjacent areas.

Explain how the combined pressure of logging, agriculture, and urbanisation often creates a self-reinforcing cycle of deforestation in tropical rainforest regions, making conservation particularly challenging.

Agriculture is a major driver of deforestation in tropical rainforest regions, particularly the shift towards commercial practices.

Compare and contrast the environmental impacts associated with traditional indigenous practices (like sustainable shifting cultivation) versus modern large-scale commercial activities (like monoculture plantations) on the rainforest environment, focusing on the scale and permanence of the disturbance.

The conversion of tropical rainforests due to activities like urbanisation and logging has global implications.

(a) Explain the mechanism by which the large-scale removal of rainforest cover affects the global energy balance and contributes to climate change. (3 points)

(b) Discuss one major potential loss for human society worldwide resulting from the destruction of the unique biodiversity pool found in tropical rainforests (e.g., in terms of medicine or ecosystem services). (3 points)
