Question : Assertion: Land degradation is a significant environmental challenge that hinders sustainable development.
Reason: Land degradation reduces agricultural productivity, biodiversity, and ecosystem services.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.
Option 4: Assertion is incorrect, but the reason is correct.
Correct Answer: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
The assertion states that land degradation is a significant environmental challenge that hinders sustainable development. The reason provided is that land degradation reduces agricultural productivity, biodiversity, and ecosystem services.
Land degradation refers to the deterioration of land quality, typically caused by human activities such as deforestation, overgrazing, unsustainable agricultural practices, and urbanization. It is a significant environmental challenge because it can lead to the loss of fertile soil, reduced water availability, increased erosion, and decreased vegetation cover. Land degradation can negatively impact ecosystems, biodiversity, and human well-being.
The reason provided correctly explains the negative impacts of land degradation. When land is degraded, it loses its ability to support productive agricultural systems, leading to reduced agricultural productivity and food security. Land degradation also results in the loss of habitat and biodiversity, as many species depend on healthy ecosystems for their survival. Additionally, land degradation can disrupt ecosystem services such as water purification, soil fertility, and climate regulation, further impacting human societies and the environment. Therefore, both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.
Question : Assertion: Forest conservation plays a crucial role in sustainable development as forests provide numerous ecosystem services, including carbon sequestration and biodiversity preservation.
Reason: Deforestation leads to environmental degradation, loss of biodiversity, and contributes to climate change.
Question : Assertion: Biodiversity conservation is crucial for sustainable development.
Reason: Biodiversity provides essential ecosystem services and supports human well-being.
Question : Assertion: Ecosystem restoration is vital for sustainable development as it helps to revive degraded ecosystems and enhance their capacity to provide essential services.
Reason: Degraded ecosystems are less resilient and less capable of supporting biodiversity and providing ecosystem services.
Question : Assertion: Forest conservation is essential for maintaining ecological balance and supporting sustainable development.
Reason: Forests provide numerous ecosystem services, such as carbon sequestration, water regulation, and biodiversity conservation.
Question : Assertion: Biodiversity conservation is essential for sustainable development as it ensures the stability and resilience of ecosystems.
Reason: Biodiversity loss can disrupt ecosystem functions, negatively impacting human well-being and the environment.
