The given question pertains to land degradation and includes two statements. Let's analyze each statement separately to determine their correctness.

1. The extent of soil degradation by agricultural mismanagement is greater than the Industry and urbanization.
This statement states that soil degradation caused by agricultural mismanagement is more significant than that caused by industry and urbanization. To evaluate the accuracy of this statement, we need to consider the impact of each factor on land degradation.

Agricultural Mismanagement:
- Unsustainable farming practices such as excessive use of chemical fertilizers and pesticides, overgrazing, deforestation, and improper irrigation can lead to soil erosion, nutrient depletion, and loss of soil fertility.
- Improper land management techniques, such as lack of crop rotation and inadequate soil conservation measures, can exacerbate soil degradation.

Industry and Urbanization:
- Industrial activities contribute to land degradation through pollution, including chemical spills and release of toxic substances into the environment.
- Urbanization leads to the conversion of agricultural land into built-up areas, resulting in soil sealing, loss of biodiversity, and disruption of natural ecosystems.

Considering the above points, it can be concluded that both agricultural mismanagement and industry/urbanization contribute significantly to land degradation. However, it is challenging to quantify the extent of degradation caused by each factor accurately. Therefore, statement 1 cannot be definitively proven or disproven.

2. Under the Bonn Challenge for restoration of degraded land, India has pledged the highest percentage of total area for restoration in the Asia-Pacific region.
The Bonn Challenge is a global effort to restore degraded and deforested land to address climate change, biodiversity loss, and land degradation. India's commitment to the Bonn Challenge is indeed significant. To determine the correctness of this statement, let's examine India's pledge and its position in the Asia-Pacific region.

India's Pledge:
- India has pledged to restore 26 million hectares (Mha) of degraded land by 2030, as part of its commitment to the Bonn Challenge.
- This pledge accounts for approximately 10% of the global target set by the Bonn Challenge, making India one of the leading countries in terms of land restoration efforts.

Asia-Pacific Region:
- The Asia-Pacific region faces significant land degradation challenges due to factors such as deforestation, unsustainable land use practices, and rapid urbanization.
- Several countries in the region, including China, Mongolia, and Indonesia, have made substantial pledges to restore degraded land under the Bonn Challenge.

Considering the above information, it can be concluded that statement 2 is correct. India has indeed pledged the highest percentage of total area for restoration in the Asia-Pacific region under the Bonn Challenge.

In summary:
- Statement 1 cannot be definitively proven or disproven as both agricultural mismanagement and industry/urbanization contribute significantly to land degradation.
- Statement 2 is correct as India has pledged the highest percentage of total area for restoration in the Asia-Pacific region as part of its commitment to the Bonn Challenge.
