Explanations:The forest cover of a state is a significant environmental indicator that reflects the extent of land covered by forests. This metric is essential for assessing the ecological health, biodiversity, and sustainability of a region. The Indian Forest Report, published by the Ministry of Environment, Forest and Climate Change, provides detailed information on the forest cover across all states and union territories in India.
In the context of Tamil Nadu, the forest cover percentage is a critical piece of data for understanding the state's environmental status. The 2017 Indian Forest Report is a comprehensive document that includes various metrics such as forest cover, tree cover, and green cover. The specific data for Tamil Nadu's forest cover in 2017 is 20.21%, which is the correct answer to the question.
It is important to note that the forest cover percentage can vary from year to year due to various factors such as afforestation efforts, deforestation, and natural growth. Therefore, it is crucial to refer to the most recent and official reports for accurate and up-to-date information. The Indian Forest Report is a reliable source for such data and is widely used in competitive examinations and environmental studies.
Understanding the forest cover of a state is not only important for environmental assessments but also for policy-making, conservation efforts, and sustainable development initiatives. The data helps in planning and implementing strategies to enhance forest cover and protect biodiversity. For students preparing for competitive exams, it is essential to be familiar with such state-specific environmental statistics to perform well in general knowledge and environmental science sections.
