Challenges of Poor Environmental Impact Assessments in Mining Projects: A Critical Analysis for India Introduction Mining plays a pivotal role in India's economy, contributing significantly to Gross Domestic Product (GDP) and employment. However, the environmental impacts associated with mining activities cannot be overlooked. To mitigate these impacts, regulatory frameworks require thorough Environmental Impact Assessments (EIAs) before granting environmental clearance for mining projects. Despite these regulations, the effectiveness of EIAs in India has been questioned, leading to delays and controversies in the clearance process. It is important to collaborate and prioritize the integrity of the EIA process for the long-term benefit of the environment, mining industry growth and communities affected by mining activities. This article critically examines the challenges posed by poor EIAs in Indian mining projects. Understanding Environmental Impact Assessments (EIAs) Env...

Gondwana coal deposits of India: Fueling growth Indian Gondwana Coal Basins Introduction The Indian Gondwana coal deposits are primarily found in the eastern and central parts of India, dating back to the Permian and Triassic periods. They are spread across several states in central and eastern India, primarily in the Damodar Valley Basin (Jharkhand and West Bengal), Mahanadi Basin (Odisha), Son-Mahanadi Basin (Chhattisgarh), Godavari Valley Basin (Telangana and Maharashtra), and Wardha Valley Basin (Maharashtra). These coal deposits are stratigraphically classified into several formations, including the Talchir, Barakar, Raniganj, and Kamthi formations. The coal-bearing strata are typically interbedded with sandstones, shales, and conglomerates, representing fluvial and lacustrine environments. These formations hold significant economic importance as they contain vast reserves of coal, contributing significantly to India's energy and growth needs. Geological Setting The ...
