Impact of Coal Mining on LULC Change Using Geospatial AI

Rapid economic growth and industrialization have significantly impacted the environment, especially in resource-extractive regions like the Jharia Coalfield in Dhanbad, Jharkhand, India. This study uses an integrated approach combining remote sensing, GIS, and geospatial artificial intelligence (GeoAI) to analyze Land Use/Land Cover (LULC) changes from 1992 to 2014. Supervised classification using the Maximum Likelihood algorithm was applied to enhance spatial accuracy. The results reveal substantial spatiotemporal shifts: coal locations, dense forests, water bodies, and barren lands declined, while vegetation regrowth and residential areas increased. This change analysis identifies high-risk zones and degraded landscapes resulting from unregulated mining. A net loss of over 38% in forest and water areas was recorded, with significant expansion in coal zones and settlements. Remote sensing and GIS proved effective in mapping land degradation. The findings highlight the urgent need for sustainable land use policies and support the development of a long-term environmental management plan for the Jharia Coalfield.
The field of photocatalysis merges light-driven chemical reactions with green chemistry to produce sustainable and efficient transformations in organic synthesis. It enables reactions that minimize waste and energy consumption while enhancing product selectivity. Photocatalysis for Organic Synthesis: Principles and Applications discusses the mechanisms, catalysts, and technological advances in photocatalytic organic transformations. It explains how visible-light catalysts function and explores real-world industrial and pharmaceutical applications. The book provides practical examples of photoredox reactions and scaling techniques. Each chapter integrates theoretical aspects with experimental methodologies, making it ideal for students and researchers in chemical sciences.
Synthetic biology integrates biology and chemistry to design and construct new biological systems and pathways that perform desired functions. It redefines the boundaries of life sciences by enabling the synthesis of novel biomolecules and artificial organisms. Synthetic Biology and Chemistry introduces the fundamental concepts, techniques, and applications of this interdisciplinary field. The book highlights DNA assembly methods, metabolic engineering, and biotechnological innovations. It also explores ethical and safety concerns surrounding synthetic systems. Through real-world examples and detailed illustrations, readers gain a deep understanding of how synthetic biology shapes biotechnology, healthcare, and material science.
Diversification of Agriculture in District Lakhimpur Khire of U.P

Indian economy is predominantly rural and agrarian with agriculture employing about 31 per cent of the work force. Diversification is a technique that reduces risk by allocating investments among various financial instruments, industries and other categories. It aims to maximise return by investing in different areas that would each react differently to the same event.Agriculture and allied activities constitute the single largest contributor to the Gross Domestic Product (GDP), accounting for almost 33% of the total. They are vital to the national well-being as, besides providing the basic needs of the society and the raw materials for some of the important segments of Indian industry, they provide livelihood for almost two thirds of the work force. The share of the agricultural products in the total export earnings, both in primary and processed forms, is very significant. Over the last four decades, agriculture has made important strides in our country.
