Comparative perspectives with conventional forestry, global case studies, challenges, limitations, and future prospects are also addressed. The approach emphasizes maintaining forest structure, regeneration, biodiversity, and ecosystem functions while allowing appropriate harvesting and resource utilization.

This chapter introduces the scientific principles underlying the structure, properties, processing, preservation, and utilization of wood. It examines the anatomical organization and chemical composition of wood and explains relationships between structure and important physical and mechanical properties. The chapter also discusses moisture interaction, dimensional behaviour, mechanical performance, durability, seasoning, preservation, and wood-processing technologies. Engineered wood products and modern approaches to wood utilization are considered as important components of forest-product development. Together, these topics provide an understanding of wood as an important renewable material and its efficient, durable, and sustainable utilization.

This chapter introduces the scientific, biological, chemical, and economic importance of medicinal and aromatic plants associated with forest and allied systems. It examines their classification and diversity, chemical constituents, harvesting practices, processing, value addition, and extraction techniques. The chapter highlights the potential of these plants as valuable biological resources and explores approaches for their productive utilization. Sustainable harvesting, appropriate processing, and value addition are important for improving their economic potential while supporting conservation and responsible management of plant resources.

This chapter introduces non-timber forest products (NTFPs) as important biological resources supporting rural livelihoods, local economies, and forest-dependent communities. It examines the definition, scope, classification, diversity, and importance of NTFPs in India. The chapter also discusses value chains, market dynamics, trade, sectoral challenges, and constraints affecting their sustainable utilization. Particular attention is given to conservation, policy frameworks, community livelihoods, and a case study of NTFPs in Maharashtra. The chapter emphasizes the need to balance resource utilization with sustainable forest management and biodiversity conservation.

This chapter introduces the integration of Geographic Information Systems (GIS), remote sensing, and artificial intelligence (AI) for modern forest monitoring and management. It explains how remote sensing provides spatially continuous information, GIS functions as a spatial database and decision-support environment, and AI and machine learning enable prediction and pattern recognition. Applications include forest inventory, carbon estimation, biodiversity assessment, forest-fire detection, insect monitoring, and disturbance mapping. The chapter also examines GeoAI, smart forestry, emerging technologies, data challenges, and future opportunities such as cloud-based geospatial platforms and explainable AI.
