Latest Class 8th Geography NCERT Notes, NCERT Question Solutions and Extra Q & A
1. Resources
This chapter introduces the fundamental concept of resources, defining them as anything in our environment that has utility and value to satisfy human needs. Resources are broadly classified into three categories: Natural resources, which are drawn directly from nature without much modification (e.g., air, water, forests, minerals); Human-made resources, which are created by humans using natural resources (e.g., buildings, bridges, machinery); and Human resources, which refers to people themselves, with their knowledge, skills, and health. The chapter underscores the critical need for resource management. It introduces two vital concepts: resource conservation, which means using resources carefully and giving them time to get renewed, and sustainable development, the principle of carefully utilizing resources so that besides meeting the requirements of the present, it also takes care of future generations. This balanced approach is essential for the progress of any nation, including a resource-rich country like India.
2. Land, Soil, Water, Natural Vegetation And Wildlife Resources
This chapter provides a detailed exploration of the planet's most vital natural resources. It discusses land use for various purposes like agriculture, forestry, and urbanisation, and addresses the problem of land degradation. It explains that soil is the thin top layer of the earth's crust, crucial for agriculture, and discusses the factors affecting its formation. The chapter emphasizes the importance of water, describing the water cycle and the growing problem of water scarcity. It then explores the interconnectedness of natural vegetation and wildlife, which together form our ecosystems. The central theme is the conservation of these precious resources. Methods like afforestation, land reclamation, contour ploughing, rainwater harvesting, and the establishment of protected areas such as national parks and wildlife sanctuaries are highlighted as crucial measures to maintain ecological balance. This is especially important for India, a megadiverse country with rich flora and fauna that requires diligent conservation efforts.
3. Agriculture
This chapter focuses on agriculture, a key primary economic activity that involves the science and art of cultivating the soil, growing crops, and raising livestock. It introduces the concept of a farm system, with inputs (seeds, fertilisers), processes (ploughing, sowing), and outputs (crops). The chapter classifies agriculture into two main types: Subsistence farming, practiced to meet the needs of the farmer's family, and Commercial farming, where crops are grown and animals are reared for sale in the market. It discusses major food and cash crops like rice, wheat, millets, maize, cotton, jute, coffee, and tea, outlining the climatic conditions necessary for their cultivation. A significant focus is given to agricultural development, particularly the Green Revolution in India, a landmark initiative that used High-Yielding Variety (HYV) seeds, modern irrigation, and fertilisers to dramatically increase the production of food grains and ensure food security for the nation's vast population.
4. Industries
This chapter introduces industries as a secondary economic activity focused on the processing of raw materials and manufacturing of goods. It presents a detailed classification of industries based on different criteria: on the basis of raw materials (agro-based, mineral-based, marine-based, forest-based); on the basis of size (small-scale and large-scale industries); and on the basis of ownership (private sector, public sector, joint sector, and cooperative sector). The chapter analyses the key geographical and economic factors that influence the location of industries, such as the availability of raw materials, labour, capital, power, transport, and market access. It provides an overview of major global industries, including the Iron and Steel industry (the backbone of modern industry), the Textile industry, and the rapidly growing Information Technology (IT) industry, highlighting important industrial clusters like the Mumbai-Pune industrial region in India as engines of economic growth.
5. Human Resources
This chapter establishes that human resources—the people—are a nation's greatest asset, as it is their skills, knowledge, and health that transform other resources into valuable assets. It delves into the study of population dynamics, explaining key demographic concepts. These include the distribution of population, which is uneven across the world and influenced by geographical and socio-economic factors; population density, the number of people living in a unit area; and population change, governed by birth rates, death rates, and migration. The chapter also explores population composition, which refers to the structure of the population in terms of age, sex, literacy levels, and occupation, often visualized through a population pyramid. With its focus on India's large population, the chapter highlights that a healthy, educated, and skilled populace can become a powerful human resource, driving national development and economic progress, a concept known as the "demographic dividend".
