Study Notes

Human Environment Interactions: The Tropical and the Subtropical Region

Renuka's Experience: Renuka was excited by the return of her uncle, a wildlife photographer, after several months. Her interest in nature and wildlife began early, sparked by her uncle's introduction to nature books.
Diversity of People: Pictures displayed people from various regions, including deserts, frozen lands, and rainforests. These people, though looking different, share common life needs: food, clothing, and shelter.
Life in the Amazon Basin: People in the Amazon basin are closely connected to nature. Children learn to care for nature, catch fish, and gather materials from the forests early in life.
Amazon Basin Geography: The Amazon basin is located near the equator and flows from the mountains to the Atlantic Ocean. Tributaries join the Amazon River to form a large basin covering parts of South American countries.
Amazon Basin Climate: The region has a hot and humid climate, with almost daily rainfall. The high humidity and rainfall create thick, dense rainforests.
Rainforest Flora and Fauna: Orchids and bromeliads are common. Birds like toucans and macaws have colourful plumage. Animals like monkeys, sloths, and reptiles are also found.
People of the Rainforest: People in the rainforest grow crops like tapioca, pineapple, sweet potatoes and also slash and burn agriculture: cutting and burning vegetation for crop growing areas. Women are responsible for some farming tasks, while men often hunt and fish.
Ganga-Brahmaputra Basin: This basin in the Indian subcontinent is formed by the tributaries of the Ganga and Brahmaputra rivers. It’s location is between 10°N to 30°N and includes the Ghaghra, Son, Chambal, Gandak, and Kosi rivers as tributaries. Agriculture is a major activity.
Himalayas & Sundarbans: The Himalayas and the Sundarbans delta are key features of this basin. The area experiences monsoon seasons from mid-June to mid-September.
Population Density: The population density varies based on topography, with higher densities in the plains—areas with suitable land for agriculture and sufficient water supply.
Important Cities: Major cities such as Allahabad, Kanpur, Varanasi, Lucknow, Patna, and Kolkata are located along the Ganga River.
Transportation: Waterways, roadways, railways, and airports are important means of transport.
Environmental Concerns: The gradual destruction of rainforest, impacts from industrial and urban waste, and deforestation are environmental issues affecting the two river systems.
