Urban planning and development

  1. Urban planning involves the design and regulation of land use and the built environment in cities and towns.
  2. Its goal is to create a functional, sustainable, and aesthetically pleasing urban environment.
  3. Urban planning focuses on infrastructure, transportation, housing, and public spaces.
  4. The concept emerged during the Industrial Revolution to address urban challenges such as overcrowding and sanitation.
  5. Comprehensive planning is a long-term approach that integrates multiple aspects of u

Types of settlements

  1. Settlements are places where people establish a permanent or temporary residence.
  2. They are classified based on their size, shape, pattern, and function.
  3. The two primary types of settlements are rural and urban.
  4. Rural settlements are small and closely associated with agriculture and natural resources.
  5. Urban settlements are larger, with complex economic activities and infrastructure.
  6. Rural Settlements:
    • Typically found in

Urbanization

  1. Urbanization refers to the process by which an increasing proportion of a population lives in urban areas.
  2. It is a key aspect of human geography and population studies.
  3. The shift from rural to urban areas is often linked to industrialization and economic development.
  4. Urban areas are characterized by higher population density and infrastructure development compared to rural areas.
  5. Urbanization typically occurs in phases, beginning with industrial

Demographic transition model

  1. The Demographic Transition Model (DTM) explains the transition of population growth through different stages of economic development.
  2. The model is divided into five stages, each representing changes in birth rates, death rates, and overall population growth.
  3. The DTM is based on historical population trends in industrialized countries.
  4. Stage 1: High Stationary Stage
    • Characterized by high birth rates and high death rates.
    • Population

Growth trends

  1. Population growth refers to the increase in the number of people over a specific period.
  2. Growth trends are influenced by birth rates, death rates, and migration patterns.
  3. Population growth can be positive (increase) or negative (decline).
  4. The global population has grown significantly since the Industrial Revolution.
  5. In the 20th century, the world experienced a population explosion, particularly after World War II.
  6. The global population reached

Population distribution and density

  1. Population distribution refers to the way people are spread across the Earth's surface.
  2. Population density is the number of people per unit area, usually expressed as people per square kilometer.
  3. Population distribution is influenced by physical, economic, social, and political factors.
  4. Areas with favorable climate, fertile soil, and water availability tend to have higher population densities.
  5. Regions like river valleys (e.g., the Nile and Ganges) are densely populated.

Soil types and distribution

  1. Soil is the uppermost layer of Earth's crust, supporting plant growth and containing organic and inorganic materials.
  2. The study of soil is known as pedology.
  3. Soil formation is influenced by factors such as parent material, climate, organisms, topography, and time.
  4. Soils are classified based on their texture, composition, and fertility.
  5. Globally, soils are categorized into major types such as alluvial soil, black soil, red soil, laterite soil, desert soil, and mountain soil

Biodiversity

  1. Biodiversity refers to the variety and variability of life on Earth, including genes, species, and ecosystems.
  2. It is essential for maintaining ecological balance and providing ecosystem services.
  3. Biodiversity is categorized into genetic diversity, species diversity, and ecosystem diversity.
  4. Genetic diversity refers to the variation in genes within a species, ensuring adaptability and survival.
  5. Species diversity indicates the variety of species in a regio

Biomes

  1. Biomes are large geographic regions characterized by distinct climate, vegetation, and wildlife.
  2. Each biome represents a specific type of ecosystem with unique biotic and abiotic factors.
  3. The classification of biomes is primarily based on temperature and precipitation patterns.
  4. Biomes can be broadly categorized into terrestrial and aquatic biomes.
  5. Examples of terrestrial biomes include forests, grasslands, deserts, and tundra.
  6. Aq

Ecosystems

  1. Ecosystem refers to a community of living organisms interacting with each other and their physical environment.
  2. Ecosystems consist of biotic components (plants, animals, microorganisms) and abiotic components (soil, water, air, sunlight).
  3. The concept of the ecosystem was first introduced by ecologist Arthur Tansley in 1935.
  4. Ecosystems can be classified into terrestrial ecosystems (forests, deserts, grasslands) and aquatic ecosystems (freshwater and marine).
