Explain the role of climate in the distribution and density of population in India.
Show Hint
Population distribution in India largely follows climatic suitability: the most densely populated areas are those with moderate temperatures, reliable rainfall, and fertile soils, while deserts, mountains, and regions with extreme climates remain sparsely populated.
Climate plays a fundamental role in shaping the distribution and density of population in India. It acts as both a pull factor and a push factor, influencing where people choose to settle and thrive. The following points explain this relationship in detail:
Favorable Climate in Coastal and Riverine Areas: Regions with moderate and pleasant climates, such as coastal areas (e.g., Mumbai, Chennai, Kolkata) and river plains (e.g., the Ganga-Brahmaputra basin), have high population densities. These areas experience less extreme temperatures and receive adequate rainfall, making them suitable for agriculture, trade, and habitation.
Extreme Climates and Low Population Density: Areas with harsh climatic conditions tend to have sparse populations. For example:
Thar Desert (Rajasthan): Extremely hot and arid climate with low rainfall makes agriculture difficult, resulting in low population density.
Himalayan Region: Extremely cold temperatures, rugged terrain, and snow cover for most of the year limit human settlement, leading to very low population density.
Northeastern Hills: Heavy rainfall and dense forests, coupled with rugged topography, restrict large-scale human habitation.
Monsoon Dependency and Agricultural Productivity: The Indian economy, particularly agriculture, is heavily dependent on the monsoon. Areas receiving reliable and adequate rainfall (e.g., the Western Ghats, delta regions) support intensive farming and, consequently, high population densities. In contrast, regions with erratic or low rainfall (e.g., parts of the Deccan Plateau) have lower agricultural productivity and thus lower population densities.
Temperature Extremes and Livability: Regions with extreme temperatures, either too hot (central India) or too cold (Ladakh), discourage dense settlement. Moderate temperatures, found in the northern plains and coastal strips, are more conducive to human health, economic activities, and overall comfort, attracting larger populations.
Climate-Induced Migration: Adverse climatic conditions, such as droughts, floods, or extreme temperatures, often lead to migration. People from climatically unfavorable regions (e.g., drought-prone areas of Maharashtra or Rajasthan) move to cities or agriculturally prosperous regions with better climatic conditions, further concentrating population in favorable areas.
Impact on Economic Activities: Climate directly influences the types of economic activities possible in a region. For instance, the cool climate of hill stations like Darjeeling and Ooty supports tea plantations, attracting a workforce. Similarly, the warm and humid climate of coastal areas supports fishing and trade, leading to clustered settlements.
In summary, climate acts as a primary determinant of population distribution in India. Areas with moderate, resource-rich climates support high population densities, while regions with extreme climates, whether arid or freezing, remain sparsely populated. This climatic influence is further reinforced by the availability of water, agricultural potential, and economic opportunities.
