    Determinants of Fertility

    Fertility lies at the heart of population studies. It is the biological capacity of a woman to give birth, but when we talk about fertility in population geography, we are not just referring to biology—we are talking about a complex interplay of biological, demographic, social, and economic factors that influence the actual number of children…

    Factors of Population Distribution

    Population distribution and density are shaped by a complex interplay of physical, socio-cultural, and demographic factors. The way people settle in various regions depends on a combination of environmental conditions, historical influences, economic opportunities, and social dynamics. While some areas naturally attract larger populations due to favorable conditions, others remain sparsely populated due to challenging…

  • Land Degradation and Conservation

    Introduction We have already studied about land degradation and conservation in Biogeography. Here we will mostly focus on land degradation and conservation from environment point of view. However, before starting let’s revise a bit what we had studied: Soil Degradation Causes of Soil Degradation Soil Erosion Soil Conservation Increasing Degraded Land in India Land is…

  • Pollution from Industries

    When we study environmental regulation in India, a major focus is on industries that have a disproportionately large impact on air and water quality. The government identifies these industries, categorises them, and then monitors them through specialised systems. Let’s understand this: Highly Polluting Industries (HPIs) The Ministry of Environment, Forest and Climate Change (MoEFCC) has…

  • Electronic Waste (E-Waste)

    Electronic waste (e-waste) is one of the fastest-growing waste streams in the world, and also one of the most dangerous, because it mixes:→ hazardous substances→ heavy metals→ toxic chemicals→ plastics & flame retardants……with valuable metals such as gold, silver, copper, platinum. What is E-Waste? E-waste includes discarded or end-of-life:→ electronics→ electrical equipment (EEE)→ appliances (TVs,…

  • Heavy Metals

    Introduction Heavy metals are among the most dangerous environmental pollutants because they:➡️Persist in the environment➡️Do not biologically degrade➡️Accumulate in living organisms➡️Move up the food chain (biomagnification) Even at very low concentrations, they can cause severe and irreversible health effects. What Are Heavy Metals? Heavy metals are metallic elements with densities higher than water and with…
