Explain any three human activities responsible for land degradation in India

Question

Answer

(a) Mining : Mining sites are abandoned after excavation work is complete leaving deep scars in states such as Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha. Deforestation due to mining has caused severe land degradation.

(b) Over irrigation : Over irrigation in the states of Punjab, Haryana, Western Uttar Pradesh, has caused water logging and increase in salinity of soil.

(c) Overgrazing : Overgrazing in states such as Gujarat, Rajasthan, Madhya Pradesh and Maharashtra is a huge cause due to cattle population.

(d) Industries : Mineral processing industry like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust, this retards the process of infiltration of water into the soil.

(e) Industrial Waste : Industrial effluents also have become a major source of land degradation.

Answer

Cutting of trees in large area, making big dams, mines and other big infrastructures can affect in land degradation.

Answer

Human activities play a significant role in land degradation in India. Here are three major activities responsible for land degradation in the country:

1. Deforestation:
Deforestation is a major contributor to land degradation in India. It involves the clearing of forested areas for various purposes, such as agriculture, logging, urbanization, and infrastructure development. The removal of trees leads to soil erosion, loss of biodiversity, and disruption of ecosystems. Deforestation also reduces the capacity of forests to absorb carbon dioxide, contributing to climate change.

- Soil Erosion: The removal of trees exposes the soil to wind and water erosion, leading to the loss of topsoil, which is rich in nutrients essential for plant growth. As a result, the fertility of the soil decreases, affecting agricultural productivity.

- Loss of Biodiversity: Deforestation destroys habitats and disrupts ecosystems, leading to the loss of plant and animal species. This loss of biodiversity affects the overall balance and resilience of ecosystems, reducing their ability to provide essential ecosystem services.

- Climate Change: Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere. Deforestation reduces the capacity of forests to sequester carbon, contributing to increased greenhouse gas emissions and climate change.

2. Agricultural Practices:
Unsustainable agricultural practices are another major cause of land degradation in India. Intensive farming techniques, excessive use of chemical fertilizers and pesticides, and improper irrigation methods have detrimental effects on the land.

- Soil Degradation: Overuse of chemical fertilizers and pesticides can lead to soil degradation, as they can alter the soil composition and reduce its fertility. Improper irrigation practices, such as excessive use of water or inefficient irrigation systems, can result in waterlogging and salinization of the soil, rendering it unsuitable for cultivation.

- Land Fragmentation: Rapid urbanization and population growth have led to the fragmentation of agricultural land into smaller plots. Fragmentation reduces the efficiency of farming operations and decreases the agricultural productivity of the land.

3. Mining and Industrial Activities:
Mining and industrial activities have a significant impact on land degradation in India. The extraction of minerals and the establishment of industries can result in the destruction of natural habitats, pollution of air and water, and disruption of ecosystems.

- Land Disturbance: Mining activities involve the removal of vegetation and topsoil, leading to land degradation. Excavations and waste dumps can alter the landscape, affecting the natural drainage patterns and causing soil erosion.

- Pollution: Industrial activities release pollutants such as heavy metals, chemicals, and effluents into the environment. These pollutants can contaminate the soil, water bodies, and the air, adversely impacting the quality of land and reducing its productivity.

- Habitat Destruction: Mining and industrial activities often result in the destruction of natural habitats, displacing wildlife and threatening biodiversity. The loss of habitats can disrupt ecological processes and result in the decline of many species.

In conclusion, deforestation, unsustainable agricultural practices, and mining/industrial activities are three major human activities responsible for land degradation in India. These activities have severe consequences such as soil erosion, loss of biodiversity, decreased agricultural productivity, and pollution. It is crucial to promote sustainable land management practices, afforestation, and the adoption of environmentally friendly techniques to mitigate land degradation and protect the land for future generations.
