Posted on Sep 27, 2025 in Geography

Understanding the Environment

Environment refers to the conditions that influence human life.
It includes living (biotic) and non-living (abiotic) elements, such as birds, animals, forests, air, water, and land.
It encompasses all biotic and abiotic factors that influence each other.
Environment includes water, air, and land, and the interrelationships among water, air, land, human beings, other creatures, plants, microorganisms, and property.

Significance of Our Environment

Environment Offers Production Resources

The environment supplies vital resources important for production.
Resources include renewable and non-renewable resources like trees, plants, and fossil fuels.
These natural resources are used as inputs for producing goods and services.

Environment Sustains Life

It includes the basic elements required for survival, such as air, water, soil, and sunlight.
The environment possesses the capacity to support life.
The absence of essential elements like air and water implies the end of life.

Environment Assimilates Waste

During the production process, significant waste is generated.
Waste generation occurs as garbage. The environment absorbs waste created by production and consumption activities.

The Current Environmental Crisis

The opportunity cost of negative environmental impacts is substantial.
Many resources have become extinct, and waste generation now exceeds the environment’s absorptive capacity.
Industrial development has polluted and depleted rivers and aquifers, making water an economic good.
Intensive extraction of both renewable and non-renewable resources has depleted vital reserves, compelling us to invest heavily in technology and research for new resources.
Compounding these issues are the health costs of degraded environmental quality; declining air and water quality has led to increased incidence of respiratory and water-borne diseases, consequently raising healthcare expenditures.
Global environmental issues like global warming and ozone depletion also contribute to increased financial commitments for governments.

Resource Supply-Demand Reversal

In early civilizations, before the phenomenal increase in population and industrialization, the demand for environmental resources and services was significantly less than their supply.
This meant pollution remained within the environment’s absorptive capacity, and resource extraction rates were below regeneration rates.
Consequently, environmental problems did not arise.
However, with population explosion and the Industrial Revolution, to meet the growing needs of an expanding population, circumstances changed. The demand for resources for both production and consumption surpassed their regeneration rates.

India’s Environmental Challenges

The threat to India’s environment poses a dichotomy:
- Threat of poverty-induced environmental degradation.
- Threat of pollution from affluence and a rapidly growing industrial sector.
The priority issues identified are:

Land Degradation

It refers to a decline in land fertility and soil quality.
It occurs due to soil erosion, unsustainable use, and inappropriate management practices.

Factors Contributing to Land Degradation

Shifting cultivation.
Forest fires and overgrazing.
Improper crop rotation.
Unsustainable fuelwood and fodder extraction.

Soil Erosion

It means the loss of the topsoil layer, which contains major nutrients for plant growth.

Excessive waterlogging on the soil surface reduces its fertility.
Estimates indicate that soil is eroding at a rate of 5.3 billion tonnes per year across the country.

Deforestation

It is a continuous decrease in forest area. Forest cover is an indicator of land quality.
It is due to tree cutting to meet raw material demands for growing industrialization.
Deforestation arises from urbanization, as more forests are cleared for town development.
Multi-purpose river projects, such as the Bhakra Dam, are another contributing factor to deforestation.

Consequences of Deforestation

Negative effects on wildlife and plant life.
Deterioration in land resource quality.

Pollution

It refers to chemical substances that contaminate the environment.

The Central Pollution Control Board (CPCB) has identified seventeen categories of industries as significantly polluting.

Air Pollution

Air pollution means the presence of air pollutants harmful to human beings, animals, and vegetation.
The causes include rapid industrialization, urbanization, and thermal power plants.

Factors Contributing to Air Pollution

Smoke emitted by industries due to fossil fuel use.

Water Pollution

Water pollution means the presence of water pollutants that contaminate or degrade water quality.
The causes include rapid industrialization, refineries, and more.
A major concern is the rapid growth of industries like textiles, chemicals, and refineries.
Soil erosion and the decay of organic matter mixed with pesticides and insecticides run into streams and rivers, contaminating water.

Noise Pollution

Noise pollution means discomfort and irritation caused by loud sounds.
Noise from loudspeakers, vehicles, animals, and machines causes noise pollution.

Major Sources of Noise Pollution

Sound from heavy machinery.
Sound from automobiles.

Sustainable Development Principles

It refers to a development strategy that meets the needs of the present generation without compromising the ability of future generations to meet their own needs.
It enables all generations to make optimal use of resources.
Development that ensures all future generations can enjoy a potential average quality of life at least as high as the current generation.
The Brundtland Commission emphasizes protecting future generations.

Steps to Achieve Sustainable Development

Limiting human population to a level within the environment’s carrying capacity.
The environment’s carrying capacity is akin to a ship’s ‘plimsoll line,’ its load limit mark.
Without a ‘plimsoll line’ for the economy, human activities can exceed Earth’s carrying capacity, hindering sustainable development.
Technological progress should be input-efficient, not input-consuming.
Renewable resources should be extracted sustainably; the rate of extraction should not exceed the rate of regeneration.
For non-renewable resources, the depletion rate should not exceed the rate of creation of renewable substitutes.
Inefficiencies arising from pollution must be corrected.

Strategies for Sustainable Development

Solar Energy Utilization

India is naturally endowed with abundant solar energy in the form of sunlight.
Photovoltaic cells can convert solar energy into electricity.
These cells use special materials to capture and convert solar energy into electricity.

Harnessing Wind Power

In areas with consistently high wind speeds, windmills can provide electricity without adverse environmental effects.
Wind turbines move with the wind, generating electricity.
Undoubtedly, the initial cost is high.

Mini-Hydel Plants

In mountainous regions, streams are ubiquitous, with a large percentage being perennial.
Mini-hydel plants harness the energy of these streams to move small turbines.
The turbines generate electricity for local use.

Promoting Organic Farming

Organic farming can substitute chemical fertilizers, which reduce soil fertility and future production capacity.
Organic farming focuses on soil health and prevents water pollution.
In certain parts of the country, cattle are maintained primarily for their dung, an important fertilizer.
Biopest control involves using natural substances; for example, several pest-controlling chemicals isolated from neem are now in use.

LPG and Gobar Gas in Rural Areas

Rural households typically use wood, dung cakes, or other biomass as fuel.
LPG is a clean fuel that significantly reduces household pollution and minimizes energy waste.
Additionally, gobar gas plants are being provided through easy loans and subsidies.
For gobar gas plants to function, cattle dung is fed into the plant, producing gas for fuel. The leftover slurry is an excellent organic fertilizer and soil conditioner.

Comparative Growth Strategies: India, Pakistan, China

India, Pakistan, and China share similarities in their development strategies.
All three nations embarked on their developmental paths concurrently.
While India and Pakistan gained independence in 1947, the People’s Republic of China was established in 1949.
All three countries began planning their development strategies similarly: India announced its first five-year plan in 1951, Pakistan its first (now called medium-term developmental plan) in 1956, and China its first in 1953.
India and Pakistan adopted similar strategies, such as creating large public sectors and increasing expenditure on social development.
Until the 1980s, all three countries exhibited similar growth rates and per capita incomes.

China’s Economic Growth Journey

The People’s Republic of China was established, and the government regulated the country. All individual-owned enterprises and land were brought under government control.
The economy was agrarian, but the Great Leap Forward campaign was initiated in 1958 to foster industrialization.
It encouraged people to establish industries in their backyards.
In rural areas, communes were established. Under the commune system, people collectively cultivated land.

Challenges of the Great Leap Forward

A severe drought caused havoc in China, killing approximately 30 million people.
When Russia had conflicts with China, it withdrew its professionals who had previously been sent to China to assist in the industrialization process.

Reasons for China’s Slowed GDP Growth

Demand for Chinese products has reduced in global economies.
The Chinese economy slowed due to reduced domestic investment.
Chinese people were migrating to other countries in search of skilled job opportunities.
Environmental degradation became a concern in China as more industries were established, posing a serious challenge to sustainable development.

Pakistan’s Economic Development Path

Pakistan adopted various economic policies similar to India’s.
Pakistan also followed a mixed economy model with the co-existence of public and private sectors.
In the late 1950s and 1960s, Pakistan introduced various policies, such as tariff protection for consumer goods manufacturing alongside direct import controls on competing imports.
The introduction of the Green Revolution transformed the agrarian sector, leading to increased public investments in infrastructure, which ultimately boosted food grain production.
In the 1970s, nationalization of capital goods industries occurred. Pakistan then shifted its policy, introducing denationalization to encourage the private sector.
They received financial support from Western countries and also government financial support for the private sector.
In 1988, Pakistan introduced economic reforms.

Reasons for Pakistan’s Slowdown and Poverty

Agricultural growth and food supply were based not on an institutionalized process of technical change but on good harvests. When harvests were good, the economy thrived; otherwise, economic indicators showed stagnation or negative trends.
A country that builds foreign exchange earnings through sustainable export of manufactured goods has less to worry about. In Pakistan, most foreign exchange earnings came from remittances from Pakistani workers in the Middle East and the export of highly volatile agricultural products.
There was also growing dependence on foreign loans, coupled with increasing difficulty in repayment.
