Important Paper 1 People, Development and Environment Topics for UGC NET
The following are important topics for People, Development and Environment for UGC NET Exam:
1. Development and Environment
Development can be defined as improvements in economic, social, and human situations. But the activities of development have an impact on the environment as well. That is why the development must take into account the environmental protection and future generations’ requirements.
For example, industrialisation and urbanisation can increase:
- Energy consumption
- Resource use
- Waste generation
- Pollution
- Pressure on land and water
2. Sustainable Development
The sustainable development strategy seeks to ensure that current requirements are met without limiting the capacity of future generations to satisfy their needs. The Sustainable Development Goals (SDGs) offer a platform in which social, economic, and environmental issues are addressed.
It focuses on balancing:
- Economic development
- Social well-being
- Environmental protection
Important Principles
- Conservation of natural resources
- Intergenerational equity
- Efficient resource use
- Environmental protection
- Social inclusion
3. Natural Resources
Natural resources are resources obtained from nature and used by humans.
They can broadly be classified into renewable and non-renewable resources.
Renewable Resources
These resources can naturally replenish over time.
Examples:
- Solar energy
- Wind energy
- Water
- Forests
- Biomass
Non-Renewable Resources
These resources are available in limited quantities and take very long periods to form.
Examples:
- Coal
- Petroleum
- Natural gas
- Minerals
Renewable vs Non-Renewable Resources
| Renewable Resources | Non-Renewable Resources |
| Can replenish naturally | Limited in quantity |
| Generally available continuously when managed properly | Take very long to form |
| Solar and wind energy | Coal and petroleum |
| Can support long-term resource use | Excessive use can lead to depletion |
4. Water Resources
Water is essential for human life, agriculture, industry and ecosystems. Water conservation and efficient water management are important for sustainable development.
Major sources include:
- Rivers
- Lakes
- Groundwater
- Rainfall
- Reservoirs
Major water-related issues include:
- Water scarcity
- Groundwater depletion
- Water pollution
- Unequal distribution
- Floods and droughts
5. Energy Resources
Energy resources can also be classified as renewable and non-renewable.
Renewable Energy
Examples:
- Solar energy
- Wind energy
- Hydropower
- Geothermal energy
- Biomass energy
Non-Renewable Energy
Examples:
- Coal
- Petroleum
- Natural gas
Greater use of renewable energy can help reduce dependence on fossil fuels and lower environmental impacts.
6. Environmental Pollution
Pollution refers to the introduction of harmful substances or forms of energy into the environment.
Major types include:
- Air pollution
- Water pollution
- Soil pollution
- Noise pollution
- Radioactive pollution
Air Pollution
Air pollution occurs when harmful gases, particles or other pollutants enter the atmosphere.
Major sources include:
- Vehicles
- Industries
- Burning of fossil fuels
- Construction activities
- Open burning
Common air pollutants include particulate matter, carbon monoxide, sulphur dioxide and nitrogen oxides.
Water Pollution
Water pollution occurs when harmful substances contaminate water bodies.
Sources include:
- Industrial waste
- Domestic sewage
- Agricultural runoff
- Chemicals
- Plastics
Soil Pollution
Soil pollution can result from:
- Excessive use of chemicals
- Industrial waste
- Pesticides
- Improper disposal of solid waste
Noise Pollution
Noise pollution is excessive or unwanted sound that can affect human health and the environment.
Major sources include:
- Traffic
- Industries
- Construction
- Loudspeakers
7. Waste Management
Waste management involves the collection, treatment, processing, recycling and safe disposal of waste.
Important types include:
- Solid waste
- Plastic waste
- Biomedical waste
- E-waste
- Hazardous waste
Waste Management Hierarchy
A commonly used approach gives priority to:
Reduce → Reuse → Recycle → Recovery → Disposal
Reducing waste generation is generally preferred over disposal.
8. Climate Change
Climate change can be defined as any change in temperatures and weather patterns. The contribution of man’s activities towards climate change cannot be undermined as he is largely responsible for climate change at present.
Major concerns include:
- Rising temperatures
- Changes in rainfall patterns
- Melting of glaciers and ice sheets
- Sea-level rise
- Extreme weather events
- Impacts on agriculture and ecosystems
9. Global Warming
Global warming is defined as the sustained rise in the temperature of the earth’s surface. Global warming is related to the rise in greenhouse gases in the atmosphere.
Important greenhouse gases include:
- Carbon dioxide
- Methane
- Nitrous oxide
- Water vapour
Global Warming vs Climate Change
| Global Warming | Climate Change |
| Long-term rise in average temperature | Broader long-term changes in climate |
| One major component of climate change | Includes temperature, rainfall and other changes |
| Strongly linked to greenhouse gas increase | Has wider environmental and climatic effects |
10. Greenhouse Effect
Greenhouse effect is a natural process where certain gases present in the atmosphere hold some of the energy radiating from the earth’s surface. Greenhouse effect in its natural form makes the earth habitable. But higher levels of greenhouse gases may enhance the effect.
Greenhouse gases include:
- Carbon dioxide
- Methane
- Nitrous oxide
- Water vapour
11. Biodiversity
Biodiversity refers to the variety of living organisms and ecosystems.
It can be understood at three major levels:
- Genetic diversity
- Species diversity

- Supports food systems
- Provides natural resources
- Supports livelihoods
- Provides ecosystem services
- Has scientific and cultural value
Major threats include:
- Habitat loss
- Pollution
- Climate change
- Overexploitation
- Invasive species
12. Ecosystem
An ecosystem consists of living organisms and their physical environment interacting with each other.
Components
- Biotic components: Living organisms such as plants, animals and microorganisms.
- Abiotic components: Non-living factors such as air, water, soil, temperature and sunlight.
Food Chain
A food chain shows the transfer of energy from one organism to another.
A simple example is:
Plants → Herbivores → Carnivores
Important ecological concepts include:
- Producers
- Consumers
- Decomposers
- Food chain
- Food web
- Ecological pyramid
13. Deforestation
Deforestation refers to the removal or clearing of forests.
Major causes include:
