What is it?

Intergenerational equity means fairness between different generations. It's about making sure that the choices we make today don't harm the ability of future generations to meet their own needs and enjoy a good quality of life.

Simple Example

Quick Example

Imagine your family has a favourite mango tree. If your generation eats all the mangoes and doesn't plant new trees or care for the old one, future generations in your family won't have any mangoes to enjoy. Intergenerational equity means leaving enough for everyone, including those who come after us.

Worked Example

Step-by-Step

Let's say a city has a limited supply of clean groundwater. Current generation uses 1000 litres per day.
--- The total sustainable groundwater available is 500,000 litres, which can naturally replenish over 50 years.
--- If the current generation continues to use 1000 litres/day, they will use 1000 litres/day * 50 years = 18,250,000 litres (approx) over 50 years, which is much more than the sustainable amount.
--- To ensure intergenerational equity, the city must reduce its daily usage to a level that allows the water to replenish, perhaps 500,000 litres / (50 years * 365 days/year) = 27.4 litres per day.
--- This means the current generation needs to drastically cut down on water usage, or find alternative sources, so future generations also have clean water.
--- The goal is to ensure the resource lasts indefinitely for all generations. Answer: Sustainable usage must be much lower, around 27.4 litres per day, to ensure future generations also have access to water.

Why It Matters

Understanding intergenerational equity is crucial for scientists and engineers working on Space Technology, EVs, and Climate Change. It helps them design sustainable solutions, like efficient batteries for EVs that don't deplete rare earth minerals, or space missions that don't create too much orbital debris. Careers in environmental policy, sustainable engineering, and urban planning rely heavily on this concept.

Common Mistakes

MISTAKE: Thinking intergenerational equity only applies to money or wealth. | CORRECTION: It applies to all kinds of resources – natural resources like clean air and water, social resources like education and healthcare, and even cultural heritage.

MISTAKE: Believing it means we can't use any resources today. | CORRECTION: It means using resources wisely and sustainably, ensuring we leave enough for future generations, not that we stop using them entirely.

MISTAKE: Confusing it with charity or simply being 'nice' to future people. | CORRECTION: It's a principle of justice and fairness, implying a responsibility and an ethical obligation, not just a kind gesture.

Practice Questions

Try It Yourself

QUESTION: A village relies on a forest for firewood. If the current generation cuts down trees faster than new ones can grow, is this intergenerational equity? | ANSWER: No, this is not intergenerational equity because future generations will not have access to firewood.

QUESTION: Your school decides to install solar panels to generate electricity. How does this decision relate to intergenerational equity? | ANSWER: Installing solar panels promotes intergenerational equity because it reduces reliance on fossil fuels, which are limited and contribute to climate change, thus preserving resources and a healthy environment for future generations.

QUESTION: A country discovers a large oil reserve. If they extract and sell all the oil within 20 years to boost their economy, what are the potential long-term consequences for future generations in terms of intergenerational equity? List two consequences. | ANSWER: Two potential consequences are: 1. Future generations will not have access to this oil resource for their energy needs or economic benefit. 2. The rapid burning of this oil could contribute significantly to climate change, leaving future generations with a more polluted environment and extreme weather.

MCQ

Quick Quiz

Which of the following best describes intergenerational equity?

Sharing resources equally among people living today.

Ensuring future generations have the same opportunities and resources as the current generation.

Prioritizing the needs of the current generation over future generations.

Donating money to charities for children.

The Correct Answer Is:

Intergenerational equity is about fairness between generations, meaning the choices we make today should not negatively impact the ability of future generations to meet their own needs. Option B correctly captures this idea of ensuring similar opportunities and resources.

Real World Connection

In the Real World

In India, the push for electric vehicles (EVs) by companies like Tata Motors and Ola Electric is a real-world example of intergenerational equity. By reducing reliance on petrol/diesel cars, we're cutting down air pollution and conserving fossil fuels, ensuring cleaner air and more resources for our children and grandchildren.
