Welcome to Resource Management!
In this chapter, we are going to explore the "stuff" that makes the world go round: resources. We will look at what they are, why some countries have more than others, and how we can look after them so they don't run out. This is a vital part of your "Human Environment" paper, and it’s really important because it’s about how we survive and thrive on our planet.
Don't worry if some of this seems like a lot to remember—we'll break it down step-by-step with simple examples!
1. What is a Natural Resource?
A natural resource is anything that comes from the environment that humans can use. Think of it as nature’s "gift shop." We can group these resources in two main ways:
Biotic vs. Abiotic
1. Biotic resources: These are living things or things that were once alive (like fish, trees, or fossil fuels which come from ancient plants/animals).
2. Abiotic resources: These are non-living things (like water, air, gold, and rocks).
Renewable vs. Non-renewable
1. Renewable resources: These can be used over and over again because they "recharge" naturally (like sunlight, wind, and water).
2. Non-renewable resources: These are "one-time use" items. Once they are gone, they are gone forever (like coal, oil, and gas).
Memory Aid: The Battery Analogy
Think of Non-renewable resources like a standard AA battery—once it's flat, you throw it away. Renewable resources are like a rechargeable battery or a solar-powered calculator—they keep on going!
How we use (and change) the environment
To get these resources, we have to change the land. This is called exploitation. Here are some examples:
1. Farming: We clear forests to grow food (deforestation).
2. Fishing: We take fish from the sea, which can lead to reduced biodiversity (fewer types of creatures).
3. Mining/Drilling: We dig for coal or drill for oil, which can cause soil erosion and air/water pollution.
Quick Review:
- Biotic = Living / Abiotic = Non-living.
- Renewable = Infinite / Non-renewable = Finite.
- Exploiting resources usually harms the environment (pollution, habitat loss).
Takeaway: Resources are essential for life, but getting them usually has a "cost" to the planet.
2. Who Has the Resources? (Distribution and Consumption)
The world isn't "fair" when it comes to resources. Some places have a lot, and some have very little. This is called uneven distribution.
Global Distribution
1. Food: Places with flat land and good weather (like Europe) produce lots of food. Dry or mountainous places (like parts of Africa or the Himalayas) struggle.
2. Energy: Some countries sit on huge "puddles" of oil (like Saudi Arabia), while others have to buy it from them.
3. Water: Rainy countries (like Brazil or Canada) have a water surplus. Dry countries (like Egypt) have a water deficit.
Consumption (Usage)
Generally, Developed countries (richer countries like the UK or USA) consume way more resources than Developing countries.
Example: A person in a rich country might use as much energy in a day as a person in a poor country uses in a whole month!
Did you know?
As countries like China and India become wealthier (Emerging countries), their demand for resources like meat and electricity is skyrocketing!
Takeaway: Wealthy countries usually have more resources and use them much faster than poorer countries.
Optional Sub-topic 6A: Energy Resource Management
(Check with your teacher if you are studying Energy or Water!)
Renewable vs. Non-Renewable Energy
We use different sources to make electricity:
Non-Renewable: Fossil fuels (Coal, Oil, Gas) and Uranium (Nuclear).
- Pros: Reliable and cheap for now.
- Cons: Releases CO2 (Global Warming) and will run out.
Renewable: Solar, Wind, and Hydro-electric (HEP).
- Pros: Clean and never runs out.
- Cons: Can be expensive to build and depends on the weather (no wind = no power).
The UK's Energy Mix
The energy mix is just a fancy way of saying "the recipe of different energy sources a country uses."
- In the past, the UK relied almost entirely on Coal.
- Today, we use much more Gas and Renewable energy (especially wind power). We are trying to phase out coal completely to help the environment.
Why is demand for energy increasing?
1. Population growth: More people = more lightbulbs and TVs!
2. Wealth: As people get richer, they buy more gadgets and cars.
3. Technology: Think about how many things you charge every day compared to your grandparents at your age!
New Technology: Fracking
Fracking is a way of getting gas out of rocks deep underground by blasting them with high-pressure water. It could help solve energy shortages, but many people worry it causes small earthquakes and pollutes drinking water.
Takeaway: The world is trying to shift from "dirty" fossil fuels to "clean" renewable energy, but it’s a difficult and expensive process.
Optional Sub-topic 6B: Water Resource Management
(Check with your teacher if you are studying Energy or Water!)
Water Surplus and Deficit
- Water Surplus: When a place has more water than it needs (it rains a lot!).
- Water Deficit: When there isn't enough water for everyone (dry climate or too many people).
The UK’s Water Problem
You might think the UK is always rainy, but we have a big problem: Imbalance.
- Most of the rain falls in the North and West (where fewer people live).
- Most of the people live in the South East (where it is much drier).
- We also have ageing infrastructure—old pipes that leak millions of litres of water every day!
How do different countries use water?
1. Developed Countries: Use lots of water for industry and domestic use (showers, dishwashers).
2. Developing Countries: Use the vast majority of their water (up to 90%) for agriculture (farming/irrigation).
Solving Water Shortages: Desalination
Desalination is a technology that takes the salt out of seawater to make it drinkable.
- Pro: It provides water in desert areas near the sea.
- Con: It uses a huge amount of energy and is very expensive.
Common Mistake to Avoid:
Don't confuse water stress with just "having no water." Water stress happens when the demand for water is higher than the amount available during a certain period, or when poor quality limits its use.
Takeaway: Water is unevenly distributed. We need to manage it sustainably by fixing leaks and using new technology like desalination.
Final Summary & Sustainability
To keep the world running, we need Sustainable Management. This means using resources in a way that meets our needs today without ruining things for people in the future.
How can we be sustainable?
- Individuals: Recycling, using less water, and switching off lights.
- Governments: Investing in renewable energy and protecting forests.
- International: Countries working together to reduce carbon footprints.
Encouraging Note: You've reached the end of the Resource Management notes! These topics are all about the choices we make as a society. Keep thinking about how these resources affect your daily life, and you'll find the exam questions much easier to answer!
