Future Resource Scenarios 🌍

Introduction: Why should students care about the future of resources?

Every day, people use water, food, energy, metals, forests, and land without always thinking about where these resources come from or how long they will last. But by 2050, the world’s population may be close to $9.7$ billion, which means even more demand for essentials like electricity, clean water, and food. That makes future resource planning one of the most important geography topics in the modern world 🌱

In this lesson, students will learn how geographers think about the future of resource use, shortage, and security. You will explore how different choices by governments, businesses, and consumers can lead to different outcomes. This is called future resource scenarios. A scenario is not a prediction; it is a possible future based on current trends, decisions, and assumptions.

Learning objectives

By the end of this lesson, students should be able to:

explain key terms linked to future resource scenarios;
apply geography reasoning to compare different possible futures;
connect future resource scenarios to resource consumption and security;
use evidence and real-world examples to support ideas.

What are future resource scenarios?

A future scenario is a carefully thought-out story about what the future could look like. In geography, scenarios help us explore questions like: What if global energy demand keeps rising? What if droughts become more frequent? What if countries invest heavily in renewable energy? These questions matter because resources are unevenly distributed across the planet, while demand is growing in many places.

Future resource scenarios often include three broad possibilities:

Business-as-usual: current patterns continue with limited change.
Sustainable transition: countries reduce waste, improve efficiency, and shift to renewable or low-impact resources.
Resource crisis or scarcity pathway: demand rises faster than supply, causing conflict, price spikes, and inequality.

These categories are simplifications, but they help geographers compare outcomes. The key idea is that the future is shaped by choices as well as by physical limits. For example, a country with limited freshwater may still improve security through desalination, recycling, and water-saving farming technologies 💧

A useful term is resource security, which means having reliable access to enough resources at affordable prices and with low environmental risk. When resource security is weak, people may face shortages, rising costs, or unstable supply chains.

Thinking like a geographer: drivers of future change

Geographers ask why resource demand changes and what forces affect supply. Several major drivers influence future resource scenarios.

1. Population growth and urbanisation

As population grows, more people need food, housing, transport, and electricity. Urban areas often use large amounts of energy and water. A fast-growing city may need new reservoirs, power plants, roads, and waste systems. If planning is weak, shortages can happen quickly.

For example, rapidly expanding cities in parts of sub-Saharan Africa and South Asia may experience pressure on water and sanitation services. If infrastructure cannot keep up, resource insecurity grows.

2. Rising incomes and changing lifestyles

When people become wealthier, they often consume more resources. Diets may shift toward meat and dairy, which require more land, water, and feed than grain-based diets. Car ownership, air conditioning, and electricity use may also rise. This can increase pressure on global supplies.

3. Climate change

Climate change affects future resource scenarios because it changes rainfall patterns, drought frequency, storm intensity, and crop yields. Water security is especially vulnerable. Some regions may face less reliable river flow, while others may experience stronger floods that damage infrastructure.

4. Technology and innovation

Technology can reduce pressure on resources or make new sources available. Examples include solar power, wind power, drip irrigation, precision farming, recycling systems, and smart grids. New technology does not solve every problem, but it can improve efficiency and lower waste.

5. Government policy and international cooperation

Laws, taxes, subsidies, and treaties influence how resources are used. A government can encourage renewable energy, protect forests, or regulate water use. Countries can also work together on shared rivers, oil trade, or climate agreements. Strong governance often improves long-term security.

Three future resource scenarios in detail

Scenario 1: Business-as-usual 📈

In a business-as-usual scenario, current patterns continue. Fossil fuel use remains high, consumption increases, and waste is not reduced enough. This may happen if short-term economic growth is prioritised over long-term sustainability.

In this future, energy demand could keep rising faster than renewable supply. Water stress may increase in dry regions. Food systems may become more vulnerable to climate shocks. Resource security may remain strong in wealthy countries but weaker in poorer countries, widening inequality.

A real-world example is heavy dependence on imported energy. If global oil prices rise suddenly, countries that rely on imports may face inflation and supply insecurity. This shows that resource security depends not only on physical availability but also on access and affordability.

Scenario 2: Sustainable transition 🌿

In a sustainable transition, governments and societies make big changes to reduce environmental impact. Energy systems move toward solar, wind, hydro, geothermal, and other low-carbon sources. Buildings become more efficient. Public transport expands. Food waste falls. Water is recycled and reused.

This scenario improves security because it reduces dependence on limited or politically unstable supplies. For example, if a country invests in rooftop solar, it may reduce reliance on imported fossil fuels. If farmers use drip irrigation, they can grow food with less water.

However, sustainable transition also has challenges. Renewable energy systems need metals such as lithium, copper, and cobalt for batteries, cables, and electronics. If demand for these minerals grows very quickly, mining impacts and supply bottlenecks can appear. So even green transitions require careful planning.

Scenario 3: Resource crisis or scarcity pathway ⚠️

In this scenario, demand rises while supply becomes harder to maintain. Climate change, political conflict, pollution, and poor management all make the situation worse. Water shortages, food insecurity, and energy instability become more common.

For example, prolonged drought can reduce river flow and crop yields at the same time. This may increase food prices and force governments to import more grain. If many countries are affected at once, global markets can become unstable.

Resource crises can also lead to conflict. Shared rivers, transboundary aquifers, and energy routes may become politically sensitive. However, geography shows that conflict is not inevitable. Cooperation and fair management can reduce tension.

Applying IB Geography reasoning to scenarios

IB Geography asks students to do more than memorize facts. students should be able to reason through cause, effect, and comparison.

A strong answer about future resource scenarios should include:

a clear statement of the scenario;
a link between a driver and its effect;
at least one example;
an explanation of why the outcome matters for security.

For instance, if asked how climate change might affect future water security, you could explain that higher temperatures increase evaporation, while unpredictable rainfall makes supply less reliable. This can reduce water available for farming, industry, and households. In dry regions, governments may need to build desalination plants, improve storage, or negotiate water-sharing agreements.

Another useful IB skill is comparison. students may compare two countries or two scenarios. For example, a wealthy country may use technology to reduce water waste, while a lower-income country may struggle because it lacks infrastructure investment. Both face climate stress, but their responses differ because of money, governance, and access to technology.

Linking future scenarios to global resource consumption and security

Future resource scenarios are part of the wider core theme because they show how the world’s patterns of consumption create pressure on supply. Consumption is not equal everywhere. High-income countries often use much more energy and materials per person than low-income countries. Yet low-income countries may face the greatest risk from shortages because they have less money to adapt.

This creates an important geography idea: resource use is global, but impacts are local. For example, demand for rare earth metals in consumer electronics may increase mining in one region, pollution in another, and profits in a third. The environmental and social costs are not spread equally.

Security also has more than one dimension:

physical security: enough resource supply exists;
economic security: resources remain affordable;
environmental security: extraction and use do not cause severe damage;
political security: supply is not disrupted by conflict or instability.

A future scenario can improve one type of security while harming another. For example, expanding biofuels may reduce oil dependence but increase pressure on food crops and land. This is why geographers think in systems, not in simple one-step answers.

Conclusion

Future resource scenarios help students understand that the future is not fixed. Different decisions about energy, food, water, and materials can create very different outcomes. A business-as-usual pathway may deepen shortages and inequality. A sustainable transition can improve long-term security, but it still needs minerals, investment, and good governance. A scarcity pathway shows the risks of inaction and poor planning.

For IB Geography SL, the key skill is to explain how drivers such as population growth, climate change, technology, and policy shape future resource security. students should always connect examples to wider ideas like sustainability, inequality, and global interdependence 🌏
