resources

General Resource Concepts

Resources: Materials or substances used to produce goods and services.

Renewable Resources: Resources that can be replenished naturally over time, such as solar energy and wind.

Non-Renewable Resources: Resources that cannot be replaced once they are used up, like fossil fuels and minerals.

Sustainable Development: Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Resource Management: Strategic planning and utilization of resources to maximize efficiency and sustainability.

Overexploitation: Excessive use of resources leading to depletion and environmental degradation.

Ecological Footprint: Measure of environmental impact, expressed as the land required to sustain resource consumption.

Social Equity: Fair distribution of resources and opportunities among all members of society.

Local vs Global Resources: Sourced locally for community use versus sourced globally, affecting sustainability.

Resource Conflict: Disputes arising from competition for scarce resources, leading to social and political tensions.

Water Resources and Management

Water Scarcity: Situation where water demand exceeds available supply.

Water Stress: Situation where the amount of water available does not meet the required demand.

Areas of Water Deficit: Locations with insufficient rainfall causing water shortages.

Areas of Water Surplus: Locations with more water than is needed.

Increasing Water Demand: Driven by appliances, warmer climate, population growth, and less fresh water available.

Sustainable Water Usage: Shorter showers, washing full laundry loads, and collecting rainwater.

Kielder Dam Case Study

Location and Overview: Located in Northumberland; largest artificial water reservoir in the UK.

Water Delivery: Delivers water to Newcastle, Sunderland, and London via Newark.

Capacity and Energy: Supplies $1,000\,\text{million}$ litres of water per day and provides $20,000\,\text{MWh}$ of electricity per year via hydropower.

Cost and Scale: Cost $\pounds 167\,\text{million}$, flooded an area of $10\,\text{km}^2$, and displaced $60+$ residents.

Pros: Reliable water supply, renewable energy, flood control, and local job creation.

Water Pollution

Social Effects: Less clean drinking water, health issues, and poisoned water supplies.

Economic Effects: Expensive to clean and treat polluted water.

Environmental Effects: Destroys ecosystems and causes eutrophication.

Eutrophication Process: Fertilizer nutrients leak into water $\rightarrow$ algae grows rapidly $\rightarrow$ blocks sunlight and depletes oxygen $\rightarrow$ kills aquatic plants and animals.

Management Strategies: Legislation, public education, waste water treatment, pollution traps, and green roofs.

Energy Resources and Management

Energy Resources: Sources harnessed to produce power, including fossil fuels, nuclear, and renewables.

Energy Mix: Range of energy sources utilized by a specific region.

Reduced Domestic Energy Consumption: Caused by higher costs, energy-efficient appliances, and increased public awareness.

Fossil Fuels

Definition: Natural fuels formed from the fossilized remains of organisms.

UK Coal Usage: Decreased significantly to reduce $\text{CO}_2$ emissions.

Pros: Requires a small land footprint for a large quantity of energy output.

Cons: Releases high $\text{CO}_2$ emissions, high resource costs, and must be imported to the UK.

Nuclear Energy

Pros: Generates no direct $\text{CO}_2$ emissions; creates jobs in research and development.

Cons: Expensive, produces nuclear waste, and carries risks of frequent accidents.

Wind Turbines

Pros: Infinite renewable source, surrounding land remains usable, long-term cost savings, excess electricity can be sold back to the grid.

Cons: Visual impact, weather dependent, requires significant land space, high initial installation cost.

NIMBY: "Not In My Backyard" local opposition to infrastructure developments.

Fracking

Process:

1. Drilling a deep well into shale gas deposits.

2. Fracking fluid is pumped down the well at extremely high pressure.

3. Fluid fractures surrounding rock to create fissures where shale gas flows out.

Pros: Creates jobs and increases national energy security.

Cons: Causes minor earthquakes, noise pollution, expensive, pollutes and consumes water, uses toxic chemicals.

Food Resources and Agriculture

Food Security: State where all people have access to sufficient, safe, and nutritious food.

Green Bean Farming in Kenya

Employment: Creates $500$ jobs per farm.

Positives: Export earnings from High-Income Countries (HICs) and wage taxes that fund local projects.

Negatives: Reduces available farmland for local food crops (causing shortages), consumes local water supply, and workers face low wages and chemical exposure.

Almeria Greenhouses Case Study (Spain)

Scale and Revenue: Covers $26,000\,\text{hectares}$ and generates $\$1.5\,\text{billion}$ per year.

Climate and Drivers: Receives $3,000$ hours of sunlight per year; built due to cheap immigrant labor, high sunlight, and Spanish government funding.

Advantages: Job creation, advances in hydroponics technology, and supplies fruit and vegetables to Europe year-round.

Disadvantages: Plastic dumped into the sea, workers underpaid, and local temperature drop caused by reflective greenhouse roofs.

Sustainable Farming: Rice-Fish Farming

Mechanism: Small fish are introduced into flooded rice paddy fields to eat pests and fertilize crops naturally.

Environmental Degradation and Sustainability

Waste Management: Collection, transport, processing, recycling, or disposal of waste materials.

Pollution: Introduction of harmful substances into the environment, affecting air, water, and soil quality.

Climate Change: Long-term changes in temperature and weather patterns linked to human resource consumption.
