Bushfires and Floods in Australia

Bushfires

• Causes: Natural occurrences (lightning) or human-caused (accidental or deliberate) **
• Impacts: Loss of life, property damage, environmental degradation, and impact on the economy
• Factors influencing bushfires: Climate (hot, dry, windy conditions), vegetation (fuel), and topography (slope and aspect).
• Bushfire spread: Driven by wind, topography, fuel availability, and temperature.
• Types of bushfires: Ground fire, surface fire, crown fire, and ember attack
• Staying safe: Follow official advice, prepare an evacuation plan, and create a bushfire plan.

### Floods

• Causes: Heavy rainfall, overflowing rivers, and storm surges.
• Impacts: Loss of life, property damage, displacement of people, and damage to infrastructure.

Indigenous Changes to the Environment

• Impacts: Indigenous Australians have shaped the Australian environment for thousands of years through practices like fire management and land clearing.

Geographic Characteristics

• Physical characteristics: Climate, landforms, soils, and vegetation.
• Human characteristics: Population, infrastructure, culture, and economy.

Zoning

• Purpose: To regulate land use and development to achieve sustainable growth and protect the environment.
• Characteristics: Residential, commercial, industrial, and recreational zones.

Sustainability

• Definition: Meeting the needs of the present without compromising the ability of future generations to meet their own needs.
• Factors affecting the environment: Population growth, resource consumption, pollution, and climate change.

Climate Change

• Definition: A long-term change in the Earth's climate system, primarily caused by human activities.
• Impact on communities: More extreme weather events, rising sea levels, and changes in agricultural productivity.
• Developed communities: Often have more resources to adapt to climate change, but may face challenges in managing infrastructure.
• Less developed communities: May be more vulnerable to the impacts of climate change due to limited resources and infrastructure.

Greenhouse gases

• Production: Caused by burning fossil fuels, deforestation, and industrial processes.
• Strategies for reduction: Renewable energy sources, energy efficiency, and carbon capture and storage.

Carbon Footprint

• Impact: Greenhouse gas emissions linked to a person's or organization's activities.
• Strategies for reduction: Reduce energy consumption, choose sustainable products, and support policies that promote climate action.

Plastic Waste

• Impact: Environmental pollution, wildlife harm, and ocean acidification.
• Strategies for reduction: Reduce single-use plastics, recycle and reuse plastics, and support policies that promote plastic waste reduction.
