define integrated farming
an approach to farming combining traditional methods with modern technology to achieve higher levels of productivity without increasing the environmental impact.
define ecological footprint
a measure of how much productive land(global hectares) is required to produce the grids and services and dispose of the waste necessary to support particular lifestyle.
impact of conservation
- the preservation or restoration of natural environment, natural ecosystem, vegetation and wildlife.
- boardwalks at lily pilly gully(Wilsons prom) – positive impacts:help reduce our impact on the environment because it preserves the vegetation underneath it.
- negative impacts: it disrupts the habitat and some of the vegetation would have been destroyed to make somewhere to build the board walk.
Impacts of recreational activities
- fills human desire and needs
- sea kayaking at tidal river Wilsons prom.
- positives: education, fun, enjoyment, physical exercise and skill development
- negatives: damage to sand dunes or environment- hooded plover and flora species damage.
community based action- are a reminder for us to live in a more sustainable way and provide awareness of having positive impacts on our environment
trust for nature- is a non profit organisation that has the objective of reducing environmental impact through adopting policies, setting targets and developing environmental management strategies to achieve specific goals.
- they work in co operation with private land owners
- 2/3rds of Victoria is privately owned.
- TFN conservation programs- conservation covenants, stewardship programs, trust for nature properties and revolving funds
trust for nature- conservation covenants
- provide permanent protection of native plants and wildlife.
- most effective ways to protect land and it remains attached even if the property is sold
- the agreement is voluntary and is negotiated between trust for nature and the land holder
- backed by state legislation through victorian conservation trust act 1972.
codes of conduct- general info
- ways we can reduce our impact on the environment
- promotes safe and enjoyable participation for people engaging in various outdoor pursuits
- simply a set of rules in the ways we must act when in the outdoors
codes of conduct- bushwalking
- stay on tracks provided
- follow appropriate toiling practices
- minimal impact strategies to leave no trace
- be aware of sensitive areas
impacts of technology- direct and indirect
- technology is how people modify the natural world to suit their own purposes
- it is the application of scientific knowledge utilised to extend human abilities to satisfy our needs.
direct impacts: are those caused by the action and occur at the same time and place, usually observable. EG. snowmaking machinery, land clearing, depletion of water sources.
indirect impacts: are those that are caused by the action but not immediately. they happen before or after the event or later in time but are still reasonably foreseeable. EG. equipment manufacture and transport.
Impacts of urbanisation
urbanisation- development and physical growth of cities and towns.
- the process of urbanisation means that natural environments are impacted due to the need for extra land for the construction of houses and industries.
positives of urbanisation
conservation buildings such as edithvale wetlands education centre
- educates people about surroundings
- Internationally recognised rams site
- protection of native species
negatives of urbanisation- waterways and land
waterways- increased turbidity, rising sea levels, erosion of creeks and water sources and water pollution from litter, garden refuse, soap, petrol,oil,cigarette butts and animal faeces.
land- decrease in biodiversity levels,introcution of weeds , habitat loss through timber harvesting, mining excavation and clearing of vegetation
