Potential Solutions from Current Research
Sustainability = reduce these greenhouse gas emissions at the source
Small impact solutions Eat less milk/meat in the developed world
Large impact solutions Reduce enteric (intestine) fermentation Reduce resource inputs (feed quantity) and frequency of
feeding (how often) Intensify production – more milk/meat per unit of
greenhouse gas emitted, for example, by modifying the feed

Olds Biofuel Technology Centre Biodiesel is a renewable fuel that can be produced from plant oils and/or animal fats.
![Page 21: Lowering the Carbon Footprint: Making More Sustainable in ... › wp-content › pdf › sites › 2 › ... · Presentation Outline Carbon footprint: the total amount of greenhouse](https://reader033.vdocuments.us/reader033/viewer/2022042400/5f0f463c7e708231d443590c/html5/thumbnails/21.jpg)
How Biodiesel is Produced Canola seeds heated and crushed in a screw press to extract the oils
Use lower quality seeds
Oil is filtered and mixed with KOH and a CH4 to convert the oil (triglycerides) into biodiesel and glycerine (comes from the triglycerides).

How Biodiesel is ProducedMethane flashed off in pressure vessel
Centrifuge separates glycerine and biodiesel
Biodiesel resin filters
Subsample campus lab for grading and inspection

How Biodiesel is Produced By‐products Solids pressed cape used for fertilizer, feed, biogas production, burned as fuel, etc.
Methane – collected and reused after flashed off in pressure vessel.
Glycerin – is quite “dirty” but can be used for feed, compost, biogas production, or put on gravel roads to reduce dust

Ethical Issues Human food? Solution: Use low grade seed
At Olds college, it costs $0.85/L to produce the biofuel (no profit made)
Less expensive to produce biofuel than to refine diesel from fossil fuels accounts for: costs of labour, extraction, land reclamation and oil refining

Ethical Issues Both biodiesel production and oil extraction have environmental impacts
It can be argued that impacts of biodiesel production are smaller than oil production impacts

Final NoteAs a society, we have to decide how much we are willing to pay ($) to reduce these impacts.•The products may change eg. Different material used for packaging, colour or other properties of the product may change slightly, etc.Concern: How will the consumer respond to these changes to their products
•Need to get producers on board with this movement
•Farmers could have to change their traditional ways of generating their product.

What is irrigation?
Irrigation is the artificial application of surface or ground water to promote plant growth.
It was first used by ancient Egyptians around 8000 BC.
In Alberta, we have explored four different irrigation systems, with many types of manipulations.
This includes Gravity Irrigation, Side Roll Irrigation, High Pressure Irrigation, and Low Pressure Irrigation.
In Japan, Gravity Irrigation or Flood Irrigation are used in the production of rice http://www.google.ca/imgres?q=ancient+irrigation&um=1&hl=en&sa=N&rls=com.microsoft:en-us&biw=1390&bih=821&tbm=isch&tbnid=A4Uuf1-

How much water is used for irrigation?
Alberta
• Irrigation accounts for 60-65% of all water consumption in Alberta (4.2 billion cubic meters)
• 98% is collected from the snowmelt, 2% is from glacial melt
Japan
• Agriculture uses nearly 60 billion cubic meters of water
• Extracted from rivers, water is channeled towards paddy fields

What are the current issues with irrigation?
• Unnecessary water diversion
• Runoff and leaching of pesticides
• Snowmelt occurring earlier
• Evaporation
• Improper application- to salty/sandy soil
• Overexpansion due to technology
• Ruts from pivots- water pooling

Common Pests
• Pests: Animal found in abundant numbers in an area it is not wanted
• In Alberta, the most common burrowing rodent animal pests on crop land are : I. Richardson’ ground squirrels
II. Pocket gophers
III. Voles (a.k.a field mice)
• Other pests include: IV. Skunks
V. Hares

I. Richardson’s Ground Squirrels
• AKA ‘gophers’, found in many areas throughout Alberta.
– Most common form of ground squirrel in the province.
– Major food source for badgers which can damage fields when digging for ground squirrels.
• Roles: important in local ecology , since they are part of the diet for a number of predatory animals such as badgers, and foxes.

II. Pocket Gophers
• They live in a burrow system that can cover an area of 18 to 185 square meters.
– are built for digging and tunneling with powerful shoulders.
– Also controlled by several natural predators from owl and hawks.
• Pocket Gophers eat stems and leaves in summer and spring, roots and other plant parts in fall and winter.

III. Voles (Mice)
• Voles tend to live when settlement and agriculture exist and agriculture exist and may give infested premises a distinct rodent smell.
– Climb about and under structures looking for food and places to habitat.
– They tend to chew, causing physical damage, as well as contaminate the areas they investigate with urine and feces.

IV. Skunks
• “striped skunk”, varies in length from 50-95cm, and similar in size to a house cat.
• Behavior:
– not a social animals, – eats both plants(flowers) and animals. – Adapt well to urban and rural areas, living under sidewalks,
decks, building and brush piles. – They stinks !!!!!

V. Hares
• Hares mainly live in the County of Strathcona, and prefer a habitat that contains dense stands of woody shrubs. – eat broad-leaf plants and grasses.
• When green vegetation is unavailable(winter), they will change to browsing on buds, bark and small twigs.
• Hares gnawing on the bark of woody plants can be a cause of plant mortality.

Problems: Richardson’s Ground Squirrels
• High population creates serious problems in our rural areas, they:
– Compete with livestock for forage
– Destroy food crops
– Weaken ditch banks (making them unsafe for farm machinery)
– Can damage haying machinery
• Population is naturally taken care of by predators but sometimes lethal control is necessary.

Forests of Jasper and Banff National Park
There are 3 major eco-regions that are found in Banff and Jasper National parks, they are; 1) Alpine this covers approximately 42% of
the landscape. This includes land above the tree line, which mostly consists of rock and ice.
2) Subalpine covers approximately 55% of the landscape. This area is above the valley but below the treeline. It includes sloped forests and meadows.
3) Montane covers 3% of the landscape, it is where most large animals occur, as well as most human use occurs. It is the valley bottoms, which provides the most productive habitats in the park.

Whitebark Pine
The whitebark pine tree grows in the cold subalpine eco region of the parks.
Is provides key ecosystem functions such as: reducing snowmelt by retaining snow, stabilizing soils, facilitates succession, and providing a food source to animals.

Special Concerns
Reduction in numbers due to:
Climate change
Fire exclusion
Mountain pine beetle
White pine blister rust brought from Europe in 1600’s
Efforts to mitigate the reduction include: Breeding programs to select for white pine blister rust
tolerant plants
Cages around cones to preserve seeds
Possibly presrcibed fire will open up the canopy

Mountain Pine Beetle
Mountain pine beetle is an invasive native species that can potentially have damaging effects on forests in Banff and Jasper National Parks.
The beetles target larger mature trees that have less sap. A younger healthy tree will be able to push the beetle out of the tree with sap.
The beetle eats through the bark and lays it’s eggs. When the eggs hatch, the larvae work into the phloem, then in a circular fashion around the phloem, producing a girdling effect which kills the tree.

Blue Stain Fungus
The mountain pine beetle also brings in with it a fungus called blue stain fungi. This fungi clogs the phloem which makes it harder for the tree to pitch the beetles out.
The fungi and beetle together cut off the flow of water and nutrients in the plants.

Mitigation of Mountain Pine Beetles
There are three forms of mitigation:
The main form of management of mountain pine beetles is fire. Fire helps produce younger and more varied vegetation that the beetles cannot easily attack, it also kills beetles in that area.
Infested trees can be cut and removed from the site. Thus eliminating the beetles present in that tree.
Pheromone baiting can also be used to concentrate beetles to certain areas of the park.

Vegetation Management
There are three different ways that forests and vegetation are managed in the parks;
Controlling non-native weeds
Re-vegetating disturbed areas with native plants
Prescribed Fires
![Page 111: Lowering the Carbon Footprint: Making More Sustainable in ... › wp-content › pdf › sites › 2 › ... · Presentation Outline Carbon footprint: the total amount of greenhouse](https://reader033.vdocuments.us/reader033/viewer/2022042400/5f0f463c7e708231d443590c/html5/thumbnails/111.jpg)
Non-native Weed Management
Non-native weeds are those that are not normally found in the area. These plants can be highly invasive as they often do not have any natural predators and can produce many seeds. They can reduce the ecological integrity of the parks.
In order to mitigate non-native weeds, Parks Canada has developed an integrated pest management program. This involves:
Mechanical controls - removal of weedy species by machine or hand.
Biological controls – removal of weeds by introducing natural predators.
Chemical controls – use herbicides to reduce amount of weeds to a level where mechanical removal is possible.

Why is fire necessary?
Old forests Grasslands
- More litter (logs, leaves, needles…) -Increased chance of uncontrolled fire -Closed canopy -Increased soil erosion -Lower biodiversity
-Mineral-rich ash -Open gap -High biodiversity
produce a mosaic of plant communities of different ages and species

Fire management
Monitor and evaluate progress
Fire controls - divide park forests into three different areas by human uses: Deep forest area… if a fire occurs, leave a fire and just watch
Middle area… leave a fire, but prevent to get into Human use area
Human use area… extinguish a fire immediately
Prescribed burn – a man-made fire used to burn an area in order to:
Restore ecological diversity, create a safe area, reduce fuel load, for scientific research, and to create food and habitat for wildlife.

Four Main Fire Adapted Species in Banff National Park
Douglas fir
Because of it’s thick bark, a fire that burns ¾
of it’s bark, will not be sufficient to kill the
Tree.
Aspen
Aspen grows from singular root
system, so it regenerates from roots
after fire.

Lodgepole pine
Lodgepole pine burns well.
its cones release seeds in fire, and
grow up rapidly after fire has occurred in
the area.
White spruce
White spruse also burns well,
it helps perpetuate fire, and allows
it to reach the forest canopy.

Poultry Breed Selection
Intensive systems:
• Low days until slaughter (41)
• Standard breeds, such as Ross or Cobb chickens
• Rapid weight gain required
• Heart attacks and leg problems due to rapid weight gain, making them unsuitable for organic systems

Organic systems: • Longer days before slaughter (81)
• Slow growing (do not have a feeding regime that pushes the bird to gain weight)
• Wide variety of breeds produce many flavours and varied feather colour
• Hardy nature to withstand outdoor exposure
• Sunshine Organic Farm: Feed organically raised grains grown on-farm

Pig Breed Selection Intensive systems: • Typically have animals confined on concrete flooring or
metal grating, so breeds with strong legs and feet are selected
• Breeding aimed at high performing, productive reproducers
• Major breeds in Canada: Yorkshire Landrace Duroc Hampshire Lacombe

Organic Farming
• The Organic farming method came from Europe.
• Organic farming was built on the concept of animal welfare.
• One concern with organic farming is disease, which may infect both humans and animals.
→And the fact that organic farming may impact domestic animal’s health.

Problems with Organic Farming
1. Organic farming requires great care.

Problems
1.Ethical problem The more and more farmer make Bio-ethanol productions
due to increase in prices of them. 2.Possibility to destruct environment Cultivation of Bio-ethanol productions is widely and rapidly
spread, which cause environmental destruction because of uncivilized cultivation and cutting trees.
3.Oxidization It has ability to oxidize metal. So it is difficult to use it entirely
with metal material such as car engines.

The most important things to achieve sustainability
① Cost This is mainly incentive for human. We have to balance between income and
