Two natural resources of Guyana
Forests
Gold
View source
Reasons why gold is important to Guyana
1. Can be used to create
jewelry
for domestic and international sale
2. Contributes to
GDP
through
exploitation
and
utilization
3. Provides employment opportunities for those involved in
mining
and processing
4. Can be used as a form of collateral for economic transactions
View source
The new road
Provided accessibility that contributed positively to the illegal tree harvesting trade
View source
The new environmental policy
Reduced the illegal tree harvesting trade
View source
It took 12 years for the illegal tree harvesting trade to return to the level that existed before the new road was built
View source
Natural resources should be conserved
Many are
non-renewable
and can be used up, so they can be
lost
for a very long period of time
View source
Waste reduction and minimization
Requires less
energy
to treat waste, and less land space for storage, thereby conserving
natural resources
View source
Measures to encourage industries to practice waste reduction and minimization
Tax break incentives
Implementation and
enforcement
of
proper waste disposal legislation
View source
Tax break incentives
β¨
Persuade industries to practice waste minimization by reducing their economic expenditure
View source
Enforcement of waste disposal legislation
Imposes economic
consequences
if the
legislation
is breached, persuading industries to comply
View source
Establishing an
independent
bodyβ¨
To monitor and account for
waste disposal
, without
bias
, to foster a culture of sustainability
View source
Sedimentation and siltation from
gravel extraction
and quarrying activities can result in significant
water pollution
View source
A series of
settling
points are used to reduce the total
suspended solid load
leaving the quarry
View source
Using the
ALARP
principleβ¨
Reducing components to the
least
amount reasonably practicable, to minimize
pollutants
discharged
View source
Country
B
β¨
Practices
consumptive
use of trees, as indicated by the
declining
tree density line
View source
Country B began practicing
consumptive
use of trees in
1984
View source
Rate of change
β¨
Using a
ruler
or straight edge to determine the
rate
of change between two points on a graph
View source
For the year
1985
, the value on the y-axis is approximately
2,900
trees per square kilometer
View source
For the year
1995
, the value on the y-axis is approximately
1,200
trees per square kilometer
View source
Calculating the rate of change
1. 2,900 - 1,200 =
1,700
trees per square kilometer
2.
1,700
trees / 10 years =
170
trees per square kilometer per
year
View source
Examples of consumptive use of natural resources (other than logging)
Fishing
Hunting
Mining
/quarrying/excavation
View source
Possible environmental impacts of hotel development on beaches
Increased
sedimentation
Increased
water
turbidity
Eutrophication
and algal blooms
View source
Sustainable yield management
Conservation approach associated with agriculture to minimize erosion and nutrient losses
View source
Use of substitutes for renewable resources
Associated with industrial activities to reduce
greenhouse
gas
emissions
View source
The measure that would apply to the proposed hotel development is the reduction and minimization of waste
View source
Sustainable yield management and use of substitutes for renewable resources do not apply to the proposed hotel development
View source
Renewable natural resources
Groundwater
Seagrass
beds
Beaches
Coral
reefs
Soils
View source
Non-renewable natural resources
Bauxite
Sand
Oil
Gravel
Gold
View source
Geographical factors affecting natural resource use
Location
, topography, latitude, climate
Influence extraction, quantity, and challenges
View source
Technological factors affecting natural resource use
Efficiency of extraction and processing machinery
Improvements over time enable more efficient use
View source
Population and
gravel extraction
both increased progressively from 1900 to
2000
View source
Population growth
Increase in gravel extraction
View source
Estimated gravel extraction in 2020 is approximately 5.2 thousand tons
View source
Settling ponds
Reduce particulate matter and dust in water from quarry sites
View source
Barriers/reforestation
Suppress dust and erosion around quarry sites after extraction
View source
Motivation of planting of trees in the periphery of the quarry zone
1. Even after quarrying mechanisms have been significant
2. Gravel extraction is associated with the removal of
vegetative
cover
3.
Re-establishment
of
reforestation
of particular vegetation types
4. To
suppress
the amount of
dust
or particles
5. To provide that level of cover
6. To reduce the amount further erosion on the quarried environments
View source
This is the last question for 2012 people, let us continue with 2013 paper unit 1 paper 2 module 3
View source
The policies of the country's government can significantly affect the use of natural resources by citizens
View source
Tax incentives
A policy implemented in 1978 that allowed a 100% tax refund on the cost of purchasing and installing solar water heating systems
View source
The graph shows the number of solar water heaters from 1974 to 1990
