Study Notes

Maps and Their Functions

Maps are used to identify locations, distance, area, and direction of a place.
A map shows the exact site of a place and its general situation relative to other areas.
Location can be expressed in terms of neighbouring countries, external land masses, and water bodies.
A place can also be located using astronomical grid references – parallels and meridians.

Distance

Maps can be used to measure the distance between places.
Distance is calculated by using the scale of the map.
Example: The air distance between Hawassa and Addis Ababa can be calculated using a map of Ethiopia.

Area

Maps can be used to calculate the size of a place, country, region, or continent.
Area is calculated by measuring the length and width of the given place on the map.
The measurements are then converted to ground distances using the scale of the map.

Direction

Maps can be used to identify the direction and bearing of any place on the map.
Direction is determined by referring to another place on the map.

Water Resources in Ethiopia

Ethiopia is known as the "Water Tower of East Africa" due to its high water-resource potential, ranking second in Africa after the Democratic Republic of Congo.

Water Challenges in Ethiopia

Droughts occur every 3 to 5 years in Ethiopia.
Rift Valley lakes like Lake Abijata and Lake Cheleklektu are disappearing or at risk of disappearance.
The volume and purity of Ethiopia's rivers are decreasing due to pollution from sewage, organic waste, and fertilizers.
The growing human population is increasing the demand for potable water.

National Strategy for Water Conservation and Management

The Federal government has adopted a national strategy to conserve and manage water resources in Ethiopia.
The strategy aims to:

Key Components of the National Strategy

Incorporate the cost and benefits of protecting watershed forests, wetlands, and key ecosystems into project planning.
Recognize the importance of natural ecosystems in regulating water quality and quantity.
Ensure environmental health hazards are considered in dam and irrigation system design.
Conduct detailed studies and environmental-impact assessments for introducing exotic species into water ecosystems.
Promote protection of water-body interfaces (e.g., lake shores, river banks, and wetlands).
Involve local water-resource users, particularly women and animal herders, in planning and decision-making.
Recycle wastewater when safe for health and the environment.
Promote artificial recharge of ground and surface water resources.
Implement effective water-management techniques at the farm level for improved irrigation scheme performance.
Provide technical and credit support to the private sector in water resource development activities.
