2ND OPPORTUNITY
QUESTION 1. WATER AND WETLANDS AWARENESS
1.1 You have been invited to give a presentation to Grade 9 learners from Walvis Bay High (14)
School on the Kuiseb River as a linear oasis and as a water supply source. Based on what
you know and experienced on your excursion to the lower Kuiseb River Basin, prepare a
suitable, 7 slide presentation. Emphasize the ecological and the ecqnomic value of the
lower Kuiseb River to the wildlife and people that live alongside it, as well as to the town
of Walvis Bay. Explain who is responsible for water supply from the Kuiseb River give
three challenges to that the water suppliers face. End by inviting the learners to join
you on a visit to the NamWater boreholes, the High Dune Reservoir and to the Gobabeb
Namib Research Institute as you want to further explain and demonstrate the value of
this linear oasis and the challenges of water supply. Your last slide must show a map of
the route you will take for your one-day excursion.
1.2 Write a short newspaper article for the Namib Times to tell readers about the link
(10)
between unconventional water sources, and the limited water supplies from
conventional water sources, at the coast. Explain how this could be the solution to
managing water supply in the arid, central coastal region. Base your article on your visit
to the Erongo Desalination Plant and your interviews with NamWater officials during
your coastal excursion. Give your article a catchy title, describe the photograph you will
use and provide a suitable caption.
(24)
QUESTION 2. WATER AND WETLANDS CONSERVATION - RAMSAR
2.1 Choose either: A. The Bwabwata Okavango Ramsar Site,
(10)
or
B. The Walvis Bay Wetlands Ramsar Site
Use the attached Ramsar Criteria for wetlands of international importance to draw a
table to briefly sum up 5 criteria it meets and to clearly motivate why.
2.2 What is this year's theme for World Wetlands Day. Describe the three activities you did (8)
with learners from Groot Aub during the visit to Avis Dam, clearly link each activity to
either, this year's theme, or the value of a heathy wetland. Finally add which one of
your activities was not really suited to the wetland type at Avis Dam and why.
(18)
QUESTION 3. BIOMONITORING
3.1 What does SASSstand for? and clearly explain why we use aquatic invertebrates to
(3)
determine river health.
3.2 The geography teacher at Rundu High School wants her Grade 12 learners to compare
(6)
the health of the Okavango River upstream and downstream of Rundu Beach because
she is worried about pollution from people swimming and washing their cars in the river.
She has asked you as the OkBMC Basin Officer to tell her about a simple method she
can use to monitor the quality of the water. Write to tell her about Mini SASS,how it
works, and what equipment she will need. Explain why the method is suitable for
learners to use. Explain what data sheets and identification guides are available. Offer to
assist her the first time and suggest how often they should sample.
3.3 Draw a table to compare three differences between SASS4 and Mini-SASS 2.

QUESTION 4. NATIONAL-LEVEL WATER RESOURCESMANAGEMENT
The Water Resources Management Act 11 of 2013 advocates River Basin Management
as the most appropriate way to manage our water resources in Namibia. The central
Namib Water Region falls under two different River Basin Management Committees
4.1 Name and give the correct abbreviation for the two River Basin Management
(4)
Committees active in the Namib Water Region.
4.2 Based on the guest presentation by Mr. Ignatius Sikongo, Basin Support Officer for the (6)
Kuiseb Basin, list six responsibilities of National River Basin Management Committees, as
mandated by the Water Resources Management Act 11 of 2013.
4.3 Based on your visit to the Omdel scheme and the lecture on water supply from
(6)
ephemeral rivers and the Omdel scheme as a case study, draw a simple sketch to show
the layout of the scheme. Add short labels and arrows to explain the process.
4.4 Based your excursion to the coast this year, discuss three Water Demand Management (6)
methods we use in Namibia that other countries in the world can adopt to help them to
use water more efficiently to better cope with decreasing water availability due to
climate change and increasing water demands.
[22)
QUESTION 5. INTERNATIONAL-LEVEL RIVER BASIN MANAGEMENT
In 2010, OKACOM, commissioned an Environmental Flows Assessment in all three countries
that share the Okavango River Basin. This research was led by Dr Jackie King, who won the
Stockholm Water Prize for her studies on Environmental flows, as an aid to river basin planning.
Based on what you have read and learnt about this study answer the following questions.
5.1 Give the full name of OKACOM and name the two countries that share this basin with
(3)
Namibia.
5.2 Sketch a typical hydrograph, for the Okavango River at Rundu to show the four stages
(6)
for the flood-pulsed Okavango River.
5.3 Briefly outline the process that was followed to assessfuture impacts on environmental (6)
flows throughout the basin,
5.4 Use the attached handout of the main findings of the OKACOM EFAto interpret the total (5)
livelihoods graph for each of the three scenarios, Low, Medium and High. Link this to
the three pillars of sustainable development: social equity, environmental health, and
economic wealth, to explain which pillar of sustainability will be most clearly affected
and why.
[20)
QUESTION 6. INTEGRATED WATER RESOURCESMANAGEMENT
6.1 IWRM is based on the principles agreed on at the International Conference on Water
(8)
and the Environment held in Dublin, Ireland in January 1992.
List four of the Dublin Principles and give an example of how each is met in the water
management in any Namibian river basin of your choice.

6.2 Write a short essay on IWRM in the Namibian river basin that you prepared a poster on. (16)
Give a brief introduction to describe your river basin, giving its locality, the mean annual
rainfall, when it rains, important wetlands and aquifers in the basin and the main human
activities dependent on water supplies in the basin.
Then choose two of the points below and write a paragraph on each to show these
IWRM links within your basin:
• The inter-relationship of upstream and downstream sections of the basin
• The joint use of both surface and groundwater sources
• Co-operation and sharing between different water suppliers and users.
• Water conservation to ensure enough water for both the Environment and people.
Finally conclude with what you see as the main advantage of IWRM to Namibia and
motivate your answer.
