l51 OPPORTUNITY EXAM JUNE
QUESTION 1. WETLANDS AWARENESS
1.1 Groot Aub Primary school has asked you to prepare a 6-slide presentation for Grade 6
(12)
learners for their World Wetland Day celebration this year. They have asked you to link
it to this year's theme for World Wetland Day and to the visit you plan to do with the
learners to Avis Dam after your presentation. The presentation should make them
aware of the plants and animals supported by the dam and the Klein Windhoek River,
the social value of Avis Dam to the citizens of Windhoek, as well as any threats to these
wetlands. Conclude with practical activities the learners themselves can do to help to
reduce the impacts of these threats. Ensure that your title slide is eye-catching, your
presentation is well-illustrated and has a clear message for action.
1.2 Based on your kayaking and bird counting experience at the coast this year, prepare a
(9)
short newspaper article (max 250 words) for a tourist supplement in "The Namibian" on
wetland-based tourism. Showcase the value of the Walvis Bay Ramsar Site as both an
adventure sport and bird watching destination. Also provide positive guidelines on how
tourists can help prevent unnecessary disturbance when visiting these wetlands to
conserve their rich biodiversity. Have a catchy title, Describe the photograph that you
will use to illustrate your article and give its caption.
1.3 Clearly distinguish between lotic and lentic wetlands.
(2)
1.4 Clearly distinguish between lacustrine and palustrine wetlands.
(2)
[25]
QUESTION 2 WETLANDS CONSERVATION - RAMSAR
2.1 Choose either A or B
(10)
A. The Etosha Pan Ramsar site at the bottom end of the Cuvelai System
B. The lishana section of the Cuvelai System as a potential Ramsar Site
Use the attached Ramsar Criteria, to draw up a table to clearly show how the site you
choose meets five of the Ramsar Criteria. (Provide a brief description of each criterion).
2.2 Briefly explain what the Montreux Record is, name the Namibian Ramsar Site currently
(4)
on this list, and give two reasons why it is on the list.
[14]
QUESTION 3. WATER RESOUCES MANAGEMENT IN NAMIBIA
3.1 Write a paragraph to explain what is meant by Water Demand Management, give six (6) (8)
examples of how this is done in Namibia and conclude with why implementing WDM is
important in Namibia.
3.2 Based on your practical in the Fish River below the Hardap Dam, say what SASSstands
(2)
for, and explain why we use aquatic invertebrates to determine river health.
3.3 Give examples of Mini-SASS groups you found in the Fish River:
(5)
A. One with a high score, B. Two with medium scores and C. Two with low scores.
3.4 Name the aquatic mammal that we identified from the scats we found at the site where (1)
we did our mini-SASS survey in the Fish River.

QUESTION 4. INTEGRATED WATER SUPPLY AND MANAGEMENT IN THE CENTRAL NAMIB AREA
Based on what you learnt on your excursion to the coast, write an essay on water supply (24)
to the Central Region from the alluvial aquifers in the Kuiseb and Omaruru rivers and the
challenges the bulk water suppliers face when trying to ensure an adequate, good
quality water supply to the users in such an arid, yet rapidly developing, area. Be sure to
give accurate facts and figures. Also explain how the water suppliers make use of
unconventional water sources to meet the growing demand, discuss the challenges
related to making use of these unconventional water sources and give the reasons for
the increase in water demand in the central coastal area. Conclude by suggesting an
additional effective WDM strategy, that the municipalities of the coastal towns should
consider implementing.
[24]
QUESTION 5. INTERNATIONAL- LEVELRIVER BASIN MANAGEMENT
At international-level river basin management is the task of River Basin Management
Commissions, like the Permanent Okavango River Basin Commission OKACOM.
5.1 Read the attached handout of the main findings of the OKACOM EFA,and interpret the (8)
main overall results shown in the mean annual runoff graphs, schematic maps, and the
total livelihoods graph across the three, water use and development scenarios tested,
(Low, Medium, and High), and say where the greatest impacts will be.
5.2 Write a paragraph to discuss a new threat identified to the Okavango River System, by (8)
the National Geographic team that have monitored the basin since the OKACOM EFA
study and say what impact, this threat will have in each of the riparian countries and
internationally.
[16]
QUESTION 6 INTEGRATED WATER RESOURCESMANAGEMENT
Write an essay on IWRM in the Namibian River Basin unit that you prepared a poster on. (25)
As an introduction briefly describe your river basin, where it is, the mean annual
rainfall, variability in rainfall, the types of wetlands and aquifers found there, and the
main activities or land uses in the basin.
Choose three of the points below and write a paragraph on each to show Integrated
Water Resources Management links within your basin:
• The joint use of both surface and groundwater sources
• Use of both conventional and unconventional water sources
• Co-operation and sharing between different water suppliers and users.
• Water conservation to ensure enough water for both the Environment and people.
• Cooperation between countries that share the same River Basin
Finally conclude with two main advantages of IWRM to Namibia.
