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.

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.

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.
