Namibia: Epupa Dam Study
Namibia: Epupa Dam Study

Region: Southern Africa
Issue Areas: +economy/development+
This posting contains a press release from the International Rivers Network
Southern Africa Program, featuring reviews by outside experts of the feasibility
study for the proposed Epupa Dam. The reviewers conclude that the study
is "woefully incomplete," and particularly stress that it leaves
out an accounting on the project's social impact on the Himba people of
the area. For additional reports on the controversial scheme, including
replies from the authors of the feasibility study and the opinions of local
communities, see the web site of The Namibian newspaper (http://www.namibian.com.na).
The paper has a special update section on the project (http://www.namibian.com.na/Netstories/Environ2-98/epupaupdate.html).

EPUPA DAM FEASIBILITY STUDY TOO POOR TO USE, EXPERTS SAY
The feasibility study for the proposed Epupa Dam in Namibia is so riddled
with incorrect conclusions, false assumptions and missing data that it
cannot be used as a basis for a well-informed decision on the project,
according to a group of outside experts who reviewed the massive report.
The reviews, which were filed on Monday with the Namibian government, clearly
indicate that the Epupa project has not been justified on economic, social,
environmental or power supply grounds.
The seven reviewers looked at sections of the report relevant to their
field of expertise, on behalf of the people who would be affected by the
dam. The review was coordinated by local and international nongovernmental
organizations, including International Rivers Network.
The Epupa Dam is expected to have a capacity of between 200 to 360 megawatts.
Its reservoir could inundate as much as 350 square kilometers of land,
forcibly displace up to 1,000 people and affect several thousand more.
The recently completed feasibility study cost US$7 million. It was funded
by Norwegian and Swedish aid agencies (NORAD and SIDA).
Reviewers found inadequacies in the study's sections on economics, environmental
impacts, hydrological assumptions and alternative energy analysis. But
the most serious problem is that the study leaves out an accounting of
the project's social impacts. The dam would have potentially devastating
impacts on the pastoralist Himba, who have lived in the area for centuries.
At the same time the reviews were filed, 26 of the 32 Himba chiefs in Epupa
area stated publicly that they oppose the project.
Reviewer Sidney Harring, a Professor of Law at City University of New
York and former Fulbright fellow in Namibia, says:
"There should be no public hearings at all on this woefully incomplete
report. Large scale dams are no longer simply engineering matters: the
human and environmental impacts are fundamental and must be given full
weight. Since this information was not included in the study, the study
should not be used further, in any context, until it is complete."
The feasibility study also describes the controversial project as the
"least-cost" option for Namibia's growing energy needs - an assertion
that reviewers found to be based on false assumptions of cost estimates
for both Epupa and alternatives to the dam. Steven Rivkin, a professor
of economics at Amherst College, says the project will be an economic loser,
contrary to the report's assertions. Rivkin says:
"I do not believe that this dam project passes the narrow test
of economic viability using only the quantifiable costs and benefits, much
less so when all costs and benefits are considered. I strongly recommend
that this project not be undertaken."
The reviews, by experts in the fields of hydrology, freshwater ecology,
economics, international law and alternative energy, were submitted to
the government as background for a public hearing on the project and the
feasibility study, scheduled for February 7 in Windhoek, Namibia.

The feasibility study is also available on the web, but it takes a long
time to download and requires "unzipping." The study can be found
Below is a summary of some of the reviewers most important findings.
- The dam offers Namibia the least flexibility and the most risk compared
to other energy options. Because the project is very risky and permanent
and a large percent of Namibia's total investment, the required rate of
return (discount rate) is almost certainly much higher than the rate used
in the study (10%). A higher, more realistic rate makes the project economically
unviable, even if all non-quantifiable costs are ignored.
- Both electricity demand and future power costs seem overestimated in
the study. These questionable estimates raise serious questions about the
- Non-quantifiable impacts are downplayed. The fact that this project
would permanently eliminate the homeland for the Himba people and the precious
natural resource of Epupa Falls reduces further the likelihood that this
project will benefit the people of Namibia.
Social Impacts Ignored
- The Feasibility study is so incomplete that any scheduling of public
hearings is premature: none of the project's social issues can be adequately
addressed in hearings until a full social mitigation study is completed.
- The study does not include the elaborate program of study, consultation,
careful scoping of potential negative impacts on affected people's lives,
nor a social mitigation program, that is required by international law
and recognized professional standards.
- The scant information on the social impacts trivializes the Himba culture
and economy, minimizes the project's impacts on the Himba way of life,
glosses over the Himba's land- and water-rights, and offers a glib assessment
of resettlement costs.
Alternative Energy Costs Misrepresented
- Contrary to claims in the Feasibility Study, the dam is not the least
cost energy alternative for Namibia. The cost of energy from a combined
cycle gas power plant would be 40% cheaper than electricity from Epupa.
The study also misrepresented the costs of energy from the Kudu gas fields,
now under development.
- The consultant inappropriately uses assumptions in the analysis that
underestimate the viability of alternative energy sources. For example,
using conventional assumptions about solar electric systems would result
in approximately 20 percent lower costs than what the study indicates.
- The study's assumption that wind power would require 20 years to develop
is greatly exaggerated. Wind power could make a substantial contribution
to Namibia's energy portfolio by the year 2005.
Hydrological Data Poor
- The analysis is based on scant hydrological data (a meager 12-year
stream flow record from a location 200 km upstream of the dam site), and
does not take into account changing hydrological conditions. Changes in
the study's hydrological analysis could make this project an economic burden
on the country.
Environmental Impacts Downplayed
- The authors downplay the impacts of the reservoir's high rate of water
evaporation. Evaporation losses from the Epupa reservoir would in fact
amount to many times Namibia's total urban consumption. The authors say
"the external costs of evaporative losses must be set at nil due to
a lack of alternative uses for this water." Setting the value of a
natural resource at zero just because it has not been utilized disregards
all future possibilities and needs. Considering that Namibia has an ever-increasing
water shortage problem, the Cunene represents a priceless water reserve.
The dam's huge evaporation loss and the desperate need for water in Namibia
alone should conclusively eliminate any proposal to build this dam.
- The report recommends a "minimum flow" for the river below
the dam site during the construction (which will last years) that is not
based on a full analysis of the river's ecology and water requirements
(called Instream Flow Requirements, or IFR). It is unacceptable that flow
recommendations were made in the absence of an IFR study.
