LARGE DAMS: Learning from the Past, Looking at the Future
4 Summary Report of the Workshop
INTRODUCTION
Something different and most promising happened
in Gland, Switzerland, in early April 1997. For two
days, 37 stakeholders, representing diverse interests
from around the world, explored whether they could
work together in seeking resolution of the highly con-
troversial issues associated with large dams. Given
more than two decades of increasingly acrimonious
exchanges about the development effectiveness of
large dams, most participants were not optimistic
about the outcome. But by the time they left Gland,
all had been surprised and excited by the breadth of
the consensus on how to move forward and the
issues to be addressed. Most notably, agreement was
reached on the next step: A World Commission
should be established to assess experience with large
dams and to propose if and how they can contribute
to sustainable development. All those present in
Gland committed to making the commission a reality
within six months and to seeking a mandate for it to
report within two years.
In Part I, this monograph summarizes what hap-
pened in advance of the workshop, during the two
days of discussions and immediately following the
workshop’s conclusion. In drafting the proceedings,
we have attempted to capture what was new and dif-
ferent about the Gland workshop and to identify the
implications for how to build on the initial consensus
and sustain its momentum. Part II contains the full
text of three overview papers that were commis-
sioned and two others that were reproduced to
inform the discussions.
1.0 THE WORKSHOP: ORIGINS,
PLANNING AND PROCEEDINGS
1.1 GROWTH OF CONTROVERSY
Dams have played a key role in development since
at least the third millennium B.C., when the first
great civilizations evolved on major rivers, such as
the Nile, Tigres-Euphrates and Indus. From these
early times, dams were built to supply water, control
floods, irrigate agriculture and provide for navigation.
More recently, since the onset of the industrial revo-
lution in the 18th century, they have also been built
to produce motive power and electricity. In the 20th
century, new technologies have made possible the
construction of increasingly large dams to meet vari-
ous mixes of these purposes; the 221-meter-high
Hoover Dam, inaugurated in the United States in
1935, ushered in a new era of big dams. In the last
half of this century, construction around the world
accelerated, with some 35,000 large dams being built
between 1950 and the late 1980s (International
Commission on Large Dams, 1988), the largest of
which, Nurek in Tajikistan, reached 300 meters high
(International Water Power and Dam Construction
Handbook, 1995).
However, there has been mounting controversy,
particularly over the last two decades, about the role
of large dams in development (Goldsmith and
Hildyard, 1984; McCully, 1996). As development pri-
orities changed and experience accumulated with the
construction and operation of large dams around the
world, various groups argued that expected economic
benefits were not being produced and that major
environmental, economic and social costs were not
being taken into account. In the 1980s proposals for
large dams began to be fundamentally questioned by
locally affected interests and global coalitions of envi-
ronmental and human rights groups (for example,
Sardar Sarovar). In the 1990s this has resulted in a
succession of calls for a moratorium on World Bank
funding and reparations for those affected by con-
struction of large dams (for example, the 1994
Manibeli and 1997 Curitiba Declarations).
1.2 WORLD BANK REVIEW
When he was appointed president of the World
Bank in 1995, James Wolfensohn announced his
intention to undertake a review of its development
effectiveness. Although it had been involved in the
financing of a relatively small proportion of the large
dams, the World Bank Group had become a major
focus of criticism because of the number of problem-
atic projects, including some of the biggest and most
controversial, in which it was involved. It was in this
context that the independent Operations Evaluation
Department (OED) of the World Bank began a
review of large dam projects. The first phase was
designed to be an internal desk study of 50 large
dams assisted by the Bank and was completed by
OED in September 1996. The second phase was
planned to be a broader study, involving the collec-
tion of new data and participation by other stakehold-
ers, to evaluate the development effectiveness of
