    Anticipation, significance and response to ecosystem impacts of large dams
    (2000) Clarke, Christopher; Khagram, Sanjeev; Aylward, Bruce
    This paper provides a brief overview of the context, scope, methodology and salient findings emerging from a survey of 125 large dams in 52 countries world-wide. This global Cross-Check Survey was one of four key work programme components integral to the world Commission on Dams, initiated in Gland, Switzerland in 1997. In particular the paper gives a brief overview of some of the key issues responsible for significant ecosystem impacts and highlights key responses practices in a variety of different regions and countries world-wide.

    Cross check survey : World Commission on Dams
    (2000) Clarke, Christopher; Aylward, Bruce
    The World Commission on Dams (WCD) has completed a global survey of the performance, impacts and decision-making aspects of 125 large dam projects - th Cross-Check Survey. The primary aim of the Survey was to determine broad patterns and trends indicative of past performance, impacts and decision-making aspects of a selection of large dams that reflect the global population. Consequently, the findings of the Survey provided a link between the broad patterns and trends emerging at a global and regional level and the more in-depth findings provided by the other components of the WCD knowledge base. Thus, the Survey provided an entry point to "cross-check" the collective evidence to the WCD knowledge base - comprised of over 900 topic-related written submission, four regional consultations and workshops, 17 thematic reviews, 11 case studies and three country studies. The Cross-Check Survey sought to inform the WCD knowledge base on large dams in a responsible and consequential way but without any claims for being necessarily complete.
