“…Most water supply systems are well able to cope with the relatively small changes in mean temperature and precipitation that are projected to occur in the decades ahead, except at the margin where a change in the mean requires a change in the system design or the technology used; e.g., where reduced precipitation makes additional reservoirs necessary (Harman et al, 2005), or leads to saline intrusion into the lower reaches of a river, or requires new water treatment systems to remove salts. A recent example of adaptation is in southern Africa (Ruosteenoja et al 2003), where the city of Beira in Mozambique is already extending its 50 km pumping main a further 5 km inland to be certain of fresh water.…”

“…Reservoirs are acknowledged as an important part of the infrastructure in order to cope with climate change to secure water supply in the future (Bates et al, 2008). In many regions climate changes will reduce precipitation further and additional reservoirs are necessary (Harman et al, 2005).…”

Abstract. Since the report from IPCC on renewable energy (IPCC, 2012) was published; more studies on water consumption from hydropower have become available. The newly published studies do not, however, contribute to a more consistent picture on what the "true" water consumption from hydropower plants is. The dominant calculation method is the gross evaporation from the reservoirs divided by the annual power production, which appears to be an oversimplistic calculation method that possibly produces a biased picture of the water consumption of hydropower plants. This review paper shows that the water footprint of hydropower is used synonymously with water consumption, based on gross evaporation rates. This paper also documents and discusses several methodological problems when applying this simplified approach (gross evaporation divided by annual power production) for the estimation of water consumption from hydropower projects. A number of short-comings are identified, including the lack of clarity regarding the setting of proper system boundaries in space and time. The methodology of attributing the water losses to the various uses in multi-purpose reservoirs is not developed. Furthermore, a correct and fair methodology for handling water consumption in reservoirs based on natural lakes is needed, as it appears meaningless that all the evaporation losses from a close-to-natural lake should be attributed to the hydropower production. It also appears problematic that the concept is not related to the impact the water consumption will have on the local water resources, as high water consumption values might not be problematic per se. Finally, it appears to be a paradox that a reservoir might be accorded a very high water consumption/footprint and still be the most feasible measure to improve the availability of water in a region. We argue that reservoirs are not always the problem; rather they may contribute to the solution of the problems of water scarcity. The authors consider that an improved conceptual framework is needed in order to calculate the water footprint from hydropower projects in a more reasonable way.

In this piece we explore the interface between adaptation research and adaptation policy, planning, and investment. We ask, 'How is research on adaptation informing the nascent domain of adaptation policy and practice?' To inform this discussion, we extract a few of the more salient lessons from four different domains of adaptation research: risk assessment and impact response, social vulnerability and adaptive capacity, resilience, and the science of decision making and policy implementation. Through a few select case studies of adaptation planning, we explore the extent to which we see these lessons taking hold in adaptation practice. The cases reviewed suggest that there may be significant differences in the type of research that informs planning in more industrial contexts compared to the developing world. Risk assessment and cost/benefit analysis appear to dominate adaptation planning in the industrialized world, while insights concerning governance, the social and economic constraints to adaptation, and building systemic resilience are featured more in planning documents from the developing world. The focus on risk assessment and associated technological interventions in the industrialized world illustrates the difficulty of addressing underlying structural and cognitive barriers to change, as well as the policy implications of conceptualizing adaptation as an outcome rather than a dynamic process. More broadly, the challenge of adaptation now offers an opportunity for innovative and collaborative research in which networks of academics, policy makers, atrisk populations, and other stakeholders actively participate in understanding the process of adaptation, experimenting in responses to change and learning from that process. 
