I think we should consider that there are climate change impacts in grondwater as well. The recharge rate is modified with the rain, evaporation (and evapotranspiration) conditions and with overland flow. This aspect should be incorporate in the introduction of this thematic forum. Take into account that groundwater is supply source for millons people, not only for livehood but economical and social development and ecosystems manteinance. Groundwater is an invisible resource that is affected by climate change in quantity and its quality.
The lack of consideration of this integrity of hydrological cycle has done that for decades the manage of water be concentrate only in engineering projects to drain water as soon as possible without consider the impact of this action in the soil, groundwater and of course the lowland of the basin. To achieve a change, it is neccesary that the develop of proffesionals and technicals includes this holistic vision. And of course it is neccesary to do a socializacion that what means water management to reach water security. These strategies are key to clarify the rols of civil society, communities and goverment.

Perhaps a theme that we should consider in this forum is the social vulnerability against the extreme climate events, which is its relation with both climate change and variability. How much is related to the first and how much to the later? How much of the risk it due to social vulnerability?
The manage of this problem should be faced as a whole, taking into account the uncertaninly and the fluctuation of hydrological conditions. A lot of regions in the world suffer repetely flood and drought, and the impact becames greater when social vulnerability is greater too.
Better tools and strategies to mitigate and/or adaptated to extreme hydrological conditions must be designed on the basis of the knowdledge and the good databases and information, that allows to understand the water cycle as a dynamic socio-ecohydrological system.

Dear Alexandre Gross, I think the great challenge to face the climatic variability and social vulnerability is both to improve the knowledge of the threats (climatic variability) by a better databases, information, approaches and analysis and, to develop capacities of people. This last one will allow that people take decisions on the basis of a good knowledge and they understand subjects such what place is more sure to live, why is it necessary to change some water use or how climatic change could affect groundwater recharge and then water supply of their city. I wonder if ordinary people know what means "water resources manage" in the daily practice and if they know that everyone has a responsibility as a manager of their own water use. Perhaps, these spaces like the Water Forum should promote this analysis and produce documents, message and recommendations about these themes. Otherwise, the Science will not be transferred neither government and to society.
