We present a dataset of 1010 entries of dams in South America describing several attributes such as the dams' names, characteristics, purposes, georeferenced locations and also relevant data on the dams' catchments. Information was obtained from extensive research through numerous sources and then validated individually. With this work we expect to contribute to the development of new research in the region, which to date has been limited to certain basins due to the absence of information.

In this paper we follow a user-based approach to examine operational drought management decisions and how the role of information on them can be assessed. The approach combines a stakeholder consultation and a decision model representing the interrelated decisions of the irrigation association and farmers. The decision model was extended to include information on snow cover from satellite. This contributed to better decisions in the simulation and ultimately higher benefits for the farmers.

We present a methodology for regional assessment of current and future water availability in Europe. The methodology is based on a proposed indicator of risk of water scarcity based on the projections of runoff and water availability for European countries. The water scarcity risk index is a global value that accounts for the results obtained with the ensemble of model results and emission scenarios.
