This research assesses present (2009-2016) and future (until 2100) levels of water security taking into consideration socioeconomic and climate change scenarios using the WEAP (Water Evaluation and Planning) tool for Semidistributed hydrological modeling. The study area covers the VilcanotaUrubamba basin in the southern Peruvian Andes and presents a complex water demand context as a glacier-fed system. This study also further explores the importance of incorporating science and policy within a broader study of water security. As a result, it is expected to deliver high spatial resolution water demand maps and adaptation strategies for stakeholders. This research is part of the RAHU project as a new multidisciplinary collaboration between UK and Peruvian scientists.

Water is an essential resource for social and economic development. The availability of this resource is constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- (2017–2040), middle- (2041–2070), and long-term (2071–2099) levels of water security considering socio-economic and climate change scenarios using the Water Evaluation and Planning System (WEAP) in Vilcanota-Urubamba (VUB) catchment. The streamflow data of the Pisac hydrometric station were used to calibrate (1987–2006) and validate (2007–2016) the WEAP Model applied to the VUB region. The Nash Sutcliffe efficiency values were 0.60 and 0.84 for calibration and validation, respectively. Different scenarios were generated for socio-economic factors (population growth and increased irrigation efficiency) and the impact of climate change to evaluate their effect on the...

El presente catálogo describe la organización de las actividades de la SEH, considerando en primer lugar las líneas de investigación del SENAMHI que fueron establecidas tomando en cuenta las políticas públicas, luego se considera la definición de la Organización Meteorológica Mundial respecto a que los Servicios Hidrológicos deben desarrollar ciencia aplicada que contribuya con bases sólidas para la hidrología operacional y que esté enmarcado dentro de la cadena de valor Hidrológica. Este catálogo presenta 13 productos desarrollados en el período 2021-2025, cada producto contiene plataforma de visualización web de libre acceso que contribuye a la toma de decisión informada de utilidad para la Gestión de Riesgos de Desastres, Gestión Integrada de los Recursos Hídricos y Medidas de Adaptación frente al Cambio Climático. De estos 13 productos, 4 abarcan todo el territ...

The Peruvian Andes are a hotspot of vulnerabilities to impacts in water resources due to the propensity for water stress, the highly unpredictable weather, the sensitivity of glaciers, and the socio-economic vulnerability of its population. In this context, we selected the Vilcanota-Urubamba catchment in Southern Peru for addressing these challenges aiming at our objectives within a particular hydrological high-mountain context in the tropical Andes: a) Develop a fully-distributed, physically-based glacier surface energy balance model that allows for a realistic representation of glacier dynamics in glacier melt projections; b) Design and implement a glacio-hydrological monitoring and data collection approach to quantify non-glacial contributions to water resources and the impact of catchments interventions; c) Mapping of human water use at high spatiotemporal resolution and determining ...
