A Seasonal Agricultural Drought Forecast System for Food-insecure ...

By: C. Funk; S. Shukla; G. Husak; A. McNally

Description: Climate Hazards Group, Department of Geography, University of California, Santa Barbara, CA, USA. The increasing food and water demands of East Africa's growing population are stressing the region's inconsistent water resources and rain-fed agriculture. More accurate seasonal agricultural drought forecasts for this region can inform better water and agropastoral management decisions, support optimal allocation of the region's water resources, and mitigat...

A New Method to Measure Bowen Ratios Using High Resolution Vertica...

By: A. Clulow; T. Euser; W. Luxemburg; M. Mengistu; C. Everson; W. Bastiaanssen

Description: Delft University of Technology, Water Resources Section, Stevinweg 1, 2628 CN Delft, the Netherlands. The Bowen ratio surface energy balance method is a relatively simple method to determine the latent heat flux and the actual land surface evaporation. Despite its simplicity, the Bowen ratio method is generally considered to be unreliable due to the use of two-level sensors that are installed by default in operational Bowen ratio systems. In this paper w...

A Regional Model to Predict the Distribution Patterns of Alpine Pe...

By: B. Ye; J. Li; J. Wu; J. Wang; Y. Sheng

Description: State Key Laboratory of Frozen Soil Engineering, Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences, Lanzhou 730000, China. A field investigation and measurement of ground temperatures in boreholes was carried out in the upper area of Shule River in the western part of the Qilianshan Mountains, in the northeast of the Qinghai-Tibetan Plateau in 2008. On the basis of this a sketchy distribution pattern of pe...

Integration of Vegetation Indices Into a Water Balance Model to Es...

By: M. P. González-dugo; F. L. M. Padilla; J. Domínguez; P. Gavilán

Description: IFAPA, Centro Alameda del Obispo, P.O. Box 3092, Córdoba, Spain. Vegetation indices (VIs) have been traditionally used for quantitative monitoring of vegetation. Remotely sensed radiometric measurements of visible and infrared solar energy, which is reflected or emitted by plant canopies, can be used to obtain rapid, non-destructive estimates of certain canopy attributes and parameters. One parameter of special interest for water management applications...

Water Resources Trends in Middle East and North Africa Towards 205...

By: M. F. P. Bierkens; W. W. Immerzeel; B. Debele; J. Hoogeveen; L. P. H. Van Beek; W. Terink; P. Droogers

Description: FutureWater, Wageningen, The Netherlands. Changes in water resources availability can be expected as consequences of climate change, population growth, economic development and environmental considerations. A two-stage modeling approach is used to explore the impact of these changes in the Middle East and North Africa (MENA) region. An advanced, physically based, distributed, hydrological model is applied to determine the internal and external renewable...
