Characterization of hydro-meteorological drought in Nepal Himalaya: a case of Karnali River Basin por Khatiwada, K.R., Pandey, Vishnu Prasad

“…Firstly, historical data for 34-years (1981–2014) from ten different stations were analyzed to compute following drought indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Reconnaissance Drought Index (RDI), Self-Calibrated Palmer Drought Severity Index (sc-PDSI), Standardized Streamflow Index (SFI), and Palmer Hydrological Drought Severity Index (PHDI). Among them, SPI is able to capture the drought duration and intensity fairly well with the others. …”

Managing Forests for Both Downstream and Downwind Water por Creed, I.F., Jones, J.A., Archer, E., Claassen, M., Ellison, D., McNulty, S.G., Noordwijk, M. van, Vira, B., Wei, X., Bishop, K., Blanco, J.A., Gush, M., Gyawali, D., Jobbágy, E., Lara, A., Little, C., Martin Ortega, J., Mukherji, A., Murdiyarso, D., Pol, P.O., Sullivan, C.A., Xu, J.

“…We assert that forests, from the tops of their canopies to the base of the soils in which trees are rooted, must be considered a key component in the complex temporal and spatial dimensions of the hydrologic cycle. While it is clear that forests influence both downstream and downwind water availability, their actual impact depends on where they are located and their processes affected by natural and anthropogenic conditions. …”

Calibrated Models for Major Crops and Cropping System using Existing Datasets in Morocco and Uzbekistan por Devkota, Krishna, Devkota Wasti, Mina Kumari

“…Agricultural Production Systems Simulator (APSIM) (Keating et al., 2003), Cropping Systems Simulator (CropSyst) (Stöckle et al., 2003), Decision Support System for Agro-technology Transfer (DSSAT) are the process-based major cropping system models, and Hydrus-1/2/3D (Šimůnek et al., 2013) is a major hydrological model. Simulation models have the potential to quantify the magnitude of crop yield gaps and determine its factors.…”
