Climate risk management for water in semi–arid regions
Background: New sources of hydroclimate information based on forecast models and observational data have the potential to greatly improve the management of water resources in semi-arid regions prone to drought. Better management of climate-related risks and opportunities requires both new methods to develop forecasts of drought indicators and river flow, as well as better strategies to incorpor...
متن کاملThe DSSAT cropping system model
The decision support system for agrotechnology transfer (DSSAT) has been in use for the last 15 years by researchers worldwide. This package incorporates models of 16 different crops with software that facilitates the evaluation and application of the crop models for different purposes. Over the last few years, it has become increasingly difficult to maintain the DSSAT crop models, partly due t...
متن کاملAssimilating in situ soil moisture measurements into the DSSAT-CSM using a Kalman filter
With the ability to monitor soil moisture in time comes the opportunity to develop ways to incorporate these measurements into predictive models, without compromising or overriding the model physics. The importance of soil moisture to the growth of crops is well understood and because of this it is recognized as one of the more important parts of crop modeling programs. This research focused on...
متن کاملEvaluation of meteorological, hydrological and groundwater resources indicators for drought monitoring and forecasting in a semi-arid climate
Drought as a natural phenomenon characterized by a significant decrease of water availability during a period of time and over a large area. In recent years, droughts and its frequent in arid and semi-arid regions like Iran on the one hand, and water demand has been rising on the other hand and, as a result, their impacts are being aggravated. Therefore, the meteorological and hydrological...
متن کاملAnalysis of Farms Performance Using Different Sources of Irrigation Water: A Case Study in a Semi-Arid Area
Improving production efficiency is the main objective of government action to avoid efficiency losses and to increase the income of farmers. The aim of this study was to analyze performance levels of farms in the irrigated perimeter of Tadla in Morocco, according to the source of irrigation water. Thus, technical, allocative and economic efficiency were analyzed for farms in this area. To estim...
