Data collection design for calibration of crop models using practical identifiability analysis
The collection of high-quality calibration data is essential for the estimation of parameter values and reliability of crop models. However, few tools are available to quantify the minimum number of observations needed for parameter estimation. We therefore here applied practical identifiability analysis, based on global sensitivity analysis, to de...

Water productivity of potato under improved irrigation techniques in Uzbekistan [Abstract only].
Potato is a very important cash crop in Uzbekistan as the government has implemented several measures to increase its production to meet food security as well as to improve its export potential. However, irrigation water demand of potato is much higher than for other crops such as sorghum and maize, which normally consume less water and generate mo...

Evaluation of Crop Models for Simulating and Optimizing Deficit Irrigation Systems in Arid and Semi-arid Countries Under...
Published in Water Resources Management
The variability of fresh water availability in arid and semi-arid countries poses a serious challenge to farmers to cope with when depending on irrigation for crop growing. This has shifted the focus onto improving irrigation management and water productivity (WP) through controlled deficit irrigation (DI). DI can be conceived as a strategy to deal...
Assessment of the quality of meta-analysis in agronomy
A meta-analysis is a statistical treatment of a dataset derived from a literature review. Meta-analysis appears to be a promising approach in agricultural and environmental sciences, but its implementation requires special care. We assessed the quality of the meta-analyses carried out in agronomy, with the intent to formulate recommendations, and w...
Water for irrigation or hydropower generation?Complex questions regarding water allocation in Tanzania
The need for achieving efficient, equitable and sustainable use of water resources to meet water demands of different sectors is pressing, particularly in areas where water resources are dwindling. Along with this is the quest for having a good understanding of the value of water in its different uses. Using a simplified model derived from the resi...
