The Water Efficiency Paradox: The significance of spatial scale and knowledge exchange in irrigation water management

Water scarcity is a growing issue across the globe (Rijsberman, 2006) and because agriculture is the main consumer of water, investing in irrigation efficiency seems like a good solution to this problem. However, local gains in efficiency can reduce runoff and hence, have an adverse effect on downstream water availability (o.a. Perry (2018, 1999...

Water productivity assessment of rice paddies in Indonesia

IHE-Delft in cooperation with the Asian Development Bank (ADB) conducts a pilot project on assessing Crop Water Productivity in Asia, aiming to contribute to sustainable development in Asia’s irrigation sector, and create more value from scarce water resources. Indonesia is one of the 6 pilot countries where advanced technologies to measure...

Finding the Optimum Unsaturated Zone Storage Change Estimation Method to Improve Water Accounting in Vietnam

Evaluation of Two Automated Remote Sensing-Based Surface Energy Balance Models for Estimating Daily Evapotranspiration

Land and water use classification by means of spectral index based time series analysis

Currently available land and water use maps don’t meet the needs of hydrologists and water managers in many cases, particularly in developing countries. Existing maps often lack the resolution and detail required by hydrological models, and those that do meet requirements are limited in spatial coverage. The research presented in this report...

Bridging the Information Gap between Scientists and Decision Makers in the Eastern Nile

Scientific research is scarcely used for policy making (Hickey, Forest, Sandall, Lalor, & Keenan, 2013). The problem is as much a lack of communication of research results as a mismatch between the information produced by scientists and the information needed by the decision maker (Hickey et al., 2013; Timmerman, 2004). This information gap is a...

Comparative Analysis Among Near-Operational Evapotranspiration Products for the Nile Basin Based on Earth Observations

Following the success of open access rainfall products based on earth observation data, similar global products are now under development for actual evapotranspiration. In this research, seven prototype evapotranspiration products based on MODIS and geostationary satellites were compared for the Nile basin. They include the special MOD16 version...

Possibilities To Detect Supplementary Irrigation In Polder Areas With Remote Sensing

Whenever a piece of land is reclaimed for some reasons it becomes a polder. Polder areas by definition lie below the mean sea level and constitute special environments with respect to the prevailed wet conditions. In Netherlands, where the biggest part of the country is below the mean sea level, polders are common features of topography. Three...
