Ranju Chapagain is a PhD Researcher at University of Tasmania. Her research interest is within the field of agriculture, water resources, climate change impact and adaptation and model uncertainty. She is currently undertaking PhD project at Tasmanian Institute of Agriculture in collaboration with Agriculture & Food unit at CSIRO for assessing and decomposing crop model uncertainty using wheat and potato as reference crops at regional (Tasmania) scale and national scale.

Crop models are essential tools for analysing the effects of climate variability, change on crop growth and development and the potential impact of adaptation strategies. Despite their increasing usage, crop model estimations have implicit uncertainties which are difficult to classify and quantify. Failure to address these uncertainties may result...
Northeast Thailand makes a significant contribution to fragrant and high-quality rice consumed within Thailand and exported to other countries. The majority of rice is produced in rainfed conditions while irrigation water is supplied to rice growers in the dry season. This paper quantifies the potential impact of climate change on the water footpri...
Conference Paper
Climate change impact on rice yield and its corresponding water footprint was investigated for a case study in Northeast of Thailand. CERES-Rice crop growth model was used to simulate rice production which was set up and validated using yield data during 2009-2013. Three different rice varieties (KDML 105, RD 6 and ChaiNat-1) were considered in the...
Climate change and global warming pose a significant threat to agriculture and global water security. The research investigates the effects of climate change on water footprint on rice production on Nam Oon Irrigation Project in Sakon Nakhon province of Thailand. Three rice cultivars, KDML 105, RD6 and ChaiNat-1, were considered in this study. KDML...

Estimating Crop Model Uncertainty in Agricultural Systems
Research questions -What are the dominant sources of crop model uncertainty in model predictions? -How much weight does each uncertainty source contribute to the total uncertainty? -Which key gaps exist in understanding, characterising, and assessing crop model uncertainty? -Which are possible ways to reduce crop model uncertainty?
The goal of the project is develop improve methods to characterize the meteo-hydrological processes into simple, robust manner that can be easily integrated into operational forecasting. For the study area, the Terai region of Nepal is selected. This region is affected by floods almost every year and this research would give some new lights in terms of flood prediction in Nepal.
