Introduction
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.

Introduction
Soil type plays a major role in nutrient dynamics and soil water which impacts crop growth and yield. The influence of soil characteristics on crop growth is usually evaluated through field experimentation (in the short term) and through crop-soil modelling (in the long-term). However, there has been limited research which has looked a...
The three major sources of uncertainty in crop models are model inputs, structure and parameters. Model structure is one of the major contributors to this uncertainty, however, its quantification is difficult due to limitations in controlling confounding effects from parameter and input uncertainty. The objective of this study was to quantify the c...
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...
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...
