. Challenges and opportunities in water resources –
Role of hydrological modelling, remote sensing and geographical information system
The growing population, urbanization, and economic development, particularly in Asian Countries, is keeping the food demand high, and putting enormous pressure on limited land and water resources available. Water managers are increasingly faced with multi-criteria, multi-objective and multi-constraint decision making to assess and improve land and water management in their regions. They need to make environmental, economical and social-cultural considerations in assessing their decisions, plans and policy formulations. All this requires a good understanding and quantification of different water sources and demands, and evalation of potential impacts of planned management activities on land and water productivity and its sustainability.
Reflecting on the challenges faced in water resource management, this paper will present integrated applications of hydrologic models, remote sensing and sophisticated computational tools such as Geographical Information System to improve land and water management. In particular, case study examples will be presented to evaluate the performance of current and alternative water management options for irrigation systems in northern India, for subsurface drainage management in Midwestern United States, and for water resource planning and management in Western Sydney Australia. The paper will conclude demonstrating that advances in hydrological modelling, remote sensing and GIS are providing new opportunities to develop time efficient and cost-effective tools to understand and quantify different components of complex hydrological and agricultural production systems, and help assess options for future improved land and water management.
Dr. Ranvir Singh is currently working as Senior Lecturer in Environmental Hydrology and Soil Science at the Institute of Agriculture and Environment, Massey University, Palmerston North, New Zealand. In 1999 he graduated with Master of Technology in Soil and Water Engineering from CCS Haryana Agricultural University (Hisar), India and then earned his PhD in Environmental Sciences in 2005 from Wageningen University and Research Center, The Netherlands. Following his studies, he worked as a Postdoctoral Research Associate in a Targeted Watershed Program at Iowa State University (Ames), United States, and then as a Research Fellow in the CRC for Irrigation Futures at University of Western Sydney, Australia. His research involves development and applications of hydrological models, remote sensing and GIS information for improved land and water management. He has been actively engaged in research projects developing and applying hydrologic models for agricultural water productivity analysis, subsurface drainage and its management, and water cycle planning and management in peri-urban landscape
