My name is Sanjeewa Illangasingha from Sri Lanka. I work at Mahaweli Authority of Sri Lanka which is the largest multi-disciplinary government organization related to water related in Sri Lanka. My research is to investigate the utilization of water resources of the Mahaweli and its main adjacent basins (Kalani, Deduru Oya, Maduru Oya, Yan Oya, Kala Oya, Malwatu Oya basins) in Sri Lanka including the climate change adaptation and resilience strategies for optimizing benefits to the study regions. Several stakeholders are available for use of Mahaweli water within the basin and adjacent basins. Demands for drinking water, irrigation water, and industrial water are increasing day by day. It was observed that fulfilling the required demand of Mahaweli water is uncertain in some seasons while flooding downstream. During some seasons, there is more water of Mahaweli and the adjacent basin is flowing to the sea without having significant use. The further disputed tradeoff between hydropower and irrigated agriculture can be seen in the Mahaweli and main adjacent basins during some seasons. This may have occurred because of the Climate Change impacts, along with ineffective water management practices, unavailability of updated reservoir operation rules, and increasing demands, etc. There is a lack of a proper framework to address these issues due to the gaps in science and technology among the main stakeholders. Therefore, it is important to identify the future water resources deviation trends of Mahaweli and its main adjacent basins for preparing new policies to overcome the above matters. There may be different solutions or ways for utilization of water resources of Mahaweli and its main adjacent basins with an integrated approach to have stable food, water, and energy nexus. Some may be costly as well as causes for environmental and sociological problems. Water related Organizations in Sri Lanka are facing financial limitations for the relevant studies, thus optimum use of open and free software are so important and sustainable as well. Advance science and technology based solutions would be more feasible for having a sustainable policy framework.
