Freshwater resource has been recognized as an economic good. Observed and projected climatic changes are likely to increase water stress in the future. Individuals and communities need to be prepared to minimise the negative impacts and maximise the benefits from changes. Autonomous adaptation such as maintaining water supply practices and restoring default or poorly maintained water facilities is supportive to increase adaptive capacity.
Insight of climate probabilities and knowledge of environmental consequences help building long term resilience to impacts. Continuation of research and assessment helps generating scientific knowledge which facilitates decision making for adaptation options. Development of human capital, strengthening institutional system and good management of public finances and natural resources are necessities for adaptation to future climatic changes.
Individuals and societies are already stressed by globalisation, urbanisation, environmental degradation, disease outbreaks and market uncertainties. Projected climatic changes and resulting water stress will intensify the condition. Increasing water supply, expansion of rainwater harvesting, restoration of aquatic habitats, improvement of water-use efficiency by water recycling are possible ways to increase resilience of people and ecosystem.
Integrated water resource management (IWRM) is a precise method to water management. IWRM aids planning adaptation instruments, co-ordinating land and water resource management, identifying water quality and quantity linkages, combined use of surface and ground water and protecting and restoring natural systems(Mathys, 2010).
