The World

The world faces an unprecedented crisis in water resources management, with profound implications for global food security, protection of human health, and maintenance of all ecosystems on Earth. Large uncertainties still plague quantitative assessments of climate change impacts and water resource management, but what is known for certain is that the climate is changing and that it will have an effect on water resources. Therefore, increased efforts will be needed to plan and manage water supplies in the future through increased monitoring and understanding of the interrelationships between population size, climate change, and water availability. The focus of water management is gradually shifting from developing new water sources to using existing water sources more effectively and efficiently. The world needs policy change in water management. Respect for water resources and their value is the starting point of deliberations. Governments have the essential water management function: to protect and allocate water resources to allow both individual and collective interests to benefit from water. Societies must also lead in understanding, provisioning for mitigating the impact of disasters, ranging from extreme droughts to unprecedented floods, caused by climate change and poor management of water and land. Public funds will likely remain the main source of water sectoral funding. It is up to governments to invest wisely to enhance the crucial role that water has for social and economic development in a country. Integrated water resource management strategy is accepted as a global model for achieving the objective of a sustainable water management system.

Potential Climate Change

Water reforms in Australia have been comparatively progressive, including the agreement to the National Water Initiative (2004) and the implementation of over 130 water-sharing plans. Most of these plans include processes for dealing with climate variability, but only a few incorporate processes for addressing potential climate change impacts. Approaches include the use of scenario planning to better understand water availability and use; rules for prioritising water use; and setting aside reserve allocations. Vietnam, on the other hand, has had the legislative mandate since 1999 to develop water-sharing plans but has yet to do so. Recent reforms have led to the preparation of the National Target Program for a Sustainable Water Sector (NTPSWS): the national strategic plan for water resource management. The approval of the NTPSWS by the Vietnamese Government may provide the right incentive to gather resources to commence planning. The approaches used in Australia for addressing climate variability and potential climate change impacts would be transferable in the Vietnam context. Success, however, is probably dependent on strengthening institutional arrangements of the Vietnam water sector that includes increasing awareness of the benefits of water-sharing planning for sustainable water resource management at both the agency and community levels.

Future Climate Change

<p class="emsd"><span lang="EN-GB">More than half of the world’s population currently lives in urban areas. The fastest growing megacities are occurring mainly in developing countries, where stresses on water systems already pose major challenges for governments and water utilities. Climate change is expected to further burden water resource management, putting at risk governments’ ability to guarantee secure supplies and sustainable development. In this study, the significance of assessing the implications of climate change on water resources in megacities as an important component of the adaptation process is explored. The Mexico City Metropolitan Area (MCMA), one of the largest cities in the world, is presented as a case study. The downscaled outputs of the General Circulation Model GFDLCM2a for the A1B and B1 gas emissions scenarios for the period 2046–2081 and a statistical model were used to simulate the likely impacts of climate change in water resources and domestic water demand. The results showed that an increase in temperature and changes in precipitation patterns could increase household water demand for both scenarios, between 0.8% and 6.3% in the MCMA. The future projections also estimated increases of 150% and 200% in events with rainfall intensity of more than 60 mm d<sup>-1</sup> and 70 mm d<sup>-1</sup> respectively, drawing attention to the critical impacts these changes may have on flood events. Despite the uncertainty of models projections, future climate change scenarios have proven to be a flexible guide to identify vulnerabilities of water resources and support strategic adaptation planning. In order to increase their adaptive capacity and resilience to the effects of an uncertain climate change, megacities should consider implementing an integrated water resources management approach that creates opportunities through adequate policies, new technologies, flexible frameworks and innovative actions. </span></p>
