Water is the primary medium through which climate change will impact people, ecosystems and economies. Water resources management should therefore be an early focus for adaptation to climate change. It does not hold all of the answers to adaptation; a broad range of responses will be needed. But water is both part of the problem and an important part of the solution. It is a good place to start.Globally, the overall impacts of climate change on freshwater resources are expected to be negative. But there is much that is not yet well understood. While the link between increased temperatures and changes in rainfall has been modelled in detail, the same is not true for the effect on river flows and the recharge of underground waters. Specific challenges posed by the melting of snow and glaciers need to be better understood, as do impacts on water quality. Actions to implement robust water management are adaption actions. Understanding the dynamics of current variability and future climate change as they affect water supply and demand across all water-using sectors, and enhanced capacity to respond to these dynamics enables better water resources management. This strengthens resilience to current climate challenges, while building capacity to adapt to future climate change. Achieving and sustaining water security, broadly defined as harnessing water’s productive potential and limiting its destructive potential, provides a focus for adaptation strategies and a framework for action. For countries that have not achieved water security, climate change will make it harder. For those who have enjoyed water security, it may prove hard to sustain. All are likely to need to channel additional resources to water resource management. A focus on water security is a sound early adaptation strategy; delivering immediate benefits to vulnerable and underserved populations, thus advancing the Millennium Development Goals, while strengthening systems and capacity for longer-term climate risk management. Many societies will want to continue to invest in water management to move beyond water security and take fuller advantage of the economic, social and environmental benefits that can be derived from wiser water use. A water secure world will need investment in the three I’s: better and more accessible Information, stronger and more adaptable Institutions, and natural and man-made Infrastructure to store, transport and treat water. These needs will manifest at all levels – in projects, communities, nations, river basins and globally. Balancing and sequencing a mix of ‘soft’ (institutional and capacity) and ‘hard’ (infrastructure) investment responses will be complex. Information, consultation and adaptive management will be essential. Furthermore, tough trade-offs are likely to be unavoidable in balancing equity, environmental and economic priorities. Finding the right mix of the three I’s (information, institutions and infrastructure) to achieve the desired balance between the three E’s (equity, environment and economics), will be the ‘art of adaptation’ in water management. Integrated water resource management (IWRM) offers an approach to manage these dynamics and a thread that runs through these levels of engagement. IWRM is the global good practice approach to water management: it recognizes the holistic nature of the water cycle and the importance of managing trade-offs within it; it emphasizes the importance of effective institutions; and it is inherently adaptive. Financial resources will be needed to build this water secure world. Sound water management, which is a key to adaptation, is weakest in the poorest countries, which also suffer the greatest climate variability today and are predicted to face the greatest negative impacts of climate change. Significant investment will be needed in many of the poorest countries. Investment in national water resources management capacity, institutions and infrastructure should therefore be a priority for mainstreaming adaptation finance. It is sustainable development financing that delivers adaptation benefits. Mainstreamed funding will help ensure that long term capacity is built and retained in the institutions that are going to have to cope with these unfolding changes, and it will lessen the proliferation of complex climate change financing vehicles and fragmented, project-focused initiatives. In some transboundary basins the best adaption investments for any individual country may lie outside its borders, for example in basin-wide monitoring systems or investments in joint infrastructure and/or operating systems in a neighbouring country. To the extent that specialized adaptation funds are made available, they should go beyond single-country solutions to generate public goods and to promote cooperative transboundary river basin solutions where it is cost effective and in the best interest of all riparians.

Groundwater has played an important role in economic development in Southeast Asian countries, but some problems caused by nature or human actions such as contamination, over pumping, and land subsidence bring the necessity of more systematic groundwater monitoring wells. The analytical hierarchy process with pairwise comparison was used to allocate and organize the regional groundwater monitoring wells in five regions, Thailand, Cambodia, East/West Malaysia, and South Korea. Five different multi criteria decision models, which were composed of three primary criteria and eight secondary criteria, were developed based on the answers of the questionnaire from 76 groundwater experts in Thailand, 100 in Cambodia, 101 in East Malaysia, 87 in West Malaysia, and 93 in South Korea. It was revealed that the weights of model criteria for each country, which also represent relative importance on groundwater monitoring, were different according to the diverse groundwater situation. The most important factor to determine the number of monitoring well was ‘number of households using only groundwater as a water source’ for Thailand and South Korea, ‘number of contamination sources’ for Cambodia, ‘amount of groundwater use for drinking-water supply’ for East Malaysia, and ‘number of wells with contaminated water’ for West Malaysia.

Agricultural uses are responsible for approximately 48% of the total annual water use in South Korea. While approximately 70% of the annual rainfall is received during the summer season, most of the agricultural water is utilized from May to June. Therefore, irrigation facilities including reservoirs, canals and pumps were installed to efficiently manage agricultural water. Efficient operation of irrigation systems is important for sustainable irrigated agriculture, which is undermined due to the low water efficiency of the irrigation systems. Irrigation water management using web-based decision support systems is necessary to resolve water efficiency problems. In this study, automatic water gauges were installed at the main and secondary irrigation canals in the Dongjin River Basin, South Korea. The water levels in each canal were monitored and the irrigation water supply calculated. An irrigation model considering intermittent irrigation was developed to compare the estimated irrigation demands with the actual supplies for decision-making and demand strategies. Using this model and water-level data, a risk-based decision support system for the operation and management of agricultural water was developed and evaluated. Using this system. it is possible to optimally manage irrigation water and to make plans for efficient agricultural water operation and management.
