<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>

Role Of Women

The natural resources are repository for the survival of all of us, so they must be used efficiently to meet the present needs while conserving them for future generations. An action to develop capacities from global to household levels for their sustainable management and regulation is required henceforth. Of these natural resources, water resources are most precious. If there is no water; there would be no life on earth. Since ‘water is the elixir of life’, water resource management has been considered as one of the most relevant areas of intervention. Understanding the gender dimensions of water resource management is a starting point for reversing the degradation of water resources. Women play an important role here since they have to access the water resources for almost all the activities on a daily basis. As the women are the strong social agents, effective and improved water preservation techniques could be achieved through their empowerment that may eventually lead to the well-being of the households in particular and of the community in general. Therefore, the major research question posed in this study is to analyze the role of women in the preservation and management of water, an inevitable, precious but diminishing natural resource. The study also intends to describe the relationship between the three ‘W's-Women, Water & Well-being. Both qualitative and quantitative approaches are essential here as it is a contingent issue in the present scenario. Psychological dimensions were also explored since the issue is affecting the routine life of the community. The case study of women belonging to the Kuttadampadam region was done to explain the role of women in preserving water resources in the areas affecting severe water scarcity.

Abstract Fast-growing water demand, population growth, global climate change, and water quality deterioration all drive scientists to apply novel approaches to water resource management. Nanotechnology is one of the state-of-the-art tools in scientists’ hands which they can use to meet human water needs via reuse of water and utilizing unconventional water resources. Additionally, monitoring water supply systems using new nanomaterials provides more efficient water distribution networks. In this chapter, we consider the generic concepts of nanotechnology and its effects on water resources management strategies. A wide range of nanomaterials and nanotechnologies, including nano-adsorbents, nano-photocatalysts, and nano-membranes, are introduced to explain the role of nanotechnology in providing new water resources to meet growing demand. Also, nanomaterial application as a water alternative in industry, reducing water demand in the industrial sector, is presented. Another revolution made by nanomaterials, also discussed in this chapter, is their use in water supply systems for monitoring probable leakage and leakage reduction. Finally, we present case studies that clarify the influence of nanotechnology on water resources and their management strategies. These case studies prove the importance and inevitable application of nanotechnology to satisfy the rising water demand in the modern world, and show the necessity of nanotechnology awareness for today's water experts.

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.

Abstract The demand for water resources is consistently increasing due to industrialization and urbanization. Water resource management can become difficult because of climate change and social issues. Due to the difficulty in securing stable water resources, reasonable utilization and management of water is crucial for the sustainable development of groundwater resources that are an efficient alternative to surface water. For groundwater management, the National Groundwater Information Management Service (GIMS) Center for K-Water measures groundwater data hourly (groundwater level, water temperature, and electrical conductivity) at national groundwater monitoring stations and analyzes the long-term variation of groundwater with regard to climate change. According to the Groundwater Act (1993), auxiliary groundwater monitoring stations for groundwater use and water quality are activated by local governments. The observed data after the calibration process are provided for utilization by citizens, industries, schools, institutes, and government policies through annual reports on groundwater monitoring by the GIMS Center. In 2018, the Korean government merged water resources affairs that were once divided between the Ministry of Environment and the Ministry of Land, Infrastructure, and Transport. The change will be favorable for effective management of the surface water and groundwater resources as well as ensuring both quality and quantity.
