Impacts Of Climate Change

Asia, a region grappling with the impacts of climate change, increasing natural disasters, and transboundary water issues, faces major challenges to water security. Water resources there are closely tied to the dramatic Hindu-Kush Himalayan (HKH) mountain range, where over 46,000 glaciers hold some of the largest repositories of fresh water on earth (Qiu 2010). Often described as the water tower of Asia, the HKH harbors the snow and ice that form the headwaters of the continent's major rivers (Bandyopadhyay 2013). Downstream, this network of river systems sustains more than 1.3 billion people who depend on these freshwater sources for their consumption and agricultural production, and increasingly as a source of hydropower (Immerzeel, Van Beek, and Bierkens 2010; National Research Council 2012; Rasul 2014).

Impacts Of Climate Change

Climate change will bring about unprecedented economic, social and environmental effects, which require both the mitigation of greenhouse gas emissions and adaptation to its adverse effects. Water is the main element through which the impacts of climate change will be felt. Climate change results in increased uncertainties, complexities, stress and potential for conflicts within water management, both among and within states. New forms of governance are needed if the world is to respond to the need to adapt to changes in freshwater supply and to manage water security risks.This paper suggests that adaptive governance should to be main-streamed into all water regulation to ensure the availability of and access to safe water resources and to prevent water-related conflicts. The paper discusses the concept of water security in the context of climate change, the threats that climate change poses to water security, and the concept and implications of adaptive governance as a possible solution.The application of adaptive governance requires a certain degree of institutional and normative flexibility, instruments and institutions that can respond and adapt to changes and manage the level of uncertainty associated with the impacts of climate change. The governance institutions, methods and instruments should be responsive to new information and different kinds of uncertainties, while reflecting the vulnerabilities, capacities, needs and priorities of both societies and ecosystems in the face of climate change. Water security risks could be reduced by increased hydrosolidarity among states, which would present the challenges posed by climate change on water governance and security as primarily an opportunity for new forms of cooperation.

Impacts Of Climate Change

Some of the most significant impacts of climate change are likely to be felt in water resources management, but climate change is not the only uncertainty facing water managers and policymakers. The concept of water security has emerged to address social, economic, political, and environmental factors, as well as the physical determinants of water availability. There are significant challenges for communicating about water security under a changing climate. Water security shares many of the characteristics of climate change with regards to communication. It is a complex concept involving interactions between dynamic human and natural systems, requiring public deliberation and engagement to inform political debate and to facilitate behavioral and cultural change. Knowledge and values about water and climate change are communicated through material experiences as well as through language. Communication about water security and climate change takes many forms, which can be characterized as five key modes—policy, communication campaigns, media, cultures, and environments. More effective communication about climate change and water is needed across these different modes to support meaningful participation and deliberation in policy decisions by a wide range of stakeholders. Integrating climate change into communication campaigns about water security provides opportunities to challenge and reframe traditional formulations of the role of water in society and culture and how to manage water in human settlements, the economy, and the environment. The central challenge for communicating the impacts of climate change on water scarcity lies in the complex interactions between society, policy, technology, infrastructure, the economy, and the environment in modern water systems. Different modes of communication are useful to enable public and stakeholder engagement in understanding the issues and making decisions about how to ensure water security in a changing society and environment.

Purpose This paper aims to describe how social capital is mobilized in the mediation of periurban water insecurity induced by urbanization and climate change. Investing in social capital through the process of creating mechanisms for civic engagement is an important means of building resilience of periurban communities. Design/methodology/approach This paper draws on ethnographic and action research. The main sources of data were direct observation of water appropriation and access and semi-structured interviews. Convenience, snowball and theoretical sampling were used. Findings The residents of periurban Gurgaon have lost access to water on account of urbanization and climate change. In this context, they mobilize social relationships to collectively improve their access to water. Norms of cooperation and kinship play an important role in the mediation of water insecurity. Creating social capital by building platforms for civic engagement helped to improve their water security. Originality/value While there has been much interest in issues of periurban water insecurity, the role of social capital in the mediation of water insecurity has received scant attention. At the same time, while scholars have been interested in the role of social capital in adapting to the impacts of climate change, it has scarcely been studied in a periurban context. This paper seeks to bridge this research gap.
