Responding to climate and other change processes in complex contexts:: Challenges facing development of adaptive policy frameworks in the Ganga Basin

The Ganga Basin, one of the world's most densely populated and vulnerable regions, is also among the world's most dynamic hydrological systems. Rivers exiting the Himalaya deposit massive amounts of sediment in the plains and shift their courses regularly. The natural dynamics of this system have a direct impact on populations. On August 18th, 2008, for example, embankments on the Kosi River (a tributary to the Ganges), failed and the channel shifted by as much as 120 km (Sinha, 2008 [1]) displacing over sixty thousand people in Nepal and three and a half million in India. Transport and power systems disrupted across large areas. The embankment failure was not caused by an extreme event. Instead the breach represented a failure of interlinked physical and institutional infrastructure systems in an area characterized by complex social, political, and environmental relationships.Projected climate changes in the Ganga Basin are likely to greatly exacerbate vulnerability (Adaptation Study Team, 2008 [2]). While the Kosi breach had nothing to do with climate change, such events will increase if climatic variability, sediment transport, and extreme events increase. Understanding how populations can respond to the dynamic nature of rivers such as the Kosi is, as a result, essential to develop strategies for adapting to climatic change. Understanding is also essential at the policy level for building adaptive capacity. The challenge is to identify policy frameworks and their relationship to interlinked physical and institutional infrastructure combinations that create environments enabling adaptation within households, communities, and regions.This paper explores the challenges and opportunities facing the development of adaptive policy frameworks in the Ganga Basin. The characteristics of frameworks that are adaptive in themselves and enable adaptation along with their relationship to different types of interlinked institutional and infrastructure systems are explored first. Following this, the case of the Kosi embankment along with the projected impacts of climate change across the Ganga Basin is used to identify the key challenges and opportunities that are common in many regions. The paper concludes with specific observations on the development of adaptive policy frameworks for responding to climate change in complex developing country contexts.     

Vulnerability assessment of water resources to climate change in Chinese cities

Climate change is an inevitable trend,which challenges security of water resources in China,especially in cities.Assessing vulnerability of water resource to climate change in cities has important role for policy makers. The paper constructs a vulnerability function,including exposure,sensitivity and adaptive capacity,according to the vulnerability concept proposed by IPCC,establishes an assessment indicators system of water resources to climate change in cities,and analyzes vulnerability features of Chinese cites based on 655 cities＇data in 2006.The vulnerability assessment results show that there are distinctive differences among all the cities,between east,central and west cities,between ordinary,big and mega cities,while there is no statistical significant difference between north and south cities.Based on the research,the paper suggests that strategic emphasis should focus on the central cities and ordinary cities     

Opening a policy window for organisational change and full-cost accounting: The creation of BC Hydro's water use planning program

British Columbia's Water Use Planning (WUP) program is a multi-stakeholder process that revises the operating plans of BC Hydro's hydroelectric facilities in order to consider water values beyond hydropower. Using a model of policy change, this paper analyses the circumstances that enabled the emergence of WUP and prompted BC Hydro to change its decision-making processes to better consider environmental and social concerns.External factors, including dam operations' ecological impacts, an imprecise regulatory environment, and worsening relationships with regulators, highlighted the need for a change in operating BC Hydro facilities. Factors internal to BC Hydro included the development of a business case, concerns regarding the utility's reputation and public expectations. While different approaches were explored for solving BC Hydro's problems, a policy window for change opened within a shifting context provided by the election of a more progressive government, the growth of the environmental movement, and new approaches to taking complex multi-stakeholder, multiple resource decisions. Following a successful pilot process and government direction to expand WUP, factors that enabled its institutionalisation included financial resources to compensate for the foregone power, the presence of visionary individuals, the background preparation that facilitated a successful pilot WUP, and the urgent need of a solution.
