Using China as a case study, a methodology is presented to estimate the changes in yields and costs of present and future water production systems under climate change scenarios. Yield is important to consider because it measures the actual supply available from a river basin.

resultsIn the Andes, runoff from glacierized basins is an important element of water budgets, assuring year-round flows for agriculture, potable water, power generation, and ecosystem integrity. Thus, changes induced by tropical glacier retreat constitute an early case of the need for adaptation and the type and size of associated economic and social impacts caused by climate change.
Climate change due to global warming will reduce river flows across much of Australia and reduce the yield of existing urban and rural water systems. These reductions are additional to yield reductions that have flowed from the allocation of more water for environmental flows under national water reforms, and the severity of the 2001-2007 drought in southern Australia.
In this document, the methodology and the concepts for prioritisation of adaptation measures are comprehensively explained. Prior to this, a theoretical focus is presented to link the concepts of climate change, water, adaptation and economics.
This report describes the CEA methodology and how we have implemented this in CLIMSAVE. We address key methodological issues referring to uncertainty and report in detail on specific topics. We conclude with insights gained and proposals for the further development of the CEA methodology.
This technical background paper reviews and analyses existing and projected investment flows and financing relevant to the development of an effective and appropriate international response to climate change, with particular focus on the needs of developing countries.
Speech on the policy issues in the climate debate that affect water resource management with examples from Southern and subSaharan Africa more generally, because it is one of the regions where the challenges and threats are greatest and the resources and ability to respond most limited.
Sea level rise (SLR) due to climate change will increase storm surge height along the 825 km long coastline of Metro Boston, USA. Land at risk consists of urban waterfront with piers and armoring, residential areas with and without seawalls and revetments, and undeveloped land with either rock coasts or gently sloping beachfront and low-lying coastal marshes.
Post-project appraisals were carried out for flood protection projects completed during 1960–1987 in six locations in England and Wales. The methodology focused on assessing the implications of new hydrological-hydraulic analyses of flood risks, and of urban land use changes.
Flooding due to extreme rain events in urban environments is a problem and a growing concern. When the stormwater systems design return period are greatly exceeded during extreme rain events, flooding is inevitable. However, the flood consequences can be mitigated by surface water management.
This paper demonstrates the application of cost effectiveness analysis and cost benefit analysis to alternative avalanche risk reduction strategies in Davos, Switzerland. The advantages as well as limitations of such analysis for natural hazards planning are discussed with respect to 16 avalanche risk reduction strategies.
The Ourcoast-Database includes case studies that reflect successful examples of Integrated Coastal Zone Management (ICZM) approach and tools applied throughout the European Member States.
With this climate adaptation plan we will outline the challenges the city faces in the short and medium terms as a result of changes we expect in the future climate. We will also identify those solutions that, based on our present-day knowledge, appear to be most appropriate and reveal the opportunities climate change may also present to the city.
Lee catchment flood risk assessment and management study. Draft catchment flood risk management plan
Catchment Flood Risk Assessment and Management Studies (CFRAMSs) and their product - Catchment Flood Risk Management Plans (CFRMPs) - are at the core of this new national policy for flood risk management and the strategy for its implementation. This policy is in line with international best practice and meets the requirements of the EU Floods Directive.
The guide serves as a primer for decision and policy makers, technical specialists, central, regional and local government officials, and concerned stakeholders in the community sector, civil society and non-governmental organizations, and the private sector. The Guide embodies the state-of-the art on integrated urban flood risk management.
Although sea-level rise (SLR) is not the only driver of coastal change, it is expected to radically alter the living conditions and prosperity of coastal communities in the decades to come.
Adaptive flood risk management under climate change uncertainty using Real Options and optimization.
It is well recognized that adaptive and flexible flood risk strategies are required to account for future uncertainties. Development of such strategies is, however, a challenge. Climate change alone is a significant complication, but, in addition, complexities exist trying to identify the most appropriate set of mitigation measures, or interventions.
Cost-benefit analyses (CBA) of flood management plans usually require estimating expected annual flood damages on a study area, and rely on a complex modelling chain including hydrological, hydraulic and economic modelling as well as GIS-based spatial analysis. As most model-based assessments, these CBA are fraught with uncertainty.
To show the progress in Europe on adaptation to climate change and to showcase inspirational and daring adaptation projects ERANET CIRCLE-2 works on a bold and visual inspiration book with good practices of implementation of adaptation strategies and projects in Europe. While most people may have a rough comprehension of climate change, the phrase adaptation often invites only raised eyebrows.
Infrastructure for water, urban drainage and flood protection has a typical lifetime of 30–200 years and its continuing performance is very sensitive to climate change. Investment decisions for such systems are frequently based on state-of-the-art impact assessments using a specified climate change scenario in order to identify a singular optimal adaptive strategy.
This report contributes to the theoretical framework of the Committee on Climate Change Adaptation Sub-Committee’s work on assessing the preparedness of the UK to meet the risks and opportunities arising from climate change.
Recent destructive flood events and projected increases in flood risks as a result of climate change in many regions around the world demonstrate the importance of improving flood risk management. Flood-proofing of buildings is often advocated as an effective strategy for limiting damage caused by floods.
This paper presents a cross-disciplinary framework for assessment of climate change adaptation to increased precipitation extremes considering pluvial flood risk as well as additional environmental services provided by some of the adaptation options.
Rising sea levels are expected to cause an increased risk of coastal flooding in many regions and adaptation to these threats is necessary to avoid considerable losses. Yet, such measures will typically only be implemented if they are economically efficient, that is, if the benefits in terms of avoided damages exceed the implementation costs.
