Towards the harmonization of water-related policies for managing drought risks across the EU

Drought is recognized as a major issue in the EU, particularly in the Mediterranean region, posing risks to the environment as well as to local and regional economies. The EU policy on water management is continuously evolving, particularly in relation to water scarcity and drought. Starting with the Water Framework Directive (2000/60/EC), which sets the general policy framework for water management across the EU, the EC Communication on Water Scarcity and Drought COM(2007) 414 final set the priorities for managing water scarcity and drought risks. Three follow-up reports (COM(2008) 875 final, COM(2010) 228 final and COM(2011) 133) highlighted achievements and yearly progress within the context of the implementation of the Water Framework Directive, whereas guidance has further been provided through the issue of Technical Reports (e.g. the EC Water Scarcity Drafting Group Technical Report 2008–023 on Drought Management, Including agricultural, drought indicators and climate change aspects). The 2012 EU Water Review (“Blue Print for Safeguarding European Waters” will assess achievements and identify further requirements towards long-term sustainable water use across the EU. However, a harmonized approach on drought risk management at the EU level is still lacking, whereas drought risk in several countries and regions has not been yet fully integrated in water management and relevant sectoral policies.This paper focuses on a proposed paradigm shift from crisis to risk management, which is currently gaining ground as a means of reducing societal vulnerability to droughts. The paper underlines the importance of engaging into risk assessment and management practices and identifies policy gaps and requirements for further improvement of the drought management policy framework at all levels of governance: at the EU, at the national and at the river basin and regional levels.     

The science and politics of co-benefits in climate policy

The co-benefits concept implies a ‘win–win’ strategy to address two or more goals with a single policy measure. There is much scholarly and policy attention paid to this concept as a way to avoid making trade-offs between developmental and environmental issues. However, there is no review paper that reviews the nature, evolution, strengths and limits of the co-benefits concept in relation to climate change. Hence, this review article addresses the question: What does the literature tell us about the definition, application and use of the co-benefits concept? Using a literature review approach, this article explains the evolution of the co-benefits concept and its strengths and weaknesses. We conclude that while the concept has tremendous advocacy potential in dealing with the problem that the costs and benefits of climate policy are temporally and spatially not aligned, its de facto potential is limited as mostly economists have engaged with this concept, and there is little trans-disciplinary work undertaken that also looks at the politics and institutional aspects of co-benefits. The article thus provides an impetus to rethink current approaches to studying co-benefits and points to the need for inter- and trans-disciplinary research drawing on economic, political and social sciences.     

Moving towards ambitious climate policies: Monetised health benefits from improved air quality could offset mitigation costs in Europe

Air quality and related health effects are not only affected by policies directly addressed at air pollution but also by other environmental strategies such as climate mitigation. This study addresses how different climate policy pathways indirectly bear upon air pollution in terms of improved human health in Europe. To this end, we put in perspective mitigation costs and monetised health benefits of reducing PM_2.5 (particles less than 2.5 μm in diameter) and ozone concentrations.Air quality in Europe and related health impacts were assessed using a comprehensive modelling chain, based on global and regional climate and chemistry-transport models together with a health impact assessment tool. This allows capturing both the impact of climate policy on emissions of air pollutants and the geophysical impact of climate change on air quality.Results are presented for projections at the 2050 horizon, for a set of consistent air pollution and climate policy scenarios, combined with population data from the UN's World Population Prospects, and are expressed in terms of morbidity and mortality impacts of PM_2.5 and ozone pollution and their monetised damage equivalent.The analysis shows that enforcement of current European air quality policies would effectively reduce health impacts from PM_2.5 in Europe even in the absence of climate policies (life years lost from the exposure to PM_2.5 decrease by 78% between 2005 and 2050 in the reference scenario), while impacts for ozone depend on the ambition level of international climate policies. A move towards stringent climate policies on a global scale, in addition to limiting global warming, creates co-benefits in terms of reduced health impacts (68% decrease in life years lost from the exposure to PM_2.5 and 85% decrease in premature deaths from ozone in 2050 in the mitigation scenario relative to the reference scenario) and air pollution cost savings (77%) in Europe. These co-benefits are found to offset at least 85% of the additional cost of climate policy in this region.     

Reforming the CDM for sustainable development: lessons learned and policy futures

The Clean Development Mechanism (CDM) has successfully demonstrated that market-based mechanisms can achieve some cost effective emissions reductions in developing countries. However the distribution of CDM projects has been extremely uneven across countries and regions, and a few technologies and sectors have dominated the early stages of CDM experience. This has caused some to question whether the CDM has fallen short of its potential in contributing to sustainable development. We review the broad patterns of CDM project approvals and evaluate 10 CDM projects according to their sustainability benefits. The difficulty of defining “sustainable development” and the process of defining criteria by individual non-Annex 1 governments has meant that sustainable development concerns have been marginalized in some countries. Given these observed limitations, we present possible CDM policy futures, focusing on the main proposals for a post-2012 climate regime. Five options for enhancing the sustainable development benefits in the CDM are discussed, including proactive approaches to favour eligibility of emission reduction projects which ensure such co-benefits.     

Institutional challenges to climate change adaptation: A case study on policy action gaps in Uganda

Despite the considerable progress made in the last decade towards building governance systems for climate change adaptation in Africa, implementation still limits positive responses. This study applies an iterative process of field assessments and literature reviews across multiple governance levels and spatial scales to identify constraints to effective formulation and implementation of climate change related policies and strategies in Uganda. Data was collected through sex-segregated participatory vulnerability assessments with farming communities in Rakai district, policy document reviews, and interviews with policy actors at national and district levels. Findings reveal that the key challenges to effective policy implementation are diverse and cut across the policy development and implementation cycle. Policies are mainly developed by central government agencies; other actors are insufficiently involved while local communities are excluded. There is also a communication disconnect between national, district, and community levels. Coupled with limited technical capacity and finances, political interference, and absence of functional implementation structures across these levels, climate change adaptation becomes constrained. We propose strategies that enhance linkages between levels and actors, which will improve policy formulation, implementation and ultimately adaptation by smallholders.     

A Framework for Benefit-Cost Analysis of Adaptation to Climate Change and Climate Variability

The potential damages of climate change and climate variability are dependent upon the responses or adaptations that people make to their changing environment. By adapting the management of resources, the mix and methods of producing goods and services, choices of leisure activities, and other behavior, people can lessen the damages that would otherwise result. A framework for assessing the benefits and costs of adaptation to both climate change and climate variability is described in the paper. The framework is also suitable for evaluating the economic welfare effects of climate change, allowing for autonomous adaptation by private agents. The paper also briefly addresses complications introduced by uncertainty regarding the benefits of adaptation and irreversibility of investments in adaptation. When investment costs are irreversible and there is uncertainty about benefits, the usual net present value criterion for evaluating the investment gives the wrong decision. If delaying an adaptation project is possible, and if delay will permit learning about future benefits of adaptation, it may be preferable to delay the project even if the expected net present value is positive. Implications of this result for adaptation policy are discussed in the paper.     

How robust is public support for unilateral climate policy?

Most governments emphasize the need for reciprocal (“give and take”) international commitments in global climate policy. Nonetheless, existing public opinion polls indicate strong support by individual citizens for unilateral climate policies as well. This raises the question of whether governments could, without risking electoral punishment, afford to pursue more ambitious unilateral climate policies, or whether surveys may have overestimated support for unilateralism due to measurement problems. Based on conjoint and framing experiments embedded in representative surveys in the world's two largest democracies, India and the United States, we engage in a critical re-assessment of earlier survey results. We find robust public support for unilateral climate policy in both countries. Such support declines with increasing costs and increases with growing co-benefits and problem solving effectiveness. We also find, however, that policy conditionality and possible institutional design mechanisms against free-riding by other states (which make the policy “less unilateral” by providing for reciprocation) play no significant role when citizens form their preferences with respect to climate policy. Neither is public support affected by whether policies focus on adaptation (which limits benefits to the investing country) or mitigation (which benefits all countries globally). Overall, these findings suggest that, in view of very slow progress in global climate policy, governments of rich and poor countries could politically afford to push ahead with more ambitious unilateral climate policies.     

Motivations and barriers for Western Australian broad-acre farmers to adopt carbon farming

Carbon farming policies aim to contribute to climate change mitigation, but their success strongly depends on whether landholders actually adopt desired practices or participate in offered programs. The Australian Government’s Carbon Farming Initiative and Emissions Reduction Fund policies were designed to incentivise the adoption of carbon farming practices. Although these policies have been active since December 2011, farmer engagement has been limited, and net emissions reductions low as a result. We surveyed broad-acre farmers in the Western Australian wheatbelt to explore their drivers and barriers to adopting carbon farming practices and participating in carbon farming policy programs. Drivers of adoption included knowledge and perception of co-benefits (for yield, productivity, and the environment), knowing another adopter, and believing that changes to farm management are an appropriate method to reduce Australia’s greenhouse gas emissions. Barriers to adoption included lack of information, uncertainty and costs. The key barrier to participation was policy and political uncertainty. The determinants of adoption and participation that we identify in our study offer important insights into how to best ensure the success of Australia’s land sector-based climate change policies. We conclude that, to increase landholder engagement, the co-benefits and climate change benefits of carbon farming practices must be actively promoted, and additional information is needed about the costs associated with adoption. Information diffusion is best achieved if it actively leverages landholder social networks. Finally, our results indicate that landholder buy-in to carbon farming could be greatly enhanced by achieving more continuity in Australian climate change policies and politics.     

Methodology to translate policy assessment problems into scenarios: the example of the SEAMLESS integrated framework

Scenario-based approaches in environmental and policy assessment studies are increasingly applied within integrated assessment and modelling frameworks. The SEAMLESS project develops such an integrated framework (SEAMLESS-IF) aiming to assess, ex-ante, impacts of alternative agro-environmental policies on the sustainability of agricultural systems. A particular challenge in this context is the consistent translation of a wide range of policy questions into scenarios that a modelling framework can assess. The present work defines a methodology for scenario-development in integrated policy assessment with specific emphasis on SEAMLESS-IF. After a general overview on scenario concepts for integrated policy assessment the adopted scenario concept and its development procedure is presented. They allow building integrated scenarios capturing the range of drivers of the assessed agricultural system in a consistent way across temporal and spatial scales. Then focus is on the particular procedures to translate the policy assessment questions into scenario parameters and to implement these parameters into SEAMLESS-IF. Two examples targeted at European and regional level combining integrated assessments of policy changes and technological innovations are considered to illustrate the SEAMLESS scenario concept. We conclude that the proposed methodology to translate policy assessment problems into scenarios effectively supports integrated assessment in SEAMLESS-IF or even in other modelling frameworks.     

A multi-level perspective on learning about climate change adaptation through international cooperation

International cooperation and learning may accelerate climate change adaptation and help countries and regions to adapt more effectively and efficiently. Recognizing the importance and opportunities for mutual learning and knowledge transfer, international and supranational organizations, such as the European Commission, have put programmes for international cooperation in place. This paper presents and tests a framework for assessing multi-level learning outcomes of such international cooperation processes and the conditions that produce these outcomes. The framework distinguishes between: (1) group learning by individual process participants; (2) organizational learning by organizations represented in the process; and (3) network and societal learning by actors external to the process. We verify the analytical potential of the framework by comparing learning by six partners in an adaptation-oriented European cooperation project. The project scores rather high on group learning with participants learning from and – to a lesser extent – also with each other. Learning by partner organizations varied and was generally less whereas learning by external actors was very limited. The case study confirms our expectation that learning outcomes are produced by combinations of partner-specific, process-specific and process-external conditions. The presented framework and insights can be used to stimulate learning in and from international cooperation processes.     

The potential of behavioural change for climate change mitigation: a case study for the European Union

Mainstream literature on climate change concentrates overwhelmingly on technological solutions for this global long-term problem, while a change towards climate-friendly behaviour could play a role in emission reduction and has received little attention. This paper focuses on the potential climate mitigation by behavioural change in the European Union (EU) covering many behavioural options in food, mobility and housing demand which do not require any personal up-front investment. We use the Global Change Assessment Model (GCAM), capturing both their direct and indirect implications in terms of greenhouse gas emissions. Our results indicate that modest to rigorous behavioural change could reduce per capita footprint emissions by 6 to 16%, out of which one fourth will take place outside the EU, predominantly by reducing land use change. The domestic emission savings would contribute to reduce the costs of achieving the internationally agreed climate goal of the EU by 13.5 to 30%. Moreover, many of these options would also yield co-benefits such as monetary savings, positive health impacts or animal wellbeing. These results imply the need for policymakers to focus on climate education and awareness programs more seriously and strategically, making use of the multiple co-benefits related with adopting pro-environmental behaviour. Apart from that, the relevance of behavioural change in climate change mitigation implies that policy-informing models on climate change should include behavioural change as a complement or partial alternative to technological change.     

How to perform an environmental management cost assessment in one day

The article provides definitions for environmental accounting and environmental management accounting based on the approach developed for the United Nations Division of Sustainable Development UN DSD/DESA. It presents the basic framework for assessing corporate environmental costs as well as materials flows (including energy and water) and their costs. The paper is based on experiences from applying the UN DSD EMA framework in company workshops and case studies mainly in Austria. It especially describes how to check for data consistency within different information systems, like the list of accounts, stock management, production planning and process engineering. Common hurdles for obtaining data from different information systems are described and solutions for improved consistency of data in an organization are presented. It provides a detailed example of an assessment in a brewery in the excel tool developed to assist in the application of the UN DSD EMA approach.     

Learning about climate change solutions in the IPCC and beyond

There has been much debate about the assessment process of the Intergovernmental Panel on Climate Change (IPCC). Yet two of the most fundamental challenges that directly threaten the ability of the IPCC to fulfill its mandate have been largely neglected so far. Firstly, the magnitude and rapid expansion of the climate change literature makes it increasingly impossible for the IPCC to conduct comprehensive and transparent assessments without major innovations in assessment practices and tools. Secondly, the structure, organization and scientific practices across the social sciences and humanities prohibit systematic learning on climate change solutions and increasingly limit the policy-relevance of IPCC assessments. We highlight the need for responses along three avenues to prepare the IPCC for continued success in the future: 1) IPCC assessments must make better use of big-data methods and available computational power to assess the growing body of literature and ensure comprehensiveness; 2) systematic review practices need to be enshrined into IPCC procedures to ensure adequate focus and transparency in its assessments; 3) a synthetic research culture needs to be established in the social sciences and humanities in order to foster knowledge accumulation and learning on climate solutions in the future. As policymakers become more interested in understanding solutions, the future prospects of global environmental assessment enterprises will depend heavily on a successful transformation within the social sciences and humanities towards systematic knowledge generation. This article is part of a special issue on solution-oriented Global Environmental Assessments.     

Re-thinking water policy priorities in the Mediterranean region in view of climate change

Water is scarce in Mediterranean countries: cities are crowded with increasing demand; food is produced with large amounts of water; ecosystems demand more water that is often available; drought affects all. As climate change impacts become more noticeable and costlier, some current water management strategies will not be useful. According to the findings of CIRCE, the areas with limited water resources will increase in the coming decades with major consequences for the way we produce food and we protect ecosystems. Based on these projections this paper discusses water policy priorities for climate change adaptation in the Mediterranean. We first summarise the main challenges to water resources in Mediterranean countries and outline the risks and opportunities for water under climate change based on previous studies. Recognising the difficulty to go from precipitation to water policy, we then present a framework to evaluate water availability in response to natural and management conditions, with an example of application in the Ebro basin that exemplifies other Mediterranean areas. Then we evaluate adaptive capacity to understand the ability of Mediterranean countries to face, respond and recover from climate change impacts on water resources. Social and economic factors are key drivers of inequality in the adaptive capacity across the region. Based on the assessment of impacts and adaptive capacity we suggest thresholds for water policy to respond to climate change and link water scarcity indicators to relevant potential adaptation strategies. Our results suggest the need to further prioritise socially and economically sensitive policies.     

Tools for developing adaptation policy to protect human health

Anthropogenic climate change is likely to add significant pressure to the determinants of public health, and to current health and social protection measures in high, middle and low income countries. Adaptation strategies within the health sector are being developed to address the multi-dimensional nature of the costs and impacts. We further develop and apply a new generic conceptual framework for development-compatible climate policy planning to evaluate policy options for middle and low income countries that reduce the adverse health effects of climate change. The criteria used for comparative evaluation included economic, environment, social and institutional factors. The proposed framework, incorporating system dynamics, provides a foundation for a decision-analytical approach to support the formulation of robust climate change adaptation policies to protect human health.     

Co-benefits of post-2012 global climate mitigation policies

This paper provides an analysis of co-benefits for traditional air pollutants made possible through global climate policies using the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model in the time horizon up to 2050. The impact analysis is based on projections of energy consumption provided by the Prospective Outlook for the Long term Energy System (POLES) model for a scenario without any global greenhouse gas mitigation efforts, and for a 2°C climate policy scenario which assumes internationally coordinated action to mitigate climate change. Outcomes of the analysis are reported globally and for key world regions: the European Union (EU), China, India and the United States. The assessment takes into account current air pollution control legislation in each country. Expenditures on air pollution control under the global climate mitigation regime are reduced in 2050 by 250 billion € when compared to the case without climate measures. Around one third of financial co-benefits estimated world-wide in this study by 2050 occur in China, while an annual cost saving of 35 billion (Euros) € is estimated for the EU if the current air pollution legislation and climate policies are adopted in parallel. Health impacts of air pollution are quantified in terms of loss of life expectancy related to the exposure from anthropogenic emissions of fine particles, as well as in terms of premature mortality due to ground-level ozone. For example in China, current ambient concentrations of particulate matter are responsible for about 40 months-losses in the average life expectancy. In 2050, the climate strategies reduce this indicator by 50 %. Decrease of ozone concentrations estimated for the climate scenario might save nearly 20,000 cases of premature death per year. Similarly significant are reductions of impacts on ecosystems due to acidification and eutrophication.     

Understanding interactive knowledge development in coastal projects

Various concepts have been developed that refer to interactive modes of knowledge production. Examples such as Mode 2 knowledge and post-normal science highlight the involvement of researchers, decision makers and other societal actors, in order to develop relevant knowledge for decision making. Existing research into such modes of knowledge development focuses on the interfaces between science, policy, and society. This paper introduces a conceptual framework for the connection between interactive knowledge development and a project environment. The aim of this paper is to improve the understanding of interactive knowledge development in a project environment, by presenting a case study of interactive knowledge development in a coastal project. Coastal projects intend to develop solutions in the coastal zone: a dynamic and fast changing environment. This paper adapts the policy arrangement approach to study interactive knowledge development longitudinally in the Texel dike reinforcement project. Eight mechanisms are derived that affect and explain the process of interactive knowledge development in this case. The mechanisms indicate how interactive knowledge development may result in more relevant knowledge and broadly accepted solutions.     

Bio-energy supply chains and stakeholders

What are the management challenges and opportunities of bio-energy chains for both running their business efficiently and effectively and fostering the relationships with most relevant external stakeholders? This question is approached by systematically reviewing papers at the interface of bio-energy and supply chain or logistics issues. The review conducted as content analysis is based on an analytic framework that conceives bio-energy chains between challenges and benefits of bio-energy production with simultaneous internal supply chain management and external stakeholder management needs. Smartly designed and operated bio-energy projects hold promising potentials of contributing to sustainable development by both mitigating climate change and strengthening adaptation capabilities. Our analysis distils specific strategies and success factors for tapping this potential on two levels: On a supply chain level, individually adapted and designed supply chain systems relying on trustful information exchange, cooperation and relational governance safeguard profitability while holding adverse ecological and social impacts of operation down; they allow, for instance, minimising costs and emissions, implementing new technologies, and coping with environmental uncertainties such as crop failures and volatile prices. On a stakeholder level, governments as key actors for designing the future legal framework of bio-energy are primary targets for lobbying activities of bio-energy representatives. Respective arguments may focus on economic development and job generation. By minimising its adverse impacts on society and eco-systems and by communicating these efforts credibly, bio-energy warrants its superiority over fossil energy systems. Involving NGOs and residents in early stages of bio-energy projects via transparent two-way communication considerably increase societal acceptance.     

Opportunities for adaptation-mitigation synergies in geothermal energy utilization- Initial conceptual frameworks

In this article, the role of geothermal energy in mitigation and potential role in adaptation are discussed, and synergies between them developed. The article creates the Geothermal Adaptation-Mitigation (Geo-AdaM) conceptual frameworks that can be used in combining mitigation and adaptation in geothermal projects, e.g. by introducing adaptation additionality in Clean Development Mechanism or mitigation projects, using geothermal energy in climate vulnerable sectors, combining geothermal development with carbon forestry to improve recharge of geothermal systems in water stress areas, displacing fossil fuels in heating and cooling, and use of geothermal heat in raising tree seedlings in cold regions, and in greenhouses to create carbon sinks and green areas. The conceptual frameworks created in this research can cut across most regions, and types of utilization schemes with mitigation/adaptation co-benefits. The resulting co-benefits come with net positive environmental, economic and social impact. However, the co-benefits cannot be homogenous across all projects and regions. Tradeoffs may occur when using geothermal energy in adaptation projects, whose upstream activities are carbon intensive, or in adaptation and mitigation projects that have the potential of increasing vulnerability. The foreseen limitations of creating the synergies include; inadequate research on geothermal energy and adaptation, nature and scale of adaptation, involvement of different institutions and actors, access to finance and other resources especially in developing countries and lack of clear legal framework. Without proper legislation, fiscal incentives, to attract investment in adaptation aspects of geothermal energy, and to guard against tradeoffs, the interelationships between the two will remain a pipe dream.     

Cap and trade policy for managing water competition from potential future carbon plantations

Carbon sequestration from reforestation can play a large role in mitigating global climate change. However, resulting interception of rainfall runoff may impose high irrigation, water supply and/or environmental flow costs. This article presents an assessment of water trade policy to manage fresh water supply, carbon sequestration trade-offs for the Murray-Darling Basin. A linked Australian high spatial resolution land use and global integrated assessment framework evaluated plausible and internally-consistent global scenarios to 2050 involving significant carbon planting incentive. Substantial flow loss from increased interception was estimated absent policy to balance carbon water trade-offs. Absent policy to address the trade-off, irrigation opportunity costs was estimated to substantially exceed carbon sequestration economic value in futures with significant carbon sequestration incentive. The value of integrating interception from new carbon plantings into the existing water trade system was estimated at $3.3 billion and $2.0 billion (2050 annual value) for our strong and moderately strong global climate action outlooks with our reference case assumptions. The conclusion that trade provision in policy to cap interception impacts can produce significant benefits in scenarios with significant carbon sequestration incentive remained robust over a very broad set of sensitivities tested with benefit estimated at over $1 billion annually at 2050 even for very conservative assumptions.
