Climate change and coastal vulnerability assessment: scenarios for integrated assessment

Coastal vulnerability assessments still focus mainly on sea-level rise, with less attention paid to other dimensions of climate change. The influence of non-climatic environmental change or socio-economic change is even less considered, and is often completely ignored. Given that the profound coastal changes of the twentieth century are likely to continue through the twenty-first century, this is a major omission, which may overstate the importance of climate change, and may also miss significant interactions of climate change with other non-climate drivers. To better support climate and coastal management policy development, more integrated assessments of climatic change in coastal areas are required, including the significant non-climatic changes. This paper explores the development of relevant climate and non-climate drivers, with an emphasis on the non-climate drivers. While these issues are applicable within any scenario framework, our ideas are illustrated using the widely used SRES scenarios, with both impacts and adaptation being considered. Importantly, scenario development is a process, and the assumptions that are made about future conditions concerning the coast need to be explicit, transparent and open to scientific debate concerning their realism and likelihood. These issues are generic across other sectors.

Motivation of Japanese companies to take environmental action to reduce their greenhouse gas emissions: an econometric analysis

To analyze the motivations of Japanese companies to take environmental actions to reduce their greenhouse gas (GHG) emissions, we used FY2006 research data and questioned Japanese industries regarding their reduction of GHG emissions. Empirical investigations revealed that voluntary targets set by industry organizations, government requirements, and advance responses to possible future regulations can positively influence environmental actions for GHG emission reduction; however, cost reductions and corporate social responsibility fulfillment cannot.

The impact of climate change on tourism in Germany,the UK and Ireland: a simulation study

We downscale the results of a global tourism simulation model at a national resolution to a regional resolution. We use this to investigate the impact of climate change on the regions of Germany, Ireland and the UK. Because of climate change, tourists from all three countries would spend more holidays in the home country. In all three countries, climate change would first reduce the number of international arrivals—as Western European international tourist demand falls—but later increase numbers—as tourism demand from increasingly rich tropical countries grows. In Ireland and the UK, the regional pattern of demand shifts is similar to the international one: tourism shifts north. In Germany, the opposite pattern is observed as the continental interior warms faster than the coast: tourism shifts south.

Social determinants of soil and water conservation in rural Kenya

Soil erosion is a major environmental problem and threat to rural development in Kenya. Numerous attempts to address the problem have apparently had little success. There are however some districts that have been very successful, notably Machakos. In this study we search for the factors that determine successful development in soil conservation such as social capital, human capital and market integration. One of our main results is that social capital measures are significant determinants of investment in soil conservation. A better understanding of the relevant mechanisms is essential for developing policies targeting improvement in natural resource management.

Using a functional approach to wetland valuation: the case of Zazari–Cheimaditida

This study proposes the valuation of wetland functions as an alternative to the conventional approach to wetland valuation, in order to derive indicators for decision-making in wetland management. It is illustrated that these functions can be valuated in terms of the goods and services they provide to society. Using a functional approach, the functions are identified and the goods and services they provide are explicitly allocated among them; then, the latter are valuated with the Contingent Valuation method. Statistical analysis of the data provides welfare measures that reflect the value of these functions. It is argued that the values of separate functions are more useful in policy-making than their aggregated value.

Long-term strategy for sustainable development: strategies to promote far-sighted action

Given progress in policies for pursuing sustainable development, promoting commitment to thinking and acting more far-sightedly has become the primary strategic challenge. In the face of impatience, selfishness, uncertainty, analytical limitations, and vulnerability, strategies for promoting far-sightedness can be identified by assessing how these obstacles can be overcome. Strategies for creating or rescheduling tangible and deference rewards, realigning performance evaluations, implementing cognitive exercises, framing communications, altering decision-making processes, using self-restraint devices both to resist temptation and to enhance credibility, altering institutions to empower the patient, and stabilizing living conditions are the major categories for identifying and assessing the many strategies which arise out of both ordinary and constitutive policy initiatives.

The benefits of the Kyoto Protocol to developing countries

The Kyoto Protocol relies on incentive-based regulations layered underneath a global cap on net emissions of greenhouse gases. Within the Kyoto Protocol are opportunities and constraints for signatory nations. Of concern to developing nations are the constraints the Kyoto Protocol could place on future growth. We examine the constraints and the opportunities offered to developing countries within the Kyoto Protocol. By identifying the potential costs and benefits the Kyoto Protocol has to offer to developing countries and by examining the incentives each create, we hope to spark serious investigations into ways to minimize the potential costs of entering the Kyoto Protocol and take full advantage of the potential benefits.

Ten years of international scientific cooperation in fisheries,aquaculture and coastal zones: some preliminary lessons

The paper examines preliminary experiences with international scientific cooperation in fisheries, aquaculture and coastal zone issues through 90 projects in successive European Research Framework Programmes (FP4–FP6: 1994–2006). FPs had increasingly ambitious objectives in response to international commitments, such as the Convention on Biological Diversity, the Millennium Development Goals, the Johannesburg Plan of Implementation and dialogue with partner regions. Sustainable aquatic food production in the context of respect for ecosystems was a central concern. Engagement with different social actors and attention to investment in education, people and institutions enabled uptake of research results in education, innovation and some impact. The emphasis in several recent projects on more integrated analyses and knowledge products in the public domain is an encouraging response to the growing crisis of aquatic resource systems. It is suggested that significant up-scaling will be required. This might be done through institutional internalisation and better translation of research results into policy developments supportive of transitions towards sustainable production systems and ecosystem rehabilitation. Capacity building to use research in novel ways and other enabling mechanisms need to be put in place to increase societal and environmental benefits of the research.

A heuristic for setting effective standards to ensure global environmental sustainability

Most environmental professionals and decision-makers, and certainly the public at large, hold the view that the integrity of earth’s natural environment will be conserved for posterity and sustainable development achieved if all the nations rigorously enforced their environmental and emission standards. It is argued in this paper that this view, sincerely held by many as an “axiomatic truth,” is mistaken and misplaced. This is because as a biogeochemical entity the Earth has limited self-regenerative capacity (SRC) to cope with anthropogenic pollution, and all kinds of environmental problems ensue when that limit is exceeded. Indeed, mounting environmental problems now occurring on all fronts amply testify to the fact that the limit has already been exceeded. They also provide necessary and sufficient proof that environmental and emission standards have been woefully inadequate for protecting earth’s natural environment and life-support systems. It is argued that true global environmental sustainability will be achieved, paving the way to true global sustainable development, if and only if global environmental and emission standards are set so that global anthropogenic pollution does not exceed the limit of earth’s natural SRC to cope with such pollution. These and related issues are discussed in this paper. A simple mathematical model using basic mathematics is also presented to explain how the phenomenon of “positive feedback” works in some of the environmental problems to exacerbate environmental degradation and progressively to erode nature’s SRC.

Participatory Integrated Assessment in local level planning

The topic is introduced by a short but critical discussion of criteria and needs of Participatory Integrated Assessment (PIA) and participatory local planning. This paper depicts differences of participation in Integrated Assessment and in local level planning but provides also conditions and ideas how PIA can be used for local planning including implementation. A small review of PIA and participation in planning illustrates the relevance of PIA in a knowledge economy trying to adopt principles of good governance. A better incorporation of participatory research into local level planning seems to be crucial. The applicability of PIA in practices leading to participatory monitoring and evaluations are discussed. The outcomes of the paper show that possibilities exist for integrating PIA and participatory monitoring and evaluation into the implementation of the European Water Framework Directive (WFD). PIA adds local information to water management planning and supports individual learning processes. The setting up of such a monitoring and evaluation system may contribute towards a transparent implementation of the WFD, it enhances commitment of citizens towards local government planning and eventually it increases self-determination of citizens, a major objective of good governance.

Policy sciences contributions to analysis to promote sustainability

The policy sciences, in offering the most comprehensive approach to policy analysis and the sociopolitical processes that shape policy outcomes, is particularly appropriate for guiding the analysis required to promote sustainability. This article presents the main components of the policy sciences framework and demonstrates its potency in the crucial task of deepening the problem definitions required to select and enact policies to promote sustainability. As such, it provides background for the policy sciences articles of this special feature.

Urban water-related environmental transitions in Southeast Asia

This article reviews water-related urban environmental conditions in Southeast Asia. It argues that the development of urban environmental challenges in the region follows a unique pattern compared with those experienced in the now developed world. The new pattern is defined by the so called time–space telescoping of the development process. The process of time–space telescoping reduces the levels of income at which environmental challenges emerge and forces their appearance in a simultaneous fashion, as sets of problems. During previous eras, cities experienced sequential environmental transitions. Urban water-related environmental burdens emerged on local scales and expanded geographically and temporally in impact, with growing levels of affluence. Moreover, certain environmental challenges appeared later in economic growth because the technologies and practices that induced these problems emerged at higher levels of income. The article has two main findings. First, except for wealthy urban centers, for example Singapore, cities in the region are experiencing multi-scaled water burdens simultaneously. Second, low-income and middle-income cities are experiencing burdens at lower levels of income than did their contemporaries in the north.

Building sustainable & resilient communities: a balancing of community capital

Working toward sustainable community is a complex task for communities especially given the ambiguous nature of implementing the concept of sustainable development. However, by working to understand the nature of community capital, administrators can begin to move beyond bottom line thinking toward a more comprehensive and collective view of community. This paper presents a theoretical framework that helps municipal decision makers begin collecting information they need to help them build sustainable and resilient communities.

Application of fuzzy models to assess susceptibility to droughts from a socio-economic perspective

By combining the concepts of environmental stress, state susceptibility and environmental crisis, “Security Diagram” (SD) provides a quantitative approach to assessing environmental change and human security. The SD is a tool that clearly presents in a diagram the security situation of a population or region affected by a particular environmental crisis. Its underlying concept emphasises that the higher the level of environmental stress and socio-economic susceptibility, the higher the probability of the occurrence of crisis. Focusing on drought, this study analyses the susceptibility of case study regions in India, Portugal, and Russia from a socio-economic perspective. A conceptual framework of socio-economic susceptibility is developed based on the economic development theories of modernisation and dependency. Fuzzy set theory is used to generate susceptibility indices from a range of national and sub-national indicators, including financial resources, agricultural dependency and infrastructure development (for economic susceptibility), and health condition, educational attainment and gender inequality (for social susceptibility). Results indicate that socio-economic susceptibility over the period 1980–1995 was highest in India, followed by Russia and (since 1989) lowest in Portugal. Globalisation is likely to contribute to changes in the level of socio-economic susceptibility over time. Moreover, specific social and economic structures unique in each country (e.g., the role of women in society in India, the socialist legacy in Russia) may explain differences in susceptibility between the case study regions.

The ecological footprint: an exhibit at an intergenerational trial?

This paper aims at assessing the extent to which the ecological footprint indicator (EF) can be regarded as an exhibit allowing an intergenerational trial about the use of natural resources. For that purpose, we examine various criticisms questioning the relevancy of EF measures for the study of environmental justice between generations. We explore the difficulties raised by the physical—and highly aggregated—nature of EF measures, as well as problems related to the number, the possible non-existence, and the tastes of future generations. The extent to which postulates on nature’s regeneration and technological progress affect the significance of EF studies is also discussed. It is concluded that those criticisms, by identifying various weaknesses of EF measures for the study of intergenerational justice, point to several crucial refinements of existing EF-based analyses.

The environmental impact of industrialization in East Asia and strategies toward sustainable development

The East Asian economy has been growing fast in recent years, and environmental stresses are building up rapidly. Transboundary air pollution, water shortages, drinking water contamination, freshwater and marine pollution, deforestation, climatic disasters, and other environmental problems are becoming serious threats to the well-being of people in this densely populated region. The ESI (environmental sustainability index) reported by the World Economic Forum in 2005 is a good indicator of the environmental status of the region; most East Asian countries ranked at the bottom. East Asia is not moving toward a sustainable society, and the environment will not sustain the current rate of economic development for long. The traditional culture of East Asia used to be sustainable, so we can learn much from our traditions. Land use should be planned from an ecological point of view so as to best preserve the land’s productivity and stability. There should be definite goals as to where and how much to preserve the three important ecological bases: forests, coastal wetlands and agricultural farms. The forest is the base for the terrestrial ecosystem, including flood control, water resources, and climate; the coastal wetland is the base for the marine ecosystem; farmland is the base for producing food. Within these defined goals, limits should be set on how much land can be utilized for activities like urban development, manufacturing, and recreation. Limits on the pollution load resulting from such activities should be set so as not to irreversibly damage the environment. Economic development should be planned to allow the use of energy and resources only after satisfying these constraints.

Towards a spatially explicit and quantitative vulnerability assessment of environmental change in Europe

Over the next century, society will increasingly be confronted with the impacts of global change (e.g. pollution, land use changes, and climate change). Multiple scenarios provide us with a range of possible changes in socio-economic trends, land uses and climate (i.e. exposure) and allow us to assess the response of ecosystems and changes in the services they provide (i.e. potential impacts). Since vulnerability to global change is less when society is able to adapt, it is important to provide decision makers with tools that will allow them to assess and compare the vulnerability of different sectors and regions to global change, taking into account exposure and sensitivity, as well as adaptive capacity. This paper presents a method that allows quantitative spatial analyses of the vulnerability of the human-environment system on a European scale. It is a first step towards providing stakeholders and policy makers with a spatially explicit portfolio of comparable projections of ecosystem services, providing a basis for discussion on the sustainable management of Europe’s natural resources.

The influence of climate and dam construction on the Ibera wetlands, Argentina

The purpose of this work is to assess the impact on the Esteros del Ibera wetland ecosystem caused by the Yacyreta dam, a large hydroelectric power plant on the Parana River, Argentina, in comparison to other factors of environmental change. The project of the dam started around 1970. The power plant began operating in 1994. In 1989, the neighboring Ibera wetland ecosystem showed a substantial increase in the water level for which several different causes were conceivable, including climate change and the dam construction. We analyzed all existing hydrometeorological data and studied other changes that were observed in this ecosystem. A water balance model was used to analyze different scenarios. Increased groundwater inflow, generated since the construction of the dam, appears to be affecting the wetland more than any other factor. The study has implications for the assessment of global and regional consequences of building dams.

Accounting for the mismanagement of tropical nearshore fisheries

The underlying reason for the mismanagement of tropical nearshore fisheries is the implementation of policies and programs based on Western models and approaches, coupled with an inability and/or unwillingness to consider non-Western alternatives of empirically proven value. Such attitudes are embedded in donor and development agency behavior, and are demonstrated by the temperate bias in conventional approaches to fisheries education and management, with a corresponding lack of understanding of tropical milieux, and in the persistence of various prejudices. Adaptive Management, The Ecosystem Approach, Local Knowledge, and Protected Areas are discussed from the perspectives of Western models and pre-existing Pacific Island systems as alternative models. Given the parlous condition of the global environment and resources, the best non-Western pre-existing models and Western approaches must be blended to provide sustainable solutions.

Europe–Middle East–North Africa cooperation for sustainable electricity and water

This report summarizes the results of two studies of electricity supply for Europe (EU), the Middle East (ME) and North Africa (NA) up to the year 2050. It shows that a transition to competitive, secure and sustainable supply of electricity and water is possible using renewable energy sources, efficiency gains and fossil fuel backup for balancing power. A strong cooperation between the EU and MENA for the market introduction of renewable energy and the interconnection of the electricity grids by high-voltage direct-current transmission are keys to the success and survival of the whole region. However, the necessary measures will take at least two decades to become effective. Therefore, adequate policy and economic frameworks for their realization must be introduced immediately. The importance of sustainable energy for the security of freshwater supplies in MENA is also described.
