The global dimension of water governance: Nine reasons for global arrangements in order to cope with local water problems

Where water problems extend beyond the borders of local communities, the catchment area or river basin is generally seen as the most appropriate unit for analysis, planning and institutional arrangements. In this paper it\ud is argued that addressing water problems at the river basin level is not always sufficient. It is shown that a substantial part of today’s water issues carries a (sub)continental or even global dimension, which urges for a governance approach that comprises coordination and institutional arrangements at a level above that of the river basin. This paper distinguishes and reviews nine developments that support this argument: • Local issues of water scarcity and flooding will be enhanced or weakened by human-induced global climate\ud change.\ud • Local problems of water pollution are often intrinsic to the structure of the global economy.\ud • There is a growing presence of multinationals in the drinking water sector.\ud • Several national governments are developing plans for large-scale inter-basin water transfers.\ud • An increasing number of water-short countries seek to preserve their domestic water resources through the\ud import of water in virtual form.\ud • Global trade in water-intensive commodities offers the opportunity of global water saving if this trade is\ud from countries with high to countries with low water productivity.\ud • The water footprints of individual people are increasingly externalised to other parts of the world, so that\ud many local water problems are strongly related to consumption elsewhere.\ud • Some people around the world have comparatively high water footprints, which raises the question of\ud whether this is fair and sustainable.\ud • Due to its increasing scarcity and uneven distribution across the globe, water is gradually becoming a geopolitical resource, influencing the power of nations.\ud The described developments raise the question of what kind of institutional arrangements could be developed to cope with the global dimension of water issues. A few possible directions are identified in an explorative analysis: an international protocol on full-cost water pricing, a water label for water-intensive products, a disposal tax on goods that will cause water pollution in their waste stage (to be used for pollution prevention and\ud control), international nutrient housekeeping, minimum water rights, maximum allowable water footprints, and tradable water footprint permits

Energy scenario choices: insights from a retrospective review of UK energy futures

Since the 1980s, there has been a shift in energy research. It has shifted from approaches that forecast or project the future to approaches which make more tentative claims and which explore several plausible scenarios. Due to multiple uncertainties in energy systems, there is an infinite amount of plausible scenarios that could be constructed and scenario developers therefore choose smaller, more tangible sets of scenarios to analyse. Yet, it is often unclear how and why this scenario choice is made and how such choices might be improved. This paper presents a retrospective analysis of twelve UK energy scenarios developed between 1978 and 2002. It investigates how specific scenarios were chosen and whether these choices captured the actual UK energy system transition. It finds that scenario choice reflected contemporary debates, leading to a focus on certain issues and limiting the insights gleaned from these exercises. The paper argues for multi-organisation and multi-method approaches to the development of energy scenarios to capture the wide range of insights on offer. Rather than focus on uncertainty in model parameters, greater reflection on structural uncertainties, such as shifts in energy governance, is also required

Synopsis of global scenario and forecasting surveys scenarios in risk habitat megacity (RHM)

The main objective of the paper is to provide a synopsis of global scenario and forecasting surveys. First, the paper will give an overview on existing global scenario and forecasting surveys and their specific scenario philosophies and storylines. Second, the major driving forces that shape and characterise the different scenarios will be identified. The scenario analysis has been provided for the research project Risk Habitat Megacity (HRM) that aims at developing strategies for sustainable development in megacities and urban agglomerations. The analysis of international scenario surveys is an essential component within RHM. The scenario analysis will be the basis and source for the development of own RHM-framework scenarios and for defining specific driving forces of change.scenarios, megacities, risk habitat

The global dimension of water governance: why the river basin approach is no longer sufficient and why cooperative action at global level is needed

When water problems extend beyond the borders of local communities, the river basin is generally seen as the most appropriate unit for analysis, planning, and institutional arrangements. In this paper it is argued that addressing water problems at the river basin level is not always sufficient. Many of today’s seemingly local water issues carry a (sub)continental or even global dimension, which urges for a governance approach that comprises institutional arrangements at a level beyond that of the river basin. This paper examines a number of arguments for the thesis that good water governance requires a global approach complementary to the river basin approach. Subsequently, it identifies four major issues to be addressed at global scale: Efficiency, equity, sustainability and security of water supply in a globalised world. Finally, the paper raises the question of what kind of institutional arrangements could be developed to cope with the global dimension of water issues. A few possible directions are explored, ranging from an international protocol on full-cost water pricing and a water label for water-intensive products to the implementation of water footprint quotas and the water-neutral concept

Modelling and observing urban climate in the Netherlands

Volgens de klimaatscenario’s van het KNMI uit 2006 zal de gemiddelde temperatuur in Nederland in de komende decennia verder stijgen. Hittegolven zullen naar verwachting vaker voorkomen en de intensiteit van met name zomerse buien kan toenemen. In steden zijn de gevolgen van de opwarming extra voelbaar, omdat de temperaturen er door het zogenoemde Urban Heat Island (UHI) effect veel hoger kunnen zijn dan in het omliggende gebied. Zulke periodes met hoge temperaturen gaan veelal gepaard met verslechterde luchtkwaliteit en droogte. Dit alles kan grote gevolgen hebben voor de leefbaarheid en de gezondheid van de bevolking in stedelijke gebieden. Veranderingen in de buienintensiteit beïnvloeden de waterhuishouding van de stad

Literature review of scenario methods. W.P. 5-W.P. 4 D.3 final (version 1)

This document is a literature review of scenario methods elaborated in the frame of ADD TRANS project (2005-2009) . Within this project, WP4 is aimed at the assessment of land use change at the farm level and its impacts on the territory and WP5 is aimed at the elaboration of an integrated approach of land-use changes in livestock farming, natural resources and ecosystems at the landscape level. Both intend to contribute to the renewal of approaches and tools of changes in livestock farming and their environmental consequences from prospective assessments based on modelling and scenarios, to support the policy decision-making process and local governance. When taking an interest in scenario methods and, by the way, in papers that address the theoretical and fundamentals in use in scenarios studies, one faces what Marien (2002) has called a 'very fuzzy multi-field'. But, when structuring future approaches into three modes of thinking: probable (related to predictive mode of thinking), possible (related to eventualities mode of thinking) and preferable (related to visionary mode of thinking), it seems that the great majority of futurists think in only one, or at most two of these three categories (Marien, 2002). Thus, we tackle and depict the wide diversity of scenario methods within the frame of "classical" modes of thinking whilst addressing evolutions of approaches, concerns and objectives. Our literature review of scenario methods highlight the increased interests, when exploring the future, into integrated approaches based on system thinking and participatory approaches, and stress the resulting methodological changes in scenario studies addressing "classical" modes of thinking. In the last part of the review, we address the recent development of new scenario methods in the environmental field. In close reference to sustainability concerns, environmental scenario studies focus more and more on improving the assessment of the links between societal change and ecosystem change from a global to a micro-scale perspective. These scenario methods appear as adaptive combinations of earlier and new approaches, methods, techniques and tools to better address both decision-making and governance processes. We focus on local scale, where interactions between ecosystem functioning and decisions of stakeholders can be concretely modelled, to illustrate such evolution by means of scenario studies combining the use of multi-agent systems and scenario methods encapsulated within a "companion modelling approach".
