If Stationarity is Dead,What Do We Do Now?1

Galloway, Gerald E., 2011. If Stationarity Is Dead, What Do We Do Now? Journal of the American Water Resources Association (JAWRA) 47(3):563‐570. DOI: 10.1111/j.1752‐1688.2011.00550.x Abstract: In January 2010, hydrologists, climatologists, engineers, and scientists met in Boulder, Colorado, to discuss the report of the death of hydrologic stationarity and the implications this might have on water resources planning and operations in the United States and abroad. For decades planners have relied on design guidance from the Interagency Advisory Committee on Water Data Bulletin 17B that was based upon the concept of stationarity. After 2½ days of discussion it became clear that the assembled community had yet to reach an agreement on whether or not to replace the assumption of stationarity with an assumption of nonstationarity or something else. Hydrologists were skeptical that data gathered to this point in the 21st Century point to any significant change in river parameters. Climatologists, on the other hand, point to climate change and the predicted shift away from current conditions to a more turbulent flood and drought filled future. Both groups are challenged to provide immediate guidance to those individuals in and outside the water community who today must commit funds and efforts on projects that will require the best estimates of future conditions. The workshop surfaced many approaches to dealing with these challenges. While there is good reason to support additional study of the death of stationarity, its implications, and new approaches, there is also a great need to provide those in the field the information they require now to plan, design, and operate today’s projects.     

The relationship between economic and carbon footprint changes in EU: The achievements of the EU sustainable consumption and production policy implementation

The Sustainable Consumption and Production policy is a key objective in the renewed European Union (EU) Sustainable Development Strategy (SDS). EU countries implement the targets of Sustainable Consumption and Production policy at different a level. Nevertheless, SDS targets are concerned more with production than consumption side. In addition, analysis of the carbon footprint data, which was supplied by the Global Footprint Network, showed that in all EU countries consumption-based carbon footprint caught-up and exceeded the level of production-based carbon (except Denmark and Estonia) during 1993–2010 period. The significant absolute decoupling in terms of carbon footprint from production-based perspective was observed in Belgium, Denmark, Sweden, Slovakia, Poland, United Kingdom and Germany, meanwhile from consumption-based perspective only in Denmark, Estonia and Germany. Moreover in Spain, Portugal, Italy and Croatia the consumption-based carbon footprint grew faster than economy in general. Results imply that EU should put more focus on consumption side in terms of Sustainable Consumption and Production policy and measures taken. A commitment to reduce the environmental impact from consumption-based perspective should be more addressed covering values and lifestyles.     

Carbon accounting of material substitution with biomass: Case studies for Austria investigated with IPCC default and alternative approaches

There is evidence that the replacement of carbon-intensive products with bio-based substitutes (‘material substitution with biomass’) can be highly efficient in reducing greenhouse gas (GHG) emissions. Based on two case studies (CS1/2) for Austria, potential benefits of material substitution in comparison to fuel substitution are analysed. GHG savings are calculated according to default IPCC approaches (Tier 2 method assuming first-order decay) and with more realistic approaches based on distribution functions. In CS1, high savings are achieved by using wood residues for the production of insulating boards instead of energy. The superiority of material substitution is due to the establishment of a long-term carbon storage, the high emission factor of wood in comparison to natural gas and higher efficiencies of gas-fired facilities.The biomass feedstock in CS2 is lignocellulosic ethanol being used for bio-ethylene production (material substitution) or replacing gasoline (fuel substitution). GHG savings are mainly due to lower production emissions of bio-ethylene in comparison to conventional ethylene and significantly lower than in CS1 (per unit of biomass consumed). While CS1 is highly robust to parameter variation, the long-term projections in CS2 are quite speculative.To create adequate incentives for including material substitution in national climate strategies, shortcomings of current default accounting methods must be addressed. Under current methods the GHG savings in both case studies would not (fully) materialize in the national GHG inventory. The main reason is that accounting of wood products is confined to the proportion derived from domestic harvest, whereas imported biomass used for energy is treated as carbon-neutral. Further inadequacies of IPCC default accounting methods include the assumption of exponential decay and the disregard of advanced bio-based products.     

Effect of illumination regime on life span in <Emphasis Type="Italic">Drosophila melanogaster</Emphasis>

Accelerated aging of Drosophila strains with impaired detoxification of free radicals (Sod) and DNA repair (mus-210) under illumination as compared to the wild type has been demonstrated. In contrast, in a strain carrying a defective homolog of mammalian gene PCNA, the life span increases under conditions of round-the-clock illumination compared to constant darkness. The first review of the possible mechanisms underlying the effect of the illumination regime on the life span is presented, with special emphasis on the roles of the disturbance of normal circadian rhythms, increase in fecundity and physical activity (metabolic rate), and the neuroendocrine control of the insulin/IGF-1 pathway.     

Science,policy and place in volcanic disasters: Insights from Montserrat

This paper presents the results of empirical research on Montserrat, in the British West Indies, undertaken in 2008–2010. It highlights the challenges of managing a crisis that evolved from acute to chronic over a period of fifteen years. In particular, the paper considers the evolution of science and policy over a period of fifteen years in its social and cultural context. It discusses the relationship between different types of evolving knowledges, and the interaction between them. Finally, a reflexive model is introduced to draw attention to some of the challenges of managing the science–policy interface under high uncertainty and high stakes.     

Conservation Focus on Europe: Major Conservation Policy Issues That Need to Be Informed by Conservation Science

Abstract:  Europe is one of the world's most densely populated continents and has a long history of human-dominated land- and seascapes. Europe is also at the forefront of developing and implementing multinational conservation efforts. In this contribution, we describe some top policy issues in Europe that need to be informed by high-quality conservation science. These include evaluation of the effectiveness of the Natura 2000 network of protected sites, implications of rapid economic and subsequent land-use change in Central and Eastern Europe, conservation of marine biodiversity and sustainability of fisheries, the effect of climate change on movement of species in highly fragmented landscapes, and attempts to assess the economic value of ecosystem services and biodiversity. Broad policy issues such as those identified are not easily amenable to scientific experiment. A key challenge at the science–policy interface is to identify the research questions underlying these problem areas so that conservation science can provide evidence to underpin future policy development .     

The Role of Water Doctrines in Enhancing Opportunities for Sustainable Agriculture in Alabama1

Abstract: Alabama is a water rich state. Yet, agriculture is limited in both scale and productivity and the state regularly suffers from drought. Climate variability adds to this paradox even while water users, particularly farmers, have few coping mechanisms. In this paper, we argue that more significant than the water resource itself in Alabama is the governance structure of that resource. The riparian doctrine, as it stands, stymies effective management. The role of water doctrines, and resultant policy, is, therefore, crucial to enhancing decision‐making opportunities for agricultural end‐users in Alabama. After exploring different doctrine types as applied across the states we conclude that a move towards “regulated riparianism” consistent with the American Society of Civil Engineers Regulated Riparian Water Code (2004) would enhance opportunities for both the state and agriculturalists to cope with variable water supply conditions while maximizing environmental benefits. The paper then concludes with a review of the primary objectives of the Water Code and key places where Alabama’s Water Code would need revision to meet these objectives.

Farmers' perceptions of implementation of climate variability disaster preparedness strategies in Central Uganda

This paper examines smallholder farmers' perceptions of the implementation of climate change disaster preparedness strategies in Mpigi district in Central Uganda. Furthermore, existing community early actions against climate change disasters were investigated. Data were collected through semi-structured interviews and focus group discussions at the community level. Using the Statistical Package for Social Sciences version 16, data obtained through semi-structured interviews were subjected to quantitative analysis to generate percentages for several variables and cross-tabulation analyses between selected variables. Farmers perceived prolonged droughts, increased pests and diseases outbreaks in crops and livestock as a consequence of climate change as the major climate change disasters. They considered the implementation of climate change disaster preparedness at community and village level as inadequate. This triggered implementation of various early actions by farmers as responses to climate change disasters. These actions constitute an informal community-based early warning system against climate change disasters.
