    Notes: Abstract Seismic hazard within juvenile rift systems ismodelled by a semi-statistical procedure based onfault segmentation theory. Fault segmentationprovides the physical basis for strong earthquakerecurrence in regions undergoing extension, andtherefore, it may control the position and size of rupture areas for future events. The computercode FRISK (McGuire, 1978) is applied to calculateprobabilistic estimates of ground motion parameters. Six normal fault segments, on average 25 km long, aremodelled as the earthquake sources within the Gulf ofEvia Rift, Central Greece. The position and length ofsegments have been determined from image processing ofremotely-sensed data and field work. FRISK output isdirected to a Geographical Information System (GIS)and a series of high-resolution (0.1 by 0.1 of adegree) digital maps are produced. The results for100 year acceleration (63% not to be exceeded) showa 50% increase in the seismic hazard from previouslyestimated magnitudes. Areas of maximum hazard (over0.4 g) are located on the south coast of the Gulf ofEvia between the towns of Kammena Vourla and Arkitsa. The obtained shape of Peak Ground Acceleration (PGA)contours is slightly elliptical with the long axis ofthe ellipse trending E-W, and symmetric, with respectto the rift axis.

    Notes: Abstract The incorporation of a set ofcomputer-based tools, such as Geographical InformationSystems and physical models, to the field of riskassessment, introduces a new perspective in thevolcanic risk maps production, increasing the analysisand modelling capabilities available through theapplication of conventional methodologies. Amethodology adapted to the requirements andcharacteristics of the new operating environment hasbeen applied at Tenerife island (Canary Islands,Spain) to carry out a study devoted to analyse thesuitability of these tools for near real-timemanagement of volcanic crises. With this in mind, aseries of potential eruption scenarios have beenselected to identify and characterise which elementsat risk would prove most vulnerable against a specificvolcanic phenomenon, depending on the socio-economiccharacteristics of the area affected and the resultingdistribution of the volcanic products. This kind ofinformation is fundamental to update, adapt or produceeffective risk management and emergency plans orprotocols, where the measures to mitigate or fightagainst a specific volcanic disaster have to be taken,incorporating the existing knowledge of the phenomenonbehaviour and taking into account their potentialeffects on the area of interest.

    Notes: Abstract Volcanic catastrophes constitute a majorproblem in many developing and developed countries. Inrecent years population growth and the expansion ofsettlements and basic supply lines (e.g., water, gas,etc.) have greatly increased the impact of volcanicdisasters. Correct land-use planning is fundamental inminimising both loss of life and damage to property.In this contribution Geographical Information Systems(GIS), linked with remote sensing technology andtelecommunications/warning systems, have emerged asone of the most promising tools to support thedecision-making process. Some GIS are presented fortwo volcanic areas in Italy, Mt. Etna and Vesuvius.GIS role in risk management is then discussed, keepingin mind the different volcanic scenarios of effusiveand explosive phenomena. Mt. Etna system covers alarge area (more than 1,000 km2) potentiallyaffected by effusive phenomena (lava flows) whichcause damage to both houses and properties in general.No risk to life is expected. The time-scales of lavaflows allow, at least in principle, modification ofthe lava path by the building of artificial barriers.Vesuvius shows typically an explosive behaviour. Inthe case of a medium size explosive eruption, 600,000people would potentially have to be evacuated from anarea of about 200 km2 around the Volcano, sincethey are exposed to ruinous, very fast phenomena likepyroclastic surges and flows, lahars, ash fallout,etc. Ash fallout and floods/lahars are also expectedin distal areas, between Vesuvius and Avellino,downwind of the volcano. GIS include digital elevationmodels, satellite images, volcanic hazard maps andvector data on natural and artificial features (energysupply lines, strategic buildings, roads, railways,etc.). The nature and the level of detail in the twodata bases are different, on the basis of thedifferent expected volcanic phenomena. The GIS havebeen planned: (a) for volcanic risk mitigation (hazard,value, vulnerability and risk map assessing), (b) toprovide suitable tools during an impending crisis, (c)to provide a basis for emergency plans.

    Assessing alpine plant vulnerability to climate change: a modeling perspective (2000)
    Springer
    Integrated assessment 1 (2000), S. 307-320

    Keywords: climate change ; ecological impact assessment ; alpine and subalpine belts ; plant distribution ; statistical modeling ; local scale ; GIS ; GLM ; Swiss Alps
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract The potential ecological impact of ongoing climate change has been much discussed. High mountain ecosystems were identified early on as potentially very sensitive areas. Scenarios of upward species movement and vegetation shift are commonly discussed in the literature. Mountains being characteristically conic in shape, impact scenarios usually assume that a smaller surface area will be available as species move up. However, as the frequency distribution of additional physiographic factors (e.g., slope angle) changes with increasing elevation (e.g., with few gentle slopes available at higher elevation), species migrating upslope may encounter increasingly unsuitable conditions. As a result, many species could suffer severe reduction of their habitat surface, which could in turn affect patterns of biodiversity. In this paper, results from static plant distribution modeling are used to derive climate change impact scenarios in a high mountain environment. Models are adjusted with presence/absence of species. Environmental predictors used are: annual mean air temperature, slope, indices of topographic position, geology, rock cover, modeled permafrost and several indices of solar radiation and snow cover duration. Potential Habitat Distribution maps were drawn for 62 higher plant species, from which three separate climate change impact scenarios were derived. These scenarios show a great range of response, depending on the species and the degree of warming. Alpine species would be at greatest risk of local extinction, whereas species with a large elevation range would run the lowest risk. Limitations of the models and scenarios are further discussed.

    A Gradient Study of 34 Elements in the Vicinity of a Copper-Nickel Smelter in the Kola Peninsula (2000)

    Notes: Abstract Concentrations of 34 elements determined by ICP mass spectrometry were studied in surface soil and vegetation along a north–south gradient through the ‘Pechenganickel’ smelter complex in Kola peninsula, northern Russia. Strong influence from the smelter was evident for Fe, Co, Ni, and Cu, mainly associated with dry deposition of large particles. Also for As, Se, Mo, Sb, Te, Bi, and Pb the smelter or associated sources appeared to be distinct contributors of contamination consisting presumably of smaller particles. Significant but less distinct effects leading to enhanced concentration levels were observed for P, S, V, Cr, Zn, and Tl. In the case of Mn, Rb, Sr, Cs, and Ba the concentrations in vegetation were generally lower near the source, which may be due to cation exchange with protons or heavy metal cations in the soil and subsequent leaching from the root zone. For Li, Be, B, Na, Mg, Al, Ca, Y, Cd, La, Th, and U no particular influence from the smelter complex was observed. Some characteristic differences observed in element concentrations in different plant species and between different years of Pinus sylvestris needles are discussed. The high concentrations observed for many trace elements in the humus horizon indicates that it acts as an active biogeochemical barrier against downward transport of these elements.

    An Automated Technique for Delineating and Characterizing Valley-Bottom Settings (2000)
    Springer

    ISSN: 1573-2959
    Keywords: valley bottoms ; classification ; mapping ; GIS ; automated techniques

    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Accurate delineation and characterization of valley-bottom settings is crucial to the assessment of the biological and geomorphological components of riverine systems; yet, to date, most valley-bottom mapping endeavors have been done manually. To improve this situation, we developed automated techniques in a Geographic Information System (GIS) for delineating and characterizing valley-bottom settings in river basins ranging in size from approximately 1,000–10,000 km2. All procedures were developed with ARC/INFO GIS software and fully automated in Arc Macro Language (AML). The GRID module is required for valley-bottom delineation and slope calculations; whereas characterization (i.e., measuring the width of the valley-bottom zone) requires Coordinate Geometry (COGO) in the ARCEDIT module. The process requires three inputs: a polygon coverage of the analysis area; an arc coverage of its hydrography, and a grid representing its digital elevation. The AML is designed to operate within a wide range of computer memory/disk space options, and it allows users to customize several procedures to match the scale and complexity of a given analysis area with available computer hardware.

    Notes: Abstract The exposure to CO of schoolchildren was assessed in the town of Northampton, UK, both by direct measurement and by GIS-based activity modelling. Personal measurement of CO showed that exposures when travelling by car were significantly greater than those when walking, although journey times by car were shorter. However, journey exposures had little effect on maximum 8h mean CO exposures. CO concentration fields in the study area were modelled from current traffic flows, and those expected under different traffic management scenarios. These fields were then used, in combination with children's home and school location, and their activity profiles, to simulate frequency distributions of exposure for different transport modes and traffic management scenarios. The results show a large variability in the effect of traffic management interventions, depending on the child's home and school location.

    Notes: Abstract The World Bank has recently published acomprehensive study of environmental and resourceaccounting, covering 103 countries (World Bank1997a). The study concludes that many Sub-Saharan,Northern African and Middle East countries have hadnegative `genuine' saving rates over the last 20years and therefore fail to pass the test of weaksustainability. This paper argues that the Bank'sconclusions depend on a method for computing usercosts from resource exploitation that is challengedby two competing ones (the `El Serafy'-method andthe method of Repetto et al.) and is inferior to oneof its rivals. Resource rents are re-computed usingthe `El Serafy'-method for 14 countries and theSub-Saharan and Northern African and Middle Eastregions. The results are that both regions andalmost all countries either stop exhibiting signs ofunsustainability or their unsustainability can beexplained without having recourse to resourceaccounting. However, for Congo, Ecuador, Gabon,Nigeria, Mauritania and Trinidad and Tobago there isa lesson: These countries did not adequately use theopportunities they were given through their naturalresource endowments and should learn from theirmistake for the future depletion of their remainingreserves of natural resources.

    Transboundary Externalities in the Environmental Transition Hypothesis (2000)

    Notes: Abstract The Environmental Kuznets Curve (EKC) is a hypothesis which implies that it is possible to “grow out of environmental degradation”. Most theoretical models of the EKC relation have not accounted for transboundary and intergenerational externalities nor have empirical studies provided evidence that validates an inverted U shaped relation between environmental degradation and economic growth for pollution problems where the effects are far-displaced or are long-delayed. This paper integrates the theory of transboundary externalities into the most common theoretical framework applied to the EKC hypothesis. It shows that where a significant proportion of the environmental impacts of economic activity occurs outside the territories in which those activities take place, the de-linking of growth and environmental degradation is less likely to happen. This proposition is demonstrated by assuming that decisionmakers have a Nash-type non cooperative strategic behavior.

    The Landscape Ecology of Pastoral Herding: Spatial Analysis of Land Use and Livestock Production in East Africa (2000)

    Notes: Abstract Understanding landscape-scale patterns of herding is critical in identifying and assessing the impacts of pastoral grazing. Here, a general model of herding is developed based on the Sukuma agropastoral system in the Rukwa Valley, Tanzania. Using this conceptual framework, the factors affecting the maximum distances herds travel from home and the distribution of grazing around pastoral settlements are examined. The distribution of dry season water structured the landscape-scale distribution of grazing throughout the year, not just during the dry season. Water availability strongly affected the distances herds ranged from home in the dry season and the distribution of grazing around pastoral settlements throughout the year. Associations between cattle productivity and herding practices were also examined. The effects of traveling further from home, keeping cattle in large herds, and using/living in areas of high settlement densities were examined on the following measures of productivity: intake rates, foraging behavior, milk yields, and body conditions. Cattle from larger herds were observed to walk more while actively foraging and engage in more walking bouts (taking ten steps without taking a bite). The increased walking of large herds may explain why they range farther from home and highlight the importance and ubiquity of herd splitting among pastoralists. However, herd size effects were not apparent in intake rates or milk yields. Milk yields were negatively affected by traveling farther from home. These data demonstrate substantial variability within herding populations and show interesting similarities with herding systems in substantially more arid areas.
