    An extensive fish sampling and tagging program was conducted on the Snare River, Northwest Territories, in order to collect baseline data on the fish populations in sections of the river altered by hydroelectric projects. Fish populations were sampled from May to July 1977 in five sections of the river that were influenced by development of hydropower at three dams currently on line; 530 tagged fish were also released. The biweekly catch composition in experimental gill nets for each study area and the catch per gill net mesh size are presented for walleye (Stizostedion vitreum), lake trout (Salvelinus namaycush), lake whitefish (Coregonus clupeaformis), lake cisco (Coregonus artedi), northern pike (Esox lucius), white sucker (Catostomus commersoni), and longnose sucker (Catostomus catostomus). Age-specific data on length, weight, age, sex, and maturity are also included. 7 refs., 12 figs., 42 tabs

    It is well documented that changing hydrological conditions impact delta ecosystems. Such changes can also affect local inhabitants who have historical connections to the area and its resources. During the summer of 2003 a multifaceted paleo-environmental project was initiated to reconstruct the frequencies of floods and droughts in the Slave River Delta (SRD), Northwest Territories, Canada. The project goal is to forecast future hydrological and ecological conditions in the SRD in light of anticipated climate change and increasing demand on water resources. With the intent of expanding the climate history of the SRD, this particular aspect of the project will employ white spruce tree-ring chronologies constructed from six sites visited within the delta. Work is currently in progress to build a master chronology estimated to span over 300 years. In addition, a climate model for the SRD is also being developed and will be highlighted.

    Suspended sediment and water samples collected from twelve major rivers in the Northwest Territories were analyzed for aliphatic hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) to assess the sources and transport of hydrocarbons entering the Arctic Ocean. Three stations on the Mackenzie River and one station near the mouth of eleven other northern rivers were selected for sampling. Samples were collected on the Mackenzie River on four occasions to characterize spring, summer and fall flow conditions and once on the remaining eleven rivers during high flow conditions. The Mackenzie River is distinctively different then the other eleven rivers. Naturally occurring hydrocarbons predominate in the river. These hydrocarbons include biogenic alkanes, diagenic PAHs, petrogenic alkanes, and PAHs from oil seeps and/or bitumens. Anthropogenic inputs of PAHs are low as indicated by low concentrations of combustion PAHs. Alkyl PAH distributions indicate that a significant component of the lower molecular weight PAH fraction is petrogenic. The majority of the high molecular weight PAHs, together with the petrogenic PAHs have a principal source in the Mackenzie River

    Drought is a component of many ecosystems in North America causing environmental and socioeconomical impacts. In the ongoing context of climatic and environmental changes, drought-related issues are becoming problematic in northern Canada, which have not been associated with drought-like conditions in the past. Dryer than average conditions threatens the energy security of northern canadian communities, since this region relies on the production of hydroelectricity as an energy source. In the North Slave Region of Northwest Territory (NWT), water levels and streamflows were significantly lower in 2014/2015. The Government of the NWT had to spend nearly $50 million to purchase diesel fuel to generate enough electricity to supplement the reduced power generation of the Snare River hydroelectric system, hence the need to better understand the multi-decadal variability in streamflow. The aims of this presentation are i) to present jack pine and white spruce tree-ring chronologies of Southern NWT; ii) to reconstruct past streamflow of the Snare River Basin; iii) to evaluate the frequency and magnitude of extreme drought conditions, and iv) to identify which large-scale atmospheric or oceanic patterns are teleconnected to regional hydraulic conditions. Preliminary results show that the growth of jack pine and white spruce populations is better correlated with precipitation and temperature, respectively, than hydraulic conditions. Nonetheless, we present a robust streamflow reconstruction of the Snare River that is well correlated with the summer North Atlantic Oscillation (NAO) index, albeit the strength of the correlation is non-stationary. Spectral analysis corroborate the synchronicity between negative NAO conditions and drought conditions. From an operational standpoint, considering that the general occurrence of positive/negative NAO can be predicted, it the hope of the authors that these results can facilitate energetic planning in the Northwest Territories through

    Winter roads constitute an important part of the transportation network in the MacKenzie Delta, the Yellowknife area, and between the MacKenzie Highway and the Canol Road. Climatic changes in the MacKenzie Valley will alter the probabilities of ice cover thickness and duration, impacting on the periods when ice road river crossings are viable. Stochastic models were developed to generate air temperature and precipitation data to analyze climate impacts on when ice road crossing of the MacKenzie River at Norman Wells is feasible. The data were employed to simulate river ice growth and decay. Several general circulation models were employed to determine the impacts of climatic change on the ice regime. For precipitation simulation, the occurrence of wet or dry days was determined from Markov chain transition probabilities. In general, the Goddard Institute of Space Studies (GISS) model predicted the largest increase in monthly precipitation and the Oregon State University (OSU) model predicted the least changes. The various scenarios indicated that the duration for vehicular traffic over ice will be significantly reduced, compared to present day Norman Wells ice crossing operation. For 20 tonne vehicles, the current duration for safe crossing averages 169±14.6 days per year, while for the OSU scenario it will be reduced to 148±14.7 days, is further reduced to 127±24.9 days for the GISS scenario, and drops to 122±21.7 days for the GFDL (General Fluid Dynamics Laboratory) scenario. 5 refs., 1 fig

    The practical and legal issues regarding business operations in the Northwest Territories were discussed for the benefit of any enterprise wishing to conduct business in the territory. The non-renewable resources in the North are greatly responsible for the economic development in the Northwest Territories. Yellowknife was established in 1930's to service the gold mines and is now the service centre for Canada's only diamond mine located in the tundra one hour by air from Yellowknife. Other major oil and gas discoveries include Norman Wells along the Mackenzie River and the Beaufort Delta Region. In addition, new oil and gas has been discovered near Fort Liard. There is no legislation governing businesses operating in the oil and gas industry specifically, but several Acts exist where general applications would apply. This paper described the demographics of the territory and the types of government. Band councils play a significant role in local government. Much of the land in the Northwest Territories is the subject of land claims or has been transferred to indigenous people as part of settled land claims. A socio-economic agreement signed in 1996 ensures a certain percentage of northern suppliers, northern resident employees and aboriginal employees in both the construction and operation of the BHP mine. An even more demanding agreement was signed for the Diavik Diamond mine in 1999. The registration and licensing requirements that the government of the Northwest Territories imposes on businesses were described with emphasis on the Business Corporations Act, the Business License Act and the Worker's Compensation Act. Employee issues were also discussed as they relate to the Canada Labour Code, the Employment Standards Regulation, Fair Practices Act, and the Payroll Tax Act. Other regulatory requirements which would apply to the oil and gas industry include the Safety Act, the Motor Vehicles Act

    This study researched existing recycling systems, presented pertinent data on the beverage and transportation industries, and evaluated the potential of recycling beverage bottles and cans in the Northwest Territories. The study first describes the history and existing concepts of recycling, provides a general description of recycling methods with advantages and disadvantages, and highlights particular approaches taken by other provinces. Markets for the Northwest Territories are also discussed, including the potential of recoverable material, anticipated recovery rates, transportation to markets, and present recycling operations. Three strategies are identified for the southwest, northwest, and the eastern Region. Recycling is preferred for aluminium cans, glass beer bottles, plastic bottles, and glass wine and liquor bottles in that order. The report recommends a limited program for aluminium cans and beer bottles to begin immediately. Beer bottles should be refilled either in Alberta or the Northwestern Territories and aluminium cans should be compacted and shipped to recycling markets in southern Canada or the United States. The program should first be implemented in areas serviced by Alberta and accessible by truck or barge from Hay River. A program implementation plan is also included. 8 refs., 2 figs., 14 tabs.

    The Northwest Territories Power Corp. is a crown corporation with the responsibility to generate, transform, transmit, distribute, deliver, sell and supply electrical and heat energy throughout the Northwest Territories on a safe, economic and reliable basis. The Corporation distributes electricity directly to the consumer in most of the 52 communities it serves. It also supplies electricity on a wholesale basis to two distributing utilities which retail electricity to customers in Yellowknife and Hay River, Northwest Territories. The Corporation consists of 48 separate power systems and serves a population of 67,000 with a total load of about 90 megawatts. This report presented highlights of the 1999 safety program which included vehicle safety, safe oil transfer and contractor safety. In addition, the report highlighted the restoring of power to Sanikiluaq after the plant was destroyed by fire. Emergency measures were put into effect and power was restored in record time. In 2000, the Corporation received approval for the renewal of three Snare hydro dam licenses. In addition, new plant construction in Clyde River and Paulatuk began in the summer of 1999. The $5 million program to replace the existing cable splices on the 140 km Snare transmission line was also completed. This report also included the company's balance sheets which presented the financial position of the Corporation and the results of its operations and the changes in cash flow for the year. The net income for 1999/2000 would have been $12.1 million, the highest net income in the Corporation's history, if not for the spending of $0.4 million on its Y2K plan, and an allowance of $1 million restructuring costs to allow the Nunavut Territory to operate and manage their own electrical utility. The net earnings therefore, after considering these one-time expenditures for 1999/2000, were $10.7 million, a decrease of $0.8 million from the 1998/1999. tabs., figs.

    Recent trends in environmental assessment theory and practice indicate a growing concern with collaboration and learning. Although there are few examples of the institutional, organizational, and socio-political forms and processes required to foster this collaboration and learning, the establishment of an environmental planning, management, and assessment regime in Canada's Northwest Territories offers useful insights. Consequently, this paper identifies and examines the institutional, organizational, and socio-political conditions that have encouraged more collaborative forms of environmental assessment practice in the Northwest Territories. Key issues highlighted include: (1) the development of decentralized regulatory organizations more responsive to changing circumstances; (2) strategies for more effective communication and participation of community interests; (3) efforts to build a collaborative vision of economic and social development through region-specific land use plans; (4) the integration of knowledge frameworks; and (5) a concern with the capacity required to encourage effective intervention in the assessment process

    Growth of natural resource development in northern Canada has raised concerns about the effects on downstream aquatic ecosystems, but insufficient knowledge of pre-industrial baseline conditions continues to undermine ability of monitoring programs to distinguish industrial-derived contaminants from those supplied by natural processes. Here, we apply a novel paleolimnological approach to define pre-industrial baseline concentrations of 13 priority pollutant metals and vanadium and assess temporal changes, pathways and sources of these metals at a flood-prone lake (SD2) in the Slave River Delta (NWT, Canada) located ~ 500 km north of Alberta's oil sands development and ~ 140 km south of a former gold mine at Yellowknife, NWT. Results identify that metal concentrations, normalized to lithium concentration, are not elevated in sediments deposited during intervals of high flood influence or low flood influence since onset of oil sands development (post-1967) relative to the 1920–1967 baseline established at SD2. When compared to a previously defined baseline for the upstream Athabasca River, several metal-Li relations (Cd, Cr, Ni, Zn, V) in post-1967 sediments delivered by floodwaters appear to plot along a different trajectory, suggesting that the Peace and Slave River watersheds are important natural sources of metal deposition at the Slave River Delta. However, analysis revealed unusually high concentrations of As deposited during the 1950s, an interval of very low flood influence at SD2, which corresponded closely with emission history of the Giant Mine gold smelter indicating a legacy of far-field atmospheric pollution. Our study demonstrates the potential for paleolimnological characterization of baseline conditions and detection of pollution from multiple pathways in floodplain ecosystems, but that knowledge of paleohydrological conditions is essential for interpretation of contaminant profiles. - Highlights: • We examine metal depositional history at a

    In the past decade, many jurisdictions have attempted to estimate quantities and types of hazardous wastes generated within their boundaries. Similar studies done in the Northwest Territories (NWT) are out-of-date, incomplete or specific to only one type of waste or geographical location. In 1990, an industry, business and community survey was conducted to determine types and quantities of hazardous wastes generated in the NWT and currently used disposal methods for these wastes. The survey revealed that 2,500 tons of hazardous wastes were generated each year, including waste oil and petroleum products, fuel tank sludges, acid batteries, spent solvents, antifreeze an waste paint. In many regions, disposal of these wastes may be routine, but waste disposal in arctic and subarctic regions presents unique difficulties. Severe climate, transportation expense, isolation and small quantities of waste generated can make standard solutions expensive, difficult or impossible to apply. Unique solutions are needed for northern waste disposal. The aim of this paper is to give an overview of low-cost, on-site or local hazardous wastes disposal options which can be applied in Canada's NWT and also in other arctic, remote or less-developed regions

    Full Text Available This article aims to show that the establishment of a rural area as a cutout for implementation of public policies for development needs to consider the configuration of the urban network of the municipalities that compose it, identifying what are the hierarchical relationships between the municipalities that make up the territory and if the most dynamic centers radiate influence to the whole. We present the case study of the Northwest Territory of Minas, where were identified various limits for the implementation of territorial development policies. In this article it is shown that such limits are manifested largely because the territory groups municipalities that have different polarizations and establish differentiated functional relationships within the regional urban network. It was found that in this territorial clipping are articulated different social production systems and that the delimitation of the territory does not match even with the regionalization of state and federal agencies.

    This report was commissioned by the Government of the Northwest Territories to determine whether current approaches to electrical system management in the NWT serve the public interest with respect to assuring security of supply, quality, reliability and cost of service, affordability of rates, responsiveness to client needs, adaptability to changing service conditions, and return on public investment. In assessing the ability of the current regime to serve the evolving needs of the people of the NWT, authors of the report also examined recent developments in other jurisdictions, significant issues affecting operation of the Northwest Territories Power Corporation (NTPC), the feasibility of privatization, alternative energy sources, the potential impact of the Mackenzie Valley gas pipeline and hydro resource development. Recommendations include (1) restructuring the NTPC, (2) giving the NTPC a distribution monopoly for all currently served locations, (3) requiring the purchase of alternative energy, (4) repealing the Public Utilities Act, (5) resolving stranded asset issues by amending the Cities, Towns and Villages Act, (6) establishing two rate zones (hydro and other) and the appropriate rates for each, (7) awarding natural gas distribution franchise rights to the NTPC for all NWT communities not currently serviced by others, (8) opening future and additional electric power generation to competition, provided that all technical requirements established by the operating utilities are met, and (9) ensuring that any and all debts associated with Nunavut be removed from NTPC books before the end of FY 2001. 19 refs., tabs., 5 appendices.

    Natural Resources Canada (NRCan) contracted Hatch Associates to conduct seven one-day resource recovery sessions across Canada. The focus of the consultations was to identify opportunities, barriers and demonstration projects to facilitate resource recovery in different urban, rural and northern communities in Canada for the industrial, institutional and post-consumer sectors. These sessions are a first step in helping Canada identify economically-driven resource recovery activities that are environmentally and socially sustainable. This report describes the outcome of a meeting in Yellowknife in the spring of 2002 which involved 16 participants including resource recyclers, the City of Yellowknife, Diavik Diamonds, the government of the Northwest Territories, local entrepreneurs, a landfill operator, a gold mine undergoing environmental rehabilitation, and citizens including an Inuit Elder. The participants identified the following priorities for resource recovery: metal tanks at the Giant Mine, scrap metal at Giant Mine, waste paper, waste oil from vehicles, hazardous waste, arsenic trioxide, and waste packaging. The main barriers to resource recovery in Yellowknife are transportation costs, lack of volumes, the collection/storage infrastructure, and the fact that life cycle and social environmental costs are not included in the costs of products. Several recommendations were proposed to improve resource recovery, including charging a small fee for access to the salvage section of the Yellowknife landfill, charging a fee for garbage over a certain weight, or providing recycling bins everywhere and imposing a fine for disposal of recyclables. tabs.

    The effectiveness of in-situ bioremediation as a means of cleaning up fuel spills in Arctic regions is demonstrated by a case study involving a former fuel tank farm site at Hall Beach, Northwest Territories. An in-situ treatment method, based on the theory of a completely mixed batch wastewater system, was used in this instance. The treatment centred around a commercial floating aerator, which was installed in the pond to provide oxygen. Pre-calculated amounts of nutrients in the form of ammonium chloride and sodium phosphate were also added. The treatment was repeated in the following thawing season to verify initial results. The study is still ongoing; analysis results of the samples collected during the second season are not yet available. However, initial results looked promising and were consistent with what would be expected of increased biological activity. 4 figs

    In 1991, an oil spill was discovered in Bluefish Creek near Fort Norman, Northwest Territories. It was estimated that the spill was between 50 to 70 years old. The spill was discovered in an excavated area that appeared to be a drilling sump. The old spill exhibited an unusual occurrence of patterned partitioning of translucent wax-like material. Gas chromatography found the substance to be consistent with a paraffin based crude oil similar to Norman Wells crude oil. It is possible that Norman Wells crude was used for drilling purposes at the site. It is not likely that the Bluefish wells were the source of the oil because they were both dry holes and there were no records of hydrocarbons being encountered during drilling. Imperial Oil Resources (NWT) Ltd., and Fort Norman Band have made joint efforts in removing 118 barrels of oily debris and have successfully restored the site. 12 refs., 4 figs.

    Proterozoic sequences associated with major unconformities are potential uranium metallogenic provinces. Late Aphebian to Paleohelikian Dubawnt Group contintental clastic sedimentary and subaerial alkaline volcanic rocks and underlying Archean gneisses, District of Keewatin, Northwest Territories, represent one such uraniferous metallogenic province. Three types of uranium mineralization are present in the eastern Baker Lake basin, which extends from Christopher Island at the eastern end of Baker Lake southwestwards to the western limit of Thirty Mile Lake. The three uranium associations are: 1) fracture controlled mineralization in the Dubawnt Group and basement gneisses (U-Cu-Ag-Au-Se or U-Cu-Pb-Mo-Zn), 2)diatreme breccia mineralization in basement gneisses (U-Cu-Zn), and 3) impregnation and microfracture mineralization in altered arkose peripheral to lamprophyre dykes(U-Cu-Ag). Hydrothermal fracture related mineralization is controlled by northwest- and east-northeast-trending fault-fracture zones. Diatreme breccia mineralization results from the channelling of groundwaters through highly permeable brecciated gneiss. Mineralization within the altered Kazan arkose peripheral to alkaline dyke complexes formed by a two stage process. Iron and copper sulphides and silver were deposited within the outer portions of the thermal aureole in response to a temperature and Eh gradient across a convective cell created by the thermal anomaly of the dyke complex. The epigenetic sulphide mineralization subsequently provided the reducing environment for precipitation of uranium from groundwater. All three uranium associations show a close spatial distribution to the basal Dubawnt unconformity. The lithological and structural relationships of the Dubawnt Group rocks, types of mineralization and associated alteration assemblages are strikingly similar to the Beaverlodge district, Saskatchewan.

    Tuberculosis (TB) is an important public health problem in the Northwest Territories (NWT), particularly among Canadian Aboriginal people. To analyse the transmission patterns of tuberculosis among the population living in the NWT, a territorial jurisdiction located within Northern Canada. This population-based retrospective study examined the DNA fingerprints of all laboratory confirmed cases of TB in the NWT, Canada, between 1990 and 2009. An isolate of each lab-confirmed case had genotyping done using IS6110 Restriction Fragment Length Polymorphism. DNA patterns were assigned to each DNA fingerprint, and indistinguishable fingerprints patterns were assigned a cluster. Social network analysis (SNA) was used to examine direct linkages among cases determined through conventional contact tracing (CCT), their DNA fingerprint and home community. Of the 225 lab-confirmed cases identified, the study was limited to 195 subjects due to DNA fingerprinting data availability. The mean age of the cases was 43.8 years (±22.6) and 120 (61.5%) males. The Dene (First Nations) encompassed 120 of the cases (87.7%), 8 cases (4.1%) were Inuit, 2 cases (1.0%) were Metis, 7 cases (3.6%) were Immigrants and 1 case had unknown ethnicity. One hundred and eighty six (95.4%) subjects were clustered, resulting in 8 clusters. Trend analysis showed significant relationships between with risk factors for unemployment (p=0.020), geographic location (p≤0.001) and homelessness (p≤0.001). Other significant risk factors included excessive alcohol consumption, prior infection with Mycobacterium tuberculosis and prior contact with a case of TB. This study demonstrates how DNA fingerprinting and SNA can be additional epidemiological tools, along with CCT method, to determine transmission patterns of TB.

    Monitoring surveys of bird abundance and distribution were conducted in 1990 at McKinley Bay in the Northwest Territories, the site of a winter harbour for drillships and the proposed location for a major year-round support base for oil and gas exploration. Primary objectives of the survey were to determine whether diving duck numbers had changed since the initial phase of the study from 1981-1985, and to provide additional baseline data on natural annual fluctuations in diving duck numbers. Three aerial surveys at each bay were carried out using techniques identical to those in previous years. On 5 August 1990, when survey conditions were considered best of the three surveys, more than twice as many diving ducks were found in McKinley Bay and Hutchinson Bay than on average during the five years of 1981-1985. Old squaw and scooters comprised ca 90% of the diving ducks observed, and both species showed significant increases in numbers. The increase in abundance of diving ducks was likely unrelated to industrial activity in the area since a similar increase occurred in the control area, Hutchinson Bay. Many factors, including both environmental factors such as those affecting nesting success and timing of the moult, and factors related to the survey methods, could be involved in causing the large fluctuations observed. 9 refs., 8 figs., 10 tabs.

    Canada's fastest growing regional market is the Northwest Territories (NWT) due to the significant amount of private-sector investment injected into exploration and development of natural gas and diamonds. The proposed development of a pipeline from the Mackenzie Delta to southern markets has captured attention, and its indirect benefits could provide a huge payoff for the NWT. Other sectors such as hydro-electricity, telecommunication services and tourism are expected to benefit. Important questions must be answered by policy makers, such as the likelihood of sustaining the economic boom and keeping the gains in the NWT rather than flowing south. The author argued that the economic boom will have staying power, since price conditions have improved, and the discovery of diamonds has attracted diamond development activities. Aboriginals are increasingly seeking participation in resource development. Five major challenges were identified: diversification beyond natural resources, infrastructure, labour shortages, impact on the environment, and high costs of living and doing business coupled with concerns about regulation. It was suggested that although the federal government is helping, the NWT government must take control of its own destiny. Resource royalties are not sufficient, and existing tools to create increased fiscal room must be investigated. Debt financing must be addressed to solve some near-term challenges. In addition, the private sector must be engaged. refs., tabs., figs

    The route for the proposed Mackenzie Valley gas pipeline in the Northwest Territories includes areas that are known for widespread landsliding. Natural Resources Canada initiated a landslide mapping project in an effort to develop a synthesis of the types, regional distribution, and controlling factors of landslides in the region. The study area is covered by unconsolidated sediments dominated by morainal, lacustrine, and alluvial deposits. Three types of permafrost were mapped, notably continuous, extensive discontinuous, and intermediate discontinuous. A preliminary inventory of 1,807 landslides and other natural terrain hazard features were identified by air photo interpretations. The landslide limits were digitized and catalogued in the Mackenzie Valley landslide spatial database. Several attributes were recorded for each landslide feature, including unique identifiers, landslide type, size, location, morphological parameters, and relative age. The landslide distribution was then characterized. The results indicate an average density of one landslide per 5 km{sup 2}. The dominant landslide types are retrogressive thaw flows and active layer detachments, followed by rock falls, debris flows, earth slides, surficial landslides, and retrogressive thaw slides. Nearly half of all landslides took place in morainal deposits, 19 per cent in lacustrine sediments, 14 per cent in bedrock, and 13 per cent in glaciofluvial sediments. According to tone, texture, and vegetation regrowth attributes, 39 per cent of the landslides were classified as being older than 50 years, 39 per cent were 10 to 50 years old and 22 per cent were less than 10 years old.

  12. Seismic modeling of multidimensional heterogeneity scales of Mallik gas hydrate reservoirs, Northwest Territories of Canada

    In hydrate-bearing sediments, the velocity and attenuation of compressional and shear waves depend primarily on the spatial distribution of hydrates in the pore space of the subsurface lithologies. Recent characterizations of gas hydrate accumulations based on seismic velocity and attenuation generally assume homogeneous sedimentary layers and neglect effects from large- and small-scale heterogeneities of hydrate-bearing sediments. We present an algorithm, based on stochastic medium theory, to construct heterogeneous multivariable models that mimic heterogeneities of hydrate-bearing sediments at the level of detail provided by borehole logging data. Using this algorithm, we model some key petrophysical properties of gas hydrates within heterogeneous sediments near the Mallik well site, Northwest Territories, Canada. The modeled density, and P and S wave velocities used in combination with a modified Biot-Gassmann theory provide a first-order estimate of the in situ volume of gas hydrate near the Mallik 5L-38 borehole. Our results suggest a range of 528 to 768 × 106 m3/km2 of natural gas trapped within hydrates, nearly an order of magnitude lower than earlier estimates which did not include effects of small-scale heterogeneities. Further, the petrophysical models are combined with a 3-D finite difference modeling algorithm to study seismic attenuation due to scattering and leaky mode propagation. Simulations of a near-offset vertical seismic profile and cross-borehole numerical surveys demonstrate that attenuation of seismic energy may not be directly related to the intrinsic attenuation of hydrate-bearing sediments but, instead, may be largely attributed to scattering from small-scale heterogeneities and highly attenuate leaky mode propagation of seismic waves through larger-scale heterogeneities in sediments.

    Full Text Available Sensitivity to anthropogenic disturbance in conjunction with slow population recovery has raised conservation concerns over impacts to raptor species from industrial development in pristine areas of their North American breeding range. We evaluated whether the presence of two diamond mines resulted in negative effects to nest use and hatch success of breeding falcons in the southern Arctic barren-grounds of the Northwest Territories. A total of 20 nest sites of Peregrine Falcon (Falco peregrinus and Gyrfalcon (Falco rusticolus breeding within 26 km of the Diavik and Ekati diamond mines were monitored annually during 1998 to 2010. The objective of the study was to test the effects of distance from mines, relative nest age, rainfall, small mammal abundance, and mine activity levels on nest occupancy and hatch rates. Model selection results indicated that nests that were older were more likely and consistently used than nests that were established more recently. A decrease in nest use associated with the mines was not detected. Hatch success was best explained by a positive association with distance from development and a negative trend over the study period, however, these effects were weak. Hatch success of nests within and beyond an estimated 5.9 km distance threshold was similar, and for nest sites within this distance was unrelated to annual changes in accumulated mine footprint area through time. Hatch success for nest sites near Diavik was unrelated to changes in this mine's activity through time. Although natural and anthropogenic effects were generally weak, the lines of evidence suggested that the observed patterns were more likely the result of natural factors operating at a regional scale than more localized effects from the activity of two diamond mines.

    Full Text Available Abstract Objective The prevalence of smoking in Aboriginal Canadians is higher than non-Aboriginal Canadians, a behavior that also tends to alter dietary patterns. Compared with the general Canadian population, maternal smoking rates are almost twice as high. The aim of this study was to compare dietary adequacy of Inuvialuit women of childbearing age comparing smokers versus non-smokers. Research methods & procedures A cross-sectional study, where participants completed a culturally specific quantitative food frequency questionnaire. Non-parametric analysis was used to compare mean nutrient intake, dietary inadequacy and differences in nutrient density among smokers and non-smokers. Multiple logistic regression analyses were performed for key nutrients inadequacy and smoking status. Data was collected from three communities in the Beaufort Delta region of the Northwest Territories, Canada from randomly selected Inuvialuit women of childbearing age (19-44 years. Results Of 92 participants, 75% reported being smokers. There were no significant differences in age, BMI, marital status, education, number of people in household working and/or number of self employed, and physical activity between smokers and non-smokers. Non-parametric analysis showed no differences in nutrient intake between smokers and non-smokers. Logistic regression however revealed there was a positive association between smoking and inadequacies of vitamin C (OR = 2.91, 95% CI, 1.17-5.25, iron (OR = 3.16, 95% CI, 1.27-5.90, and zinc (OR = 2.78, 95% CI, 1.12-4.94. A high percentage of women (>60%, regardless of smoking status, did not meet the dietary recommendations for fiber, vitamin D, E and potassium. Conclusions This study provides evidence of inadequate dietary intake among Inuvialuit of childbearing age regardless of smoking behavior.

    The northern extent of Canada's northern boreal forest is largely inaccessible resulting in logistical, financial, and human challenges with respect to obtaining concise and accurate forest resource inventory (FRI) attributes such as stand height, aboveground biomass and forest carbon stocks. This challenge is further exacerbated by mandated government resource management and reporting of key attributes with respect to assessing impacts of natural disturbances, monitoring wildlife habitat and establishing policies to mitigate effects of climate change. This study presents a framework methodology utilized to inventory canopy height and crown closure over a 420,000 km2 area in Canada's Northwest Territories (NWT) by integrating field, LiDAR and satellite remote sensing data. Attributes are propagated from available field to coincident airborne LiDAR thru to satellite laser altimetry footprints. A quality controlled form of the latter are then submitted to a k-nearest neighbor (kNN) imputation algorithm to produce a continuous map of each attribute on a 30 m grid. The resultant kNN stand height (r=0.62, p=0.00) and crown closure (r=0.64, p=0.00) products were identified as statistically similar to a comprehensive independent airborne LiDAR source. Regional uncertainty can be produced with each attribute to identify areas of potential improvement through future strategic data acquisitions or the fine tuning of model parameters. This study's framework concept was developed to inform Natural Resources Canada - Canadian Forest Service's Multisource Vegetation Inventory and update vast regions of Canada's northern forest inventories, however, its applicability can be generalized to any environment. Not only can such a framework approach incorporate other data sources (such as Synthetic Aperture Radar) to potentially better characterize forest attributes, but it can also utilize future Earth observation mission data (for example ICESat-2) to monitor forest dynamics and the

    A study examining opportunities and barriers for wind energy development in 4 communities in the Northwest Territories was presented. A review of previous studies examining the feasibility of wind energy in this region was also provided, as well as technical and socio-economic analyses on the displacement of diesel fuels by wind energy. Details of site visits and public meetings to discuss energy concerns were included. Four key locations for installing wind monitoring stations were determined. Interconnection issues and opportunities for wind energy into the local power grids were discussed. Geographic features of the various communities, as well as energy consumption details and wind climates were described. It was noted that there are special considerations for wind turbines in the North, and issues concerning icing and anti-icing technologies were examined. It was suggested that medium-scale wind turbines were the most appropriate size for the Inuvialuit region, due to low costs and ease of installation and redundancy. RETScreen software was used to develop an economic overview of the opportunities for wind energy systems in the 4 communities. Historical wind speed data collected at airports by Environment Canada was used in this analysis. Low and high penetration systems were evaluated. Results of the analysis indicated that wind generated electricity does not appear to be economically viable when compared solely to the displaced cost of diesel fuel. However, environmental factors make it a viable technology. It was concluded that there is potential for wind energy developments in the region, provided that sites are carefully selected. Cost estimates for the proposed wind-monitoring program were also included. 13 tabs., 15 figs

  17. CO2 dynamics of tundra ponds in the low-Arctic, Northwest Territories, Canada

    Buell, Mary-Claire

    Extensive research has gone into measuring changes to the carbon storage capacity of Arctic terrestrial environments as well as large water bodies in order to determine a carbon budget for many regions across the Arctic. Inland Arctic waters such as small lakes and ponds are often excluded from these carbon budgets, however a handful of studies have demonstrated that they can often be significant sources of carbon to the atmosphere. This study investigated the CO2 cycling of tundra ponds in the Daring Lake area, Northwest Territories, Canada (64°52'N, 111°35'W), to determine the role ponds have in the local carbon cycle. Floating chambers, nondispersive infrared (NDIR) sensors and headspace samples were used to estimate carbon fluxes from four selected local ponds. Multiple environmental, chemical and meteorological parameters were also monitored for the duration of the study, which took place during the snow free season of 2013. Average CO2 emissions for the two-month growing season ranged from approximately -0.0035 g CO2-C m-2 d -1 to 0.12 g CO2-C m-2 d-1. The losses of CO2 from the water bodies in the Daring Lake area were approximately 2-7% of the CO2 uptake over vegetated terrestrial tundra during the same two-month period. Results from this study indicated that the production of CO2 in tundra ponds was positively influenced by both increases in air temperature, and the delivery of carbon from their catchments. The relationship found between temperature and carbon emissions suggests that warming Arctic temperatures have the potential to increase carbon emissions from ponds in the future. The findings in this study did not include ebullition gas emissions nor plant mediated transport, therefore these findings are likely underestimates of the total carbon emissions from water bodies in the Daring Lake area. This study emphasizes the need for more research on inland waters in order to improve our understanding of the total impact these waters may have on the

    The Canadian government must decide how to manage the development of oil and gas resources in the Northwest Territories (NT). This paper outlined a scenario that will allow oil and gas companies to earn fair returns on their investments while providing maximum benefits for resource owners. Canada's federal government will need to review and reform royalty rates as well as the bidding process for awarding oil and gas leases. The NT government must allow obtain revenues for oil and gas resource owners in the territory. A portion of the revenues must be invested in long-term funds to be shared with future generations in order to mitigate the impact of resource development and provide a store of wealth while also diversifying and strengthening the local economy. A review of the territory's resource royalty and taxation system is needed before the Mackenzie gas project takes place. An outline of the territory's resource revenue collection process was provided, as well as a set of revised tax and royalty options. 5 tabs., 5 figs.

    2006-02-01

    This paper provided a high-level overview of research related to the boom and bust cycle of resource-based economic development and community infrastructure in the north, particularly in the Northwest Territories. The paper focused on what is known and on knowledge gaps that needed to be filled in each of 3 theme areas for an experts workshop on northern communities. The themes that were discussed at the workshop and in this paper were: the connections between non-renewable resources development and community infrastructure in the north; planning for resource development; and strategies for moving ahead and putting ideas into practice. The paper discussed the objectives of the research and discussed findings under each of the 3 themes. Topics discussed included: changes in the infrastructure mix; infrastructure and climate change; infrastructure financing; uncertainty; knowledge; planning tools; stakeholder participation; and measuring and monitoring planning implementation. Data availability was also discussed along with funding mechanisms, technological innovations and community capacity building. It was concluded that strategies for dealing with the boom-induced infrastructure challenges facing communities in the Northwest Territories should focus on making more creative use of available funding; promoting technical innovation; and improving maintenance capacity at the community level. 62 refs

    Traditional foods have significant nutritional, sociocultural and economic value in subarctic First Nations communities of the Northwest Territories, and play a crucial role in promoting cultural continuity and sovereignty. Omega-3 polyunsaturated fatty acids (N-3 PUFAs), including eicosapentaenoic (EPA) and docosahexaenoic acid (DHA), carry significant benefits for neurocognitive development and cardiovascular health. However, the health risks posed by methylmercury may serve to undermine the benefits of fish consumption in Northern Indigenous communities. The objective of this study was to characterize profiles for mercury (Hg) and fatty acids in fish species harvested across lakes of the Dehcho Region, in the Mackenzie Valley of the Northwest Territories, to better understand the risks and benefits associated with traditional foods. Hg levels increased with trophic position, with the highest levels found in Burbot, Lake Trout, Walleye, and Northern Pike. Lake Trout, along with planktivorous species including Lake Whitefish, Cisco, and Sucker, demonstrated higher N-3 PUFAs than other species. Negative associations were observed between Hg and N-3 PUFAs in Lake Trout, Northern Pike, Walleye and Burbot. Further stratifying these relationships revealed significant interactions by lake. Significant differences observed in fatty acid and Hg profiles across lakes underscore the importance of considering both species- and lake-specific findings. This growing dataset of freshwater fish of the Dehcho will inform future efforts to characterize human Hg exposure profiles using probabilistic dose reconstruction models.

  4. delta 18O variations in snow on the Devon Island ice cap, Northwest Territories, Canada

    1979-01-01

    A study of delta 18 O variations of snow samples taken on traverses across the Devon Island ice cap in June 1971, 1972, and 1973 has shown a difference between the accumulation conditions on the souteast and nortwest sides of the ice cap. On the souteast side there is an increasing depletion of 18 O in the snow with increasing elevation. This pattern is attibuted to the effect of orographic uplift of air masses moving over the ice cap from the southeast, which promotes condensation and precipitation due to adiabatic cooling. On the northwest side of the ice cap there is no evidence of any further depletion of 18 O in snow, neither with increasing distance from the possible moisture source in Baffin Bay to the southeast nor with increasing elevation if the air mass comes from the northwest. In this case condensation is due to isobaric cooling so that precipitation is generally from level cloud bases. The changes inferred for the isotopic composition of the water vapour as it rises up the southeast slope are found to be consistent with its depletion through precipitation under near-equilibrium conditions. It is calculated that approximately 30% of the moisture at sea level on the southeast side of the ice cap and 8% at the top of the ice cap are of local origin. Lower temporal and aerial variability of the delta values on the southeast side of the ice cap is attributed to dominance of the Baffin Bay low on that side Effecting consistency of storm conditions there. The delta values of ice in the ablation zone on the Sverdrup Glacier show the combined effect of ice movement from the accumulation to the ablation zone and climatic change during the period of movement from cold to warm and back to cold conditions again.

    Full Text Available The dynamic of using the rivers energy from Republic of Moldova territory. One of the least explored and tapped energy sources in Moldova are the inland rivers. Considering the critical condition of the country regarding energy sources, it would be highly necessary to study the feasibility of hydraulic energy reserves. Although Moldova has no major rivers with a large flow of water, the network of small tributaries of its two large rivers, Dniester and Prut, could be used to a certain extent for partial power supply to villages situated along inland watercourses.The first scientific developments concerning the hydropower potential of the rivers in Bessarabia belong to professor D. Pavel. Around 1933 he was suggesting a series of hydro-technical facilities on Prut and Dniester rivers and their tributaries. Subsequently, in the ‘40s of the 20th century the first power plants were built on small rivers. After World War II some small hydropower plants, built during the interwar period, had been restored and some other put into operation. These include the plant at Dubăsari with a capacity of 48 MW that started operating in 1954 on Dniester River, and the hydroelectric complex at Costeşti -Stânca with a capacity of 16 MW, in 1978 on the River Prut. Nevertheless, the leverage of hydroelectric resources is not significant, only 23 being used nowadays, which is 7% of the hydropower potential - a rather modest number compared to other states.

    2009-03-15

    The Sandy Lake Fire 13 of July 2008 was an intense forest fire that burned up to and across a power line right-of-way in the Northwest Territories, approximately 160 km northwest of Fort Smith. The terrain in the area is flat and vegetation is characterized by boreal pine and black spruce uplands with black spruce and tamarack in lower areas and adjacent to wetlands. This report documented post fire conditions at locations where the fire crossed the power line. The towers on this line were made from an aluminum alloy and may not have had the same resistance to heat damage as steel towers, more commonly used on major transmission lines. The transmission line was de-energized during the fire. Therefore, the effects of fire on power transmission were not documented. Although the intense wildfire crossed sections of the power line, it did not result in observable damage to the towers or lines. Fire intensity was likely greater than 40,000 kw/m along some sections of the right-of-way. Although the management of the right-of-way may have reduced heat exposure to the transmission towers, it did not stop the fire. Pine mixed with an aspen component greater than 50 per cent had a mitigating effect on fire behaviour. The fire did not result in any immediate damage to the power line infrastructure. It was concluded that the use of power lines for fire operations should consider right-of-way width in order to assess equipment maneuverability, especially around tower guy wires. 5 refs., 1 tab., 12 figs.

    Full Text Available Northwest Mexico’s irrigation landscape, known today as El Distrito de Riego 038, or El Valle del Mayo, issues from historical struggles to build an official order out of a diverse world of signs, symbols, processes, places, and peoples. It is the ancestral home of the Yoreme (Mayo, an indigenous group for whom colonisation and agricultural development have meant the loss of autonomy and of the seasonal mobility required to subsist in an arid land. It is also the birthplace of President Álvaro Obregón, a one-time chickpea farmer who transformed late-19th century irrigation praxis into the laws and institutions of 20th century water management. Reshaping territory for the ends of centralising ('federalising' water resources has always proved exceedingly difficult in the Mayo. But this was particularly so in the beginning of the federalisation process, a time of aggressive modernisation under the direction of President Porfirio Díaz (1876-1910. Research on Mexican hydraulic politics and policy, with some important exceptions, has tended to focus on the scale and scope of centralisation. Scholars have paid less attention to the moments and places where water escapes officials’ otherwise ironclad grasp. This paper explores water governance (and state formation more broadly in the late 19th century, on the eve of Mexico’s 1910 Revolution, as an ongoing, ever-inchoate series of territorial claims and projects. Understanding the weaknesses and incompleteness of such projects offers critical insight into post-revolutionary and/or contemporary hydraulic politics.

    McKinley Bay is a shallow protected bay along the eastern Beaufort Sea coast which provides an important habitat for diving ducks. Since 1979, the bay has been the site of a winter harbor and support base for oil and gas exploraton in the Beaufort Sea. Aerial surveys for bird abundance and distribution were conducted in August 1991 as a continuation of long-term monitoring of birds in McKinley Bay and Hutchison Bay, a nearby area used as a control. The main objectives of the 1991 surveys were to expand the set of baseline data on natural annual fluctuations in diving duck numbers, and to determine if numbers of diving ducks had changed since the initial 1981-85 surveys. On the day with the best survey conditions, the population of diving ducks at McKinley bay was estimated at ca 32,000, significantly more than 1981-85. At Hutchison Bay, there were an estimated 11,000 ducks. As in previous years, large numbers of diving ducks were observed off Atkinson Point at the northwest corner of McKinley Bay, at the south end of the bay, and in the northeast corner near a long spit. Most divers in Hutchison Bay were at the west side. Diving ducks, primarily Oldsquaw and scoter, were the most abundant bird group in the study area. Observed distribution patterns of birds are discussed with reference to habitat preferences. 16 refs., 7 figs., 30 tabs.

    The Edaiila study area of interest is located in the Deline District of the Sahtu Settlement area in the Northwest Territories. It lies in the Proterozoic Bear geologic province of the Canadian Shield. The area is currently covered by prospecting claims and is likely undergoing exploration for uranium, precious metals, base metals and diamonds. This document presented a Phase 1 non-renewable resource assessment (NRA) of the area that was completed as part of the Northwest Territories Protect Area Strategy (PAS). It presented compiled historical information, provided a preliminary resource assessment and made recommendations for further Phase 2 studies. This region is within the continuous permafrost zone and is characterized by a high subarctic climate. The study area straddles the tree line and contains vegetation typical of taiga and tundra regions. The bedrock covering the flat to gently rolling topography is covered by undulating glacial drift, raised beaches and outwash deposits. About 25 per cent of the area is covered by wetlands. The Bear province is subdivided into two major domains, the Wopmay orogen and the Coppermine homocline. In the eastern portion of the study area, basement rocks are part of the Great Bear magmatic zone and are locally exposed in the Fault River area. Although basement rocks in the western portion of the study area are not exposed, they are assumed to be composed of the Hottah terrane. 86 refs., 14 tabs., 7 figs., 4 appendices.

    In the northern territories of Canada the government requirement to provide local benefits to residents has been adopted and enshrined in land claims settlements, and consideration of the benefits that can be provided to First Nations when oil and gas exploration and development occurs on or near aboriginal land is mandatory. Access to their lands will depend on more than fair levels of rent or compensation for damages to the land itself. It also depends on the wider benefits that the project can offer to the whole community. Provision for the negotiation of benefits agreements ought be built into the planning for oil and gas projects in the north, and, as a result, the early establishment of a positive relationship with local communities is necessary. Even though the law mandates that there be a negotiation of a benefits agreement, the process is bilateral and the outcome rests within the control of the two parties. An early agreement on benefits issues is seen positively by the government in the overall legal context. The new legal regimes affecting oil and gas operations have provided First Nations with settled land claims with greater confidence about the part they can play in the development process, and joint ventures are being formed between oil and gas companies and aboriginal communities to cooperate in oil and gas activities. These new relationships are only in the development stage, and, as experiences accumulates, First Nations will understand better what level of benefits are reasonable and possible from oil and gas exploration and development

    A study was carried out to identify and evaluate alternative waste treatment and/or disposal technologies that would be effective in improving the management of slops, used glycol and industrial solid wastes at Nalluk Base, Tuktoyaktuk, Northwest Territories. This site was used as a base for an offshore oil and gas drilling program between 1983 and 1992. Background research was conducted to review the biophysical, regulatory and socioeconomic conditions which have had an influence on Nalluk Base waste management operations. Concerns in relation to management of industrial wastes at the base include: extreme climate, permafrost geology, remote location, excessive government regulations but no specific legislation, and distrust of white man by local Inuvialuit. The five major waste streams handled at the base (used glycol, oily slops, scrap metal, used containers and ash) were characterized in terms of physical and chemical characteristics, anticipated volumes, and potential contaminants. Eighty-six waste treatment and disposal processes were reviewed for their applicability in treating each of the five waste streams. Short-listed options were subjected to full-cost environmental accounting. Preferred options identified were: used glycol, one site reuse using vacuum distillation; unseparated slops and used oil/fuel, off-site cement kiln incineration; oily wastewater, on-site evaporation; sludge, offsite landfill; scrap metal and used containers, Hamlet landfill (current practise); and ash, off-site landfill. 178 refs., 15 figs., 34 tabs.

    This report examines baseline concentrations and transfer of the uranium decay products polonium-210 and lead-210 in the lichen-caribou-wolf food chain at two locations in the Northwest Territories, Baker Lake and Snowdrift. At each location, concentrations of the two radionuclides were determined in the lichen species Cetraria nivalis and Cladina mitis, and several tissues from caribou and wolves. Baseline concentrations and transfer coefficients within the food chain were compared between the two locations. Lichen samples were also collected from Kasba Lake, a third hunting ground used by northern Saskatchewan hunters. The lichen species chosen were common forage for caribou. Both the predominant lichen species at each location and rumen contents were used to estimate the winter diet of caribou in the calculation of transfer coefficients. The results are relevant to environmental monitoring in areas of potential future uranium mining development and the transfer coefficients determined in the study may be used to estimate radionuclide concentrations and radiation doses in future environmental assessments

    1982-01-01

    The oldest uranium mineralisation found in the Great Bear batholith during this study may be hydrothermal pitchblende-hematite veins at Hottah Lake. Their apparent age of 2058 +- 34 Ma can also be explained by the contamination of deposits only 440 +- 57 Ma old, which is the age of pitchblende veins nearby. Numerous pendants of metamorphosed, uraninite-bearing 'black sand' placers in a north-trending belt west of the Wopmay Fault are 1860 +- 20 Ma old, the age of the granites that intrude them. Mineralisation at Echo Bay is from 1500 +- 10 to 1424 +- 29 Ma old, and extends up to 30 km north and 40 km south of Echo Bay. The JD claims contain small quartz vein deposits dated at 535 +- 164 and 1092 +- 115 Ma. At Mountain Lake, pitchblende in Helikian sandstones overlying the batholith is 1076 +- 96 Ma old. Polymetallic veinlets at Mazenod Lake are 457 +- 26 Ma old. Pitchblende in a giant quartz vein at the Rayrock mine is 511 +- 86 Ma old. Small pitchblende veins east of the batholith along the Coppermine River are between 400 and 660 Ma old. All the deposits are either between approximately 395 and 660 Ma old, or indicate remobilization during this interval. These events may be related to a marine transgression and regression approximately 600 and 350 Ma ago, respectively

    Together with its partners, the Northern Climate ExChange (NCE, part of the Yukon Research Centre at Yukon College) has been mapping permafrost-related hazard risk in northern communities since 2010. By integrating geoscience and climate project data, we have developed a series of community-scale hazard risk maps. The maps depict hazard risk in stoplight colours for easy interpretation, and support community-based, future-focused adaptation planning. Communities, First Nations, consultants and local regulatory agencies have used the hazard risk maps to site small-scale infrastructure projects, guide land planning processes, and assess suitability of land development applications. However, we know that assessing risk is only one step in integrating the implications of permafrost degradation in societal responses to environmental change. To build on our permafrost hazard risk maps, we are integrating economic principles and traditional land use elements. To assess economic implications of adaptation to permafrost change, we are working with geotechnical engineers to identify adaptation options (e.g., modified building techniques, permafrost thaw mitigation approaches) that suit the risks captured by our existing hazard risk maps. We layer this with an economic analysis of the costs associated with identified adaptation options, providing end-users with a more comprehensive basis upon which to make decisions related to infrastructure. NCE researchers have also integrated traditional land use activities in assessments of permafrost thaw risk, in a project led by Jean Marie River First Nation in the Northwest Territories. Here, the implications of permafrost degradation on food security and land use priorities were assessed by layering key game and gathering areas on permafrost thaw vulnerability maps. Results indicated that close to one quarter of big and small game habitats, and close to twenty percent of key furbearer and gathering areas within the First Nation

    Full Text Available From the last decades of the twentieth century, the rural sector of the Argentine Northwest was the scene of deep territorial and productive transformations linked to the expansion of extractive activities. The effects of these activities include privatization, concentration and land grabs, generating an increase of social and territorial inequality. The aim of this paper is therefore to analyze the socio-territorial inequality in rural areas of Northwest Argentina in the first decade of the XXI century. Four dimensions were analyzed: poverty, education, habitat quality, and agrarian structure. For the analysis of the first three dimensions, data from national population census 2001 and 2010 were used. For the analysis of the territorial and productive transformations were used data from national agricultural censuses 1988, 2002 and 2008. The results allow us to observe that while the habitat quality and education improved during the first decade of the century, there are high poverty and vulnerability in a context of a progressively unequal agrarian structure.

    Environmental tracers (such as major ions, stable and radiogenic isotopes, and heat) monitored in natural waters provide valuable information for understanding the processes of river-groundwater interactions in arid areas. An integrated framework is presented for interpreting multi-tracer data (major ions, stable isotopes (2H, 18O), the radioactive isotope 222Rn, and heat) for delineating the river-groundwater interactions in Nalenggele River basin, northwest China. Qualitative and quantitative analyses were undertaken to estimate the bidirectional water exchange associated with small-scale interactions between groundwater and surface water. Along the river stretch, groundwater and river water exchange readily. From the high mountain zone to the alluvial fan, groundwater discharge to the river is detected by tracer methods and end-member mixing models, but the river has also been identified as a losing river using discharge measurements, i.e. discharge is bidirectional. On the delta-front of the alluvial fan and in the alluvial plain, in the downstream area, the characteristics of total dissolved solids values, 222Rn concentrations and δ18O values in the surface water, and patterns derived from a heat-tracing method, indicate that groundwater discharges into the river. With the environmental tracers, the processes of river-groundwater interaction have been identified in detail for better understanding of overall hydrogeological processes and of the impacts on water allocation policies.

  18. Effects of Attenuation of Gas Hydrate-bearing Sediments on Seismic Data: Example from Mallik, Northwest Territories, Canada

    Wave attenuation is an important physical property of hydrate-bearing sediments that is rarely taken into account in site characterization with seismic data. We present a field example showing improved images of hydrate- bearing sediments on seismic data after compensation of attenuation effects. Compressional quality factors (Q) are estimated from zero-offset Vertical Seismic Profiling data acquired at Mallik, Northwest Territories, Canada. During the last 10 years, two internationally-partnered research drilling programs have intersected three major intervals of sub-permafrost gas hydrates at Mallik, and have successfully extracted core samples containing significant amount of gas hydrates. Individual gas hydrate intervals are up to 40m in thickness and are characterized by high in situ gas hydrate saturation, sometimes exceeding 80% of pore volume of unconsolidated clastic sediments having average porosities ranging from 25% to 40%. The Q-factors obtained from the VSP data demonstrate significant wave attenuation for permafrost and hydrate- bearing sediments. These results are in agreement with previous attenuation estimates from sonic logs and crosshole data at different frequency intervals. The Q-factors obtained from VSP data were used to compensate attenuation effects on surface 3D seismic data acquired over the Mallik gas hydrate research wells. Intervals of gas hydrate on surface seismic data are characterized by strong reflectivity and effects from attenuation are not perceptible from a simple visual inspection of the data. However, the application of an inverse Q-filter increases the resolution of the data and improves correlation with log data, particularly for the shallowest gas hydrate interval. Compensation of the attenuation effects of the permafrost likely explains most of the improvements for the shallow gas hydrate zone. Our results show that characterization of the Mallik gas hydrates with seismic data not corrected for attenuation would tend to

    Previous studies highlight a possible association between alcohol-drinking patterns and dietary inadequacies, which may have negative implications, particularly for women of child-bearing age. The present study aimed to compare dietary adequacy among alcohol drinkers versus nondrinkers in Inuvialuit women of child-bearing age. A cross-sectional survey of 92 randomly selected women of childbearing age (19-44 years) was conducted in three communities in the Northwest Territories of Arctic Canada, using a validated quantitative food frequency questionnaire. Data were analysed to compare mean daily energy and nutrient intakes, dietary adequacy and nutrient densities (per 4184 kJ) between alcohol drinkers and nondrinkers, as well as heavy drinkers and nonheavy drinkers, using the nonparametric Wilcoxen rank sum test. The response rate was between 65% and 85% depending on the community sampled. Of the study participants, 54% (n = 49) were drinkers and 46% (n = 42) were nondrinkers. Of the drinkers, 45% (n = 22) were heavy drinkers. Mean energy intakes were high among all women, although they were significantly higher among drinkers [17,179 kJ (4106 kcal)] compared to nondrinkers [13,317 kJ (3183 kcal)]. There were no significant differences in nutrient intake between the two groups; however, drinkers had a lower nutrient density for most nutrients. Heavy drinkers had a significantly lower nutrient density for all nutrients, except protein, iron, and vitamins B6 , C and D, compared to nonheavy drinkers. The findings of the present study provide evidence of inadequate dietary intake among Inuvialuit of child-bearing age, regardless of alcohol-drinking behaviour. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    Managing surface water and groundwater as a unified system is important for water resource exploitation and aquatic ecosystem conservation. The unified approach to water management needs accurate characterization of surface water and groundwater interactions. Temperature is a natural tracer for identifying surface water and groundwater interactions, and the use of remote sensing techniques facilitates basin-scale temperature measurement. This study focuses on the Heihe River basin, the second largest inland river basin in the arid and semi-arid northwest of China where surface water and groundwater undergoes dynamic exchanges. The spatially continuous river-surface temperature of the midstream section of the Heihe River was obtained by using an airborne pushbroom hyperspectral thermal sensor system. By using the hot spot analysis toolkit in the ArcGIS software, abnormally cold water zones were identified as indicators of the spatial pattern of groundwater discharge to the river.

    Full Text Available Waste disposal and treatment problem consideration in the Republic of Serbia is making a pioneer steps. Main goal of this paper is to emphasize problems of waste disposal on waterways in urban areas, which consists of three aspects: uncontrolled disposal, possibilities of waste elimination and institutional model of collecting and recycling. Considering the fact that Draft version of Waste disposal law is not yet adopted by the national government (beside the fact that it contains the question of disposing and recycling municipal solid waste and that it is not elaborating the problem of dumping the municipal waste into rivers, this paper will give methodological and legislative recommendations for the solution of this problem. However, city of Belgrade and the other cities in Serbia are often facing serious problems (arranged riverfronts covered with municipal waste. Because of that, it is necessary to define methods of collecting and treatment of waste disposed in the water streams (in the area of technology. It is also important to determine legislative framework, and also to establish hierarchy in decision-making on the local level. One of the main goals is to determine new aspects of public communal utilities (so called "river communal utility", which will have jurisdiction in this area. International experiences must be analyzed separately and based on them is proposed new concept of elimination of waste from the rivers. Implementation of this pilot project is recommended on the river Danube and the river Sava on the territory of the city of Belgrade.

    Elevated levels of arsenic (As) and antimony (Sb) in water and sediments are legacy residues found downstream from gold-mining activities at the Giant Mine in Yellowknife, Northwest Territories (NWT), Canada. To track the transport and fate of As and Sb, samples of mine-waste from the mill, and surface water, sediment, pore-water, and vegetation downstream of the mine were collected. Mine waste, pore-water, and sediment samples were analyzed for bulk chemistry, and aqueous and solid-state speciation. Sediment and vegetation chemistry were evaluated using scanning electron microscope imaging, synchrotron-based element mapping and electron microprobe analysis. The distributions of As and Sb in sediments were similar, yet their distributions in the corresponding pore-waters were mostly dissimilar, and the mobility of As was greater than that of Sb. Competition for sorption sites is the most likely cause of elevated Sb concentrations in relatively oxidized pore-water and surface water. The aqueous and solid-state speciation of As and Sb also differed. In pore-water, As(V) dominated in oxidizing environments and As(III) in reducing environments. In contrast, the Sb(V) species dominated in all but one pore-water sample, even under reducing conditions. Antimony(III) appears to preferentially precipitate or adsorb onto sulfides as evidenced by the prevalence of an Sb(III)-S secondary solid-phase and the lack of Sb(III)(aq) in the deeper zones. The As(V)–O solid phase became depleted with depth below the sediment–water interface, and the Sb(V)–O phase persisted under relatively reducing conditions. In the surficial zone at a site populated by Equisetum fluviatile (common horsetail), As and Sb were associated with organic material and appeared mobile in the root zone. In the zone below active plant growth, As and Sb were associated primarily with inorganic phases suggesting a release and reprecipitation of these elements upon plant death.

    Full Text Available Mapping of surficial geology is an important requirement for broadening the geoscience database of northern Canada. Surficial geology maps are an integral data source for mineral and energy exploration. Moreover, they provide information such as the location of gravels and sands, which are important for infrastructure development. Currently, surficial geology maps are produced through expert interpretation of aerial photography and field data. However, interpretation is known to be subjective, labour-intensive and difficult to repeat. The expert knowledge required for interpretation can be challenging to maintain and transfer. In this research, we seek to assess the potential of deep neural networks to aid surficial geology mapping by providing an objective surficial materials initial layer that experts can modify to speed map development and improve consistency between mapped areas. Such an approach may also harness expert knowledge in a way that is transferable to unmapped areas. For this purpose, we assess the ability of convolution neural networks (CNN to predict surficial geology classes under two sampling scenarios. In the first scenario, a CNN uses samples collected over the area to be mapped. In the second, a CNN trained over one area is then applied to locations where the available samples were not used in training the network. The latter case is important, as a collection of in situ training data can be costly. The evaluation of the CNN was carried out using aerial photos, Landsat reflectance, and high-resolution digital elevation data over five areas within the South Rae geological region of Northwest Territories, Canada. The results are encouraging, with the CNN generating average accuracy of 76% when locally trained. For independent test areas (i.e., trained over one area and applied over other, accuracy dropped to 59–70% depending on the classes selected for mapping. In the South Rae region, significant confusion was found

    Full Text Available Abstract In the Tapajos-Xingu interfluve, one of the largest birds of prey, the Harpy Eagle, is under intense anthropogenic pressure due to historical and recent reductions in forest cover. We studied prey availability and use by Harpy Eagle on six breeding territories on the low- and mid-Xingu River, between 2013 and 2015. We evaluated food resource availability using the environmental-surveys database from two methods: terrestrial surveys (RAPELD method and fauna rescue/flushing before vegetation suppression for the Belo Monte Hydroelectric Complex construction. Harpy Eagle diet was identified by prey remains sampled around six nest trees. Eighteen species of mammals, birds and reptiles comprised the prey items. Most prey species were sloths, primates and porcupines, which have arboreal habits and are found in forested areas, but two species, hoatzin and iguana, are usually associated with riverine habitats. The proportion of prey from each species predated on the nest best studied was different from estimated availability (χ2 = 54.23; df = 16; p < 0.001, however there was a positive correlation (rs = 0.7; p < 0.01 between prey species consumed and abundance available, where the predation was more on species more abundant. Continuous monitoring of the Harpy Eagle diet at these nests could evidence changes in the assemblage of prey species available for Harpy Eagles, due to changes in the seasonal flood pulse of the Xingu River to be caused by the operation of the hydroelectric dam, and changes in habitat features by forest reduction around breeding territories. We believe that it is important to consider the protection of remnants of forested areas in the landscape matrix surrounding the breeding territories to maintain the food resource availability and allow all pairs to successfully reproduce.

    Full Text Available Abstract. Aim. The aim of this work was to study the content of poisonous substances in the aquatic environment of the river Terek during the year of 2016 in the territory of the Chechen Republic. Materials and methods. Water samples of the river Terek were analyzed in the Laboratory of Environmental Control of the Ministry of Natural Resources and Environmental Protection. Dry residue was determined by weight analysis; stiffness by acid-base titration; acid-base properties by potentiometric method; the ion content was determined spectrophotometrically; concentration of heavy metals was identified with voltammetric analyzer; concentration of calcium and magnesium ions was measured titrometrically with Trilon B in the presence of an appropriate indicator. Results. The intensity of contamination of the water body was assessed according to the following parameters: total hardness, dry residue, permanganate value, pH, chlorides, dissolved oxygen, sulfates, nitrates and heavy metals content. In the course of the study, sensory characteristics such as smell, taste, turbidity and color were also determined; indicator value - permanganate value, which characterizes the contamination of water bodies with industrial and household wastewater as well as atmospheric precipitation. Conclusion. Studies of the ecological state of Terek, the main river of the Chechen Republic, have shown that the quality of the water body corresponds to hygienic standards: the content of pollutants is much lower than the maximum permissible concentration. In terms of water quality, the Terek River belongs to the 2nd class of surface water bodies, the water quality characteristic is relatively clean and the river pollution index corresponds to II.

    Information about morphometric characteristics of relief is necessary for researches devoted to geographic characteristics of territory, its zoning, assessment of erosion processes, geoecological condition and others. For the Volga Federal District for the first time a spatial database of geomorphometric parameters 1: 200 000 scale was created, based on a river basin approach. Watersheds are used as a spatial units created by semi-automated method using the terrain and hydrological modeling techniques implemented in the TAS GIS and WhiteBox GIS. As input data DEMs SRTM and Aster GDEM and hydrographic network vectorized from topographic maps were used. Using DEM highlighted above for each river basin, basic morphometric relief characteristics such as mean height, slope steepness, slope length, height range, river network density and factor LS were calculated. Basins belonging to the geomorphological regions and landscape zones was determined, according to the map of geomorphological zoning and landscape map. Analysis of variance revealed a statistically significant relationship between these characteristics and geomorphological regions and landscape zones. Consequently, spatial trends of changes of analyzed morphometric characteristics were revealed.

    Currently, the Federal government coordinates the planning and operation of the Federal Columbia River Power System (FCRPS) with projects owned and operated by the region's non-Federal hydrogenerating utilities pursuant to the Pacific North-west Coordination Agreement (PNCA). The Bureau of Reclamation (Reclamation), the Corps of Engineers (Corps), and the Bonneville Power Administration (BPA) are parties to the PNCA on behalf of the government of the United States. The PNCA is a complex agreement that provides an opportunity for the region's power producers to maximize the power system's reliability and economy while meeting their multiple-use objectives. The PNCA does not dictate the operation of the resources it coordinates. It is essentially an accounting mechanism that exchanges the power produced among the parties in order to improve the reliability of the system and reduce regional power costs. Project owners retain complete autonomy to operate as needed to meet their multiple-use requirements. The PNCA was executed in 1964 as an important component of regional plans to maximize the Northwest's hydro resource capability. Maximization also included the development of storage projects on the Columbia River in Canada pursuant to the terms of the 1964 Columbia River Treaty. Because of the link between power coordination and Treaty issues, the current parties to the PNCA, currently are contemplating entering into a replacement or renewed power coordination agreement. Because the power coordination agreement is a consensual arrangement, its ultimate provisions must be acceptable to all of its signatories.

  11. Parcelling out the Watershed: The Recurring Consequences of Organising Columbia River Management within a Basin-Based Territory

    Full Text Available This article examines a 75-year history of North America’s Columbia river to answer the question: what difference does a river basin territory actually make? Advocates reason that river basins and watersheds are natural and holistic water management spaces, and can avoid the fragmentations and conflicts endemic to water management within traditional political territories. However, on the Columbia, this reasoning has not played out in practice. Instead, basin management has been shaped by challenges from and negotiations with more traditional jurisdictional spaces and political districts. The recurring result has been 'parcelling out the watershed': coordinating river management to produce a few spreadable benefits, and distributing these benefits, as well as other responsibilities and policy-making influence, to jurisdictional parts and political districts. To provide generous spreadable benefits, river management has unevenly emphasised hydropower, resulting in considerable environmental losses. However, benefits have been widely spread and shared – and over time challengers have forced management to diversify. Thus a river basin territory over time produced patterns of both positive and negative environmental, social, economic, and democratic outcomes. To improve the outcomes of watershed-based water management, we need more interactive and longer-term models attentive to dynamic politics and geographies.

    In Northwest China, water originates from the mountain area and is largely used for irrigation agriculture in the middle reaches. This study investigates the local and remote impact of irrigation on regional climate in the Heihe River Basin, the second largest inland river basin in Northwest China. An irrigation scheme was developed and incorporated into the Weather Research and Forecasting (WRF) model with the Noah-MP land surface scheme (WRF/Noah-MP). The effects of irrigation is assessed by comparing the model simulations with and without consideration of irrigation (hereafter, IRRG and NATU simulations, respectively) for five growth seasons (May to September) from 2009 to 2013. As consequences of irrigation, daily mean temperature decreased by 1.7°C and humidity increased by 2.3 g kg-1 (corresponding to 38.5%) over irrigated area. The temperature and humidity of IRRG simulation matched well with the observations, whereas NATU simulation overestimated temperature and underestimated humidity over irrigated area. The effects on temperature and humidity are generally small outside the irrigated area. The cooling and wetting effects have opposing impacts on convective precipitation, resulting in a negligible change in localized precipitation over irrigated area. However, irrigation may induce water vapor convergence and enhance precipitation remotely in the southeastern portion of the Heihe River Basin.

  13. The Implication of Climate Signal for Precipitation in the Heihe River Basin, Northwest China

    Full Text Available This paper studies the stochastic dynamic variability of precipitation, for the upper, middle, and lower reaches of the Heihe River basin in Northwest China, by employing Mann-Kendall statistic, Pettitt test, and wavelet transform methods. The possible associations with three prominent climatic patterns, El Niño-Southern Oscillation (ENSO, Artic Oscillation (AO, and Indian Ocean Dipole (IOD, are examined by using multiscale wavelet coherence method. No significant trend is identified for the interannual precipitation variability. However, about 2-year significant variability is detected for the lower reach of the Heihe River basin, and this dominating precipitation variability is essentially depicted by AO. The possible influences of ENSO are exerted on long-term timescale, 8–16 years. The obtained knowledge is helpful for the predications of extreme hydroclimatological events and better reservoir operations for regional water resources.

    The relationship between conifer stomata and existing vegetation across tundra, forest-tundra, and closed zones in the Yellowknife area of the Northwest Territories was studied. Conifer stomata were identified in surface samples from lakes in the treeline zone, but were absent in samples from tundra lakes. Stomate analysis was recorded and the results were presented in a concentration diagram plotting stomate concentrations according to vegetation zone. Conifer stomate analysis was not able to resolve differences between forest-tundra and closed forest. Nevertheless, it was suggested that stomate analysis will become an important technique supplementing pollen analysis for reconstructing past tree-line changes since the presence of stomata in lakes make it possible to separate the tundra from forest-tundra and closed forest. The limited dispersal of conifer stomata permitted a better resolution of tree-line boundaries than did pollen. 13 refs., 3 figs.

    Excessive algal growth in streams and rivers from nutrient enrichment can cause costly human health and environmental problems. As part of the US Environmental Protection Agency's Nutrient Scientific Technical Exchange Partnership and Support (N-STEPS) program, we have been developing stressor-response (S-R) models relating nutrients to attached algal (periphyton) communities to help prioritize monitoring for water quality impairments in Oregon (Pacific Northwest, USA) streams and rivers. Existing data from the state and neighboring states were compiled and standardized from the Oregon Department of Environmental Quality, US Environmental Protection Agency, and the US Geological Survey. To develop S-R models, algal community and biomass metrics were compared with nitrogen (N) and phosphorus (P) concentration data, including total, dissolved, and inorganic forms of these nutrients. In total, 928 paired algal-nutrient samples were compiled from the 8 Level-III Ecoregions occurring in Oregon. Relationships between algal biomass metrics and nutrient concentrations were weak, with only ash-free dry mass and standing stock of chlorophyll a showing slight positive relationships across gradients of total N and soluble reactive P concentrations, respectively. In contrast, metrics describing algal community composition, including percent diatoms and abundance of nutrient-sensitive species, showed very strong nonlinear relationships with total N or P concentrations. This suggests that data describing algal community composition can help identify specific nutrient stressors across environmentally-diverse streams and rivers in the Pacific Northwest. Future analyses will examine if nutrient-algal S-R models vary across different hydrological, physiographical, and ecological settings in the region.

    Within the Taklimakan Desert of Northwestern China, an area renowned for its extreme climate and vulnerable ecosystems, lies one of the largest inland rivers in the world, the Tarim River. Because the Tarim River is located in a remote area from the oceans, rainfall is extremely rare (less than 50 mm per year) but potential evaporation is high (3000 mm). Thus, the major source of water discharge comes from snowmelt and glacier-melt in the mountains. Though the water discharge into the Tarim River has experienced an increase over the past ten years, global climate change forecasts predict this water supply to decline within the century. The Tarim River is the major source of water in Northwestern China, and has become the hub of many economic activities related to agriculture and urban life. Over the past 50 years increased activity in the area has led to a severe decline in river flow. Both human and natural ecosystems have been impacted by water diversions. Since rainfall is rare, the majority of vegetation in this area depends solely on groundwater for survival, and plants are experiencing stress caused by decreasing groundwater levels. Recently nearby cities have experienced severe dust storms caused by the shrinking of the vegetative region along the river. SuMaRiO (Sustainable Management of River Oases) is a bundle project between Germany and China working to contribute to a sustainable land management which explicitly takes into account ecosystem functions (ESF) and ecosystem services (ESS). In a transdisciplinary research process, SuMaRiO will identify realizable management strategies, considering social, economic and ecological criteria. SuMaRiO is developing tools to work with Chinese decision makers to implement sustainable land management strategies. In addition, research is being conducted to estimate climate change impacts, floodplain biodiversity, and water runoff characteristics. The overarching goal of SuMaRiO is to support oasis management along

    The 1400 to 1500 My old Kombolgie Formation of the MacArthur Basin of the Northern Territory overlies or has overlain unconformity-type uranium deposits including Jabiluka, Ranger, Koongarra, Nabarlek and the small deposits of the South Alligator River Valley. A brief study of the basal portion of the formation showed it to consist entirely of mature conglomerates and quartzose sandstones. Analysis of the bedding types (planar cross beds, trough cross beds and parallel beds) and other sedimentary structures (mainly ripple marks and parting lineation) fit a braided alluvial plain model. A paleocurrent study utilizing about 400 measurements from nine localities located along the westward-facing 250 kilometer-long erosional escarpment of the Arnhem Land Plateau showed the dominant paleocurrent trend to be from west and northwest towards the east and southeast, with local divergence. The data and interpretation presented are relevant to the supergene model of uranium deposition at the unconformity, for they add to the suggestion that additional uranium deposits similar to Jabiluka Two may underlie the Kombolgie Formation eastward from the present escarpment

    Solution of atomic problem, which comprises atomic weapon creation, required intensive exploration and extraction of radioactive raw material, uranium ores in the first place, as well as other important metals for this purpose. Practical realization of these problems led to formation of many storages of wastes (tail storages) and dumps of mining production. In this connection the problems of the environmental protection from contamination by radioactive and other unhealthy metals appeared. As a result of mining and processing of radioactive and other raw material, which are necessary in atomic industry, a series of tail storages and dumps appeared in the Kyrgyz Republic. The largest of them are the Kara-Balty, Mailuu-Suu, Kavak, Kadamjai and other tail storages of uranium production. Toxic ingredients of the tail storages migrate together with the natural waters. However the regularities of their migration in space and time are studied insufficiently. By this reason it is almost impossible forecasting radiative and other ecological hazard. As an assessment of the measure of migration from territories of uranium plants only summarized the content of the uranium in underground waters, without natural and technogenic (man-caused) component separation is used at present time, though it is obvious, that just a technogenic component must characterize hazard. For solving this problem the discovery 'Phenomenon of uranium-234 and uranium-238 natural separation' and different degree of 2 34U and 2 38U fractioning in natural conditions and during technological processes were used. Essence of the discovery consists in that at transition of uranium from solid uranium-containing formations in liquids (comprising natural waters), which do not dissolve these formations, the enrichment of isotopic mixture by uranium-234 occurs. As a result of this natural waters and hydrogenic uranium derived from them have a surplus of 2 34U toward 2 38U. In technological cycle when deriving the

    The effects of oil and gas exploration activities on bird abundance in the Arctic were investigated. The study examined the impacts of new and oil visible seismic lines within the Kendall Island Bird Sanctuary on the abundance of breeding passerines, Lapland longspur, common redpoll, American tree sparrow, and red-necked phalarope in upland tundra region and sedge-willow habitats. Results of the study showed that the effects on abundance with newer seismic lines were not statistically significant for most groups of birds. However, more birds were seen on reference transects than on seismic lines. The seismic lines had a significant impact on passerines grouped in upland tundra, as well as for sparrows in sedge and willows. Along older seismic lines, passerine abundance was lower than on reference transects in upland tundra. The study demonstrated that seismic lines created between 10 and 30 years ago had persistent vegetative changes that have reduced bird abundance. It was concluded that although the birds were not avoiding lines, some birds appeared to have increased the size of their territories in order to compensate for vegetative changes. 34 refs., 4 tabs.

    Elevated fluoride (F) concentration in groundwater is posing a public health risk in the Manas River Basin (MRB), Northwest China. Based on the characterization of regional groundwater flow, 90 groundwater samples from aquifers were analyzed, along with top-soil leachate and pore-water samples from aquitards. Stable oxygen (δ18O) and hydrogen isotopes, radiocarbon and hydrochemical analyses of the groundwater and pore-water samples were conducted to trace groundwater hydrological and hydrochemical processes and thereby understand the distribution and migration mechanism of F. The groundwater is recharged by meteoric precipitation through vapor condensation processes in the Tianshan Mountains. The F concentration in groundwater samples from this basin ranged from 0.11 to 48.15 mg/L (mean 2.56 mg/L). In 37 of the 90 groundwater samples, the F concentrations were above the safe level for drinking water. The F concentrations progressively increased with the residence time and well depths in the northwest of the alluvial-fluvial plain, where groundwater is overexploited for agricultural and domestic use. Positive correlations between F and sodium (Na)/calcium (Ca) indicate that the enrichment and migration of F are influenced by cation exchange processes under high-Na and alkaline pH conditions. The relationships between δ18O and F and chloride (Cl) concentrations were nonlinear due to leaching and mixing processes. This shows that vertical leaching by irrigation return flow and mixing with pore water are the dominant processes driving the migration of F in the groundwater flow system of MRB, in addition to geochemical processes.

    Decadal scale impacts of exploratory oil and gas drilling activities on native plant communities in the lower Arctic tundra were investigated. The study used historical data from oil and gas exploration activities in the Mackenzie River Delta to assess changes in vegetation composition and environmental gradients at 7 drilling mud sumps located in the Kendall Island Bird Sanctuary. Over a period of 3 decades, the sumps had developed vegetation coverage equivalent in mass to vegetation in undisturbed areas. However, bare soil was observed at ponded sites where salt crusts had formed. The vegetation was composed of forbs, grasses, and tall shrubs that were distinct from surrounding low shrub communities. The area of vegetation around the sump was larger in upland and saline environments. Water around the sumps was associated with thaw subsidence that occurred after construction activities. Changes in drainage, surface salt concentrations, and active-layer depths were seen as the most significant factors in the resulting plant communities. 31 refs., 4 tabs., 7 figs.

    Full Text Available Baseflow is an important component in hydrological modeling. The complex streamflow recession process complicates the baseflow simulation. In order to simulate the snow and/or glacier melt dominated streamflow receding quickly during the high-flow period but very slowly during the low-flow period in rivers in arid and cold northwest China, the current one-reservoir baseflow approach in SWAT (Soil Water Assessment Tool model was extended by adding a slow- reacting reservoir and applying it to the Manas River basin in the Tianshan Mountains. Meanwhile, a digital filter program was employed to separate baseflow from streamflow records for comparisons. Results indicated that the two-reservoir method yielded much better results than the one-reservoir one in reproducing streamflow processes, and the low-flow estimation was improved markedly. Nash-Sutcliff efficiency values at the calibration and validation stages are 0.68 and 0.62 for the one-reservoir case, and 0.76 and 0.69 for the two-reservoir case. The filter-based method estimated the baseflow index as 0.60, while the model-based as 0.45. The filter-based baseflow responded almost immediately to surface runoff occurrence at onset of rising limb, while the model-based responded with a delay. In consideration of watershed surface storage retention and soil freezing/thawing effects on infiltration and recharge during initial snowmelt season, a delay response is considered to be more reasonable. However, a more detailed description of freezing/thawing processes should be included in soil modules so as to determine recharge to aquifer during these processes, and thus an accurate onset point of rising limb of the simulated baseflow.

    Sr 90 contamination of the water flow Dnepr, Pripyat', Sozh, Besed', Iput' rivers is considered. The dynamics of reducing the average year activities of Sr 90 and the variations of the levels of Sr 90 activities in river water during spring-autumn high water are shown. The results of investigation of Sr 90 activity of the sediments of Pripyat' and Braginka rivers are connected with the second effects of the contamination of the river flowing off Sr 90 during high water period. Sr 90 transfer in composition of the flowing off river during 1990-1995 (from Belarus to Ukraine) is being estimated. (authors)

    Full text: Within the framework of the International Cooperation Program in the sphere of the transboundary monitoring of the rivers between the Republics of Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan, and the United States of America ( N avruz , ISTC KR-850 Project), in addition, in the Kyrgyz Republic, the isotopic content (isotopic ratio of 234 U/ 238 U=γ ), and the uranium content (CU) in the waters was measured. The isotopic ratio 234 U/ 238 U=γ of the waters of the rivers Naryn and Kara-Daria basins has no anomalous values of 234 U/ 238 U, which indicates the absence of the man-caused uranium in these rivers. The results of determination of the activity ratio of 234 U/ 238 U and uranium content in the Mailuu-Suu river basin are of great interest. In the upper reaches of the Mailuu-Suu river the uranium content is 0.4 10 -6 g/l (0.8 10 -6 g/l in the flood period), in Mailuu-Suu town (after the tailing dump) - (3 †4) 10 -6 g/l, i.e. this value is an order of magnitude higher, and at the border with Uzbekistan - 1.8 ·10 -6 g/l (3.2 ·10 -6 g/l in the period of flooding), which is lower as compared with the town. Correspondently, there are changes in the activity ratio from 1.39 (in the upper reaches of the river) to 1.05 (in the town), and 1.32 (1.12 during the flood period) at the border with Uzbekistan. This situation indicates, first, the enrichment of the waters of the rivers with the man-caused uranium ( γ=1), and its subsequent sorption along the river stream. The obtained results indicate the absence of the man-caused uranium in the whole stream of the Naryn and Kara-Daria rivers on the territory of the Kyrgyz Republic, and lack of noticeable contamination of the waters of the Mailuu-Suu river with the man-caused uranium from the tailing dumps of the Western Mining-Chemical Plant (WMCP, Mailuu-Suu). It also should be noted that the share of the man-caused uranium, transported to Uzbekistan by the Mailuu-Suu river does not exceed 20-30%, and

    Full Text Available The paper reports on new and previously not well-known data on insufficiently studied fauna of aphids living on coniferous trees in Central Siberia of the basin of Yenisei river. This region is the extensive transect of latitudinal geographic zones from semi-desert in the South to the arctic deserts in the North. That is why this region is very peculiar. This is the reason for insufficient study of regional entomological fauna. Aphids (Homoptera: Aphidoideaare a very taxonomically and ecologically heterogeneous group of insects. The aphids living on conifer trees are notstudied completely on the territory of Yenisei basin. Due to this, the studying of not well-known and economicallyimportant aphids is actual. For example, the insufficient study of regional aphids is confirmed by the fact, that duringthree weeks only of the work for INTAS-94-0930 Project two new aphid species were found and described on thisterritory. Also, the new species of family Mindaridae, which was described in Mongolia in 1980, was found in Siberiafor the first time. These finds indicate the real possibility to describe an interesting conifer aphid complex in the absolutely unstudied forested territory between Angara and Lower Tunguska rivers. Geographical location, dates ofcollection and feeding preferences of different species are described. A general review of Yenisei basin Siberian aphidfauna is suggested for the first time ever.

    Full Text Available Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.

    The authors report here halogen concentrations in pore waters and sediments collected from the Mallik 5L-38 gas hydrate production research well, a permafrost location in the Mackenzie Delta, Northwest Territories, Canada. Iodine and Br are commonly enriched in waters associated with CH 4 , reflecting the close association between these halogens and source organic materials. Pore waters collected from the Mallik well show I enrichment, by one order of magnitude above that of seawater, particularly in sandy layers below the gas hydrate stability zone (GHSZ). Although Cl and Br concentrations increase with depth similar to the I profile, they remain below seawater values. The increase in I concentrations observed below the GHSZ suggests that I-rich fluids responsible for the accumulation of CH 4 in gas hydrates are preferentially transported through the sandy permeable layers below the GHSZ. The Br and I concentrations and I/Br ratios in Mallik are considerably lower than those in marine gas hydrate locations, demonstrating a terrestrial nature for the organic materials responsible for the CH 4 at the Mallik site. Halogen systematics in Mallik suggest that they are the result of mixing between seawater, freshwater and an I-rich source fluid. The comparison between I/Br ratios in pore waters and sediments speaks against the origin of the source fluids within the host formations of gas hydrates, a finding compatible with the results from a limited set of 129 I/I ratios determined in pore waters, which gives a minimum age of 29 Ma for the source material, i.e. at the lower end of the age range of the host formations. The likely scenario for the gas hydrate formation in Mallik is the derivation of CH 4 together with I from the terrestrial source materials in formations other than the host layers through sandy permeable layers into the present gas hydrate zones

    Given their large areal coverage, high carbon densities, unique land surface properties, and disturbance regimes, Canada's diverse high-latitude ecosystems across its multiple Arctic, subarctic and boreal ecozones are integral components of the global and regional climate systems. In northwestern Canada, large portions of these ecozones contain permafrost, i.e., perennially cryotic ground. Here, we describe efforts towards a meso-network of nine eddy covariance towers to measure carbon, water and energy fluxes across the Northwest Territories to shed light on high-latitude carbon and water budgets and their rapidly changing biotic and abiotic controls in response to increasing natural and anthropogenic pressures. Distributed across six research sites (Trail Valley Creek, 68.7°N, 133.3°W; Havikpak Creek, 68.3°N, 133.3°W; Daring Lake, 64.8°N, 111.5°W; Smith Creek, 63.1°N, 123.2°W; Scotty Creek, 63.1°N, 123.2°W; Yellowknife, 62.5°N, 114.4°W), the meso-network spans the central portion of the extended ABoVE Study Domain, covering two ecozones (Taiga Plains, Southern Arctic) with differing permafrost regimes (sporadic, discontinuous, continuous), climatic settings (coastal, interior), and seven high-latitude ecosystem types: forested permafrost peat plateau, permafrost-free collapse-scar bog, subarctic woodland, mixed and dwarf-shrub tundra, and sedge fen. With our contribution, we report on the current status of the meso-network development and present results from various synthesis activities examining the role of climatic setting and resulting tundra carbon and water budgets, quantifying the impact of permafrost thaw and associated wetland expansion on boreal forest carbon and water budgets, and determining the relative importance of treeline advance compared to shrub proliferation on tundra carbon and water budgets.

    Youth in Canada's Northwest Territories (NWT) experience sexual and mental health disparities. Higher rates of sexual and mental health concerns among lesbian, gay, bisexual, transgender and queer (LGBTQ) youth in comparison with heterosexual and cisgender peers have been associated with stigma and discrimination. Although LGBTQ youth in the NWT are situated at the nexus of Northern and LGBTQ health disparities, there is little known about their health, well-being and experiences of stigma. This short communication discusses the process of developing a LGBTQ youth community-based research programme in the NWT. We developed an interdisciplinary research team of LGBTQ and allied young adults, including indigenous and non-indigenous researchers, community organisers and service providers in the NWT. We conducted meetings in Yellowknife with LGBTQ youth (n=12) and key stakeholders (n=15), including faculty, students, community groups and health and social service providers. Both meetings included LGBTQ and allied participants who were LGBTQ, indigenous, youth and persons at the intersection of these identities. LGBTQ youth participants discussed community norms that devalued same sex identities and stigma surrounding LGBTQ-specific services and agencies. Stigma among LGBT youth was exacerbated for youth in secondary schools, gender non-conforming and transgender youth and young gay men. In the stakeholder meeting, service providers discussed the importance of integrating LGBTQ issues in youth programmes, and LGBTQ community groups expressed the need for flexibility in service delivery to LGBTQ youth. Stakeholders identified the need to better understand the needs of indigenous LGBTQ youth in the NWT. Community-based LGBTQ groups, researchers and health and social service providers are interested in addressing LGBTQ youth issues in the NWT. The emergence of LGBTQ community building, support groups and activism in Northern Canada suggests that this is an opportune time

    Considerable progress has been made in recent decades towards understanding northern ecosystem structure and function in the context of resilience theory. For example, there is increasing understanding that wildfire activity is overwhelming the resilience mechanisms of conifer species, shifting forest composition toward deciduous cover in some boreal regions. Relative to forests and grasslands, we have less knowledge on what governs the response of northern peatlands to disturbance, including drought, wildfire, and permafrost thaw. The majority of peatland research to date has instead focused on ecological and hydrological measurements across fen-to-bog or hummock-to-hollow gradients. It was only recently appreciated that fire serves as an important agent of successional change in northern peatlands, as recent studies show that peat accumulation and the function of peatlands as net carbon sinks requires light to moderate fire activity. In this presentation, we will synthesize results from water table and vegetation manipulation experiments, continuous ecosystem-scale measurements of carbon, energy and water fluxes, and observations across gradients of fire severity and permafrost thaw to derive a mechanistic framework of peatland ecological and hydrological resilience. In particular, we will highlight the past decade of observations made at the Scotty Creek Research Station in the Northwest Territories as well as the Alaska Peatland Experiment (APEX) in interior Alaska. Our research shows that vegetation, particularly deep rooting early successional species and late successional mosses, play a critical role in maintaining nutrient cycling and ecosystem carbon balance in a peat accumulating state. Peatlands also govern how the surrounding landscape responds to drought, fire, and permafrost thaw. Future research needs to consider the resilience of northern ecosystems at a variety of spatio-temporal scales through a combination of ground measurements, remote sensing

    Full Text Available Background: Youth in Canada's Northwest Territories (NWT experience sexual and mental health disparities. Higher rates of sexual and mental health concerns among lesbian, gay, bisexual, transgender and queer (LGBTQ youth in comparison with heterosexual and cisgender peers have been associated with stigma and discrimination. Although LGBTQ youth in the NWT are situated at the nexus of Northern and LGBTQ health disparities, there is little known about their health, well-being and experiences of stigma. This short communication discusses the process of developing a LGBTQ youth community-based research programme in the NWT. Methods: We developed an interdisciplinary research team of LGBTQ and allied young adults, including indigenous and non-indigenous researchers, community organisers and service providers in the NWT. We conducted meetings in Yellowknife with LGBTQ youth (n=12 and key stakeholders (n=15, including faculty, students, community groups and health and social service providers. Both meetings included LGBTQ and allied participants who were LGBTQ, indigenous, youth and persons at the intersection of these identities. Results: LGBTQ youth participants discussed community norms that devalued same sex identities and stigma surrounding LGBTQ-specific services and agencies. Stigma among LGBT youth was exacerbated for youth in secondary schools, gender non-conforming and transgender youth and young gay men. In the stakeholder meeting, service providers discussed the importance of integrating LGBTQ issues in youth programmes, and LGBTQ community groups expressed the need for flexibility in service delivery to LGBTQ youth. Stakeholders identified the need to better understand the needs of indigenous LGBTQ youth in the NWT. Conclusions: Community-based LGBTQ groups, researchers and health and social service providers are interested in addressing LGBTQ youth issues in the NWT. The emergence of LGBTQ community building, support groups and activism

    Organochlorine pesticides (OCPs) are a sub-group of persistent organic pollutants (POPs), which have raised the concerns from researchers all around the world for several decades. But very little research has been conducted on POPs in the arid zone of Northwest China. More than 100 soil and sediment samples were collected from Kaidu-Peacock River of Xinjiang, Northwest of China, to investigate the organochlorine pesticides (OCPs) in this region analysed by the gas chromatograph equipped with a mass selective detector (GC-MSD). Our pre-study in 2006 (Chen et al. 2011) in the same region, showed that OCPs except o,p'-DDT were detected in sediments from the Peacock River. Similar results were found in the whole river catchment in this investigation. DDTs, HCHs, chlordanes and endosulfans were the dominant OCPs residual in the soil and sediments. This study confirmed that POPs, such as OCPs in this region were contributed to by both local emissions and long-term atmospheric transport and may pose risks to human health and the ecosystem.

    This paper focuses on the sources, pollution status and potential ecology risks of heavy metals (Cr, Cu, Hg, As, Cd, Pb, and Zn) in the surface water, top sediment of river bed and soil along banks of Bortala River, which locates in the oasis region of Xinjiang, northwest China. Results showed that: (1) As a whole, contents of 7 tested heavy metals of Bortala River were low, while the maximum values of Hg, Cd, Pb, and Cr in the river water were significantly higher than those of Secondary Category of the Surface Water Quality Standards of People's Republic of China (GB 3838-2002) and Drinking Water Guideline from WHO. Analysis showed that the heavy metals contents of top sediment on river bed and soils along river banks were significantly higher than those of the river water. (Correlation analysis and enrichment factor (EF) calculation showed that in the river water, top sediment on river bed and soils along river banks, Hg, Cd, Pb, and Cr mainly originated from industrial emissions, urban and rural anthropogenic activities, transportation and agricultural production activities; While Cu, Zn, and As mainly originated from natural geological background and soil parent materials. (3) Pollution assessment showed that in three matrices, the single factor pollution index(Pi) and the integrated pollution index (Pz) of 7 heavy metals were all lower than 1, and they all belonged to safe and clean levels. (4) Potential ecology risk evaluation showed that as a whole the single factor potential ecological risk (Eir) and the integrated potential ecology risks (RI) of 7 heavy metals were relatively low, and would not cause threats to the health of water and soil environment of river basin, while the potential ecology risks of Cd, Hg, Pb, and Cr were significantly higher than those of other heavy metals.

    The Echo Bay stratovolcano complex and Contact Lake Belt of the Great Bear Magmatic Zone, Northwest Territories, host a series of coalescing Paleoproterozoic hydrothermal systems that affected an area of several hundred square kilometers. They were caused by intrusion of synvolcanic diorite-monzodioritic plutons into andesitic host rocks, producing several characteristic hydrothermal assemblages. They include early and proximal albite, magnetite-actinolite-apatite, and potassic (K-feldspar) alteration, followed by more distal hematite, phyllic (quartz-sericite-pyrite), and propylitic (chlorite-epidote-carbonate±sericite±albite±quartz) alteration, and finally by late-stage polymetallic epithermal veins. These alteration types are characteristic of iron oxide copper-gold deposits, however, with distal and lower-temperature assemblages similar to porphyry Cu systems. Magnetite-actinolite-apatite alteration formed from high temperature (up to 560 °C) fluids with average salinity of 12.8 wt% NaCl equivalent. The prograde propylitic and phyllic alteration stages are associated with fluids with temperatures varying from 80 to 430 °C and a wide salinity range (0.5-45.6 wt% NaCl equivalent). Similarly, wide fluid temperature (104-450 °C) and salinity (4.2-46.1 wt% NaCl equivalent) ranges are recorded for the phyllic alteration. This was followed by Cu-Ag-U-Zn-Co-Pb sulfarsenide mineralization in late-stage epithermal veins formed at shallow depths and temperatures from 270 °C to as low as 105 °C. The polymetallic veins precipitated from high salinity (mean 30 wt% NaCl equivalent) dense fluids (1.14 g/cm3) with a vapor pressure of 3.8 bars, typical of epithermal conditions. Fluid inclusion evidence indicates that mixed fluids with evolving physicochemical properties were responsible for the formation of the alteration assemblages and mineralization at Mag Hill. An early high temperature, moderate salinity, and magmatic fluid was subsequently modified variably by

    Persistent organic pollutants like organochlorine pesticides continue to contaminate large areas worldwide raising questions concerning their management. We designed and tested a method to link soil and water pollution in the watershed of the Galion River in Martinique. We first estimated the risk of soil contamination by chlordecone by referring to past use of land for banana cultivation and took 27 soil samples. We then sampled surface waters at 39 points and groundwater at 16 points. We tested three hypotheses linked to the source of chlordecone pollution at the watershed scale: (i) soils close to the river, (ii) soils close to the sampling point, (iii) throughout the sub-watershed generated at the sampling point. Graphical and statistical analysis showed that contamination of the river increased when it passed through an area with contaminated plots and decreased when it passed through area not contaminated by chlordecone. Modeling showed that the entire surface area of the watershed contributed to river pollution, suggesting that the river was mainly being contaminated by the aquifers and groundwater flows. Our method proved to be a reliable way to identify areas polluted by chlordecone at the watershed scale and should help stakeholders focus their management actions on both hot spots and the whole watershed.

    The construction of the hydroelectric power constructions Gabcikovo changed the landscape near the Danube river. After the construction of the supply and falling-off canals with the hydroelectric power plant the artificial island with three seats were formed. This territory has high ecologic quality with good developed organisation of the bio-centers, bio-corridors and interaction elements with the specifically oriented agriculture. In this territory the development of the socio-economic activities were substantially limited regard to the protection of the water sources, protection of the forests, protected territories of the nature and communication accessibility. Therefore, the centre of the gravity of the territory development must be oriented in the ecology

    Pancontinental Mining Limited acquired exploration rights over an area in the East Alligator River Region, Northern Territory, Australia, in 1970. Subsequently, Getty Oil Development Company Limited acquired a substantial minority interest in the property. The Jabiluka deposits were discovered during the course of exploration and are currently the largest of the four major uranium deposits in the East Alligator River Region. This region at present contains 24% of the western world's reasonably assured resources of uranium. The exploration techniques employed during primary and secondary exploration on the property between 1971 and 1975 and during the delineation of the Jabiluka deposits are discussed in detail. The case history illustrates the exploration philosophy which was successfully employed on the Jabiluka property. The philosophy encompasses the following points: The need for an assessment on the limits of airborne radiometric surveys; the necessity for detection and evaluation of point source anomalies; the necessity for exploration along extensions of favourable lithologies; and the desirability of modification of exploration techniques on different types of anomalies. Some aspects of this philosophy may be useful in exploration for similar stratabound uranium deposits in other areas. (author)

    Stringent environmental controls have been applied to the Ranger mine, in the Northern Territory of Australia, because of its location in an area of outstanding natural and cultural values. The adjacent Kakadu National Park contains a wild and extensive biodiversity, striking landscapes, ancient Aboriginal rock art and a living Aboriginal culture. A special regime of biological, radiological and chemical monitoring has been applied to protect the environment and detect even very low intensity impacts. The results from this regime demonstrate to the government and general public that the high conservation values of the national park around the mine are being properly protected. This paper describes the techniques used to measure environmental impact at Ranger, and summarizes the results of over 20 years of monitoring. The overwhelming conclusion is that a very high standard of environmental protection has been achieved. (author)

    The tropical climate of the Alligator Rivers Region (ARR) has a distinctive wet-dry cycle , resulting in seasonal flows in the creeks and rivers of its catchments. The present study, begun in August 1978, was aimed at developing an ecological monitoring system that would detect any changes to the freshwater fish communities brought about by recent uranium mining and processing in the lowlands of the ARR. The focus of the synecological studies, was a description of spatial and temporal patterns in the community structure of the fish fauna. Interpretation of these patterns was made possible by the collection of detailed environmental data from the study sites. It was found that of the ARR seasonal changes in environmental conditions were so marked that they often obscured the effects of environmental gradients along a watercourse and differing environmental conditions characteristics of different types of waterbody. Hence it may not be entirely satisfactory to define environmental zones in these catchments based on overall environmental conditions through the whole seasonal cycle, because changes in any one such zone between seasons result in very marked changes in the fish communities of habitats in that zone. 34 refs., 22 tabs., 45 figs., 3 maps

    The geography and hydrology of the area of the excursion are described. There is much damage due to brown coal strip mining operations. Ground water was drained through a canal leading to the Erft River. The water in nearby springs is rich in Fe which repels plant life. The canal contains only a few blue algae (Oscillatoria splendida) and filamentous green algae (Ulothrix tenerrima) which tolerate high Fe concentrations. The Erft shore plant population includes Sparganium erectum, Potamogeton natans, P. pectinatus and Ranunculus fluitans. On flowering plants and stones, diatoms, various green algae (Cladophora glomerata, Stigeoclonium tenue, Oedogonium capillare) and the tropical red alga Compsopogon hookeri were found. The macrozoobenthos is composed mainly of snails (Bithynia tenaculata, Lumnaea ovata, Physa fontinalis, P. acuta and worms of North American origin (Dugesia tifrina, Dendrocoelum lacteum and Planaria lugubris). The Isopoda included Asellus coxalis and A. aquaticus. Leeches (Herpobdella octoculata) and insect larvae (Chironomids, Limnephilids) were also found.

    Full Text Available The inland river watersheds of arid Northwest China represent an example of how, in recent times, climatic warming has increased the complexity of Earth’s hydrological processes. In the present study, the linear and nonlinear characteristics of the runoff response to temperature and precipitation were investigated in the Qira River basin, located on the northern slope of the Kunlun Mountains. The results showed that average temperature on annual and seasonal scales has displayed a significantly increasing trend, but this has not been reflected in accumulated precipitation and runoff. Using path analysis, a positive link between precipitation and runoff was found both annually and in the summer season. Conversely, it was found that the impact of temperature on runoff has been negative since the 1960s, attributable to higher evaporation and infiltration in the Qira River basin. Over the past 50 years, abrupt changes in annual temperature, precipitation and runoff occurred in 1997, 1987 and 1995, respectively. Combined with analysis using the correlation dimension method, it was found that the temperature, precipitation and runoff, both annually and seasonally, possessed chaotic dynamic characteristics, implying that complex hydro-climatic processes must be introduced into other variables within models to describe the dynamics. In addition, as determined via rescaled range analysis, a consistent annual and seasonal decreasing trend in runoff under increasing temperature and precipitation conditions in the future should be taken into account. This work may provide a theoretical perspective that can be applied to the proper use and management of oasis water resources in the lower reaches of river basins like that of the Qira River.

    Full Text Available Taking the Yarkand River as an example, this paper conducted an integrative approach combining the Durbin-Watson statistic test (DWST, multiple linear regression (MLR, wavelet analysis (WA, coefficient of determination (CD, and Akaike information criterion (AIC to analyze the climatic-hydrological process of inland river, Northwest China from a multitime scale perspective. The main findings are as follows. (1 The hydrologic and climatic variables, that is, annual runoff (AR, annual average temperature, (AAT and annual precipitation (AP, are stochastic and, no significant autocorrelation. (2 The variation patterns of runoff, temperature, and precipitation were scale dependent in time. AR, AAT, and AP basically present linear trends at 16-year and 32-year scales, but they show nonlinear fluctuations at 2-year and 4-year scales. (3 The relationship between AR with AAT and AP was simulated by the multiple linear regression equation (MLRE based on wavelet analysis at each time scale. But the simulated effect at a larger time scale is better than that at a smaller time scale.

    Integrated watershed study and river basin management needs integrated database and integrated hydrological and water resource models. We define digital watershed as a web-based information system that integrates data from different sources and in different scales through both information technology and hydrological modeling. In the last two years, a “digital basin” of the Heihe River Basin, which is a well-studied in-land catchment in China’s arid region was established. More than 6 Gb of in situ observation data, GIS maps, and remotely sensed data have been uploaded to the Heihe web site. Various database and dynamic web techniques such as PHP, ASP, XML, VRML are being used for data service. In addition, the DIAL (Data and Information Access Link), IMS (Internet Map Server) and other Web-GISs are used to make GIS and remote sensing datasets of the Heihe River Basin available and accessible on the Internet. We also have developed models for estimating the evapotranspiration, bio-physical parameters, and snow runoff. These methods can be considered as the elements to build up the integrated watershed model that can be used for integrated management of the Heihe River Basin. The official domain name of the digital Heihe River Basin is heihe.westgis.ac.cn

    The Preto River, located in the northwest of São Paulo State, receives a total wastewater load of 15.150 kg DBO day-1, from which 13.685 kg DBO day-1 (90.5%) corresponds to domestic sewage, and the city of São José do Rio Preto contributes with 12.400 kg DBO day-1 (90% of domestic sewage). During the period from August 1990 through January 1991, monthly sampling was carried out to evaluate the use of macroalgae as bioindicator of organic pollution. Five sampling sites were established along the main river and the following variables were analised: temperature, conductance, turbidity, dissolved oxygen, BOD, COD, total and fecal coliforms, and composition and abundance of macroalgal communities. Data were submitted to analysis of variance, correlation coefficient, cluster analysis (four different approaches) and converted to biological indices (species deficit, relative pollution, saprobity, diversity and uniformity indices). A wide range in water quality was found (particularly for conductance, oxygen, BOD and COD) among the sampling sites, which were classified into three groups (polluted, moderately polluted and unpolluted/weakly polluted). As regards the occurrence and abundance of macroalgae the Rhodophyta were found only in unpolluted or weakly polluted sites, whereas Cyanophyta occurred mostly under high pollution load; the Chlorophyta species were observed under a wide range of conditions. Among the biological indices, saprobity was the most sensitive and correlated to all water variables and the other indices. Cluster analyses showed that the composition of macroalgal communities was consistent with the levels of organic pollution in the Preto River.

    Water resource is of fundamental importance to the society and ecosystem in arid endorheic river basins, and water-use conflicts between upstream and downstream are usually significant. Heihe river basin (HRB) is the second largest endorheic river basin in china, which is featured with dry climate, intensively irrigated farmlands in oases and significant surface water-groundwater interaction. The irrigation districts in the middle HRB consume a large portion of the river flow, and the low HRB, mainly Gobi Desert, has an extremely vulnerable ecological environment. The water resources management has significantly altered the hydrological processes in HRB, and is now facing multiple challenges, including decline of groundwater table in the middle HRB, insufficient environmental flow for the lower HRB. Furthermore, future climate change adds substantial uncertainty to the water system. Thus, it is imperative to have a sustainable water resources management in HRB in order to tackle the existing challenges and future uncertainty. Climate projection form a dynamical downscaled climate change scenario shows precipitation will increase at a rate of approximately 3 millimeter per ten years and temperature will increase at a rate of approximately 0.2 centigrade degree per ten years in the following 50 years in the HRB. Based on an integrated ecohydrological model, we evaluated how the climate change and agricultural development would collaboratively impact the water resources and ecological health in the middle and lower HRB, and investigated how the water management should cope with the complex impact.

    The runoff in alpine river basins where the runoff is formed in nearby mountainous areas is mainly affected by temperature and precipitation. Based on observed annual mean temperature, annual precipitation, and runoff time-series datasets during 1958–2012 within the Kaidu River Basin, the synchronism of runoff response to climate change was analyzed and iden-tified by applying several classic methods, including standardization methods, Kendall's W test, the sequential version of the Mann-Kendall test, wavelet power spectrum analysis, and the rescaled range (R/S) approach. The concordance of the nonlinear trend variations of the annual mean temperature, annual precipitation, and runoff was tested significantly at the 0.05 level by Kendall's W method. The sequential version of the Mann-Kendall test revealed that abrupt changes in annual runoff were synchronous with those of annual mean temperature. The periodic characteristics of annual runoff were mainly consistent with annual precipitation, having synchronous 3-year significant periods and the same 6-year, 10-year, and 38-year quasi-periodicities. While the periodic characteristics of annual runoff in the Kaidu River Basin tracked well with those of annual precipitation, the abrupt changes in annual runoff were synchronous with the annual mean temperature, which directly drives glacier- and snow-melt processes. R/S analysis indicated that the annual mean temperature, annual precipitation, and runoff will continue to increase and remain synchronously persistent in the future. This work can im-prove the understanding of runoff response to regional climate change to provide a viable reference in the management of water resources in the Kaidu River Basin, a regional sustainable socio-economic development.

    Full Text Available This paper is focused on the probability modeling with a range of distribution models over two inland river basins in China, together with the estimations of return levels on various return periods. Both annual and seasonal maximum precipitations (MP are investigated based on daily precipitation data at 13 stations from 1960 to 2010 in Heihe River and Shiyang River basins. Results show that GEV, Burr, and Weibull distributions provide the best fit to both annual and seasonal MP. Exponential and Pareto 2 distributions show the worst fit. The estimated return levels for spring MP show decreasing trends from the upper to the middle and then to the lower reaches totally speaking. Summer MP approximates to annual MP both in the quantity and in the spatial distributions. Autumn MP shows a little higher value in the estimated return levels than Spring MP, while keeping consistent with spring MP in the spatial distribution. It is also found that the estimated return levels for annual MP derived from various distributions differ by 22%, 36%, and 53% on average at 20-year, 50-year, and 100-year return periods, respectively.

    The Ecological Water Transfer and Rehabilitation Project in the arid inland area of northwest China is an important measure in restoring a deteriorated ecosystem. However, the sustainability of the project is affected by many socio-economic factors. This article examines the attitudes of the local populace toward the project, its impact on the livelihood of the people, and the positive effects of water-efficient agricultural practices in Ejina County. Related data were collected through questionnaire surveys and group discussions. The results identified three critical issues that may influence the sustainability of the project in the study area. The first issue relates to the impact of the project on the livelihood of local herdsmen. The potential for the sustainability of the project is compromised because the livelihood of the herdsmen greatly depends on the compensation awarded by the project. The second issue is that the project did not raise the water resource utilization ratio, which may undermine its final purpose. Finally, the compensation provided by the project considers losses in agriculture, but neglects the externalities and public benefit of eco-water. Thus, appropriate compensation mechanisms should be established and adopted according to local economic, environmental, and social conditions. Some recommendations for improving the sustainability of the project are provided based on the results of this study.

    Land use change and climate variability are two key factors impacting watershed hydrology, which is strongly related to the availability of water resources and the sustainability of local ecosystems. This study assessed separate and combined hydrological impacts of land use change and climate variability in the headwater region of a typical arid inland river basin, known as the Heihe River Basin, northwest China, in the recent past (1995–2014) and near future (2015–2024), by combining two land use models (i.e., Markov chain model and Dyna-CLUE) with a hydrological model (i.e., SWAT). The potential impacts in the near future were explored using projected land use patterns and hypothetical climate scenarios established on the basis of analyzing long-term climatic observations.

    Water allocation unbalance is the most important driving force of ecological degradation in the Heihe River Basin, where it seems the lifeblood of environment and human society. Water commute complex and frequent in soil, atmosphere, surface and ground face. The balance analysis of Water's transformation based on the WRF (Weather Research Forecasting) and SWAT (Soil and Water Assessment Tool) simulations, puts forward the application of land governance in arid and semi-arid region. In this study, we designed an irrigation scheme using local field experiences and incorporated the irrigation scheme into WRF/Noah-MP model. Then, to test the effects of irrigation scheme on performance of WRF/Noah-MP model, we carried out two simulations with the Heihe watershed, Northwest China, as a case study area. Firstly, the irrigation simulation is meanly about 860 mm across all of 671 cropland grid cells within the Heihe watershed and gradually increases from about 500 mm nearby the foot of Qilian Mountain to the maximum about 1500 mm in the middle and lower reach of Heihe River. Both of regional mean value and spatial heterogeneity are close to ground measurements. Secondly, the irrigation simulation dramatically reduced the mean bias of specified humidity to -0.47 g kg-1 (accounting for 6.0% of observation) and RMSE of temperature to 0.47 °C, respectively, since the irrigation enhanced the surface latent heat and weakened sensible heat to atmosphere. Thirdly, Across the 8 agricultural sites, the correlation coefficient and RMSE increased from 0.75 to 0.80. Finally, we found the surface runoff will increase by 0.46% with SWAT model at irrigation months. Therefore, the irrigation may led to expansion of cultivated land through transformation from groundwater to surface water at some degree. Water authorities should strengthen the tough water management measures to implement measures of total quantity control and raise the efficiency of water resources.

    Land use change and climate variability are two key factors impacting watershed hydrology, which is strongly related to the availability of water resources and the sustainability of local ecosystems. This study assessed separate and combined hydrological impacts of land use change and climate variability in the headwater region of a typical arid inland river basin, known as the Heihe River Basin, northwest China, in the recent past (1995-2014) and near future (2015-2024), by combining two land use models (i.e., Markov chain model and Dyna-CLUE) with a hydrological model (i.e., SWAT). The potential impacts in the near future were explored using projected land use patterns and hypothetical climate scenarios established on the basis of analyzing long-term climatic observations. Land use changes in the recent past are dominated by the expansion of grassland and a decrease in farmland; meanwhile the climate develops with a wetting and warming trend. Land use changes in this period induce slight reductions in surface runoff, groundwater discharge and streamflow whereas climate changes produce pronounced increases in them. The joint hydrological impacts are similar to those solely induced by climate changes. Spatially, both the effects of land use change and climate variability vary with the sub-basin. The influences of land use changes are more identifiable in some sub-basins, compared with the basin-wide impacts. In the near future, climate changes tend to affect the hydrological regimes much more prominently than land use changes, leading to significant increases in all hydrological components. Nevertheless, the role of land use change should not be overlooked, especially if the climate becomes drier in the future, as in this case it may magnify the hydrological responses.

    Full Text Available The vegetation response to climatic factors is a hot topic in global change research. However, research on vegetation in Shule River Basin, which is a typical arid region in northwest China, is still limited, especially at micro scale. On the basis of Moderate-resolution Imaging Spectroradiometer (MODIS Normalized Difference Vegetation Index (NDVI data and daily meteorological data, employing panel data models and other mathematical models, the aim of this paper is to reveal the interactive relationship between vegetation variation and climatic factors in Shule River Basin. Results show that there is a widespread greening trend in the whole basin during 2000–2015, and 80.28% of greening areas (areas with vegetation improvement are distributed over upstream region, but the maximum vegetation variation appears in downstream area. The effects of climate change on NDVI lag about half to one month. The parameters estimated using panel data models indicate that precipitation and accumulated temperature have positive contribution to NDVI. With every 1-mm increase in rainfall, NDVI increases by around 0.223‰ in upstream area and 0.6‰ in downstream area. With every 1-°C increase in accumulated temperature, NDVI increases by around 0.241‰ in upstream area and 0.174‰ in downstream area. Responses of NDVI to climatic factors are more sensitive when these factors are limiting than when they are not limiting. NDVI variation has performance in two seasonal and inter-annual directions, and the range of seasonal change is far more than that of inter-annual change. The inverted U-shaped curve of the variable intercepts reflects the seasonal change. Our results might provide some scientific basis for the comprehensive basin management.

    The present study aimed to assess the potential ecological risk of heavy metals and nutrient accumulation in polytunnel greenhouse soils in the Yellow River irrigation region (YRIR), Northwest China, and to identify the potential sources of these heavy metals using principal component analysis. Contents of available nitrogen (AN), phosphorus (AP), and potassium (AK) in the surface polytunnel greenhouse soils (0-20 cm) varied from 13.42 to 486.78, from 39.10 to 566.97, and from 21.64 to 1,156.40 mg kg(-1), respectively, as well as AP, soil organic matter (SOM) and AK contents tended to increase significantly at the 0-20- and 20-40-cm soil layers. Heavy metal accumulations occurred in the polytunnel greenhouse soils as compared to arable soils, especially at a depth of 20 cm where Cd, Zn and Cu contents were significantly higher than arable soil. Cd and As were found to be the two main polluting elements in the greenhouse soils because their contents exceeded the thresholds established for greenhouse vegetable production HJ333-2006 in China and the background of Gansu province. It has been shown that Cd, Cu, Pb and Zn at the 0-20-cm soil layer were derived mainly from agricultural production activities, whereas contents of Cr and Ni at the same soil layer were determined by 'natural' factors and As originated from natural sources, deposition and irrigation water.

    We developed Columbia River streamflow reconstructions using a network of existing, new, and updated tree-ring records sensitive to the main climatic factors governing discharge. Reconstruction quality is enhanced by incorporating tree-ring chronologies where high snowpack limits growth, which better represent the contribution of cool-season precipitation to flow than chronologies from trees positively sensitive to hydroclimate alone. The best performing reconstruction (back to 1609 CE) explains 59% of the historical variability and the longest reconstruction (back to 1502 CE) explains 52% of the variability. Droughts similar to the high-intensity, long-duration low flows observed during the 1920s and 1940s are rare, but occurred in the early 1500s and 1630s-1640s. The lowest Columbia flow events appear to be reflected in chronologies both positively and negatively related to streamflow, implying low snowpack and possibly low warm-season precipitation. High flows of magnitudes observed in the instrumental record appear to have been relatively common, and high flows from the 1680s to 1740s exceeded the magnitude and duration of observed wet periods in the late-19th and 20th Century. Comparisons between the Columbia River reconstructions and future projections of streamflow derived from global climate and hydrologic models show the potential for increased hydrologic variability, which could present challenges for managing water in the face of competing demands

    River floodplains are vital natural features that store floodwaters, improve water quality, provide habitat, and create recreational opportunities. Recent studies have shown that strong interactions among flooding, channel and sediment movement, vegetation, and groundwater create a dynamic shifting habitat mosaic that promotes biodiversity and complex food webs. Multiple physical and environmental processes interact within these systems to influence forest productivity, including water availability, nutrient supply, soil texture, and disturbance history. This study is designed to quantify the role of groundwater depth and meteorology in determining spatial and temporal patterns of net primary productivity (NPP) within the Nyack floodplain of the Middle Fork Flathead River, Northwestern Montana. We examine three intensive field sites composed of mature, mixed deciduous and evergreen conifer forest with varying hydrologic and vegetative characteristics. We use a modified Biome-BGC ecosystem process model with field-collected data (LAI, increment growth cores, groundwater depth, vegetation sap-flow, and local meteorology) to describe the effects of floodplain groundwater dynamics on vegetation community structure, and carbon/nitrogen cycling. Initial results indicate that conifers are more sensitive than deeper-rooted deciduous species to variability in groundwater depth and meteorological conditions. Forest productivity also shows a non-linear response to groundwater depth. Sites with intermediate groundwater depths (0.2-0.5m) allow vegetation to maintain connectivity to groundwater over longer periods during the growing season, are effectively uncoupled from atmospheric constraints on photosynthesis, and generally have greater productivity. Shallow groundwater sites (<0.2m) are less productive due to the indirect effects of reduced soil aerobic decomposition and reduced plant available nitrogen.

    Data of the ecological-hydrogeological fieldwork at the Predvolzhye region of the Republic of Tatarstan were analyzed. A geofiltration model of the Buinsk region area near the village of Stary Studenets in the territory of the Republic of Tatarstan was constructed by the PM5 software package. The model can be developed to become the basis for estimation of the groundwater reserves of the territory, modeling the operation of water intake wells, designing the location of water intake wells, and evaluation of their operational capabilities, and constructing sanitary protection zones.

    Samples of muscle from 120 black bears (Ursus americanus), 11 grizzly bears (Ursus arctos), and 27 wolves (Canis lupus) collected in the Dehcho Region of the Northwest Territories from 2001 to 2010 were examined for the presence of Trichinella spp. larvae using a pepsin-HCl digestion assay. Trichinella spp. larvae were found in eight of 11 (73%) grizzly bears, 14 of 27 (52%) wolves, and seven of 120 (5.8%) black bears. The average age of positive grizzly bears, black bears, and wolves was 13.5, 9.9, and approximately 4 yr, respectively. Larvae from 11 wolves, six black bears, and seven grizzly bears were genotyped. Six wolves were infected with T. nativa and five with Trichinella T6, four black bears were infected with T. nativa and two with Trichinella T6, and all seven grizzly bears were infected with Trichinella T6 and one of them had a coinfection with T. nativa. This is the first report of T. nativa in a grizzly bear from Canada. Bears have been linked to trichinellosis outbreaks in humans in Canada, and black bears are a subsistence food source for residents of the Dehcho region. In order to assess food safety risk it is important to monitor the prevalence of Trichinella spp. in both species of bear and their cohabiting mammalian food sources.

    Full text: This report presents the main investigation results of general physical-and-chemical parameters of water, as well as macro- and micro element composition of water and other objects of the environment taken in Syrdariya river basin at the territory of Kazakhstan during 6 expeditions. Basic emphasis here was placed on new results of the last expedition. Physical-and-chemical parameters of water (E i ; μSm/cm - specific conductivity; TDC, g/1 - total amount of dissolved substances;g/1 - mineralization, pH degree; ORP, mV - reductive-oxidative potential) were determined with the help of the 'Hydrolab' device. For study of macro- and microelement composition of the environment objects the were used X-Ray-fluorescent analyses (XRFA), NAA and γ-spectrornetry methods. All analytical methods (including sample preparation) used in these investigations. According to investigation results of chemical-and-physical features of water of the Syrdariya river and its tributaries there is determined. That overage value for pH was 8.0+0.2 and reductive-oxidative potential (ORP) was 400+40 mV. During the all expeditions a change of E c and TDC value was revealed in headwaters of the Syrdariya river, where its tributaries exerts a considerable influence. Especially, it is determined that waters of the Keles and Kurkeles river are characterized by high physical and chemical indicators: TDC - up to 2.6 g/l, E c - up to 4000 μSm/cm. Down the last tributary (the Arys river) there was no any seasonal changes determined in values of these parameters. On this run of the Syrdariya river average value for E c is (1620+80) μSm/cm and for TDC is (1.04+0.05) g/l. According to the investigation results of the element composition of the environment objects there were revealed high concentrations of Cr, Fe, Co, Ni, Zn, As, La, Ce, Th in bottom sediments of headwaters of the Syrdariya river (above the Shardara reservoir). One can suppose that these microelements come with water of Keles

    The Brightening Our Home Fires (BOHF) project was conceptualized as an exploratory project to examine the issue of the prevention of foetal alcohol spectrum disorder (FASD) from a women's health perspective in the Northwest Territories (NT). While dominant discourse suggests that FASD is preventable by abstention from alcohol during pregnancy, a broader perspective would indicate that alcohol and pregnancy is a far more complex issue, that is, bound in location, economics, social and cultural views of health. This project was prevention focused and a social determinant of health (SDH) perspective informed this research. The BOHF project was a qualitative research project using a participatory action research framework to examine women's health and healing in the north. The methodology utilized was Photovoice. Women were provided training in digital photography and given cameras to use and keep. The primary research question utilized was: What does health and healing look like for you in your community? Women described their photos, individually or in groups around this central topic. This research was FASD informed, and women participants were aware this was an FASD prevention funded project whose approach focused on a broader context of health and lived experience. This project drew 30 participants from: Yellowknife, Lutsel 'ke, Behchokö and Ulukhaktok. These four different communities across the NT represented Dene and Inuit culture. The qualitative data analysis offered themes of importance to women's health in the north including: land and tradition; housing; poverty; food; family; health, mental health and trauma, and travel. Photovoice provides a non-threatening way to engage in dialogue on complex health and social issues.

    Information on fish populations, fisheries, and fish habitat is crucial to the success of ongoing program to protect, recover, enhance, and manage fish resources in the Columbia River Basin. However, pertinent data are often difficult to locate because it is scattered among many agencies and is often unpublished. The goal of this annual report is to bring many diverse data types and sources into a single comprehensive report on the status of anadromous fish runs in the Columbia River Basin and the environmental conditions that may affect that status. Brief summaries are provided to identify the type and scope of available information. This synopsis is intended to complement other more detailed reports to which readers are referred for comprehensive treatment of specific subjects. This first report focuses mainly on anadromous salmon and steelhead (primarily through 1994) but the authors intend to expand the scope of future issues to include resident species. This is the first of what the authors intend to be an annual report. They welcome constructive suggestions for improvements. This report is a product of the StreamNet (formerly Coordinated Information System and Northwest Environmental Data Base) project which is a part of the Bonneville Power Administration`s program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric facilities on the Columbia River and its tributaries. The project is called for in the Fish and Wildlife Program of the Northwest Power Planning Council. The project`s objective is to promote exchange and dissemination of information in a standardized electronic format throughout the basin. This project is administered by the Pacific States Marine Fisheries Commission with active participation by tribal, state, and federal fish and wildlife agencies.

    A recent survey for onchocerciasis conducted among the Yanomami Indians living on the middle reaches of the Mucajaí and Catrimâni Rivers (Territory of Roraima) has failed to show any alteration in the local pattern of the disease. In fact, after a decade from the first surveys in these areas located at the periphery of the Yanomami focus, the prevalence and the intensity of infection have not experienced a significant change. Considering only the residents in the villages inside the surveyed areas, the prevalence varied from zero in the neighbourhood of the Catrimâni mission to 3.1 per cent near the Mucajaí mission. Had there been a competent vector of Onchocerca volvulus in the region higher rates might be expected due to the Yanomami custom of periodic visits among the groups of the tribe. In some of these visits, numbers of highly infected Indians from the central and mountainous part of the Yanomami territory--where more than 90 per cent of the adults have onchocerciasis--come to the villages in the lowland area, attracted by the facilities offered by the mission posts. As the visitors stay in the host villages for several days or weeks, the residents could become exposed to the disease. Simulium oyapockense s.1., a man-biting species of black fly, widely distributed in Northern Brazil, is the only possible vector of O. volvulus in the investigated areas, on the grounds of its local abundance.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. The Fort Smith radioactive belt, Northwest Territories

    1980-01-01

    The Fort Smith Belt is an elongate zone, about 200 km x 50 km, extending from the East Arm of Great Slave Lake southerly into northeastern Alberta. The major feature of the belt is that it is one of the most radioactive regions so far recognized in the Canadian Shield. Potassium, uranium, and thorium are all enriched but the greatest increase is in thorium. The dominant rock type underlying the area is a foliated porphyritic granite. This rock contains an average of about 80 ppm thorium (with areas of tens of square kilometres containing up to 200 ppm) and approximately 11 ppm uranium. In places, dark elongate zones rich in biotite, apatite, and opaque minerals within the porphyritic granite may contain an order of magnitude more uranium and thorium than the porphyry. Radioactive minerals within both the porphyry and the dark zones are principally monazite (containing up to 16% ThO 2 ) and isolated grains of uraninite. This foliated porphyritic granite is interpreted as being pre- or syntectonic with respect to the Hudsonian event because its foliation parallels that of the surrounding rocks. There has been subsequent deformation. The second characteristic feature of the Fort Smith Belt is the development of a peripheral zone where eU is enriched relative to eTh correlating mainly with granitoid rocks which surround the thorium-rich area and wherein ratios of eU/eTh exceed 1:2 (compared to the crustal average of 1:4). Uranium may have moved laterally into this marginal area from the thorium-rich porphyry, possibly in a vapour phase. There is a possibility that concentrations of uranium as well as other metals such as Cu, Mo, Zn, Sn, and W could exist in the porphyry and its margin in appropriate chemical and/or structural traps. The radioactive granite rocks of the Fort Smith Belt are adjacent to uranium-thorium occurrences in the nearby Proterozoic Nonacho sediments but whether or not a genetic relationship exists between the two situations is uncertain.

    Full Text Available Remote sensing has considerable potential to contribute to the identification and reconstruction of lost hydrological systems and networks. Remote sensing-based reconstructions of palaeo-river networks have commonly employed single or limited time-span imagery, which limits their capacity to identify features in complex and varied landscape contexts. This paper presents a seasonal multi-temporal approach to the detection of palaeo-rivers over large areas based on long-term vegetation dynamics and spectral decomposition techniques. Twenty-eight years of Landsat 5 data, a total of 1711 multi-spectral images, have been bulk processed using Google Earth Engine© Code Editor and cloud computing infrastructure. The use of multi-temporal data has allowed us to overcome seasonal cultivation patterns and long-term visibility issues related to recent crop selection, extensive irrigation and land-use patterns. The application of this approach on the Sutlej-Yamuna interfluve (northwest India, a core area for the Bronze Age Indus Civilisation, has enabled the reconstruction of an unsuspectedly complex palaeo-river network comprising more than 8000 km of palaeo-channels. It has also enabled the definition of the morphology of these relict courses, which provides insights into the environmental conditions in which they operated. These new data will contribute to a better understanding of the settlement distribution and environmental settings in which this, often considered riverine, civilisation operated.

  12. Assessment of spatial and temporal patterns of green and blue water flows under natural conditions in inland river basins in Northwest China

    2012-08-01

    Full Text Available In arid and semi-arid regions freshwater resources have become scarcer with increasing demands from socio-economic development and population growth. Until recently, water research and management has mainly focused on blue water but ignored green water. Furthermore, in data poor regions hydrological flows under natural conditions are poorly characterised but are a prerequisite to inform future water resources management. Here we report on spatial and temporal patterns of both blue and green water flows that can be expected under natural conditions as simulated by the Soil and Water Assessment Tool (SWAT for the Heihe river basin, the second largest inland river basin in Northwest China. Calibration and validation at two hydrological stations show good performance of the SWAT model in modelling hydrological processes. The total green and blue water flows were 22.05–25.51 billion m3 in the 2000s for the Heihe river basin. Blue water flows are larger in upstream sub-basins than in downstream sub-basins mainly due to high precipitation and a large amount of snow and melting water in upstream. Green water flows are distributed more homogeneously among different sub-basins. The green water coefficient was 87%–89% in the 2000s for the entire river basin, varying from around 80%–90% in up- and mid-stream sub-basins to above 90% in downstream sub-basins. This is much higher than reported green water coefficients in many other river basins. The spatial patterns of green water coefficients were closely linked to dominant land covers (e.g. snow cover upstream and desert downstream and climate conditions (e.g. high precipitation upstream and low precipitation downstream. There are no clear consistent historical trends of change in green and blue water flows and the green water coefficient at both the river basin and sub-basin levels. This study provides insights into green and blue water endowments under natural conditions for the entire

  13. Mining pollution and the diet of the purple-striped Gudgeon Mogurnda Mogurnda Richardson (Eleotridae) in the Finniss River, Northern Territory, Australia

    1980-01-01

    During the dry season of 1974, collections of the purple-striped Gudgeon Mogurnda Mogurnda were taken from the Finniss River of the Northern Territory; during the wet season, this river receives acidic and metallic pollutants from the formerly mined area of Rum Jungle. The fish consumed a great variety of foods, with high abundances of dytiscidae, chironomidae, ceratopogonidae, trichoptera, odonata, copepoda, decapoda, and pisces. For no food was there a significant regression against habitat descriptors in both of the zones; this emphasizes that pollution effects are more complex than simply depressing or raising the abundances of the dietary species. Five foods were more abundant in the diets of the polluted zone, and three in those of the unpolluted zone. The dietary abundances of two foods, both crustacean, increased in the polluted zone, compared to the unpolluted zone, through the dry season. Two categories of foods: (1) those obtaining oxygen directly from the atmosphere or via a film or bubble of air; and (2) the converse set (aquatic respirers), were contrasted for their usefulness in distinguishing between the zones, by both hierarchical agglomerative and discriminant function analyses. One collection from the polluted zone was reclassified as unpolluted on the basis of its grouping behaviour. The relevance for pollution studies of dietary analysis of euryphagous fish, rather than sampling aquatic fauna directly, is discussed in terms of food substitution, switching, strategies for abundance and recovery by the fauna, and possible effects of the pollutants on the fish as an intervening collector. Downstream patterns of abundance of the invertebrate fauna in this study are broadly similar to those of other studies in which such chemically diverse metals as Pb, Zn, and Cu are the pollutants, but there are differences for some faunal components.

    Full text: Intensive and insufficiently controlled human industrial activities, ignoring regional geological and geochemical processes, resulted in considerable chemical pollution and radioactive contamination of these river's basins, where some large nuclear power plants, uranium and chemical enterprises, oil and gas productions are also located. This epidemiological and environmental situation aggravated further after USSR collapse and the establishment of new independent states due to lack of the appropriate environmental monitoring in those countries and on their near-border areas in particular, that contributed to further aggravation of the political tension and economic destabilization between transboundary countries. The environmental situation here is one of most unfavorable among world water ecosystems. In recent years different pollutants (radionuclides, toxins, organic substances and heavy metals) activate reduction processes in bottom sediments, that lead to changes in sulfur and carbon cycles, the oxygen deficit in water, to eutrophication of water reservoirs and their biological degradation. Today the development of total environmental monitoring systems is clearly necessary for operative current control, ensuring preparedness and prediction of any potential emergencies of global and local scales and their long-term effects. The objectives for presented monitoring systems are to: (1)study sources and mechanisms of chemical pollution and radioactive contamination of water basins of Volga (the largest river in Europe and Russia), Terek and Ural rivers flowed into Caspian Sea, and Ob, Irtysh and Tom ones, flowed into Kara Sea in Arctic Ocean within RF territory; (2) develop the well-ground database (DB) on contamination; (3) the using of the obtained results for the operative current trans boundary control, monitoring and protection of freshwater resources; (4) modeling of pollutant's migration. There is no way to provide solution of environmental

    Appropriate geochemical analogues may be used to reduce the uncertainties in predicting the long-term transport of actinides, radium and fission products from laboratory adsorption and hydrological data. In this study the migration of uranium series nuclides within, and down-gradient of ore bodies in the Alligator Rivers uranium province of the Northern Territory of Australia is described. A mathematical framework was developed to permit calculation of the rate of leaching or deposition of uranium and radium between defined zones of the ore bodies, and the rate of loss of the nuclides due to groundwater transport and surface erosion. A detailed study was made of the distribution of uranium, thorium and radium isotopes within various minerals comprising the weathered ore assemblage. Uranium and thorium concentrate principally in the iron minerals and radium in the clay-quartz phases. Substantial disequilibria are observed, which are attributed to a combination of α-recoil and chemical effects. Evidence of the relative lability of iron phases is presented. The transport of uranium series nuclides in groundwater intersecting the deposits was investigated. Down-gradient of the Ranger One deposit, the maximum retardation factor of uranium is 250. The role of colloids in groundwater transport is being studied. Uranium is transported principally in solution. There appears to be an equilibrium between solute and articulate uranium

    The existing uranium mines in the Alligator River Region presently operate under a no release water management regime for water stored within the designated restricted release zones (RRZ). This water is of variable quality ranging from rainwater influenced by runoff from the mill sites and ore stockpiles to mill process water stored within the trailings repositories. There is a pressing need to reduce the volume of stored RRZ water at Nabarlek as a prerequisite to decommissioning. There is also a requirement at Ranger to rapidly reduce the volume of stored water in the mine pit at the end of the season to allow the mining of ore. Land application of RRZ water by spray irrigation has been investigated at both sites because it offers the benefits of applying chemical constituents in the wastewater within a clearly defined irrigation area. the environmental planning for the design of a land application system involves calculations of the chemical load in the wastewater and evaluation of the assimilative capacity of the soil-plant system. The monsoon climate, lateritic soil and fluctuating water table creates a unique set of environmental constraints and conditions in which to design and operate a successful land application system for the treatment of stored water at minesites within ecologically sensitive areas

    Milling of uraniferous and other metalliferous ores at the Northern Hercules (Moline) Mine near Pine Creek produced some 246,000 tonnes of tailings between 1959 and the closure of the mill in 1972. During this period tailings were contained by several bunds which later failed resulting in the erosion and transport of tailings by tributaries of the Mary River. Suspended sediment concentrations as high as 94 g/L were recorded in Tailings Creek immediately downstream of the eroding tailings pile during the 1984/85 wet season and the total yield was equivalent to a mean erosion rate for the tailings area of 4 mm/yr. This erosion rate is about two orders of magnitude higher than natural rates in the Pine Creek area. Erosion rates of the tailings pile have, however, decreased perhaps by as much as a factor of eight since the last bund was breached. Radioactive dose rates recorded along a series of transects across floodplains downstream of the mill are consistently related to the sedimentary environment. The main channel is associated with low dose rates, and the relatively low energy environments of backswamps and flood bypass channels are characterised by higher dose rates. Longitudinally, dose rates on the floodplain generally decrease with distance downstream although the rate of decrease is not constant, and appears to be dependent upon the hydrological and geomorphic character of the catchment

    Gravel-dominated strata, inter-bedded with, and overlying coal-bearing units, are interpreted as deposits of wandering gravel-bed rivers, with sinuosity approaching 1.4. In most exposures they appear to be dominated by massive and thin planar-bedded granule to small pebble conglomerates, which would traditionally be interpreted as sheet-flood or longitudinal bar deposits of a high-gradient braided stream or alluvial fan. Architectural analysis of exposures in an open-pit shows that the predominance of flat bedding is an artefact of the geometry of the roadside exposures. In the pit the conglomerates are dominated by large scale cross stratification on a scale of 1–5.5 m. These appear to have developed as downstream and lateral accretion elements on side-bars and on in-channel bars in water depths of 2–12 m. Stacking of strata on domed 3rd order surfaces suggests development of longitudinal in-channel bar complexes similar to those observed in parts of the modern Rhône River system. Mudstone preserved in some of the channels reflects intervals of channel abandonment or avulsion. Minimum channel width is from 70 to 450 m.

    Full Text Available Carbon management in forests has become the most important agenda of the first half of the 21st century in China in the context of the mitigation of climate change impact. As the main producer of the inland river basin ecosystem in arid region of Northwest China, the desert riparian forest maintains the regional environment and also holds a great significance in regulating the regional/global carbon cycle. In this study, we estimated the total biomass, carbon storage, as well as monetary ecosystem service values of desert riparian Populus euphratica Oliv. in the lower reaches of the Tarim River based on terrestrial forest inventory data within an area of 100 ha (100 plots with sizes of 100 m × 100 m and digitized tree data within 1000 ha (with 10 m × 10 m grid using a statistical model of biomass estimation against tree height (TH and diameter at breast height (DBH data. Our results show that total estimated biomass and carbon storage of P. euphratica within the investigated area ranged from 3.00 to 4317.00 kg/ha and from 1.82 to 2158.73 kg/ha, respectively. There was a significant negative relationship (p < 0.001 between biomass productivity of these forests and distance to the river and groundwater level. Large proportions of biomass (64% of total biomass are estimated within 200 m distance to the river where groundwater is relatively favorable for vegetation growth and biomass production. However, our data demonstrated that total biomass showed a sharp decreasing trend with increasing distance to the river; above 800 m distance, less biomass and carbon storage were estimated. The total monetary value of the ecosystem service “carbon storage” provided by P. euphratica was estimated to be $6.8 × 104 USD within the investigated area, while the average monetary value was approximately $70 USD per ha, suggesting that the riparian forest ecosystem in the Tarim River Basin should be considered a relevant regional carbon sink.

    Much attention has recently been focused on the effects that climate variability and human activities have had on runoff. In this study, data from the Kaidu River Basin in the arid region of northwest China were analyzed to investigate changes in annual runoff during the period of 1960-2009. The nonparametric Mann-Kendall test and the Mann-Kendall-Sneyers test were used to identify trend and step change point in the annual runoff. It was found that the basin had a significant increasing trend in annual runoff. Step change point in annual runoff was identified in the basin, which occurred in the year around 1993 dividing the long-term runoff series into a natural period (1960-1993) and a human-induced period (1994-2009). Then, the hydrologic sensitivity analysis method was employed to evaluate the effects of climate variability and human activities on mean annual runoff for the human-induced period based on precipitation and potential evapotranspiration. In 1994-2009, climate variability was the main factor that increased runoff with contribution of 90.5 %, while the increasing percentage due to human activities only accounted for 9.5 %, showing that runoff in the Kaidu River Basin is more sensitive to climate variability than human activities. This study quantitatively distinguishes the effects between climate variability and human activities on runoff, which can do duty for a reference for regional water resources assessment and management.

    Full Text Available This study evaluated hydrological impacts of potential climate and land use changes in Heihe River Basin of Northwest China. The future climate data for the simulation with Soil and Water Assessment Tool (SWAT were prepared using a dynamical downscaling method. The future land uses were simulated with the Dynamic Land Use System (DLS model by establishing Multinomial Logistic Regression (MNL model for six land use types. In 2006–2030, land uses in the basin will experience a significant change with a prominent increase in urban areas, a moderate increase in grassland, and a great decrease in unused land. Besides, the simulation results showed that in comparison to those during 1981–2005 the temperature and precipitation during 2006–2030 will change by +0.8°C and +10.8%, respectively. The land use change and climate change will jointly make the water yield change by +8.5%, while they will separately make the water yield change by −1.8% and +9.8%, respectively. The predicted large increase in future precipitation and the corresponding decrease in unused land will have substantial impacts on the watershed hydrology, especially on the surface runoff and streamflow. Therefore, to mitigate negative hydrological impacts and utilize positive impacts, both land use and climate changes should be considered in water resource planning for the Heihe River Basin.

    Based on the data for meteorology, hydrology, soil, planting, vegetation, and socio-economic development of the irrigation region in the middle reaches of the Heihe River basin, Northwest China, the model of balance of water supply and demand in the region was established, and the security of water resource was assessed, from which the results that the effects of unified management of water resources in the Heihe River basin between Gansu Province and Inner Mongolia on regional hydrology are significant with a decrease in water supply diverted from Heihe River and an increase in groundwater extracted. In addition, it was found that the groundwater level has been steadily decreasing due to over pumping and decrease in recharges. In present year (2003), the volume of potential groundwater in the irrigation districts is far small because of the groundwater overdraft; even in the particular regions, there is no availability of groundwater resources for use. By 2003, water supply is not sufficient to meet the water demand in the different irrigation districts, the sustainable development and utilization of water resources are not secured, and the water supply crisis occurs in Pingchuan irrigation district. Achieving water security for the sustainable development of society, agriculture, economy, industry, and livelihoods while maintaining or improving the abilities of the management and planning of water resources, determining of the reasonable percentage between water supply and groundwater utilization and water saving in agricultural irrigation are taken into account. If this does not occur, it is feared that the present performance of water development and planning may further aggravate the problem of scarcities of water resources and further damage the fragile ecological system.

    The Tarim River basin, located in Xinjiang, NW China, is the largest endorheic river basin in China and one of the largest in all of Central Asia. Due to the extremely arid climate, with an annual precipitation of less than 100 mm, the water supply along the Aksu and Tarim rivers solely depends on river water. This is linked to anthropogenic activities (e.g., agriculture) and natural and semi-natural ecosystems as both compete for water. The ongoing increase in water consumption by agriculture and other human activities in this region has been enhancing the competition for water between human needs and nature. Against this background, 11 German and 6 Chinese universities and research institutes have formed the consortium SuMaRiO (Sustainable Management of River Oases along the Tarim River; de"target="_blank">http://www.sumario.de), which aims to create a holistic picture of the availability of water resources in the Tarim River basin and the impacts on anthropogenic activities and natural ecosystems caused by the water distribution within the Tarim River basin. On the basis of the results from field studies and modeling approaches as well as from suggestions by the relevant regional stakeholders, a decision support tool (DST) will be implemented that will then assist stakeholders in balancing the competition for water, acknowledging the major external effects of water allocation to agriculture and to natural ecosystems. This consortium was formed in 2011 and is funded by the German Federal Ministry of Education and Research. As the data collection phase was finished this year, the paper presented here brings together the results from the fields from the disciplines of climate modeling, cryology, hydrology, agricultural sciences, ecology, geoinformatics, and social sciences in order to present a comprehensive picture of the effects of different water availability schemes on anthropogenic activities and natural ecosystems along the Tarim River.

    Land Use/Land Cover Change (LUCC) is the core components of global change researches. It is significant for understanding regional ecological environment and LUCC mechanism of large scale to develop the study of LUCC of regional level. Nujiang River is the upper reaches of a big river in the South Asia--Salween River. Nujiang River is a typical mountainous river which is 3200 kilometer long and its basin area is 32.5 × 105 square kilometer. It locates in the core of "Three Parallel Rivers" World Natural Heritage. It is one of international biodiversity conservation center of the world, the ecological fragile zone and key ecological construction area, as well as a remote undeveloped area with high diversity ethnic. With the rapidly development of society and economy, the land use and land cover changed in a great degree. The function of ecosystem has being degraded in some areas which will not only impact on the ecological construction of local area, but also on the ecological safety of lower reaches -- Salween River. Therefore it is necessary to carry out the research of LUCC of Nujiang River. Based on the theory and methods of geo-information Tupu, the "Spatial Pattern" and "Change Process" of land use of middle reach in Nujiang River from 1974 to 2004 had been studied in quantification and integration, so as to provide a case study in local area and mesoscale in time. Supported by the remote sensing and GIS technology, LUCC Tupu of 1974-2004 had been built and the characteristics of LUCC have been analyzed quantificationally. The results showed that the built-up land (Included in this category are cities, towns, villages, strip developments along highways, transportation, power, and communications facilities, and areas such as those occupied by mills, shopping centers, industrial and commercial complexes, and institutions that may, in some instances, be isolated from urban areas), agriculture land, shrubbery land, meadow & grassland, difficultly/unused land

    Reactor fuel failure data sets in the form of initial power (P/sub i/), final power (P/sub f/), transient increase in power (ΔP), and burnup (Bu) were obtained for pressurized heavy water reactors (PHWRs), boiling water reactors (BWRs), and pressurized water reactors (PWRs). These data sets were evaluated and used as the basis for developing two predictive fuel failure models, a graphical concept called the PCI-OGRAM, and a nonlinear regression based model called PROFIT. The PCI-OGRAM is an extension of the FUELOGRAM developed by AECL. It is based on a critical threshold concept for stress dependent stress corrosion cracking. The PROFIT model, developed at Pacific Northwest Laboratory, is the result of applying standard statistical regression methods to the available PCI fuel failure data and an analysis of the environmental and strain rate dependent stress-strain properties of the Zircaloy cladding

    The current study focused on the Bortala River - a typical inland river located in an oasis of arid area in northwestern China. The sediment and soil samples were collected from the river and drainage basin. Results showed that: (1) the particle size of the sand fraction of the sediments was 78-697 µm, accounting for 78.82% of the total samples; the average concentrations of eight heavy metals fell within the concentration ranges recommended by the Secondary National Standard of China, while the maximum concentrations of Pb, Cd, and Hg exceeded these standards; (2) results from multivariate statistical analysis indicated that Cu, Ni, As, and Zn originated primarily from natural geological background, while Cd, Pb, Hg and Cr in the sediments originated from human activities; (3) results of the enrichment factor analysis and the geo-accumulation index evaluation showed that Cd, Hg, and Pb were present in the surface sediments of the river at low or partial serious pollution levels, while Zn, Cr, As, Ni, and Cu existed at zero or low pollution levels; (4) calculation of the potential ecological hazards index showed that among the eight tested heavy metals, Cd, Pb, Hg, and Cr were the main potential ecological risk factors, with relative contributions of 25.43%, 22.23%, 21.16%, and 14.87%, respectively; (5) the spatial distribution of the enrichment factors (EF(S)), the Geo-accumulation index (I(geo)), and the potential ecological risk coefficient (E(r)(i)) for eight heavy metals showed that there was a greater accumulation of heavy metals Pb, Cd, and Hg in the sediments of the central and eastern parts of the river. Results of this research can be a reference for the heavy metals pollution prevention, the harmony development of the ecology protection and the economy development of the oases of inland river basin of arid regions of China, Central Asia and also other parts of the world.

    Unglaciated parts of the Yukon constitute one of the most important areas in North America for yielding Pleistocene vertebrate fossils. Nearly 30 vertebrate faunal localities are reviewed spanning a period of about 1.6 Ma (million years ago) to the close of the Pleistocene some 10 000 BP (radiocarbon years before present, taken as 1950). The vertebrate fossils represent at least 8 species of fishes, 1 amphibian, 41 species of birds and 83 species of mammals. Dominant among the large mammals are: steppe bison ( Bison priscus), horse ( Equus sp.), woolly mammoth ( Mammuthus primigenius), and caribou ( Rangifer tarandus) - signature species of the Mammoth Steppe fauna ( Fig. 1), which was widespread from the British Isles, through northern Europe, and Siberia to Alaska, Yukon and adjacent Northwest Territories. The Yukon faunas extend from Herschel Island in the north to Revenue Creek in the south and from the Alaskan border in the west to Ketza River in the east. The Yukon holds evidence of the earliest-known people in North America. Artifacts made from bison, mammoth and caribou bones from Bluefish Caves, Old Crow Basin and Dawson City areas show that people had a substantial knowledge of making and using bone tools at least by 25 000 BP, and possibly as early as 40 000 BP. A suggested chronological sequence of Yukon Pleistocene vertebrates ( Table 1) facilitates comparison of selected faunas and indicates the known duration of various taxa.

    Snowmelt water is an important freshwater resource in the Altay Mountains in northwest China, and it is also crucial for local ecological system, economic and social sustainable development; however, warming climate and rapid spring snowmelt can cause floods that endanger both eco-environment and public and personal property and safety. This study simulates snowmelt in the Kayiertesi River catchment using a temperature-index model based on remote sensing coupled with high-resolution meteorological data obtained from NCEP reanalysis fields that were downscaled using Weather Research Forecasting model, then bias-corrected using a statistical downscaled model. Validation of the forcing data revealed that the high-resolution meteorological fields derived from downscaled NCEP reanalysis were reliable for driving the snowmelt model. Parameters of temperature-index model based on remote sensing were calibrated for spring 2014, and model performance was validated using MODIS snow cover and snow observations from spring 2012. The results show that the temperature-index model based on remote sensing performed well, with a simulation mean relative error of 6.7% and a Nash-Sutchliffe efficiency of 0.98 in spring 2012 in the river of Altay Mountains. Based on the reliable distributed snow water equivalent simulation, daily snowmelt runoff was calculated for spring 2012 in the basin. In the study catchment, spring snowmelt runoff accounts for 72% of spring runoff and 21% of annual runoff. Snowmelt is the main source of runoff for the catchment and should be managed and utilized effectively. The results provide a basis for snowmelt runoff predictions, so as to prevent snowmelt-induced floods, and also provide a generalizable approach that can be applied to other remote locations where high-density, long-term observational data is lacking.

    Based on the field observation on the Tamarix ramosissima populations in the lower reaches of Heihe River, the relationship models between the aboveground biomass of T. ramosissima and its morphological features (basal diameter, height, and canopy perimeter) were built. In the mean time, the land use/cover of the study area was classified by the decision tree classification with high resolution image (QuickBird), the distribution of T. ramosissima was extracted from classification map, and the morphological feature (canopy perimeter) of T. ramosissima was calculated with ArcGIS 9.2. On the bases of these, the spatial distribution of T. ramosissima aboveground biomass in the study area was estimated. Finally, the spatial distribution of the water consumption of T. ramosissima in the study area was calculated by the transpiration coefficient (300) and the aboveground biomass. The results showed that the aboveground biomass of T. ramosissima was 69644.7 t, and the biomass per unit area was 0.78 kg x m(-2). Spatially, the habitats along the banks of Heihe River were suitable for T. ramosissima, and thus, this tree species had a high biomass. The total amount of water consumption of T. ramosissima in the study area was 2.1 x 10(7) m3, and the annual mean water consumption of T. ramosissima ranged from 30 mm to 386 mm.

    This article selected zonal plant communities as the research objects in different vegetation zones in Yanhe River basin. We measured six leaf traits of the dominant species and main accompanying species in each community, and then analyzed the relationships and their changes along with environmental gradients between these traits in order to understand the plant adaptation strategies to the environment changes. The results showed that the specific leaf area was significantly negatively correlated to leaf tissue density, area-based leaf nitrogen and phosphorus concentrations, and significantly positively correlated to mass-based leaf phosphorus concentration. Both the scaling relationships among these traits and plant life strategies were different among the three vegetation zones, the scaling-dependent relationship between leaf tissue density and specific leaf area was stronger in steppe and forest-steppe zones than in forest zone, but the correlations among area-based leaf nitrogen/phosphorus concentrations and specific leaf area and leaf tissue density were more significant in forest zone than in steppe zone. In the arid grassland and forest-steppe zone, plants give priority to defensive and stress resistance strategies, and in relatively moist nutrient-rich forest zone, plants give priority to fast growth and resource optimization allocation strategies.

    Full Text Available The General Urban Plan represents the legal ground for any development action proposed. After endorsement and approval as required by law, GUP is act of authority of local government for the area in which it applies. The aim is to establish priorities regulations applied in land use planning and construction of structures. In terms of geographical location, the administrative territory of Casimcea, Tulcea county, falls in the central Northwest Plateau Casimcei. This is the second unit of the Central Dobrogea Plateau. Geographical location in southeastern Romania, climatic and relief conditions and anthropogenic pressure, expose the village administrative territorial unit Casimcea, permanent susceptibility to produce natural and antropogenical risks. In this context, we identified the following categories of natural and anthropogenic risks: i natural risk phenomena (earthquakes, strong winds, heavy rains, floods caused by overflowing or precipitation, erosion of river banks and torrents, gravitational processes, rain droplet erosion and surface soil erosion; and ii anthropogenic risk phenomena (overgrazing, chemicals use in agriculture, road transport infrastructure and electricity, wind turbines for electricity production, waste deposits, agro-zootechnical complexs, and human cemeteries. Extending their surface was materialized by creating a map of natural and anthropogenic risk on Casimcea territorial administrative unit, explaining the share of potentially affected areas as territorial balance

    The community of climate change impact assessments and adaptations research needs regional high-resolution (spatial) meteorological data. This study produced two downscaled precipitation datasets with spatial resolutions of as high as 3 km by 3 km for the Heihe River Basin (HRB) from 2011 to 2014 using the Weather Research and Forecast (WRF) model nested with Final Analysis (FNL) from the National Center for Environmental Prediction (NCEP) and ERA-Interim from the European Centre for Medium-Range Weather Forecasts (ECMWF) (hereafter referred to as FNLexp and ERAexp, respectively). Both of the downscaling simulations generally reproduced the observed spatial patterns of precipitation. However, users should keep in mind that the two downscaled datasets are not exactly the same in terms of observations. In comparison to the remote sensing-based estimation, the FNLexp produced a bias of heavy precipitation centers. In comparison to the ground gauge-based measurements, for the warm season (May to September), the ERAexp produced more precipitation (root-mean-square error (RMSE) = 295.4 mm, across the 43 sites) and more heavy rainfall days, while the FNLexp produced less precipitation (RMSE = 115.6 mm) and less heavy rainfall days. Both the ERAexp and FNLexp produced considerably more precipitation for the cold season (October to April) with RMSE values of 119.5 and 32.2 mm, respectively, and more heavy precipitation days. Along with simulating a higher number of heavy precipitation days, both the FNLexp and ERAexp also simulated stronger extreme precipitation. Sensitivity experiments show that the bias of these simulations is much more sensitive to micro-physical parameterizations than to the spatial resolution of topography data. For the HRB, application of the WSM3 scheme may improve the performance of the WRF model.

  20. Mapping Daily Evapotranspiration based on Spatiotemporal Fusion of ASTER and MODIS Images over Irrigated Agricultural Areas in the Heihe River Basin, Northwest China

    Continuous monitoring of daily evapotranspiration (ET) is crucial for allocating and managing water resources in irrigated agricultural areas in arid regions. In this study, continuous daily ET at a 90-m spatial resolution was estimated using the Surface Energy Balance System (SEBS) by fusing Moderate Resolution Imaging Spectroradiometer (MODIS) images with high temporal resolution and Advanced Space-borne Thermal Emission Reflectance Radiometer (ASTER) images with high spatial resolution. The spatiotemporal characteristics of these sensors were obtained using the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM). The performance of this approach was validated over a heterogeneous oasis-desert region covered by cropland, residential, woodland, water, Gobi desert, sandy desert, desert steppe, and wetland areas using in situ observations from automatic meteorological systems (AMS) and eddy covariance (EC) systems in the middle reaches of the Heihe River Basin in Northwest China. The error introduced during the data fusion process based on STARFM is within an acceptable range for predicted LST at a 90-m spatial resolution. The surface energy fluxes estimated using SEBS based on predicted remotely sensed data that combined the spatiotemporal characteristics of MODIS and ASTER agree well with the surface energy fluxes observed using EC systems for all land cover types, especially for vegetated area with MAP values range from 9% to 15%, which are less than the uncertainty (18%) of the observed in this study area. Time series of daily ET modelled from SEBS were compared to that modelled from PT-JPL (one of Satellite-based Priestley-Taylor ET model) and observations from EC systems. SEBS performed generally better than PT-JPL for vegetated area, especially irrigated cropland with bias, RMSE, and MAP values of 0.29 mm/d, 0.75 mm/d, 13% at maize site, -0.33 mm/d, 0.81 mm/d, and 14% at vegetable sites.

    Two freshwater bathing sites, the Crook O'Lune and the University Boathouse, on the River Lune in the north-west of England, were monitored over a 2 year period for the faecal indicators, faecal coliforms and faecal streptococci, the pathogens, Salmonella and Campylobacter, and compliance with the EU Directive on Bathing Water Quality. Faecal indicator numbers showed no seasonal variation, with numbers in the bathing season similar to those in the non-bathing season. They were consistently above the EU Guideline and Imperative standards so that if the EU Bathing Water Quality Directive (76/160/EEC) were applied, neither site would comply. Faecal indicator numbers in the sediments were an order of magnitude higher than in the overlying water. Campylobacter numbers showed seasonal variation in the water with higher counts in winter than in the summer, although numbers were low. Higher numbers were found in the sediments but there was no seasonal variation. Analysis of various inputs showed that indicators and campylobacters came from a mixture of sources, namely a sewage treatment works, agricultural run-off, streams and mallards. Microbial numbers in the water at the Crook O'Lune, which is closer to the sources of pollution, were twice those at the Boathouse. In the sediments they were six to eight times higher. Faecal coliforms were all identified as Escherichia coli of which 80% were a single biotype. Faecal streptococci were all enterococci of which 55% were E. avium, 38% E. faecalis and 7% E. durans. Salmonella was not isolated from either the water column or the sediments. Campylobacters were mainly Camp. jejuni, followed by Camp. coli, UPTC and Camp. lari.

    Full Text Available Stability and accident-free operation of engineering road structures including bridge transitions and pipe passages built on mountain rivers mostly depends on a stream regime and lack of obstructions for water flow. Such structures pose a prominent potential hazard being built in piedmont areas of Caucasus Mountains characterized by flash floods and blockage of structures by floating debris, mudflow deposits and wastes of construction. This notwithstanding, the threats caused by these phenomena are poorly studied. The purpose of this study is in estimation of throughput of bridge transitions and pipe passages built on minor rivers of piedmont areas and analysis of hazards caused by floods and obstructions to water flow. The results of calculation of capacities of existing road structures are provided herein. A qualitative assessment of potential emergencies in case of severe flood is also given. A major hazard of possible blockage of waterways that can cause emergency even in regular flood conditions is noted.

    Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temporal variations and the latent sources of water pollution in the Shanchong River basin, Northwest Basin of Lake Fuxian, China. We group all field surveys into 2 clusters (dry season and rainy season). Moreover, 14 sampling sites have been grouped into 3 clusters for the rainy season (highly polluted, moderately polluted and less polluted sites) and 2 clusters for the dry season (highly polluted and less polluted sites) based on their similarities and the level of pollution during the two seasons. The results show that the main trend of pollution was aggravated during the transition from the dry to the rainy season. The Water Pollution Index of Total Nitrogen is the highest of all pollution parameters, whereas the Chemical Oxygen Demand (Chromium) is the lowest. Our results also show that the main sources of pollution are farming activities alongside the Shanchong River, soil erosion and fish culture at Shanchong River reservoir area and domestic sewage from scattered rural residential area. Our results suggest that strategies to prevent water pollutionat the Shanchong River basin need to focus on non-point pollution control by employing appropriate fertilizer formulas in farming, and take the measures of soil and water conservation at Shanchong reservoir area, and purifying sewage from scattered villages.

    The Yampa River in northwestern Colorado is the largest, relatively unregulated river system in the upper Colorado River Basin. Water from the Yampa River Basin continues to be sought for a number of municipal, industrial, and energy uses. It is anticipated that future water development within the Yampa River Basin above the amount of water development identified under the Upper Colorado River Endangered Fish Recovery Implementation Program and the Programmatic Biological Opinion may require additional analysis in order to understand the effects on habitat and river function. Water development in the Yampa River Basin could alter the streamflow regime and, consequently, could lead to changes in the transport and storage of sediment in the Yampa River at Deerlodge Park. These changes could affect the physical form of the reach and may impact aquatic and riparian habitat in and downstream from Deerlodge Park. The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, began a study in 2011 to characterize the current hydrodynamic and sediment-transport conditions for a 2-kilometer reach of the Yampa River in Deerlodge Park. Characterization of channel conditions in the Deerlodge Park reach was completed through topographic surveying, grain-size analysis of streambed sediment, and characterization of streamflow properties. This characterization provides (1) a basis for comparisons of current stream functions (channel geometry, sediment transport, and stream hydraulics) to future conditions and (2) a dataset that can be used to assess channel response to streamflow alteration scenarios indicated from computer modeling of streamflow and sediment-transport conditions.

    Exploration and development of mineral deposits in the Transurals of the Republic of Bashkortostan are accompanied by a comprehensive environmental impact. Ones of the most vulnerable elements of the landscape are the surface water bodies used for fishery purposes, recreation and household needs of the population. Extraction and processing of ores lead to the contamination of aquatic ecosystems by heavy metals (HM), which by passing into a pond, can actively be involved in the cycling of matter and migrate via food chains to the human under the consumption of fish products. Possessing by cumulative properties, HM can express mutagenic, teratogenic and carcinogenic properties. The aim of research was the study of the impact of mining facilities on the content of the priority HM in the components of river ecosystems in the Transurals of the Republic of Bashkortostan and the development of a complex of preventive measures on the improvement of the human environment. There was studied the content of Zn, Cu and Cd in the water, bottom sediments and phytomass of Elodea canadensis Michx. The measurements of mass concentrations of metals were performed by stripping voltammetry with the use of the STA device. The results showed that for the cross-sections there is typical the following descending series of elements in the river components: Zn > Cu > Cd. In water samples there is observed the exceedance of standards for water bodies of potable, cultural and community water use and fishery basins. The concentration of zinc varies in the range of 0.016-5.24 mg/dm; copper - 0.0024-0.095 mg/dm; cadmium - 0.0001-0.019 mg/dm. In bottom sediments, in general, the content of metals in comparison with control plots is increased to the tenfold value. The meaning of mobile forms of zinc in the ground varies in the range of 0.81-9.62 mg/kg; copper - 0.12-18.69 mg/kg; cadmium - 0.00013-0.092 mg/kg.

    Variability at 20 microsatellite loci was examined to assess the population genetic structure, gene flow, and effective population size (N(e)) in three populations of three-spined stickleback (Gasterosteus aculeatus) from the upper basin of the Miño River in Galicia, NW Spain, where this species is threatened. The three populations showed similar levels of genetic diversity. There is a significant genetic differentiation between the three populations, but also significant gene flow. N(e) estimates based on linkage disequilibrium yielded values of 355 for the Miño River population and 241 and 311 for the Rato and Guisande Rivers, respectively, although we expect that these are overestimates. N(e) estimates based on temporal methods, considering gene flow or not, for the tributaries yielded values of 30-56 and 47-56 for the Rato and Guisande Rivers, respectively. Estimated census size (N(c)) for the Rato River was 880 individuals. This yielded a N(e)/N(c) estimate of 3-6 % for temporal estimation of N(e), which is within the empirical range observed in freshwater fishes. We suggest that the three populations analyzed have a sufficient level of genetic diversity with some genetic structure. Additionally, the absence of physical barriers suggests that conservation efforts and monitoring should focus in the whole basin as a unit.

    This study aimed at assessing the stresses from land development in or around Yellow River Delta Nature Reserve (YRDNR) and identifying the impacted areas. Major land development types (reservoirs, pond, aquafarm, salt pan, road, residential land, industry land, farming land, and fishing land) in or around the YRDNR from 1995 to 2014 were identified using spatial data sets derived from remote sensing imageries. The spatial stresses were simulated by considering disturbance due to land development activities and accessibility of disturbance using a geographic information system based model. The stresses were then used to identify the impacted area by land development (IALD). The results indicated that main increasing land development types in the study area from 1995 to 2014 were salt pan and construction land. The 98.2% of expanded land development area and 93.7% of increased pump number showed a good control of reserve function zone on land development spread. The spatial stress values and percentages of IALD increased from 1995 to 2014, and IALD percentage exceeded 50% for both parts of YRDNR in 2014. The results of this study also provided the information that detailed planning of the YRDNR (2014-2020) could decrease the spatial stress and IALD percentage of the whole YRDNR on the condition that the area of land development activities increased by 24.4 km 2 from 2014 to 2020. Effective measures should be taken to protect such areas from being further disturbed in order to achieve the goal of a more effective conservation of the YRDNR, and attention should be paid to the disordered land development activities in or around the natural reserves.

    Tessa River is seen as one of the important rivers in Tunisia. Its catchment is known for its agricultural and mining activities, especially the Bougrine and Fedj Lahdhoum mines. Eighteen (18) surface sediments and five (5) water samples were collected from the Tessa River, near these two mining sites. Sediments are essentially sandy (>80%), the most important mineral is quartz (20-73%), then calcite (41%) and dolomites (4%). Heavy metal contents are relatively high near the mining sites, 356 μg g-1 for Pb, 3000 μg g-1 for Zn, and 5 μg g-1 for Cd. These values are lower downstream due to watercourse dilution effects. Other heavy metals: Cu, Ni and Cr, are low, and values are relatively constant in all the studied samples, even near the mining sites. The metals originate from natural sources and not from mining activities. This trend is confirmed by the enrichment factor (EF) where EFNi, EFCu and EFCr are lower or equal to 1, unlike EFPb, EFZn or EFCd where values are much higher (>20). Chemical speciation of these metals does not show any spatial variation. Except for cadmium which is bound to the residual fraction and in the carbonates; all other heavy metals are bound to the five sediment chemical fractions: the residual fraction (>52%), followed by the oxyhydroxides fraction (21%) and carbonates (16%), and finally bound to the organic matter and to the exchangeable fraction (bioavailable fraction of the studied heavy metals exceeds 45%, which present risk of toxicity.

    Knowledge of the spatial-temporal variability of soil water content (SWC) is critical for understanding a range of hydrological processes. In this study, the spatial variance and temporal stability of SWC were investigated in a cropland-shelterbelt-desert site at the oasis-desert ecotone in the middle of the Heihe River Basin, China. The SWC was measured on 65 occasions to a depth of 2.8 m at 45 locations during two growing seasons from 2012 to 2013. The standard deviation of the SWC versus the mean SWC exhibited a convex upward relationship in the shelterbelt with the greatest spatial variation at the SWC of around 22.0%, whereas a linearly increasing relationship was observed for the cropland, desert, and land use pattern. The standard deviation of the relative difference was positively linearly correlated with the SWC (p < 0.05) for the land use pattern, whereas such a relationship was not found in the three land use types. The spatial pattern of the SWC was more time stable for the land use pattern, followed by desert, shelterbelt, and cropland. The spatial pattern of SWC changed dramatically among different soil layers. The locations representing the mean SWC varied with the depth, and no location could represent the whole soil profile due to different soil texture, root distribution and irrigation management. The representative locations of each soil layer could be used to estimate the mean SWC well. The statistics of temporal stability of the SWC could be presented equally well with a low frequency of observation (30-day interval) as with a high frequency (5-day interval). Sampling frequency had little effect on the selection of the representative locations of the field mean SWC. This study provides useful information for designing the optimal strategy for sampling SWC at the oasis-desert ecotone in the arid inland river basin.

These projects represent important impacts on ecosystems, economies and local cultures as part of a trend in Latin America to the advancement of extractivist territorialities towards border areas which also means transgressing previous legal frameworks for the management of shared river basins. Given this context, strong resistance processes emerge from various narratives which together claim other territorialities in these river basins covering local and cross-border scales raising new debates and challenges to discuss eco-territorial conflicts in border areas.     Key words: extractivism, river basins, borders, territorialities, Patagonia.

  10. Emerging concepts for management of river ecosystems and challenges to applied integration of physical and biological sciences in the Pacific Northwest, USA

    Science.gov (United States)

    Rieman, Bruce; Dunham, Jason B.; Clayton, James

    2006-01-01

    Integration of biological and physical concepts is necessary to understand and conserve the ecological integrity of river systems. Past attempts at integration have often focused at relatively small scales and on mechanistic models that may not capture the complexity of natural systems leaving substantial uncertainty about ecological responses to management actions. Two solutions have been proposed to guide management in the face of that uncertainty: the use of “natural variability” in key environmental patterns, processes, or disturbance as a reference; and the retention of some areas as essentially unmanaged reserves to conserve and represent as much biological diversity as possible. Both concepts are scale dependent because dominant processes or patterns that might be referenced will change with scale. Context and linkages across scales may be as important in structuring biological systems as conditions within habitats used by individual organisms. Both ideas view the physical environment as a template for expression, maintenance, and evolution of ecological diversity. To conserve or restore a diverse physical template it will be important to recognize the ecologically important differences in physical characteristics and processes among streams or watersheds that we might attempt to mimic in management or represent in conservation or restoration reserves.

    2014-12-01

    As with many western US watersheds, the Nooksack River Basin faces strong pressures associated with climate variability and change, rapid population growth, and deep-rooted water law. This transboundary basin includes contributing areas in British Columbia, Canada, and has a long history of joint data collection, model development, and facilitated communication between governmental (federal, tribal, state, local), environmental, timber, agricultural, and recreational user groups. However, each entity in the watershed responds to unique data coordination, information sharing, and adaptive management regimes and thresholds, further increasing the complexity of watershed management. Over the past four years, participatory methods were used to compile and review scientific data and models, including fish habitat (endangered salmonid species), channel hydraulics, climate data, agricultural, municipal and industrial water use, and integrated watershed scale distributed hydrologic models from over 15 years of projects (from jointly funded to independent shared work by individual companies, agencies, and universities). A specific outcome of the work includes participatory design of a collective problem statement used for guidance on future investment of shared resources and development of a data-generation process where modeling results are communicated in a three-tiers for 1) public/decision-making, 2) technical, and 3) research audiences. We establish features for successful participation using tools that are iteratively developed, tested for usability through incremental knowledge building, and designed to provide rigor in modeling. A general outcome of the work is ongoing support by tribal, state, and local governments, as well as the agricultural community, to continue the generation of shared watershed data using models in a dynamic legal and regulatory setting, where two federally recognized tribes have requested federal court resolution of federal treaty rights

    On our river territories, the development of renewable energy and the restoration of the quality of the aquatic ecosystems both illustrate the need to reconcile the different usages of water resources while still guaranteeing proper functioning of the ecosystems. Hydroelectricity is the crux of the problem. Because of its mountainous hydrographic network and its favourable hydrology, the Adour-Garonne basin witnessed large-scale development of its hydroelectric potential throughout the 20. century. Approaching the question of hydroelectricity from the point of view of the river territories puts all the challenges facing them into their true perspective. Two distinct examples in the Adour-Garonne basin illustrate the partnership between the Water Agency and the local authorities in the Garonne and Dordogne basins: on the Garonne River, reconciling water usages with the maintenance of adequate water levels at times of drought; on the Dordogne River, reducing the impact of the hydro-peaking.

    Full Text Available Evaluation of fecundity is a key step to quantify the reproductive potential of individual fish and to understand the stock-recruitment relationship, increasing the knowledge of the state of a stock and improving the assessment of the spawning stock biomass. For the present work we investigated the fecundity and gonad development in anadromous female twaite shad, Alosa fallax (Lacépède, 1803, during the upstream spawning migration in the River Ulla. Thirty-four females were sampled with trammel nets between April and June 2011 in seating areas for this species, located at 24 km and 20 km from the Atlantic Ocean respectively. Fish were lengthed to the nearest millimetre, weighed to the nearest gram and aged by using scales. Factor condition (K was estimated as K= (TW/TL^3*100 where TW is fish total weight (g and TL is fish total length (cm. The ovaries from each female were removed and weighted to the nearest 0.01 gram. Approximately one gram samples were taken from the anterior, central and posterior regions of each ovary and preserved in 70 % ethanol. The number of eggs in each subsample was counted and the fecundity computed from the mean. Individual fecundity (F was computed and F was divided by the weight of the fish to estimate relative fecundity (FR. Also the gonadosomatic index (GSI was calculated to assess changes in fish maturity and spawning stage during the upstream migration. Female age ranged from 4 to 7 years and values of TL, TW, K and GSI were [mean ± SE (range]: 493 ± 7.3 mm (408-562 mm; 1,112 ± 53.7 g (592-1,626 g; 0.91 ± 0.02 (0.67-1.09 and 12.5 ± 0.47 (6.6-21.4 respectively. The value of fecundity (F was [mean ± SE (range]: 96,471 ± 6,493 oocytes (24,962 to 182,154 oocytes, while the relative fecundity (Fr was [mean ± SE (range]: 87,142 ± 3,592 oocytes (25,319 to 129,189 oocytes.

    Full Text Available Nation States have three defining characteristics: government of a territory, rapport with a group of people and ownership of a sovereign power. All three of these characteristics are undergoing changes. Several developments involve a redefinition of the “State” and produce numerous contradictions, which can only be solved if we consider the historicity of both the phenomenal essence and the conceptual essence of the State. We need to rethink and reconceptualise the State within the context of the new tendencies and transformations delineated by globalisation.

    Nuclear industry being composed of plants, laboratories, nuclear power stations, uranium mines, power lines and fluxes of materials from one facility to another is a strong shaper of the national territory. Contrary to other European countries, French nuclear industry is present all over the national territory. In 64 departments out of 101 there is at least one enterprise whose half of the revenues depends on nuclear activities. The advantage of such a geographical dispersion is when a nuclear activity is given up the social impact is less important: people tend to find a new job in the same region. French Nuclear power plants are generally set in remote places where population density is low and being the first employer by far of the area and being a major contributor to the city revenues, they are perceived as a key element the local population is proud of. In Germany, nuclear power plants are set inside dense industrial regions and appear as an industry just like any other.(A.C.)

    This report contains the results of a literature review on the carrying capacity of Pacific salmon in the Columbia River Basin. The objective of the review was to find the information gaps relative to the determinants of salmon carrying capacity in the Columbia River Basin. The review was one activity designed to answer questions asked in Measure 7.1A of the Councils Fish and Wildlife Program. Based, in part, on the information learned during the literature review and the other work accomplished during this study the Pacific Northwest National Laboratory (PNNL) state concluded that the approach inherent in 7.1A will not increase understanding of ecology, carrying capacity, or limiting factors that influence salmon under current conditions. To increase understanding of ecology, carring capacity, and limiting factors, it is necessary to deal with the complexity of the sustained performance of salmon in the Columbia River Basin. The PNNL team suggests that the regions evaluated carrying capacity from more than one view point. The PNNL team recommends that the region use the contextualistic view for evaluating capacity.

    Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

He also discusses whether territories then become dependent on nuclear activity, what happens when a nuclear plant stops, how the existence of a nuclear plant becomes an identity market for a territory, and how material flows also deal with geography. In the last part, the author notices that in Germany, nuclear industry is considered as an industry like any other one.

    Industrial ecology and sustainable development share the concept of territory. Two models of territorial development are proposed: Eco industrial Parks and Italian Districts. Both models use industrial-ecology concepts and strategies, but both are still far from incorporating sustainability.

    1998-01-01

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for inventory planning to determine BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The 1998 White Book is presented in two documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; and (2) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1997 Pacific Northwest Loads and Resources Study

First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for inventory planning to determine BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The 1998 White Book is presented in two documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; and (2) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1997 Pacific Northwest Loads and Resources Study.

  19. Propuesta de un Modelo de Inteligencia Territorial

    Directory of Open Access Journals (Sweden)

    2013-04-01

    Full Text Available A territory is built on the shared space and interaction between diverse public and private actors providing knowledge and resources that encourage development of the territory according to their own trajectories, visions and contexts. Territorial development depends on the competences and efforts of these actors to articulate territorial networks and to build knowledge assets around the territorial possibilities and potential, so they can act favorably in front of the changing environment, deploying both adaptive and predictive behavior. This paper proposes a conceptual model of territorial intelligence that includes the processes that allow territorial appropriation of knowledge as well as the development of a collective intelligence to promote the sustainable development of the territory.

    Full Text Available The article looks at the process of social and economic development in the Guayaquil river basin based on a model of agro exports commodity chains. The territory or region is analyzed by looking at social and economic dynamics as opposed to political administrative divisions, which covers a wider area that extends to the provinces of Los Ríos, Manabí and Santa Elena. This article is part of a more extensive research project on Guayaquil and the region, that looks at rural urban linkages and how the common feature of the regional economy is the dependence of the rural periphery on Guayaquil either for industrial or export processing. By focusing on the main agro-commodity chains that shape the territory, including coffee, cocoa and banana for export, as well as rice and corn for the internal market, one can see how regional development was built on the basis of the rural economy.

    A public power crisis in the Pacific Northwest arose over plans to build five nuclear power plants. This review traces the decisions made by the 23 members of the Washington Public Power Supply System (WPPSS), the Bonneville Power Administration, and 115 other utilities and industrial users, rural cooperatives, and investor-owned utilities during the planning and construction stages to the decision to terminate three plants. The effects of political action committees working for referenda to stop bond issues, suits by rate payers and cooperatives, and other financial problems led to the decision to mothball two units and halt construction of a third, which led to the loss of 6000 construction jobs. Work continues at one site at record levels. The region must submit a cost-effective conservation and renewable resource plan next year that will help to clarify the future of nuclear plants in the affected states

  9. Prey availability affects territory size, but not territorial display behavior, in green anole lizards

    2017-10-01

    The availability of food resources can affect the size and shape of territories, as well as the behaviors used to defend territories, in a variety of animal taxa. However, individuals within a population may respond differently to variation in food availability if the benefits of territoriality vary among those individuals. For example, benefits to territoriality may differ for animals of differing sizes, because larger individuals may require greater territory size to acquire required resources, or territorial behavior may differ between the sexes if males and females defend different resources in their territories. In this study, we tested whether arthropod abundance and biomass were associated with natural variation in territory size and defense in insectivorous green anole lizards, Anolis carolinensis. Our results showed that both male and female lizards had smaller territories in a habitat with greater prey biomass than lizards in habitats with less available prey, but the rates of aggressive behaviors used to defend territories did not differ among these habitats. Further, we did not find a relationship between body size and territory size, and the sexes did not differ in their relationships between food availability and territory size or behavioral defense. Together, these results suggest that differences in food availability influenced male and female territorial strategies similarly, and that territory size may be more strongly associated with variation in food resources than social display behavior. Thus, anole investment in the behavioral defense of a territory may not vary with territory quality.

    Full Text Available The article contains information on methods of geoecological zoning carried out based on the assessment of cartographic material using geoinformation technologies for the analysis of factographic cartographic material. The proposed methodology complements the existing methodological recommendations on geological and environmental research, developed by VSEGINGEO. The paper reflects the basic principles of obtaining the initial environmental information for creation of a map evaluation model of the Salekhard Area, and the rationale for selecting factors and numerical criteria for an integrated environmental assessment of the territory, taking into account the specifics of nature-technogenic conditions of the Severnoye Priobye region (West Siberia. The article briefly describes the main natural factors of the region of research, including landscape, geological, radiation, engineering-geological, geocryological, hydrogeological factors. Separate block describes the objects of technogenic load, including technogeneally-transformed landscapes in residential areas, corridors of transport communications, industrial and energy zones, and local ecologically significant objects. Ecological significance of natural and technogenic factors affected conducted ranking of their numerical parameters of the evaluation criteria. The article shows the application of a method of expert scoring for obtaining an integral assessment of the ecological state of the geological environment and creating a map of the regionalization of the Salekhard Area. Based on obtained cartographic model, a brief analysis of the existing ecological situation in the Salekhard Area shows the territories of favorable, satisfactory, tense, and crisis ecological states. The geoinformation-integrated model serves as the basis for determination of ecologically significant factors at the points of mapping the state of the geological environment, which allows for the further development of the

  15. New territory for NGL pipelines

    Turner, C.L.; Billings, F.E.

    1994-01-01

    Even though the NGL pipeline industry appears mature, new geographic territory exists for expansion of NGL pipelines. However, the most fertile territory that must be pursued is the collective opportunities to better link the existing NGL industry. Associations like the Gas Processors Association can not perform the role demanded by a need to share information between the links of the chain on a more real time basis. The Association can not substitute for picking up the phone or calling a meeting of industry participants to discuss proposed changes in policies and procedures. All stakeholders must participate in squeezing out the inefficiencies of the industry. Some expansion and extension of NGL pipelines will occur in the future without ownership participation or commitments from the supply and demand businesses. However, significant expansions linking new supply sources and demand markets will only be made as the supply and demand businesses share long-term strategies and help define the pipeline opportunity. The successful industries of the twenty-first century will not be dominated by a single profitable sector, but rather by those industries which foster cooperation as well as competition. A healthy NGL industry will be comprised of profitable supply businesses and profitable demand businesses, linked together by profitable pipeline businesses

  16. Plan4all – A European Approach to Spatial Data Used on Territorial Planning

    Directory of Open Access Journals (Sweden)

    GERGELY TÖRÖK

    2011-01-01

    Full Text Available In order to ensure the increased efficiency of European policies and the implementation of Structural Funds in a more balanced manner in the different territories of the country, a number of eight development regions have been established in Romania, corresponding to NUTS II level. In between these regions, as well as within each of them, a major concern is the diminution of economic and social disparities. Moreover, these disparities can manifest themselves in a cross-border context, jumping the administrative boundaries of regions and even neighbouring countries. In this sense, development plans provide certain measures in order to stimulate a more balanced development of the territories, using spatial planning as the actual support in identifying factors that lead to the emergence and intensifying of regional disparities. The present paper focuses on these aspects related to spatial planning data in the context of the recent European initiatives, through the activities of the Plan4all project that is being implemented by a European consortium. Romania is partner in this project and is represented by the North-West Regional Development Agency (North-West RDA. The paper presents the achievements of the running Plan4all project until the present day, as well as the involvement and the contributions of the North-West RDA so far.

    D. maculates is a kind of specialized Schizothoracinae fish has been locally listed as a protected animal in Xinjiang Province, China. Ili River located in north of Tianshan Mountain and Tarim River located in north of Qinghai-Tibetan Plateau were two main distribution areas of this fish. To investigate the genetic diversity and genetic structure of D. maculates, four populations from Tarim River system and two populations from Ili River system were collected in this study. A 570-bp sequence of the control region was obtained for 105 specimens. Twenty-four haplotypes were detected from six populations, only Kunes River population and Kashi River population shared haplotypes with each other. For all the populations examined, the haplotype diversity ( h) was 0.904 8±0.012 6, nucleotide diversity (π) was 0.027 9±0.013 9, and the average number of pairwise nucleotide differences ( k) was 15.878 3±7.139 1. The analysis of molecular variance (AMOVA) showed that 86.31% of the total genetic variation was apportioned among populations, and the variation within sampled populations was 13.69%. Genetic differences among sampled populations were highly significant. F st statistical test indicated that all populations were significantly divergent from each other ( P<0.01). The largest F st value was between Yurungkash River population and Muzat River population, while the smallest F st value was between Kunes River population and Kashi River population. NJ phylogenetic tree of D-loop haplotypes revealed two main clades. The neutrality test and mismatch distribution analysis suggested that the fish had went through a recent population expansion. The uplift of Tianshan Mountain and movement of Qinghai-Tibetan Plateau might contribute to the wide genetic divergence of D. maculates in northwest China.

    Full Text Available The aim of this research is to analyze territorial capital as a new paradigm to make best use of endogenous assets. The study is dealing with the preconditions, meaning and possible theoretical taxonomies of territorial capital. In this study I emphasize that the cumulative effects of regional potentials are more important than economies of scale and location factors. I present different approaches and interpretations of territorial capital, then make an attempt to create an own model. I try to find answers for questions, such as why territorial capital shows a new perspective of urban and regional development; how cognitive elements of territorial capital provide increasing return; how territorial capital influences competitiveness and what kind of relation it has with cohesion.

Such aconstruct is vital for territorial sustainable development and supposes thecreation of a specific body of knowledge from distinctive local resourceexploitation and unique value creation and allocation. Territorial mechanismdesign is a typical management decision about identification, ownership andcontrol of specific strategic capabilities and their combination in a distinctiveterritorial portfolio. The most difficult responsibility is to allocate the territorialvalue added which is a source of conflict among territorial components. Ourcurrent paper research covers the basics of two complementary territorialpillars-rural and tourism potential and proves the lack of specific designmechanisms which explain the current diminishing value of Galati Brailaregion.

    Full Text Available The territory is understood as an appropriate space, delimitated by power relations, and constituted by material and symbolic relations which provide elements to the territorialities development and for forming men and women identities. In the territory of familiar production, the sexual division of labor and of spaces causes the 'invisibility' of women's work in the productive sphere, fact that influences on the construction of the rural women’s identity. However, women exercise their territorialities in both spaces and their productive and reproductive activities are fundamental to the family's livingness and permanence in the countryside. In this sense, it proposes to analyze the territorialities and the territorial identity of the subjects of the countryside and ascertain how this discussion contributes to the recognition of rural woman's identity. To the development of this research, have been taken theoretical research about: territory, territoriality, identity, gender and domestic space.

    Johnson, Gary E.; Neitzel, D.A.; Mavros, William V.

    1996-05-01

    This report contains the proceedings of a workshop held during 1995 in Portland, Oregon. The objective of the workshop was to assemble a group of experts that could help us define carrying capacity for Columbia River Basin salmonids. The workshop was one activity designed to answer the questions asked in Measure 7.1A of the Council`s Fish and Wildlife Program. Based, in part, on the information we learned during the workshop we concluded that the approach inherent in 7.1A will not increase understanding of ecology, carrying capacity, or limiting factors that influence salmon under current conditions. Measure 7.1A requires a definition of carrying capacity and a list of determinants (limiting factors) of capacity. The implication or inference then follows that by asking what we know and do not know about the determinants will lead to research that increases our understanding of what is limiting salmon survival. It is then assumed that research results will point to management actions that can remove or repair the limiting factors. Most ecologists and fisheries scientists that have studied carrying capacity clearly conclude that this approach is an oversimplification of complex ecological processes. To pursue the capacity parameter, that is, a single number or set of numbers that quantify how many salmon the basin or any part of the basin can support, is meaningless by itself and will not provide useful information.

    Full Text Available Whereas in Romania there are 19 national minorities officially acknowledged by Romanian state, up to present, one did not manage to adopt a special law of national minorities. We identify special disposals related to national minorities in Romanian Constitution, in the law of local public administration, the law of education, the law concerning the election of the Chamber of Deputies and Senate, the law related to political parties, the law for the election of the authorities of local public administration, the law concerning the combating of all forms of discrimination. In the last project of the Law concerning the statute of national minorities in Romania, a new concept is introduced: cultural autonomy of minorities. The cultural autonomy is a form of non-territorial autonomy. Nevertheless, Romania is criticised by some international organisations for the fact that the organisations of national minorities represented in the Parliament of Romania have instituted a monopole, therefore no other organisation of any minority is allowed to participate to the elections.

    Full Text Available The different contemporary approaches that touches the development focus from the territorial perspective can be classified into two big surveys of the so called new regionalism: the globalist survey and the regionalist survey. Some authors have preferred to focus on the regionalist studies in an excessively optimistic way, this way deserving being critically analysed. In spite of all that, it is possible to visualize a scenery of breathing answers to the challenges of the development territorialization in a way that the different forms of social territorial organization, the territorial collective innovation and the necessary reconsideration of the State´s role deserve destak. This way, it is opened the possibility that the progressive trajectory of territorial development can be managed and administrated from the articulated action of public and private actors.

    2005-01-01

    This paper discusses the application of a bioventing system used to treat soil and groundwater contaminated with diesel at a commercial property in Yellowknife. Contamination was caused by a broken pipe connected to an underground storage tank. A bioventing trial was proposed as the most economical method of remediating residual contamination following several years of product recovery. A background of earlier phased product recovery methods was provided. Sufficient heliotrophic bacteria was present in the groundwater for aerobic bioremediation of the petroleum hydrocarbon impacted soil and groundwater. Details of monitoring wells and recovery rates were presented, as well as installation procedures for the bioventing system, which included 3 air injection wells, 6 vadose zone observation wells and a blower fan with associated piping to blow air into the subsurface. The system operated for 12 days to establish subsurface conditions and evaluate effectiveness, and was subsequently used for various periods of duration from 2002 to 2004. Results for all periods of operation were provided. It was concluded that the system was effective in increasing subsurface oxygen concentrations to stimulate microbial bioremediation in the vadose zone soil. Estimated remediation time ranged from 3 to 5 years. The radius of influence of the system was in excess of 29 m. Changes in the water table meant that wells initially thought to be free of hydrocarbons became recontaminated. Further operations and monitoring of the bioventing system were recommended, including soil sampling to determine concentrations of hydrocarbons remaining at the site in comparison to other soil criteria. Monitoring costs were estimated at $10,000 per year. It was suggested that there was a potential for the application of this system in other northern contaminated areas. 3 figs

  7. Temporal, geomagnetic and related attributes of kimberlite magmatism at Ekati, Northwest Territories, Canada

    Lockhart, Grant; Grütter, Herman; Carlson, Jon

    2004-09-01

    This paper outlines the development of a multi-disciplinary strategy to focus exploration for economic kimberlites on the Ekati property. High-resolution aeromagnetic data provide an over-arching spatial and magnetostratigraphic framework for exploration and kimberlite discovery at Ekati, and hence also for this investigation. The temporal, geomagnetic, spatial and related attributes of kimberlites with variable diamond content have been constrained by judiciously augmenting the information gathered during routine exploration with detailed, laboratory-based or field-based investigations. The natural remanent magnetisation of 36 Ekati kimberlites has been correlated with their age as determined by isotopic dating techniques, and placed in the context of a well-constrained geomagnetic polarity timescale. Kimberlite magmatism occurred over the period 75 to 45 Ma, in at least five temporally discrete intrusive episodes. Based on current evidence, the older kimberlites (75 to 59 Ma) have low diamond contents and are distributed throughout the property. Younger kimberlites (56 to 45 Ma) have moderate to high diamond contents and occur in three distinct intrusive corridors with NNE to NE orientations. Economic kimberlite pipes erupted at 55.4±0.4 Ma along the A154-Lynx intrusive corridor, which is 7 km wide and oriented at 015°, and at 53.2±0.3 Ma along the Panda intrusive corridor, which is 1 km wide and oriented at 038°. The intrusion ages straddle a paleopole reversal at Chron C24n, consistent with the observation that the older economic kimberlites present as aeromagnetic "low" anomalies while the younger economic pipes are characterised as aeromagnetic "highs". The aeromagnetic responses for these kimberlites are generally muted because they contain volcaniclastic rock types with low magnetic susceptibility. Kimberlites throughout the Ekati property carry a primary natural magnetic remanence (NRM) vector in Ti-bearing groundmass magnetite, and it dominates over vectors related to induced magnetisation. Magnetostratigraphic correlation of Ekati kimberlites may therefore present a powerful adjunct to existing exploration techniques, mainly because the diamond content of Ekati kimberlites apparently is related more to the age of eruption than to any other parameter investigated in this work.

    2005-01-01

    This paper outlines major stages of an ongoing remediation project caused by a power generating plant in the Dene Hamlet of Tulita. High levels of soil contamination were caused by the plant's operations as well as accidental petroleum hydrocarbon (PHC) spills. The decommissioning of the plant required that the site be remediated. Challenges faced by the remediators included the high level of contamination, the remote location of the community, as well as the fact that the site was located in the centre of the community. In addition, the soil in the impacted site was fine, and a 20 cm thick layer of peat acted as sponge, absorbing and trapping hydrocarbons. Remedial criteria was outlined according to Canada-Wide Standards for fine-grained soil in an industrial setting. The technology used for the project was Biopile, a process consisting of installing wells in the contaminated zone in order to provide the aeration required for PHC biodegradation and to condition the soil on a regular basis in order to promote optimal treatment conditions throughout the impacted material. Results indicated that the first 2 months were successful in reducing initial PHC levels. However, the following treatment season did not show as much degradation. An investigation revealed that nitrogen and phosphorus levels were insufficient to sustain microbial activity, as a result of lower than normal temperatures in the area for that season. Nutrients were added to the soil to re-establish the appropriate treatment conditions. It was concluded that the technology used presented numerous advantages. Overall disturbance of the area was reduced, and allowed other measures to be implemented, including segregation of the highly impacted peat layer. It was expected that remediation objectives for the entire site will be met by July 2005. 3 refs., 3 tabs

    Injury is the leading cause of death for young people in Canada. For those living in the northern territories (Yukon, Nunavut, and the Northwest Territories), injury represents an even greater problem, with higher rates of injury for people of all ages in northern areas compared with the rest of Canada; however, no such comparative studies have focussed specifically on non-fatal injury in youth. To profile and examine injuries and their potential causes among youth in the northern territories as compared with other parts of Canada. Cross-sectional data from the 2009/2010 Health Behaviour in School-aged Children survey (youth aged 11-15 years) were examined for the Canadian northern territories and the provinces (n=26,078). Individual survey records were linked to community-level data to profile injuries and then study possible determinants via multilevel regression modelling. The prevalence of injury reported by youth was similar in northern populations and other parts of Canada. There were some minimal differences by injury type: northern youth experienced a greater percentage of neighbourhood (pCanada. Given previous research, this was unexpected. When implementing injury prevention initiatives, individual and community-level risk factors are essential to understand; however, specific positive safety assets that might exist in different community contexts must also be considered.

    The Pacific Northwest (comprised of the states of Alaska, Idaho, Montana, Oregon, Washington and Wyoming) can by several measures be regarded as a national warehouse of fossil energy resources. This condition coupled with an evolving national policy stressing utilization of fossil fuels in the near term prior to development of more advanced technologies for energy supply, could result in the imposition of major changes in the region's environmental, socioeconomic and possibly health status. The objective of the Pacific Northwest Regional Assessment Program is to establish and exercise an integrated analytical assessment program for evaluation of these potential changes that may result from various energy development or conservation scenarios. After consideration of a variety of approaches to integrated assessment at a regional level, Pacific Northwest Laboratories (PNL) has concluded that dynamic simulation techniques provide the best available approach to evaluating the issues pertinent to the Northwest. As a result, the PNW Regional Assessment Program has been structured in a framework involving ten sectors. Each of these sectors involve their own submodels that receive information either from outside the model as exogenous inputs or from other sector submodels

    Hydro regulation models provide extensive support for analyzing the efficacy of salmon recovery plans in the Northwest. Power planners developed these computer programs to help plan and efficiently operate a large multiple use river system. The models represent physical relationships and operational requirements on the system. They also simulate coordinated system operations for efficient power generation. These models are being pressed into service to provide data for fish recovery plans. They provide important information about hydro system capabilities and responses to recovery programs. However, the models cannot meet all of the analytical needs of fish biologists working toward salmon recovery

    An integrated place-based approach for the improvement of territorial and social cohesion is the new instance for planning disciplines, coming from EU New Cohesion Policies. This paper considers the territorial impact assessment of regional development policies as a precondition in order to develop balanced and effective operative programs at national and regional levels. The contribution of `open data' appears to be mature in order to support this application and in this paper we present a spatial analysis technique for the evaluation of EU funds effects at territorial level, starting from open data by Open Cohesion. The application is focused on internal areas of Basilicata Region: Agri river Valley. A complex contest, where environmental and agricultural traditional vocations conflict with a recent development of oil extraction industries. Conclusions concern further applications and perspectives to improve and support regional development planning considering the exploitation of open data sources and spatial analysis.

    Full Text Available Purpose and Originality: The article is overview of Balkan changing wars. Balkan is historical area of conflict, however there are wars, which should be singled out due to their influence on the territory as well as on the population and political situation in the region. Method: In the article historical descriptive method is used. We were trying to describe pretexts, causes, courses, endings and consequences of the largest armed conflicts. Result: We can say that main historical wars in Balkans were Battle of Frigidus River, Battle of Kosovo, First and Second Balkan war, Civil war in Yugoslavia and Kosovo war. Society: The results should raise the awareness of the nature of the territory as well as increase the understanding of the mixing different influences in the territory of Balkans. Limitation: Article is leaving out two world wars, due to their different scale and impact on the history, which goes beyond the borders of Balkan.

  16. Animal interactions and the emergence of territoriality.

    Directory of Open Access Journals (Sweden)

    Luca Giuggioli

    2011-03-01

    Full Text Available Inferring the role of interactions in territorial animals relies upon accurate recordings of the behaviour of neighbouring individuals. Such accurate recordings are rarely available from field studies. As a result, quantification of the interaction mechanisms has often relied upon theoretical approaches, which hitherto have been limited to comparisons of macroscopic population-level predictions from un-tested interaction models. Here we present a quantitative framework that possesses a microscopic testable hypothesis on the mechanism of conspecific avoidance mediated by olfactory signals in the form of scent marks. We find that the key parameters controlling territoriality are two: the average territory size, i.e. the inverse of the population density, and the time span during which animal scent marks remain active. Since permanent monitoring of a territorial border is not possible, scent marks need to function in the temporary absence of the resident. As chemical signals carried by the scent only last a finite amount of time, each animal needs to revisit territorial boundaries frequently and refresh its own scent marks in order to deter possible intruders. The size of the territory an animal can maintain is thus proportional to the time necessary for an animal to move between its own territorial boundaries. By using an agent-based model to take into account the possible spatio-temporal movement trajectories of individual animals, we show that the emerging territories are the result of a form of collective animal movement where, different to shoaling, flocking or herding, interactions are highly heterogeneous in space and time. The applicability of our hypothesis has been tested with a prototypical territorial animal, the red fox (Vulpes vulpes.

It is necessary to overcome the dichotomy space without time and time without space and to un think the world of the social, leaving out the analysis of problems that overcome the fields of the disciplines. The most appropriate approach would be to recognize the existence of a spacetime dimension, or if one wants, time space and to define the geography as a social science that considers the territory like a social construction through the spacetime

    2007-01-01

    The impact of global warming on permafrost terrain was discussed with particular reference to the structural stability and performance reliability of the proposed pipelines and roads in the Mackenzie River Valley in the Northwest Territories. Engineers, regulators and decision makers responsible for the development of these networks must have access to information about current and future terrain conditions, both local and regional. The Geological Survey of Canada is developing an ArcGIS resident, multi-component terrain analysis methodology for evaluating permafrost terrain in terms of the probable geothermal and geomorphological responses to climate warming. A GIS-integrated finite-element transient ground thermal model (T-ONE) can predict local-regional permafrost conditions and future responses of permafrost to climate warming. The influences of surface and channel hydrology on local erosion potentials can be determined by analyzing the topographic and topologic characteristics of the terrain. A weights of evidence-based landscape-process model, currently under development, will consider multiple terrain factors for mapping terrain that is susceptible to slope failure, subsidence or erosion. This terrain analysis methodology is currently being applied to a 2 km buffer spanning the proposed Mackenzie Gas Pipeline right-of-way, and along winter and all-weather road networks in the Mackenzie River Valley. Initial ground thermal modeling has identified thermally sensitive terrain for which permafrost will either completely disappear or warm significantly to near isothermal conditions within the next 25 to 55 years

    The arid region of Northwest China, located in the central Asia, responds sensitively to global climate change. Based on the newest research results, this paper analyzes the impacts of climate change on hydrology and the water cycle in the arid region of Northwest China. The analysis results show that: (1) In the northwest arid region, temperature and precipitation experienced "sharply" increasing in the past 50 years. The precipitation trend changed in 1987, and since then has been in a state of high volatility, during the 21st century, the increasing rate of precipitation was diminished. Temperature experienced a "sharply" increase in 1997; however, this sharp increasing trend has turned to an apparent hiatus since the 21st century. The dramatic rise in winter temperatures in the northwest arid region is an important reason for the rise in the average annual temperature, and substantial increases in extreme winter minimum temperature play an important role in the rising average winter temperature; (2) There was a significant turning point in the change of pan evaporation in the northwest arid area in 1993, i.e., in which a significant decline reversed to a significant upward trend. In the 21st century, the negative effects of global warming and increasing levels of evaporation on the ecology of the northwest arid region have been highlighted; (3) Glacier change has a significant impact on hydrology in the northwest arid area, and glacier inflection points have appeared in some rivers. The melting water supply of the Tarim River Basin possesses a large portion of water supplies (about 50%). In the future, the amount of surface water will probably remain at a high state of fluctuation. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Aim. Analysis of the population dynamics and changes in the share of arable land in the structure of land use separate territory for several historical periods, and to determine the causes of these changes. Methods. Studies have used forwarding, statistical methods, and the method of cartographic modeling and retrospective analysis. Results. Analysis of the results of the population census allows speaking about the general negative dynamics in the rural population of the Volgograd region in general and river basin Bolshaya Golubaya in particular. Historical and cartographic analysis has shown the dependence of the arable lands of the number of residents on the territory residents. In addition, the population of the territory is significantly affected by soil fertility. Main conclusions. The population of the river basin Bolshaya Golubaya over the past hundred years have steadily decreased, as due to various socio-economic reasons, such as consolidation of rural settlements, the planned destruction of farm system, moving people into the city, and due to the difficult climatic conditions for farming: poor soil fertility, high degree of erosion areas, poor soil conditions of the territory.

  5. Enchained territories, migratory displacements and adaptive ruralities

    Directory of Open Access Journals (Sweden)

    Luis Camarero

    2017-05-01

    Full Text Available The text is concerned with the ways in which the territories, in this case the different rural areas and localities, are integrated, linked or dissociated into processes and chains of production and economic of a global order. The connection between territories and economic chains occurs through flows of goods, inputs and capital, but also through migratory movements and diverse mobility practices. The process of social division of labor generates new logics of integration / disintegration of the regions in the socioeconomic process, and different mobility demands associated with these changes. The hypothesis that encloses this text is that places and territories will reach to insert in global chains if they develop capacities of adaptability to the productive conditions and especially they manage to reduce the territorial friction guaranteeing the migratory management and mobility of the labor force. With this point of view the socio-agricultural evolution of the rural areas in Spain is contemplated from the end of century XIX

    Markon, Carl; Schroff, Eric

    2016-01-01

    The Northwest Boreal Landscape Conservation Cooperative (NWB LCC) is a voluntary, diverse, self-directed management-science partnership, informing and promoting integrated science, sustainable natural and cultural resource management, and conservation to address impacts of climate change and other stressors within and across ecosystems. The NWB LCC area includes parts of Alaska, Yukon, Northwest Territories, and British Columbia. Our partnership reflects both the broad geographic scope and an extensive array of active and engaged participants including resource management organizations, government representatives, policy makers, Tribes and First Nations, industry leaders, researchers, non-governmental organizations, and research/education institutions. Bringing together diverse partners will help assure the northwest boreal is a functioning, sustainable landscape. We live in an era of profound conservation challenges, including the loss and fragmentation of habitats, genetic isolation, invasive species, and unnatural wildfire. The effects of rapidly changing climate are already evident on the landscape. In these circumstances, it is imperative that natural resource management agencies, science providers, Tribes, First Nations, conservation organizations, and other stakeholders work together to understand the drivers and impacts of landscape change and to determine how best to address those challenges. Further, it is essential that the public and communities receive clear communication about the vision and activities of the NWB LCC. Open public access to NWB LCC activities and products will promote acceptance and support of the science that guides potential changes in management action and conservation strategy. This strategic plan provides a great opportunity for the NWB LCC to share our approach and intentions to the LCC members, collaborators, communities, and the public at large.

    Full Text Available El proceso jurídico-administrativo abierto en 1993 ante los poderes del Estado Paraguayo para la reivindicación de una parte del territorio de los Totobiegosode, grupo local del pueblo Ayoreo, es experiencia singular en el país. En el proceso, los instrumentos jurídicos que garantizan derechos de los pueblos indígenas están sometidos a prueba no sólo en lo relativo a la coherencia de sus postulados, disposiciones y procedimientos, sino también en función a las constricciones del contexto socio-político. El trabajo expone el abordaje interdisciplinario de la gestión conjunta entre los Ayoreo Totobiegosode y profesionales no indígenas, como las distintas dimensiones administradas en la reivindicación territorial: étnica, ambiental, patrimonial cultural y de derechos humanos. La existencia de sub-grupos Totobiegosode sin contacto con la sociedad envolvente, y la transformación acelerada de la región del Chaco Paraguayo, son condiciones particulares de los trámites aún en curso.The legal-administrative process started in 1993 before the Paraguayan governmental powers to claim part of the land of the Totobiegosode, an indigenous local group of the Ayoreo people, is a unique experience in the country. In the process, the legal instruments that guarantee the rights of the indigenous people are not only tested with regards to the coherence of its principles, regulations and procedures, but also with regards to the constraints of the socio-political context. This paper explains the interdisciplinary approach of joint management between the Ayoreo Totobiegosode and non-indigenous team of professionals, such as the different aspects managed during the land claims: ethnic, environmental, cultural heritage and human rights. The existence of sub-groups of Totobiegosode without contact with the surrounding society, currently called "in isolation", and the accelerated transformation of the Paraguayan Chaco region, are particular conditions of

EU 2020 Strategy and other EU documents create a favorable frame in order to achieve the priorities set by reconsidering the territorial pact concept. Recent documents define the partnership agreement concept, which seems to be more rigid and less flexible than the territorial pact. Having as a starter point Romania’s specifics, there are individualized 10 thematic territorial pacts and 8 global pacts. They must generate territorial synergies capable of ensuring the coherence between regions, states and the European Union as a whole.

    2016-11-01

    Full Text Available The aim of this paper is to ascertain the territorial dimension of the fishing economy in Guaymas, Mexico. The geographical studies addressing this economic activity in Mexico and published in the last decades are scarce. For this reason, this research work is particularly important, as it outlines the fishery activities in one of the most active sea-ports of northwest Mexico, from a territorial perspective. The first part of this article explains why and how Economic Geography addresses fishery activities and which methodology we pursued to carry out this investigation, based on studies carried out by geographers, particularly in France and Argentina. Then the paper describes the natural conditions prevailing in the Gulf of California (also known as Sea of Cortez, a large inlet of the eastern Pacific Ocean that is rich in marine resources and where most of the main national fisheries are located. Guaymas is one of the most important sea ports located along the Gulf of California for its long fishing history and the variety of fishing species captured. This port, located in the southern coast of the state of Sonora, is a mediumsized city with a little over 100 thousand inhabitants; a considerable proportion of the local labor force works in the fishery sector and associated industries. Today, the fishery sector in Guaymas is characterized by a large number of artisan fishermen, a prominent fleet preciand the regular practise of illegal catching. This port is the seat of large enterprises, such as Ocean Garden, involved in the industrialization of catches (basically fish oil and fish meal and their further commercialization within and outside Mexico. Two commercially important species have played a key role in the evolution and outline of the current territorial structure of fisheries in Guaymas. One is shrimp, with a fishery that recorded a boom during 1970-1990, bringing along a number of benefits for local fishermen in Sonora. This fishery

    Full Text Available This study describes the diversity and the subsistence fishing territoriality of traditional populations of a village Ashaninka and two Kaxinawá living at the margins of Breu River (Brasil/Peru. In general, samplings in the dwellings were carried out late in the afternoon, as the fishermen arrived in the village. The data were analysed in an exploratory way through the index of pondered dominance (ID%, by analysis of variance and by a correspondence analysis in order to determine the associations of the fish species and the fishing spots between the villages of the Indigenous Reserve. The results of the analysis of variance demonstrated that differences exist between the fish diversities of the catches. However, post-hoc tests only detected differences in diversities between the hand fishhook and the other fishing gears (bow and arrow, castnets and rotenone tingui. Although the use of bow and arrow resulted in a low capture (Kg, this fishing strategy is associated with a high fishing diversity, in terms of number of species. These results demonstrate that there is no overlap in the frequency of the visits to the fishing spots between the Ashaninka and Kaxinawá populations. This pattern is the same found for the correspondence analysis for the fish species, which describes the relationship between the deep pools environments exploited by the fishermen Ashaninka and Kaxinawá of Mourão. These ethnic populations still continue to maintain a strong cultural and cosmological tradition, with their territories defined in an informal way of the upper Juruá area.Este estudo tem o objetivo de descrever a diversidade e a territorialidade pesqueira de subsistência das populações tradicionais de uma aldeia Ashaninka e duas Kaxinawá vivendo à beira do rio Breu.

    2015-10-01

    Full Text Available The winter regime of river-ice covers in high northern latitude regions is often a determining factor in the management of water resources, conservation of aquatic ecosystems and preservation of traditional and cultural lifestyles of local peoples. As ground-based monitoring of river-ice regimes in high northern latitudes is expensive and restricted to a few locations due to limited accessibility to most places along rivers from shorelines, remote sensing techniques are a suitable approach for monitoring. This study developed a RADARSAT-2 based method to monitor the spatio-temporal variation of ice covers, as well as ice types during the freeze-up period, along the main channel of the Slave River Delta in the Northwest Territories of Canada. The spatio-temporal variation of ice covers along the river was analyzed using the backscatter-based coefficient of variation (CV in the 2013–2014 and 2014–2015 winters. As a consequence of weather and flow conditions, the ice cover in the 2013–2014 winter had the higher variation than the 2014–2015 winter, particularly in the potential areas of flooded/cracked ice covers. The river sections near active channels (e.g., Middle Channel and Nagle Channel, Big Eddy, and Great Slave Lake also yielded higher intra-annual variation of ice cover characteristics during the winters. With the inclusion of backscatter and texture analysis from RADARSAT-2 data, four water and ice cover classes consisting of open water, thermal ice, juxtaposed ice, and consolidated ice, were discriminated in the images acquired between November and March in both the studied winters. In addition to river geomorphology and climatic conditions such as river width, sinuosity or air temperature, the fluctuation of water flows during the winter has a significant impact on the variation of ice cover as well as the formation of different ice types in the Slave River. The RADARSAT-2 based monitoring algorithm can also be applied to other

    Major flooding occurred August 24–25, 2016, in the Upper Iowa River Basin and Turkey River Basin in northeastern Iowa following severe thunderstorm activity over the region. About 8 inches of rain were recorded for the 24-hour period ending at 4 p.m., August 24, at Decorah, Iowa, and about 6 inches of rain were recorded for the 24-hour period ending at 7 a.m., August 24, at Cresco, Iowa, about 14 miles northwest of Spillville, Iowa. A maximum peak-of-record discharge of 38,000 cubic feet per second in the Upper Iowa River at streamgage 05388250 Upper Iowa River near Dorchester, Iowa, occurred on August 24, 2016, with an annual exceedance-probability range of 0.2–1 percent. High-water marks were measured at six locations along the Upper Iowa River between State Highway 26 near the mouth at the Mississippi River and State Highway 76 about 3.5 miles south of Dorchester, Iowa, a distance of 15 river miles. Along the profiled reach of the Turkey River, a maximum peak-of-record discharge of 15,300 cubic feet per second at streamgage 05411600 Turkey River at Spillville, Iowa, occurred on August 24, 2016, with an annual exceedance-probability range of 1–2 percent. A maximum peak discharge of 35,700 cubic feet per second occurred on August 25, 2016, along the profiled reach of the Turkey River at streamgage 05411850 Turkey River near Eldorado, Iowa, with an annual exceedance-probability range of 0.2–1 percent. High-water marks were measured at 11 locations along the Turkey River between County Road B64 in Elgin and 220th Street, located about 4.5 miles northwest of Spillville, Iowa, a distance of 58 river miles. The high-water marks were used to develop flood profiles for the Upper Iowa River and Turkey River.

    As the recent law on energy transition defined a legal framework which allowed the action of local authorities in the field of energy, and resulted in the creation of local or territorial energy utilities by these authorities or other actors, this report proposes a presentation of examples of territorial energy utilities or operators. These examples are chosen in different French towns, district or regions (Vienne, Montpellier, Lannion, Pays de Vilaine, Lot, Ile-de-France, Rhone-Alpes) but also in Germany and Austria. Before presenting these experiments, the authors describe and discuss the French legal framework of territorial energy transition.

    Full Text Available This article draws from the preliminary findings of an ongoing appliedresearch program on rural territorial dynamics carried out by the Latin American Center for Rural Development (RIMISP. The article provides some initial findings on 4 territories, of the 11 territories that are part of the overall study. The case studies include the island of Chiloé in southern Chile, the province of Tungurahua in Ecuador, a dairy farm region of Santo Tomás Nicaragua and Cuatro Lagunas near Cuzco Perú. Rural areas in Latin America are characterized by their dual nature with agro-exporting enclaves linked to global value chains alongside impoverished peasant economies, leading to differentiated policy recommendations. The research attempts to find relationships between reduced poverty and inequality in winning regions, measured by three variables, with issues of access to resources, human capital, political empowerment, markets and institutions, with particular attention to innovative social coalitions.

    Full Text Available This article discusses how territory and linking notions articulate with the health field in Brazil, in view of the relations that are established between health staff and certain social groups who see in the movement a logic of life, survival and resistance: the nomads. The concept of territory is an important organizer of Brazilian’s public policies, and is closely related to inclusion. The data were collected through participant observation of the daily work of two teams of Family Health Strategy, in a medium-sized city located in the state of Rio Grande do Sul. For these services, nomadism is seen as a nuisance. On the other hand, include not only acquires a sense of attachment and population control, but the demarcation of belonging territories, from the investment of the relation of users with health services.

    2012-07-01

    Full Text Available The aim of this paper is to reveal the nuclei, flows and surfaces generated by tourism in Guatemala that, nowadays, constitute the basis for the promotion of the country in the international market. Following the trend in Central America, and after a long civil war, Guatemala is encouraging the growth of its tourism economy. The starting point of this research is rooted in the fact that there are only a handful of places, distributed over the Guatemalan territory, that articulate the tourist flows (constituted mainly by international visitors and onto which tourism surfaces are being constructed. We assume that this territorial structure is still weak, does not include all areas of the country and it is mostly dependant on regional emitting markets. The context of the territorial structure of tourism in Guatemala suggests that all countries in the region are competing to get access to the international tourism market and that this competition will be decided in favour of those nations that mastermind the administration of their natural and cultural resources. At the end of the text, we comment on the basics of the territorial structure found by our study.

    Seleznev, V. S.; Soloviev, V. M.; Emanov, A. F.

    The outcomes of modern geophysical researches of the Geophysical Survey SB RAS, directed on study of geodynamic situation in large industrial and civil centers on the territory of Siberia with the purpose of an evaluation of seismic risk of territories and prediction of origin of extreme situations of natural and man-caused character, are pre- sented in the paper. First of all it concerns the testing and updating of a geoinformation system developed by Russian Emergency Ministry designed for calculations regarding the seismic hazard and response to distructive earthquakes. The GIS database contains the catalogues of earthquakes and faults, seismic zonation maps, vectorized city maps, information on industrial and housing fund, data on character of building and popula- tion in inhabited places etc. The geoinformation system allows to solve on a basis of probabilistic approaches the following problems: - estimating the earthquake impact, required forces, facilities and supplies for life-support of injured population; - deter- mining the consequences of failures on chemical and explosion-dangerous objects; - optimization problems on assurance technology of conduct of salvage operations. Using this computer program, the maps of earthquake risk have been constructed for several seismically dangerous regions of Siberia. These maps display the data on the probable amount of injured people and relative economic damage from an earthquake, which can occur in various sites of the territory according to the map of seismic zona- tion. The obtained maps have allowed determining places where the detailed seismo- logical observations should be arranged. Along with it on the territory of Siberia the wide-ranging investigations with use of new methods of evaluation of physical state of industrial and civil establishments (buildings and structures, hydroelectric power stations, bridges, dams, etc.), high-performance detailed electromagnetic researches of ground conditions of city

  6. De-Territorialization and Re-Territorialization of “the social”. A debate

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available Deterritorialization has been used as an anthropological concept to designate the weakened ties between culture and place: Certain cultural/social processes and relations seem to increasingly transcend their previously given territorial boundaries in flexible capitalist societies. At the same time, policy studies, especially Studies on Governmentality, have emphasized the re-territorialization of the social, in which the former national welfare arrangements (welfare and nation state as the scale of bio-political integration patterns are more and more substituted by small scaled inclusion areas (e.g. neighbourhoods, districts and communities. Drawing on Deleuze and Guattari, de-territorialization processes have therefore always to be understood as combined with processes of a re-territorialization, producing new spatial formations. In this view, spatial arrangements and connections are not given and static structures, but controversial and unstable – nevertheless they are influential.

    2011-02-16

    The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL Site comply with applicable laws, policies, and DOE orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL Site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental setting of the PNNL Site is described in Larson and Downs (2009). There are currently two facilities on the PNNL Site: the William R. Wiley Environmental Molecular Sciences Laboratory (EMSL), and the recently completed Physical Sciences Facility (PSF). This report describes the results of the annual survey of the biological resources found on the undeveloped portions of the PNNL Site in 2010. A brief description of the methods PNNL ecologists used to conduct the surveys and the results of the surveys are presented. Actions taken to fully delineate noxious weed populations discovered in 2009 and efforts in 2010 to control those weeds also are described. Appendix A provides a list of plant and

    Family violence is a complex, multidimensional and pervasive presence in many Aboriginal communities. Although practitioners acknowledge that intimate partner violence (IPV) is a grave concern in the North, as in other jurisdictions in Canada, there is a paucity of literature about IPV and the local response to that violence. The purpose of this study is to report on a synthesis of Northern Territorial literature and a 3-year media watch conducted in the Canadian territories. This review is part of a multidisciplinary 5-year study occurring in the Northwest Territories (NT) and northern regions of the Prairie Provinces of Canada. The methods included a review of the literature through CINAHL, PubMed, Academic Search Complete, Social Sciences Index and JSTOR (1990-2012) combined with a media watch from 2009 to 2012. A thematic content analysis was completed. THEMES INCLUDED: colonization; alcohol and substance use; effects of residential schooling; housing inadequacies; help-seeking behaviors; and gaps within the justice system. Identified themes from the media watch were: murders from IPV; reported assaults and criminal charges; emergency protection orders; and awareness campaigns and prevention measures. When synthesized, the results of the literature review and media surveillance depict a starting context and description of IPV in the Canadian territories. There are many questions left unanswered which build support for the necessity of the current research, outline the public outcry for action in local media and identify the current published knowledge about IPV.

    The relationship between economic development and environment and the evolution characteristics of spatial pattern in Hexi Corridor of Northwest China were analyzed based on Landsat images in 1985, 1995, 2000 and 2011 with twenty counties in Hexi Corridor chosen as the basic research units. The ecological economic harmony during 1985-2011 was estimated according to ESV (ecosystem services value) and EEH (ecological and economic harmony) index with the ecosystem services value estimation methods. The results showed that the land type of the study area dramatically changed during the study period, the grassland decreased badly, and the construction land and cultivated land increased quickly. The ESV showed an overall downward trend, especially in the Shiyang River basin and the middle of Heihe River. The ESV in the Shule River basin in this period. After 2000, the economic growth speeded up visibly in the study area. The economic development concentrated in the resource-based cities and regional central cities, and declined from the center of corridor to the both sides. The ecological-economic relation in Hexi Corridor experienced a transformation of "preliminary deterioration--further deterioration--low grade coordination". The EEH had large changes in the Shiyang River basin and the middle of Heihe River, which experienced a transformation of "conflict--more conflicts--less conflicts", however, there was little change in Shule River basin. The development mode and the comprehensive reclamation of Shiyang River basin and Heihe River basin had a significant influence on the regional ecological and economic harmony.

    The U.S. Geological Survey (USGS) has produced a River Reach File data layer for the Pacific Northwest for use in water-resource management applications. The Pacific Northwest (PNW) River Reach Files, a geo-referenced river reach data layer at 1:100,000-scale, are encoded with the U.S. Environmental Protection Agency"s (EPA) reach numbers. The encoding was a primary task of the River Reach project, because EPA"s reach identifiers are also an integral hydrologic component in a regional Northwest Environmental Data Base-an ongoing effort by Federal and State agencies to compile information on reach-specific resources on rivers in Oregon, Idaho, Washington, and western Montana. A unique conflation algorithm was developed by the USGS to transfer the EPA reach codes and other meaningful attributes from the 1:250,000-scale EPA TRACE graphic files to the PNW Reach Files. The PNW Reach Files also were designed so that reach-specific information upstream or downstream from a point in the stream network could be extracted from feature attribute tables or from a Geographic Information System. This report documents the methodology used to create this 1:100,000-scale hydrologic data layer.

    As a consequence of global warming and an enhanced water cycle, the climate changed in northwest China, most notably in the Xinjiang area in the year 1987. Precipitation, glacial melt water and river runoff and air temperature increased continuously during the last decades, as did also the water level of inland lakes and the frequency of flood disasters. As a result, the vegetation cover is improved, number of days with sand-dust storms reduced. From the end of the 19th century to the 1970s, the climate was warm and dry, and then changed to warm and wet. The effects on northwest China can be classified into three classes by using the relation between precipitation and evaporation increase. If precipitation increases more than evaporation, runoff increases and lake water levels rise. We identify regions with: (1) notable change, (2) slight change and (3) no change. The future climate for doubled CO2 concentration is simulated in a nested approach with the regional climate model-RegCM2. The annual temperature will increase by 2.7C and annual precipitation by 25%. The cooling effect of aerosols and natural factors will reduce this increase to 2.0C and 19% of precipitation. As a consequence, annual runoff may increase by more than 10%.

    The Loads and Resources Study is presented in three documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; (2) a technical appendix detailing forecasted Pacific Northwest economic trends and loads, and (3) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. In this loads and resources study, resource availability is compared with a range of forecasted electricity consumption. The forecasted future electricity demands -- firm loads -- are subtracted from the projected capability of existing and {open_quotes}contracted for{close_quotes} resources to determine whether Bonneville Power Administration (BPA) and the region will be surplus or deficit. If resources are greater than loads in any particular year or month, there is a surplus of energy and/or capacity, which BPA can sell to increase revenues. Conversely, if firm loads exceed available resources, there is a deficit of energy and/or capacity, and additional conservation, contract purchases, or generating resources will be needed to meet load growth. The Pacific Northwest Loads and Resources Study analyzes the Pacific Northwest`s projected loads and available generating resources in two parts: (1) the loads and resources of the Federal system, for which BPA is the marketing agency; and (2) the larger Pacific Northwest regional power system, which includes loads and resource in addition to the Federal system. The loads and resources analysis in this study simulates the operation of the power system under the Pacific Northwest Coordination Agreement (PNCA) produced by the Pacific Northwest Coordinating Group. This study presents the Federal system and regional analyses for five load forecasts: high, medium-high, medium, medium-low, and low. This analysis projects the yearly average energy consumption and resource availability for Operating Years (OY) 1994--95 through 2003--04.

    Full Text Available The settlement of the territory of north-eastern Serbia by the representatives of the Coţofeni culture began during the second half of the IV millennium, probably under the pressure of invading tribes from Euroasian steppe. This territory extended over Transylvania, Banat, Oltenia and Muntenia (Map 2. On the territory of Serbia they settled from the Djrerdap gorge up to the Mlava river to the west, and through Kučajske mountains, Bor, Zaječar and further to the south, up to Niš. Aspecific symbiosis occurred on the territory of Serbia between the Coţofeni and the Kostolac cultures. According to the results of the latest project of re-identification, the number of Coţofeni-Kostolac sites and settlements increased to 76. After all the sites were re-identified and georeferenced, with consideration of the surrounding landscape, hydrography, geomorphology of the terrain and the character of the ceramic production finds, we believe that there is a need for re-analyzing specific aspects of the cultural and geographic development not only of settlements, but of the entire Coţofeni-Kostolac cultural phenomenon. In this paper we considered three archaeological sites in the Nišava valley, given that re-identification work over the past several years yielded new information (Bubanj-Staro Selo, Velika Humska čuka and Donja Vrežina. The topography of Coţofeni-Kostolac settlements on the territory of north-eastern Serbia, the Serbian part of the Danube valley and its hinterland, is characterized by diversity of position (location above sea level and landscape placement, types of houses and economic survival. In the 70’s of the last century sites were identified that are located in very inaccessible terrain, which in particular cases has an slope incline of 45°, where the number of such settlements in the meantime increased to nine.

    Full Text Available The reform of state socialism came relatively late to Qinghai Province in the Northwest of the People’s Republic of China. One of Qinghai’s most dynamic groups in the social leadership of reform has been the Salar. The Salar were one of the officially recognized nationalities identified in the People’s Republic of China during the 1950s. A relatively small group of some 100,000 currently live along the upper reaches of the Yellow River, on the borders of Qinghai and Gansu Provinces. The Salar are characterised by their commitment to both Islam and China, and by their belief that they live in permanent exile, though there is considerable uncertainty about their origins. The evidence of recent research in Qinghai suggests the perspective of being Chinese citizens, yet a people in exile, significantly shapes recent Salar social and economic activism.

    A number of uranium mines were operated during the fifties and sixties by mining companies, on behalf of the Commonwealth Government, in the Northern Territory, including the Alligator Rivers Region. As no legislation requiring rehabilitation of mines existed at that time, mining works, tailings dumps and mill facilities were just abandoned at the end of operations. Since Self-Government in 1978, the Northern Territory Government, through the Department of Mines and Energy, has been involved in studies leading to the rehabilitation of these abandoned uranium operations with funds provided by the Commonwealth. The first and most extensive example of this type of rehabilitation was the Rum Jungle Project which was completed in June 1986 at a cost of $18.2 million. The sites of the Rockhole and Moline mills and tailings dumps, worked between 1959 and 1972, are also uranium operations considered for rehabilitation by the Northern Territory Government

    Full Text Available The Citizenship Territories Program, created in 2008 to replace the Rural Areas Program 2003, stands out as the Brazilian territorial development policy. This work aims, from the analysis of the Central Territory Citizenship of Rio Grande do Sul, to identify if the limits and possibilities of implementation of this territory are from public policy or from particularities of the region itself. Were outlined four keys for analytical analysis, which seek to discuss how policy has been implemented and how the notion of territorial development has been appropriated by society. In addition, we seek to present the main limitations for the development of territorial politics. Even if the territory proves an important forum for discussion and mobilization in the region, yet is insufficient to account for the territorial development, since the actions and policies of development for the circumscribed space not fully converge.

    Full Text Available In the context of global criticism on urban sprawl, the questions which arises are: what can we do with the expansion forms already occurred in most part of our cities; can they be fully or partially integrated into the city? But first, which exactly are the common morphological features of urban expansion areas in large European cities, and (by comparison in Romania? The urban form correlated to these „sparwl patterns” and „sprawl mechanisms” shows more then the lack of planning, but a social input in occuping the territory, related with a specific meaning of the landscape. The paper explores the relationship between the five distinct morphological patterns ways of forming in relation to spatial and landscape shapes which they generate, in the territories of sprawl, all illustrated through case studies of Bucharest.

    The discussion of the network city has in recent years been supplemented by an increasing interest in reconsidering the notion of territory. Looking into both geographical and urban design theories, we find examples of a focus on how the networks of the city not only connect them irreversibly...... with sites and systems without any direct physical relation, but also of how this does not necessarily result in complete fragmentation and dissociation between the parts and the surrounding landscapes, as described in network city theory. By relating examples from this literature to a description...... in theory. The concept of The Polymorphic, Multilayered and Networked Urbanised Territory is introduced to grasp the reality experienced in European regions outside the largest and most potent versions of contemporary cities....

    Full Text Available At present a territory is considered as the basis for effective socio-economical development of the region. However, special attention should be paid to the presence of available resources on the territory under consideration, as well as the conditions of their future development. The availability and/or the possibility of creating/upgrading the existing resources encourage today the accumulated potential of the territory. Potential of the area is a set of capabilities and different levels of impact on the total potential of the area and includes such resources as natural, human, investment, innovation, employment, scientific and technological, demographic, urban development, tourism, tax, financial, recreational, marketing, cluster and infrastructure, as well as other kinds of potentials. The prospects for the development of enterprises or their complexes determine the capacities of the territory, the basis of their operation being the location. In this connection it is necessary to consider the basic types of potential undertakings, which the article refer to: marketing, investment, innovation, employment, tax, industrial, economic, resources. For more exact information and accurate prediction each primary resource must include a group of elements. The number of analyzed resources, as well as their elements, is not limited. However an obligatory demand for including the resources or their elements in the list is their exceptional importance for the development of the subject. For efficient operation of enterprises or their complexes in a certain area it is necessary to identify the sources of coordinated development of land and property of the complex, the purpose of which is to obtain maximum benefit from the combination of "territory↔enterprise (s". For this aim we suggest assessing the possibility of long-term development according to the following scenario: establishment of a list of core resources, having impact on businesses

  6. From conservationism to sustainable territorial development

    2009-10-01

    Full Text Available Since the end of the 1960s, the eclosion of a planetary problematics related to the recognition of the “ecological limits of material growth” has mobilized growing attention on the part of scientific communities and public opinion. The systemic concept of eco-development has emerged from this context and been gradually disseminated as a an expression of the radical critique of the economistic ideology underlying industrial-technological “civilization”. Over the course of the 1980s and 1990s, the proliferation of case studies on experiences of local and territorial development in different national contexts has contributed to a deepening of (systemic notions of endogeneity, de-centralization, self-reliance, local autonomy and integrated local productive systems, which have always considered bases of the ecodevelopmentalist position. Against the background of the uncertainties, constraints and opportunities imposed by assymetrical globalization, special attention began to be given to the analysis of the innovative and synergic responses – in terms of socio-economic, socio-cultural and political-institutional reorganization – that have been generated within these spaces. Furthermore, and in a rather paradoxical way, most of the studies linked to a territorial focus give little attention to the treatment of the immense challenges brought about through the elosion of socioenvironmental crisis and the appearance of a vast literature dealing with the connection between environment and development. The present article offers exploratory subsidies that attempt to overcome the aforementioned lacunae, evaluating both the pertinence and general conditions of viability of the sustainable territorial development approach at the current stage of evolution of the Brazilian environmental agenda. Keywords: systemic research, ecological policy, environmental policy, sustainable territorial development.

  7. [The hospital as space and as territory].

    Space is lived individually and collectively and can become a source of existential affectation, especially when the lived experience is modified by disease. The fact that the hospital is also a place of territorialisation can potentiate this affectation, with at times surprising consequences. We aim - based on a reflection about the relationship patients and clinicians establish with the territory of the hospital- to identify some psychological and existential issues at stake with regard to space as a social construction.

  10. Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal.

    Science.gov (United States)

    Mayer, Martin; Zedrosser, Andreas; Rosell, Frank

    2017-06-01

    In territorial, socially monogamous species, the establishment and defense of a territory are an important strategy to maximize individual fitness, but the factors responsible for the duration of territory occupancy are rarely studied, especially in long-lived mammals. A long-term monitoring program in southeast Norway spanning over 18 years allowed us to follow the individual life histories of Eurasian beavers ( Castor fiber ) from adolescence in their natal family group to dispersal and territory establishment until the end of territory occupancy. We investigated whether territory size, resource availability, population density, and dispersal age could explain the duration of territory occupancy, which ranged from 1 to 11 years. The duration of territory occupancy was positively related to dispersal age, suggesting that individuals that delayed dispersal had a competitive advantage due to a larger body mass. This is in support with the maturation hypothesis, which states that an animal should await its physical and behavioral maturation before the acquisition of a territory. Further, we found that individuals that established in medium-sized territories occupied them longer as compared to individuals in small or large territories. This suggests that large territories are more costly to defend due to an increased patrolling effort, and small territories might not have sufficient resources. The lifetime reproductive success ranged from zero to six kits and generally increased with an increasing duration of territory occupancy. Our findings show the importance of holding a territory and demonstrate that dispersal decisions and territory selection have important consequences for the fitness of an individual.

  11. Birth Territory: a theory for midwifery practice.

    Science.gov (United States)

    Fahy, Kathleen M; Parratt, Jenny Anne

    2006-07-01

    The theory of Birth Territory describes, explains and predicts the relationships between the environment of the individual birth room, issues of power and control, and the way the woman experiences labour physiologically and emotionally. The theory was synthesised inductively from empirical data generated by the authors in their roles as midwives and researchers. It takes a critical post-structural feminist perspective and expands on some of the ideas of Michel Foucault. Theory synthesis was also informed by current research about the embodied self and the authors' scholarship in the fields of midwifery, human biology, sociology and psychology. In order to demonstrate the significance of the theory, it is applied to two clinical stories that both occur in hospital but are otherwise different. This analysis supports the central proposition that when midwives use 'midwifery guardianship' to create and maintain the ideal Birth Territory then the woman is most likely to give birth naturally, be satisfied with the experience and adapt with ease in the post-birth period. These benefits together with the reduction in medical interventions also benefit the baby. In addition, a positive Birth Territory is posited to have a broader impact on the woman's partner, family and society in general.

  12. Hydrocarbons in Argentina: networks, territories, integration

    International Nuclear Information System (INIS)

    Carrizo, S.C.

    2003-12-01

    Argentinean hydrocarbons networks have lived a huge reorganizing the structure, after the State reform in the 90's. Activities deregulation and the privatization of YPF and Gas del Estado forced the sector re-concentration, since then dominated by foreign companies, leaded by Repsol YPF. The hydrocarbons federalization contributed to the weakening and un-capitalization loss of wealth of the State. These changes resulted in an increase of the hydrocarbons production allowing to achieve the self-supply. Nevertheless, the expansion of internal networks has not been large enough to ensure the coverage of new requirements. Besides, several infrastructures have been built up to join external markets. National networks are connected to those of near neighboring countries. This integration is an opportunity for the 'South Cone' countries to enhance their potentials. In the country, hydrocarbons territories undergo the reorganizing the structure effects (unemployment, loss of territorial identity, etc). With many difficulties and very different possibilities, those territories, like Comodoro Rivadavia, Ensenada et and Bahia Blanca, look for their re-invention. (author)

  16. The automobile and maps in the integration of the Mexican territory, 1929-1962

    Directory of Open Access Journals (Sweden)

    Héctor Mendoza Vargas

    2015-12-01

    Full Text Available This article examines a new social geography opened by the use of the automobile and maps in the Mexican territory between 1929 and 1962. In this temporary scenery, the construction of roads during a considerable span of the 20th Century has been identified as part of the modernization plan of the revolutionary governments of Mexico. This infrastructure furnished the opportunity of getting to know the wide variety of landscapes of the country as never before. A set of new traveling experiences was offered to the middle class at the same time that such diversity of Mexican landscapes caused different emotions through the “pleasure” of ersonally contemplating the rivers, mountains, trees, vegetation, the sea, the hamlets, towns or cities. A central element of this perspective was occupied by the automobile; its presence in Mexico meant a cultural novelty with deep effects and changes in the Mexican society of the 20th Century. The new technological element worked as a new mechanism that started circulating by the roads to observe the landscape. Because of this, we propose the application of three key concepts of space analysis: the circulation territory, the visual territory and the experience territory. Each one of them represents the many sides of the landscape as one study object, and of geography interest, as described below. The territory of circulation came about when the railroads decline started in the twenties and consolidated in the sixties of the past century. That is why in this section we first place a comparative perspective of the motorization levels through the number of inhabitants per automobile in several Latin-American countries having available ordered historical statistics on the matter. Results show a long construction of the automobile culture in this geographic region; construction that incorporated new communication and evolution forms of social groups.

    1993-12-01

    The Pacific Northwest Case Study is a multi-agency analysis of atmospheric/climatic change impacts on the Pacific Northwest (which includes Washington, Oregon, Idaho, and portions of the Columbia River Basin in Western Montana). The purpose of the case study, which began in fiscal year 1991, was to develop and test analytical tools, as well as to develop an assessment of the effects of climate change on climate-sensitive natural resources of the Pacific Northwest and economic sectors dependent on them. The overall study, jointly funded by the US Department of Energy (DOE) and the US Environmental Protection Agency, was a broad-based, reconnaissance-level study to identify potential climate impacts on agriculture, coastal resources, forest resources, and irrigation in the Pacific Northwest. DOE participated in the reconnaissance study, with responsibility for hydroelectric and water supply issues. While this report briefly discusses a broader array of water issues, attention is mainly focused on three aspects of the water study: (1) the effects of the region`s higher temperatures on the demand for electric power (which in turn puts additional demand on hydroelectric resources of the region); (2) the effects of higher temperatures and changes, both in precipitation amounts and seasonality, on river flows and hydroelectric supply; and (3) the effect of higher temperatures and changed precipitation amounts and seasonality on salmonid resources -- particularly the rearing conditions in tributaries of the Columbia River Basin. Because the meaning of regional climate forecasts is still quite uncertain, most of the preliminary findings are based on sensitivity analyses and historical analog climate scenarios.

    Background. Etiologic agents of childhood bacteremia remain poorly defined in Nigeria. The absence of such data promotes indiscriminate use of antibiotics and delays implementation of appropriate preventive strategies. Methods. We established diagnostic laboratories for bacteremia surveillance at regional sites in central and northwest Nigeria. Acutely ill children aged <5 years with clinically suspected bacteremia were evaluated at rural and urban clinical facilities in the Federal Capital Territory, central region and in Kano, northwest Nigeria. Blood was cultured using the automated Bactec incubator system. Results. Between September 2008 and April 2015, we screened 10 133 children. Clinically significant bacteremia was detected in 609 of 4051 (15%) in the northwest and 457 of 6082 (7.5%) in the central region. Across both regions, Salmonella species account for 24%–59.8% of bacteremias and are the commonest cause of childhood bacteremia, with a predominance of Salmonella enterica serovar Typhi. The prevalence of resistance to ampicillin, chloramphenicol, and cotrimoxazole was 38.11%, with regional differences in susceptibility to different antibiotics but high prevalence of resistance to readily available oral antibiotics. Conclusions. Salmonella Typhi is the leading cause of childhood bacteremia in central Nigeria. Expanded surveillance is planned to define the dynamics of transmission. The high prevalence of multidrug-resistant strains calls for improvement in environmental sanitation in the long term and vaccination in the short term. PMID:26449948

    Full Text Available Bed bugs (Cimex lectularius have been a common problem for humans for at least 3,500 years and in Europe their presence was endemic until the end of World War II, when infestations began to decrease. However, since the beginning of the 21st century new cases of infestations have been reported in developed countries. Many theories have been put forward to explain this change of direction, but none has been scientifically proven. The aim of this study is to provide some reports of bed bug infestations in Northern Italy (Liguria, Piedmont and Aosta valley regions and a brief summary about their identification, clinical significance, bioecology and control. From 2008 to date, 17 bed bug infestations were identified in Northwest Italy. Knowledge about the presence and distribution of bed bugs in Italy is scanty, prior to this work only 2 studies reported the comeback of these arthropods in the Italian territory; further investigations would be necessary to better understand the current situation.

    Full Text Available Integration is one of the main consequences of globalization. Elements of microsystems are growing closer, which brings to the foreground problems of interaction and — in a longer perspective — those of close cooperation between different social systems. The article considers the case of North-West Russia, the only territory having a common border with the EU, in order to examine the issue of Russia using the geographical factor, which Otto von Bismarck called the most powerful and intrinsic factor in history. The significance of this factor increased after the Cold War. It was then when the independent Baltic States became a platform for emergence and recognition of the Baltic Sea region. The author focuses on the social and cultural integrity of the region and considers the traditional Nordic countries and the Baltic Sea states as interrelated components of a single region, different from other European regions in terms of economic interests, as well as its natural and sociocultural landscape.

    The System Operation Review (SOR) is a study and environmental compliance process being used by the three Federal agencies to analyze future operations of the system and river use issues. The goal of the SOR is to achieve a coordinated system operation strategy for the river that better meets the needs of all river users. This technical appendix addresses only the effects of alternative system operating strategies for managing the Columbia River system. The River Operation Simulation Experts (ROSE) work group is comprised of representatives of the Corps, BPA, Reclamation, NMFS, Pacific Northwest Utilities Conference Committee (PNUCC), and Northwest Power Planning Council (NPPC). ROSE was responsible for using computer hydroregulation models to simulate the operation of the river system for all of the alternatives evaluated in screening and full scale analysis in SOR. These models are complex computer programs which sequentially route streamflows through each dam in the system, calculating the streamflows, reservoir elevations, spill, power generation and other information at each project and pertinent locations on the river system. ROSE first reviewed specifications of proposed alternatives to determine whether such alternatives were formulated adequately to be run on hydroregulation models

    The interactions between groundwater and surface water have been significantly affected by human activities in the semi-arid Hailiutu catchment, northwest China. Several methods were used to investigate the spatial and temporal interactions between groundwater and surface water. Isotopic and chemical analyses of water samples determined that groundwater discharges to the Hailiutu River, and mass balance equations were employed to estimate groundwater seepage rates along the river using chemical profiles. The hydrograph separation method was used to estimate temporal variations of groundwater discharges to the river. A numerical groundwater model was constructed to simulate groundwater discharges along the river and to analyze effects of water use in the catchment. The simulated seepage rates along the river compare reasonably well with the seepage estimates derived from a chemical profile in 2012. The impacts of human activities (river-water diversion and groundwater abstraction) on the river discharge were analyzed by calculating the differences between the simulated natural groundwater discharge and the measured river discharge. Water use associated with the Hailiutu River increased from 1986 to 1991, reached its highest level from 1992 to 2000, and decreased from 2001 onwards. The reduction of river discharge might have negative impacts on the riparian ecosystem and the water availability for downstream users. The interactions between groundwater and surface water as well as the consequences of human activities should be taken into account when implementing sustainable water resources management in the Hailiutu catchment.

    The Northwest Indiana Robotic (NIRo) Telescope is a remote, automated observing facility recently built by Purdue University Calumet (PUC) at a site in Lowell, IN, approximately 30 miles from the PUC campus. The recently dedicated observatory will be used for broadband and narrowband optical observations by PUC students and faculty, as well as pre-college students through the implementation of standards-based, middle-school modules developed by PUC astronomers and education faculty. The NIRo observatory and its web portal are the central technical elements of a project to improve astronomy education at Purdue Calumet and, more broadly, to improve science education in middle schools of the surrounding region. The NIRo Telescope is a 0.5-meter (20-inch) Ritchey-Chrétien design on a Paramount ME robotic mount, featuring a seven-position filter wheel (UBVRI, Hα, Clear), Peltier (thermoelectrically) cooled CCD camera with 3056 x 3056, square, 12 μm pixels, and off-axis guiding. It provides a coma-free imaging field of 0.5 degrees square, with a plate scale of 0.6 arcseconds per pixel. The observatory has a wireless internet connection, local weather station which publishes data to an internet weather site, and a suite of CCTV security cameras on an IP-based, networked video server. Control of power to every piece of instrumentation is maintained via internet-accessible power distribution units. The telescope can be controlled on-site, or off-site in an attended fashion via an internet connection, but will be used primarily in an unattended mode of automated observation, where queued observations will be scheduled daily from a database of requests. Completed observational data from queued operation will be stored on a campus-based server, which also runs the web portal and observation database. Partial support for this work was provided by the National Science Foundation's Course, Curriculum, and Laboratory Improvement (CCLI) program under Award No. 0736592.

    Full Text Available Research objectives: The article reads on the settlement on and the economic use of the south Trans-Urals territories by Turkic communities. Research materials: Published and unpublished sources: books of official orders in the Russian state, chronicles, acts, diplomatic documents, archaeological data, etc. Results and novelty of the research: Traditionally, administrative divisions of Ural and Trans-Urals are considered to be a sort of a naturally emerged structure. Having analyzed the sources, we may conclude: the system of counties’ (uyezd division, as introduced by the Russian state, did not consider the allocation of the communities and their economic management mode. Cattle breeding practices of the local Turks determined the specifity of their economic activities. Many Turks’ volosts (ancestral territories were compound and consisted of two parts: the winter part and the summer one. These two parts could be quite long-distance, divided by the Urals and upon being included into the Russian state they were designated to different uyezds. For instance, one part of Tersyak volost was assigned to Verkhoturskiy uyezd and the second – to Tyumensky uyezd; the western part of the Myakotinskaya (Bakatin volost was located in Ufimsky uyezd and the eastern – in Tyumensky uyezd, which was in the lower reach of the Iset and Pyshma rivers. Consequently, by the moment of being merged into the Russian state, the territories indicated below were economically managed by the local Turks: South Trans-Urals and a part of Cis-Urals, including the territories in the upperstreams of the Ufa and Chusovaya rivers, along the Pyshma and Iset rivers, partially the Tura river, and Tobol between the outflows of the Miass and Tura. The given practice arose in the late Middle Ages and was intimately connected with Shibanids’ claims who ruled in Tyumen and Siberian Khanates.

With purpose for these hypothesis correctness clarification the distribution of radionuclides by soil layer depth in the vicinities of militant wells (TK-2 and TK-5), as well as in the case and riverbed of the Berezovka river. There are not data confirm the hypothesis about possible constant radionuclides influent from a 'ditch cavities'. So, the hypothesis of the 'Lira' objects territories radionuclide contamination due to inert gases yield on the surface is a more rightful

    Full Text Available The article promotes an approach to assess the prospects of regional development on the basis of the synthesis of comparative and historical methods of research. According to the authors, the comparative analysis of the similar functioning of the socio-economic systems forms deeper understanding what part factors and methods of state regulation play in regional development, and also their place in socio-economic and geopolitical space. The object of the research is Kamchatka territory as the region playing strategically important role in socio-economic development of Russia and also northern territories of the other countries comparable with Kamchatka on the bass if environmental conditions such as Iceland, Greenland, USA (Alaska, Canada (Yukon, and Japan (Hokkaido. On the basis of allocation of the general signs of regional socio-economic systems and creation of the regional development models forming the basis for comparative estimates, the article analyses the territories, which are comparable on the base of climatic, geographic, economic, geopolitical conditions, but thus significantly different due to the level of economic familiarity. The generalization of the extensive statistical material characterizing various spheres of activity at these territories, including branch structure of the economy, its infrastructure security, demographic situation, the budgetary and financial sphere are given. It allows defining the crucial features of the regional economy development models. In the conclusion, the authors emphasize that ignoring of the essential relations among the regional system elements and internal and external factors deprives a research of historical and socio-economic basis.

  16. Territorial expansion and primary state formation.

    2010-04-20

    A major research problem in anthropology is the origin of the state and its bureaucratic form of governance. Of particular importance for evaluating theories of state origins are cases of primary state formation, whereby a first-generation state evolves without contact with any preexisting states. A general model of this process, the territorial-expansion model, is presented and assessed with archaeological data from six areas where primary states emerged in antiquity: Mesoamerica, Peru, Egypt, Mesopotamia, the Indus Valley, and China. In each case, the evidence shows a close correspondence in time between the first appearance of state institutions and the earliest expansion of the state's political-economic control to regions lying more than a day's round-trip from the capital. Although additional research will add detail and clarity to the empirical record, the results to date are consistent with the territorial-expansion model, which argues that the success of such long-distance expansion not only demanded the bureaucratization of central authority but also helped provide the resources necessary to underwrite this administrative transformation.

    Full Text Available This paper discusses the importance of aesthetic inventions on modes of youth subjectivity in the vulnerability and violence contexts. It also intends to reflect on how the actions undertaken by these youth can cut across the discussion between occupational therapy and culture. Therefore, we worked with some fragments of life stories of three young people engaged in cultural collective distinctive - marginal literature soiree, hip hop movement and audiovisual production - in the districts of Brasilândia and Vila Nova Cachoeirinha in the north of the city of São Paulo, whose we could follow through ethnographic incursions in protagonized cultural activities or in which they participate and oral history interviews. The youth subjectivities productions has been configured as a live territory marked not only by poverty and violence experiences, but, also by collective and creative productions, a brand new life style through aesthetic inventions in the periphery where the stigma of being young, negro and poor gives place to an emblem: the pride of being from the periphery. This emblematic territory is highlighted in cultural collective, particularly in Sarau Poetry Brasa and Cinescadão, two strategies of art and culture that invoke an experience resistance, transforming the experiences of violence and vulnerability that are experienced on the outskirts, in ethical, aesthetic and policies practices.

    The article is about the environmental aspects in the territorial classification, of the constitutional structure and its reaches, of the precision in the approaches and procedures and of the law 388 of 1997 it understands each other for the environmental thing the relationship between the systems and natural processes and the systems and social, economic and cultural processes; this way the environmental thing transcends the ecological thing and the geographical thing to become a new dimension of the science, of the knowledge and of the culture. The environmental thing also acquires a particular concretion when serving like basic instrument for the interpretation of the necessities of the society and in the way of satisfying them without damage of the natural thing and territorial classification as the process of reflection of a society on the form of occupying the space, of taking advantage of the natural resources, of building establishments, of establishing an infrastructure and of managing the relationships and the economic flows, to obtain a disposition and space arrangements of their activities finally, in harmony with the nature that they correspond to their culture and the form like it wants to maintain or to improve their quality of life in a sustainable way

  19. Living the territoriality: Mapuche tourism and development

    Full Text Available This article examines how Mapuche entrepreneurs are shaping the landscape of tourism in southern Chile in the context of indigenous development. Based on ethnographic research in and around Lican Ray, we looked at the impacts of Mapuche tourism ventures on development and deterritorialisation. Furthermore, we consider Mapuche tourism as a strategy of resistance in response to the deepening displacement of Mapuche population and the loss of traditional cultural values. The first section means to give an overview of the complexity of issues regarding (indigenous tourism and development as well as to introduce Mapuche tourism practices. Next, dealing with notions as territoriality and collectivism, we argue that Mapuche entrepreneurs are reappropriating Mapuche culture for development. Mapuche tourism is mobilising alternative ways for development, being and relating to the profound relationship they have with their territory and environment in accordance to their worldview. Finally, following the theories of anthropologists Charles Hale and James Scott, we show how Mapuche tourism is shaped in globalisation through Chile’s neoliberal policy. However, the Mapuche indigenous people active in tourism demonstrate that they possess the agency to construct strategies of ‘cultural resistance’. This article brings new perspectives to the study of indigenous tourism and development and represents Mapuche tourism as an opportunity for both indigenous development and resistance.

  15. Energetic cost of feeding territories in an Hawaiian honeycreeper.

    Science.gov (United States)

    Carpenter, F Lynn; MacMillen, Richard E

    1976-09-01

    By analysis of time budgets the daily energy expenditure in territorial individuals of a Hawaiian honeycreeper (Vestiaria coccinea, Fam. Drepanididae) were estimated during the nonbreeding season and compared to that of nonterritorial individuals. The mean rise in living costs was 2.3 kcal/24 h or 17% of the nonterritorial energy budget. The most costly territorial behavior was advertisement rather than chasing, and total territorial cost was seen to be little affected by the number of intruders or the size of the territory. These results are compared with data on feeding (nonbreeding) territories of other nectar-feeding birds. The suggestion is made that hummingbirds may be more likely to develop nonbreeding territorial behavior in any set of environmental circumstances than are honeycreepers because of relatively lower total cost of advertisement plus chasing.

    2015-01-01

    In 2015, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program is assessing stream quality in the Pacific Northwest. The goals of the Pacific Northwest Stream Quality Assessment (Pacific Northwest study) are to assess the quality of streams in the region by characterizing multiple water-quality factors that are stressors to aquatic life and to evaluate the relation between these stressors and biological communities. The effects of urbanization and agriculture on stream quality for the Puget Lowlands and Willamette Valley are the focus of this regional study. Findings will provide the public and policymakers with information regarding which human and environmental factors are the most critical in affecting stream quality and, thus, provide insights about possible approaches to protect or improve the health of streams in the region.

  1. Influence of climate change and human activity on water resources in arid region of Northwest China: An overview

    2017-12-01

    Full Text Available This study reviews the latest progress in research on climate change and water resources in the arid region of Northwest China, analyzes the cause of water resource changes within the region from the perspective of climate change and human activities, and summarizes future likely changes in water resources and associated adaptation strategies. The research shows that the climate in the region has experienced warming and wetting with the most significant warming in winter and the highest increase in summer precipitation since 1961. Areas with the most significant warming trends include the Qaidam Basin, the Yili River Valley, and Tacheng. Spatially, the increasing trend in precipitation becomes increasingly significant from the southeast to the northwest, and northern Xinjiang experienced the highest increase. Studies have shown a decrease in headwater of Shiyang River because runoff is mainly based on precipitation which shows a decrease trend. But an increase in western rivers was observed such as Tarim River and Shule River as well as Heihe River due to rapid glacier shrinkage and snowmelt as well as precipitation increase in mountain area. Meanwhile unreasonable human activities resulted in decrease of runoff in the middle and lower reaches of Haihe River, Shiyang River and Kaidu River. Finally, recommendations for future studies are suggested that include characteristics of changes in extreme weather events and their impacts on water resources, projections of future climate and water resource changes, climate change attribution, the selection of adaptation strategies relating to climate change and social economic activities, and use of scientific methods to quantitatively determine water resource allocation.

    Full Text Available As a result of the cumulative interaction of political, ethnic, demographic, economic, social, biological and other ties, processes and relationships the structure of modern landscapes was formed. Aggregate settlement the Krasnodar region, especially large and medium, together with the lines of communication between them forms a supporting framework of the settlement. Determination of anthropogenic loads on individual components of nature and also on the natural complexes in general, is a central part in assessing the contemporary geo-ecological situation of the area. Within the boundaries of the Northwest Ciscaucasia rural residential landscape occupies 99% of the residential landscape. Agricultural zoning based on landscape approaches is one of the main directions of the transition to sustainable agriculture, which focuses on the combination of high productivity and environmental sustainability of the agrogeosistems. The optimal existence of the landscapes requires that their functions are consistent with their natural properties, resource potential. Complex process of impacts on the landscape extends as chain reactions on the vertical and horizontal landscape relations. On this territory, there is a significant recreational potential. Territory can be used for weekend tours for urban residents, who are located quite close to these recreational richest places. Development of the agro-tourism is the most effective if the industry is evolving as a support towards the main tourist or agricultural specialization.DOI: http://dx.doi.org/10.12731/2218-7405-2014-4-6

    Full Text Available Abstract Background Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory. The internal organization of these chromosome territories is still largely unknown. Results We compared the large-scale chromatin structure of chromosome territories between several hematopoietic chicken cell types at various differentiation stages. Chromosome territories were labeled by fluorescence in situ hybridization in structurally preserved nuclei, recorded by confocal microscopy and evaluated visually and by quantitative image analysis. Chromosome territories in multipotent myeloid precursor cells appeared homogeneously stained and compact. The inactive lysozyme gene as well as the centromere of the lysozyme gene harboring chromosome located to the interior of the chromosome territory. In further differentiated cell types such as myeloblasts, macrophages and erythroblasts chromosome territories appeared increasingly diffuse, disaggregating to separable substructures. The lysozyme gene, which is gradually activated during the differentiation to activated macrophages, as well as the centromere were relocated increasingly to more external positions. Conclusions Our results reveal a cell type specific constitution of chromosome territories. The data suggest that a repositioning of chromosomal loci during differentiation may be a consequence of general changes in chromosome territory morphology, not necessarily related to transcriptional changes.

    Full Text Available Of late, there have been several political, practical and analytical changes to our understanding of rural development. Diverse efforts have emerged in the analysis and discussion of spatial dynamics such as “rurality”, territories, in the construction of a territorial perspective of rural development. These changes in the forms of identification and measurement of rural development lead us to question the validity and effectiveness of applied methods, inviting us to establish methodologies and analytical criteria coherent with the multiple manifestations and scales of development. This article offers a multidimensional and multi-scalar analytical model for territorial rural development, using our methodology tested in four rural territories of Brazil.

    Full Text Available In the context of transforming a part of Serbian anthropology into social theoretic management of identity, I suggest both comparative historiographic and ethnographic learning from societies with similar post-colonial experience, with the aim to include the discipline into an urgent defense of Serbia and Belgrade from further ethno-profiteering interests of elites in/from outer territories, left over on the ruins of our ill judged, resource incompatible, exaggerated or immoral twentieth century adventures. Serbian anthropology, written by anthropologists to whom Serbia and Belgrade are "homeland" by origin or civilized choice, should play the key role in the defense of Serbian citizens from the interest of elites in/from the outer "homelands", particularly by revealing the processes for which it is, as a discipline, most expert at – the professionalization of ethnicity, interactive and hybrid nature of identity, instrumental nature of tradition and the identity politics in general. Having in mind the latest attempt, a particularly successful one, conducted by the end of the 20th and the beginning of the 21st century that the lives, health, well-being, dignity and future of persons born in and loyal to the interest of Serbia and Belgrade, in large scale, thoroughly and long term be sacrificed and dedicated to the interests of ethno-profiteering elites in/from outer territories, in this article I point to the possibility to, along with the comparative learning from the above mentioned post-colonial experiences, delicate experiences of urgent anthropology be applied as well as the rich tradition of collective research. This text analyzes the results of first such research, that represenst the initial, praiseworthy and a brave step in the wise striving to engage social sciences and humanities in a search of expert and not mythical/daily-political solutions of the key problem of the Serbian nation – that of how to settle the interests of the

    The height and extent of billowing smoke plumes from bushfires near Canberra, the Australian capital, are illustrated by these views from the Multi-angle Imaging SpectroRadiometer (MISR). The images were acquired on January 18, 2003. Never before had fires of this magnitude come so close to Australia's capital. Four people lost their lives and over 500 homes were destroyed, mostly in the southwestern suburbs. Australia's famous Mount Stromlo Observatory, located immediately west of the city, was also incinerated by the fires.The top panel portrays a natural-color view from MISR's nadir camera, in which the eastern portion of the Australian Capital Territory is located south of a pale, ephemeral lake in the upper left-hand corner (Lake George). Several smoke plumes originate within the eastern part of the Australian Capital Territory, while the major plumes originate to the west of the image area. The Australian Capital Territory and much of New South Wales are completely obscured by the smoke, which is driven by fierce westerly winds and extends eastward to the coast and over the Pacific Ocean.The lower panel provides a stereoscopically retrieved height field of the clouds and smoke plumes. The greenish areas indicate where smoke plumes extend several kilometers above a bank of patchy stratus clouds below. A few high clouds appear near the bottom of the image. Wind retrievals were excluded from this image in order to generate a smooth and continuous field. Although relative height variations are well-represented here, the inclusion of wind retrievals for this scene reduces the actual cloud height results by 1 to 2 kilometers. Areas where heights could not be retrieved are shown as dark gray.The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuouslyand every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during Terra orbit 16421. The

    The level of Kluane Lake, the largest lake in Yukon Territory, was lower than at present during most of the Holocene. The lake rose rapidly in the late seventeenth century to a level 12 m above present, drowning forest and stranding driftwood on a conspicuous high-stand beach, remnants of which are preserved at the south end of the lake. Kluane Lake fell back to near its present level by the end of the eighteenth century and has fluctuated within a range of about 3 m over the last 50 yr. The primary control on historic fluctuations in lake level is the discharge of Slims River, the largest source of water to the lake. We use tree ring and radiocarbon ages, stratigraphy and sub-bottom acoustic data to evaluate two explanations for the dramatic changes in the level of Kluane Lake. Our data support the hypothesis of Hugh Bostock, who suggested in 1969 that the maximum Little Ice Age advance of Kaskawulsh Glacier deposited large amounts of sediment in the Slims River valley and established the present course of Slims River into Kluane Lake. Bostock argued that these events caused the lake to rise and eventually overflow to the north. The overflowing waters incised the Duke River fan at the north end of Kluane Lake and lowered the lake to its present level. This study highlights the potentially dramatic impacts of climate change on regional hydrology during the Little Ice Age in glacierised mountains.

  10. 2011 Annual Ecological Survey: Pacific Northwest National Laboratory Site

    Energy Technology Data Exchange (ETDEWEB)

    2012-02-27

    The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL site comply with applicable laws, policies, and DOE Orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental setting of the PNNL site is described in Larson and Downs (2009). There are currently two facilities on the PNNL site: the William R. Wiley Environmental Molecular Sciences Laboratory and the Physical Sciences Facility. This report describes the annual survey of biological resources found on the undeveloped upland portions of the PNNL site. The annual survey is comprised of a series of individual field surveys conducted on various days in late May and throughout June 2011. A brief description of the methods PNNL ecologists used to conduct the baseline surveys and a summary of the results of the surveys are presented. Appendix A provides a list of plant and animal species identified in the

    son una prueba del papel de los territorios en su sistema de representación legislativa. Los sistemas bicamerales permiten hacer frente al dilema de la representación democrática cuando los territorios, además de los ciudadanos, importan. En este trabajo, se explora la tensión normativa entre el principio 'una persona, un voto' de representación y el principio de representación de igualdad territorial existente (no sólo en los sistemas federales. Además, se presenta un análisis de los sistemas de representación bicameral conforme a estos dos criterios. Salvo excepciones (por ejemplo, Kymlica, 1996, la mayoría de la literatura previa, de una forma u otra ha juzgado patológica la existencia de criterios territoriales. En este trabajo se discute esa apreciación.

  15. Territorial disputes in international arbitration practice

    Full Text Available This paper deals with the issue of territorial disputes settlement in international arbitrations. The arbitration represents an efficient way of determining state borders, together with diplomatic means of dispute resolution and procedure before the International Court of Justice. Parties in a dispute choose arbiters, rules of procedure and commit themselves to accept and implement arbitration award, which is based on international law. States can create an ad hoc tribunal or they can decide to resolve the dispute before the Permanent Court of Arbitration in The Hague. In arbitration practice there were cases of successful arbitrations, especially in situations when a dispute was primarily factual and when major economic and political interests were not involved.

    Full Text Available The expansión of the agricultural frontier in the Argentine pampas implied a re-valuation of "bordering" spaces, which were considered "marginal" by capital. This paper aims at interpreting the socio-territorial impact -from both a material and a symbolic level- being caused by the expansión of the productive, business-profile [agricultural and oil] frontier in the center-west of the province of La Pampa. With the interpretative approach provided by qualitative methodologies, we intend to analyze -in a case study- how these frontier expansión processes altered and re-defined the social arena between the years 2000 and 2010, the social construction of the space and the power relations in Chos Malal

    2014-01-01

    We report three cases of lymphocutaneous infection caused by the thermally dimorphic fungus, Sporothrix schenckii from Australia's tropical Northern Territory. Two cases were acquired locally, making them the first to be reported from this region. All three cases presented with ulceration in the limb; however, the classical sporotrichoid spread was present only in the first two cases. Their occurrence within several weeks of each other was suggestive of a common source of environmental contamination such as hay used as garden mulch. Diagnoses were delayed in each case, with each patient having substantial exposure to ineffective antibiotics before the correct diagnosis was made. These cases bring the total number of reported sporotrichosis cases in Australia since 1951 to 199. Lessons from these cases are to consider the diagnosis of sporotrichosis in lesions of typical appearance, even in geographical settings from where this pathogen has not previously been reported.

    2014-06-01

    Full Text Available This paper describes an innovative solution for geovisualization of the demographic and administrative history of French municipalities, named "communes" in French. This solution allows for the open dissemination of such data. The challenge is to provide a web interface for unskilled users in order to help them understand complex information about the demographic evolution of French territories. Our approach combines interactive thematic, spatial, and temporal views. We describe our architecture, based on open-source technologies, and the organization of this imperfect geo-historical information in our spatiotemporal database. Our second contribution concerns the concept of an acquaintance graph that has been used to obtain an efficient design with good performance in our geovisualization website.

  19. Simulation of Demographic Change in Palestinian Territories

    Science.gov (United States)

    Sumour, M. A.; El-Astal, A. H.; Shabat, M. M.; Radwan, M. A.

    Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertility rates, leading to a significant increase in population growth. In many poor countries like Palestinian Territories the number of births has fallen and the life expectancy increased. In this paper we concentrate on measuring, analyzing and extrapolating the age structure in Palestine a few decades ago into the future. A Fortran program has been designed and used for the simulation and analysis of our statistical data. This study of demographic change in Palestine has shown that Palestinians will have in future problems as the strongest age cohorts are the above-60-year olds. We therefore recommend the increase of both the retirement age and female employment.

    The first part of this report proposes an overview of the present situation for climate-energy policies in France. It outlines the lack of transversality of local climate-energy policies which tend to be rather sector-oriented, the lack of coherence of these policies, their lack of efficiency due to a weak power of decision of local communities and to their lack of financial means, and the fact that the territorial organisation is not well adapted to climate-energy stakes. The second part presents and comments a set of proposals: to strengthen the region and the inter-communal levels, to give to local communities political and legal means of action, to reinforce human and financial means dedicated to energy transition, and to strengthen survey, follow-up and assessment missions

    International Nuclear Information System (INIS)

    1993-05-01

    This paper reviews the historical evolution of environmental awareness over the last three decades. The aspects covered include: the growing economic interdependence of nations, the development of new technologies, the internationalization of human rights and the phenomenon of organized trans-nationalism. The paper then develops a framework of territorial development assessment criteria embodying the United Nation's approach towards sustainable growth in which the rights of the human individual to a healthy life in harmony with nature are placed at the forefront of all sustainable growth decision making. Examples of decisional processes during actual hearings to decide on the go-ahead of energy development projects in Italy (a district heating system and a combined cycle gas turbine power plant) are given to evidence optimum ways to have public participation and interaction with government and expert committees take place in line with the United Nation's approach towards development. An important element dealt with is how to optimize the dissemination and use of information

    2016-06-01

    Up until today, Malaysia has used renewable energy technology such as biomass, solar and hydro energy for power generation and co-generation in palm oil industries and also for the generation of electricity, yet, we are still far behind other countries which have started to optimize waves for similar production. Wave power is a renewable energy (RE) transported by ocean waves. It is very eco-friendly and is easily reachable. This paper presents an assessment of wave power potential in Malaysian territorial waters including waters of Sabah and Sarawak. In this research, data from Malaysia Meteorology Department (MetMalaysia) is used and is supported by a satellite imaginary obtained from National Aeronautics and Space Administration (NASA) and Malaysia Remote Sensing Agency (ARSM) within the time range of the year 1992 until 2007. There were two types of analyses conducted which were mask analysis and comparative analysis. Mask analysis of a research area is the analysis conducted to filter restricted and sensitive areas. Meanwhile, comparative analysis is an analysis conducted to determine the most potential area for wave power generation. Four comparative analyses which have been carried out were wave power analysis, comparative analysis of wave energy power with the sea topography, hot-spot area analysis and comparative analysis of wave energy with the wind speed. These four analyses underwent clipping processes using Geographic Information System (GIS) to obtain the final result. At the end of this research, the most suitable area to develop a wave energy converter was found, which is in the waters of Terengganu and Sarawak. Besides that, it was concluded that the average potential energy that can be generated in Malaysian territorial waters is between 2.8kW/m to 8.6kW/m.

    2015-08-01

    Full Text Available Background: Injury is the leading cause of death for young people in Canada. For those living in the northern territories (Yukon, Nunavut, and the Northwest Territories, injury represents an even greater problem, with higher rates of injury for people of all ages in northern areas compared with the rest of Canada; however, no such comparative studies have focussed specifically on non-fatal injury in youth. Objective: To profile and examine injuries and their potential causes among youth in the northern territories as compared with other parts of Canada. Design: Cross-sectional data from the 2009/2010 Health Behaviour in School-aged Children survey (youth aged 11–15 years were examined for the Canadian northern territories and the provinces (n=26,078. Individual survey records were linked to community-level data to profile injuries and then study possible determinants via multilevel regression modelling. Results: The prevalence of injury reported by youth was similar in northern populations and other parts of Canada. There were some minimal differences by injury type: northern youth experienced a greater percentage of neighbourhood (p<0.001 and fighting (p=0.02 injuries; youth in the Canadian provinces had a greater proportion of sport-related injuries (p=0.01. Among northern youth, female sex (RR=0.87, 95% CI 0.81–0.94, average (RR=0.88, 95% CI 0.80–0.97 or above-average affluence (RR=0.84, 95% CI 0.76–0.91, not being drunk in the past 12 months (RR=0.77, 95% CI 0.69–0.85, not riding an all-terrain vehicle (RR=0.81, 95% CI 0.68–0.97 and not having permanent road access (RR=0.89, 95% CI 0.80–0.98 were protective against injury; sport participation increased risk (RR=1.45, 95% CI 1.33–1.59. Conclusions: Patterns of injury were similar across youth from the North and other parts of Canada. Given previous research, this was unexpected. When implementing injury prevention initiatives, individual and community-level risk factors are

  11. Monitoring of bird abundance and distribution at McKinley Bay and Hutchison Bay, Northwest Territories, 1981 to 1993

    Energy Technology Data Exchange (ETDEWEB)

    Cornish, B J; Dickson, D L

    1994-04-01

    McKinley Bay has been identified as a preferred site for a harbor to support oil and gas production in the Beaufort Sea. As the bay is a molting area for several species of diving duck, a study was initiated to monitor the effect of harbor development on birds using the bay. Baseline information on the natural annual fluctuations in the number of birds were collected for nine years at McKinley Bay and eight years at neighboring Hutchinson Bay, an area chosen as the control. The final report of the predevelopment phase of the monitoring study is presented, including results of the 1993 surveys and a summary of results of all years of surveys. There were significantly more diving ducks in McKinley Bay in early August 1990 to 1993, on average, than from 1981 to 1985. No statistically significant change in total diving ducks was noted at Hutchinson Bay. Numbers of species of divers varied substantially between years at the two bays but not to the same degree. Significantly more Pacific loons, red-throated loons, and northern pintails were recorded in the 1990-1993 surveys at McKinley Bay than in earlier surveys. Potential explanations for the large between-year fluctuations in diving duck numbers are discussed. The variations may be due to bird responses to changes in the physical environment or related to the limitations of the aerial survey techniques used. Because of the large natural fluctuations in numbers of molting diving ducks using these bays in early August, it will be difficult to detect future impacts of industrial disturbance, even when sources of survey bias are minimized. It is concluded that aerial surveys of molting diving ducks in the two bays are unsuitable for monitoring the effects of industrial development. 41 refs., 7 figs., 23 tabs.

  12. Formation of albitite-hosted uranium within IOCG systems: the Southern Breccia, Great Bear magmatic zone, Northwest Territories, Canada

    Science.gov (United States)

    Montreuil, Jean-François; Corriveau, Louise; Potter, Eric G.

    2015-03-01

    Uranium and polymetallic U mineralization hosted within brecciated albitites occurs one kilometer south of the magnetite-rich Au-Co-Bi-Cu NICO deposit in the southern Great Bear magmatic zone (GBMZ), Canada. Concentrations up to 1 wt% U are distributed throughout a 3 by 0.5 km albitization corridor defined as the Southern Breccia zone. Two distinct U mineralization events are observed. Primary uraninite precipitated with or without pyrite-chalcopyrite ± molybdenite within magnetite-ilmenite-biotite-K-feldspar-altered breccias during high-temperature potassic-iron alteration. Subsequently, pitchblende precipitated in earthy hematite-specular hematite-chlorite veins associated with a low-temperature iron-magnesium alteration. The uraninite-bearing mineralization postdates sodic (albite) and more localized high-temperature potassic-iron (biotite-magnetite ± K-feldspar) alteration yet predates potassic (K-feldspar), boron (tourmaline) and potassic-iron-magnesium (hematite ± K-feldspar ± chlorite) alteration. The Southern Breccia zone shares attributes of the Valhalla (Australia) and Lagoa Real (Brazil) albitite-hosted U deposits but contains greater iron oxide contents and lower contents of riebeckite and carbonates. Potassium, Ni, and Th are also enriched whereas Zr and Sr are depleted with respect to the aforementioned albitite-hosted U deposits. Field relationships, geochemical signatures and available U-Pb dates on pre-, syn- and post-mineralization intrusions place the development of the Southern Breccia and the NICO deposit as part of a single iron oxide alkali-altered (IOAA) system. In addition, this case example illustrates that albitite-hosted U deposits can form in albitization zones that predate base and precious metal ore zones in a single IOAA system and become traps for U and multiple metals once the tectonic regime favors fluid mixing and oxidation-reduction reactions.

  13. Geological interpretation of an airborne gamma-ray spectrometer survey of the Hearne Lake area, Northwest Territories

    Newton, A.R.; Slaney, V.R.

    1978-01-01

    This study shows how large volumes of airborne data can be displayed in a simple format which provides both mapping and exploration geologists with information not easily obtained from the original data. Eleven lines or part-lines from a gamma-ray survey of the Hearne Lake area were chosen as test lines, and airphotos were used to identify outcrops of each rock type and the distribution of overburden, swamp and water along each line. Geological maps were used to locate the test lines and to provide a listing of the rock types in the area. With this information, it was possible to calculate the average radioelement characteristics of each rock type and to group the rock signatures into a number of rock classes. The techniques described are most usefully applied to those areas where the outcrop is extensive, where some form of geological map already exists, where there are airphotos at scales of 1:30,000 or larger, and where the gamma-ray survey lines are less than 2.5 km apart

  7. Individual quality explains variation in reproductive success better than territory quality in a long-lived territorial raptor.

    Directory of Open Access Journals (Sweden)

    Jabi Zabala

    Full Text Available Evolution by natural selection depends on the relationship between individual traits and fitness. Variation in individual fitness can result from habitat (territory quality and individual variation. Individual quality and specialization can have a deep impact on fitness, yet in most studies on territorial species the quality of territory and individuals are confused. We aimed to determine if variation in breeding success is better explained by territories, individual quality or a combination of both. We analysed the number of fledglings and the breeding quality index (the difference between the number of fledglings of an individual/breeding pair and the average number of fledglings of the monitored territories in the same year as part of a long term (16 years peregrine falcon (Falco peregrinus monitoring program with identification of individuals. Using individual and territory identities as correlates of quality, we built Generalised Linear Models with Mixed effects, in which random factors depicted different hypotheses for sources of variation (territory/individual quality in the reproductive success of unique breeding pairs, males and females, and assessed their performance. Most evidence supported the hypothesis that variation in breeding success is explained by individual identity, particularly male identity, rather than territory. There is also some evidence for inter year variations in the breeding success of females and a territory effect in the case of males. We argue that, in territorial species, individual quality is a major source of variation in breeding success, often masked by territory. Future ecological and conservation studies on habitat use should consider and include the effect of individuals, in order to avoid misleading results.

    Full Text Available Backgound and Purpose: Computerized tomography (CT perfusion (or CTP source images from CT scanners with small detector widths can be used to create a dynamic CT angiogram (CTA similar to digital subtraction angiography (DSA. Because CTP studies use a single intravenous injection, all arterial territories enhance simultaneously, and individual arterial territories [i.e., anterior cerebral artery (ACA, middle cerebral artery (MCA, and posterior cerebral artery (PCA] cannot be delineated. This limits the ability to assess collateral flow patterns on dynamic CTAs. The aim of this study was to devise and test a postprocessing method to selectively color-label the major arterial territories on dynamic CTA. Materials and Methods: We identified 22 acute-stroke patients who underwent CTP on a 320-slice CT scanner within 6 h from symptom onset. For each case, two investigators independently generated an arterial territory map from CTP bolus arrival maps using a semiautomated method. The volumes of the arterial territories were calculated for each map and the average relative difference between these volumes was calculated for each case as a measure of interrater agreement. Arterial territory maps were superimposed on the dynamic CTA to create a vessel-selective dynamic CTA with color-coding of the main arterial territories. Two experts rated the arterial territory maps and the color-coded CTAs for consistency with expected arterial territories on a 3-point scale (excellent, moderate, poor. Results: Arterial territory maps were generated for all 22 patients. The median difference in arterial territory volumes between investigators was 2.2% [interquartile range (IQR 0.6-8.5%]. Based on expert review, the arterial territory maps and the vessel-selective dynamic CTAs showed excellent consistency with the expected arterial territories in 18 of 22 patients, moderate consistency in 2 patients, and poor consistency in another 2 patients.

    Extreme precipitation events are one of the causes of natural hazards, such as floods and landslides, making its investigation so important, and this research aims to contribute to the study of the extreme rainfall patterns in a Portuguese mountainous area. The study area is centred on the Arcos de Valdevez county, located in the northwest region of Portugal, the rainiest of the country, with more than 3000 mm of annual rainfall at the Peneda-Gerês mountain system. This work focus on two main subjects related with the precipitation variability on the study area. First, a statistical analysis of several precipitation parameters is carried out, using daily data from 17 rain-gauges with a complete record for the 1960-1995 period. This approach aims to evaluate the main spatial contrasts regarding different aspects of the rainfall regime, described by ten parameters and indices of precipitation extremes (e.g. mean annual precipitation, the annual frequency of precipitation days, wet spells durations, maximum daily precipitation, maximum of precipitation in 30 days, number of days with rainfall exceeding 100 mm and estimated maximum daily rainfall for a return period of 100 years). The results show that the highest precipitation amounts (from annual to daily scales) and the higher frequency of very abundant rainfall events occur in the Serra da Peneda and Gerês mountains, opposing to the valleys of the Lima, Minho and Vez rivers, with lower precipitation amounts and less frequent heavy storms. The second purpose of this work is to find a method of mapping extreme rainfall in this mountainous region, investigating the complex influence of the relief (e.g. elevation, topography) on the precipitation patterns, as well others geographical variables (e.g. distance from coast, latitude), applying tested geo-statistical techniques (Goovaerts, 2000; Diodato, 2005). Models of linear regression were applied to evaluate the influence of different geographical variables (altitude

  12. Protocol for Monitoring Fish Assemblages in Pacific Northwest National Parks

    2008-01-01

    Rivers and streams that drain from Olympic, Mount Rainier, and North Cascades National Parks are among the most protected corridors in the lower 48 States, and represent some of the largest tracts of contiguous, undisturbed habitat throughout the range of several key fish species of the Pacific Northwest. These watersheds are of high regional importance as freshwater habitat sanctuaries for native fish, where habitat conditions are characterized as having little to no disturbance from development, channelization, impervious surfaces, roads, diversions, or hydroelectric projects. Fishery resources are of high ecological and cultural importance in Pacific Northwest National Parks, and significantly contribute to economically important recreational, commercial, and tribal fisheries. This protocol describes procedures to monitor trends in fish assemblages, fish abundance, and water temperature in eight rivers and five wadeable streams in Olympic National Park during summer months, and is based on 4 years of field testing. Fish assemblages link freshwater, marine, and terrestrial ecosystems. They also serve as focal resources of national parks and are excellent indicators of ecological conditions of rivers and streams. Despite the vital importance of native anadromous and resident fish populations, there is no existing monitoring program for fish assemblages in the North Coast and Cascades Network. Specific monitoring objectives of this protocol are to determine seasonal and annual trends in: (1) fish species composition, (2) timing of migration of adult fish, (3) relative abundance, (4) age and size structure, (5) extent of non-native and hatchery fish, and (6) water temperature. To detect seasonal and annual trends in fish assemblages in reference sites, we rely on repeated and consistent annual sampling at each monitoring site. The general rationale for the repeated sampling of reference sites is to ensure that we account for the high interannual variability in fish

Regions of development 3 (South, 4 (South-West and 8 (Bucharest-Ilfov" elaborated during 2004 – 2006, within the AMTRANS programme funded by the Ministry of Education and Research, coordinated by INCD – URBANPROIECT in partnership with the Institute of Geography of the Romanian Academy and the Qualification in Statistics National Centre. The general objective of the project was sustainable and balanced spatial development of the settlement network and promotion of new relationships between urban and rural. Concretely, the study has produced a model of a polycentric and balanced settlement network according to the European principles. The case study testing and validating this model took place in southern Romania, territory exhibiting acutely the entire range of problems related to the state of the settlement network: profoundly large rural areas, accentuated dynamics of declaring new cities without sufficient evidence, excessive polarization exercised by Bucharest, etc. The paper presents the intervention directions needed to balance in the territory urban poles within the studied area, focusing on the establishment of orientation policies to consolidate the role of each settlement based on the hierarchical level of importance: European, national, regional, and local. The paper also identifies possible functional urban areas: the metropolitan area of Bucharest, areas of potential strategic integration, areas of cooperation between the small and medium-sized cities and the rural regions. Within each of these areas, the paper proposes to establish new relationships between urban and rural based on partnership, involving cooperation and coordination in achieving common goals.The study considers that the poles of development are the key element of proposed model, and their identification, formation, and balanced distribution

    Full Text Available In this article we analyse the evolution in time of extreme temperatures significant for Romania with a focus on absolute extreme temperatures recorded on the overall present teritory. After thoroughly investigating the credible sources we quoted in our bibliography, we present in chronological order the records for absolute minimum temperatures, and absolute maximum temperatures which were measured at the meteorological stations on the present territory of Romania, according to the availability of the data, i.e. the last two decades of the XIXth century up until 2017. We classify and discuss the sources of climatological data in the form of minimum and maximum temperatures. The measurements of meteorological parameters on the current national territory were recorded since 1770 at Iași (cf. Dissescu 1931 and also http://www.meteoromania.ro/anm2/despre-noi/istoric/ - page in Romanian as of 30.03.2017.

This paper argues in favour of the process of global warming (GW and its effects upon the evolution of extreme temperature values in a certain time interval. The conclusions stemming from the investigation of the dataset in this paper should provide a helpful and necessary point of departure in subsequent research of climatologists in their quest of identitifying the correct model of future climate.

    At present, there are 236 measuring points practically homogeneously distributed on the territory of the Czech Republic. 98 measuring points are distributed as local TLD-networks in the surroundings of Czech two nuclear power plants. Both of the TLD-networks are operated by the National Radiation Protection Institute in Prague. The dosimeters hitherto used are the CaSO{sub 4}:Dy-teflon detectors placed in TL-badges and shielded on both sides by energy compensation filters composed of lead and tin. Recently, a new modernization of the measuring system, type of dosimeter and methods of evaluation is under way. From 1996 the Czech Radiation Monitoring Network will be used the TLD system HARSHAW 4000, along with the type 8807 ENVIRONMENTAL DOSIMETER. The dosimeter is composed of four TL-elements - two LiF and two CaF{sub 2}, placed in a plastic badge. In addition, the CaF{sub 2} elements are shielded on both sides by energy compensation filters composed of tantalum and lead. Before the routine use of the new system a testing of the dosimeters was made. The following text summarizes the obtained results (J.K.). 4 tabs.

    The consequences of a stormy winter period (2009/2010) on the shelf and coastal dynamics off Northwest Iberia are analysed by using model results in combination with the set of available observations in the frame of the Iberian Margin Ocean Observatory (RAIA), a cross-border infrastructure among North Portugal and Galicia (Spain). During the study winter, the frequent arrival of weather fronts forced river plumes to flow along the inner shelf in a fast (>1 m s-1) jet-like structure. The buoyant current strongly influenced the outer rías, the name of the estuaries in the region, where a strong decay of surface salinity (15 °C) and salty (>35.9) waters into the rías associated with the Iberian Poleward Current. Finally, some Lagrangian modelling experiments were performed to analyse the transport ability of the plume and the effect that could have had in the biological material trapped on it. The experiments reveal that an overall northward displacement of surface particles will be expected after several alternate wind events.

    Pacific Northwest Laboratory (PNL) is conducting a program to monitor the waste water from PNL-operated research and development facilities on the Hanford Site. The purpose of the program is to collect data to assess administrative controls and to determine whether discharges to the process sewer meet sewer criteria. Samples have been collected on a regular basis from the major PNL facilities on the Hanford Site since March 1994. A broad range of analyses has been performed to determine the primary constituents in the liquid effluent. The sampling program is briefly summarized in the paper. Continuous monitoring of pH, conductivity, and flow also provides data on the liquid effluent streams. In addition to sampling and monitoring, the program is evaluating the dynamics of the waste stream with dye studies and is evaluating the use of newer technologies for potential deployment in future sampling/monitoring efforts. Information collected to date has been valuable in determining sources of constituents that may be higher than the Waste Acceptance Criteria (WAC) for the Treated Effluent Disposal Facility (TEDF). This facility treats the waste streams before discharge to the Columbia River

    Full Text Available The forest fragments or relict forests on the Western slopes of the Andes in northwest Peru and in south-west Ecuador are fragile ecosystems, which were largely continuous at some stage in the past. The importance and uniqueness of these forests as «refuges» and stable habitats roots partly in their complex diversity and their high levels of endemicity. These in turn are the outcome of a complex topography and ecology. In this introductory chapter 12 studies are analysed, which were presented at the Taller sobre Bosques Relictos de la Vertiente Occidental Andina del Norte del Perú y Sur del Ecuador in May 2004 at the X CONABOT, Trujillo-Perú. This helps to consolidate and update our knowledge on these over 20 forests fragments in northern Peru and two previously unknown fragments are presented for the first time: Bosque La Oscurana (Cajamarca and Kañaris (Lambayeque. Some ideas are exposed on the the relationships between the relict forests, how to analyse their dynamics, how to characterize their structure and how their conservation may be achieved. It is proposed that crucial elements in a conservation of these forests are a urgently inventorizing them to demonstrate their high diversity b emphasizing their economic potential with respect to the abundance of phytogenetic ressources c evaluating their role as catchment areas for the rivers which are the primary source of water for agriculture and urban life on the coast.

    Sustainability theories in European Union (EU) development policies are facing significant challenges: it is difficult to transmit context-specific, publicly communicable messages; the recent development policies strengthen the concurrent development paradigm of economic growth and competitiveness; 'climate change' became a more popular environmental integration term than sustainability in the last few years. However, due to the recent crises of the economic growth, there is a great chance to reintroduce a sustainability-based development. A territorial/regional understanding of sustainability can also be an answer for the current challenges, a platform for refreshing the concept with relevant, specific messages that are close to the everyday life. This paper summarises the 'territorial system'-based basic principles of territorial sustainability in a model called AUTHARSIIV (AUTonomy, HARmony, Solidarity, Innovation, Identity and Values). This is a supplementary sustainability content specified for the context of spatial/regional development or planning. The paper also examines the presence of 'general and territorial sustainability' in regional development programmes, and case studies on applying the territorial sustainability principles in planning, assessment, and implementation. According to the results, sustainability is rarely adapted to the conditions of a given sector or a region, and the territorial aspect of sustainability is underrepresented even in territorial programmes. Therefore, the paper proposes a new planning and assessment system that is based on a set of regionally legitimate sustainability values.

  5. Indigenous Territories and REDD in Latin America: Opportunity or Threat?

    Directory of Open Access Journals (Sweden)

    Chris van Dam

    2011-03-01

    Full Text Available An important proportion of Latin America’s forests are located in indigenous territories, and indigenous peoples are the beneficiaries of about 85% of the area for which local rights to land and forest have been recognized in Latin America since the 1980s. Nevertheless, many of these areas, whether or not rights have been recognized, are subject to threats from colonists, illegal loggers, mining and oil interests and others, whose practices endanger not only the forests but also indigenous people’s territory as a whole. In this context, REDD could constitute a new threat or intensify others, particularly in places where indigenous tenure rights have not been recognized, but REDD could also offer new opportunities. This article describes the limitations of thinking only in terms of communities, rather than territories, and examines the extent to which REDD has been conceived considering the characteristics of this new territorial configuration. It also identifies the challenges that REDD may face with this new ‘stakeholder’, such as numerous specific characteristics of territories, given their heterogeneity, in the context of past experiences regarding ‘forest options’. This paper analyses the situation in already-titled indigenous territories in particular, and also discusses problems facing territories in the titling process.

    2017-01-01

    Full Text Available It is often claimed that states have territorial rights, and that these rights include the right to exclude people who seek admission to their territory. In this paper I will examine whether the most defensible account of territorial rights can provide support to the right to exclude. I will discuss three types of theories of territorial rights. The first account links the right of states to exclude to the prior right of individuals to freedom of association, which is said to include the right not to associate and to dissociate. The second is a Lockean theory that grounds the territorial rights of states, and hence their right to exclude, in the prior right of individuals to private property in the land that constitutes the territory of the state. I argue that these accounts have independently implausible implications, regardless of their implications for the immigration debate. The third account is a Kantian theory that bases the territorial jurisdiction of states on individuals’ duty to create, sustain and submit themselves to a shared system of law that is a necessary condition of guaranteeing their rights and of discharging their duties towards one another. I will argue that the Kantian account is superior to its current alternatives. However, I also suggest that it cannot ground a broad right to exclude.

    1991-01-01

    The Pacific Northwest climate is dominated by topography and the Pacific Ocean; the forests have become adapted to the present climate. Within short distances there are large changes in precipitation and temperature, with resultant changes in ecosystems. As the atmospheric concentrations of greenhouse gases increase, global climate is expected to warm and precipitation to increase. Global climate model simulations show enhanced warming at high northern latitudes. For the Pacific Northwest, models show 2-6 degree C warming and increased precipitation in the winter for doubled atmospheric CO 2 concentration. However, the regional details of these models are presently not very reliable. The results and limitations of present global climate models are reviewed. The roles of the oceans, clouds, and other feedback mechanisms are described along with some of the possible impacts of climate change on forest resources. 24 refs., 2 figs., 1 tab

    The goal of this Northwest Power Plan is to preserve and enhance valuable assets by identifying the steps that need to be taken to ensure the lowest cost electrical energy future for the Pacific Northwest. With the 1980's the region entered a new age of electrical power, which poses five major new challenges for the region. (1) All new sources of power are much more expensive than the region's existing hydropower system. (2) The region's industries have divergent needs, and the dilemma is that new additions to the power system will raise costs and threaten the traditional industries. (3) The current surplus of electricity is expensive. Today's surplus is made up of coal and nuclear powered systems which are expensive. (4) The surplus is not evenly shared. High growth metropolitan served by investor-owned utilities with fewer resources compared to demand than the publicly-owned utilities. (5) The surplus could disappear quickly, with high growth the region would need new supplies in the next few years. A 25 year history of the Northwest electrical power development is given

    Artic sea ice loss trends support a greater potential for Arctic shipping. The information of sea ice conditions is important for utilizing Arctic passages. Based on the shipping routes given by ;Arctic Marine Shipping Assessment 2009 Report;, the navigable windows of these routes and the constituent legs were calculated by using sea ice concentration product data from 2006 to 2015, by which a comprehensive knowledge of the sea ice condition of the Northwest Passage was achieved. The results showed that Route 4 (Lancaster Sound - Barrow Strait - Prince Regent Inlet and Bellot Strait - Franklin Strait - Larsen Sound - Victoria Strait - Queen Maud Gulf - Dease Strait - Coronation Gulf - Dolphin and Union Strait - Amundsen Gulf) had the best navigable expectation, Route 2 (Parry Channel - M'Clure Strait) had the worst, and the critical legs affecting the navigation of Northwest Passage were Viscount Melville Sound, Franklin Strait, Victoria Strait, Bellot Strait, M'Clure Strait and Prince of Wales Strait. The shortest navigable period of the routes of Northwest Passage was up to 69 days. The methods used and the results of the study can help the selection and evaluation of Arctic commercial routes.

  16. The public view of Pacific Northwest forests

    International Nuclear Information System (INIS)

    West, P.R.

    1991-01-01

    There are diverse communities that make up the public in the Pacific Northwest, all with differing views on the forest. To the media, the public are those indirect stakeholders, or average citizens, who have become keenly aware of the importance of environmental issues, including the implications for global change. Linkages between the forests, deforestation, global climate change, and overall environmental sustainability have been widely publicized, though less frequently analyzed in depth. Consequently, the state of Northwest forests has become a vital public interest. The need for an overall margin of global environmental security, and a concern over unsuspected consequences of all economic activity (including forestry) have created a community of interest among the urban population. In part, this is a spillover effect from promoting individual environmental responsibility and the conserver ethic into issues beyond the city boundary. In the Northwest, this often translates as a deep concern over forest management issues and strong conviction that changes are needed. At the same time, and largely as a direct response, the socioeconomic interests of rural forest communities have become a high-profile issue, raising debate over local empowerment and local forest stewardship models. The consequences of this complex and rapidly evolving public view of the forests are critical to forest managers and policymakers. 12 refs

    Climate change is one of the key environmental, social and economical issues, and it is also followed by political consequences. Impact of climate conditions on countries' economy is increasingly recognized, and a lot of attention is given, both in the global scale and by the individual national governments. In years 2008-2010, at the Poland -Institute of Meteorology and Water Management-National Research Institute was realized the KLIMAT Project on Impact of climate change on environment, economy and society (changes, effects and methods of reducing them, conclusions for science, engineering practice and economic planning) No. POIG01-03-01-14-011/08. The project was financed by the European Union and Polish state budget in frame of Innovative Economy Operational Programme. A very wide range of research was carried out in the different thematic areas. One of them was "Natural disasters and internal safety of the country (civil and economical)." The problem of drought in Poland was developed in terms of meteorology and hydrology. "Proxy" Data Descriptions very often inform about dry years and seasons, hot periods without precipitation. Analysis of historical material allowed to extract the years that have experienced prolonged periods of high temperatures and rainfall shortages. Weather phenomenon defined as drought belongs to extreme events. This information was very helpful in the process of indexing and thus to restore the course and intensity of climatic elements in the past. The analysis covered the period from year 1000 to modern times. Due to the limited information from the period of 1000-1500 the authors focused primarily on the period from 1500 to 2010. Analysis of the collected material has allowed the development of a highly precise temporal structure of the possible occurrence of dry periods to Polish territory.

    Several research efforts have coordinated the academic program of Agricultural Business Management from the University De La Salle (Bogota D.C., to the design and implementation of a sustainable agribusiness model applied to food development, with territorial projection. Rural development is considered as a process that aims to improve the current capacity and potential of the inhabitant of the sector, which refers not only to production levels and productivity of agricultural items. It takes into account the guidelines of the Organization of the United Nations “Millennium Development Goals” and considered the concept of sustainable food and agriculture development, including food security and nutrition in an integrated interdisciplinary context, with holistic and systemic dimension. Analysis is specified by a model with an emphasis on sustainable agribusiness production chains related to agricultural food items in a specific region. This model was correlated with farm (technical objectives, family (social purposes and community (collective orientations projects. Within this dimension are considered food development concepts and methodologies of Participatory Action Research (PAR. Finally, it addresses the need to link the results to low-income communities, within the concepts of the “new rurality”.

    The climate change impact on water resources is observed in all the Baltic States. These processes became more evident in the last decades. Although the territory of the Baltic States (Lithuania, Latvia, Estonia) is not large (175000 km2), the climatic differences are quite considerable. We performed a regionalization of the territory of the Baltic States depending on the conditions of river runoff formation which can be defined according to percentages of the river feeding sources (precipitation, snowmelt, groundwater). Long-term series of temperature (40 stations), precipitation (59 stations) and river discharge (77 stations) were used to compose ten regional series. This paper addresses: (1) variability in long-term regional series of temperature, precipitation and river discharge over a long period (1922-2007); (2) changes in regional series, comparing the periods 1991-2007 and 1931-1960 with the reference period (1961-1990), and (3) the impact of temperature and precipitation changes on regional river discharge.

    2018-03-01

    In the presented work we consider mire landscapes in the context of temperature monitoring. The mire landscapes in engineering development of the territory are very sensitive to anthropogenic impact that leads to a change in surface conditions, changes in natural succession and, as a rule, to changes in soil temperature and properties, which in turn may develop a complex of hostile geodynamic processes. For this study we used recording systems for field measurement of peat and subsoil temperatures. The measurements were made in two key areas: the territory of the north-taiga landscapes of Western Siberia (the Siberian Ridges), and the territory of the middle-taiga landscapes of Western Siberia (the Ob middle-river lowland). The paper analyses the data obtained from five observation sites (3, 5, 5a, 6 and 8) referred to hydromorphic landscapes. For the territory of the Siberian Ridges the 5-year average soil temperature was 3°C. For the Ob middle-river lowland the 6-year average soil temperature was 4.2°C. The annual soil temperature in the period 2015-2016 for Site 5a (man-disturbed area) was 8.3°C at all depths, which is 3.8°C higher than in a natural bog (Site 5 was a control area).

  2. The south territory; the city limits as recognition in new ways of urban-regional growth between Bogota and the Municipality of Soacha

    Acebedo R, Luis Fernando

    2002-01-01

    The purpose of this paper is to study the context of the great urban developments occurring in the south of Bogota and Soacha, as two towns that form an extremely complex urban, continuum, emerging from the spread of residential areas and diverse productive activities, during five decades. The Tunjuelito River basin-being part of the Savanna's main ecological structure became the foundation for these settlements. To acknowledge the process of urban expansion, taking the river as a natural borderline, allowed us to identify certain social and functionally homogeneous areas that we named the South Territory. Advances in the understanding of the of Colombian cities we the passing and coming into operation of the first generation of the territorial ordering plans, have allowed us to identify, at least, two shortcomings. The first one has to do with an inherent weakness in regional analyses, which to the present day has hindered progress towards a rational distribution of metropolitan territories; the second one has to do with the lack of adequate tools to interpret the so-called peripheral spaces; spaces which, actually, constitute a complex urban and rural system having extraordinary regional impact. The study of the South Territory helps to prove the truth of this hypothesis and suggests new interpretations and ways to approach the problem

    The article highlights the importance of considering the specificities of spaces/territories/ locations of individual and collective life in creating health promotion actions. It explores how this approach has conceptually consolidated respect for territoriality and territorial actions as a principle and an operational health promotion strategy. Based on the literature, the article also points to the need to envision the territory occupied as a locus to put intersetorialities into practice, giving a voice to people who live there, seek to and solve their complex problems, to existing and emerging social networks. It also presents a nationally and internationally validated strategy/method (Bamboo Method) for the development of local health promotion plans, which enables the prioritization of actions by listening to the people and to the managers.

    Full Text Available In this paper we focus on the structure and territorial borders of the Baltic Sea region, and examine the key structural elements of the transnational territorial transport system. In this respect, we clarify some terms used in transport geography. For the first time the transport system gets territorially localized, which allows for a broad range of new studies of transnational transportation in the Baltic Sea area. We also identify the main principles of development and operation of international territorial transport systems and present them taking the Baltic Sea region as an example. Our findings, we hope, will have a great practical application for researchers of transport geography, especially those studying international logistics.

    The Columbia Ricer is one of the greatest natural resources in the western United States. The river and its tributaries touch the lives of nearly every resident of the Northwest-from providing the world-famous Pacific salmon to supplying the clean natural fuel for over 75 percent of the region's electrical generation. Since early in the century, public and private agencies have labored to capture the benefits of this dynamic river. Today, dozens of major water resource projects throughout the region are fed by the waters of the Columbia Basin river system. And through cooperative efforts, the floods that periodically threaten developments near the river can be controlled. This publication presents a detailed explanation of the planning and operation of the multiple-use dams and reservoirs of the Columbia River system. It describes the river system, those who operate and use it, the agreements and policies that guide system operation, and annual planning for multiple-use operation.

    2015-01-01

    Full Text Available The Northern Territory (NT is among the regions in Australia and the world with the highest solar radiation intensities. The NT has many mine sites which consume significant amount of fossil fuel with consequent greenhouse gas (GHG emissions. The environmental concern related to the fossil fuel consumption and availability of immense solar energy resource in the NT open the possibilities for considering the provision of power to the mining sites using proven solar technologies. Concentrating solar power (CSP systems are deemed as the potential alternatives to current fossil fuel based generating systems in mining industry in the NT. The finding is based on consideration of the major factors in determining the feasibility of CSP system installation, with particular reference to the NT mine sites. These are plant design requirements, climatic, environmental, and other requirements, and capital and operating costs. Based on these factors, four mine sites have been identified as having the potential for CSP plants installation. These are McArthur River Mine, Ranger Mine, Northern Territory Gold Mines, and Tanami Operations. Each site could be served by one CSP plant to cater for the needs of mining operation and the local communities.
