Recently, the European Commission adopted a new strategy to halt the loss of biodiversity. Member states are expected to favor a more effective collection and redistribution of European Union (EU) funds under the current Multiannual Financial Framework for 2014-2020. Because of the large spatial variation in the distribution of biodiversity and conservation needs at the continental scale, EU instruments should ensure that countries with higher biodiversity values get more funds and resources for the conservation than other countries. Using linear regressions, we assessed the association between conservation investments and biodiversity values across member states, accounting for a variety of conservation investment indicators, taxonomic groups (including groups of plants, vertebrates, and invertebrates), and indicators of biodiversity value. In general, we found clear overall associations between conservation investments and biodiversity variables. However, some countries received more or less investment than would be expected based on biodiversity values in those countries. We also found that the extensive use of birds as unique indicators of conservation effectiveness may lead to biased decisions. Our results can inform future decisions regarding funding allocation and thus improve distribution of EU conservation funds. © 2017 Society for Conservation Biology.

In conservation planning, the importance of natural variation is often given inadequate consideration. However, ignoring the implications of variation within species may result in conservation strategies that jeopardize, rather than conserve, target species (see Grieg 1979; Turcek 1951; Storfer 1999). Natural variation in the traits of individuals and populations is...

REVIEW: The evolving linkage between conservation science and practice at The Nature Conservancy.

The Nature Conservancy (TNC) was founded by ecologists as a United States land trust to purchase parcels of habitat for the purpose of scientific study. It has evolved into a global organization working in 35 countries 'to conserve the lands and waters on which all life depends'. TNC is now the world 's largest conservation non-governmental organization (NGO), an early adopter of advances in ecological theory and a producer of new science as a result of practising conservation.The Nature Conservancy 's initial scientific innovation was the use of distributional data for rare species and ecological communities to systematically target lands for conservation. This innovation later evolved into a more rigorous approach known as 'Conservation by Design' that contained elements of systematic conservation planning, strategic planning and monitoring and evaluation.The next scientific transition at TNC was a move to landscape-scale projects, motivated by ideas from landscape ecology. Because the scale at which land could be set aside in areas untouched by humans fell far short of the spatial scale demanded by conservation, TNC became involved with best management practices for forestry, grazing, agriculture, hydropower and other land uses.A third scientific innovation at TNC came with the pursuit of multiobjective planning that accounts for economic and resource needs in the same plans that seek to protect biodiversity.The Millennium Ecosystem Assessment prompted TNC to become increasingly concerned with ecosystem services and the material risk to people posed by ecosystem deterioration.Finally, because conservation depends heavily upon negotiation, TNC has recently recruited social scientists, economists and communication experts. One aspect still missing, however, is a solid scientific understanding of thresholds that should be averted. Synthesis and applications . Over its 60-plus year history, scientific advances have informed The Nature Conservancy (TNC) 's actions

Assessment of the Ecosystem Services Capacity in Natural Protected Areas for Biodiversity Conservation

Ronchi, Silvia; Salata, Stefano

2017-10-01

Recently, in Italy, a legislative proposal has been set to reform the role and the functions of natural protected areas promoting their aggregation (or the abolition) pursuing a better efficiency for their administration and economic saving. The system of natural protected areas is composed of different conservation levels: there are the Natural parks, established in the ‘80 by national or regional institution for the safeguard of natural elements, the Natura 2000 -Habitat 92/43/CEE promoted by European Union, with conservation measures for maintaining or restoring habitats and species of Communitarian interest, and the local parks of supra-municipal interest (namely PLIS) created by single municipalities or their aggregation aimed at limiting the soil sealing process. The hierarchical level of protection has determined differences in the management of the areas which leads to various approaches and strategies for biodiversity conservation and integrity. In order to assess strengths and weaknesses of the legislative initiative, the new management framework should be designed, considering the ecosystem characteristics of each natural protected area to define the future opportunities and critics, rather than, in the extreme case, remove the level of protection due to the absence of valuable ecosystem conditions. The paper provides an operative support to better apply the legislative proposal investigating the dynamics that affect all protected areas using the land take process as a major threat to biodiversity conservation in natural zones. The land take process is explored using the Land Use Change analysis (LUCa) as a possible way to determine the impact and the environmental effects of land transitions. LUCa is also useful to determine the loss of protected zones capacity to support Ecosystem Services. Finally, the assessment of the Ecosystem Services Capacity (ESC) index expresses the ability of each LULC to provide ES and, in particular, the Ecological

The main funding instrument for implementing EU policies on nature conservation and supporting environmental and climate action is the LIFE Nature programme, established by the European Commission in 1992. LIFE Nature projects (>1400 awarded) are applied conservation projects in which partnerships between institutions are critical for successful conservation outcomes, yet little is known about the structure of collaborative networks within and between EU countries. The aim of our study is to understand the nature of collaboration in LIFE Nature projects using a novel application of social network theory at two levels: (1) collaboration between countries, and (2) collaboration within countries using six case studies: Western Europe (United Kingdom and Netherlands), Eastern Europe (Romania and Latvia) and Southern Europe (Greece and Portugal). Using data on 1261 projects financed between 1996 and 2013, we found that Italy was the most successful country not only in terms of awarded number of projects, but also in terms of overall influence being by far the most influent country in the European LIFE Nature network, having the highest eigenvector (0.989) and degree centrality (0.177). Another key player in the network is Netherlands, which ensures a fast communication flow with other network members (closeness-0.318) by staying connected with the most active countries. Although Western European countries have higher centrality scores than most of the Eastern European countries, our results showed that overall there is a lower tendency to create partnerships between different organization categories. Also, the comparisons of the six case studies indicates significant differences in regards to the pattern of creating partnerships, providing valuable information on collaboration on EU nature conservation. This study represents a starting point in predicting the formation of future partnerships within LIFE Nature programme, suggesting ways to improve transnational

First steps towards a European atlas of natural radiation: status of the European indoor radon map

International Nuclear Information System (INIS)

Dubois, G.; Bossew, P.; Tollefsen, T.; De Cort, M.

2010-01-01

Within the context of its institutional scientific support to the European Commission, in 2005 the Radioactivity Environmental Monitoring (REM) group at the Joint Research Centre of the European Commission, started to explore the possibility of mapping indoor radon in European houses as a first step towards preparing a European Atlas of Natural Radiations. The main objective of such an atlas is to contribute to familiarizing the public with its naturally radioactive environment. The process of preparing the atlas should also provide the scientific community with a database of information that can be used for further studies and for highlighting regions with elevated levels of natural radiation. This document presents the status of the European indoor radon (Rn) map, first statistical results, and outlines of forthcoming challenges.

Natural Water Retention Measures (NWRM): from Design to Implementation through European Projects

International Nuclear Information System (INIS)

Magdaleno Mas, F.; Dalacamara Andres, G.

2015-01-01

The Centre for Applied Technique Studies (CETA) of CEDEX has been working over the last few years in different European projects related with the design and development of natural water retention measures (NWRM). These are a number of measures, boosted by the Water Unit of the Environment Directorate-General of the European Commission. with close links to green infrastructures, which try to integrate, from a multifunctional approach, different legal and technical requirements aimed at a better adaptation to extreme hydro meteorological events, environmental protection and conservation, and maintenance of ecosystem services. This paper reviews the underpinning foundations of the concept and the mechanisms for designing and implementing NWRM. It also shows the way they can be applied, by presenting different initiatives developed by CETA since 2008 in Navarra (Arga-Aragon rivers system). For fulfilling those works, CETA has collaborated with environmental and hydraulic authorities of Navarra. It has also actively cooperated with research centres, such as the Institute IMDEA Water. specifically in a European project devoted to the diffusion, assessment, and presentation of NWRM within the context of the EU River Basin Districts.

2017-02-01

Manual field surveys for nature conservation management are expensive and time-consuming and could be supplemented and streamlined by using Remote Sensing (RS). RS is critical to meet requirements of existing laws such as the EU Habitats Directive (HabDir) and more importantly to meet future challenges. The full potential of RS has yet to be harnessed as different nomenclatures and procedures hinder interoperability, comparison and provenance. Therefore, automated tools are needed to use RS data to produce comparable, empirical data outputs that lend themselves to data discovery and provenance. These issues are addressed by a novel, semi-automatic ontology-based classification method that uses machine learning algorithms and Web Ontology Language (OWL) ontologies that yields traceable, interoperable and observation-based classification outputs. The method was tested on European Union Nature Information System (EUNIS) grasslands in Rheinland-Palatinate, Germany. The developed methodology is a first step in developing observation-based ontologies in the field of nature conservation. The tests show promising results for the determination of the grassland indicators wetness and alkalinity with an overall accuracy of 85% for alkalinity and 76% for wetness.

The Impact of Nature Experience on Willingness to Support Conservation

Science.gov (United States)

Zaradic, Patricia A.; Pergams, Oliver R. W.; Kareiva, Peter

2009-01-01

We hypothesized that willingness to financially support conservation depends on one's experience with nature. In order to test this hypothesis, we used a novel time-lagged correlation analysis to look at times series data concerning nature participation, and evaluate its relationship with future conservation support (measured as contributions to conservation NGOs). Our results suggest that the type and timing of nature experience may determine future conservation investment. Time spent hiking or backpacking is correlated with increased conservation contributions 11–12 years later. On the other hand, contributions are negatively correlated with past time spent on activities such as public lands visitation or fishing. Our results suggest that each hiker or backpacker translates to $200–$300 annually in future NGO contributions. We project that the recent decline in popularity of hiking and backpacking will negatively impact conservation NGO contributions from approximately 2010–2011 through at least 2018. PMID:19809511

Soil is an integral component of the global environmental system that supports the quality and diversity of terrestrial life on Earth. Therefore, it is vital to consider the processes and impacts of soil degradation on society, especially on the provision of environmental goods and services, including food security and climate change mitigation and adaptation. Scientific societies devoted to Soil Science play significant roles in promoting soil security by advancing scientific knowledge, education and environmental sustainability. The European Society for Soil Conservation (ESSC) was founded in Ghent (Belgium) on 4 November 1988 by a group of 23 researchers from several European countries. It is an interdisciplinary, non-political association with over 500 members in 56 countries. The ESSC produces and distributes a hardcopy Newsletter twice a year and maintains both a website and Facebook page: http://www.soilconservation.eu/ https://www.facebook.com/European-Society-for-Soil-Conservation-ESSC-100528363448094/ The ESSC aims to: • Support research on soil degradation, soil protection and soil and water conservation. • Provide a network for the exchange of knowledge about soil degradation processes and soil conservation research and practises. • Produce publications on major issues relating to soil degradation and soil and water conservation. • Advise regulators and policy-makers on soil issues, especially soil degradation, protection and conservation. The ESSC held its First International Congress in Silsoe (UK) in 1992. Further International Congresses were held in Munich (1996), Valencia (2000), Budapest (2004), Palermo (2007), Thessaloniki (2011) and Moscow (2015). The Eighth International Congress will be held in Lleida (Spain) in June 2017: http://www.consowalleida2017.com/ Interspersed between these international congresses, the ESSC organizes annual international conferences on specific topics. These include Imola, Italy (Biogeochemical Processes at

Information age technology has the potential to change the game for conservation by continuously monitoring the pulse of the natural world. Whether or not it will depends on the ability of the conservation sector to build a community of practice, come together to define key technology challenges and work with a wide variety of partners to create, implement, and sustain solutions. I describe why these steps are necessary, outline the latest developments in the field and offer actionable ways forward for conservation agencies, universities, funding bodies, professional societies, and technology corporations to come together to realize the revolution that computational technologies can bring for biodiversity conservation.

Liberalising the European natural gas market

Mulder, M.

2002-01-01

Europe's natural gas market is changing radically. The several national markets dominated by monopolistic suppliers are integrating into one European market in which production and trade are subject to competition, while transport through the networks will be unbundled and placed under regulatory influence. What will be the consequences of these changes on natural gas prices, supply security and the environment?

Natural gas supply strategies for European energy market actors

International Nuclear Information System (INIS)

Girault, Vincent

2007-06-01

The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

Sips, H.W.; Bakker, L.; Muizelaar, J.; Velthuijsen, J.W.

1991-01-01

The aim of the title study is to evaluate the environmental and economic consequences of additional energy conservation in five Western European countries: the Netherlands, the Federal Republic of Germany, the United Kingdom, France and Italy. In the first part of the study the economic effects of a policy, in which additional energy conservation is realized only for the Netherlands, is calculated. In this report the results are presented. The calculated results of the economic effects of a coordinated energy conservation policy in the abovementioned countries will be published in a separate report. The effects of three policy variants will be evaluated: the non-financial policy variant, the shift of the financial burden variant, and the variant in which the levies are not compensated.The starting point for the first variant is an autonomous realization of the energy conservation. The basis of the second variant is that an equal amount of energy can be saved by means of a substantial energy levy. The profits of this levy can be used to reduce the financial burden of labour. For the economic calculations use has been made of the HERMES-model. Every member of the European Community has developed such a macro-economic model. In chapter two the different starting points for the calculations are outlined, with special attention to descriptions of the policy variants, the model-input and the basic projection. In chapter three the economic effects of the policy variants are presented and discussed. In chapter four the energy conservation and the environmental effects of the variants are dealt with. The most important conclusion of this study is that a considerable amount of energy can be saved, which will have positive effects on the economy and the environment. 8 figs., 20 tabs., 6 apps., 32 refs

The success of European plant species as aliens worldwide is thought to reflect their association with human-disturbed environments. However, an explicit test including all human-made, seminatural and natural habitat types of Europe, and their contributions as donor habitats of naturalized species to the rest of the globe, has been missing. Here we combine two databases, the European Vegetation Checklist and the Global Naturalized Alien Flora, to assess how human influence in European habitats affects the probability of naturalization of their plant species on other continents. A total of 9,875 native European vascular plant species were assigned to 39 European habitat types; of these, 2,550 species have become naturalized somewhere in the world. Species that occur in both human-made habitats and seminatural or natural habitats in Europe have the highest probability of naturalization (64.7% and 64.5% of them have naturalized). Species associated only with human-made or seminatural habitats still have a significantly higher probability of becoming naturalized (41.7% and 28.6%, respectively) than species confined to natural habitats (19.4%). Species associated with arable land and human settlements were recorded as naturalized in the largest number of regions worldwide. Our findings highlight that plant species' association with native-range habitats disturbed by human activities, combined with broad habitat range, play an important role in shaping global patterns of plant invasions.

For a long time, the right of nature conservation and landscape conservation showed a shadowy existence in the approval of projects. Some actual decisions of the Supreme Court show that in the last years the nature conservation law developed to a central area of conflict in the licensing procedure. The contribution under consideration reports on the legal material using three selected problem areas from the law on the protection of area and law on the protection of species. On the one hand, the Federal Administrative Court (Leipzig, Federal Republic of Germany) always upgrades the requirements. However, on the other hand the Federal Administrative Court attaches great importance to practicability. The Federal Administrative Court often points to a way, how projects can be realized with a careful nature conservation related attendance also at difficult environmental conditions.

Theory and Practice in Nature Conservation - Where to Seek Sustainability?

Science.gov (United States)

Mirek, Zbigniew; Witkowski, Zbigniew

2017-12-01

Contemporary nature conservation is the subject of serious disputes, with biocentrists emphasising the superiority of the good of nature, while anthropocentrists believe that conservation space should also take account of the good of humankind. The dispute concerns two very important values perceived differently, and not resolvable within any scientifi c framework. The authors postulate a return to the Christian roots of our civilisation. It was God who gave human beings the goods He had created, expecting them to be used in line with His plan. The man who lost God's plan, destroys the life of nature as well as his own. The postulated solution is the proper shaping of conscience, to condition biodiversity conservation in line with the idea of sustainable development.

The future of European natural gas

International Nuclear Information System (INIS)

Ausems, D.

1991-01-01

Western Europe's natural gas markets abound with opportunities. They also contain major challenges. This paper presents a revealing assessment of both the challenges and the opportunities that arise from those markets. It also explains some of the surprising ways in which the European Commission and Dutch gas industry will influence gas markets throughout the Continent. Gas consumption is well-established and expanding in a small group of European nations. These countries rely on an equally small collection of suppliers, both within and beyond the Community's borders, to provide the required volumes of natural gas. Because supply and demand are likely to grow at significantly different rates, it is suggested what a major market imbalance could materialize before the end of the decade. Averting major gas supply problems beyond the year 2000 will require multi-billion dollar commitments by producers and will necessitate long-term take-or-pay contacts backed by strong and financially healthy buyers

Evaluating whether nature's intrinsic value is an axiom of or anathema to conservation.

Science.gov (United States)

Vucetich, John A; Bruskotter, Jeremy T; Nelson, Michael Paul

2015-04-01

That at least some aspects of nature possess intrinsic value is considered by some an axiom of conservation. Others consider nature's intrinsic value superfluous or anathema. This range of views among mainstream conservation professionals potentially threatens the foundation of conservation. One challenge in resolving this disparity is that disparaging portrayals of nature's intrinsic value appear rooted in misconceptions and unfounded presumptions about what it means to acknowledge nature's intrinsic value. That acknowledgment has been characterized as vacuous, misanthropic, of little practical consequence to conservation, adequately accommodated by economic valuation, and not widely accepted in society. We reviewed the philosophical basis for nature's intrinsic value and the implications for acknowledging that value. Our analysis is rooted to the notion that when something possesses intrinsic value it deserves to be treated with respect for what it is, with concern for its welfare or in a just manner. From this basis, one can only conclude that nature's intrinsic value is not a vacuous concept or adequately accommodated by economic valuation. Acknowledging nature's intrinsic value is not misanthropic because concern for nature's welfare (aside from its influence on human welfare) does not in any way preclude also being concerned for human welfare. The practical import of acknowledging nature's intrinsic value rises from recognizing all the objects of conservation concern (e.g., many endangered species) that offer little benefit to human welfare. Sociological and cultural evidence indicates the belief that at least some elements of nature possess intrinsic value is widespread in society. Our reasoning suggests the appropriateness of rejecting the assertion that nature's intrinsic value is anathema to conservation and accepting its role as an axiom. © 2015 Society for Conservation Biology.

2013-01-01

Full Text Available The paper considers theoretical and applied foundations of the concept of the ecological corridors in nature conservation. Their relevance comes from recent ecological phenomenon of habitat fragmentation which is rapidly increasing during last decades. Habitat fragmentation is one of the main threats to richness and diversity of wildlife. Ecological corridors can mitigate the loss and fragmentation of habitat. Corridors perform as “bridges” between habitats for species and they provide a flow of the natural or even anthropogenic caused disturbances. In this paper we will present the meaning and significance of ecological corridors in nature conservation, as well as types of ecological corridors and their ecological benefits. Methodological and practical approaches in nature protection system in Serbia are included. [Projekat Ministarstva nauke Republike Srbije, br. 47007 i br. 176008

The Impact of Wind Power on European Natural Gas Markets

NONE

2012-09-06

Due to its clean burning properties, low investment costs and flexibility in production, natural gas is often put forward as the ideal partner fuel for wind power and other renewable sources of electricity generation with strongly variable output. This working paper examines three vital questions associated with this premise: 1) Is natural gas indeed the best partner fuel for wind power? 2) If so, to what extent will an increasing market share of wind power in European electricity generation affect demand for natural gas in the power sector? and 3) Considering the existing European natural gas markets, is natural gas capable of fulfilling this role of partner for renewable sources of electricity?.

The European natural gas market

International Nuclear Information System (INIS)

Hagland, Jan

2001-01-01

An increasing amount of natural gas is flowing into continental Europe, one of the largest gas markets in the world. There are three main sources of gas: Africa, Russia and Norway. Norway is an important supplier of gas, but may be vulnerable to competition. The demand for gas is increasing on a global basis and the largest increase is expected in Asia, followed by America and Europe. It is expected that Norwegian gas deliveries will be a principle source of natural gas for North Europe in the next years and that they will take an increasing part of the British market as the gas deliveries from the British shelf is going down. The European gas market is likely to become liberalized according to the EU's competition- and gas directives. This will not necessarily be a problem, and Norway may be able to increase the export of gas to Great Britain considerably from the year 2010, perhaps up to 40 billion standard m3 per year. Russia is expected to take an increased share of the European gas market, especially in East- and Central Europe, Germany and North Italy. But large investments in existing fields, new developments and new strategic pipelines are necessary

The explanatory variables included lagged demand per capita, heating degree days index, real prices of natural gas, light fuel oil, electricity, and real private income per capita. The short-run own-price and income elasticity tend to be very inelastic, but with greater long-run responsiveness. By splitting the data set in two time periods, an increase in the own-price elasticities were detected for the European residential natural gas demand market as a whole. We have provided support for employing a heterogeneous estimator such as the shrinkage estimator. But the empirical results also motivate a further scrutiny of its properties. (Author)

Defining historical baselines for conservation: ecological changes since European settlement on Vancouver Island, Canada.

Conservation and restoration goals are often defined by historical baseline conditions that occurred prior to a particular period of human disturbance, such as European settlement in North America. Nevertheless, if ecosystems were heavily influenced by native peoples prior to European settlement, conservation efforts may require active management rather than simple removal of or reductions in recent forms of disturbance. We used pre-European settlement land survey records (1859-1874) and contemporary vegetation surveys to assess changes over the past 150 years in tree species and habitat composition, forest density, and tree size structure on southern Vancouver Island and Saltspring Island, British Columbia, Canada. Several lines of evidence support the hypothesis that frequent historical burning by native peoples, and subsequent fire suppression, have played dominant roles in shaping this landscape. First, the relative frequency of fire-sensitive species (e.g., cedar [Thuja plicata]) has increased, whereas fire-tolerant species (e.g., Douglas-fir [Pseudotsuga menziesii]) have decreased. Tree density has increased 2-fold, and the proportion of the landscape in forest has greatly increased at the expense of open habitats (plains, savannas), which today contain most of the region's threatened species. Finally, the frequency distribution of tree size has shifted from unimodal to monotonically decreasing, which suggests removal of an important barrier to tree recruitment. In addition, although most of the open habitats are associated with Garry oak (Quercus garryana) at present, most of the open habitats prior to European settlement were associated with Douglas-fir, which suggests that the current focus on Garry oak as a flagship for the many rare species in savannas may be misguided. Overall, our results indicate that the maintenance and restoration of open habitats will require active management and that historical records can provide critical guidance to such

Understanding and managing compliance in the nature conservation context.

Arias, Adrian

2015-04-15

Nature conservation relies largely on peoples' rule adherence. However, noncompliance in the conservation context is common: it is one of the largest illegal activities in the world, degrading societies, economies and the environment. Understanding and managing compliance is key for ensuring effective conservation, nevertheless crucial concepts and tools are scattered in a wide array of literature. Here I review and integrate these concepts and tools in an effort to guide compliance management in the conservation context. First, I address the understanding of compliance by breaking it down into five key questions: who?, what?, when?, where? and why?. A special focus is given to 'why?' because the answer to this question explains the reasons for compliance and noncompliance, providing critical information for management interventions. Second, I review compliance management strategies, from voluntary compliance to coerced compliance. Finally, I suggest a system, initially proposed for tax compliance, to balance these multiple compliance management strategies. This paper differs from others by providing a broad yet practical scope on theory and tools for understanding and managing compliance in the nature conservation context.

NATURE CONSERVATION MOVEMENT IN THE WORLD: ITS HISTORICAL DEVELOPMENT AND PRESENT SITUATION

Directory of Open Access Journals (Sweden)

Oğuz Kurdoğlu

2007-04-01

Full Text Available Although nature conservation is a well recognized topic at present, it is not a new phenomenon. Throughout history, there are numerous examples of efforts made by governments, rulers, or individual land owners to protect certain land areas that possessed unique natural values. While many of these areas were actually isolated as game preserves for hunting, they were also designed to conserve wildlife. The establishment of Yellowstone National Park in 1972 marks the modern concept of a national park as it was designed on a very large protected natural area. Presently, one of the most efficient ways for nature protection is “area conservation approach” that many organizations have been developing various systems and categories about. Unfortunately, in spite of such improvements and the extension of the protected area network, many of these areas are not properly protected and/or managed in some countries. This study summarizes the historical evolution of nature conservation systems and strategies in the world with the related international legislative aspects as well. As it stated in this paper, USA and Europa have a well known history on nature conservation and show great concern in respect to participating to the international convention and arrangements.

Which future for natural gas in the European-Mediterranean area

International Nuclear Information System (INIS)

Giesbert, J.Ch.

1997-01-01

In the Mediterranean sea surrounding countries, energy consumption and in particular natural gas, is growing up. However, this development requires the mobilization of important capitals and the creation of multilateral partnerships. These investments must be realized when southern and eastern Mediterranean countries will change for a market economy and when the energy market in the European Union is liberalizing. This paper describes the situation of the development of natural gas uses in the Maghreb countries (power production, development of cogeneration systems, supply of LPG fuels for domestic uses, development of distribution and transportation systems) and the position of European gas companies with respect to this developing market: investments, risks assessment, European Union warranty, liberalization of gas markets in the Maghreb countries and in the European union.

Bossew, P.; Tollefsen, T.; Cinelli, G.; De Cort, M.; Gruber, V.

2015-01-01

According to the EURATOM (European Atomic Energy Community) Treaty, one of the missions of the Joint Research Centre (JRC) of the European Commission (EC) is to collect, process, evaluate and present data on environmental radioactivity. In 2006, the JRC started the 'European Atlas of Natural Radiation' project, in order to give an overview of the geographic distribution of sources of, and exposures to, natural radiation. As a first task, a map of indoor radon concentration was created, because in most cases this is the most important contribution to exposure, and since it could be expected that data collection would take quite some time, because radon (Rn) surveys are very differently advanced between European countries. The authors show the latest status of this map. A technically more ambitious map proved the one of the geo-genic Rn potential (RP), due to heterogeneity of data sources across Europe and the need to develop models to estimate a harmonised quantity which adequately measures or classifies the RP. Further maps currently in the making include those of secondary cosmic radiation, of terrestrial gamma radiation and of the concentrations of the elements U, Th and K that are its source. In this article, the authors show the progress of some of these maps. (authors)

2013-01-01

We provide the first high-frequency investigation of price discovery within the physical and financial layers of Europe's natural gas markets. Testing not only looks at short-term return dynamics, but also considers each security's contribution to price equilibrium in the longer-term. Results show that UK natural gas futures traded on the Intercontinental Exchange display greater price discovery than physical trading at various hubs throughout Europe. - Highlights: • We use intraday data to gauge price discovery in European natural gas markets. • We explore short and long-term dynamics in physical and financial market layers. • Results show ICE's UK natural gas futures are the main venue for price discovery

Due to the high demand for natural gas from emerging countries and because natural gas has become an increasingly valuable resource is electricity production, natural gas demand should increase. This paper re-examines the geopolitical key issues related to natural gas as well as the uneven distribution of natural gas resources on a worldwide scale. This paper proposes to define the significance of liquefied natural gas in gas exchanges and it analyses the problem of European gas vulnerability using several indicators

Natural Fostering in Fritillaria cirrhosa: Integrating herbal medicine production with biodiversity conservation

Xiwen Li

2012-02-01

Full Text Available Protected areas are generally regarded as a power tool to conserve biodiversity. Nonetheless, few protected areas could address three crucial problems simultaneously, namely funding, public participation and rural living. Here, we introduced a new protective approach, Natural Fostering, which integrated herbal medicine production with community conservation. The principles of Natural Fostering adopted species–species interaction at community level. Most effective chemical components of herbal medicine are derived from such interaction. Fritillaria cirrhosa was selected as an economic botany, one of herbal medicines, to carry out Natural Fostering. Community habitats, herbal medicine production, funding and income of local family were investigated to verify the feasibility of Natural Fostering for biodiversity. We found the density of plant populations and the annual average personal income of rural people increased. F. cirrhosa production could provide sufficient funds for sustainable conservation. Local people gradually changed their life style of wild collection and overgrazing, instead of herbal medicine production. The fostering area set up a good sustainable economic cycle. Natural Fostering can be presented as an effective and pragmatic way to conserve biological diversity and sustainable utilization of traditional medicinal resources.

Children are becoming less likely to have direct contact with nature. This ongoing loss of human interactions with nature, the extinction of experience, is viewed as one of the most fundamental obstacles to addressing global environmental challenges. However, the consequences for biodiversity conservation have been examined very little. Here, we conducted a questionnaire survey of elementary schoolchildren and investigated effects of the frequency of direct (participating in nature-based activities) and vicarious experiences of nature (reading books or watching TV programs about nature and talking about nature with parents or friends) on their affective attitudes (individuals' emotional feelings) toward and willingness to conserve biodiversity. A total of 397 children participated in the surveys in Tokyo. Children's affective attitudes and willingness to conserve biodiversity were positively associated with the frequency of both direct and vicarious experiences of nature. Path analysis showed that effects of direct and vicarious experiences on children's willingness to conserve biodiversity were mediated by their affective attitudes. This study demonstrates that children who frequently experience nature are likely to develop greater emotional affinity to and support for protecting biodiversity. We suggest that children should be encouraged to experience nature and be provided with various types of these experiences.

Captive-breeding and conservation of the European mammal diversity

Directory of Open Access Journals (Sweden)

Spartaco Gippoliti

2004-06-01

Full Text Available Abstract Under the biological species concept, the intraspecific variability and true species richness of Palearctic mammals has often been overlooked, and therefore the need to conserve it. Recovery projects of endangered European mammals in Western Europe rely mainly upon translocation of conspecifics from viable populations in Central or Eastern Europe. From a wildlife management and restoration ecology point of view, many such recovery projects have been successful. However, from a biodiversity perspective it could be argued that they could have failed to protect the original European biodiversity. The increasing evidence of a complex phylogeographic pattern in many European mammals - especially in the Mediterranean region - has led to a reconsideration of the conservation unit and highlights the need for species-specific programmes for assuring the survival of threatened, distinctive populations. Such programs should also include captive breeding. It is therefore suggested that a two-level classification of captive breeding programmes is needed according to the degree of threat of concerned taxa, to maximise available resources without jeopardising in situ conservation. It is proposed to distinguish between a level I captive breeding programmes, which are part of the conservation strategy for seriously threatened taxa and need to be financed by state or federal agencies, and b "prophylactic" level II for vulnerable taxa or populations, and for which funds may be available mainly from the private sector. Available evidence suggests that given adequate husbandry techniques and pre-release training, even captive-bred carnivores can be successfully reintroduced to the wild. However, a closer collaboration among zoological gardens, zoologists and agencies involved in wildlife conservation is needed to avoid ill-conceived, potentially dangerous captive-breeding and re-introduction projects.

Ecology and Ethics: Some Relationships for Nature Conservation

Science.gov (United States)

Abedi-Sarvestani, Ahmad; Shahvali, Mansoor

These days, the reality of environmental crises creates grave doubts about the future of the natural environment. Many believe that if present human behavior toward the natural environment continues, there will be no hope for a sustainable life. Therefore, it is vital that human behavior toward nature be modified and corrected. Although, ethic is traditionally concerned about relations between individuals, but it is getting more attention for modifying human behavior in order to correct human-nature interaction and establish a well-intentioned one. In this respect, we need science of ecology and ethics together. Ecology helps us to understand natural ecosystems and respective regulations and laws, whereas ethics teach us how to define right and wrong behaviors toward the natural environment. This research discusses some possible relationships that might exist between ecology and ethics toward nature conservation.

Balance between climate change mitigation benefits and land use impacts of bioenergy: conservation implications for European birds.

Meller, Laura; Thuiller, Wilfried; Pironon, Samuel; Barbet-Massin, Morgane; Hof, Andries; Cabeza, Mar

2015-07-01

Both climate change and habitat modification exert serious pressure on biodiversity. Although climate change mitigation has been identified as an important strategy for biodiversity conservation, bioenergy remains a controversial mitigation action due to its potential negative ecological and socio-economic impacts which arise through habitat modification by land-use change. While the debate continues, the separate or simultaneous impacts of both climate change and bioenergy on biodiversity have not yet been compared. We assess projected range shifts of 156 European bird species by 2050 under two alternative climate change trajectories: a baseline scenario, where the global mean temperature increases by 4°C by the end of the century, and a 2 degrees scenario, where global concerted effort limits the temperature increase to below 2°C. For the latter scenario, we also quantify the pressure exerted by increased cultivation of energy biomass as modelled by IMAGE2.4, an integrated land-use model. The global bioenergy use in this scenario is in the lower end of the range of previously estimated sustainable potential. Under the assumptions of these scenarios, we find that the magnitude of range shifts due to climate change is far greater than the impact of land conversion to woody bioenergy plantations within the European Union, and that mitigation of climate change reduces the exposure experienced by species. However, we identified potential for local conservation conflict between priority areas for conservation and bioenergy production. These conflicts must be addressed by strict bioenergy sustainability criteria that acknowledge biodiversity conservation needs beyond existing protected areas and apply also to biomass imported from outside the European Union.

Full Text Available Attitude of residing people towards a protected forest area was evaluated for sustainable use of natural resources and forest conservation in the Phu Kao–PhuPhan Kham National Park in Thailand. Their economic and social conditions were assessed in three villages of Phukao, NongBua Lamphu Province. Data were collected from 348 households (66.5% heads or the representatives in the villages with the questionnaire. The questionnaire consisted of three parts: (i general economic and social information (ii social grouping and participation and (iii attitude toward participation in conserving natural resources and tourism management in this area. To evaluate their attitude, the collected data were divided into four categories: (i level 4 equilibrium/nature (ii level 3 warning (iii level 2 risk (iv level 1 crisis for forest conservation in the protected area. Overall, their attitude towards natural resource conservation, the social grouping and the community participation was very low. However, the attitude towards ecotourism is very high. We suggest that forest conservation will be maintained by more progress of ecotourism in this area.

Residential energy-efficient technology adoption, energy conservation, knowledge, and attitudes: An analysis of European countries

International Nuclear Information System (INIS)

Mills, Bradford; Schleich, Joachim

2012-01-01

Relationships between measures of household energy use behavior and household characteristics are estimated using a unique dataset of approximately 5000 households in 10 EU countries and Norway. Family age-composition patterns are found to have a distinct impact on household energy use behavior. Households with young children are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy savings for environmental reasons. By contrast, households with a high share of elderly members place more importance on financial savings, and have lower levels of technology adoption, energy conservation practice use, and knowledge about household energy use. Education levels also matter, with higher levels associated with energy-efficient technology adoption and energy conservation practice use. Similarly, university education increases the stated importance of energy savings for greenhouse gas reductions and decreases the stated importance for financial reasons. Education impacts also vary greatly across survey countries and there is some evidence of an Eastern–Western European divide with respect to attitudes towards energy savings. These cross-country differences highlight the need to balance a common EU energy-efficiency policy framework with flexibility for country specific policies to address unique constraints to energy-efficient technology and conservation practice adoption. - Highlights: ► Household energy use behavior is explored with data from 11 European countries. ► Household age structure and education influence household energy use behavior and attitudes. ► Significant country differences in household energy use behavior exist. ► The EU needs to balance a common energy-efficiency policy framework with country specific policies.

Norwegian Natural Gas. Liberalization of the European Gas Market

International Nuclear Information System (INIS)

Austvik, Ole Gunnar

2003-01-01

Leading abstract. This book focuses on issues that are important for Norway as a major gas exporter and to the development of a liberalized European market. Chapter 2 explains main features of the European gas market. Natural gas is sold in regional markets with independent pricing structure and particularities. In Europe, this has led to large investments for the producers and long-term contracts. The strong market growth and EU's actions to liberalize the market may change this. The organization of the Norwegian gas production and sale is discussed, as well as the reorganization taking place in 2001. Pricing mechanisms are discussed in Chapter 3, both in the ''old'' / existing structure and how a liberalization of the market may change price formation. The increased importance of energy taxation in EU countries is covered in Chapter 4. Even though natural gas is the most environmentally friendly of the fossil fuels, the use of natural gas may be taxed far harder in the future. The report discusses price effects of such a development. Chapter 5 discusses whether or not a gas producer, like Norway, necessarily must earn a resource rent. With the use of economic theory for exhaustible resources it is shown how prices to consumers may increase at the same time as prices to producers drop, where the difference is made up by higher gas taxes to the consuming countries. Transportation of natural gas involves considerable scale advantages and there are often scope advantages from production, storage and sale, as well. Chapter 6 discusses how competition and regulation may influence the functioning and social efficiency of the market, and the concentration of market power. When companies become large, they may exploit market power, supported by the authorities of their respective countries. Chapter 7 focuses on regulatory challenges for the EU, and how the transporters may change between conflicting and cooperation with the EU. Chapter 8 focuses on schedules for

Full Text Available In today’s world, nature conservation and the notion of protected area are of vital importance for the living. Therefore, humankind started to take important steps for conservation of natural areas and preventing deterioration. Nature conservation studies dating back to old times in the world, was put in the agenda in our country after long years. Various protected area status were designated to the areas havin high resources value in our country, and these areas were put under protection by various laws. Some of this conservation status was formed based on the national legislation, and some based on the international conventions. Nowadays, promising actions are taken for sustainable use of biologic diversity and other significant natural resources. In this study; changes and developments in approaches to nature conservation in the world and in our country throughout the history were investigated, and the current situation in Turkey and in the world was revealed.

Increased competition on the supply side of the Western European natural gas market

International Nuclear Information System (INIS)

Golombek, R.; Gjelsvik, E.; Rosendahl, K.E.

1998-01-01

This paper analyzes how the supply side of the Western European natural gas market may react if the demand side becomes competitive. The authors show--using a numerical model of the Western European natural gas market--that once the demand side of the market is liberalized, each gas-producing country has an incentive to break up its gas sellers. The model therefore suggests that there may be numerous producers in a liberalized natural gas market. Hence, in a liberalized market consumers will not be exploited by suppliers

Aligning Natural Resource Conservation and Flood Hazard Mitigation in California.

Calil, Juliano; Beck, Michael W; Gleason, Mary; Merrifield, Matthew; Klausmeyer, Kirk; Newkirk, Sarah

2015-01-01

Flooding is the most common and damaging of all natural disasters in the United States, and was a factor in almost all declared disasters in U.S. Direct flood losses in the U.S. in 2011 totaled $8.41 billion and flood damage has also been on the rise globally over the past century. The National Flood Insurance Program paid out more than $38 billion in claims since its inception in 1968, more than a third of which has gone to the one percent of policies that experienced multiple losses and are classified as "repetitive loss." During the same period, the loss of coastal wetlands and other natural habitat has continued, and funds for conservation and restoration of these habitats are very limited. This study demonstrates that flood losses could be mitigated through action that meets both flood risk reduction and conservation objectives. We found that there are at least 11,243km2 of land in coastal California, which is both flood-prone and has natural resource conservation value, and where a property/structure buyout and habitat restoration project could meet multiple objectives. For example, our results show that in Sonoma County, the extent of land that meets these criteria is 564km2. Further, we explore flood mitigation grant programs that can be a significant source of funds to such projects. We demonstrate that government funded buyouts followed by restoration of targeted lands can support social, environmental, and economic objectives: reduction of flood exposure, restoration of natural resources, and efficient use of limited governmental funds.

Problem for theories with spontaneous CP violation and natural flavor conservation

International Nuclear Information System (INIS)

Sanda, A.I.

1981-01-01

Using a vacuum-saturation approximation, Vainshtein, Zakharov, and Shifman have shown that L = L/sub QCD/+L/sub EW/ can explain the ΔI = 1/2 rule of strange-particle decays. Requiring L/sub EW/ to possess spontaneous CP violation and natural flavor conservation, we estimate epsilon'/epsilon using a similar approximation. We show that a very crude computation results in a very stringent limit 0.050>Vertical Barepsilon'/epsilonVertical Bar>0.048. This estimate is in conflict with the experimental measurement Vertical Barepsilon'/epsilonVertical Bar = 0.003 +- 0.015. This is a problem for theories with spontaneous CP violation and natural flavor conservation if the above understanding of the ΔI = 1/2 rule is correct

The importance of natural-disaster education for social preparedness is presented. Increasing damage caused by natural disasters around the globe draws attention to the fact that even developed societies must adapt to natural processes. Natural-disaster education is a component part of any education strategy for a sustainably oriented society. The purpose of this article is to present the role of formal education in natural disasters in Europe. To ensure a uniform overview, the study used secondary-school geography textbooks from the collection at the Georg Eckert Institute for International Textbook Research in Braunschweig, Germany. Altogether, nearly 190 textbooks from 35 European countries were examined. The greatest focus on natural disasters can be found in textbooks published in western Europe (3.8% of pages describing natural disasters), and the smallest in those published in eastern Europe (0.7%). A share of textbook pages exceeding three percent describing natural disasters can also be found in northern Europe (3.6%) and southeast Europe, including Turkey (3.4%). The shares in central and southern Europe exceed two percent (i.e., 2.8% and 2.3%, respectively). The types and specific examples of natural disasters most commonly covered in textbooks as well as the type of natural disasters presented in textbooks according to the number of casualties and the damage caused were analyzed. The results show that the majority of European (secondary-school) education systems are poorly developed in terms of natural-disaster education. If education is perceived as part of natural-disaster management and governance, greater attention should clearly be dedicated to this activity. In addition to formal education, informal education also raises a series of questions connected with the importance of this type of education. Special attention was drawn to the importance of knowledge that locals have about their region because this aspect of education is important in both

About 60% of the European wetlands are located in the European part of Russia. Nevertheless, data on methane emissions from wetlands of that area are absent. Here we present results of methane emission measurements for two climatically different years from a boreal peatland complex in European Russia. Winter fluxes were well within the range of what has been reported for the peatlands of other boreal regions before, but summer fluxes greatly exceeded the average range of 5–80 mg CH 4 m −2 d −1 for the circumpolar boreal zone. Half of the measured fluxes ranged between 150 and 450 mg CH 4 m −2 d −1 . Extrapolation of our data to the whole boreal zone of European Russia shows that theses emissions could amount to up to 2.7 ± 1.1 Tg CH 4 a −1 , corresponding to 69% of the annual emissions from European wetlands or 33% of the total annual natural European methane emission. In 2008, climatic conditions corresponded to the long term mean, whereas the summer of 2011 was warmer and noticeably drier. Counterintuitively, these conditions led to even higher CH 4 emissions, with peaks up to two times higher than the values measured in 2008. As Russian peatlands dominate the areal extend of wetlands in Europe and are characterized by very high methane fluxes to the atmosphere, it is evident, that sound European methane budgeting will only be achieved with more insight into Russian peatlands.

The Nature and Functions of European Political Borders

Full Text Available The political border limits a state’s territory and symbolizes the extent of a state’s power and ownership. Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

Predominant natural red-shift of quasi-conservative nonlinear systems

2009-01-01

Recent discoveries of nonclassical nonlinear phenomena are attracting a large interest in the scientific community, especially in material science. In spite of this, the natural frequency shift related to the appearance of such phenomena remains partially unclear. In this paper, we apply the general and only recently developed Interaction Box Formalism for investigating if a universality in the natural frequency shift of quasi-conservative nonlinear systems exists. Such universality clearly emerges as a rupture in the symmetry, usually leading to a red-shift, quantifiable as a function of the higher- and sub-harmonic generation.

1996-01-01

Introductory comments on the conference theme and the papers to be presented at this 1995 meeting of SNS Energy were provided. The conference was devoted to 'European Natural Gas Economics', a topic particularly appropriate at this time, in view of the widening of the market as a result of the integration of Central and Eastern European countries following the default of the Soviet Union. Other factors affecting the future of the natural gas market in Europe, such as the recent challenge by Wingas to Ruhrgas' dominance in Germany, the emergence of a spot gas market in the UK, and the threat to prevailing arrangements by the Interconnector, soon to bring gas from the UK to the Continent, were also cited. Papers scheduled for presentation on natural ags supply, on gas prices and gas shares in different sectors of the energy market, on interaction between governments, the EU Commission and the main market actors in shaping the natural gas market, and on the extension of gas use to new geographical regions were briefly characterized

The European Union attempts to harmonise the European natural gas market(s). In general, this is supported on national levels. Nevertheless, such harmonisation is not yet fully accomplished: neither for the rules nor for the quality specifications nor for the physical quantities and their units. Even if the current economic impact of such dis-harmony is negligible, i.e. that market participants for the time being do not have to bear additional costs caused by the lack of harmonisation, participants in the commodity market are exposed to contractual risks. Potentially, this might lead to reduced competition and reduced liquidity of each single and the European internal market for natural gas. However, as the costs for a potential harmonisation of European gas markets are estimated to be significant, the dilemma is evident and the 'political' solution of the 'harmonisation problem' will necessarily deviate from the traders' one.

The potential of military training areas for bird conservation in a central European landscape

European biodiversity has suffered from serious declines during the past few decades, with alterations of land use practices resulting in a loss of fine-scale habitat heterogeneity being a dominant driver. This heterogeneity was maintained by extensive landscape management, which has gradually been replaced by either intensive exploitation or land abandonment. It has been suggested that military training can generate habitat heterogeneity that may support the existence of species of conservation concern, but studies rigorously testing the real importance of military training areas for biodiversity are lacking. Here we address this issue by analyses of two datasets. First, we compared land cover classes between all large military training areas (MTAs) and surrounding control areas (CAs) of the same size in the Czech Republic using multivariate redundancy analysis. We found that the difference in land cover between MTAs and CAs was significant and represented the strongest gradient in land cover classes: from various farmland and artificial habitats typical for CAs to forest and scrubland-grassland mosaic typical for MTAs. Second, we selected one of these areas and compared bird species richness between the MTA and the nearby CA using generalized linear mixed effects models. We found that the number of species of conservation concern was significantly higher in the MTA than in the CA. With respect to habitats, bird species richness was significantly higher in the MTA than in the CA for open habitats, but not for forest habitats. Our results are thus consistent with the view that military training creates areas that are different from the surrounding landscape in terms of land cover, and that this difference translates to a suitability for species of conservation concern. It is remarkable that the positive influence of military training is confined to open habitats, which are subject to the most intensive military activities and also suffer the highest degree of

European sardines are an important fishing resource in the North Atlantic. Recognized for its great commercial and economic value in southern Europe, this resource currently has low stock indices. From this perspective, fishers' local ecological knowledge (LEK) is appreciated as an auxiliary tool in the management of sardines in this region. Our goal is to evaluate the LEK and attitudes towards the conservation of Sardina pilchardus in the typical fishing village of Peniche, Portugal. From June to September 2016, we carried out 87 semi-structured interviews. The four main points of the interviews were interviewee profile, fishing structure, fishermen's LEK and attitudes towards sardine conservation. The interviews were qualitatively and quantitatively analyzed using a 3-point Likert scale. An LEK index and an attitude index were generated. Comparison analyses and correlations were made between the indices and variables of the interviewee profile and the fishing structure. The mean LEK index was 0.55 and was classified as moderate. The attitudes index in relation to conservation was 0.76 and was classified as positive. This index had a positive and significant correlation with the LEK index and a significant negative correlation with the fishermen's age. When the LEK index was compared with the educational level, significant differences were observed only between class A and class C. The result showed that the differences in the attitudes index were statistically significant when the three educational classes were compared. The fishermen of Peniche in Portugal present moderate informal knowledge about the biology and ecology of sardines. Attitudes towards conservation were predominantly positive. Fishermen with greater LEK, with a higher educational level and at a younger age presented more positive attitudes in relation to environmental conservation issues in the present case of the sardine population. The LEK is not necessarily related to the educational level of

The study and practice of conservation biology is inherently interdisciplinary, addresses short and long time-scales and occurs within complex human-natural interfaces. Zoos and aquaria, in partnership with researchers, other non-government organizations, government, industry and educators, are combining knowledge of species and ecosystems with economics, psychology and law to create solutions for conserving biodiversity. From 22 to 25 May, the Conservation Forum of the European Association of Zoos and Aquaria was a venue for discussing conservation research, education and interventions, from the scale of villages to global policy.

There are currently competing demands on Europe's forests and the finite resources and services that they can offer. Forestry intensification that aims at mitigating climate change and biodiversity conservation is one example. Whether or not these two objectives compete can be evaluated by comparative studies of forest landscapes with different histories. We test the hypothesis that indicators of wood production and biodiversity conservation are inversely related in a gradient of long to short forestry intensification histories. Forest management data containing stand age, volume and tree species were used to model the opportunity for wood production and biodiversity conservation in five north European forest regions representing a gradient in landscape history from very long in the West and short in the East. Wood production indicators captured the supply of coniferous wood and total biomass, as well as current accessibility by transport infrastructure. Biodiversity conservation indicators were based on modelling habitat network functionality for focal bird species dependent on different combinations of stand age and tree species composition representing naturally dynamic forests. In each region we randomly sampled 25 individual 100-km 2 areas with contiguous forest cover. Regarding wood production, Sweden's Bergslagen region had the largest areas of coniferous wood, followed by Vitebsk in Belarus and Zemgale in Latvia. NW Russia's case study regions in Pskov and Komi had the lowest values, except for the biomass indicator. The addition of forest accessibility for transportation made the Belarusian and Swedish study region most suitable for wood and biomass production, followed by Latvia and two study regions in NW Russian. Regarding biodiversity conservation, the overall rank among regions was opposite. Mixed and deciduous habitats were functional in Russia, Belarus and Latvia. Old Scots pine and Norway spruce habitats were only functional in Komi. Thus

Conflict and cooperation with respect to European natural-gas regulations

Significant economies of scale and scope in the European gas industry make many transmission and local distribution companies natural monopolies in the markets in which they operate. Often, this gives them a strong market power and they experience little competitive pressure. Hence public interventions into the functioning of the market, as seen under the initiatives taken by the European Commission, such as the 'Gas Directive' occur. This paper discusses a game between the public authority and the transporters, where various levels of conflict and cooperation will influence how far regulations will go and how they will be designed.

Assessment of goods and services, vulnerability, and conservation status of European seabed biotopes: a stepping stone towards ecosystem-based marine spatial management

Directory of Open Access Journals (Sweden)

M. SALOMIDI

2012-02-01

Full Text Available The goal of ecosystem-based marine spatial management is to maintain marine ecosystems in a healthy, productive and resilient condition; hence, they can sustainably provide the needed goods and services for human welfare. However, the increasing pressures upon the marine realm threaten marine ecosystems, especially seabed biotopes, and thus a well-planned approach of managing use of marine space is essential to achieve sustainability. The relative value of seabed biotopes, evaluated on the basis of goods and services, is an important starting point for the spatial management of marine areas. Herein, 56 types of European seabed biotopes and their related goods, services, sensitivity issues, and conservation status were compiled, the latter referring to management and protection tools which currently apply for these biotopes at European or international level. Fishing activities, especially by benthic trawls, and marine pollution are the main threats to European seabed biotopes. Increased seawater turbidity, dredged sediment disposal, coastal constructions, biological invasions, mining, extraction of raw materials, shipping-related activities, tourism, hydrocarbon exploration, and even some practices of scientific research, also exert substantial pressure. Although some first steps have been taken to protect the European sea beds through international agreements and European and national legislation, a finer scale of classification and assessment of marine biotopes is considered crucial in shaping sound priorities and management guidelines towards the effective conservation and sustainability of European marine resources.

The article is devoted to the problem of the conservation of specially protected natural territories. The research topic is especially interesting for urban areas that provide sustainable urban development. The authors consider the main aspects of the sustainable settlement development and substantiate the direct dependence of the evolution of territories in the implementation of urban development activities with the ecological framework of a city. The object of the study is a specially protected natural area located in Western Siberia in the city of Tyumen, the Tyumen region. As a result of the analysis, the main problems of preservation of the nature monument of regional importance were revealed as well as a set of measures and management decisions regarding the conservation of the forest park.

A 2.5-million-year perspective on coarse-filter strategies for conserving nature's stage.

Climate change will require novel conservation strategies. One such tactic is a coarse-filter approach that focuses on conserving nature's stage (CNS) rather than the actors (individual species). However, there is a temporal mismatch between the long-term goals of conservation and the short-term nature of most ecological studies, which leaves many assumptions untested. Paleoecology provides a valuable perspective on coarse-filter strategies by marshaling the natural experiments of the past to contextualize extinction risk due to the emerging impacts of climate change and anthropogenic threats. We reviewed examples from the paleoecological record that highlight the strengths, opportunities, and caveats of a CNS approach. We focused on the near-time geological past of the Quaternary, during which species were subjected to widespread changes in climate and concomitant changes in the physical environment in general. Species experienced a range of individualistic responses to these changes, including community turnover and novel associations, extinction and speciation, range shifts, changes in local richness and evenness, and both equilibrium and disequilibrium responses. Due to the dynamic nature of species responses to Quaternary climate change, a coarse-filter strategy may be appropriate for many taxa because it can accommodate dynamic processes. However, conservationists should also consider that the persistence of landforms varies across space and time, which could have potential long-term consequences for geodiversity and thus biodiversity. © 2015 Society for Conservation Biology.

Position of the American Dietetic Association: dietetics professionals can implement practices to conserve natural resources and protect the environment. (Previously titled "natural resource conservation and waste management").

Science.gov (United States)

2001-10-01

It is the position of the American Dietetic Association to encourage environmentally responsible practices that conserve natural resources, minimize the quantity of waste that is generated, and have the least adverse affect on the health of all living organisms and the environment. All components of the food system, from farmer to consumer, are affected by the availability and cost of energy and the availability and quality of water. Outdoor and indoor air quality significantly impacts the health of all living organisms. Decisions that dietetics professionals make as practitioners and consumers can affect the quantity and type of solid waste generated. The demand for natural resources should be evaluated when selecting the most cost-effective, environmentally sensitive approach to the management of solid waste. Special precautions are needed when using and disposing of hazardous and medical waste to protect the safety of our clients and employees. This position paper provides information and resources for dietetics professionals for addressing the complexity of the environmental issue presented. Conservation strategies are identified that dietetics professionals can use in their worksites and at home. These conservation practices may reduce cost and decrease the environmental impact we have on our communities and the world.

LNG REGASIFICATION TERMINALS ACCESS CAPACITY ANALYSIS FOR SECURITY OF EUROPEAN NATURAL GAS SUPPLY

Directory of Open Access Journals (Sweden)

Matija Veselić

2011-12-01

Full Text Available Increasing natural gas consumption, declining North Sea gas reserves, increased production costs and the deregulation of European gas and electricity markets have all combined to create new opportunities for LNG in Europe. In these circumstances, LNG represents an opportunity for many European countries to diversify their natural gas supply, while decreasing their dependence on Russian natural gas import at the same time. The largest exporters of LNG to Europe are Qatar, Algeria, Nigeria, Trinidad & Tobago, Egypt and Oman. Spain, Great Britain and France are the largest European importers of LNG. Spain has six LNG regasification terminals, followed by four in Great Britain, three in France, two in Italy and Turkey and finally Greece and Portugal with one terminal each. New LNG regasification terminals are currently under construction in Italy, Spain, Sweden and Netherlands. In addition, more than 30 new LNG terminal projects have been proposed around Europe. Italy plans to construct as many as 10 new regasification terminals, due to the strong orientation of its national energy policy towards LNG. Many European countries are strongly considering participating in the LNG chain for the first time, namely Albania, Cyprus, Ireland, Lithuania, Germany, Poland, Romania, Ukraine and Croatia. This paper focuses on a specific aspect of the LNG supply chain: the import facility (the paper is published in Croatian.

NATGAS. A Model of the European Natural Gas Market

International Nuclear Information System (INIS)

Mulder, M; Zwart, G.

2006-02-01

The NATural GAS model is an integrated model of the European wholesale gas market providing long-run projections of supply, transport, storage and consumption patterns in the model region, aggregated in 5-year periods, distinguishing two seasons (winter and summer). Model results include levels of investment in the various branches, output and consumption, depletion of reserves and price levels. The NATGAS model computes long-term effects of policy measures on future gas production and gas prices in Europe. NATGAS is an equilibrium model describing behaviour of gas producers, investors in infrastructure (pipeline, LNG capacity, as well as storage), traders and consumers. NATGAS covers the main European demand regions, including the United Kingdom, Germany, the Netherlands and Italy. Moreover, it covers the main origins of supply on the European market, such as Russia, Norway, Algeria, the Netherlands, the United Kingdom and LNG. In this memorandum, we first discuss the theoretical background as well as the model specifications. Afterwards, we describe the data we used, present some results and assess validity by computing sensitivities and comparing with current developments

Natural gas opportunities, utilization and trades (in a European context)

International Nuclear Information System (INIS)

Corke, M.J.

1996-01-01

The historical development of natural gas consumption in Europe has relied heavily on requirements for space heating energy in the residential/commercial sector and for process energy and feedstock in the industrial sector. This paper reviews historical gas utilization trends and considers how these are likely to develop in the future. In addition to the above somewhat negative factors, the bright outlook for gas utilization in both large scale and small scale power and cogeneration facilities is reviewed and the implications of power industry restructuring for natural gas utilization are discussed. Finally, the outlook for overall European natural gas demand and trade is briefly considered. (author)

Toward the integration of European natural gas markets:A time-varying approach

International Nuclear Information System (INIS)

Renou-Maissant, Patricia

2012-01-01

Over the past fifteen years, European gas markets have radically changed. In order to build a single European gas market, a new regulatory framework has been established through three European Gas Directives. The purpose of this article is to investigate the impact of the reforms in the natural gas industry on consumer prices, with a specific focus on gas prices for industrial use. The strength of the relationship between the industrial gas prices of six western European countries is studied by testing the Law of One Price for the period 1991–2009. Estimations were carried out using both cointegration analysis and time-varying parameter models. Results highlight an emerging and on-going process of convergence between the industrial gas prices in western Europe since 2001 for the six EU member states. The strength and the level of convergence differ widely between countries. Strong integration of gas markets in continental Europe, except for the Belgian market, has been established. It appears that the convergence process between continental countries and the UK is not completed. Thus, the integration of European gas markets remains an open issue and the question of how far integration will proceed will still be widely discussed in the coming years. - Highlights: ► We investigate the integration of European natural gas markets. ► We use both cointegration analysis and time-varying parameter models. ► We show the failure of cointegration techniques to take account of evolving processes. ► An emerging and on-going process of convergence between the industrial gas prices is at work. ► Strong integration of gas markets in continental Europe has been established.

Profiling unauthorized natural resource users for better targeting of conservation interventions.

2015-12-01

Unauthorized use of natural resources is a key threat to many protected areas. Approaches to reducing this threat include law enforcement and integrated conservation and development (ICD) projects, but for such ICDs to be targeted effectively, it is important to understand who is illegally using which natural resources and why. The nature of unauthorized behavior makes it difficult to ascertain this information through direct questioning. Bwindi Impenetrable National Park, Uganda, has many ICD projects, including authorizing some local people to use certain nontimber forest resources from the park. However, despite over 25 years of ICD, unauthorized resource use continues. We used household surveys, indirect questioning (unmatched count technique), and focus group discussions to generate profiles of authorized and unauthorized resource users and to explore motivations for unauthorized activity. Overall, unauthorized resource use was most common among people from poor households who lived closest to the park boundary and farthest from roads and trading centers. Other motivations for unauthorized resource use included crop raiding by wild animals, inequity of revenue sharing, and lack of employment, factors that created resentment among the poorest communities. In some communities, benefits obtained from ICD were reported to be the greatest deterrents against unauthorized activity, although law enforcement ranked highest overall. Despite the sensitive nature of exploring unauthorized resource use, management-relevant insights into the profiles and motivations of unauthorized resource users can be gained from a combination of survey techniques, as adopted here. To reduce unauthorized activity at Bwindi, we suggest ICD benefit the poorest people living in remote areas and near the park boundary by providing affordable alternative sources of forest products and addressing crop raiding. To prevent resentment from driving further unauthorized activity, ICDs should be

Making the Most of World Natural Heritage—Linking Conservation and Sustainable Regional Development?

Directory of Open Access Journals (Sweden)

Katharina Conradin

2016-03-01

Full Text Available Today, more than 1000 World Heritage (WH sites are inscribed on UNESCO’s list, 228 of which are natural and mixed heritage sites. Once focused primarily on conservation, World Natural Heritage (WNH sites are increasingly seen as promoters of sustainable regional development. Sustainability-oriented regions, it is assumed, are safeguards for conservation and positively influence local conservation goals. Within UNESCO, discussions regarding the integration of sustainable development in official policies have recently gained momentum. In this article, we investigate the extent to which WNH sites trigger sustainability-oriented approaches in surrounding regions, and how such approaches in turn influence the WNH site and its protection. The results of the study are on the one hand based on a global survey with more than 60% of the WNH sites listed in 2011, and on the other hand on a complementary literature research. Furthermore, we analyze the policy framework necessary to support WNH sites in this endeavor. We conclude that a regional approach to WNH management is necessary to ensure that WNH sites support sustainable regional development effectively, but that the core focus of WNH status must remain environmental conservation.

Development of a natural practice to adapt conservation goals to global change.

Science.gov (United States)

Heller, Nicole E; Hobbs, Richard J

2014-06-01

Conservation goals at the start of the 21st century reflect a combination of contrasting ideas. Ideal nature is something that is historically intact but also futuristically flexible. Ideal nature is independent from humans, but also, because of the pervasiveness of human impacts, only able to reach expression through human management. These tensions emerge in current management rationales because scientists and managers are struggling to accommodate old and new scientific and cultural thinking, while also maintaining legal mandates from the past and commitments to preservation of individual species in particular places under the stresses of global change. Common management goals (such as integrity, wilderness, resilience), whether they are forward looking and focused on sustainability and change, or backward looking and focused on the persistence and restoration of historic states, tend to create essentialisms about how ecosystems should be. These essentialisms limit the options of managers to accommodate the dynamic, and often novel, response of ecosystems to global change. Essentialisms emerge because there is a tight conceptual coupling of place and historical species composition as an indicator of naturalness (e.g., normal, healthy, independent from humans). Given that change is increasingly the norm and ecosystems evolve in response, the focus on idealized ecosystem states is increasingly unwise and unattainable. To provide more open-ended goals, we propose greater attention be paid to the characteristics of management intervention. We suggest that the way we interact with other species in management and the extent to which those interactions reflect the interactions among other biotic organisms, and also reflect our conservation virtues (e.g., humility, respect), influences our ability to cultivate naturalness on the landscape. We call this goal a natural practice (NP) and propose it as a framework for prioritizing and formulating how, when, and where to

Research priorities for conservation and natural resource management in Oceania's small-island developing states.

For conservation science to effectively inform management, research must focus on creating the scientific knowledge required to solve conservation problems. We identified research questions that, if answered, would increase the effectiveness of conservation and natural resource management practice and policy in Oceania's small-island developing states. We asked conservation professionals from academia, governmental, and nongovernmental organizations across the region to propose such questions and then identify which were of high priority in an online survey. We compared the high-priority questions with research questions identified globally and for other regions. Of 270 questions proposed by respondents, 38 were considered high priority, including: What are the highest priority areas for conservation in the face of increasing resource demand and climate change? How should marine protected areas be networked to account for connectivity and climate change? What are the most effective fisheries management policies that contribute to sustainable coral reef fisheries? High-priority questions related to the particular challenges of undertaking conservation on small-island developing states and the need for a research agenda that is responsive to the sociocultural context of Oceania. Research priorities for Oceania relative to elsewhere were broadly similar but differed in specific issues relevant to particular conservation contexts. These differences emphasize the importance of involving local practitioners in the identification of research priorities. Priorities were reasonably well aligned among sectoral groups. Only a few questions were widely considered answered, which may indicate a smaller-than-expected knowledge-action gap. We believe these questions can be used to strengthen research collaborations between scientists and practitioners working to further conservation and natural resource management in this region. © 2017 The Authors.

Mitigation and Compensation under EU Nature Conservation Law in the Flemish Region: Beyond the Deadlock for Development Projects?

Directory of Open Access Journals (Sweden)

Hendrik Schoukens

2014-05-01

Full Text Available For years, the predicament of many of the European protected habitats and species in the Flemish Region, as in many other Member States, passed relatively unnoticed. The lack of proper rules and clear implementation rules fuelled the impression amongst project developers and planning authorities that the impacts of project developments on biodiversity did not really warrant closer assessment. However, in the past ten years, strict national case law has significantly altered this view. Faced with tighter judicial scrutiny, the Habitats and Birds Directives were seen as an important obstacle to project development. Hence mitigation and compensation have now come up as novel approaches to better align spatial aspirations with the conservation of nature. In reality, mitigation was often used as a cover-up for projects that would not fit the strict requirements enshrined in the derogatory clauses. Interestingly, the Belgian Council of State showed itself quite cautious in reasserting the lax view of some planning authorities on mitigation and compensation. In reviewing the legality of several new approaches to mitigation and compensation, the Belgian Council of State, which was initially very cautious in quashing decisions that would actually jeopardise major infrastructure developments, has rendered some compelling rulings on the specific application of mitigation and compensatory measures in a spatial planning context. By letting the objectives of EU nature conservation law prevail in the face of economic interests, the recent case law of the Belgian Council of State can be seen as a remarkable example of judicial environmental activism.

Full Text Available Mt. Tara NP was nominated in 2004 within the UNESCO - ROSTE programme, for Man and the Biosphere (MAB Reserve status in Serbia as transboundary 'Peace Park' status between Serbia and Bosnia & Herzegovina. Mt. Tara is one of the most important centres of Balkans and European ecosystems and species diversity. They represent a unique example of well preserved forests in south eastern Europe with numerous endemic and relict species of flora and fauna. In this floristic diversity of Mt Tara of the greatest interest is the Serbian (Pančić's spruce Picea omorika. Mt. Tara NP is characterized by specific geomorphologic, hydrologic, geologic, soil and climatic features. The geographical information system (GIS that we have created has proved an excellent tool for the spatial planning strategy in assessment and conservation of all natural characteristics of Mt. Tara NP, and is helpful to Park management for sustainable use of landscape resources. GIS of Mt. Tara NP includes data on natural, artificial and management themes.

Possible origin of a natural conservation of flavor in an interaction with neutral Higgs bosons

In technicolor models the masses of the neutral pseudo-Goldstone bosons which interact with quarks and leptons without flavor conservation automatically acquire an order of magnitude Mapprox.(m/sub q/#betta#/sub TC/)/sup 1/2/approx.0.2--1 TeV through the Yukawa interaction. As a result, an effective Lagrangian which conserves only light Higgs bosons satisfies the condition of natural flavor conservation

Wind energy is growing worldwide as a source of power generation. Bat assemblages may be negatively affected by wind farms due to the fatality of a significant number of individuals after colliding with the moving turbines or experiencing barotrauma. The implementation of wind farms should follow standard procedures to prevent such negative impacts: avoid, reduce and offset, in what is known as the mitigation hierarchy. According to this approach avoiding impacts is the priority, followed by the minimisation of the identified impacts, and finally, when residual negative impacts still remain, those must be offset or at least compensated. This paper presents a review on conservation measures for bats and presents some guidelines within the compensation scenario, focusing on negative impacts that remain after avoidance and minimisation measures. The conservation strategies presented aim at the improvement of the ecological conditions for the bat assemblage as a whole. While developed under the European context, the proposed measures are potentially applicable elsewhere, taking into consideration the specificity of each region in terms of bat assemblages present, landscape features and policy context regarding nature and biodiversity conservation and management. An analysis of potential opportunities and constraints arising from the implementation of offset/compensation programmes and gaps in the current knowledge is also considered. - Highlights: • Wind energy impacts bat populations in ways not yet fully understood. • As the use of windfarms is growing worldwide greater impacts on bat populations are also expected. • Mitigation hierarchy provides a way to reduce impacts from new wind farm facilities. • Compensation measures may be used to reduce the residual effects on bat populations. • Identify bats ecological needs and compensate according to the existing surroundings

Comparing spatially explicit ecological and social values for natural areas to identify effective conservation strategies.

Bryan, Brett Anthony; Raymond, Christopher Mark; Crossman, Neville David; King, Darran

Consideration of the social values people assign to relatively undisturbed native ecosystems is critical for the success of science-based conservation plans. We used an interview process to identify and map social values assigned to 31 ecosystem services provided by natural areas in an agricultural landscape in southern Australia. We then modeled the spatial distribution of 12 components of ecological value commonly used in setting spatial conservation priorities. We used the analytical hierarchy process to weight these components and used multiattribute utility theory to combine them into a single spatial layer of ecological value. Social values assigned to natural areas were negatively correlated with ecological values overall, but were positively correlated with some components of ecological value. In terms of the spatial distribution of values, people valued protected areas, whereas those natural areas underrepresented in the reserve system were of higher ecological value. The habitats of threatened animal species were assigned both high ecological value and high social value. Only small areas were assigned both high ecological value and high social value in the study area, whereas large areas of high ecological value were of low social value, and vice versa. We used the assigned ecological and social values to identify different conservation strategies (e.g., information sharing, community engagement, incentive payments) that may be effective for specific areas. We suggest that consideration of both ecological and social values in selection of conservation strategies can enhance the success of science-based conservation planning. ©2010 Society for Conservation Biology.

Coupled human and natural systems approach to wildlife research and conservation

Directory of Open Access Journals (Sweden)

Neil H. Carter

2014-09-01

Full Text Available Conserving wildlife while simultaneously meeting the resource needs of a growing human population is a major sustainability challenge. As such, using combined social and environmental perspectives to understand how people and wildlife are interlinked, together with the mechanisms that may weaken or strengthen those linkages, is of utmost importance. However, such integrated information is lacking. To help fill this information gap, we describe an integrated coupled human and natural systems (CHANS approach for analyzing the patterns, causes, and consequences of changes in wildlife population and habitat, human population and land use, and their interactions. Using this approach, we synthesize research in two sites, Wolong Nature Reserve in China and Chitwan National Park in Nepal, to explicate key relationships between people and two globally endangered wildlife conservation icons, the giant panda and the Bengal tiger. This synthesis reveals that local resident characteristics such as household socioeconomics and demography, as well as community-level attributes such as resource management organizations, affect wildlife and their habitats in complex and even countervailing ways. Human impacts on wildlife and their habitats are in turn modifying the suite of ecosystem services that they provide to local residents in both sites, including access to forest products and cultural values. These interactions are further complicated by human and natural disturbance (e.g., civil wars, earthquakes, feedbacks (including policies, and telecouplings (socioeconomic and environmental interactions over distances that increasingly link the focal systems with other distant systems. We highlight several important implications of using a CHANS approach for wildlife research and conservation that is useful not only in China and Nepal but in many other places around the world facing similar challenges.

Citizen science can improve conservation science, natural resource management, and environmental protection

Citizen science has advanced science for hundreds of years, contributed to many peer-reviewed articles, and informed land management decisions and policies across the United States. Over the last 10 years, citizen science has grown immensely in the United States and many other countries. Here, we show how citizen science is a powerful tool for tackling many of the challenges faced in the field of conservation biology. We describe the two interwoven paths by which citizen science can improve conservation efforts, natural resource management, and environmental protection. The first path includes building scientific knowledge, while the other path involves informing policy and encouraging public action. We explore how citizen science is currently used and describe the investments needed to create a citizen science program. We find that:Citizen science already contributes substantially to many domains of science, including conservation, natural resource, and environmental science. Citizen science informs natural resource management, environmental protection, and policymaking and fosters public input and engagement.Many types of projects can benefit from citizen science, but one must be careful to match the needs for science and public involvement with the right type of citizen science project and the right method of public participation.Citizen science is a rigorous process of scientific discovery, indistinguishable from conventional science apart from the participation of volunteers. When properly designed, carried out, and evaluated, citizen science can provide sound science, efficiently generate high-quality data, and help solve problems.

A synthesis of European seahorse taxonomy, population structure, and habitat use as a basis for assessment, monitoring and conservation.

Accurate taxonomy, population demography, and habitat descriptors inform species threat assessments and the design of effective conservation measures. Here we combine published studies with new genetic, morphological and habitat data that were collected from seahorse populations located along the European and North African coastlines to help inform management decisions for European seahorses. This study confirms the presence of only two native seahorse species ( Hippocampus guttulatus and H. hippocampus ) across Europe, with sporadic occurrence of non-native seahorse species in European waters. For the two native species, our findings demonstrate that highly variable morphological characteristics, such as size and presence or number of cirri, are unreliable for distinguishing species. Both species exhibit sex dimorphism with females being significantly larger. Across its range, H. guttulatus were larger and found at higher densities in cooler waters, and individuals in the Black Sea were significantly smaller than in other populations. H. hippocampus were significantly larger in Senegal. Hippocampus guttulatus tends to have higher density populations than H. hippocampus when they occur sympatrically. Although these species are often associated with seagrass beds, data show both species inhabit a wide variety of shallow habitats and use a mixture of holdfasts. We suggest an international mosaic of protected areas focused on multiple habitat types as the first step to successful assessment, monitoring and conservation management of these Data Deficient species.

Domesticating nature? Surveillance and conservation of migratory shorebirds in the "Atlantic Flyway".

Science.gov (United States)

Whitney, Kristoffer

2014-03-01

Using a recent environmental controversy on the U.S. east coast over the conservation of red knots (Calidris canutus rufa) as a lens, I present a history of North American efforts to understand and conserve migratory shorebirds. Focusing on a few signal pieces of American legislation and their associated bureaucracies, I show the ways in which migratory wildlife have been thoroughly enrolled in efforts to quantify and protect their populations. Interactions between wildlife biologists and endangered species have been described by some scholars as "domestication"-a level of surveillance and intervention into nonhuman nature that constitutes a form of dependence. I pause to reflect on this historical trajectory, pointing out the breaks and continuities with older forms of natural history. Using the oft-mobilized Foucauldian metaphor of the panopticon as a foil, I question the utility and ethics of too-easily declaring "domesticated" wildlife an act of "biopower." Instead, I argue that Jacob von Uexküll's "umwelt" from early ecology and ethology, and more contemporary Science and Technology Studies (STS) analyses emphasizing multiple ontologies, offer more illuminating accounts of endangered species science. Neither science, conservation, nor history are well-served by the conflation of wildlife "surveillance" with the language of Foucauldian discipline. Copyright © 2013 Elsevier Ltd.

2018-05-01

Research on development of a learning model for Natural Science base on conservation area in Bengkulu University has been conducted. The research methods were referred to the standard steps of Research and Development. Stage activities were (a) analysis of needs, (b) observation of the ecological aspects of conservation area as a learning resource, and (c) instructional design based on conservation area for secondary school students. The observation results on the ecological aspects revealed that the diversity of plants and animals, at the conservation area were sufficient as a source for learning. The instructional design was prepared in three phase activities namely Introduction-Exploration-Interpretation (IEI), and then it was compiled in a teaching material Based on Surrounding Natural Environment” (BSNE). The results of a limited scale trial at secondary school students in two districts of Bengkulu province showed that, the students who learned using the IEI model at the conservation area have a good performance and critical thinking. The product from the research is a book named BSNE that can be used for teachers and conservation practitioners in doing the learning activities on environmental conservation which involved public participation.

A roadmap for knowledge exchange and mobilization research in conservation and natural resource management.

Science.gov (United States)

Nguyen, Vivian M; Young, Nathan; Cooke, Steven J

2017-08-01

Scholars across all disciplines have long been interested in how knowledge moves within and beyond their community of peers. Rapid environmental changes and calls for sustainable management practices mean the best knowledge possible is needed to inform decisions, policies, and practices to protect biodiversity and sustainably manage vulnerable natural resources. Although the conservation literature on knowledge exchange (KE) and knowledge mobilization (KM) has grown in recent years, much of it is based on context-specific case studies. This presents a challenge for learning cumulative lessons from KE and KM research and thus effectively using knowledge in conservation and natural resources management. Although continued research on the gap between knowledge and action is valuable, overarching conceptual frameworks are now needed to enable summaries and comparisons across diverse KE-KM research. We propose a knowledge-action framework that provides a conceptual roadmap for future research and practice in KE/KM with the aim of synthesizing lessons learned from contextual case studies and guiding the development and testing of hypotheses in this domain. Our knowledge-action framework has 3 elements that occur at multiple levels and scales: knowledge production (e.g., academia and government), knowledge mediation (e.g., knowledge networks, actors, relational dimension, and contextual dimension), and knowledge-based action (e.g., instrumental, symbolic, and conceptual). The framework integrates concepts from the sociology of science in particular, and serves as a guide to further comprehensive understanding of knowledge exchange and mobilization in conservation and sustainable natural resource management. © 2016 Society for Conservation Biology.

Developments on the European energy market. Part 1. Natural gas supply. Extra import covers growing natural gas demand in Europe

International Nuclear Information System (INIS)

Van Gelder, J.W.

2000-01-01

This first part of a series on developments in the European gas market features the growth in gas supply. 35% of the gas demand must be covered from sources outside Europe. For the future additional imports are required from countries such as the Russian Federation, Algeria and Nigeria. Over the next few years the artificial link between ga and oil prices will disappear, bringing the gas price to a structurally lower level. It will be of crucial importance that gas suppliers will not be able to form cartels to keep prices high. All competing projects will curb price increases on the European market, but will definitely result in more freedom of choice for European natural gas consumers

Ecology and Conservation of Steppes and Semi-Natural Grasslands

Directory of Open Access Journals (Sweden)

Valkó Orsolya

2016-12-01

Full Text Available Palaearctic grasslands encompass a diverse variety of habitats, many of high nature value and vulnerability. The main challenges are climate-change, land-use change, agricultural intensification and abandonment. Many measures are in place to address these challenges, through restoration and appropriate management, though more work is necessary. We present eight studies from China/Germany, Greece, Kazakhstan, Russia and Ukraine. The papers cover a wide range of grassland and steppe habitats and cover vegetation ecology, syntaxonomy and zoology. We also conducted a systematic search on steppe and grassland diversity. The greatest number of studies was from China, followed by Germany and England. We conclude that the amount of research being carried out on Eurasian grasslands is inadequate considering their high levels of biodiversity and vulnerability. We hope to encourage readers to address current major challenges, such as how to manage grasslands for the benefit of diverse taxa, to ensure that conservation initiatives concentrate on sites where there is good potential for success and for the generation of realistic and viable conservation strategies.

Market liberalization in the European Natural Gas Market. The importance of capacity constraints and efficiency differences

2009-06-15

In the European Union, energy markets are increasingly being liberalized. A case in point is the European natural gas industry. The general expectation is that more competition will lead to lower prices and higher volumes, and hence higher welfare. This paper indicates that this might not happen for at least two reasons. First, energy markets, including the market for natural gas, are characterized by imperfect competition and increasing costs to develop new energy sources. As a result, new entrants in the market are less efficient than incumbent firms. Second, energy markets, again including the market for natural gas, are associated with capacity constraints. Prices are determined in residual markets where the least efficient firms are active. This is likely to lead to price increases, rather than decreases.

The role of the incentives in the conservation of the natural forests

International Nuclear Information System (INIS)

Castellanos N, Yuli; Fetecua S; Oscar Javier

2002-01-01

To use forest incentives for the favorable conservation of forest that is in private properties is a difficult process that has encountered obstacles since the creation itself of the incentives and their conception through their application on part of farmers. In the actuality, exist tax and economic incentives that principally favor landowners and big companies and that in other cases propitiate deforestation of the natural zones. The certificate of forest incentive for conservation (CIF) is the incentive that is nearest to biodiversity protection but in Colombia hasn't been applied. The economic valuation of the benefits provided by the forest (positives externalities), may solve this conflict, if it compensates proprietors as well as the tropical countries. But the absence of volunteer, to pay people and the countries benefits is a link of a chain that it is missing, since this panorama, the small proprietors of natural zones should organize and work to get tax and economic exemptions. This process should accompany research, technical assistance and financing on part of the national government

A Global Mitigation Hierarchy for Nature Conservation

Abstract Efforts to conserve biodiversity comprise a patchwork of international goals, national-level plans, and local interventions that, overall, are failing. We discuss the potential utility of applying the mitigation hierarchy, widely used during economic development activities, to all negative human impacts on biodiversity. Evaluating all biodiversity losses and gains through the mitigation hierarchy could help prioritize consideration of conservation goals and drive the empirical evaluation of conservation investments through the explicit consideration of counterfactual trends and ecosystem dynamics across scales. We explore the challenges in using this framework to achieve global conservation goals, including operationalization and monitoring and compliance, and we discuss solutions and research priorities. The mitigation hierarchy's conceptual power and ability to clarify thinking could provide the step change needed to integrate the multiple elements of conservation goals and interventions in order to achieve successful biodiversity outcomes.

In this paper, we develop a mixed complementarity equilibrium model for the European natural gas market. This model has producers as Cournot players with conjectured supply functions relative to their rivals. As such, these producers can withhold production to increase downstream prices for greater profits. The other players are taken to be perfectly competitive and are combined with extensive pipeline, seasonal, and other data reflecting the current state of the market. Four market scenarios are run to analyze the extent of market power by these producers as well as the importance of pipeline and storage capacity. (author)

As such, these producers can withhold production to increase downstream prices for greater profits. The other players are taken to be perfectly competitive and are combined with extensive pipeline, seasonal, and other data reflecting the current state of the market. Four market scenarios are run to analyze the extent of market power by these producers as well as the importance of pipeline and storage capacity

Enlightening Butterfly Conservation Efforts: The Importance of Natural Lighting for Butterfly Behavioral Ecology and Conservation

Science.gov (United States)

2018-01-01

Light is arguably the most important abiotic factor for living organisms. Organisms evolved under specific lighting conditions and their behavior, physiology, and ecology are inexorably linked to light. Understanding light effects on biology could not be more important as present anthropogenic effects are greatly changing the light environments in which animals exist. The two biggest anthropogenic contributors changing light environments are: (1) anthropogenic lighting at night (i.e., light pollution); and (2) deforestation and the built environment. I highlight light importance for butterfly behavior, physiology, and ecology and stress the importance of including light as a conservation factor for conserving butterfly biodiversity. This review focuses on four parts: (1) Introducing the nature and extent of light. (2) Visual and non-visual light reception in butterflies. (3) Implications of unnatural lighting for butterflies across several different behavioral and ecological contexts. (4). Future directions for quantifying the threat of unnatural lighting on butterflies and simple approaches to mitigate unnatural light impacts on butterflies. I urge future research to include light as a factor and end with the hopeful thought that controlling many unnatural light conditions is simply done by flipping a switch. PMID:29439549

Russian natural gas policy and its possible effects on European gas markets

International Nuclear Information System (INIS)

Quast, O.; Locatelli, C.

1997-01-01

There is a growing perception among Western European gas experts that Russia has developed a considerable gas surplus - the Russian gas bubble. Thus, the question clearly arises how much gas is available for export and how much gas, over the next 15 to 20 years, can the Russian quasi-monopolist Gazprom market in Western Europe. We consider that Gazprom's export strategy mirrors the approach of Russia's natural gas policy towards the Western European market. In this paper, we will focus on the characteristics of Gazprom's export strategy, its underlying logic, and its impact on Western European gas markets. As a consequence of Gazprom's export strategy, the Russian gas company faces today a price quantity dilemma. Gazprom's problem is to place as much gas as possible in the growing Western European gas market, without destroying downstream gas prices. We argue that Gazprom has adopted a market share expansion and downstream vertical integration strategy, aimed at capturing a part of the downstream gas rent. Although this strategy appears to have initiated a form of gas to gas competition in a number of European consumer markets, this strategy is not based on an aggressive price policy. However, in order to live up to its ambitions, there is a chance that Gazprom will have to somewhat relax traditional contract clauses, such as contract length, indexation terms and take or pay conditions.

Consuming the forest in an environment of crisis: nature tourism, forest conservation and neoliberal agriculture in south India.

Science.gov (United States)

Münster, Daniel; Münster, Ursula

2012-01-01

This article engages ethnographically with the neoliberalization of nature in the spheres of tourism, conservation and agriculture. Drawing on a case study of Wayanad district, Kerala, the article explores a number of themes. First, it shows how a boom in domestic nature tourism is currently transforming Wayanad into a landscape for tourist consumption. Second, it examines how tourism in Wayanad articulates with projects of neoliberalizing forest and wildlife conservation and with their contestations by subaltern groups. Third, it argues that the contemporary commodification of nature in tourism and conservation is intimately related to earlier processes of commodifying nature in agrarian capitalism. Since independence, forest land has been violently appropriated for intensive cash-cropping. Capitalist agrarian change has transformed land into a (fictitious) commodity and produced a fragile and contested frontier of agriculture and wildlife. When agrarian capitalism reached its ecological limits and entered a crisis of accumulation, farming became increasingly speculative, exploring new modes of accumulation in out-of-state ginger cultivation. In this scenario nature and wildlife tourism emerges as a new prospect for accumulation in a post-agrarian economy. The neoliberalization of nature in Wayanad, the authors argue, is a process driven less by new modes of regulation than by the agrarian crisis and new modes of speculative farming.

Nature protection in Greece: an appraisal of the factors shaping integrative conservation and policy effectiveness

International Nuclear Information System (INIS)

Papageorgiou, Kostas; Vogiatzakis, Ioannis N.

2006-01-01

The proliferation of designated areas following the implementation of Natura 2000 in Greece has initiated changes in the protected area design and conservation policy making aiming at delivering action for biodiversity and integrative planning on a wider landscape. Following the sustainability concept, an integrative approach cannot realistically take place simply by extending the protected area and designations. The paper addresses public involvement and inter-sectoral coordination as major procedural elements of integrative management and evaluates the nature and strength of their negative or positive influences on the fulfillment of an integrative vision of nature conservation. A review of the history of protected areas and administration developments in Greece provide useful input in the research. The analysis has shown that the selected network of Natura 2000 sites has been superimposed upon the existing system and resulted in duplication of administrative effort and related legislation. As a result the overall picture of protected areas in the country appears complex, confusing and fragmented. Major failures to integrated conservation perspective can be traced to structural causes rooted in politico-economic power structures of mainstream policy and in a rather limited political commitment to conservation. It is concluded that greater realisation of integrated conservation in Greece necessitates policy reforms related mainly to sectoral legal frameworks to promote environmentalism as well as an increased effort by the managing authorities to facilitate a broader framework of public dialogue and give local communities incentives to sustainably benefit from protected areas

To Conserve or not to Conserve: A case study of Forest Valuation of Tinderet Natural Forest

International Nuclear Information System (INIS)

Lang'at, D.; Cheboieo, J.; Siko, R

2007-01-01

Tinderet natural forest is part of the extensive Mau complex and forms an important hydrological system for lake Victoria. Information on on economic values of most forests in Kenya are not available or scanty. This paper aims at estimating the total economic value of Tinderet forest. Surveys were conducted on 109 households sampled from three villages within five kilometers of the forest. Further information/data was to determine direct use values. Other indirect use values (carbon sequestration and soil conservation) were were estimated by use of secondary data where the data not available, benefit transfer method was adopted. It was established that, the annual direct use of value to forest adjacent households is about Ksh. 33 million. The indirect use value is estimated at Ksh. 270 million and this value accrues to global community and not restricted to Kenya. The opportunity cost of conserving the Tinderet natural forest is estimated at Ksh. 210 million and only about Ksh. 33 million per year accrue as direct use values to the whole community. The current benefit from forest is inadequate to offset the community cost of of leaving the forest in it's present state. Based on this analysis, the government and the local communities are subsidizing the retention of the forest and this subsidy is currently estimated at at Ksh. 67 million through lost opportunity in settlement and income. In order to promote positive attitudes of the community adjustment to the forest on sustainable use of the forest, consumptive use of the forest should be encouraged

1992-01-01

The search for new ecological solutions for public transport has given an important role to natural gas for vehicles in the national context. Under current prices of fuel and costs of plants, the management of a bus fleet running on natural gas allows consistent savings, besides reducing the atmospheric pollution of urban centres. Within this context, solutions offered by current technology available on the market are examined. Low polluting emissions are taken into consideration and a complete analysis of costs and savings is reported. Reference is made to the Thermie European programme which calls for fuel diversification, energy conservation and air pollution abatement

Serampas is an indigenous group that still inhabits forested areas around the Kerinci Seblat National Park (KSNP in the island of Sumatra, Indonesia. The group has occupied the area since several centuries ago, long before the KSNP was officially proclaimed as a national park. The blending of local natural conditions, socio-cultural setting and cosmology has gradually produced a number of local wisdoms and practices to manage the local natural resources. The Serampas traditional resource management practices were not only friendly to the environment, but also encourage the more equitable distribution of natural resources among the members of the Serampas community. Jambak jambu kalko is literally means a list of locally important perennial fruit tree species protected by the Serampas customary system. Beyond the jambak jambu kalko the Serampas also recognize customs, traditions, and values that have important role in managing the local natural resources.

United States natural gas markets, contracts and risks: What lessons for the European Union and Asia-Pacific natural gas markets?

International Nuclear Information System (INIS)

Talus, Kim

2014-01-01

The article examines the natural gas markets of the United States, the European Union and the Asia-Pacific region and their regulation and contractual structures. The article's main focus is on the United States natural gas markets. The European Union and Asia-Pacific markets are compared to this more developed market. By comparing the physical and ideological characteristics of, and differences between, the three main international gas markets, the article exposes the limits of regulatory and contractual transplants in this area of law and policy. Each of these markets is unique, which limits the opportunities for modelling certain market institutions on the basis of the more developed markets in the United States. This applies for both the EU and the Asia-Pacific region. - Highlights: • Differences in the physical markets impact regulation. • Regulatory transplants have risks. • The approach in energy policy should be based on “Law-in-Context” approach

The conservation status and trends of raptors and owls in Europe.

Science.gov (United States)

Burfield, Ian J

2008-09-01

To conserve biodiversity efficiently, an international framework is needed to ensure that national priorities take into account regional and global priorities. BirdLife International has published five comprehensive assessments of the global status of the world's birds and two evaluations of the status of Europe's birds at a continental level. This paper analyzes the results of these assessments in relation to Europe's 56 species of raptors and owls, 18% of which are of global conservation concern, and 64% of which have an unfavorable conservation status in Europe. The European Union (EU) holds half of the total estimated European breeding population of raptors and owls, and European Russia supports another third, but every European country has a responsibility for at least two species of European conservation concern. During the 1990s, more raptors increased than decreased in most EU member states, but the opposite was true in eastern Europe, where many of the most threatened species are concentrated. Given the popularity of these species with the public, and the political commitment to halt the loss of biodiversity by 2010, much more action is needed to monitor and conserve birds of prey.

International and European law on protected areas and climate change: need for adaptation or implementation?

Science.gov (United States)

Cliquet, A

2014-10-01

The protection and management of protected areas must be adapted to the effects of climate change. An important question is if the law on protected areas is capable of dealing with the required changes. In general, both international nature conventions and European Union nature conservation law do not contain any specific provisions on climate change and protected areas. Attention has been paid to this link in non-binding decisions and policy documents. In order to adapt the law to increased dynamics from climate change, more flexibility is needed. This flexibility should not be understood as "legal" flexibility, in the sense of the weakening nature conservation provisions. Scientific uncertainties on the effects of climate change might conflict with the need for legal certainties. In order to adapt to the effects of climate change, the two crucial elements are the strengthening of core protected areas and connectivity between the core areas. At the international level, both elements can be found in non-binding documents. International law enables the required adaptation; however, it often lacks concrete obligations. A stronger legal framework can be found at the level of the European Union. The Birds and Habitats Directives contain sufficient tools to deal with the effects of climate change. The Directives have been insufficiently implemented so far. Especially the central goals of reaching a favorable conservation status and connectivity measures need to be addressed much more in the future.

Urban conservation education programs aim to increase knowledge and awareness towards biodiversity and to change attitudes and behaviour towards the environment. However, to date, few urban conservation education studies have evaluated to what extent these programs have managed to achieve their goals. In this study, we experimentally explored the influence of an urban conservation activity day on individual knowledge, awareness and actions towards biodiversity, in both the short and longer term.We organised three activity days in Paris (France), during which people were invited to participate in urban conservation efforts. Both quantitative (questionnaire) and qualitative (interviews) methods were employed to investigate the influence of this short urban nature experience on the relationships that city-dwellers develop with nearby biodiversity. We found a strong positive correlation between the levels of participation and an immediate interest towards local urban biodiversity. In the longer term, however, although participants claimed to have gained more knowledge, local awareness and interest for species in their daily environment, they did not seem to extend this interest to participating in other related activities. These results highlight the complexity of validating the effectiveness of this type of education program for achieving conservation goals. Although such a short activity may only have a limited environmental impact, it nevertheless seems to increase people's knowledge, awareness, interest and concern. We therefore believe that when repeated locally, these short conservation education programs could enhance people's experience with nature in cities and achieve conservation goals more fully.

The European Union Solidarity Fund: An Important Tool in the Recovery After Large-Scale Natural Disasters

2016-03-01

Full Text Available This paper analyses the situation of the European Union Solidarity Fund, as an important tool in the recovery after large-scale natural disasters. In the last millennium, the European Union countries have faced climate change, which lead to events with disastrous consequences. There are several ex-post financial ways to respond to the challenges posed by large-scale natural disasters, among which EU Solidarity Fund, government funds, budget reallocation, donor assistance, domestic and/or external credit. The EU Solidarity Fund was created in 2002 after the massive floods from the Central Europe as the expression of the solidarity of EU countries. Romania has received financial assistance from the EU Solidarity Fund after the occurrence of major natural disasters, regional and neighbouring country disasters. The assessment of large-scale natural disasters in EU is very important and in order to analyse if there is a concentration of large-scale natural disasters in EU we used the Gini coefficient. In the paper, the method of the statistical analysis and the correlation between several indicators were used to study the financial impacts of large-scale natural disasters in Europe, and especially in Romania.

The natural gas industry in the Czech Republic is one of the oldest in Europe. In the past, natural gas has played a modest role in the Czech energy supply: coal and town gas from coal and lignite were the major energy sources. However, more and more use is made of natural gas, imported from Russia (Gazprom) and Norway. Besides, the Czech natural gas distribution, transportation and storage system occupies a key position in the Central-European natural gas network

Potential Implications of Climate Change on Aegilops Species Distribution: Sympatry of These Crop Wild Relatives with the Major European Crop Triticum aestivum and Conservation Issues.

Ostrowski, Marie-France; Prosperi, Jean-Marie; David, Jacques

2016-01-01

Gene flow from crop to wild relatives is a common phenomenon which can lead to reduced adaptation of the wild relatives to natural ecosystems and/or increased adaptation to agrosystems (weediness). With global warming, wild relative distributions will likely change, thus modifying the width and/or location of co-occurrence zones where crop-wild hybridization events could occur (sympatry). This study investigates current and 2050 projected changes in sympatry levels between cultivated wheat and six of the most common Aegilops species in Europe. Projections were generated using MaxEnt on presence-only data, bioclimatic variables, and considering two migration hypotheses and two 2050 climate scenarios (RCP4.5 and RCP8.5). Overall, a general decline in suitable climatic conditions for Aegilops species outside the European zone and a parallel increase in Europe were predicted. If no migration could occur, the decline was predicted to be more acute outside than within the European zone. The potential sympatry level in Europe by 2050 was predicted to increase at a higher rate than species richness, and most expansions were predicted to occur in three countries, which are currently among the top four wheat producers in Europe: Russia, France and Ukraine. The results are also discussed with regard to conservation issues of these crop wild relatives.

Positives and pathologies of natural resource management on private land-conservation areas.

Science.gov (United States)

Clements, Hayley S; Cumming, Graeme S

2017-06-01

In managed natural resource systems, such as fisheries and rangelands, there is a recognized trade-off between managing for short-term benefits and managing for longer term resilience. Management actions that stabilize ecological attributes or processes can improve productivity in the supply of ecosystem goods and services in the short term but erode system resilience at longer time scales. For example, fire suppression in rangelands can increase grass biomass initially but ultimately result in an undesirable, shrub-dominated system. Analyses of this phenomenon have focused largely on how management actions influence slow-changing biophysical system attributes (such as vegetation composition). Data on the frequency of management actions that reduce natural ecological variation on 66 private land-conservation areas (PLCAs) in South Africa were used to investigate how management actions are influenced by manager decision-making approaches, a largely ignored part of the problem. The pathology of natural resource management was evident on some PLCAs: increased focus on revenue-generation in decision making resulted in an increased frequency of actions to stabilize short-term variation in large mammal populations, which led to increased revenues from ecotourism or hunting. On many PLCAs, these management actions corresponded with a reduced focus on ecological monitoring and an increase in overstocking of game (i.e., ungulate species) and stocking of extralimitals (i.e., game species outside their historical range). Positives in natural resource management also existed. Some managers monitored slower changing ecological attributes, which resulted in less-intensive management, fewer extralimital species, and lower stocking rates. Our unique, empirical investigation of monitoring-management relationships illustrates that management decisions informed by revenue monitoring versus ecological monitoring can have opposing consequences for natural resource productivity and

Full Text Available This study on the natural and degraded natural vegetation of natural areas in the Potchefstroom Municipal Area, forms part of a research programme on spontaneous vegetation in urban open spaces in the North West Province, South Africa. Using a numerical classification technique (TWINSPAN as a first approximation, the classification was refined by applying Braun-Blanquet procedures. The result is a phytosociological table from which 6 plant communities were recognised, which are subdivided in sub-communities and variants, resulting in 18 vegetation units. Some of these vegetation units are similar to communities described previously in natural areas. The presence of degraded natural communities suggests huge anthropogenic influences in certain areas. An ordination (DECORANA scatter diagram shows the distribution of the plant communities along gradients which could be related to vegetation structure, altitude, soil depth, rockiness of soil surface, wetness or dryness of the habitat and number of introduced species. This study contributes to the compilation of a guideline for a conservation orientated management plan for the area, but also created a wealth of new knowledge of the reaction of indigenous plant species under disturbed conditions.

Simulating security of supply effects of the Nabucco and South Stream projects for the European natural gas market

Energy Technology Data Exchange (ETDEWEB)

Dieckhoener, Caroline

2010-12-15

Due to the increasing European import dependency, significant additional natural gas volumes will be required. In addition to the Nord Stream pipeline, the Nabucco and South Stream pipeline are projects planned for the next decade to provide further gas supplies to the European market. As one of the European Union's energy policies' foci is security of supply, the question can be raised if and how these projects contribute to this objective not only in terms of diversification but also in case of supply disruptions such as occurred in 2009 during the Russia-Ukraine gas crisis. This paper discusses the impact of these two major gas import pipeline projects on the South-Eastern Europe gas supply and analyzes their effects on gas flows and marginal cost prices in general and in case of gas supply disruptions via Ukraine in a model-based analysis with the European natural gas infrastructure and dispatch model TIGER.

The boom of massive parallel sequencing (MPS) technology and its applications in conservation of natural and managed populations brings new opportunities and challenges to meet the scientific questions that can be addressed. Genomic conservation offers a wide range of approaches and analytical techniques, with their respective strengths and weaknesses that rely on several implicit assumptions. However, finding the most suitable approaches and analysis regarding our scientific question are often difficult and time-consuming. To address this gap, a recent workshop entitled 'ConGen 2015' was held at Montana University in order to bring together the knowledge accumulated in this field and to provide training in conceptual and practical aspects of data analysis applied to the field of conservation and evolutionary genomics. Here, we summarize the expertise yield by each instructor that has led us to consider the importance of keeping in mind the scientific question from sampling to management practices along with the selection of appropriate genomics tools and bioinformatics challenges. © 2016 John Wiley & Sons Ltd.

Supply prospects and network integration in the European natural gas sector

International Nuclear Information System (INIS)

Bergmann, B.

1998-01-01

At least for the next 10-15 years, natural gas will be the fastest growing energy form in Europe, with a higher rate of growth in consumption (from a lower base) in central Europe than in western Europe. Although most of the prospective demand until 2010 is covered by signed import contracts and indigenous production, important additional gas supply capacity still has to be developed out of a plenitude of reserves within and (in the long run primarily) outside western and central Europe. The real problem is how to mobilise the reserves economically and direct them towards the European market, in competition with other markets. Europe has a sophisticated transmission system whose development has gone hand-in-hand with long-term import agreements. Among the missing links is the Interconnector, which, at the end of 1998, is due to integrate the UK and Ireland into mainland Europe. This is expected to enhance security of supply in both areas, to balance prices and maybe also to foster ideas of liberalisation. Overall, the European gas industry is in an excellent position to develop the supply of gas in an environmentally benign way. The future belongs all the more to natural gas, the fewer the mistakes that are made when it comes to matters of legal frameworks and taxation

The authors set up a database of activity concentration measurements of natural radionuclides (²²⁶Ra, ²³²Th and ⁴⁰K) in building material. It contains about 10,000 samples of both bulk material (bricks, concrete, cement, natural- and phosphogypsum, sedimentary and igneous bulk stones) and superficial material (igneous and metamorphic stones) used in the construction industry in most European Union Member States. The database allowed the authors to calculate the activity concentration index I--suggested by a European technical guidance document and recently used as a basis for elaborating the draft Euratom Basic Safety Standards Directive--for bricks, concrete and phosphogypsum used in the European Union. Moreover, the percentage could be assessed of materials possibly subject to restrictions, if either of the two dose criteria proposed by the technical guidance were to be adopted.

[Hans Jonas: Nature Conservation, Conservation of Life].

Science.gov (United States)

Burgui Burgui, Mario

2015-01-01

This article discusses three of the problems that the German philosopher Hans Jonas studied. The first one addresses the need for a specific ethic dedicated to the moral dimension of environmental problems, from a different perspective to the traditional. The second problem is crucial in the discussion on environmental ethics: the value of the nature. Does the nature have an intrinsic value or an instrumental value only (to satisfy the interests of the human being)? The thesis of Jonas, which claimed that nature is a good in itself, were further elaborated here. And the third problem is the derivation of moral norms and the role of man in this ethic that recognizes a good in itself in nature. According to Jonas, the human being is not diminished by recognizing the intrinsic value of nature, since the man's uniqueness and value are unquestionable. From these three central issues, the paper highlights the importance of seeking the links between bioethics and environmental ethics to address the current environmental, social and economic crisis.

Does conservation on farmland contribute to halting the biodiversity decline?

Kleijn, David; Rundlöf, Maj; Scheper, Jeroen; Smith, Henrik G; Tscharntke, Teja

2011-09-01

Biodiversity continues to decline, despite the implementation of international conservation conventions and measures. To counteract biodiversity loss, it is pivotal to know how conservation actions affect biodiversity trends. Focussing on European farmland species, we review what is known about the impact of conservation initiatives on biodiversity. We argue that the effects of conservation are a function of conservation-induced ecological contrast, agricultural land-use intensity and landscape context. We find that, to date, only a few studies have linked local conservation effects to national biodiversity trends. It is therefore unknown how the extensive European agri-environmental budget for conservation on farmland contributes to the policy objectives to halt biodiversity decline. Based on this review, we identify new research directions addressing this important knowledge gap. Copyright © 2011 Elsevier Ltd. All rights reserved.

Natural gas and deregulation in the European Market

International Nuclear Information System (INIS)

Anon.

2000-01-01

The gas market is progressively moving towards new organizations under the effect of deregulation initiated in the United States, the United Kingdom and transposed to other countries, particularly in Europe, at least for the member countries of the European Union. Within the framework provided by this overall trend, Cedigaz proposes a study titled 'Natural Gas and Deregulation' in order to describe the main developments affecting these markets on account of deregulation. This report is structured on the basis of three main topics (market organization, marketing modes, pricing) which appears to be the most cogent in terms of deregulation. This grouping by major topics accordingly offers a relatively synthetic view of the main trends which could be observed in the European market, for example. The analysis is largely based on the example of the American market and, to a lesser extent, on the British situation. Incidentally, it has adapted the terms 'regulated market' to define conventional markets and 'deregulated market' to define markets which have incorporated the principle of Third Party Access (TPA). This is obviously a mere convention, since in both cases, the gas market, a network market, is regulated either by the State or by an independent agency. Also noteworthy is the diversity of the regulation methods for the network markets. While an underlying principle prevails throughout, particularly the introduction of TPA, political and energy considerations alike are liable to condition strongly the final structure of a given market. The apparently comparable British and American experience thus display substantial differences. In other words, one should not imagine a sudden transposition of either case to the European market. The different States preserve considerable leeway to guide market developments in one direction or another. On the whole, deregulation is not a frozen process, but has to adapt permanently to developments in a market stage-managed by

The increasing fragmentation of forest habitats and the omnipresence of cultivars potentially threaten the genetic integrity of the European wild apple (Malus sylvestris (L.) Mill). However, the conservation status of this species remains unclear in Europe, other than in Belgium and the Czech Republic, where it has been declared an endangered species. The population density of M. sylvestris is higher in the forests of the upper Rhine Valley (France) than in most European forests, with an unbalanced age-structure, an overrepresentation of adults and a tendency to clump. We characterize here the ecology, age-structure and genetic diversity of wild apple populations in the Rhine Valley. We use these data to highlight links to the history of this species and to propose guidelines for future conservation strategies. In total, 255 individual wild apple trees from six forest stands (five floodplain forests and one forest growing in drier conditions) were analysed in the field, collected and genotyped on the basis of data for 15 microsatellite markers. Genetic analyses showed no escaped cultivars and few hybrids with the cultivated apple. Excluding the hybrids, the genetically "pure" populations displayed high levels of genetic diversity and a weak population structure. Age-structure and ecology studies of wild apple populations identified four categories that were not randomly distributed across the forests, reflecting the history of the Rhine forest over the last century. The Rhine wild apple populations, with their ecological strategies, high genetic diversity, and weak traces of crop-to-wild gene flow associated with the history of these floodplain forests, constitute candidate populations for inclusion in future conservation programmes for European wild apple.

With the on-going biodiversity crisis, growing urban lifestyles decrease opportunities to experience nature. However, an intimate relationship with nature has various benefits, for individual well-being, health or attention restoration, but also for environmental issues. Much research effort explored the extent to which people feel being part of the natural world, and thus focused more recently on the importance of reconnecting people – especially urban dwellers – with nature and conservation...

Natural Water Retention Measures (NWRM): from Design to Implementation through European Projects; Las Medidas Naturales de Retencion de Agua: del diseno a la implementacion a traves de proyectos europeos

Magdaleno Mas, F.; Dalacamara Andres, G.

2015-07-01

The Centre for Applied Technique Studies (CETA) of CEDEX has been working over the last few years in different European projects related with the design and development of natural water retention measures (NWRM). These are a number of measures, boosted by the Water Unit of the Environment Directorate-General of the European Commission. with close links to green infrastructures, which try to integrate, from a multifunctional approach, different legal and technical requirements aimed at a better adaptation to extreme hydro meteorological events, environmental protection and conservation, and maintenance of ecosystem services. This paper reviews the underpinning foundations of the concept and the mechanisms for designing and implementing NWRM. It also shows the way they can be applied, by presenting different initiatives developed by CETA since 2008 in Navarra (Arga-Aragon rivers system). For fulfilling those works, CETA has collaborated with environmental and hydraulic authorities of Navarra. It has also actively cooperated with research centres, such as the Institute IMDEA Water. specifically in a European project devoted to the diffusion, assessment, and presentation of NWRM within the context of the EU River Basin Districts.

2016-01-01

Full Text Available A research purpose is the analysis of the European natural gas market environment and the modernization opportunities of the delivery system from Russia in connection with the current geo-economic changes. The main methods are the factorial approaches and the content analysis, which allows allocate and structure this sector’s driving forces.Export of the Russian natural gas on the European market still remains the dominating activity, in terms of the total amounts of deliveries, though over the last ten years its specific weight has been considerably reduced. The situation has sharply become aggravated both in connection with the "Ukrainian" crisis, and that of the European Union policy, which is taking the active measures for the gas supply system diversification. As a result of the conducted research it is proved that the Russian gas transportation system in the Arctic regions requires the strategic upgrade which shall go in two main directions.The first direction is the forming of the new pipeline schemes replacing the unreliable transit routes. The second direction is a rather innovative development of exploration and transportation of the liquefied natural gas which amount exceeds thirty percent in world export and in Russian has not yet reached ten percent.Scientific novelty of the received results consists in system approval of the opportunities of adaptation of Russian export deliveries to the market demand changes. The proposals of increase of the liquefied natural gas exploration in the Arctic regions and formation of the basic centers (special zones have also a practical importance.

Increased competition on the supply side of the Western European natural gas market

International Nuclear Information System (INIS)

Golombek, R.; Gjelsvik, E.; Rosendahl, K.N.

1996-01-01

This publication discusses the impact of breaking up national gas sales consortia in Western Europe. A numerical model of the Western European natural gas market is used to show that once the demand side of the market is liberalized, each producing country has an incentive to break up its national gas sales consortium. The situation is not stable, however, since each country has an incentive to increase the number of domestic producers in response to more competitors. Consequently the model suggests that there may be a large number of producers in a completely liberalized natural gas market. 19 refs., 1 fig., 3 tabs

Digital innovation through partnership between nature conservation organisations and academia: a qualitative impact assessment.

Galán-Díaz, Carlos; Edwards, Peter; Nelson, John D; van der Wal, René

2015-11-01

Nature conservation organisations increasingly turn to new digital technologies to help deliver conservation objectives. This has led to collaborative forms of working with academia to spearhead digital innovation. Through in-depth interviews with three UK research-council-funded case studies, we show that by working with academics conservation organisations can receive positive and negative impacts, some of which cut across their operations. Positive impacts include new ways of engaging with audiences, improved data workflows, financial benefits, capacity building and the necessary digital infrastructure to help them influence policy. Negative impacts include the time and resources required to learn new skills and sustain new technologies, managing different organisational objectives and shifts in working practices as a result of the new technologies. Most importantly, collaboration with academics was shown to bring the opportunity of a profound change in perspectives on technologies with benefits to the partner organisations and individuals therein.

Nature Conservation Against All? Aquatic Macrophyte De-Weeding – Cut or Conserve? A Stakeholder Analysis

Directory of Open Access Journals (Sweden)

Vasco Brummer

2017-12-01

Full Text Available De-weeding of streams and lakes occurs in Germany on a widespread level, mostly to ensure water runoff and to provide flood protection. But de-weeding also affects a range of stakeholders, who have their own reasons to support or oppose it. For the list of stakeholders identified, see chapter 4. As part of a project analysing the feasibility of using water plant biomass as a substrate for biogas production, we conducted a multi-method stakeholder analysis to evaluate stakeholders’ opinions about de-weeding. The results show a preference of all stakeholders, except those identifying with nature conservation, for aquatic de-weeding. Our findings also point to a lack of communication between stakeholders, resulting in biased opinions of the stakeholders against other stakeholders and starting points for conflict.

Conservation businesses and conservation planning in a biological diversity hotspot.

The allocation of land to biological diversity conservation competes with other land uses and the needs of society for development, food, and extraction of natural resources. Trade-offs between biological diversity conservation and alternative land uses are unavoidable, given the realities of limited conservation resources and the competing demands of society. We developed a conservation-planning assessment for the South African province of KwaZulu-Natal, which forms the central component of the Maputaland-Pondoland-Albany biological diversity hotspot. Our objective was to enhance biological diversity protection while promoting sustainable development and providing spatial guidance in the resolution of potential policy conflicts over priority areas for conservation at risk of transformation. The conservation-planning assessment combined spatial-distribution models for 646 conservation features, spatial economic-return models for 28 alternative land uses, and spatial maps for 4 threats. Nature-based tourism businesses were competitive with other land uses and could provide revenues of >US$60 million/year to local stakeholders and simultaneously help meeting conservation goals for almost half the conservation features in the planning region. Accounting for opportunity costs substantially decreased conflicts between biological diversity, agricultural use, commercial forestry, and mining. Accounting for economic benefits arising from conservation and reducing potential policy conflicts with alternative plans for development can provide opportunities for successful strategies that combine conservation and sustainable development and facilitate conservation action. © 2013 Society for Conservation Biology.

Biodiversity conservation efforts in Europe have traditionally focused on farmland and open nature areas such as grasslands, heathlands and meadows, while little attention has been devoted to conservation actions in forest. Using detailed information on the geographical distribution of about 900...... terrestrial species in Denmark we apply systematic conservation planning techniques to identify how to protect biodiversity at the lowest cost to society. The results suggest that conservation actions in forest should be given a higher priority. Thus, three to four times the number of forest species...... are protected per million € compared with species living in open land natural areas. Furthermore, a gap analysis finds the current designation of Natura 2000 and other protected areas is skewed toward open land natural areas, and insufficient to meet the conservation targets on forest species....

A transnational network of genetic conservation units for forest trees was recently documented in Europe aiming at the conservation of evolutionary processes and the adaptive potential of natural or man-made tree populations. In this study, we quantified the vulnerability of individual conservation units and the whole network to climate change using climate favourability models and the estimated velocity of climate change. Compared to the overall climate niche of the analysed target species populations at the warm and dry end of the species niche are underrepresented in the network. However, by 2100, target species in 33-65 % of conservation units, mostly located in southern Europe, will be at the limit or outside the species' current climatic niche as demonstrated by favourabilities below required model sensitivities of 95%. The highest average decrease in favourabilities throughout the network can be expected for coniferous trees although they are mainly occurring within units in mountainous landscapes for which we estimated lower velocities of change. Generally, the species-specific estimates of favourabilities showed only low correlations to the velocity of climate change in individual units, indicating that both vulnerability measures should be considered for climate risk analysis. The variation in favourabilities among target species within the same conservation units is expected to increase with climate change and will likely require a prioritization among co-occurring species. The present results suggest that there is a strong need to intensify monitoring efforts and to develop additional conservation measures for populations in the most vulnerable units. Also, our results call for continued transnational actions for genetic conservation of European forest trees, including the establishment of dynamic conservation populations outside the current species distribution ranges within European assisted migration schemes. © 2013 John Wiley & Sons Ltd.

2010-04-01

Full Text Available The EU Habitats Directive requires all member states to report every 6 years on the implementation of the Directive. The report covering the period 2000 – 2006 included for the first time an assessment of the conservation status of the habitats and species listed on annexes I, II, IV & V of the Habitats Directive following an agreed format. Based on national reports submitted from member States the European Topic Centre on Biological Diversity has prepared assessments for each biogeographical region at EU-level. The majority of the habitats of Annex I are not at favourable status although there is much variation both between countries and regions and between habitats. The results will be discussed at European level and at member state level with a case study of the German national report. At the same time a number of methodical problems became apparent both in Germany and at EU-level. Work is already under way to improve the next report for the period 2007 – 2012. The dimension of management needs, threats and pressures and the time scale for improvements of the conservation status are discussed. Habitats linked to agriculture appear to be particularly unfavourable.

A complementarity model for the European natural gas market

Egging, Ruud; Gabriel, Steven A.; Holz, Franziska; Zhuang, Jifang

2008-01-01

In this paper, we present a detailed and comprehensive complementarity model for computing market equilibrium values in the European natural gas system. Market players include producers and their marketing arms which we call 'traders', pipeline and storage operators, marketers, LNG liquefiers, regasifiers, tankers, and three end-use consumption sectors. The economic behavior of producers, traders, pipeline and storage operators, liquefiers and regasifiers is modeled via optimization problems whose Karush-Kuhn-Tucker (KKT) optimality conditions in combination with market-clearing conditions form the complementarity system. The LNG tankers, marketers and consumption sectors are modeled implicitly via appropriate cost functions, aggregate demand curves, and ex post calculations, respectively. The model is run on several case studies that highlight its capabilities, including a simulation of a disruption of Russian supplies via Ukraine

Despite growing recognition that mineral sites restored for nature conservation can enhance local biodiversity, the wider societal benefits provided by this type of restoration relative to alternative options are not well understood. This study addresses this research gap by quantifying differences in ecosystem services provision under two common mineral site after-uses: nature conservation and agriculture. Using a combination of site-specific primary field data, benefits transfer and modelling, we show that for our sites restoration for nature conservation provides a more diverse array of ecosystem services than would be delivered under an agricultural restoration scenario. We also explore the effects of addressing different conservation targets, which we find alter the provision of ecosystem services on a service-specific basis. Highly species-focused intervention areas are associated with increased carbon storage and livestock grazing provision, whereas non-intervention areas are important for carbon sequestration, fishing, recreation and flood risk mitigation. The results of this study highlight the wider societal importance of restored mineral sites and may help conservation managers and planners to develop future restoration strategies that provide benefits for both biodiversity and human well-being.

European Union response to Fukushima. European stress tests and peer review

Jamet, Philippe [Autorite de Surete Nucleaire (ASN), Paris (France)

2012-07-01

Following the severe accidents which started in the Fukushima Dai-ichi NPP on 11 March 2011, the European Council requested that a comprehensive safety and risk assessment, in light of preliminary lessons learned, be performed on all EU nuclear plants. Therefore, stress tests and peer review assessing natural initiating events, the loss of safety systems and severe accident management have been performed in the 15 European Union countries with nuclear power plants as well as Switzerland and Ukraine. The final peer review report of the European Nuclear Safety Regulators Group (ENSREG) highlights four main areas for improvement to be explored across Europe: 1. Development by the Western European Nuclear Regulators' Association (WENRA), with the contribution of the best available EU expertise, of a European guidance on assessment of natural hazards and margins; 2. Importance of Periodic Safety Review to be underlined by ENSREG; 3. Expeditious implementation of the recognised measures to protect containment integrity; 4. Prevention of accidents resulting from natural hazards and limitation of their consequences. The peer review of the European stress tests was completed in April 2012. In their conclusive statement issued 26 April 2012, the national European regulators and the European Commission as European Nuclear Safety Regulators Group (ENSREG) required that follow-up would occur by way of an ENSREG action plan. Country specific action plans will be developed and peer review workshop will be organised to share lessons learned on the implementation of post-Fukushima safety improvements.

Population Genetic Patterns of Threatened European Mudminnow (Umbra krameri Walbaum, 1792 in a Fragmented Landscape: Implications for Conservation Management.

Directory of Open Access Journals (Sweden)

Péter Takács

Full Text Available The European mudminnow (Umbra krameri is a Middle Danubian endemic fish species, which is characterised by isolated populations living mainly in artificial habitats in the centre of its range, in the Carpathian Basin. For their long term preservation, reliable information is needed about the structure of stocks and the level of isolation. The recent distribution pattern, and the population genetic structure within and among regions were investigated to designate the Evolutionary Significant, Conservation and Management Units (ESUs, CUs, MUs and to explore the conservation biological value of the shrinking populations. In total, eight microsatellite loci were studied in 404 specimens originating from eight regions. The results revealed a pronounced population structure, where strictly limited gene flow was detected among regions, as well as various strengths of connections within regions. Following the results of hierarchical structure analyses, two ESUs were supposed in the Carpathian Basin, corresponding to the Danube and Tisza catchments. Our results recommend designating the borders of CUs in an 80-90km range and 16 clusters should be set up as MUs for the 33 investigated populations. How these genetic findings can be used to better allocate conservation resources for the long term maintenance of the metapopulation structure of this threathened endemic fish is discussed.

Despite broad recognition of the value of social sciences and increasingly vocal calls for better engagement with the human element of conservation, the conservation social sciences remain misunderstood and underutilized in practice. The conservation social sciences can provide unique and important contributions to society's understanding of the relationships between humans and nature and to improving conservation practice and outcomes. There are 4 barriers-ideological, institutional, knowledge, and capacity-to meaningful integration of the social sciences into conservation. We provide practical guidance on overcoming these barriers to mainstream the social sciences in conservation science, practice, and policy. Broadly, we recommend fostering knowledge on the scope and contributions of the social sciences to conservation, including social scientists from the inception of interdisciplinary research projects, incorporating social science research and insights during all stages of conservation planning and implementation, building social science capacity at all scales in conservation organizations and agencies, and promoting engagement with the social sciences in and through global conservation policy-influencing organizations. Conservation social scientists, too, need to be willing to engage with natural science knowledge and to communicate insights and recommendations clearly. We urge the conservation community to move beyond superficial engagement with the conservation social sciences. A more inclusive and integrative conservation science-one that includes the natural and social sciences-will enable more ecologically effective and socially just conservation. Better collaboration among social scientists, natural scientists, practitioners, and policy makers will facilitate a renewed and more robust conservation. Mainstreaming the conservation social sciences will facilitate the uptake of the full range of insights and contributions from these fields into

We identify the provisions that define sustainable hunting according to European law and international treaties, together with their guidance documents. We accept the substantial evidence for lead's actual and potential effects on wildlife, habitats and health as persuasive and assess how these effects relate to stated provisions for sustainability and hunting. We evaluate how continued use of lead ammunition negatively affects international efforts to halt loss of biodiversity, sustain wildlife populations and conserve their habitats. We highlight the indiscriminate and avoidable health and welfare impacts for large numbers of exposed wild animals as ethically unsustainable. In societal terms, continued use of lead ammunition undermines public perceptions of hunting. Given the existence of acceptable, non-toxic alternatives for lead ammunition, we conclude that hunting with lead ammunition cannot be justified under established principles of public/international policy and is not sustainable. Changing from lead ammunition to non-toxic alternatives will bring significant nature conservation and human health gains, and from the hunter's perspective will enhance societal acceptance of hunting. Change will create opportunities for improved constructive dialogue between hunting stakeholders and others engaged with enhancing biodiversity and nature conservation objectives.

Conservation reaches new heights.

The conservation program with the management assistance of the Woodlands Mountain Institute in 2 contiguous parks, the Mount Everest National Park in Nepal and the Qomolangma Nature Reserve in China, in 2 countries is described. The focus is on conservation of the complex ecosystem with sustainable development by showing local people how to benefit from the park without environmental damage. Cultural diversity is as important as biological diversity. The area has been designated by UNESCO as a World Heritage Site with the "last pure ecological seed" of the Himalayas. The regional geography and culture are presented. Population growth has impacted natural resources through overgrazing, cultivation of marginal land, and deforestation; future plans to build a dam and road bordering the nature reserve pose other threats. Proposed management plans for the Makalu-Barun Nature Park (established in November 1991) and Conservation Area include a division of the park into nature reserve areas free of human activity, protected areas which permit traditional land use, and special sites and trail for tourists and religious pilgrims. The conservation area will act as a buffer for the park and provide economic opportunities; further subdivisions include land use for biodiversity protection, community forest and pasture, agroforestry, and agriculture and settlement. Efforts will be made to increase the welfare of women and local people; proposed projects include the introduction of higher milk-producing animals for stall feeding. Also proposed is a cultural and natural history museum. 70% of the project's resources will be directed to local community participation in consultation and park maintenance. The project is a model of how conservation and protection of natural resources can coexist with local economic development and participation; an integration of preservation of biological diversity, mountain wisdom, and the value of local people as resources for conservation.

Full Text Available Natura 2000 is a European network of protected natural areas including a significant number of natural habitats and wild species for the interest of comunnity. Natura 2000 ROSCI 0233 "Someşul Rece"  Site is situated in the south-western county of Cluj, on the administrative territory of Măguri-Răcătău and Ierii Valley. It has an area of 8529 ha and is a framed area of the Apuseni Mountains Alpine bioregions. The site preserves the following natural habitats: Rough mountain beech forests Asperulo-Fagetum, beech forests of Luzulo-Fagetum, forests acidophilous Picea Abies mountain region and protect important species and active fish fauna, flora and fauna of the Apuseni Mountains. It is also home for several species (mammals, amphibians, fish and beetles like: lynx, wolf or otter. The conservation measures of Natura 2000 Somesul Rece Site, elaborated in order to protect the habitats and the species are part of the management plan. These measures were developed in close connection with the conservation status of habitats and species, but also taking into account the needs of local communities. These measures include: maintaining habitats in favorable conservation status; maintain the current habitat areas; preventing and combating poaching and overfishing;ensuring peace in areas of rock (for large mammals.

Most cropland in the United States is characterized by large monocultures, whose productivity is maintained through a strong reliance on costly tillage, external fertilizers, and pesticides (Schipanski et al., 2016). Despite this, farmers have developed a regenerative model of farm production that promotes soil health and biodiversity, while producing nutrient-dense farm products profitably. Little work has focused on the relative costs and benefits of novel regenerative farming operations, which necessitates studying in situ , farmer-defined best management practices. Here, we evaluate the relative effects of regenerative and conventional corn production systems on pest management services, soil conservation, and farmer profitability and productivity throughout the Northern Plains of the United States. Regenerative farming systems provided greater ecosystem services and profitability for farmers than an input-intensive model of corn production. Pests were 10-fold more abundant in insecticide-treated corn fields than on insecticide-free regenerative farms, indicating that farmers who proactively design pest-resilient food systems outperform farmers that react to pests chemically. Regenerative fields had 29% lower grain production but 78% higher profits over traditional corn production systems. Profit was positively correlated with the particulate organic matter of the soil, not yield. These results provide the basis for dialogue on ecologically based farming systems that could be used to simultaneously produce food while conserving our natural resource base: two factors that are pitted against one another in simplified food production systems. To attain this requires a systems-level shift on the farm; simply applying individual regenerative practices within the current production model will not likely produce the documented results.

2013-01-01

Full Text Available The European White Elm (Ulmus effusa Willd. is indicated as a rare and endangered species in the growing stock of the Republic of Serbia. In the area of Great War Island, its natural populations were reduced to 56 registered trees, which occur in three spatially isolated subpopulations. On the basis of the research conducted on the level of variability of adaptible morphometric characteristics of leaves from 14 selected test trees of European White Elm, it can be concluded that the degree of interpopulation variability is satisfactory, which is a good basis for the conservation of the available gene pool.

Impact mitigation is a primary mechanism on which countries rely to reduce environmental externalities and balance development with conservation. Mitigation policies are transitioning from traditional project-by-project planning to landscape-level planning. Although this larger-scale approach is expected to provide greater conservation benefits at the lowest cost, empirical justification is still scarce. Using commercial sugarcane expansion in the Brazilian Cerrado as a case study, we apply economic and biophysical steady-state models to quantify the benefits of the Brazilian Forest Code (FC) under landscape- and property-level planning. We find that FC compliance imposes small costs to business but can generate significant long-term benefits to nature: supporting 32 (±37) additional species (largely habitat specialists), storing 593,000 to 2,280,000 additional tons of carbon worth $69 million to $265 million ($ pertains to U.S. dollars), and marginally improving surface water quality. Relative to property-level compliance, we find that landscape-level compliance reduces total business costs by $19 million to $35 million per 6-year sugarcane growing cycle while often supporting more species and storing more carbon. Our results demonstrate that landscape-level mitigation provides cost-effective conservation and can be used to promote sustainable development.

Econometric modelling of conservation

The issue of energy conservation in general, and conservation in the natural gas markets in particular, has recently had a much lower profile than in the past, when energy prices were significantly higher and energy costs composed a much larger proportion of industrial operating costs than today. The recent downward trend in energy prices has diverted attention away from this issue. In the face of expected significant real price increases, increasing pressure from environmental groups, and directives on the part of regulator authorities, conservation is once again becoming a topic of consideration in the energy industry. From the point of view of gas demand forecasting, conservation has received too little attention. The intentions of this paper are to establish the need for forecasting conservation in the natural gas utility sector, and to construct a model of industrial demand which incorporates conservation and is appropriate for use as a forecasting tool

Biology, ecology, use, conservation and cultivation of round-leaved sundew (Drosera rotundifolia L.: a review

Directory of Open Access Journals (Sweden)

2016-09-01

Full Text Available Drosera rotundifolia is a perennial insectivorous herb which occupies open, wet, oligotrophic habitats such as acidic bogs and poor fens, and specifically grows in Sphagnum-dominated communities. Since mediaeval times the species has been collected from natural habitats and used as a remedy for coughs and pulmonary diseases. Due to the substantial decline of Drosera habitat, the plant has been protected in most European countries since the 1980s, which means that wild D. rotundifolia has become unavailable to the pharmaceutical industry. The persistent demand has stimulated research into the cultivation of Drosera in several European countries. These studies have shown that Drosera cultivation is time-consuming and not (yet cost-effective, and there is a need for the development of cultivation methods. This article reviews the morphology, distribution, ecology and reproduction of Drosera rotundifolia; outlines its commercial use and nature conservation requirements; and describes previous research on its propagation and cultivation.

2017-12-01

The impact of water policy on conserving the Ogallala Aquifer in Groundwater Management District 3 (GMD3) in southwestern Kansas is analyzed using a system-level theoretical approach integrating agricultural water and land use patterns, changing climate, economic trends, and population dynamics. In so doing, we (1) model the current hyper-extractive coupled natural-human (CNH) system, (2) forecast outcomes of policy scenarios transitioning the current groundwater-based economic system toward more sustainable paths for the social, economic, and natural components of the integrated system, and (3) develop public policy options for enhanced conservation while minimizing the economic costs for the region's communities. The findings corroborate previous studies showing that conservation often leads initially to an expansion of irrigation activities. However, we also find that the expanded presence of irrigated acreage reduces the impact of an increasingly drier climate on the region's economy and creates greater long-term stability in the farming sector along with increased employment and population in the region. On the negative side, conservation lowers the net present value of farmers' current investments and there is not a policy scenario that achieves a truly sustainable solution as defined by Peter H. Gleick. This study reinforces the salience of interdisciplinary linked CNH models to provide policy prescriptions to untangle and address significant environmental policy issues.

Methods for the determination of European Union-permitted added natural colours in foods: a review.

Science.gov (United States)

Scotter, M J

2011-05-01

Coupled to increasing consumer demand, food manufacturers have moved towards increased usage of approved natural colours. There is a legal requirement for governments to monitor the consumption of all food additives in the European Union to ensure the acceptable daily intakes (ADIs) are not exceeded, especially by young children. Validated analytical methods are needed to fulfil this requirement. The aim of this paper is to review the available literature on methods of extraction for approved natural colours in food and drink. Available analytical methods for the determination of European Union-permitted natural food colour additives in foods and beverages have been assessed for their fitness for purpose in terms of their key extraction and analysis procedures, selectivity and sensitivity, especially with regard to maximum permitted levels, and their applicability for use in surveillance and in an enforcement role. The advantages and disadvantages of available analytical methods for each of nine designated chemical classes (groups) of natural colours in different food and beverage matrices are given. Other important factors such as technical requirements, cost, transferability and applicability are given due consideration. Gaps in the knowledge and levels of validation are identified and recommendations made on further research to develop suitable methods. The nine designated natural colour classes covered are: 1. Curcumin (E100), 2. Riboflavins (E101i-ii), 3. Cochineal (E120), 4. Chlorophylls--including chlorophyllins and copper analogues (E140-141), 5. Caramel Classes I-IV (E150a-d), 6. Carotenoids (E160a-f, E161b, E161g), 7. Beetroot red (E162), 8. Anthocyanins (E163), and 9. Other colours--Vegetable carbon (E153), Calcium carbonate (E170), Titanium dioxide (E171) and Iron oxides and hydroxides (E172).

Assessment of the release program of the European Roe Deer Capreolus capreolus (Cetartiodactyla: Cervidae at Ajloun Nature Reserve, Jordan

Directory of Open Access Journals (Sweden)

2009-06-01

Full Text Available The release program of European Roe Deer Capreolus capreolus was launched in 1989 when the Royal Society for the Conservation of Nature (RSCN received a donation of four individuals (two males and two females from Turkish-Bulgarian border. The aim of the program was to establish a viable population in the former habitat of the species. The program was ongoing for almost 18 years at Ajloun Forest Reserve. On 19 January 2006, 26 individuals (11 males and 15 females were released in the reserve. After collecting information relating to the breeding and release program, a rapid assessment survey was conducted during August and September 2007. Based on visual census, spoor routes, opportunistic observations and interviews method, a distribution map was produced and it was found that the released population had dispersed inside the reserve. Occasionally, they were found to have wandered outside the reserve, where they used surrounding vineyards for feeding and resting; a total of four individuals of two males and two females were counted. The RSCN has succeeded in establishing a free viable population, in its natural habitat, using effective long-term on-site management. It would be recommendable to establish a socio-economic program, and ongoing outreach programs in order to raise the awareness of the importance of protecting endangered species, and secure continuous funding. a further recommendation would be to provide training in deer management for the ecologist and further staff on the reserve and to implement a monitoring program for the released herd in order to insure the success of the reintroduction program.

a Study on the Introduction of Total Natural Resources Management System Using the Environmental Conservation Value Assessment Map

2018-04-01

The environmental impact assessment system and the environmental plan for the preservation of the land environment are carried out with the aim of preventing damage to the environment caused by human activities, improving the quality of life and creating a pleasant environment. However, despite these various systems, the natural resources have been continuously damaged, and the system to cope with them has been advanced, but there has been a limit to fully conserve natural resources from development. The total amount of natural resources is being promoted as a part of the purpose of supplementing the system, but the evaluation method of the total amount of natural resources suitable for domestic situation is not presented yet. Natural resources are diverse and complicated in their categories and elements, and their measurement units are also diverse, making it difficult to synthesize them into one unit. Therefore, in this study, we proposed a method to calculate the total amount by using the evaluation map of the Environmental Conservation Value Assessment Map (ECVAM) which derives the final achievement with 5 grades using 65 evaluation items. However, we consistently applied the weight twice as much as the grade and did not utilize any information other than the map of ECVAM. The results of this study can be applied to the Total Natural Resources Management System through follow-up study such as application of various environmental information and weighting method.

Decisionmakers need updated, scientifically sound and relevant information to implement appropriate policy measures and make innovative commitments to halt biodiversity loss and improve human well-being. Here, we present a recent science-based synthesis on the biodiversity and ecosystem services of Mexico, intended to be a tool for policymakers. We describe the methodological approach used to undertake such an assessment and highlight the major findings. Organized into five volumes and originally written in Spanish (Capital Natural de México), it summarizes the available knowledge on the components, structure, and functioning of the biodiversity of Mexico; the threats and trajectories of anthropogenic impact, together with its conservation status; and the policies, institutions, and instruments available for its sustainable management. We stress the lessons learned that can be useful for similar exercises in other megadiverse developing countries and identify major gaps and strategic actions to conserve the natural capital in light of the challenges of the Anthropocene.

Low-Intensity Agricultural Landscapes in Transylvania Support High Butterfly Diversity: Implications for Conservation

Science.gov (United States)

Loos, Jacqueline; Dorresteijn, Ine; Hanspach, Jan; Fust, Pascal; Rakosy, László; Fischer, Joern

2014-01-01

European farmland biodiversity is declining due to land use changes towards agricultural intensification or abandonment. Some Eastern European farming systems have sustained traditional forms of use, resulting in high levels of biodiversity. However, global markets and international policies now imply rapid and major changes to these systems. To effectively protect farmland biodiversity, understanding landscape features which underpin species diversity is crucial. Focusing on butterflies, we addressed this question for a cultural-historic landscape in Southern Transylvania, Romania. Following a natural experiment, we randomly selected 120 survey sites in farmland, 60 each in grassland and arable land. We surveyed butterfly species richness and abundance by walking transects with four repeats in summer 2012. We analysed species composition using Detrended Correspondence Analysis. We modelled species richness, richness of functional groups, and abundance of selected species in response to topography, woody vegetation cover and heterogeneity at three spatial scales, using generalised linear mixed effects models. Species composition widely overlapped in grassland and arable land. Composition changed along gradients of heterogeneity at local and context scales, and of woody vegetation cover at context and landscape scales. The effect of local heterogeneity on species richness was positive in arable land, but negative in grassland. Plant species richness, and structural and topographic conditions at multiple scales explained species richness, richness of functional groups and species abundances. Our study revealed high conservation value of both grassland and arable land in low-intensity Eastern European farmland. Besides grassland, also heterogeneous arable land provides important habitat for butterflies. While butterfly diversity in arable land benefits from heterogeneity by small-scale structures, grasslands should be protected from fragmentation to provide

The relevance of US experience to the completion of the European internal energy market for natural gas

Energy Technology Data Exchange (ETDEWEB)

Wood-Collins, John [Little (Arthur D.), Inc., London (GB); Lee, William [Shearman and Sterling, Paris (FR)

1990-01-01

The European Commission's 1988 document on the completion of the internal energy market made a number of recommendations which, if adopted, would significantly affect the European natural gas industry. These were principally that: user's access to transmission systems should be facilitated, in order to permit them direct access to suppliers; greater price transparency should be encouraged, to remove competitive distortions; and fiscal harmonisation should be accelerated, in order to ''level the playing field'' between industrial users in different countries. Advocates of ''open access'' or ''common carriage'', i.e. of a system under which owners of gas pipeline and storage facilities would have a legal obligation to provide transportation and related services to third parties for a specific fee, have argued that adoption of a US-style regulatory system could improve the efficiency of European markets by removing anti-competitive practices. The purpose of this article is to review the arguments on both sides and, in particular, to consider whether US experience may be a relevant model for European authorities to adopt. (author).

Wockner, Gary; Boone, Randall; Schoenecker, Kathryn A.; Zeigenfuss, Linda C.

2015-01-01

Great Sand Dunes National Park and Preserve and the neighboring Baca National Wildlife Refuge constitute an extraordinary setting that offers a variety of opportunities for outdoor recreation and natural resource preservation in the San Luis Valley of Colorado. Adjacent to these federal lands, the Nature Conservancy (TNC) manages the historic Medano Ranch. The total land area of these three conservation properties is roughly 121,500 hectares (ha). It is a remote and rugged area in which resource managers must balance the protection of natural resources with recreation and neighboring land uses. The management of wild ungulates in this setting presents challenges, as wild ungulates move freely across public and private landscapes.

Beyond Nature Appropriation: Towards Post-development Conservation in the Maya Forest

Directory of Open Access Journals (Sweden)

Jose E Martinez-Reyes

2014-01-01

Full Text Available The establishment of biosphere reserves in Mexico was followed by alternative livelihood conservation/development projects to integrate indigenous groups into Western style conservation under the idea of sustainable development and participation. In this paper, I discuss the outcomes of two forest wildlife management projects in one Maya community along the Sian Ka′an Biosphere Reserve in the state of Quintana Roo. Both projects ultimately failed and the community mobilised and expelled the NGO from the community. I argue that the failure of these projects involved two dynamics: 1 lack of coherence between the objectives of state agencies, conservation NGOs, and the local community; and 2 unequal ethnic relations, reproducing relations of colonial inequality and dictating how indigenous groups can participate in managing a territory for conservation. If collaboration and local participation are key in conservation management programs, these case studies suggest that greater institutional accountability and community autonomy are needed to make the practice of conservation more democratic and participatory. The expulsion of the NGO as a conservation and development broker also opened the space for, and possibilities of, post-development conservation practice that challenges the normalising expectations of Western biodiversity conservation.

Pricing the (European) option to switch between two energy sources: An application to crude oil and natural gas

International Nuclear Information System (INIS)

Gatfaoui, Hayette

2015-01-01

We consider a firm, which can choose between crude oil and natural gas to run its business. The firm selects the energy source, which minimizes its energy or production costs at a given time horizon. Assuming the energy strategy to be established over a fixed time window, the energy choice decision will be made at a given future date T. In this light, the firm's energy cost can be considered as a long position in a risk-free bond by an amount of the terminal oil price, and a short position in a European put option to switch from oil to gas by an amount of the terminal oil price too. As a result, the option to switch from crude oil to natural gas allows for establishing a hedging strategy with respect to energy costs. Modeling stochastically the underlying asset of the European put, we propose a valuation formula of the option to switch and calibrate the pricing formula to empirical data on a daily basis. Hence, our innovative framework handles widely the hedge against the price increase of any given energy source versus the price of another competing energy source (i.e. minimizing energy costs). Moreover, we provide a price for the cost-reducing effect of the capability to switch from one energy source to another one (i.e. hedging energy price risk). - Highlights: • We consider a firm, which chooses either crude oil or natural gas as an energy source. • The capability to switch offers the firm a hedge against energy commodity price risk. • A European put option prices the ability to switch from crude oil to natural gas. • The capability to switch between two energy sources reduces the firm's energy costs. • The discount illustrates the efficiency of the energy management policy (e.g. timing).

What is a conservation actor?

Directory of Open Access Journals (Sweden)

Paul Jepson

2011-01-01

Full Text Available As a crisis-oriented discipline, conservation biology needs actions to understand the state of nature and thwart declines in biodiversity. Actors-traditionally individuals, institutions, and collectives-have been central to delivering such goals in practice. However, the definition of actors within the discipline has been narrow and their role in influencing conservation outcomes inadequately conceptualised. In this paper, we examine the question ′What is a conservation actor?′ Who or what creates the capacity to influence conservation values and actions? Drawing from theoretical developments in Actor-Network Theory and collective governance, we argue that the concept of an actor in conservation biology should be broadened to include non-humans, such as species and devices, because they have the agency and ability to influence project goals and outcomes. We illustrate this through four examples: the Asian elephant, International Union for Conservation of Nature red lists, the High Conservation Value approach, and an Integrated Conservation and Development Project. We argue that a broader conceptualisation of actors in conservation biology will produce new forms of understanding that could open up new areas of conservation research, enhance practice and draw attention to spheres of conservation activity that might require stronger oversight and governance.

Geopolitics of European natural gas demand: Supplies from Russia, Caspian and the Middle East

Bilgin, Mert

2009-01-01

This paper addresses issues of natural gas which raise questions about European energy security. It first focuses on the rising gas demand of the EU27 and elaborates alleged risks of dependence on Russia such as Gazprom's disagreement with Ukraine, which became an international gas crisis in January 2006 and also more recently in January 2009. Incentives and barriers of Europe's further cooperation with selected Caspian (Azerbaijan, Kazakhstan and Turkmenistan) and Middle Eastern (Iran, Iraq and Egypt) countries are discussed. Supplies from Caspian are analyzed with a particular focus on Russia's role and the vested interests in the region. Supplies from the Middle East are elaborated with regard to Iran's huge and Iraq's emerging potentials in terms of natural gas reserves and foreign direct investments in the energy sector. The geopolitical analysis leads to a conclusion that the best strategy, and what seems more likely, for the EU is to include at least two countries from Azerbaijan, Turkmenistan, Iran and Iraq within its natural gas supply system.

There is scarce information about European folk knowledge of wild invertebrate fauna. We have documented such folk knowledge in three regions, in Romania, Slovakia and Croatia. We provide a list of folk taxa, and discuss folk biological classification and nomenclature, salient features, uses, related proverbs and sayings, and conservation. We collected data among Hungarian-speaking people practising small-scale, traditional agriculture. We studied "all" invertebrate species (species groups) potentially occurring in the vicinity of the settlements. We used photos, held semi-structured interviews, and conducted picture sorting. We documented 208 invertebrate folk taxa. Many species were known which have, to our knowledge, no economic significance. 36 % of the species were known to at least half of the informants. Knowledge reliability was high, although informants were sometimes prone to exaggeration. 93 % of folk taxa had their own individual names, and 90 % of the taxa were embedded in the folk taxonomy. Twenty four species were of direct use to humans (4 medicinal, 5 consumed, 11 as bait, 2 as playthings). Completely new was the discovery that the honey stomachs of black-coloured carpenter bees (Xylocopa violacea, X. valga) were consumed. 30 taxa were associated with a proverb or used for weather forecasting, or predicting harvests. Conscious ideas about conserving invertebrates only occurred with a few taxa, but informants would generally refrain from harming firebugs (Pyrrhocoris apterus), field crickets (Gryllus campestris) and most butterflies. We did not find any mythical creatures among invertebrate folk taxa. Almost every invertebrate species was regarded as basically harmful. Where possible, they were destroyed or at least regarded as worth eradicating. However, we could find no evidence to suggest any invertebrate species had suffered population loss as a result of conscious destruction. Sometimes knowledge pertaining to the taxa could have more

Convergence of European spot market prices for natural gas. A Real-Time Analysis of market integration using the Kalman filter

2005-01-01

This paper provides a textbook example of an econometric analysis of the integration between two commodity markets and the subsequent price convergence or absence thereof. We analyze price relations between spot markets for natural gas in Europe. The European market for natural gas is currently undergoing a liberalization process with the aim of creating a single, unified market. We use time-varying coefficient estimation models, applying the Kalman filter to test whether price convergence between different locations is really taking place. Our results reveal that the construction of a pipeline between the UK and Zeebrugge (Belgium) has lead to almost perfect price convergence between theses locations; on the other hand, liberalization on the European continent does not seem to be working so far.

Travelling energy systems: knowledge transfer for energy efficiency and conservation from European to Australian building projects

Energy Technology Data Exchange (ETDEWEB)

Glad, Wiktoria (Tema Technology and Social Change, Linkoeping Univ. (Sweden); Inst. for Sustainable Futures, Univ. of Technology, Sydney (Australia))

Energy efficiency and conservation in the Australian built environment have not yet been implemented to any great extent. Despite favourable prerequisites, such as vast windswept unpopulated areas suitable for wind power and many hours of direct sunlight in most populated areas, electricity is mainly generated by burning brown coal and buildings are poorly equipped for hot summers and cool winters. Australia urgently needs to convert to alternative energy sources and implement energy efficiency measures, since its carbon dioxide emissions per capita are among the highest in the world. In a recent major redevelopment in Sydney, the Carlton and United Brewery (CUB) site knowledge of energy efficiency and conservation measures used in European buildings was transferred and implemented in local designs and infrastructure. This knowledge came mainly from urban planning and developments in London, but also from high-profile architectural firms based in Paris and Germany. The arrival of this knowledge in Australia led to phases when the knowledge was translated and enacted in local spaces and the constituent ideas were transformed into action. The present research is based on ten months of ethnographic fieldwork in which the planning and design of the CUB site was observed. The results of the study identify barriers to and opportunities for energy system knowledge transfer between different cultures and local spaces. Substantial time must be spent overcoming cultural barriers, so the involved parties can start talking the same language. This is not only true for stakeholders operating in different continents, but for stakeholders operating in different local arenas in the same country.

Vanderhoeven, Sonia; Piqueray, Julien; Halford, Mathieu; Nulens, Greet; Vincke, Jan; Mahy, Grégory

2011-03-01

We conducted a survey to determine how two professional sectors in Belgium, horticulture professionals and nature reserve managers (those directly involved in conservation), view the issues associated with invasive plant species. We developed and utilized a questionnaire that addressed the themes of awareness, concept and use of language, availability of information, impacts and, finally, control and available solutions. Using co-inertia analyses, we tested to what extent the perception of invasive alien species (IAS) was dependent upon the perception of Nature in general. Only forty-two percent of respondent horticulture professionals and eighty-two percent of nature reserve managers had a general knowledge of IAS. Many individuals in both target groups nonetheless had an accurate understanding of the scientific issues. Our results therefore suggest that the manner in which individuals within the two groups view, or perceive, the IAS issue was more the result of lack of information than simply biased perceptions of target groups. Though IAS perceptions by the two groups diverged, they were on par with how they viewed Nature in general. The descriptions of IAS by participants converged with the ideas and concepts frequently found in the scientific literature. Both managers and horticulture professionals expressed a strong willingness to participate in programs designed to prevent the spread of, and damage caused by, IAS. Despite this, the continued commercial availability of many invasive species highlighted the necessity to use both mandatory and voluntary approaches to reduce their re-introduction and spread. The results of this study provide stakeholders and conservation managers with practical information on which communication and management strategies can be based.

The Features of Naturalization of Invasive Fraction of Flora in the Voronezh Region and in Some Regions of the European Part of Russia

Full Text Available The article is about naturalization features of invasive fraction of flora in Voronezh and some other regions of the European part of Russia. The summary table represents all invasive and potentially invasive plants of the European part of Russia with their level of naturalization (or invasive status. Invasive fraction of flora in the Voronezh region numbers 120 plants. All of them are on different stages of naturalization process in an anthropogenic areal. Invasive plants represent by agriophyts – 41 (34,1 % species, epecophyts – 75 (62,5 % species and colonophyts-epecophyts – 4 (3,4 % species. Totally there are 201 species of invasive and potentially invasive plants spread within European part of Russia (Northern-West Russia, Ivanovo, Kaluga, Tver, and Voronezh regions. They formed the “black list” of European Russia. 10 species are common to all invasive fractions. These are Acer negundo, Amelanchier x spicata, Aster x salignus, Echinocystis lobata, Elodea canadensis, Heracleum sosnowskyi, Impatiens glandulifera, Impatiens parviflora, Juncus tenuis and Lupinus polyphyllus. The analysis of the general list of invasive fractions of European Russia shows that 120 species of the list are invasive or potentially invasive in the Voronezh region (100 and 20 species in accordance, adventives naturalized species – 31, native species – 19, archaeophyts – 2, apophyts – 4. 26 species from the list were not found in the Voronezh region. Apparently, the region is a transit area for many invasive plants, which migrate from South to North, from East to West etc. Not only its natural and climatic potential, but also high level of transformation of local landscapes enabled immigrant-plants to naturalize within the bounds of the region. Furthermore, for many years the Voronezh region was the center of introduction of alien plants. Many of those became a part of invasion fraction of regional flora. In recent decades green building took place of

Role of New Nature Reserve in Assisting Endangered Species Conservation - Case Study of Giant Pandas in the Northern Qionglai Mountains, China.

Directory of Open Access Journals (Sweden)

Full Text Available The creation of nature reserves is the most direct way to save endangered species populations and their habitat. Development of the giant panda (Ailuropoda melanoleuca nature reserve network in China was initiated in the 1960s, though the effort to create new reserves boomed considerably after the year 2000. Given this rapid development of protected areas in panda habitats, and the potential conflicting interests between conservation administrations and local economic development, it is essential to assess the role of new nature reserves in the overall giant panda conservation effort and reserve network. We utilized data from national giant panda surveys conducted in 2000 and 2012 to compare the size, spatial use, and distribution of panda populations, as well as the habitat suitability and connectivity in the Northern Qionglai Mountains between the two survey years. Our results show that although the total giant panda population in the study area did not change remarkably, local changes did occur. Most notably, the population in Wolong Nature Reserve declined by 27.3% (N = 39 and the population in Caopo Nature Reserve increased by 71.4% (N = 29 over the 12-year study period. We also found habitat suitability and availability decreased in both Wolong (12.4% and Caopo (7.4%, but that the relative density of giant pandas declined (19.2% and increased (84.6% at each site, respectively. The distance between centers of high IUA were more distant in 2012 (14.1±1.9km than that in 2000 (6.1±0.9km; t = -7.4, df = 5, p = 0.001, showing a scattered spatial pattern. Habitat availability decreased by 42% within the corridor between the two reserves, however panda occurrences in the corridor increased 24.6%. Compared to the total number of encounters, the proportion of the corridor increased 45.76%. Our results show the importance and success of the newly established Caopo to the conservation of giant pandas, and how crucial it is to identify and repair

ROUNDTABLE - SESSION 2 EXPLOITATION, CONSERVATION AND LEGISLATION

Directory of Open Access Journals (Sweden)

EDSMAN L.

2004-01-01

Full Text Available The link between socioeconomics and conservation and the role of legislation in conservation work was discussed in the group with participants from nine European countries. Interest and knowledge among the general public, stakeholders and managers is the key to successful conservation of native crayfish species. Exploitation and conservation do not necessarily exclude each other. A controlled fishery, where it can be sustained, may be an essential tool for conservation by increasing the general awareness and involving more people in the task of protecting the native crayfish species. This strategy is mainly possible for the noble crayfish in the northern part of its distribution, where strong traditions connected to crayfish also exist. A balance between utilisation and overexploitation has to be found and local guidelines for sustainable exploitation produced. Media, the Internet and educational material aimed at schools and stakeholders are excellent ways of reaching a wide audience with information. Universal objectives, rules and regulations at the European level are desirable and the noble crayfish and the stone crayfish should be included in Annex II of the Habitat Directive. Based on this framework detailed regulations are best worked out at the national level, considering the specific crayfish situation in the country. Information about the legislation, the purpose of the legislation and the consequences when not obeying it should be distributed. Stricter regulation of the trade with live alien crayfish is vital because of the associated risk of introducing new diseases and species.

Does the European natural gas market pass the competitive benchmark of the theory of storage? Indirect tests for three major trading points

International Nuclear Information System (INIS)

Stronzik, Marcus; Rammerstorfer, Margarethe; Neumann, Anne

2009-01-01

This paper presents the first comparative analysis of the relationship between natural gas storage utilization and price patterns at three major European trading points. Using two indirect tests developed by that are applied in other commodity markets, we impose the no arbitrage condition to model the efficiency of the natural gas market. The results reveal that while operators of European storage facilities realize seasonal arbitrage profits, substantial arbitrage potentials remain. We suggest that the indirect approach is well suited to provide market insights for periods with limited data. We find that overall market performance differs substantially from the competitive benchmark of the theory of storage. (author)

The effect of gamma radiation was evaluated on the microbiological population, soluble solids content, acidity, p H and ascorbic acid content of natural orange juice. Microbial activity may cause deterioration of orange juice. Irradiation is a process of food conservation which eliminates microorganisms. nevertheless radiation may affect some characteristics of irradiated food. The experimental design was a 4 x 5 factorial scheme, including control and 3 rates of irradiation (2.0, 4.0 and 6.0 kGy) and 5 storage periods (1, 7, 14, 21 and 28 days), with 2 replicates. Samples of juice were extracted from variety Pera oranges and irradiated at a rate of 2.0 kGy/h ( 60 Cobalt) and thereafter stored at 5 +- 3 deg C. Results showed small changes in soluble solids content, acidity and p H, for all treatments. The ratio soluble solids/acidity was also determined and showed little variation for all treatments. There was a reduction on ascorbic acid content of the orange juice with increased radiation dosage and storage time. Gamma radiation was effective in reducing the microbiological population of the juice. (author)

Fate of semi-natural grassland in England between 1960 and 2013: A test of national conservation policy

Directory of Open Access Journals (Sweden)

Lucy E. Ridding

2015-07-01

Full Text Available It is well documented that significant losses in semi-natural grassland occurred across Europe during the second half of the twentieth century. However, comparatively few studies have investigated and quantified the fate of large numbers of individual grassland areas. This is important for understanding the causes of decline, and consequently establishing new policies to conserve and restore lost habitats. This study addresses this problem; GIS was used to compare historic survey data collected between 1960 and 1981 with two contemporary spatial datasets of habitats in England. The datasets included the Priority Habitats Inventory 2013 and the Land Cover Map 2007 and this was undertaken for different types of semi-natural grassland across England. Considerable decreases occurred across the different grassland types, with a loss of 47% of studied semi-natural grasslands sites in England over 32–53 years. Of this, the majority of grassland was lost to conversion to agriculturally-improved grassland or arable cultivation, 45% and 43% respectively. Changes to woodland and urban areas were also evident, but on a much smaller scale. Sites receiving statutory protection as a Site of Special Scientific Interest were found to have retained more grassland (91%, compared with non-protected sites (27%, thus highlighting the effectiveness of this aspect of current conservation policy in England, and the need for this to continue in the future.

A Conservation Ethic and the Collecting of Animals by Institutions of Natural Heritage in the Twenty-First Century: Case Study of the Australian Museum

Directory of Open Access Journals (Sweden)

Timothy Ikin

2011-02-01

Full Text Available Collecting of animals from their habitats for preservation by museums and related bodies is a core operation of such institutions. Conservation of biodiversity in the current era is a priority in the scientific agendas of museums of natural heritage in Australia and the world. Intuitively, to take animals from the wild, while engaged in scientific or other practices that are supposed to promote their ongoing survival, may appear be incompatible. The Australian Museum presents an interesting ground to consider zoological collecting by museums in the twenty-first century. Anderson and Reeves in 1994 argued that a milieu existed that undervalued native species, and that the role of natural history museums, up to as late as the mid-twentieth century, was only to make a record the faunal diversity of Australia, which would inevitably be extinct. Despite the latter, conservation of Australia’s faunal diversity is a key aspect of research programmes in Australia’s institutions of natural heritage in the current era. This paper analyses collecting of animals, a core task for institutions of natural heritage, and how this interacts with a professed “conservation ethic” in a twenty-first century Australian setting.

Corporate realignments in the natural gas industry: does the North American experience foretell the future for the European Union?

This paper seeks to explore the extent to which the corporate realignments which have occurred in the North American Natural Gas Industry during a now relatively lengthy experience with liberalization involving a large number of players, will be imitated in the future by European Union countries other than the UK (which is of course already long-embarked along the path of Anglo-Saxon liberalization). The paper first of all catalogues the North American experience, drawing on company performance data assembled by the authors over the last decade (Rutledge and Wright, 1993, 1995, 1997, 1999, 2000). Secondly, this empirical exploration gives way to theoretical speculation: are there elements of the North American experience for which explanatory generalizations are possible? Thirdly, these empirical and theoretical insights are employed to identify and explore actual and potential differences in the corporate evolution of the European Union natural gas industry.

This paper addresses issues of natural gas which raise questions about European energy security. It first focuses on the rising gas demand of the EU27 and elaborates alleged risks of dependence on Russia such as Gazprom's disagreement with Ukraine, which became an international gas crisis in January 2006 and also more recently in January 2009. Incentives and barriers of Europe's further cooperation with selected Caspian (Azerbaijan, Kazakhstan and Turkmenistan) and Middle Eastern (Iran, Iraq and Egypt) countries are discussed. Supplies from Caspian are analyzed with a particular focus on Russia's role and the vested interests in the region. Supplies from the Middle East are elaborated with regard to Iran's huge and Iraq's emerging potentials in terms of natural gas reserves and foreign direct investments in the energy sector. The geopolitical analysis leads to a conclusion that the best strategy, and what seems more likely, for the EU is to include at least two countries from Azerbaijan, Turkmenistan, Iran and Iraq within its natural gas supply system.

Peat is involved in the global carbon cycle and water conservation; therefore, it is implicated in global environmental change. Microorganisms play an important role in the function of peat. To investigate the bacterial communities in peat of Gahai Lake, different locations and depths were sampled and Illumina Miseq sequencing was used to analyze the microbial community. Chemical properties of peat samples were analyzed by China state standard methods (GB methods). The results showed that bacterial communities were affected by depth, with bacterial diversity and community structure at 90 and 120 cm significantly different from that at 10, 30 and 50 cm depth from the peat surface. Chemical properties of peat land including organic matter, total nitrogen and humus content did not significantly influence bacterial community structure in peat, with only one group from genus Rhizomicrobium that was significantly correlated with total nitrogen. A substantial proportion of the bacterial sequences were unclassified (1.4%), which indicates the great application potential of peat in the Gahai Lake natural conservation area in the future.

Green Belt Europe – nature knows no boundaries. From “Iron Curtain” to Europe’s lifeline

Directory of Open Access Journals (Sweden)

Liana Geidezis

2004-01-01

Full Text Available The “Iron Curtain” divided Europe for almost forty years from the Barents Sea to the Black Sea. It was a political, ideological and physical barrier, most strongly expressed in Germany. Despite its inhumanity, this border granted nature a pause for breath: nature flourished and developed something extremely rare in intensively used landscapes – the so called Green Belt. Since the fall of the Iron Curtain in 1989, a lifeline of habitats about 8.500 km long runs through Europe. It originated from the project Green Belt Germany, initiated by BUND, the vision of a European Green Belt development. It can become a backbone of an ecological network that is a global symbol for trans-boundary co-operation in nature conservation and sustainable development. Moreover, it connects people and shows that the enlarged European Union has not only a cultural but also a natural heritage. The Green Belt is a unique chance to overcome the old boundaries and barriers between East and West – a living symbol of growing together in Europe.

Credibility and advocacy in conservation science

Horton, Cristi C.; Peterson, Tarla Rai; Banerjee, Paulami

2015-01-01

Abstract Conservation policy sits at the nexus of natural science and politics. On the one hand, conservation scientists strive to maintain scientific credibility by emphasizing that their research findings are the result of disinterested observations of reality. On the other hand, conservation scientists are committed to conservation even if they do not advocate a particular policy. The professional conservation literature offers guidance on negotiating the relationship between scientific objectivity and political advocacy without damaging conservation science's credibility. The value of this guidance, however, may be restricted by limited recognition of credibility's multidimensionality and emergent nature: it emerges through perceptions of expertise, goodwill, and trustworthiness. We used content analysis of the literature to determine how credibility is framed in conservation science as it relates to apparent contradictions between science and advocacy. Credibility typically was framed as a static entity lacking dimensionality. Authors identified expertise or trustworthiness as important, but rarely mentioned goodwill. They usually did not identify expertise, goodwill, or trustworthiness as dimensions of credibility or recognize interactions among these 3 dimensions of credibility. This oversimplification may limit the ability of conservation scientists to contribute to biodiversity conservation. Accounting for the emergent quality and multidimensionality of credibility should enable conservation scientists to advance biodiversity conservation more effectively. PMID:26041036

Cotton is an economically important crop and its production is challenged by the diversity of pests and related insecticide resistance. Identification of the conserved target across the cotton pest will help to design broad spectrum insecticide. In this study, we have identified conserved sequences by Expressed Sequence Tag profiling from three cotton pests namely Aphis gossypii, Helicoverpa armigera, and Spodoptera exigua. One target protein arginine kinase having a key role in insect physiology and energy metabolism was studied further using homology modeling, virtual screening, molecular docking, and molecular dynamics simulation to identify potential biopesticide compounds from the Zinc natural database. We have identified four compounds having excellent inhibitor potential against the identified broad spectrum target which are highly specific to invertebrates.

These general paleoecological observations and others that have emerged from case studies of particular problems can improve the preservation of biodiversity and ecosystem functions. Nature conservation requires the full consideration of palaeoecological knowledge in an ecological context, along with the synergistic cooperation of palaeoecologists with neoecologists, anthropologists, and conservation scientists.

Stigma associated with depression is a major public health issue in the EU, with over 20 million people experiencing depression and its associated personal distress each year. While most programmes against stigma related to mental health problems are of a general nature, the knowledge about programmes tackling stigma against people with depression is limited. This study therefore aims to assess the nature and impact of depression-specific programmes in EU countries. Using a web-based tool, 26 programmes were identified across the 18 EU countries taking part in the study. Most were universal and targeted the whole population, while many also targeted specific population groups or settings, such as young people or health professionals. The most common programme aim was improving literacy, although reducing stigmatizing attitudes and discriminatory behaviour and promoting help-seeking were also common. Most programmes originated from professional bodies, or as grassroots initiatives from service user groups/NGOs, rather than as part of national and local policy. The approaches used were primarily different forms of education/information, with some, but very limited, use of positive personal contact. Overall, the quality and extent of impact of the programmes was limited, with few leading to peer-reviewed publications. Specific programmes were identified with evidence of positive impact, and we drew on these examples to develop a framework to be used for future programmes against stigma and discrimination associated with depression.

Increasing species richness of light demanding species in forests may not be a conservation concern if we accept a macroecological and evolutionary baseline for biodiversity. Most of the current biodiversity in Europe has evolved in the Pleistocene or earlier, and in ecosystems markedly influenced by dynamic natural processes, including grazing. Many threatened species are associated with high-light forest environments such as forest glades and edges, as these have strongly declined at least partially due to the decline of large herbivores in European forests. Hence, moderate grazing in forests should be an ecological baseline and conservation target rather than a concern. © 2017 John Wiley & Sons Ltd.

Geography of conservation spending, biodiversity, and culture.

Science.gov (United States)

McClanahan, T R; Rankin, P S

2016-10-01

We used linear and multivariate models to examine the associations between geography, biodiversity, per capita economic output, national spending on conservation, governance, and cultural traits in 55 countries. Cultural traits and social metrics of modernization correlated positively with national spending on conservation. The global distribution of this spending culture was poorly aligned with the distribution of biodiversity. Specifically, biodiversity was greater in the tropics where cultures tended to spend relatively less on conservation and tended to have higher collectivism, formalized and hierarchical leadership, and weaker governance. Consequently, nations lacking social traits frequently associated with modernization, environmentalism, and conservation spending have the largest component of Earth's biodiversity. This has significant implications for setting policies and priorities for resource management given that biological diversity is rapidly disappearing and cultural traits change slowly. Therefore, we suggest natural resource management adapt to and use characteristics of existing social organization rather than wait for or promote social values associated with conservation spending. Supporting biocultural traditions, engaging leaders to increase conservation commitments, cross-national efforts that complement attributes of cultures, and avoiding interference with nature may work best to conserve nature in collective and hierarchical societies. Spending in modernized nations may be a symbolic response to a symptom of economic development and environmental degradation, and here conservation actions need to ensure that biodiversity is not being lost. © 2016 Society for Conservation Biology.

Full Text Available Faced with fiscal constraints and enormous population pressures, 80% of Chinese nature reserves have employed ecotourism as a support and development strategy. Assessing the actual effects of ecotourism at a nature reserve that has a relatively long history of ecotourism development experience may be instructive for other reserves. Therefore, we take Changbai Mountain Biosphere Reserve (CMBR in northeastern China as a case study, for it is one of the pioneers in embracing ecotourism in China. Personal interviews and informal group discussions were employed to understand local residents' attitudes toward conservation. Factors affecting their attitudes were then analyzed using logistic regression. Results indicate that attitudes held by most farmers are not favorable toward the conservation of the CMBR. It is not ecotourism but rather income from collection of forest products, household crop lands, and migrant labor that actually influences their attitudes. We found that the 1-day-sightseeing tour style, the limited tourism period, and the low level of education and extreme poverty of the local residents, together with existing institutions and lagging regulations make it very difficult for ecotourism to engender local residents' support. We concluded that institutional measures to guarantee local people's sharing in the revenue generated by the reserve, as well as regulations to ensure involvement of the local community in the decision-making process are preconditions for ecotourism to engender local support in China. Providing educational opportunities for children and vocational training for young local residents can also contribute indirectly to enhanced conservation.

Conservation conflict takes place where food production imposes a cost on wildlife conservation and vice versa. Where does conservation impose the maximum cost on production, by opposing the intensification and expansion of farmland? Where does conservation confer the maximum benefit on wildlife, by buffering and connecting protected areas with a habitable and permeable matrix of crop and non-crop habitat? Our aim was to map the costs and benefits of conservation versus production and thus to propose a conceptual framework for systematic conservation planning in agricultural landscapes. World-wide. To quantify these costs and benefits, we used a geographic information system to sample the cropland of the world and map the proportion of non-crop habitat surrounding the cropland, the number of threatened vertebrates with potential to live in or move through the matrix and the yield gap of the cropland. We defined the potential for different types of conservation conflict in terms of interactions between habitat and yield (potential for expansion, intensification, both or neither). We used spatial scan statistics to find 'hotspots' of conservation conflict. All of the 'hottest' hotspots of conservation conflict were in sub-Saharan Africa, which could have impacts on sustainable intensification in this region. Systematic conservation planning could and should be used to identify hotspots of conservation conflict in agricultural landscapes, at multiple scales. The debate between 'land sharing' (extensive agriculture that is wildlife friendly) and 'land sparing' (intensive agriculture that is less wildlife friendly but also less extensive) could be resolved if sharing and sparing were used as different types of tool for resolving different types of conservation conflict (buffering and connecting protected areas by maintaining matrix quality, in different types of matrix). Therefore, both sharing and sparing should be prioritized in hotspots of conflict, in the context of

Camporesi, Matteo; Franchi, Lorenzo; Baccetti, Tiziano; Antonini, Antonino

2006-04-01

The purpose of the present study was to identify the mean configuration of the clinical arch form in a sample of Southern European subjects with ideal natural occlusion by means of Procrustes analysis, and to compare the identified configuration with 10 commercially produced arch forms by means of thin-plate spline (TPS) analysis. The sample comprised the study casts of 50 subjects (26 males and 24 females). The mean age of the sample was 26 years +/- 4 years. All subjects were young Caucasian adults of Southern European ancestry, and presented with an ideal natural occlusion. The three-dimensional (3D) co-ordinates of all dental points (facial axis points) were digitized using a 3D electromagnetic digitizer. The morphometric technique of TPS analysis with permutation tests was used to compare the configurations of landmarks in the various specimens. No sexual dimorphism was found for either upper or lower arch forms when the shape of the arches was assessed independently from size. The commercially available arch form that showed the least, though statistically significant, shape difference with respect to the average calculated configuration was the Brader arch form.

Conservation and non-conservation in general relativity

International Nuclear Information System (INIS)

Bondi, H.

1990-01-01

The difficulties of conservation laws in general relativity are discussed, with special reference to the non-tangible nature of gravitational energy and its transformation into tangible forms of energy. Inductive transfer of energy is marked out as wholly distinct from wave transfer. Slow (adiabatic) changes are utilized to make clear, in the axi-symmetric case, that the mass of an isolated body is conserved irrespective of any local changes (e.g. of shape) and that in inductive transfer the movement of energy between two bodies can readily be traced by the changes in their masses.

Bleeding-Heart Liberals and Hard-Hearted Conservatives: Subtle Political Dehumanization Through Differential Attributions of Human Nature and Human Uniqueness Traits

Directory of Open Access Journals (Sweden)

Jarret T. Crawford

2013-10-01

Full Text Available This research demonstrated that human nature (HN and human uniqueness (HU traits capture the content of Americans’ stereotypes about liberals and conservatives, respectively. Consistent with expectations derived from dehumanization theory, people more strongly associated HN traits with liberals than with conservatives, and more strongly associated HU traits with conservatives than with liberals. A trait × target ideology × perceiver ideology × trait valence interaction suggested that both liberals and conservatives more strongly associated their ingroup with stereotype-consistent positive traits, and their outgroup with stereotype-consistent negative traits. Mediation analyses revealed that outgroup antipathy, but not ingroup liking, explained the relationship between ideology and political outgroup dehumanization. Finally, humanness traits captured subtle differences in political stereotype content not captured with the warmth and competence dimensions derived from the stereotype content model. Together, these results indicate that differential attributions of HN and HU traits capture political stereotype content and function to subtly dehumanize one’s political opponents.

This comprehensive report for the Swiss Federal Office of Energy (SFOE) takes a look at the situation in Switzerland and Europe as far as the liberalisation of the natural gas market is concerned. Comparisons are made between the situation for natural gas and electricity markets. The report discusses the economical and technical characteristics of the gas business such as gas sources, transport, storage and trading as well as the associated investment risks. The gas and electricity supply systems are compared from the supply and demand viewpoints and as far as trading and the increasing of efficiency are concerned. The Swiss gas market is compared with those of selected European countries. Market structures and regulatory aspects are examined and the resulting effects on the market and gas prices are reviewed. The effects of market opening are discussed from both the supplier and consumer points of view

Conservation and restoration of natural building stones monitored through non-destructive X-ray computed tomography

Science.gov (United States)

Jacobs, P. Js; Cnudde, V.

2003-04-01

X-ray computed micro-tomography (μCT) is a promising non-destructive imaging technique to study building materials. μCT analysis provides information on the internal structure and petrophysical properties of small samples (size up to 2 cm diameter and 6 cm height), with to date a maximum resolution of 10 μm for commercial systems (Skyscan 1072). μCT allows visualising and measuring complete three-dimensional object structures without sample preparation. Possible applications of the μCT-technique for the monitoring of natural building stones are multiple: (i) to determine non-destructively porosity based on 3D images, (ii) to visualise weathering phenomena at the μ-scale, (iii) to understand the rationale of weathering processes, (iv) to visualise the presence of waterrepellents and consolidation products, (v) to monitor the protective effects of these products during weathering in order to understand the underlying weathering mechanisms and (vi) to provide advise on the suitability of products for the treatment of a particular rock-type. μCT-technique in combination with micro-Raman spectroscopy could prove to be a powerful tool for the future, as the combination of 3D visualisation and 2D chemical determination of inorganic as well as organic components could provide new insights to optimise conservation and restoration techniques of building materials. Determining the penetration depth of restoration products, used to consolidate or to protect natural building stones from weathering, is crucial if the application of conservation products is planned. Every type of natural building stone has its own petrophysical characteristics and each rock type reacts differently on the various restoration products available on the market. To assess the penetration depth and the effectiveness of a certain restoration product, μCT technology in combination with micro-Raman spectroscopy could be applied. Due to its non-destructive character and its resolution down to

A Generalized Nash-Cournot Model for the North-Western European Natural Gas Markets with a Fuel Substitution Demand Function: The GaMMES Model

International Nuclear Information System (INIS)

Abada, Ibrahim; Briat, Vincent; GABRIEL, Steve A.; MASSOL, Olivier

2011-01-01

This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure description takes into account market power and the demand representation tries to capture the possible fuel substitution that can be made between the consumption of oil, coal, and natural gas in the overall fossil energy consumption. We also take into account long-term contracts in an endogenous way, which makes the model a Generalized Nash Equilibrium problem. We discuss some means to solve such problems. Our model has been applied to represent the European natural gas market and forecast, until 2030, after a calibration process, consumption, prices, production, and natural gas dependence. A comparison between our model, a more standard one that does not take into account energy substitution, and the European Commission natural gas forecasts is carried out to analyze our results. Finally, in order to illustrate the possible use of fuel substitution, we studied the evolution of the natural gas price as compared to the coal and oil prices. (authors)

The widening gap between EU gas production and consumption may require an 87% increase of import volumes between 2006 and 2030, and there are great uncertainties regarding the amounts of gas that can be expected from new suppliers. The potential of increased production from Norway and Algeria is limited; hence, Russia is likely to play a crucial part of meeting the anticipated growing gas demand of the EU. A field-by-field study of 83 giant gas fields shows that the major producing Russian gas fields are in decline, and by 2013 much larger supplies from the Yamal Peninsula and the Shtokman field will be needed in order to avoid a decline in production. Gas from fields in Eastern Siberia and the Far East will mainly be directed to the Asian and Pacific Rim markets, thereby limiting its relevance to the European and CIS markets. As a result, the maximum export increase to the European and CIS markets amounts only to about 45% for the period 2015-2030. The discourse surrounding the EU's dependence on Russian gas should thus not only be concerned with geopolitics, but also with the issue of resource limitations. - Research highlights: {yields}Natural gas production in the Nadym Pur Taz region (Western Siberia) will start to decline within a few years. {yields}New production from the Yamal peninsula is critical to ensure gas exports to Europe. {yields}Additional production in East Siberia and the Far East will not be available for the European market. {yields}Rapid gas demand growth in China might also lead to competition for gas from Western Siberia.

In the Anthropocene, coupled human and natural systems dominate and only a few natural systems remain relatively unaffected by human influence. On the one hand, conservation criteria based on areas of minimal human impact are not relevant to much of the biosphere. On the other hand, conservation criteria based on economic factors are problematic with respect to their ability to arrive at operational indicators of well-being that can be applied in practice over multiple generations. Coupled human and natural systems are subject to economic development which, under current management structures, tends to affect natural systems and cross planetary boundaries. Hence, designing and applying conservation criteria applicable in real-world systems where human and natural systems need to interact and sustainably coexist is essential. By recognizing the criticality of satisfying basic needs as well as the great uncertainty over the needs and preferences of future generations, we sought to incorporate conservation criteria based on minimal human impact into economic evaluation. These criteria require the conservation of environmental conditions such that the opportunity for intergenerational welfare optimization is maintained. Toward this end, we propose the integration of ecological-biological thresholds into decision making and use as an example the planetary-boundaries approach. Both conservation scientists and economists must be involved in defining operational ecological-biological thresholds that can be incorporated into economic thinking and reflect the objectives of conservation, sustainability, and intergenerational welfare optimization. © 2016 Society for Conservation Biology.

Long-term contracts for European gas supply - an empirical analysis of the changing nature of pipeline and LNG-contracts

International Nuclear Information System (INIS)

Neumann, Anne

2005-01-01

As the structure of the European natural gas market is evolving towards more competition and more diverse market structures than before, the nature of the long-term contracts for European natural gas supply is also undergoing change. Experience from other liberalization processes, such as in the U.S. or the UK, suggests that the importance of long-term contracts diminishes over time, but that they remain an important element of supply. In Europe long-term contracts are still considered as a firm basis for investment and financing of capital-intensive infrastructure with a high degree of asset and relationship-specificity. Literature on institutional economics also suggests that long-term contracts act as a device to overcome the ''hold-up'' problem of relationship-specific investments in infrastructure (Klein, Crawford, and Alchian, 1987; Williamson, 1975, 1985). On the other hand, Hartley and Brito (2002) show that more flexible markets also imply a lower degree of asset specificity, thus requiring less fixed contracts. This paper explores the changing nature of long-term contracts for European natural gas supply, with a particular focus on differences between contracts for pipeline gas and liquefied natural gas (LNG). Traditionally, Europe relied on very long-term contracts for pipeline gas (Russia, Norway, Algeria). More recently, increasing LNG supplies are contemplated as a more flexible source of natural gas: The international LNG market is becoming more flexible, LNG can be sourced from a variety of sellers, and the cost of LNG supplies and infrastructure is coming down rapidly (Jensen, 2004). Thus, the evaluation of investing in LNG infrastructure (and the so bought flexibility and possibility of arbitraging profits) may be higher than committing to fixed/predetermined flows of pipeline gas. We ask whether this is reflected in the observed contracts. The paper is based on standard contract theory (Bolton and Dewatripont, 2005). We apply a microeconomic

Application of site-specific natural isotope fractionation (SNIF-NMR) of hydrogen to the characterization of European beers

1985-01-01

More than one hundred samples of European beers have been investigated by the new SNIF-NMR method which is based on 2H NMR at the natural abundance level and enables site-specific natural isotope fractionation factors in ethanol to be determined. The relative (R) and absolute (D/H)sub(i) parameters are shown to be characteristic of the country where the beers are brewed and the observed variations are explained in terms of cereal composition, water resource, and manufacturing processing (fermentation, yeast, temperature cycle). These new parameters find analytical and mechanistic applications in the identification of a beer and in the investigation of a fermentation process. (author)

Genetic Variation in the ND1 Gene and D-loop in Protected and Commercially Exploited European Cisco (Coregonus albula L.) Populations.

The European cisco (Coregonus albula L.) is a species with high environmental requirements. The deterioration of environmental conditions in recent decades has decreased its distribution. Currently the species is conserved by stocking, and the few existing natural populations are at risk of extinction. Therefore, contemporary studies involve not only reporting phenotypic parameters, but also determining the genetic structure of the population. This is an important aspect monitored in the C. albula population, which provides information valuable for proper fishing economy. This study included valuable populations from lakes located in Drawa National Park (DNP) and Wigry National Park (WNP), as well as lakes used for commercial fishing. In order to molecularly characterize the European cisco, the control region and NDl gene were sequenced from 48 individuals from 9 populations from lakes throughout northern Poland. Analysis revealed that populations from two park lakes (Marta, Ostrowieckie) are unique. This was also the case for some sequences originating from Lake Wigry. The mean value of genetic diversity was 0.2% within each region and 0.1-0.3% between the investigated regions. The obtained results demonstrated the necessity to strengthen and protect natural populations of the European cisco, which constitute a valuable element of the European ichthyofauna.

Open access to natural gas pipeline transportation in North America: Lessons for the European internal energy market

1991-01-01

The North American natural gas industry's experience with deregulation is described, with emphasis on the transition to competition and the conditions for viability under open access. Lessons learned from the North American experience are then examined for relevance to the European situation, which is emphasizing greater access to transmission systems. It is found likely that the European proposal will frequently operate only to facilitate negotiations among players already active in the gas market, and is less likely to introduce a large number of independent transactions or new merchants. Challenges for the system will include: government assurance of reliability to domestic gas users who have made arrangements with foreign suppliers; administration of pipeline grids; resolution of competing claims on available transmission services; planning for future suppliers; and impact on investment. 8 refs., 1 fig

Conservation, spillover and gene flow within a network of Northern European marine protected areas.

Directory of Open Access Journals (Sweden)

Mats Brockstedt Olsen Huserbråten

Full Text Available To ensure that marine protected areas (MPAs benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design of a network of northern MPAs where fishing for European lobster (Homarusgammarus is prohibited. First, we demonstrate a high level of residency and survival (50% for almost a year (363 days within MPAs, despite small MPA sizes (0.5-1 km(2. Second, we demonstrate limited export (4.7% of lobsters tagged within MPAs (N = 1810 to neighbouring fished areas, over a median distance of 1.6 km out to maximum 21 km away from MPA centres. In comparison, median movement distance of lobsters recaptured within MPAs was 164 m, and recapture rate was high (40%. Third, we demonstrate a high level of gene flow within the study region, with an estimated F ST of less than 0.0001 over a ≈ 400 km coastline. Thus, the restricted movement of older life stages, combined with a high level of gene flow suggests that connectivity is primarily driven by larval drift. Larval export from the MPAs can most likely affect areas far beyond their borders. Our findings are of high importance for the design of MPA networks for sedentary species with pelagic early life stages.

Key role of European rabbits in the conservation of the Western Mediterranean basin hotspot.

2008-10-01

The Mediterranean Basin is a global hotspot of biodiversity. Hotspots are said to be experiencing a major loss of habitat, but an added risk could be the decline of some species having a special role in ecological relationships of the system. We reviewed the role of European rabbits (Oryctolagus cuniculus) as a keystone species in the Iberian Peninsula portion of the Mediterranean hotspot. Rabbits conspicuously alter plant species composition and vegetation structure through grazing and seed dispersal, which creates open areas and preserves plant species diversity. Moreover, rabbit latrines have a demonstrable effect on soil fertility and plant growth and provide new feeding resources for many invertebrate species. Rabbit burrows provide nest sites and shelter for vertebrates and invertebrates. In addition, rabbits serve as prey for a number of predators, including the critically endangered Iberian lynx (Lynx pardinus) and Spanish Imperial Eagle (Aquila adalberti). Thus, the Mediterranean ecosystem of the Iberian Peninsula should be termed "the rabbit's ecosystem." To our knowledge, this is the first empirical support for existence of a multifunctional keystone species in a global hotspot of biodiversity. Rabbit populations have declined drastically on the Iberian Peninsula, with potential cascading effects and serious ecological and economic consequences. From this perspective, rabbit recovery is one of the biggest challenges for conservation of the Mediterranean Basin hotspot.

Conservation Motivation, Social Equality and Left-Right Ideological Preferences in Western and Eastern Europe.

Science.gov (United States)

Hadarics, Márton

2017-05-01

We investigated how attitudes towards social equality can influence the relationship between conservation motivation (or openness) and personal ideological preferences on the left-right dimension, and how this relationship pattern differs between Western and Central & Eastern European (CEE) respondents. Using data from the European Social Survey (2012) we found that individual-level of conservation motivation reduces cultural egalitarianism in both the Western European and the CEE regions, but its connection with economic egalitarianism is only relevant in the CEE region where it fosters economic egalitarianism. Since both forms of egalitarianism were related to leftist ideological preferences in Western Europe, but in the CEE region only economic egalitarianism was ideologically relevant, we concluded that the classic "rigidity of the right" phenomenon is strongly related to cultural (anti)egalitarianism in Western Europe. At the same time, conservation motivation serves as a basis for the "rigidity of the left" in the post-socialist CEE region, in a great part due to the conventional egalitarian economic views.

Conservation and adaptation to climate change.

Science.gov (United States)

Brooke, Cassandra

2008-12-01

The need to adapt to climate change has become increasingly apparent, and many believe the practice of biodiversity conservation will need to alter to face this challenge. Conservation organizations are eager to determine how they should adapt their practices to climate change. This involves asking the fundamental question of what adaptation to climate change means. Most studies on climate change and conservation, if they consider adaptation at all, assume it is equivalent to the ability of species to adapt naturally to climate change as stated in Article 2 of the United Nations Framework Convention on Climate Change. Adaptation, however, can refer to an array of activities that range from natural adaptation, at one end of the spectrum, to sustainability science in coupled human and natural systems at the other. Most conservation organizations deal with complex systems in which adaptation to climate change involves making decisions on priorities for biodiversity conservation in the face of dynamic risks and involving the public in these decisions. Discursive methods such as analytic deliberation are useful for integrating scientific knowledge with public perceptions and values, particularly when large uncertainties and risks are involved. The use of scenarios in conservation planning is a useful way to build shared understanding at the science-policy interface. Similarly, boundary organizations-organizations or institutions that bridge different scales or mediate the relationship between science and policy-could prove useful for managing the transdisciplinary nature of adaptation to climate change, providing communication and brokerage services and helping to build adaptive capacity. The fact that some nongovernmental organizations (NGOs) are active across the areas of science, policy, and practice makes them well placed to fulfill this role in integrated assessments of biodiversity conservation and adaptation to climate change.

Resilience design: toward a synthesis of cognition, learning, and collaboration for adaptive problem solving in conservation and natural resource stewardship

2014-06-01

Full Text Available Through the resilience design approach, I propose to extend the resilience paradigm by re-examining the components of adaptive decision-making and governance processes. The approach can be divided into three core components: (1 equity design, i.e., the integration of collaborative approaches to conservation and adaptive governance that generates effective self-organization and emergence in conservation and natural resource stewardship; (2 process design, i.e., the generation of more effective knowledge through strategic development of information inputs; and (3 outcome design, i.e., the pragmatic synthesis of the previous two approaches, generating a framework for developing durable and dynamic conservation and stewardship. The design of processes that incorporate perception and learning is critical to generating durable solutions, especially in developing linkages between wicked social and ecological challenges. Starting from first principles based on human cognition, learning, and collaboration, coupled with nearly two decades of practical experience designing and implementing ecosystem-level conservation and restoration programs, I present how design-based approaches to conservation and stewardship can be achieved. This context is critical in helping practitioners and resources managers undertake more effective policy and practice.

Questioning current practice in brown bear, Ursus arctos, conservation in Europe that undervalues taxonomy

Energy Technology Data Exchange (ETDEWEB)

Gippoliti, S.

2016-07-01

The present paper highlights problems associated with the currently–accepted taxonomy of brown bear, Ursus arctos, and their consequences for conservation at the European level. The enormous morphological variability within Ursus arctos is not acknowledged in current taxonomy and conservation practice. Seven major clades are recognized in Ursus arctos by molecular researchers, and although Western Europe maintains most of the populations belonging to the relict Clade 1 brown bear lineage, no reference to this is made in current conservation policy. Furthermore, the tiny population of Apennine brown bears, characterized by unique skull morphology, is not even recognized as a distinct ESU (evolutionari significant unit) by current European legislation, nor is it included in the IUCN Red List. This may have serious consequences as brown bear conservation in Western Europe has been mainly based on restocking and reintroduction programs. (Author)

Strategic conservation planning for the Eastern North Carolina/Southeastern Virginia Strategic Habitat Conservation Team

Alexander-Vaughn, Louise B.; Collazo, Jaime A.; Drew, C. Ashton

2014-01-01

The Eastern North Carolina/Southeastern Virginia Strategic Habitat Conservation Team (ENCSEVA) is a partnership among local federal agencies and programs with a mission to apply Strategic Habitat Conservation to accomplish priority landscape-level conservation within its geographic region. ENCSEVA seeks to further landscape-scale conservation through collaboration with local partners. To accomplish this mission, ENCSEVA is developing a comprehensive Strategic Habitat Conservation Plan (Plan) to provide guidance for its members, partners, and collaborators by establishing mutual conservation goals, objectives, strategies, and metrics to gauge the success of conservation efforts. Identifying common goals allows the ENCSEVA team to develop strategies that leverage joint resources and are more likely to achieve desired impacts across the landscape. The Plan will also provide an approach for ENCSEVA to meet applied research needs (identify knowledge gaps), foster adaptive management principles, identify conservation priorities, prioritize threats (including potential impacts of climate change), and identify the required capacity to implement strategies to create more resilient landscapes. ENCSEVA seeks to support the overarching goals of the South Atlantic Landscape Conservation Cooperative (SALCC) and to provide scientific and technical support for conservation at landscape scales as well as inform the management of natural resources in response to shifts in climate, habitat fragmentation and loss, and other landscape-level challenges (South Atlantic LCC 2012). The ENCSEVA ecoregion encompasses the northern third of the SALCC geography and offers a unique opportunity to apply landscape conservation at multiple scales through the guidance of local conservation and natural resource management efforts and by reporting metrics that reflect the effectiveness of those efforts (Figure 1).

1998-01-01

In summarizing the reasons for the fall of the Roman empire one has found about 210 significant ones. Without too much comparison the Roman empire and the EU natural gas market have similarities in connections between political authorities and the commercial actors in the European natural gas market. The area has consisted of several independent markets with different solutions that from 1988 has been tried integrated in an inner energy market. Several governmental and private actors have interest in this sector and both inhabitants and businesses are affected by alterations in a national natural gas market. This process is not yet finished. The thesis gives a broad description of the topic by including as many as possible of the EU member states. The topic is large and complex and the author has had to make a choice which parts to emphasize. There are chapters on the theoretical basis, the natural gas industry, what factors may explain the relationship between the political authorities and the commercial actors in the national natural gas market in each EU member and how does the EU Commission goals regarding free competition in the energy market affect the relationship between the political authorities and commercial actors in the national natural gas market

Hitherto fungi have rarely been considered in conservation biology, but this is changing as the field moves from addressing single species issues to an integrative ecosystem-based approach. The current emphasis on biodiversity as a provider of ecosystem services throws the spotlight on the vast diversity of fungi, their crucial roles in terrestrial ecosystems, and the benefits of considering fungi in concert with animals and plants. We reviewed the role of fungi in ecosystems and composed an overview of the current state of conservation of fungi. There are 5 areas in which fungi can be readily integrated into conservation: as providers of habitats and processes important for other organisms; as indicators of desired or undesired trends in ecosystem functioning; as indicators of habitats of conservation value; as providers of powerful links between human societies and the natural world because of their value as food, medicine, and biotechnological tools; and as sources of novel tools and approaches for conservation of megadiverse organism groups. We hope conservation professionals will value the potential of fungi, engage mycologists in their work, and appreciate the crucial role of fungi in nature. © 2014 Society for Conservation Biology.

Conservation: Toward firmer ground

Science.gov (United States)

1975-01-01

The following aspects of energy conservation were discussed: conservation history and goals, conservation modes, conservation accounting-criteria, and a method to overcome obstacles. The conservation modes tested fall into one of the following categories: reduced energy consumption, increased efficiency of energy utilization, or substitution of one or more forms of energy for another which is in shorter supply or in some sense thought to be of more value. The conservation accounting criteria include net energy reduction, economic, and technical criteria. A method to overcome obstacles includes (approaches such as: direct personal impact (life style, income, security, aspiration), an element of crisis, large scale involvement of environmental, safety, and health issues, connections to big government, big business, big politics, involvement of known and speculative science and technology, appeal to moral and ethical standards, the transient nature of opportunities to correct the system.

Liberalization of the European gas sector

Natural gas is the fastest growing fossil fuel worldwide, and by 2030, natural gas will replace coal as the second largest fuel, after oil. In particular, the growing use of natural gas in electricity generation rises the demand and changes the image of gas as substitute for light oil for heating. Due to its complete supply dependency, Switzerland will be affected by the European gas market developments. A new market organization, which requires legal and entrepreneurial decisions in Switzerland, emerges from the liberalization process of the energy markets in the European Union. (author)

In the Luangwa Valley, Zambia, persistent poverty and hunger present linked challenges to rural development and biodiversity conservation. Both household coping strategies and larger-scale economic development efforts have caused severe natural resource degradation that limits future economic opportunities and endangers ecosystem services. A model based on a business infrastructure has been developed to promote and maintain sustainable agricultural and natural resource management practices, leading to direct and indirect conservation outcomes. The Community Markets for Conservation (COMACO) model operates primarily with communities surrounding national parks, strengthening conservation benefits produced by these protected areas. COMACO first identifies the least food-secure households and trains them in sustainable agricultural practices that minimize threats to natural resources while meeting household needs. In addition, COMACO identifies people responsible for severe natural resource depletion and trains them to generate alternative income sources. In an effort to maintain compliance with these practices, COMACO provides extension support and access to high-value markets that would otherwise be inaccessible to participants. Because the model is continually evolving via adaptive management, success or failure of the model as a whole is difficult to quantify at this early stage. We therefore test specific hypotheses and present data documenting the stabilization of previously declining wildlife populations; the meeting of thresholds of productivity that give COMACO access to stable, high-value markets and progress toward economic self-sufficiency; and the adoption of sustainable agricultural practices by participants and other community members. Together, these findings describe a unique, business-oriented model for poverty alleviation, food production, and biodiversity conservation.

Biodiversity conservation in agriculture not only relates to the sustainable development of agriculture, but also is an essential part of species conservation. In recent years, the landscape planning approach for biodiversity was highlighted instead of species-focused approach. In this paper, the landscape factors affecting the biodiversity in agriculture were reviewed, and the possible landscape approaches at three different scales for more efficient conservation of biodiversity in agro-landscape were suggested, including: (1) the increase of the proportion of natural or semi-natural habitats in agriculture, diversification of land use or crop pattern, and protection or construction of corridor at landscape level; (2) the establishment of non-cropping elements such as field margin at between-field level; and (3) the application of reasonable crop density, crop distribution pattern and rotation, and intercrop etc. at within-field level. It was suggested that the relevant policies for natural conservation, land use planning, and ecological compensation should be made to apply the landscape approaches for biodiversity conservation at larger scale.

Social-Natural Landscape Reorganised: Swedish Forest-edge Farmers and Wolf Recovery

Directory of Open Access Journals (Sweden)

Sjolander-Lindqvist Annelie

2009-01-01

Full Text Available The politics and the underlying reasons behind the recovery of the Scandinavian wolf population are increasingly contested. According to official policy, wolves should be guaranteed a place in the Swedish natural world. However, the conflict over whether Sweden should host a wolf population sets views on biodiversity and sustainable development against the perspective that local traditions and livelihoods are threatened by the return of wolves. These diverging environmental visions can be seen as competing interests and understandings of nature and wildlife. The desire of the state and nature conservation organisations to implement measures to provide conditions fostering wolf survival are counterbalanced by local action groups and community residents struggling to maintain conditions for conserving summer pastures, opportunities for hunting with sporting dogs, and other recreational activities such as mushroom- and berry-picking. Not only are these activities considered to have high natural and cultural value, the European Union (EU has stated that small-scale farming is important for maintaining the landscape and safeguarding the survival of values associated with ′agri-environmental′ habitats. The conflict between the interest groups is essentially about the access to and use of environmental resources. Squeezed between policies safeguarding wolf populations, preventing cruelty to animals and implementing activities required by the EU agricultural programme, farmers in areas with resident wolf populations have come to take part in processes that may reinforce rural identity.

Biodiversity conservation in a changing climate: a review of threats and implications for conservation planning in Myanmar.

High levels of species richness and endemism make Myanmar a regional priority for conservation. However, decades of economic and political sanctions have resulted in low conservation investment to effectively tackle threats to biodiversity. Recent sweeping political reforms have placed Myanmar on the fast track to economic development-the expectation is increased economic investments focused on the exploitation of the country's rich, and relatively intact, natural resources. Within a context of weak regulatory capacity and inadequate environmental safeguards, rapid economic development is likely to have far-reaching negative implications for already threatened biodiversity and natural-resource-dependent human communities. Climate change will further exacerbate prevailing threats given Myanmar's high exposure and vulnerability. The aim of this review is to examine the implications of increased economic growth and a changing climate within the larger context of biodiversity conservation in Myanmar. We summarize conservation challenges, assess direct climatological impacts on biodiversity and conclude with recommendations for long-term adaptation approaches for biodiversity conservation.

Full Text Available They are many the efforts that are made to conserve the tropical natural forests that are in the world. The communities that inhabit these forests depend directly on the resources of the area. Their priorities are not the commercial exploitation of a product, but in occasions they cause alterations to the environment. The commune «El Pital» is located in the area of reduction of the National Park Machalilla. It presents a native forest with high degree of affectation in their structure due to the entropic local action. The objective of the work is to propose conservation strategies that allow to stop the ecological deterioration of the natural forest of the town and to improve the use of the coastal natural resources. Interviews, shops and exploratory forest inventories were carried out. It confirms that the forest exploitation, the one dismounts and the one clears of vegetation, the cultivations of short cycle and the existence and opening of communication roads, are the main variables that generate bigger tension in the use and handling of the native forest. The positive incidences turned out to be the forest repopulation, gathering of seeds, cultivation of short cycle and the ecotouristic practice in front of the economic movement and services that were the activities that presented more favorable evaluation results for the recovery of the forest and for the development of the community.

Lupinus mariae-josephae is a recently discovered endemism that is only found in alkaline-limed soils, a unique habitat for lupines, from a small area in Valencia region (Spain). In these soils, L. mariae-josephae grows in just a few defined patches, and previous conservation efforts directed towards controlled plant reproduction have been unsuccessful. We have previously shown that L. mariae-josephae plants establish a specific root nodule symbiosis with bradyrhizobia present in those soils, and we reasoned that the paucity of these bacteria in soils might contribute to the lack of success in reproducing plants for conservation purposes. Greenhouse experiments using L. mariae-josephae trap-plants showed the absence or near absence of L. mariae-josephae-nodulating bacteria in “terra rossa” soils of Valencia outside of L. mariae-josephae plant patches, and in other “terra rossa” or alkaline red soils of the Iberian Peninsula and Balearic Islands outside of the Valencia L. mariae-josephae endemism region. Among the bradyrhizobia able to establish an efficient symbiosis with L. mariae-josephae plants, two strains, LmjC and LmjM3 were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural L. mariae-josephae populations, and successful reproduction of the plant was achieved. Interestingly, the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia, and optimal performance was observed in plants inoculated with LmjC, a strain that had previously shown the most efficient behavior under controlled conditions. Our results define conditions for L. mariae-josephae conservation and for extension to alkaline-limed soil habitats, where no other known lupine can thrive. PMID:25019379

Globalization and Europeanization. A Projection on a European Model of Public Administration

Directory of Open Access Journals (Sweden)

Ani Matei

2008-04-01

Full Text Available The specialized studies and literature present moreover and insistently the connection between globalization and Europeanization, more precisely between globalization and a European model of integration, whose features aim to set up a global-type European society. The development of the European model of integration starts with economic elements, it reveals nowadays the Economic and Monetary Union and in perspective it will be structured within a sui generis system of transnational governance. The values of the European model of integration become fundamental values of a social process, with powerful economic and political determinations, aiming the multi-causal interference between individual, community and European construction. This process, remarked increasingly in the specialized literature, being assigned with the name of Europeanization, has got original, functional features in the spectrum of significations of the globalization paradigm. As essential global-type formula, within Europeanization, we shall find models with economic, political or social finality, integrating also a model of administration among the latter ones. When we say administration, we refer to its up dated and adequate contents to the new European developments. This assertion derives from a less economic modality to conceptualize the relationship between globalization and Europeanization, presenting Europeanization more as a political adaptation to globalization and even a political expression of globalization. In this context, the development of a system for European governance on several levels (local, regional, national, intergovernmental and supranational suggests its evolution towards globalization. In fact, the literature specific for Europeanization asserts the fact that the European model has also features with integrative nature related to the supranational and trans-governmental dimensions, as well as features with normative nature in view of harmonization

Position of the American Dietetic Association: food and nutrition professionals can implement practices to conserve natural resources and support ecological sustainability.

It is the position of the American Dietetic Association to encourage environmentally responsible practices that conserve natural resources, minimize the quantity of waste generated, and support the ecological sustainability of the food system-the process of food production, transformation, distribution, access, and consumption. Registered dietitians and dietetic technicians, registered, play various roles in the food system and work in settings where efforts to conserve can have significant effects. Natural resources that provide the foundation for the food system include biodiversity, soil, land, energy, water, and air. A food system that degrades or depletes its resource base is not sustainable. Making wise food purchases and food management decisions entails understanding the external costs of food production and foodservice and how these external costs affect food system sustainability. This position paper provides information, specific action-oriented strategies, and resources to guide registered dietitians and dietetic technicians, registered, in food decision making and professional practice. Food and nutrition professionals also can participate in policy making at the local, state, and national levels, and can support policies that encourage the development of local sustainable food systems. Our actions today have global consequences. Conserving and protecting resources will contribute to the sustainability of the global food system now and in the future.

Conservation and aid: designing more effective investments in natural resource governance reform.

Science.gov (United States)

Nelson, Fred

2009-10-01

Biodiversity conservation outcomes are closely related to the rules and institutions governing resource use. Creating local incentives for conservation through more secure resource tenure is central to conservation outcomes on private and communal lands, where the preponderance of biodiversity occurs. Conservation efforts in sub-Saharan Africa are therefore centrally concerned with governance dynamics and institutional reform processes, such as the decentralization of property rights, and how best to achieve such reforms. Traditional mechanisms for financing conservation efforts in Africa rely heavily on funds channeled through multilateral and bilateral aid agencies. The history of development aid highlights a range of constraints these aid agencies face in terms of working toward more effective resource governance arrangements and promoting reforms. Government aid agencies possess incentives for promoting large-scale and short-term projects that maximize expenditure volumes and tend to define issues in technical rather than political terms. The history of development aid suggests that these and other characteristics of aid agencies impedes their ability to influence governance reform processes and that aid funding may discourage the adoption of reforms. Greater emphasis in African conservation financing needs to be placed on flexible, small-scale investments aligned to local interests and constituencies that prioritize innovation, learning, and experimentation. Additionally, more research is required that explores the linkages between conservation funding, donor decision-making processes, and governance reforms.

Conservation of biodiversity is primary important of today's critically vulnerable environment. Efficient conservation can be possible only with the long-term participation and understanding of the communities. Ritual beliefs of the indigenous people are one of the important tools to understand the local communities and aid the nature conservation. In this paper, we documented contemporary ritual practices and ritual plant uses among the Naxi people and discussed the importance of traditional knowledge on ritual practice in the conservation of plants in the mountains presenting a case study of the Dongba culture. This study was carried out from July in 2013 to July in 2014. To document and analyze the present state of the ritual plant used by the Naxi people we conducted an ethnobotanical survey. We interviewed local people including Dongba priests using the semi-structured questionnaire. During the field study, we participated in the local religious activities to witness the use of different plants in ritual activities of the Naxi people. We interviewed twenty-two key informants and eleven of them were male. All the specimens of documented species were collected and deposited at the herbarium of Kunming Institute of Botany. The survey results revealed the Naxi people possessed sound knowledge of the traditional ritual plants and great diversity of plants used in many of Naxi rituals and festivals. From the survey, we documented 32 ritual plant species belonging to 24 genera of 17 families used in various ritual activities. The ritual plants were grouped into two categories, namely those burned as incense, and those used for decoration. The incense plants like Olea europaea subsp. cuspidata and Pistacia weinmanniifolia were probably promising natural aromatic resource. Plants of genus Quercus were the most frequently used species. The places for ritual activities were diverse, such as the incense burners inside and outside the house and sacred trees at the

This study aims to investigate the perception of local society, especially in the Dayak society in Losarang Indramayu to the importance of the natural resources conservation as subsistence. The research method of this study is qualitative approach to investigate the perception of Dayak society. The result of the research shows that the majority of Dayak local society in Losarang Indramayu is farming rice and vegetables through intercropping. Dayak society of Losarang Indramayu really appreciates to the preservation of natural resources. They believe that if they keep nature, then nature will also be friendly with them. One of the way to save the nature is by doing Pepe ritual, becoming vegetarian, and do not destroy animals around them. Dayak society of Losarang believes that each animal would also like to have the desire to live, taste, and imagination just like humans. Furthermore, they also build a special building that is used to respect all kinds of animal. The building uses bamboo as walls and fibers as roof. In that building, they raise many kinds of farm animal such as chickens, cows, goats, and pigs. By preserving the fauna, they believe that the crops will be abundant every year. By making the society to be aware about the importance of the natural resource and express their aspiration to the policymakers is a step to establish the sustainability of natural resources. Furthermore, in the management of natural resources by the stakeholders, the local society perception needs to be appreciated, understood, and considered.

Implications of human value shift and persistence for biodiversity conservation.

Large-scale change in human values and associated behavior change is believed by some to be the ultimate solution to achieve global biodiversity conservation. Yet little is known about the dynamics of values. We contribute to this area of inquiry by examining the trajectory of values affecting views of wildlife in North America. Using data from a 19-state study in the United States and global data from the Schwartz Value Survey, we explored questions of value persistence and change and the nature of attitudinal responses regarding wildlife conservation issues. We found support, based on subjects' ancestry, for the supposition that domination is a prevalent American value orientation toward wildlife that has origins in European Judeo-Christian traditions. Independent of that effect, we also found indications of change. Modernization is contributing to a shift from domination to mutualism value orientations, which is fostering attitudes less centered on human interests and seemingly more consistent with a biocentric philosophy. Our findings suggest that if value shift could be achieved in a purposeful way, then significant and widespread behavior change believed necessary for long-term conservation success may indeed be possible. In particular, greater emphasis on mutualism values may help provide the context for more collaborative approaches to support future conservation efforts. However, given the societal forces at play, it is not at all clear that human-engineered value shift is tenable. Instead of developing strategies aimed at altering values, it may be more productive to create strategies that recognize and work within the boundaries of existing values. Whereas values appear to be in a period of flux, it will be difficult to predict future trends without a better understanding of value formation and shift, particularly under conditions of rapid social-ecological change. © 2016 Society for Conservation Biology.

Novel urban ecosystems, biodiversity, and conservation

With increasing urbanization the importance of cities for biodiversity conservation grows. This paper reviews the ways in which biodiversity is affected by urbanization and discusses the consequences of different conservation approaches. Cities can be richer in plant species, including in native species, than rural areas. Alien species can lead to both homogenization and differentiation among urban regions. Urban habitats can harbor self-sustaining populations of rare and endangered native species, but cannot replace the complete functionality of (semi-)natural remnants. While many conservation approaches tend to focus on such relict habitats and native species in urban settings, this paper argues for a paradigm shift towards considering the whole range of urban ecosystems. Although conservation attitudes may be challenged by the novelty of some urban ecosystems, which are often linked to high numbers of nonnative species, it is promising to consider their associated ecosystem services, social benefits, and possible contribution to biodiversity conservation. - Highlights: → This paper reviews biotic responses to urbanization and urban conservation approaches. → Cities may be rich in both native and nonnative species. → Urban habitats cannot replace the functionality of natural remnants. → However, even novel urban habitats may harbour rare and endangered species. → Conservation approaches should consider the perspective of novel urban ecosystems. - This paper reviews the ways in which biodiversity is affected by urbanization and argues for expanding urban conservation approaches.

Full Text Available The alpine region is of crucial importance for the European Union; as a result, the Carpathian Convention aims at its sustainable development. Since sustainability implies also conservation through natural protected areas, aimed at including regions representative for the national biogeographical space, this article aims at assessing the efficiency of conservation. The methodology consisted of using spatial metrics applied to Romanian and European data on the natural protected areas, land cover and use and their transitional dynamics. The findings show a very good coverage of the Alpine biogeographical region (98% included in the Convention area, and 43% of it protected within the Convention area and of the ecological region of Carpathian montane coniferous forests (88% included in the Convention area, and 42% of it protected within the Convention area. The dominant land cover is represented by forests (63% within the Convention area, and 70% of the total protected area. The main transitional dynamics are deforestation (covering 50% of all changes area within the Convention area and 46% from the changed area within its protected area and forestations – including afforestation, reforestation and colonization of abandoned agricultural areas by forest vegetation (covering 44% of all changes area within the Convention area and 51% from the changed area within its protected area during 1990-2000 and deforestation (covering 97% of all changes area within the Convention area and 99% from the changed area within its protected area during 1990-2000. The results suggest that the coverage of biogeographical and ecological zones is good, especially for the most relevant ones, but deforestations are a serious issue, regardless of occurring before or after achieving the protection status.

The history of Alberta`s petroleum industry and Energy Resources Conservation Board (ERCB) was told. The conservation movement in Alberta was tracked from 1908 to the founding of the Petroleum and Natural Gas Conservation Board in 1938. Failure of Alberta`s first proration, and the Turner Valley `waste` gas conservation movement occurred during this period. The Leduc discovery and effects of the new regulatory environment on its development were discussed. The natural gas export debate, and the expansion of Alberta`s crude oil market were recounted in detail. The organization and regulation of field development which occurred during the period from 1948 to 1959 was presented. Past actions of the Petroleum and Natural Gas Conservation Board reviewed from today`s perspective. The petroleum industry and the ERCB were said to have been jointly responsible for the creation of a prosperous and confident new Alberta, moving it further and further away from the Canadian economic and political mainstream,, and reinforcing the sense of alienation that began to develop during the preceding agrarian decades. 53 figs., 48 tabs.

Planning nature in urbanized countries. An analysis of monetary and non-monetary impacts of conservation policy scenarios in the Netherlands

Full Text Available Planning and conserving nature areas are challenging tasks in urbanized and intensively used countries like the Netherlands. This paper supports decision making and public policy debate about these tasks in both an empirical and a methodological way. Empirically, we explore policy alternatives by determining the potential consequences of different nature policy scenarios in the Netherlands. Methodologically, we employ a mixed monetary and non-monetary evaluation method known as multi-criteria cost-benefit analysis (MCCBA. We evaluate four new future directions of Dutch nature policy that address four dominant stakeholder demands: biodiversity conservation, the provision of ecosystem services, recreational potential as well as economic gains. To balance compact presentation of evaluation outcomes on the one hand and information richness of results on the other, we distinguish between two impact indicator sets: three “headline” and ten “elaborate” indicators. Using these indicators we discuss the quantitative assessment of the four nature policy scenarios by comparing them to two other scenarios, reflecting the 2010 stand-still baseline situation (2010 as well as a reference policy (Trend. In total, we evaluate six scenarios; four present new directions and two reflect existing or recently (2010 halted practices. Our findings first of all show that even in an urbanized country like the Netherlands, with its intensive competition among land use functions, serious gains in national and international biodiversity are possible. Second, we find that it is doubtful whether stimulating the provision of regulating ecosystem services in a country which applies intensive and profitable agricultural techniques is beneficial. Other countries or areas that are less suitable for intensive agricultural practices may be more logical for this. Finally we demonstrate that increasing urban recreational green space − a common challenge for many urban areas

Other countries or areas that are less suitable for intensive agricultural practices may be more logical for this. Finally we demonstrate that increasing urban recreational green space - a common challenge for many urban areas - can only be achieved at

Traditional means of assessing representativeness of conservation value in protected areas depend on measures of structural biodiversity. The effectiveness of priority conservation areas at representing critical natural capital (CNC) (i.e., an essential and renewable subset of natural capital) remains largely unknown. We analyzed the representativeness of CNC-conservation priority areas in national nature reserves (i.e., nature reserves under jurisdiction of the central government with large spatial distribution across the provinces) in China with a new biophysical-based composite indicator approach. With this approach, we integrated the net primary production of vegetation, topography, soil, and climate variables to map and rank terrestrial ecosystems capacities to generate CNC. National nature reserves accounted for 6.7% of CNC-conservation priority areas across China. Considerable gaps (35.2%) existed between overall (or potential) CNC representativeness nationally and CNC representation in national reserves, and there was significant spatial heterogeneity of representativeness in CNC-conservation priority areas at the regional and provincial levels. For example, the best and worst representations were, respectively, 13.0% and 1.6% regionally and 28.9% and 0.0% provincially. Policy in China is transitioning toward the goal of an ecologically sustainable civilization. We identified CNC-conservation priority areas and conservation gaps and thus contribute to the policy goals of optimization of the national nature reserve network and the demarcation of areas critical to improving the representativeness and conservation of highly functioning areas of natural capital. Moreover, our method for assessing representation of CNC can be easily adapted to other large-scale networks of conservation areas because few data are needed, and our model is relatively simple. © 2017 Society for Conservation Biology.

DOCTRINAL AND IDEOLOGICAL PARADIGM OF THE CONSERVATISM IN THE WESTERN EUROPEAN COUNTRIES

2015-04-01

Full Text Available This paper is an illustration of certain specifications in the conservative discourse in a certain European western countries. Each one of the countries from the western hemisphere has its particular peculiarities that determine the usage of the political operation by the conservative parties. Certainly, the complexity of the conservative ideology study has been enriching with the perception of the most basic practices in the political activity of the right parties in some western countries. This paper consists of a short definition about the conservatism followed by its primary and secondary principles. Then, continues to an individual cases in a three highly developed European countries where as a sample are taken the most significant parties in the conservative and Christian Democrat ideology. The conservatism as a political ideology has been formed in the middle of the XVII century as a resistance towards the shifts and the challenges that were under influence of the enlightenment, industrialization and the urbanization. If the conservatism as a political theory, ideology and practice originates from the countries with foregoing activities, logically emerges a need to study their characteristics. The author’s intention is to represent the traits creating the content of that ideology and activity, what are the distinction marks that would be the most appealing of the certain country, as well as to prove the link with the parties from the conservative family on a European level. The study of the conservatism as a political ideology in the modern ideological- doctrinal spectrum would be certainly impossible if there is no closer look to those paradigms.

The paper presents the results from a stated preference study to address issues concerning the potential for using flag-ship species, such as the Giant Panda, to purchase the property rights for the conservation of natural habitat. The study finds, first, that there is clear WTP for acquiring the property rights for panda habitat. The nature of this demand is found both convincing and logically coherent in that it is an increasing function of land (at a diminishing rate). Secondly, the stu...

2012-01-01

With Gazprom gaining prominence as the major supplier of natural gas in the European Union, the European gas market becomes more politicized. We assume that Gazprom's interest as a state monopolist is not only to maximize profit, but also to seek market power, presumably because this contributes to the geopolitical power of Russia at large. We introduce a modeling tool, so-called strategic delegation games, to analyze the implications of Gazprom's operation in the EU. By way of illustration, we model the case where Gazprom competes against two profit-maximizing rivals: Algerian Sonatrach and Norwegian Statoil. We prove that if Gazprom serves any of a comprehensive type of nonprofit objectives, the outcome is beneficial for the EU's consumers, as Gazprom's behavior shifts volumes up and brings prices down. - Highlights: ► We model the natural gas market in the EU. ► The fact that the major gas supplier Russia/Gazprom has nonprofit incentives is beneficial for EU's consumers. ► The nonprofit incentives increase Russia's market share and decrease the profits of its rivals.

Pipelines to Brussels: Natural gas exporters' strategies in a changing European gas market

International Nuclear Information System (INIS)

Claes, D.H.

1991-01-01

On the political level several different processes will influence the future of the European gas market. The possibilities of large increases in demand due to environmental concerns, and economic development, particularly in Eastern Europe, are beginning to change the buyer's market of the 1980's into a seller's market in the 1990's. Turning to the individual producers, one should not rule out a possible extension of the Dutch export contracts beyond 2010, but the main actors are likely to be the Russian Federation and Norway, as the Algerians are unlikely to stabilize their economy and the political uncertainties. The Russian Federation and Norway seem to be in the best position to capture the demand increase assumed in the next ten to twenty years. However, if the demand forecasts of today turn out to be accurate, there is no reason to worry about future competition between the Russian Federation and Norway. The demand increase would give room for both producers to export large volumes to the European market. Even a conservative estimate of gas demand at about 300 billion m 3 in the year 2010, does give 90 billion m 3 to be filled in by additional deliveries. The ''environmental-scenario'', where a substantial number of coal and oil fired power stations are replaced with gas stations, could easily push demand up to 450 billion m 3 . In this scenario gas would take a larger share of the total energy consumption in Europe. This could make importers more concerned with diversification of their gas imports. On the other hand, the pressure for cleaner fuels could obtain a higher priority than diversification, especially if the political situation stabilizes in the exporting countries: the Russian Federation and Algeria. It could come to a choice between a concentration of gas imports from the Russian Federation and Norway, and the more polluting use of coal and oil. The solution to this choice is not obvious. 26 refs., 11 figs

Marine conservation and accession: the future for the Croatian Adriatic.

Science.gov (United States)

Mackelworth, Peter; Holcer, Draško; Jovanović, Jelena; Fortuna, Caterina

2011-04-01

The European Union (EU) is the world's largest trading bloc and the most influential supra-national organisation in the region. The EU has been the goal for many eastern European States, for Croatia accession remains a priority and underpins many of its national policies. However, entry into the EU requires certain commitments and concessions. In October 2003 the Croatian parliament declared an ecological and fisheries protection zone in the Adriatic. Under pressure the zone was suspended, finally entering into force in March 2008 exempting EU States. There are other marine conflicts between Croatia and the EU, particularly the contested maritime border with Slovenia, and the development of the Croatian fishing fleet in opposition to the Common Fisheries Policy. Conversely, attempts to harmonise Croatian Nature Protection with the EU Habitats Directive, facilitated by pre-accession funding, has galvanised conservation policy. Since 2005 two marine protected areas have been declared, significantly increasing the marine ecosystem under protection. Finally, the development of the Marine Strategy Framework Directive is the latest EU attempt to integrate environmental policy in the maritime realm. This will have an effect not only on member States but neighbouring countries. For marine nature protection to be effective in the region the Adriatic Sea needs to be viewed as a mutually important shared and limited resource not a bargaining chip. Negotiations of the EU and Croatia have been watched closely by the other Balkan States and precedents set in this case have the potential to affect EU expansion to the East.

European Economic Community/the European energy conference (a meeting of the energy ministers of the nine member countries), held at Brussels on 3/27/79, was a continuation of the EEC Council meeting held at Paris on 3/12-13/79. Proposals for measures to be taken by the member countries included support for exploration, especially geophysical prospecting for oil off the east coast of Greenland, at a cost of 3.5 million units of account (UC); modification of the regulations for crude oil distribution among the EEC member countries in case of a supply crisis; a second series of 36 energy-conservation demonstration projects, to cost 15,626,320 UC and be undertaken in 1979-83; and the UK proposal to call for bids on the first series of 17 projects, costing 5,779,000 UC and adopted in Dec. 1978, before discussing the second series. Six of the 36 projects are French; they involve heat pumps and hybrid nuclear-electric vehicles and space-heating systems. A report on the current status of coal projects was given, and problems with fast-breeder reactors were discussed.

Hainan, the largest tropical island in China, belongs to the Indo-Burma biodiversity hotspot. The Changhua watershed is a center of endemism for plants and birds and the cradle of Hainan's main rivers. However, this area has experienced recent and ongoing deforestation and habitat fragmentation. To quantify habitat loss and fragmentation of natural forests, as well as the land-cover changes in the Changhua watershed, we analyzed Landsat images obtained in 1988, 1995, and 2005. Land-cover dynamics analysis showed that natural forests increased in area (97,909 to 104,023 ha) from 1988 to 1995 but decreased rapidly to 76,306 ha over the next decade. Rubber plantations increased steadily throughout the study period while pulp plantations rapidly expanded after 1995. Similar patterns of land cover change were observed in protected areas, indicating a lack of enforcement. Natural forests conversion to rubber and pulp plantations has a general negative effect on biodiversity, primarily through habitat fragmentation. The fragmentation analysis showed that natural forests area was reduced and patch number increased, while patch size and connectivity decreased. These land-cover changes threatened local biodiversity, especially island endemic species. Both natural forests losses and fragmentation should be stopped by strict enforcement to prevent further damage. Preserving the remaining natural forests and enforcing the status of protected areas should be a management priority to maximize the watershed's biodiversity conservation value.

Full Text Available We investigated contemporary and historical influences on the pattern of genetic diversity of European roe deer (Capreolus capreolus. The study was conducted in northeastern Poland, a zone where vast areas of primeval forests are conserved and where the European roe deer was never driven to extinction. A total of 319 unique samples collected in three sampling areas were genotyped at 16 microsatellites and one fragment (610 bp of mitochondrial DNA (mtDNA control region. Genetic diversity was high, and a low degree of genetic differentiation among sampling areas was observed with both microsatellites and mtDNA. No evidence of genetic differentiation between roe deer inhabiting open fields and forested areas was found, indicating that the ability of the species to exploit these contrasting environments might be the result of its phenotypic plasticity. Half of the studied individuals carried an mtDNA haplotype that did not belong to C. capreolus, but to a related species that does not occur naturally in the area, the Siberian roe deer (C. pygargus. No differentiation between individuals with Siberian and European mtDNA haplotypes was detected at microsatellite loci. Introgression of mtDNA of Siberian roe deer into the genome of European roe deer has recently been detected in eastern Europe. Such introgression might be caused by human-mediated translocations of Siberian roe deer within the range of European roe deer or by natural hybridization between these species in the past.

Conservation Action Planning: Lessons learned from the St. Marys River watershed biodiversity conservation planning process

Science.gov (United States)

Patterson, Tamatha A.; Grundel, Ralph

2014-01-01

Conservation Action Planning (CAP) is an adaptive management planning process refined by The Nature Conservancy (TNC) and embraced worldwide as the Open Standards for the Practice of Conservation. The CAP process facilitates open, multi-institutional collaboration on a common conservation agenda through organized actions and quantified results. While specifically designed for conservation efforts, the framework is adaptable and flexible to multiple scales and can be used for any collaborative planning effort. The CAP framework addresses inception; design and development of goals, measures, and strategies; and plan implementation and evaluation. The specific components of the CAP include defining the project scope and conservation targets; assessing the ecological viability; ascertaining threats and surrounding situation; identifying opportunities and designing strategies for action; and implementing actions and monitoring results. In 2007, TNC and a multidisciplinary graduate student team from the University of Michigan's School of Natural Resources and Environment initiated a CAP for the St. Marys River, the connecting channel between Lake Superior and Lake Huron, and its local watershed. The students not only gained experience in conservation planning, but also learned lessons that notably benefited the CAP process and were valuable for any successful collaborative effort—a dedicated core team improved product quality, accelerated the timeline, and provided necessary support for ongoing efforts; an academic approach in preparation for engagement in the planning process brought applicable scientific research to the forefront, enhanced workshop facilitation, and improved stakeholder participation; and early and continuous interactions with regional stakeholders improved cooperation and built a supportive network for collaboration.

European energy security: The future of Norwegian natural gas production

International Nuclear Information System (INIS)

Soederbergh, Bengt; Jakobsson, Kristofer; Aleklett, Kjell

2009-01-01

The European Union (EU) is expected to meet its future growing demand for natural gas by increased imports. In 2006, Norway had a 21% share of EU gas imports. The Norwegian government has communicated that Norwegian gas production will increase by 25-40% from today's level of about 99 billion cubic meters (bcm)/year. This article shows that only a 20-25% growth of Norwegian gas production is possible due to production from currently existing recoverable reserves and contingent resources. A high and a low production forecast for Norwegian gas production is presented. Norwegian gas production exported by pipeline peaks between 2015 and 2016, with minimum peak production in 2015 at 118 bcm/year and maximum peak production at 127 bcm/year in 2016. By 2030 the pipeline export levels are 94-78 bcm. Total Norwegian gas production peaks between 2015 and 2020, with peak production at 124-135 bcm/year. By 2030 the production is 96-115 bcm/year. The results show that there is a limited potential for increased gas exports from Norway to the EU and that Norwegian gas production is declining by 2030 in all scenarios. Annual Norwegian pipeline gas exports to the EU, by 2030, may even be 20 bcm lower than today's level.

Landscape, historic memory and national identity in the beginnings of the policy nature conservation in Spain: from Covadonga to San Juan de la Peña

Directory of Open Access Journals (Sweden)

Jacobo García Álvarez

2013-08-01

Full Text Available This article reflects on the concept of “national landscape” and on the importance of identity symbolic values in the beginning of landscape and nature conservation policy in Spain. The emblematic case of the Montaña de Covadonga (the first National Park created in Spain is examined in more detail. The paper is divided into three main sections. The first one raises some theoretical and general considerations on the role of identity symbolic values within the first steps of nature conservation policies in Spain and other national contexts. Secondly, the cultural-historic processes and discourses which converted the Montaña de Covadonga landscape into a Spanish national symbol and into a site of memory, leading to its declaration as a National Park in 1918, are reviewed. The third section examines the ideological identity disputes and controversies concerning the creation of that National Park, some of which led to the declaration of the Sitio Nacional del Monte de San Juan de la Peña in 1920. The article approaches the creation of the first Spanish Natural Parks as a part of the nationalization policies inspired by the concerns of the “Regeneracionismo”. More precisely, the beginning of natural conservation policy in Spain may be considered as part of the efforts carried out by certain intellectual and political leaders in order to institutionalize new spaces of collective identity grounded in landscape and nature (and, more particularly, in some natural landscapes endowed with a strong historic symbolic meaning as regards to the “birth of the nation”. According to the research conclusions, the ideological controversies raised around the first Spanish Natural Parks can be understood as a reflection of the plurality of competing national conceptions existing in Spain, as well as of the difficulties in reaching a consensus on the country’s national symbols.

Crop wild relatives are wild species that are closely related to crops. They are valuable as potential gene donors for crop improvement and may help to ensure food security for the future. However, they are becoming increasingly threatened in the wild and are inadequately conserved, both in situ and ex situ. Information about the conservation status and utilisation potential of crop wild relatives is diverse and dispersed, and no single agreed standard exists for representing such information; yet, this information is vital to ensure these species are effectively conserved and utilised. The European Community-funded project, European Crop Wild Relative Diversity Assessment and Conservation Forum, determined the minimum information requirements for the conservation and utilisation of crop wild relatives and created the Crop Wild Relative Information System, incorporating an eXtensible Markup Language (XML) schema to aid data sharing and exchange. Crop Wild Relative Markup Language (CWRML) was developed to represent the data necessary for crop wild relative conservation and ensure that they can be effectively utilised for crop improvement. The schema partitions data into taxon-, site-, and population-specific elements, to allow for integration with other more general conservation biology schemata which may emerge as accepted standards in the future. These elements are composed of sub-elements, which are structured in order to facilitate the use of the schema in a variety of crop wild relative conservation and use contexts. Pre-existing standards for data representation in conservation biology were reviewed and incorporated into the schema as restrictions on element data contents, where appropriate. CWRML provides a flexible data communication format for representing in situ and ex situ conservation status of individual taxa as well as their utilisation potential. The development of the schema highlights a number of instances where additional standards-development may

Conservation in Context: A Comparison of Conservation Perspectives in a Mexican Protected Area

Martha Bonilla-Moheno

2012-09-01

Full Text Available The conservation of biodiversity in protected areas depends on the interests and agendas of stakeholders involved in the planning and enforcing of management actions. The challenge, therefore, has been to identify and include the perspectives of multiple participants important to local conservation. This paper describes the social context in which local conservation is conducted in a natural protected area in Yucatan, Mexico. In particular, it examines the agreement and expectations among local stakeholders on the main goals the reserve should achieve. Through participatory observation and semi-structured interviews, we analyzed the perceptions on conservation of the five groups relevant to the area management: 1 local people; 2 conservation government agency; 3 scientists; 4 non-governmental organization, and 5 a tourist agency. All actors agreed that the protected area should fulfill two main goals: i to conserve biodiversity and, ii to improve local welfare and development. In general, ecotourism is perceived as the best option for protecting the forest and promoting local development. Traditional agriculture, on the other hand, is perceived as the main conservation threat, but recognized as a crucial component of local wellbeing. We discuss these results in the context of the Yucatan Peninsula.

Conservation in Mammals of Genes Associated with Aggression-Related Behavioral Phenotypes in Honey Bees.

Directory of Open Access Journals (Sweden)

Hui Liu

2016-06-01

Full Text Available The emerging field of sociogenomics explores the relations between social behavior and genome structure and function. An important question is the extent to which associations between social behavior and gene expression are conserved among the Metazoa. Prior experimental work in an invertebrate model of social behavior, the honey bee, revealed distinct brain gene expression patterns in African and European honey bees, and within European honey bees with different behavioral phenotypes. The present work is a computational study of these previous findings in which we analyze, by orthology determination, the extent to which genes that are socially regulated in honey bees are conserved across the Metazoa. We found that the differentially expressed gene sets associated with alarm pheromone response, the difference between old and young bees, and the colony influence on soldier bees, are enriched in widely conserved genes, indicating that these differences have genomic bases shared with many other metazoans. By contrast, the sets of differentially expressed genes associated with the differences between African and European forager and guard bees are depleted in widely conserved genes, indicating that the genomic basis for this social behavior is relatively specific to honey bees. For the alarm pheromone response gene set, we found a particularly high degree of conservation with mammals, even though the alarm pheromone itself is bee-specific. Gene Ontology identification of human orthologs to the strongly conserved honey bee genes associated with the alarm pheromone response shows overrepresentation of protein metabolism, regulation of protein complex formation, and protein folding, perhaps associated with remodeling of critical neural circuits in response to alarm pheromone. We hypothesize that such remodeling may be an adaptation of social animals to process and respond appropriately to the complex patterns of conspecific communication essential for

The EUNIS (European Union Nature Information System) habitat classification system aims to provide a common European reference set of habitat types within a hierarchical classification, and to cover all terrestrial, freshwater and marine habitats of Europe. The classification facilitates reporting of habitat data in a comparable manner, for use in nature conservation (e.g. inventories, monitoring and assessments), habitat mapping and environmental management. For the marine environment the importance of a univocal habitat classification system is confirmed by the fact that many European initiatives, aimed at marine mapping, assessment and reporting, are increasingly using EUNIS habitat categories and respective codes. For this reason substantial efforts have been made to include information on marine benthic habitats from different regions, aiming to provide a comprehensive geographical coverage of European seas. However, there still remain many concerns on its applicability as only a small fraction of Europe's seas are fully mapped and increasing knowledge and application raise further issues to be resolved. This paper presents an overview of the main discussion and conclusions of a workshop, organised by the MeshAtlantic project, focusing upon the experience in using the EUNIS habitats classification across different countries and seas, together with case studies. The aims of the meeting were to: (i) bring together scientists with experience in the use of the EUNIS marine classification and representatives from the European Environment Agency (EEA); (ii) agree on enhancements to EUNIS that ensure an improved representation of the European marine habitats; and (iii) establish practices that make marine habitat maps produced by scientists more consistent with the needs of managers and decision-makers. During the workshop challenges for the future development of EUNIS were identified, which have been classified into five categories: (1) structure and hierarchy; (2

This paper reviews the effectiveness of conservation interventions that are designed to increase urban sustainability. It presents evidence for an apparent urban-environmental paradox: while the process of urban growth converts natural habitat to other land covers and degrades natural resources and ecosystem function, the increase in human population can increase demand for natural resources and ecosystem services. The fundamental problem that many conservation interventions try to address is that most facets of the environment are common or public goods, and are hence undervalued in decision making (market failure). The paper presents a threefold classification of conservation interventions in cities: conservation in the city (protecting biodiversity), conservation by the city (reducing per capita resource and energy use), and conservation for cities (projects that maintain or enhance ecosystem services). It ends by discussing methods for spatially targeting conservation interventions of all three types and for quantifying the effectiveness of interventions retrospectively. © 2015 New York Academy of Sciences.

Estimating elasticities of demand for natural gas in the European household sector

Energy Technology Data Exchange (ETDEWEB)

Nilsen, Odd Bjarte; Asche, Frank; Tveteras, Ragnar

2005-12-15

This paper analyzes the residential natural gas demand in 12 European countries using a dynamic loglinear demand model, which allows for country-specific elasticity estimates in the short-run and long run. The explanatory variables include a heating degree days index, real prices of natural gas, light fuel oil, electricity, and real private income per capita. Our data set is a country panel with annual observations from 1978 to 2002. Short panel data sets like this represents a challenge for econometric estimation, as standard estimators often provide implausible estimates of elasticities. The demand model is estimated using both homogeneous and heterogeneous estimators, with a particular focus on the shrinkage estimator (an empirical Bayes estimator). The shrinkage short-run own-price and income elasticity tend to be very inelastic, but with greater long-run responsiveness. We provide support for employing a heterogeneous estimator such as the shrinkage estimator. But the empirical results also motivate a further scrutiny of its properties. We also consider the problem of reporting t-statistics of shrinkage estimators in the empirical Bayes (EB) framework and the problem of using the delta method to approximate the elasticities. The delta method biases upward the t-statistics of the shrinkage elasticities. An alternative approach, the bootstrap sampling methods obtained more reliable confidence intervals. We call into question - is the traditional way of constructing confidence intervals or t-statistics of the shrinkage estimator to naive. (Author)

Sustainable Capital? The Neoliberalization of Nature and Knowledge in the European “Knowledge-based Bio-economy”

Directory of Open Access Journals (Sweden)

Theo Papaioannou

2010-09-01

Full Text Available As an EU policy agenda, the “knowledge-based bio-economy” (KBBE emphasizes bio-technoscience as the means to reconcile environmental and economic sustainability. This frames the sustainability problem as an inefficiency to be overcome through a techno-knowledge fix. Here ecological sustainability means a benign eco-efficient productivity using resources which are renewable, reproducible and therefore sustainable. The KBBE narrative has been elaborated by European Technology Platforms in the agri-food-forestry-biofuels sectors, whose proposals shape research priorities. These inform policy agendas for the neoliberalization of both nature and knowledge, especially through intellectual property. In these ways, the KBBE can be understood as a new political-economic strategy for sustainable capital. This strategy invests great expectations for unlocking the productive potential of natural resources through a techno-knowledge fix. Although eco-efficiency is sometimes equated with biological productivity, commercial success will be dependent upon new combinations of “living” and “dead” labour.

Europe's cultural heritage is among the richest in the world, and draws millions of visitors to archeological sites, museums, monuments, castles, and other sites each year. The protection and conservation of European heritage is of utmost importance for our society, not only in order to preserve the European cultural identity, but also because cultural heritage is a wealth creator bringing tourism-related business opportunities on which many communities depend. However, Europe's heritage assets are extremely exposed to climate change and natural hazards, which threatens their integrity and may compromise their value. The goal of the STORM (Safeguarding Cultural Heritage through Technical and Organisational Management) project is to provide critical decision-making tools to European cultural heritage stakeholders affected by climate change and natural hazards. Here, the STORM project will be presented with a focus on climate change and natural hazard risk communication to the involved stakeholders. However, climate change communication is not a one-way process, and discussions with stakeholders are necessary to identify their specific needs. Hence, the STORM concept is tested through pilot site studies in five different countries: the Diocletian Baths in Rome, Italy; the Mellor Heritage site, Manchester, UK; the Roman Ruins of Tróia, Portugal; the Historical Centre of Rethymno on Crete, Greece and Ephesus, Izmir, Turkey. Furthermore, the past and future climatic conditions at the project's pilot sites are analysed in terms of mean state and extreme events (for example temperature and precipitation changes evident from observations and climate scenarios), which will be discussed with regard to their relevance for the local cultural heritage protection based on discussions with the stakeholders.

Use of hydro energetic potential of streams from the aspect of nature conservation on the example of north Slovakia

International Nuclear Information System (INIS)

Zontag, M.

1997-01-01

The paper deals with the exploitation of the small hydroelectric power stations (SHEPS) in the Slovak power system with the aspect of nature conservation on the example of north Slovakia. Decentralized production of water energy can be gained efficiently, and SHEPS may play an important role, for instance, for private sector where these offer higher efficiency and independence from national energy system. However, not respecting limits of the natural environment causes serious damages to ecosystems, usually unrecoverable. Consequently, positive valuation of energy gained from SHEPS as energy ecologically pure is misleading and one-sided. Working such power stations causes serious negative interferences to the natural environment of stream and effects primarily the biotic parts of the ecosystems. The most sensitive and, therefore, also the most affected group of water fauna are fishes. Therefore, this systematic group as an example to explain negative effects of constructing and using of SHEPS was used

Conservation doesn't happen in a vacuum. In recent years, awareness has grown of the relationship of international conservation practice to indigenous peoples and local communities, and especially the links between conservation and human rights. The impacts protected areas can have on rural communities – such as evictions and lost access to natural resources – are now under particular scrutiny. Concern is meanwhile rising over the human rights implications of some climate change mitigation and adaptation measures. But awareness is also growing of the positive contributions of nature conservation to the rights of people to secure their livelihoods, enjoy healthy and productive environments, and live with dignity. International NGOs can play a central role in supporting and promoting conservation actions that respect the rights of indigenous peoples and local communities, and help sustain their livelihoods. Many conservation organisations have long worked towards this. It is vital that they hold to consistent principles and implement measures that ensure their application, so their action on conservation remains accountable, transparent and sustainable.

A strategic model of European gas supply (GASMOD)

International Nuclear Information System (INIS)

Holz, Franziska; Hirschhausen, Christian von; Kemfert, Claudia

2008-01-01

This paper presents a model of the European natural gas supply, GASMOD, which is structured as a two-stage-game of successive natural gas exports to Europe (upstream market) and wholesale trade within Europe (downstream market) and which explicitly includes infrastructure capacities. We compare three possible market scenarios: Cournot competition in both markets, perfect competition in both markets, and perfect competition in the downstream with Cournot competition in the upstream market (EU liberalization). We find that Cournot competition in both markets is the most accurate representation of today's European natural gas market, where suppliers at both stages generate a mark-up at the expense of the final customer (double marginalization). Our results yield a diversified supply portfolio with newly emerging (LNG) exporters gaining market shares. Enforcing competition in the European downstream market would lead to lower prices and higher quantities by avoiding the welfare-reducing effects of double marginalization. Binding infrastructure capacity restrictions strongly influence the results, and we identify bottlenecks mainly for intra-European trade relations whereas transport capacity in the upstream market is globally sufficient in the Cournot scenario.

Biodiversity for billionaires: capitalism, conservation and the role of philanthropy in saving/selling nature.

Science.gov (United States)

Holmes, George

2012-01-01

This article examines the role of philanthropy in conservation as a way of exploring how and why conservation might be becoming more neoliberal. It describes how conservation philanthropy supports capitalism both discursively and in more practical ways. Philanthropy is examined in terms of the two forces considered to be driving the neoliberalization of conservation — the need for capitalism to find new ways of making money, and the desire of conservationists to engage with capitalism as the best way of getting things done. It demonstrates how philanthropy can speak to both of these logics simultaneously, particularly through emerging ideas of philanthrocapitalism, which may be enhancing the neoliberalization of both philanthropy and conservation.

Landscape and Local Controls of Insect Biodiversity in Conservation Grasslands: Implications for the Conservation of Ecosystem Service Providers in Agricultural Environments

Directory of Open Access Journals (Sweden)

Thomas O. Crist

2014-07-01

Full Text Available The conservation of biodiversity in intensively managed agricultural landscapes depends on the amount and spatial arrangement of cultivated and natural lands. Conservation incentives that create semi-natural grasslands may increase the biodiversity of beneficial insects and their associated ecosystem services, such as pollination and the regulation of insect pests, but the effectiveness of these incentives for insect conservation are poorly known, especially in North America. We studied the variation in species richness, composition, and functional-group abundances of bees and predatory beetles in conservation grasslands surrounded by intensively managed agriculture in Southwest Ohio, USA. Characteristics of grassland patches and surrounding land-cover types were used to predict insect species richness, composition, and functional-group abundance using linear models and multivariate ordinations. Bee species richness was positively influenced by forb cover and beetle richness was positively related to grass cover; both taxa had greater richness in grasslands surrounded by larger amounts of semi-natural land cover. Functional groups of bees and predatory beetles defined by body size and sociality varied in their abundance according to differences in plant composition of grassland patches, as well as the surrounding land-cover diversity. Intensive agriculture in the surrounding landscape acted as a filter to both bee and beetle species composition in conservation grasslands. Our results support the need for management incentives to consider landscape-level processes in the conservation of biodiversity and ecosystem services.

Increasing human population interacts with local and global environments to deplete biodiversity and resources humans depend on, thus challenging societal values centered on growth and relying on technology to mitigate environmental stress. Although the need to address the environmental crisis, central to conservation science, generated greener versions of the growth paradigm, we need fundamental shifts in values that ensure transition from a growth-centered society to one acknowledging biophysical limits and centered on human well-being and biodiversity conservation. We discuss the role conservation science can play in this transformation, which poses ethical challenges and obstacles. We analyze how conservation and economics can achieve better consonance, the extent to which technology should be part of the solution, and difficulties the "new conservation science" has generated. An expanded ambition for conservation science should reconcile day-to-day action within the current context with uncompromising, explicit advocacy for radical transitions in core attitudes and processes that govern our interactions with the biosphere. A widening of its focus to understand better the interconnectedness between human well-being and acknowledgment of the limits of an ecologically functional and diverse planet will need to integrate ecological and social sciences better. Although ecology can highlight limits to growth and consequences of ignoring them, social sciences are necessary to diagnose societal mechanisms at work, how to correct them, and potential drivers of social change.

We examine issues to consider when reframing conservation science and practice in the context of global change. New framings of the links between ecosystems and society are emerging that are changing peoples' values and expectations of nature, resulting in plural perspectives on conservation. Reframing conservation for global change can thus be regarded as a stage in the evolving relationship between people and nature rather than some recent trend. New models of how conservation links with transformative adaptation include how decision contexts for conservation can be reframed and integrated with an adaptation pathways approach to create new options for global-change-ready conservation. New relationships for conservation science and governance include coproduction of knowledge that supports social learning. New processes for implementing adaptation for conservation outcomes include deliberate practices used to develop new strategies, shift world views, work with conflict, address power and intergenerational equity in decisions, and build consciousness and creativity that empower agents to act. We argue that reframing conservation for global change requires scientists and practitioners to implement approaches unconstrained by discipline and sectoral boundaries, geopolitical polarities, or technical problematization. We consider a stronger focus on inclusive creation of knowledge and the interaction of this knowledge with societal values and rules is likely to result in conservation science and practice that meets the challenges of a postnormal world. © 2017 The Authors.

Mexico's wetlands support a tremendous biological diversity and provide significant natural resource benefits to local communities. Because they are also critical stopover and wintering grounds for much of North America's waterfowl and other migratory birds, Mexico has become an important participant in continental efforts to conserve these resources through the North American Wetlands Conservation Act. Funding from the Act has supported partnerships in a number of Mexico's priority wetlands to conduct data analyses and dissemination, mapping, environmental education, wetland restoration, development of sustainable economic alternatives for local people, and reserve planning and management. These partnerships, with the close involvement of Mexico's Federal Government authority, the Instituto Nacional de Ecologia, have advanced conservation in a uniquely Mexican model that differs from that employed in the United States and Canada.

European social model and the harmonization of Macedonian labour legislation with the European Union community labour law

Directory of Open Access Journals (Sweden)

Kalamatiev Todor

2014-01-01

Full Text Available The European integration process accompanied by the harmonization of the EU member states' legislation will inevitably lead to the establishment of a European social model which has a 'sui generis' legal nature. European social model forms a part of the common legal heritage of the European countries and it can be defined as a system of values that include democracy and individual rights, free collective bargaining, market economy, equal opportunities for all, and social protection and solidarity. Subject of analysis in this paper are both, the essential components of the European social model such as: the social 'acquis communautaire' and the European industrial relations. The social 'acquis communautaire' is an integral part of the general 'acquis communautaire' and it encompasses the regulations arising from the primary and secondary labour law legislation of the EU, decisions of the European Court of Justice and other legal measures of the European Union with a binding or non-binding legal nature. European industrial relations encompass the key features of the European trade union models as well as the types of social dialogue in different EU member states. This paper pays attention to a profound elaboration of the harmonization of two EU labour law directives with the Macedonian employment legislation. The first Directive (Directive 91/533/EEC of 14 October 1991 on an employers' obligation to inform employees of the conditions applicable to the contract or employment relationship may be classified in the field of individual employment relations, while the second one (Directive 2002/14/EC of 11 March 2002 establishing a general framework for informing and consulting employees in the European Community can be subsumed within the field of collective employment relations. Finally, the authors illustrate the advantages and disadvantages of the Macedonian labour legislation in the process of harmonization with the relevant EU directives

Evaluating local benefits from conservation in Nepal's Annapurna Conservation Area.

Science.gov (United States)

Spiteri, Arian; Nepal, Sanjay K

2008-09-01

Protected areas are integral to the global effort to conserve biodiversity, and, over the past two decades, protected area managers have begun to recognize that conservation objectives are next to impossible to achieve without considering the needs and concerns of local communities. Incentive-based programs (IBPs) have become a favored approach to protected area management, geared at fostering local stewardship by delivering benefits tied to conservation to local people. Effective IBPs require benefits to accrue to and be recognized by those experiencing the greatest consequences as a result of the protected area, and those likely to continue extractive activities if their livelihood needs are compromised. This research examines dispersal of IBP benefits, as perceived by local residents in Nepal's Annapurna Conservation Area. Results reported here are based on questionnaire interviews with 188 households conducted between September and December 2004. Results indicate that local residents primarily identify benefits from social development activities, provisions for resource extraction, and economic opportunities. Overall, benefits have been dispersed equally to households in villages on and off the main tourist route, and regardless of a household's participation in tourism. However, benefits are not effectively targeted to poorer residents, those highly dependent on natural resources, and those experiencing the most crop damage and livestock loss from protected wildlife. This article provides several suggestions for improving the delivery of conservation incentives.

The effect of gamma radiation was evaluated on the microbiological population, soluble solids content, acidity, p H and ascorbic acid content of natural orange juice. Microbial activity may cause deterioration of orange juice. Irradiation is a process of food conservation which eliminates microorganisms. nevertheless radiation may affect some characteristics of irradiated food. The experimental design was a 4 x 5 factorial scheme, including control and 3 rates of irradiation (2.0, 4.0 and 6.0 kGy) and 5 storage periods (1, 7, 14, 21 and 28 days), with 2 replicates. Samples of juice were extracted from variety Pera oranges and irradiated at a rate of 2.0 kGy/h ({sup 60} Cobalt) and thereafter stored at 5 +- 3 deg C. Results showed small changes in soluble solids content, acidity and p H, for all treatments. The ratio soluble solids/acidity was also determined and showed little variation for all treatments. There was a reduction on ascorbic acid content of the orange juice with increased radiation dosage and storage time. Gamma radiation was effective in reducing the microbiological population of the juice. (author)

Biodiversity offsetting and restoration under the European Union Habitats Directive: balancing between no net loss and deathbed conservation?

Directory of Open Access Journals (Sweden)

Hendrik Schoukens

2016-12-01

Full Text Available Biodiversity offsets have emerged as one of the most prominent policy approaches to align economic development with nature protection across many jurisdictions, including the European Union. Given the increased level of scrutiny that needs to be applied when authorizing economic developments near protected Natura 2000 sites, the incorporation of onsite biodiversity offsets in project design has grown increasingly popular in some member states, such as the Netherlands and Belgium. Under this approach, the negative effects of developments are outbalanced by restoration programs that are functionally linked to the infrastructure projects. However, although taking into consideration that the positive effects of onsite restoration measures leads to more leeway for harmful project development, the EU Court of Justice has recently dismissed the latter approaches for going against the preventative underpinnings of the EU Habitats Directive. Also, the expected beneficial outcomes of the restoration efforts are uncertain and thus cannot be relied upon in an ecological assessment under Article 6(3 of the Habitats Directive. Although biodiversity offsets can still be relied upon whenever application is being made of the derogation clause under Article 6(4 of the Habitats Directive, they cannot be used as mitigation under the generic decision-making process for plans and programs liable to adversely affect Natura 2000 sites. We outline the main arguments pro and contra the stance of the EU Court of Justice with regards to the exact delineation between mitigation and compensation. The analysis is also framed in the ongoing debate on the effectiveness of the EU nature directives. Although ostensibly rigid, it is argued that the recent case-law developments are in line with the main principles underpinning biodiversity offsetting. Opening the door for biodiversity offsetting under the Habitats Directive will certainly not reverse the predicament of the EU

Combining natural history collections with fisher knowledge for community-based conservation in Fiji.

2014-01-01

Harnessing the traditional ecological knowledge (TEK) of local communities has the potential to enhance conservation planning in developing regions. Marine protected areas (MPAs) that incorporate traditional beliefs about reef tenure are generally more successful in reaching conservation goals and ensuring the participation of local fishermen on vulnerable tropical reef systems. Fiji possesses a unique system of traditional reef management in which local clans or villages, called mataqali, control individual units of a reef, known as qoliqoli, and make independent management decisions based on traditional beliefs and conservation concerns. This is an example of a system, known as customary marine tenure, which has attracted interest from conservation scientists hoping to set up MPAs in vulnerable regions. As one example of this grassroots participation, Nagigi village on the Fijian island of Vanua Levu has expressed interest in setting up an MPA in part of its qoliqoli because of concerns about overfishing. In response to this interest, we took a two-pronged approach to assessing Nagigi's fishery status and conservation needs, first conducting a fishery-independent species survey using destructive sampling and then focusing on fisheries targets identified through fisher interviews. These interviews allowed us to identify heavily targeted species, assess villagers' understanding of reef dynamics over 30 or 40 years of fisheries expansion, and evaluate village support and expectations for a proposed conservation program. Based on our findings we recommend a temporary closure to be in effect for at least three years, allowing one of the more important fishery targets, Lethrinus harak (Forsskål, 1775; Lethrinidae), to complete at least one generation within the reserve. The methodology of matching the proposed marine protected area with the life histories and ecologies of heavily targeted species identified through fisherman and -woman interviews can offer a template

Primarily, it is essential to note that right up to the present day no juridical definition or legal recognition concerning the profession of the conservator/restorer exists in most European countries. This in turn means an almost complete lack of specific regulations covering any anticipated conservation–restoration activities and the failure to stipulate the quality of these activities. The absolute need for qualified professionals, for a legal status, for an evaluation of the dynamics in a...

Full Text Available In the markets of the European Union (EU the presence of food imported from non-European countries such as Asia, Africa and America is increasingly more widespread. Non-European countries, indeed, are much more competitive in terms of prices compared to European countries. For these reasons, EU has issued important laws. The purpose of this study was to assess the effectiveness of these regulations, estimating the levels of microbiological and chemical contamination of food samples of 91 different matrices imported from third countries. The microbiological methods used are those required by the UNI EN ISO, while for the determination of chemical parameters validated methods according to the Standard UNI EN ISO 16140:2003 were used. Our investigation revealed qualitative or quantitative microbial contamination in 23 out of 91 samples analysed (25.2%. We found high total microbial loads in alimentary conserves, multiple bacterial contamination (Salmonella thiphymurium, Escherichia coli and Vibrio alginolyticus and viral contamination (Norovirus in shellfish of the species Cassostrea gigas, and the presence of other pathogens in various products such as hamburgers (Yersinia enterocolitica, frozen fish (Listeria monocytogenes and honey (Bacillus cereus. With regard to chemical contamination, 24 samples of different food products were analysed. In 9 samples (37.5%, the levels of the following substances exceeded the permitted limits: histamine (fish conserves, mercury (crab meat, cadmium (crab meat and fish conserves, lead (cheese and honey and polyphosphates (chicken meat. Despite the limited number of samples analysed, these data prompt reflection on the need to implement a more detailed and rigorous activity of monitoring and control in order to guarantee adequate levels of safety with regard to the consumption of foodstuffs imported into the EU from non-European countries.

Successful conservation of a threatened Maculinea butterfly.

2009-07-03

Globally threatened butterflies have prompted research-based approaches to insect conservation. Here, we describe the reversal of the decline of Maculinea arion (Large Blue), a charismatic specialist whose larvae parasitize Myrmica ant societies. M. arion larvae were more specialized than had previously been recognized, being adapted to a single host-ant species that inhabits a narrow niche in grassland. Inconspicuous changes in grazing and vegetation structure caused host ants to be replaced by similar but unsuitable congeners, explaining the extinction of European Maculinea populations. Once this problem was identified, UK ecosystems were perturbed appropriately, validating models predicting the recovery and subsequent dynamics of the butterfly and ants at 78 sites. The successful identification and reversal of the problem provides a paradigm for other insect conservation projects.

Local Responses to Participatory Conservation in Annapurna Conservation Area, Nepal

Khadka, Damodar; Nepal, Sanjay K.

2010-02-01

Biodiversity conservation has undergone a profound change in philosophy, policies and management approaches over the last forty years. The traditional top-down approach to nature protection has been widely criticized for failing to include critical social elements in management practices, and is being gradually replaced by a slew of participatory strategies under the rubric of bottom-up conservation. The new approach recognizes local communities as key partners in wildlife management and seeks their participation in social development and biodiversity conservation. However, every social context is different in its structure and functions, and in the way social groups respond to calls for participation. In order to gain a better understanding of the approach and the barriers encountered in its implementation, a questionnaire survey of 188 households was employed in the communities of the Upper Mustang extension of Annapurna Conservation Area (ACA) in Nepal. The study provides a comparative analysis of community participation and its barriers between Non-Tourist (NT) and Tourist (TV) villages. The results revealed important differences between the two groups in terms of their participation in community programs, barriers to participation, and perception of benefits from participation. Owing to their distinct spatial, demographic and attitudinal differences, the two village groups have their own sets of needs, values and motivation factors which cannot be generalized and treated as such. The research clearly identifies the need for the conservation agency to be creative in devising strategies and initiatives appropriate to specific social groups so as to optimize their input in participatory conservation.

Decentralizing conservation and diversifying livelihoods within Kanchenjunga Conservation Area, Nepal.

Parker, Pete; Thapa, Brijesh; Jacob, Aerin

2015-12-01

To alleviate poverty and enhance conservation in resource dependent communities, managers must identify existing livelihood strategies and the associated factors that impede household access to livelihood assets. Researchers increasingly advocate reallocating management power from exclusionary central institutions to a decentralized system of management based on local and inclusive participation. However, it is yet to be shown if decentralizing conservation leads to diversified livelihoods within a protected area. The purpose of this study was to identify and assess factors affecting household livelihood diversification within Nepal's Kanchenjunga Conservation Area Project, the first protected area in Asia to decentralize conservation. We randomly surveyed 25% of Kanchenjunga households to assess household socioeconomic and demographic characteristics and access to livelihood assets. We used a cluster analysis with the ten most common income generating activities (both on- and off-farm) to group the strategies households use to diversify livelihoods, and a multinomial logistic regression to identify predictors of livelihood diversification. We found four distinct groups of household livelihood strategies with a range of diversification that directly corresponded to household income. The predictors of livelihood diversification were more related to pre-existing socioeconomic and demographic factors (e.g., more landholdings and livestock, fewer dependents, receiving remittances) than activities sponsored by decentralizing conservation (e.g., microcredit, training, education, interaction with project staff). Taken together, our findings indicate that without direct policies to target marginalized groups, decentralized conservation in Kanchenjunga will continue to exclude marginalized groups, limiting a household's ability to diversify their livelihood and perpetuating their dependence on natural resources.

Europe's Common Market offers an interesting challenge to its member countries' natural gas distribution system operators in that which regards the creation of a European-wide natural gas control board, and European standardization and regulatory committees contemporaneously guaranteeing a free market for suppliers, as well as, consumer protection. Relative legislation and normatives activities will be deemed the responsibility of the European administrative structure and the the European Normatives Committee respectively. This paper briefly illustrates the progress that has been accomplished thus far in the standardization of technical aspects. Focus is on the certification of natural gas distribution system constructors

Full Text Available In wheat, remobilization of nitrogen absorbed before anthesis and regulation of monocarpic senescence is a major issue in breeding for nutrient use efficiency. We identified natural variants of NAM-A1, a gene having the same role as its well-characterized homoeolog NAM-B1, a NAC transcription factor associated with senescence kinetics and nutrient remobilization to the grain. Differences in haplotype frequencies between a worldwide core collection and a panel of European elite varieties were assessed and discussed. Moreover, hypotheses for the loss of function of the most common haplotype in elite European germplasm are discussed.

The following aspects are examined: To what extent are regulations on security of the natural gas supply provided in the German and European law. Which actors have the responsibility for the security of supply? What are the weaknesses in the legal arrangement of security of supply? The contribution also reports on the increasing importance of the EU as an actor of guarantee. The contribution of the EU to the security of supply in the supply of natural gas also is analysed.

Climate-smart conservation: putting adaption principles into practice

Stein, Bruce A.; Glick, Patty; Edelson, Naomi; Staudt, Amanda

2014-01-01

Climate change already is having significant impacts on the nation’s species and ecosystems, and these effects are projected to increase considerably over time. As a result, climate change is now a primary lens through which conservation and natural resource management must be viewed. How should we prepare for and respond to the impacts of climate change on wildlife and their habitats? What should we be doing differently in light of these climatic shifts, and what actions continue to make sense? Climate-Smart Conservation: Putting Adaptation Principles into Practice offers guidance for designing and carrying out conservation in the face of a rapidly changing climate. Addressing the growing threats brought about or accentuated by rapid climate change requires a fundamental shift in the practice of natural resource management and conservation. Traditionally, conservationists have focused their efforts on protecting and managing systems to maintain their current state, or to restore degraded systems back to a historical state regarded as more desirable. Conservation planners and practitioners will need to adopt forward-looking goals and implement strategies specifically designed to prepare for and adjust to current and future climatic changes, and the associated impacts on natural systems and human communities—an emerging discipline known as climate change adaptation. The field of climate change adaptation is still in its infancy. Although there is increasing attention focused on the subject, much of the guidance developed to date has been general in nature, concentrating on high-level principles rather than specific actions. It is against this backdrop that this guide was prepared as a means for helping put adaptation principles into practice, and for moving adaptation from planning to action.

Tourism and conservation in Madagascar: The importance of Andasibe National Park

David Newsome

2014-06-01

Full Text Available Madagascar is renowned for high levels of biodiversity and endemism. As a result of its unique flora and fauna, as well as the high levels of human threat to the environment, such as illegal clearing, hunting and political instability, it is a critical global conservation priority. Andasibe–Mantadia National Park in eastern Madagascar is one of the most popular protected areas visited by tourists. Observations carried out in 2011 showed that even though there were some negative impacts associated with natural-area tourism, the benefits to both the local communities and associated biological conservation outweighed the negatives. Natural-area tourism at Andasibe is well organised, with many local guide associations having partnerships with international organisations and 50% of park fees going directly to local communities. Forest loss is a widespread problem in Madagascar, but at Andasibe the forest is valued for its ecological function and as a generator of profits from natural-area tourism. Exploitation of the park was not observed. Andasibe is an example of how conservation and natural-area tourism can work together in Madagascar for the benefit of local communities and the environment. However, with the current unstable political climate and lack of adequate wider tourism and conservation planning frameworks, awakening to its potential as a leading conservation tourism destination will not be a simple task. Conservation implications: This research demonstrated that ecotourism can be an effective means of achieving conservation objectives, whilst, at the same time, improving the livelihoods of local people. We caution, however, that governments can do a lot more to encourage and support the nexus between tourism and conservation.

European future natural gas demand and supply diversification: key issues for Central and Eastern Europe

International Nuclear Information System (INIS)

Mueller-Elschner, E.

1996-01-01

After the breakdown of the former Soviet Union and the COMECON the demarcation line between western Europe and central/eastern Europe has disappeared. The central and eastern European economies as a whole and their gas industries as well as the western European gas companies are preparing for the future enlarged market in creating the prerequisites to participate successfully in such a market and to seize the opportunities this market is offering. The framework for this future European Gas Market has to be created now. The European gas industries and gas markets are in transition and are in a process of reshaping, with the following challenges: (1) In Central and Eastern European countries: To complete the privatization and restructuring process from centrally-planned economies to market-oriented structures with deregulated prices, market-oriented tariff systems and new legal and regulatory frameworks. These are the essential prerequisites for an integration of the central and eastern European countries into a single European gas market and the basis for an effective and successful trans border gas co-operation between east and west. (2) In western European countries: To pursue nearly similar processes of restructuring which are underway: privatization by reducing state participation and influence in gas and energy companies, with the accent on liberalization and deregulation of market structures with fewer market entry barriers, and more competition by reducing the influence of state or private monopolies. Gas companies are undertaking cost-efficiency measures to be prepared to meet the requirements of more competitive market structures and also of a more advanced internationalized gas business. The fundamental rules on which western European gas industries based their operations up to now have to be reconsidered. The old western European structures which have developed under the shelter of governmental protection are under pressure from several sources. EU energy

Conservation organizations rely on conservation easements for diverse purposes, including protection of species and natural communities, working forests, and open space. This research investigated how perpetual conservation easements incorporated property rights, responsibilities, and options for change over time in land management. We compared 34 conservation easements held by one federal, three state, and four nonprofit organizations in Wisconsin. They incorporated six mechanisms for ongoing land management decision-making: management plans (74 %), modifications to permitted landowner uses with discretionary consent (65 %), amendment clauses (53 %), easement holder rights to conduct land management (50 %), reference to laws or policies as compliance terms (47 %), and conditional use permits (12 %). Easements with purposes to protect species and natural communities had more ecological monitoring rights, organizational control over land management, and mechanisms for change than easements with general open space purposes. Forestry purposes were associated with mechanisms for change but not necessarily with ecological monitoring rights or organizational control over land management. The Natural Resources Conservation Service-Wetland Reserve Program had a particularly consistent approach with high control over land use and some discretion to modify uses through permits. Conservation staff perceived a need to respond to changing social and ecological conditions but were divided on whether climate change was likely to negatively impact their conservation easements. Many conservation easements involved significant constraints on easement holders' options for altering land management to achieve conservation purposes over time. This study suggests the need for greater attention to easement drafting, monitoring, and ongoing decision processes to ensure the public benefits of land conservation in changing landscapes.

A Note on Weak Solutions of Conservation Laws and Energy/Entropy Conservation

Science.gov (United States)

Gwiazda, Piotr; Michálek, Martin; Świerczewska-Gwiazda, Agnieszka

2018-03-01

A common feature of systems of conservation laws of continuum physics is that they are endowed with natural companion laws which are in such cases most often related to the second law of thermodynamics. This observation easily generalizes to any symmetrizable system of conservation laws; they are endowed with nontrivial companion conservation laws, which are immediately satisfied by classical solutions. Not surprisingly, weak solutions may fail to satisfy companion laws, which are then often relaxed from equality to inequality and overtake the role of physical admissibility conditions for weak solutions. We want to answer the question: what is a critical regularity of weak solutions to a general system of conservation laws to satisfy an associated companion law as an equality? An archetypal example of such a result was derived for the incompressible Euler system in the context of Onsager's conjecture in the early nineties. This general result can serve as a simple criterion to numerous systems of mathematical physics to prescribe the regularity of solutions needed for an appropriate companion law to be satisfied.

Combining natural history collections with fisher knowledge for community-based conservation in Fiji.

Directory of Open Access Journals (Sweden)

Abigail S Golden

Full Text Available Harnessing the traditional ecological knowledge (TEK of local communities has the potential to enhance conservation planning in developing regions. Marine protected areas (MPAs that incorporate traditional beliefs about reef tenure are generally more successful in reaching conservation goals and ensuring the participation of local fishermen on vulnerable tropical reef systems. Fiji possesses a unique system of traditional reef management in which local clans or villages, called mataqali, control individual units of a reef, known as qoliqoli, and make independent management decisions based on traditional beliefs and conservation concerns. This is an example of a system, known as customary marine tenure, which has attracted interest from conservation scientists hoping to set up MPAs in vulnerable regions. As one example of this grassroots participation, Nagigi village on the Fijian island of Vanua Levu has expressed interest in setting up an MPA in part of its qoliqoli because of concerns about overfishing. In response to this interest, we took a two-pronged approach to assessing Nagigi's fishery status and conservation needs, first conducting a fishery-independent species survey using destructive sampling and then focusing on fisheries targets identified through fisher interviews. These interviews allowed us to identify heavily targeted species, assess villagers' understanding of reef dynamics over 30 or 40 years of fisheries expansion, and evaluate village support and expectations for a proposed conservation program.

Despite ambitious biodiversity policy goals, less than a fifth of the European Union's (EU) legally protected species and habitats show a favorable conservation status. The recent EU biodiversity strategy recognizes that climate change adds to the challenge of halting biodiversity loss, and that an optimal distribution of financial resources is needed. Here, we analyze recent EU biodiversity funding from a climate change perspective. We compare the allocation of funds to the distribution of both current conservation priorities (within and beyond Natura 2000) and future conservation needs at the level of NUTS-2 regions, using modelled bird distributions as indicators of conservation value. We find that funding is reasonably well aligned with current conservation efforts but poorly fit with future needs under climate change, indicating obstacles for implementing adaptation measures. We suggest revising EU biodiversity funding instruments for the 2014-2020 budget period to better account for potential climate change impacts on biodiversity.

Evidence indicates that, despite some critical successes, current conservation approaches are not slowing the overall rate of biodiversity loss. The field of synthetic biology, which is capable of altering natural genomes with extremely precise editing, might offer the potential to resolve some intractable conservation problems (e.g., invasive species or pathogens). However, it is our opinion that there has been insufficient engagement by the conservation community with practitioners of synthetic biology. We contend that rapid, large-scale engagement of these two communities is urgently needed to avoid unintended and deleterious ecological consequences. To this point we describe case studies where synthetic biology is currently being applied to conservation, and we highlight the benefits to conservation biologists from engaging with this emerging technology.

Challenging the Concept of Natural Distributions: Global Change Turns Trees Into Weeds

Science.gov (United States)

Gleadow, R.; O'Leary, B.; Burd, M.

2015-12-01

National parks and nature reserves are set aside to preserve certain ecosystems, reflecting species distributions at a moment in time. Changing climate and fire dynamics can mean that the species most suited to that area are different, leading new tree species to 'invade' the conservation areas. Pittosporum undulatum is an invasive tree native tree species with a natural range from southeast Queensland to Eastern Victoria, Australia. Soon after European settlement this species became a popular ornamental tree in gardens and was planted outside of its natural range across the continent and introduced to the USA (where it is known as Victorian Box), the Hawaiian Islands, Jamaica, southern Africa and the Azores. The reason this is important is because high density of P. undulatum lead to reduced biodiversity and often the complete suppression of regeneration of exiting forest trees. In Australia, changes in fire dynamics have played a major part in its in dominance. New strategies for forest management were proposed by Gleadow an Ashton in the 1980s, but lack of action has led us to predict that the entire Dandenong Ranges, near Melbourne, will be invaded within 25 years resulting in the loss of a major recreational and conservation area. This is a model of the type of problems that can be expected as the climate envelope for species changes in the coming century, challenging the very concept of a "native ".

Full Text Available Given Winston Churchill’s influence and achievement as a writer, historian, adventurer, soldier, artist, and politician, his participation in the European integration process is crucial to understanding the entire scope of the project in its origins. Churchill was a fundamental voice promoting the Franco-British Union, a promoter of the European Communities, and an active participant of the Congress of Europe, embryo of the Council of Europe. This article analyzes Churchill’s view of European integration through his political speeches, in particular those delivered in Zurich and in The Hague, his ideas about the League of Nations and the United Nations, his understanding of the British Empire, and the special relations between the UK and the USA. His participation in the process of uniting Europe in its early stages provides us with essential information about the original plans for the creation of a united Europe and understanding the traditional British approach to the EU, including the current position of the conservative government led by Cameron.

The snow leopard (Panthera uncia) inhabits the rugged mountains in 12 countries of Central Asia, including the Tibetan Plateau. Due to poaching, decreased abundance of prey, and habitat degradation, it was listed as endangered by the International Union for Conservation of Nature in 1972. Current conservation strategies, including nature reserves and incentive programs, have limited capacities to protect snow leopards. We investigated the role of Tibetan Buddhist monasteries in snow leopard conservation in the Sanjiangyuan region in China's Qinghai Province on the Tibetan Plateau. From 2009 to 2011, we systematically surveyed snow leopards in the Sanjiangyuan region. We used the MaxEnt model to determine the relation of their presence to environmental variables (e.g., elevation, ruggedness) and to predict snow leopard distribution. Model results showed 89,602 km(2) of snow leopard habitat in the Sanjiangyuan region, of which 7674 km(2) lay within Sanjiangyuan Nature Reserve's core zones. We analyzed the spatial relation between snow leopard habitat and Buddhist monasteries and found that 46% of monasteries were located in snow leopard habitat and 90% were within 5 km of snow leopard habitat. The 336 monasteries in the Sanjiangyuan region could protect more snow leopard habitat (8342 km(2) ) through social norms and active patrols than the nature reserve's core zones. We conducted 144 household interviews to identify local herders' attitudes and behavior toward snow leopards and other wildlife. Most local herders claimed that they did not kill wildlife, and 42% said they did not kill wildlife because it was a sin in Buddhism. Our results indicate monasteries play an important role in snow leopard conservation. Monastery-based snow leopard conservation could be extended to other Tibetan Buddhist regions that in total would encompass about 80% of the global range of snow leopards. © 2013 Society for Conservation Biology.

Trees in Urban and City Environments: a review of the selection criteria with particular reference to nature conservation in New Zealand Cities

2008-07-01

Full Text Available The overall aim of this research was to review the general criteria for selection of trees for urban environments and city environments. The reason for this research was to assess the extent to which criteria for tree selection can contribute to nature conservation in cities. We conducted an extensive review of the literature, looking for publications about the selection criteria. In particular, we looked for any previous published reviews of the criteria. With reference to the criteria used in New Zealand, we undertook an unstructured review of the practices adopted in most cities. A review of the literature revealed many publications about different criteria but only one publication in which there was a general review of the criteria used for selecting trees for urban environments. By way of contrast, lists of tree species deemed to be suitable (or unsuitable for urban planting are widely available, and some include information about selection criteria, but often with little background explanation. Worldwide, commonly used criteria included commercial availability of species, compatibility with urban environments, landscape design, low maintenance, avoidance of nuisance factors and historical practice. The most common criteria are concerned with the concept of choosing species compatible with local climate and soils. Anecdotal evidence suggests that more and more cities are using a mix of criteria including those that may contribute to conservation and restoration of native biota. We suggest that there should be greater use of ecological, genetic and biogeographical criteria to meet the needs of nature conservation in New Zealand cities.

Water pollution is known to play an important role in the pathogenesis of plastron, carapace and skin diseases of turtles. In this study, a total of 150 European pond turtles (Emys orbicularis) of different age and both sexes, originating from natural habitats in Serbia, were examined for morphological changes of the skin, plastron, carapace and skeletal system. The turtles were taken out from their natural habitats in Lake Ludas, Lake Palic and Lake Tresetiste. After artificial hibernation, they were subjected to detailed examination, sampled and treated, and finally returned into their natural habitat. Biopsies from the skin and shell were subjected to histopathological examination and microbiological analysis. X-ray scanning was also performed to detect changes in the skeletal system. Macroscopic changes of the skin, most frequently degenerative, inflammatory or neoplastic diseases, were diagnosed in 49.33% of the turtles examined. Dermatitis of different origin and form was the most prominent histopathological finding (28.00%). In the plastron, inflammatory and degenerative processes were frequently found. Osteopathy and mechanical injuries were the dominant findings. Macroscopic changes of the plastron, carapace and skeletal system were diagnosed in 67.33% of the turtles examined. Using X-ray scanning, generalised osteopathy, anomalies and malformations of different aetiology were also diagnosed on the tail and legs. Microbiological examinations showed the presence of a variety of bacterial and fungal agents, either primary pathogens or potential polluters, which invaded the skin and shell, or were present in cloacal swab samples. Bacterial infection was diagnosed in 76.66% of the turtles, first of all in those with skin and shell necrosis. Mycoses were diagnosed in 33.33% of the animals.

The European Crisis Management: An Organizational Narrative

Full Text Available The debate of scholars in the field of international relations in last years has put the European Union’s role into the consideration. The European Foreign and Security Policy has positioned itself through its development to the constructive and normative line of research of world politics. With this respect, this article examines a character of crisis management of the European Common Foreign Policy based on the institutional development. Besides the European Union does not possess a unified foreign and security policy, regardless one army and single institutional mechanism, the recent crisis management actions have shaped the policies into a comprehensive nature. The paper overviews briefly the history of Common Foreign and Security Policy as well as Common Security and Defence Policy and focuses on crisis management of civilian and military missions. The author claims that the development has a significant impact on a character of crisis management analyzed from the institutional and financial capacities of the European Security and Defence Policy. Consequently, the character of crisis management performs complex mechanisms of responsive, political/administrative, legal, economic and human help to crisis-affected territories in the world. Respectfully, the character of crisis management has thus more pre-crisis nature of a resilience.

Successful conservation efforts require understanding human behaviors that directly affect biodiversity. Choice of household location represents an observable behavior that has direct effects on biodiversity conservation, but no one has examined the sociocultural predictors of this choice relative to its environmental impacts. We conducted a case study of the Teton Valley of Idaho and Wyoming (U.S.A.) that (1) explored relationships between sociodemographic variables, environmental attitudes, and the environmental impact of household location choices, (2) assessed the potential for small household sizes in natural areas to multiply the environmental impacts of household location decisions, and (3) evaluated how length of residency predicted the environmental attitudes of people living in natural areas. We collected sociodemographic data, spatial coordinates, and land-cover information in a survey of 416 households drawn from a random sample of Teton Valley residents (95% compliance rate). Immigrants (respondents not born in the study area) with the lowest education levels and least environmentally oriented attitudes lived in previously established residential areas in disproportionately high numbers, and older and more educated immigrants with the most environmentally oriented attitudes lived in natural areas in disproportionately high numbers. Income was not a significant predictor of household location decisions. Those living in natural areas had more environmental impact per person because of the location and because small households (educated, and potentially growing more environmentally oriented, these patterns are troubling for biodiversity conservation. Our results demonstrate a need for environmentalists to make household location decisions that reflect their environmental attitudes and future research to address how interactions between education level, environmental attitudes, population aging, and household location choices influence biodiversity

Wild fire vulnerability is a measure of potential socio-economic damage caused by a fire in a specific area. As such it is an important component of long-term fire risk management, helping policy-makers take informed decisions about adequate expenditures for fire prevention and suppression, and to target those regions at highest risk. This paper presents a first approach to assess wild fire vulnerability at the European level. A conservative approach was chosen that assesses the cost of restoring the previous land cover after a potential fire. Based on the CORINE Land Cover, a restoration cost was established for each land cover class at country level, and an average restoration time was assigned according to the recovery capacity of the land cover. The damage caused by fire was then assessed by discounting the cost of restoring the previous land cover over the restoration period. Three different vulnerability scenarios were considered assuming low, medium and high fire severity causing different levels of damage. Over Europe, the potential damage of wild land fires ranges from 10 - 13, 732 Euro*ha-1*yr-1 for low fire severity, 32 - 45,772 Euro*ha-1*yr-1 for medium fire severity and 54 - 77,812 Euro*ha-1*yr-1 for high fire severity. The least vulnerable are natural grasslands, moors and heathland and sclerophyllous vegetation, while the highest cost occurs for restoring broad-leaved forest. Preliminary validation comparing these estimates with official damage assessments for past fires shows reasonable results. The restoration cost approach allows for a straightforward, data extensive assessment of fire vulnerability at European level. A disadvantage is the inherent simplification of the evaluation procedure with the underestimation of non-markets goods and services. Thus, a second approach has been developed, valuing individual wild land goods and services and assessing their annual flow which is lost for a certain period of time in case of a fire event.

Sixty-four percent of the 56 raptor and owl species that occur in Europe have an unfavorable conservation status. As well as requiring conservation measures in their own right, raptors and owls function as useful sentinels of wider environmental "health," because they are widespread top predators, relatively easy to monitor, and sensitive to environmental changes at a range of geographical scales. At a time of global acknowledgment of an increasing speed of biodiversity loss, and new, forward-looking and related European Union biodiversity policy, there is an urgent need to improve coordination at a pan-European scale of national initiatives that seek to monitor raptor populations. Here we describe current initiatives that make a contribution to this aim, particularly the current "MEROS" program, the results of a questionnaire survey on the current state of national raptor monitoring across 22 BirdLife Partners in Europe, the challenges faced by any enhanced pan-European monitoring scheme for raptors, and some suggested pathways for efficiently tapping expertise to contribute to such an initiative.

Conservationists need methods to conserve biological diversity while allowing species and communities to rearrange in response to a changing climate. We developed and tested such a method for northeastern North America that we based on physical features associated with ecological diversity and site resilience to climate change. We comprehensively mapped 30 distinct geophysical settings based on geology and elevation. Within each geophysical setting, we identified sites that were both connected by natural cover and that had relatively more microclimates indicated by diverse topography and elevation gradients. We did this by scoring every 405 ha hexagon in the region for these two characteristics and selecting those that scored >SD 0.5 above the mean combined score for each setting. We hypothesized that these high-scoring sites had the greatest resilience to climate change, and we compared them with sites selected by The Nature Conservancy for their high-quality rare species populations and natural community occurrences. High-scoring sites captured significantly more of the biodiversity sites than expected by chance (p < 0.0001): 75% of the 414 target species, 49% of the 4592 target species locations, and 53% of the 2170 target community locations. Calcareous bedrock, coarse sand, and fine silt settings scored markedly lower for estimated resilience and had low levels of permanent land protection (average 7%). Because our method identifies-for every geophysical setting-sites that are the most likely to retain species and functions longer under a changing climate, it reveals natural strongholds for future conservation that would also capture substantial existing biodiversity and correct the bias in current secured lands. © 2014 The Authors.
