Citizen science has been gaining momentum in the United States and Europe, where citizens are literate and often interested in science. However, in developing countries, which have a dire need for environmental data, such programs are slow to emerge, despite the large and untapped human resources in close proximity to areas of high biodiversity and poorly known floras and faunas. Thus, we propose that the parataxonomist and paraecologist approach, which originates from citizen‐based science, is well suited to rural areas in developing countries. Being a paraecologist or a parataxonomist is a vocation and entails full‐time employment underpinned by extensive training, whereas citizen science involves the temporary engagement of volunteers. Both approaches have their merits depending on the context and objectives of the research. We examined 4 ongoing paraecologist or parataxonomist programs in Costa Rica, India, Papua New Guinea, and southern Africa and compared their origins, long‐term objectives, implementation strategies, activities, key challenges, achievements, and implications for resident communities. The programs supported ongoing research on biodiversity assessment, monitoring, and management, and participants engaged in non‐academic capacity development in these fields. The programs in Southern Africa related to specific projects, whereas the programs in Costa Rica, India, and Papua New Guinea were designed for the long term, provided sufficient funding was available. The main focus of the paraecologists’ and parataxonomists’ activities ranged from collection and processing of specimens (Costa Rica and Papua New Guinea) or of socioeconomic and natural science data (India and Southern Africa) to communication between scientists and residents (India and Southern Africa). As members of both the local land user and research communities, paraecologists and parataxonomists can greatly improve the flow of biodiversity information to all users, from local stakeholders to international academia. 相似文献
The European Union has defined an ambitious objective for the future concerning sustainable land use to stop the process of land take by 2050. But can this objective be reliably monitored? In this paper, which is based on the case study of Luxembourg and the neighbouring regions, we show that the tools that are used to monitor land-take produce different results that prevent from comparing the figures from one region to another. Moreover, a comparison of the strategic documents related to land use in this cross-border region shows that land-use policies are the product of very different contexts and relationships towards land as a resource, which need to be addressed with tailored strategies. 相似文献
In the event of an accidental atmospheric release of radionuclides from a nuclear power plant, accurate real-time forecasting of the activity concentrations of radionuclides is acutely required by the decision makers for the preparation of adequate countermeasures. Yet, the accuracy of the forecasted plume is highly dependent on the source term estimation. Inverse modelling and data assimilation techniques should help in that respect. However the plume can locally be thin and could avoid a significant part of the radiological monitoring network surrounding the plant. Deploying mobile measuring stations following the accident could help to improve the source term estimation. In this paper, a method is proposed for the sequential reconstruction of the plume, by coupling a sequential data assimilation algorithm based on inverse modelling with an observation targeting strategy. The targeting design strategy consists in seeking the optimal locations of the mobile monitors at time t + 1 based on all available observations up to time t.The performance of the sequential assimilation with and without targeting of observations has been assessed in a realistic framework. It focuses on the Bugey nuclear power plant (France) and its surroundings within 50 km from the plant. The existing surveillance network is used and realistic observational errors are assumed. The targeting scheme leads to a better estimation of the source term as well as the activity concentrations in the domain. The mobile stations tend to be deployed along plume contours, where activity concentration gradients are important. It is shown that the information carried by the targeted observations is very significant, as compared to the information content of fixed observations. A simple test on the impact of model error from meteorology shows that the targeting strategy is still very useful in a more uncertain context. 相似文献
The present study was aimed at investigating road users’ perceptions and behaviors in case of a fire in a tunnel. It is grounded on the idea that in order to effectively prevent accidents and fires in tunnels, it may be useful to take tunnel users’ beliefs, representations, and coping strategies into account [Kouabenan, D.R., 1998. Beliefs and the perception of risks and accidents. Risk Analysis, an International Journal 18, 243–252; Kouabenan, D.R., 2001. Management de la sécurité: rôle des croyances et des perceptions.

Methicillin-Resistant Staphylococcus Aureus Risk Perception by Healthcare Personnel in a Public Hospital. Social Behavior and Personality, 35, 1] One hundred and fifty-one road users (firemen, truck drivers, regular drivers, and driving-school students) filled out a questionnaire measuring their perceptions of risks and control in road tunnels, their awareness of safety and rescue devices, their level of anxiety, and their behavioral intentions in the event of a fire in a road tunnel. The results indicated a relationship between fire-risk perception, awareness of rescue and safety devices, and road-tunnel experience; a tendency toward comparative optimism (CO); an effect of perceived control on optimism; and a relationship between CO and awareness of safety devices. A significant interaction was found between tunnel users’ anxiety level and their perceived control over the situation. The evacuation behaviors and coping strategies reported by the participants were far from reflecting the expected behaviors. Recommendations for a long-term prevention policy bearing jointly on beliefs, behaviors, improved information and warning systems are suggested. 相似文献
Winter alpine tourism has been repeatedly identified as one of the economic sectors most at risk from climate change in Switzerland. However, all of the costs that have been estimated so far for the Swiss tourism sector are, to some extent, misleading as they do not, or only partially, incorporate adaptation possibilities and general equilibrium effects. We attempt to fill this gap using a computable general equilibrium model that is specifically designed for the purposes of this research. Our modeling efforts first consist in creating a tourism sector with a part of it being dependent on snow. We also carefully model the snowmaking technology. Using climate change scenarios on future snow cover, we analyze their impacts on the Swiss ski industry. We find welfare effects for the Swiss economy ranging from − 23 to 113 million CHF in 2050. This range arises from the use of various assumptions concerning adaptation possibilities. We also show that geographical substitutions between international ski destinations have large positive effects for Switzerland. From a more general perspective, our results exemplify the risks of estimating the consequences of climate change based only on domestic impacts of climate change with no adaptation being implemented.
