description Publicationkeyboard_double_arrow_right Article 2019 BelgiumPublisher:Elsevier BV Authors: Frédéric Dobruszkes;Frédéric Dobruszkes;Scholars and experts in air transport generally assume the distance flown between airports is the shortest route (also known as the great-circle distance or the orthodromic route). Howev-er, in the real world, planes follow longer itineraries. This paper reviews the factors of de-tours, based on interviews with pilots and experts in air navigation. Factors relate to (1) technical constraints, (2) natural processes (including meteorological conditions) and obsta-cles, (3) geopolitical factors and (4) social factors, which are all explored in this paper. Their temporary vs. permanent and spatial impact (small vs. long detours) varies signifi-cantly among factors and among cases, as well as their avoidable nature. Appropriate poli-cies could lower detours. In addition, these results echo academic debates on the meaning of distance. info:eu-repo/semantics/published

Norilsk is one of the most polluted cities in the world, largely because of intense mining of heavy metals. Here we present satellite observations of SO2 in a large area surrounding the city, derived from 4 years of measurements from the Infrared Atmospheric Sounding Interferometer (IASI), the nadir thermal infrared (TIR) sounder onboard the MetOp platforms. TIR instruments are conventionally considered to be inadequate for monitoring near-surface composition, because their sensitivity to the lowest part of the atmosphere is limited by the thermal contrast between the ground and the air above it. We demonstrate that IASI is capable of measuring SO2 (here as a partial column from 0 to 2 km) in Norilsk, thanks to the large temperature inversions and the low humidity in wintertime. We discuss the influence of thermal contrast and of surface humidity on the SO2 retrieved columns and estimate the retrieval errors. Using a simple box model, we derive the yearly total emissions of SO2 from Norilsk and compare them to previously reported values. More generally, we present in this work the first large-scale demonstration of the capability of space-based TIR sounders to measure near-surface SO2 anthropogenic pollution. info:eu-repo/semantics/published SCOPUS: ar.j

This study reviews the current status of the five main commercial Entandrophragma species: Entandrophragma angolense, E. congo-lense (often confused with E. angolense), E. candollei, E. cylindricum and E. utile. We suggest directions for research to improve sustainable management strategies for this genus. The study draws mainly on published scientific data, economic data (production and export sta-tistics) and on relevant laws and regulations, but also on existing management plans and inventory reports. Although these species are reported as vulnerable on the IUCN Red List, knowledge on their management is still patchy. Industrial and artisanal logging is intensive and does not always follow a validated management plan or abide by the minimum rotation period, both of which would help to ensure the renewal of these resources. Managing them to ensure that logging is sustainable in the long term requires management measures to be developed and complied with. Sustainable use has to be based on appropriate management of natural stands and on reforestation and conservation measures. Research studies to be developed should encompass the growth rates of the species in the light of the changing climate, assessments of stocks (timber, biomass and carbon), updates of their spatial distribution, improvements to natural regeneration, reproduction processes and the anatomical and technical properties of each species. All these research topics are necessary to ensure the permanence of these Entandrophragma species. info:eu-repo/semantics/published SCOPUS: ar.j

In this work, we derive the global distributions of these two organic species using for the first time the Infrared Atmospheric Sounding Interferometer (IASI) launched onboard the MetOp-A satellite in 2006. This paper describes the method used and provides a first critical analysis of the retrieved products. The retrieval process follows a two-step approach in which global distributions are first obtained on the basis of a simple radiance indexing (transformed into brightness temperatures), and then mapped onto column abundances using suitable conversion factors. For methanol, the factors were calculated using a complete retrieval approach in selected regions. In the case of formic acid, a different approach, which uses a set of forward simulations for representative atmospheres, has been used. In both cases, the main error sources are carefully determined: the average relative error on the column for both species is estimated to be about 50%, increasing to about 100% for the least favorable conditions. The distributions for the year 2009 are discussed in terms of seasonality and source identification. Time series comparing methanol, formic acid and carbon monoxide in different regions are also presented. info:eu-repo/semantics/published SCOPUS: ar.j

In vegetation science and forest management, tree density is often used as a variable. To determine the value of this variable, reliable field methods are necessary. When vegetation is sparse or not easily accessible, the use of sample plots is not feasible in the field. Therefore, plotless methods, like the Point Centred Quarter Method, are often used as an alternative. In this study we investigate the accuracy of different plotless sampling methods. To this end, tree densities of a mangrove forest were determined and compared with estimates provided by several plotless methods. None of these methods proved accurate across all field sites with mean underestimations up to 97% and mean overestimations up to 53% in the field. Applying the methods to different vegetation patterns shows that when random spatial distributions were used the true density was included within the 95% confidence limits of all the plotless methods tested. It was also found that, besides aggregation and regularity, density trends often found in mangroves contribute to the unreliability. This outcome raises questions about the use of plotless sampling in forest monitoring and management, as well as for estimates of density-based carbon sequestration. We give recommendations to minimize errors in vegetation surveys and recommendations for further in-depth research. info:eu-repo/semantics/published JOURNAL ARTICLE SCOPUS: ar.j

Phase one consists of pest categorisation to determine whether the pest has the characteristics of a quarantine pest or those of a regulated non‐quarantine pest for the area of the EU. Phase two consists of pest risk assessment, which may be requested by the risk managers following the pest categorisation results. This Guidance provides a template for pest categorisation and describes in detail the use of modelling and expert knowledge elicitation to conduct a pest risk assessment. The Guidance provides support and a framework for assessors to provide quantitative estimates, together with associated uncertainties, regarding the entry, establishment, spread and impact of plant pests in the EU. The Guidance allows the effectiveness of risk reducing options (RROs) to be quantitatively assessed as an integral part of the assessment framework. A list of RROs is provided. A two‐tiered approach is proposed for the use of expert knowledge elicitation and modelling. Depending on data and resources available and the needs of risk managers, pest entry, establishment, spread and impact steps may be assessed directly, using weight of evidence and quantitative expert judgement (first tier), or they may be elaborated in substeps using quantitative models (second tier). An example of an application of the first tier approach is provided. Guidance is provided on how to derive models of appropriate complexity to conduct a second tier assessment. Each assessment is operationalised using Monte Carlo simulations that can compare scenarios for relevant factors, e.g. with or without RROs. This document provides guidance on how to compare scenarios to draw conclusions on the magnitude of pest risks and the effectiveness of RROs and on how to communicate assessment results.

The present study serves to review this literature and highlight the causes of such apparently large species numbers, while providing an objective and realistic review of the mangrove species actually present in Sri Lanka today. This study is based on standardized fieldwork over a 4-year period using wellestablished diagnostic identification keys. The study indicates that there are at present 20 identified ‘mangrove species’ (major and minor components) and at least 18 ‘mangrove associates’ along the south-western coast of the island, and addresses the importance of clearly defining these terms. Incorrect identifications in the past have adversely affected interpretation of species composition in the framework of biogeography, remote sensing and biological conservation and management. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society, 138, 29‐43.

Khan;Philip Stessens; Frank Canters; Marijke Huysmans; Ahmed Z. Khan;For city dwellers urban green space is the primary source of contact with nature. Qualitative green space is increasingly perceived as an important factor for quality of life in urban areas and a key component of sustainable urban design and planning. In this study, the relation between different features of urban green spaces and perception of green space qualities was analyzed by combining the outcome of a survey on green space perception with GIS-based spatial metrics. A survey has been conducted among residents of the Brussels Capital Region and surroundings to assess the relative importance residents assign to different qualities of urban green spaces and how they value these qualities within visited spaces. Quietness, spaciousness, cleanliness and maintenance, facilities and feeling of safety are identified as important qualities of public green spaces, while naturalness, historical and cultural value are perceived as less important qualities. A GIS-based model was developed to infer naturalness, quietness and spaciousness as perceived by users of public green spaces from green space properties. Using variables describing biological value, land-cover composition, green space area and shape, good correlations were obtained between GIS-based assessment of naturalness and spaciousness and how green space users perceive these qualities. The model proposed may be useful for simulating green space development and improvement scenarios and assess their impact on perceived quality. Thus it may serve as a spatial decision support tool for improving the quality of urban green spaces. info:eu-repo/semantics/published SCOPUS: ar.j

We explored these aspects through a study based on semi-structured interviews with 88 traditional therapists from the Batwa, Havu, Shi and Tembo communities near the montane forests of the Kahuzi-Biega National Park, in South Kivu Province in eastern DRC. Our survey showed that 77 plant species are used to treat pathologies grouped into 18 categories of ailments, the most frequent being digestive disorders and infections. Leaves and bark are the parts most frequently used, usually in recipes involving a single plant and mainly prepared as aqueous solutions. Although there is a positive correlation between the accessibility of plants and the frequency of their use (H = 17.64; p < 0.001), some less accessible forest plants have very high use frequencies. Consensus between traditional therapists is high overall, especially for musculo-skeletal disorders (= 0.83) and infections (= 0.80). Although the degree of fidelity to a plant for a given category of ailments is low overall, it is always high for at least one plant in all categories. Our results, although exploratory, suggest that certain medicinal traditions are well rooted in the region's local communities. This assumes a good local knowledge of medicinal plants, intergenerational transmission of that knowledge and a degree of cooperation between traditional therapists. Further studies are needed to assess these different aspects with greater precision. info:eu-repo/semantics/published SCOPUS: ar.j

Leclair de Bellevue; Christelle Barthe; Françoise Posny; Philippe Ricaud; Abdel Abchiche; Robert Delmas;Since the nineties, atmospheric measurement systems have been deployed at Reunion Island, mainly for monitoring the atmospheric composition in the framework of NDSC/NDACC (Network for the Detection of Stratospheric Change/Network for the Detection of Atmospheric Composition Change). The location of Reunion Island presents a great interest because there are very few multi-instrumented stations in the tropics and particularly in the southern hemisphere. In 2012, a new observatory was commissioned in Maïdo at 2200 m above sea level: it hosts various instruments for atmospheric measurements, including lidar systems, spectro-radiometers and in situ gas and aerosol measurements. This new high-altitude Maïdo station provides an opportunity: 1. to improve the performance of the optical instruments above the marine boundary layer, and to open new perspectives on upper troposphere and lower stratosphere studies; 2. to develop in situ measurements of the atmospheric composition for climate change surveys, in a reference site in the tropical/subtropical region of the southern hemisphere; 3. to offer trans-national access to host experiments or measurement campaigns for focused process studies. © 2013 Author(s). info:eu-repo/semantics/published SCOPUS: ar.j

description Publicationkeyboard_double_arrow_right Article 2019 BelgiumPublisher:Elsevier BV Authors: Frédéric Dobruszkes;Frédéric Dobruszkes;Scholars and experts in air transport generally assume the distance flown between airports is the shortest route (also known as the great-circle distance or the orthodromic route). Howev-er, in the real world, planes follow longer itineraries. This paper reviews the factors of de-tours, based on interviews with pilots and experts in air navigation. Factors relate to (1) technical constraints, (2) natural processes (including meteorological conditions) and obsta-cles, (3) geopolitical factors and (4) social factors, which are all explored in this paper. Their temporary vs. permanent and spatial impact (small vs. long detours) varies signifi-cantly among factors and among cases, as well as their avoidable nature. Appropriate poli-cies could lower detours. In addition, these results echo academic debates on the meaning of distance. info:eu-repo/semantics/published

Norilsk is one of the most polluted cities in the world, largely because of intense mining of heavy metals. Here we present satellite observations of SO2 in a large area surrounding the city, derived from 4 years of measurements from the Infrared Atmospheric Sounding Interferometer (IASI), the nadir thermal infrared (TIR) sounder onboard the MetOp platforms. TIR instruments are conventionally considered to be inadequate for monitoring near-surface composition, because their sensitivity to the lowest part of the atmosphere is limited by the thermal contrast between the ground and the air above it. We demonstrate that IASI is capable of measuring SO2 (here as a partial column from 0 to 2 km) in Norilsk, thanks to the large temperature inversions and the low humidity in wintertime. We discuss the influence of thermal contrast and of surface humidity on the SO2 retrieved columns and estimate the retrieval errors. Using a simple box model, we derive the yearly total emissions of SO2 from Norilsk and compare them to previously reported values. More generally, we present in this work the first large-scale demonstration of the capability of space-based TIR sounders to measure near-surface SO2 anthropogenic pollution. info:eu-repo/semantics/published SCOPUS: ar.j

This study reviews the current status of the five main commercial Entandrophragma species: Entandrophragma angolense, E. congo-lense (often confused with E. angolense), E. candollei, E. cylindricum and E. utile. We suggest directions for research to improve sustainable management strategies for this genus. The study draws mainly on published scientific data, economic data (production and export sta-tistics) and on relevant laws and regulations, but also on existing management plans and inventory reports. Although these species are reported as vulnerable on the IUCN Red List, knowledge on their management is still patchy. Industrial and artisanal logging is intensive and does not always follow a validated management plan or abide by the minimum rotation period, both of which would help to ensure the renewal of these resources. Managing them to ensure that logging is sustainable in the long term requires management measures to be developed and complied with. Sustainable use has to be based on appropriate management of natural stands and on reforestation and conservation measures. Research studies to be developed should encompass the growth rates of the species in the light of the changing climate, assessments of stocks (timber, biomass and carbon), updates of their spatial distribution, improvements to natural regeneration, reproduction processes and the anatomical and technical properties of each species. All these research topics are necessary to ensure the permanence of these Entandrophragma species. info:eu-repo/semantics/published SCOPUS: ar.j

In this work, we derive the global distributions of these two organic species using for the first time the Infrared Atmospheric Sounding Interferometer (IASI) launched onboard the MetOp-A satellite in 2006. This paper describes the method used and provides a first critical analysis of the retrieved products. The retrieval process follows a two-step approach in which global distributions are first obtained on the basis of a simple radiance indexing (transformed into brightness temperatures), and then mapped onto column abundances using suitable conversion factors. For methanol, the factors were calculated using a complete retrieval approach in selected regions. In the case of formic acid, a different approach, which uses a set of forward simulations for representative atmospheres, has been used. In both cases, the main error sources are carefully determined: the average relative error on the column for both species is estimated to be about 50%, increasing to about 100% for the least favorable conditions. The distributions for the year 2009 are discussed in terms of seasonality and source identification. Time series comparing methanol, formic acid and carbon monoxide in different regions are also presented. info:eu-repo/semantics/published SCOPUS: ar.j

In vegetation science and forest management, tree density is often used as a variable. To determine the value of this variable, reliable field methods are necessary. When vegetation is sparse or not easily accessible, the use of sample plots is not feasible in the field. Therefore, plotless methods, like the Point Centred Quarter Method, are often used as an alternative. In this study we investigate the accuracy of different plotless sampling methods. To this end, tree densities of a mangrove forest were determined and compared with estimates provided by several plotless methods. None of these methods proved accurate across all field sites with mean underestimations up to 97% and mean overestimations up to 53% in the field. Applying the methods to different vegetation patterns shows that when random spatial distributions were used the true density was included within the 95% confidence limits of all the plotless methods tested. It was also found that, besides aggregation and regularity, density trends often found in mangroves contribute to the unreliability. This outcome raises questions about the use of plotless sampling in forest monitoring and management, as well as for estimates of density-based carbon sequestration. We give recommendations to minimize errors in vegetation surveys and recommendations for further in-depth research. info:eu-repo/semantics/published JOURNAL ARTICLE SCOPUS: ar.j

Phase one consists of pest categorisation to determine whether the pest has the characteristics of a quarantine pest or those of a regulated non‐quarantine pest for the area of the EU. Phase two consists of pest risk assessment, which may be requested by the risk managers following the pest categorisation results. This Guidance provides a template for pest categorisation and describes in detail the use of modelling and expert knowledge elicitation to conduct a pest risk assessment. The Guidance provides support and a framework for assessors to provide quantitative estimates, together with associated uncertainties, regarding the entry, establishment, spread and impact of plant pests in the EU. The Guidance allows the effectiveness of risk reducing options (RROs) to be quantitatively assessed as an integral part of the assessment framework. A list of RROs is provided. A two‐tiered approach is proposed for the use of expert knowledge elicitation and modelling. Depending on data and resources available and the needs of risk managers, pest entry, establishment, spread and impact steps may be assessed directly, using weight of evidence and quantitative expert judgement (first tier), or they may be elaborated in substeps using quantitative models (second tier). An example of an application of the first tier approach is provided. Guidance is provided on how to derive models of appropriate complexity to conduct a second tier assessment. Each assessment is operationalised using Monte Carlo simulations that can compare scenarios for relevant factors, e.g. with or without RROs. This document provides guidance on how to compare scenarios to draw conclusions on the magnitude of pest risks and the effectiveness of RROs and on how to communicate assessment results.

The present study serves to review this literature and highlight the causes of such apparently large species numbers, while providing an objective and realistic review of the mangrove species actually present in Sri Lanka today. This study is based on standardized fieldwork over a 4-year period using wellestablished diagnostic identification keys. The study indicates that there are at present 20 identified ‘mangrove species’ (major and minor components) and at least 18 ‘mangrove associates’ along the south-western coast of the island, and addresses the importance of clearly defining these terms. Incorrect identifications in the past have adversely affected interpretation of species composition in the framework of biogeography, remote sensing and biological conservation and management. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society, 138, 29‐43.

Khan;Philip Stessens; Frank Canters; Marijke Huysmans; Ahmed Z. Khan;For city dwellers urban green space is the primary source of contact with nature. Qualitative green space is increasingly perceived as an important factor for quality of life in urban areas and a key component of sustainable urban design and planning. In this study, the relation between different features of urban green spaces and perception of green space qualities was analyzed by combining the outcome of a survey on green space perception with GIS-based spatial metrics. A survey has been conducted among residents of the Brussels Capital Region and surroundings to assess the relative importance residents assign to different qualities of urban green spaces and how they value these qualities within visited spaces. Quietness, spaciousness, cleanliness and maintenance, facilities and feeling of safety are identified as important qualities of public green spaces, while naturalness, historical and cultural value are perceived as less important qualities. A GIS-based model was developed to infer naturalness, quietness and spaciousness as perceived by users of public green spaces from green space properties. Using variables describing biological value, land-cover composition, green space area and shape, good correlations were obtained between GIS-based assessment of naturalness and spaciousness and how green space users perceive these qualities. The model proposed may be useful for simulating green space development and improvement scenarios and assess their impact on perceived quality. Thus it may serve as a spatial decision support tool for improving the quality of urban green spaces. info:eu-repo/semantics/published SCOPUS: ar.j

We explored these aspects through a study based on semi-structured interviews with 88 traditional therapists from the Batwa, Havu, Shi and Tembo communities near the montane forests of the Kahuzi-Biega National Park, in South Kivu Province in eastern DRC. Our survey showed that 77 plant species are used to treat pathologies grouped into 18 categories of ailments, the most frequent being digestive disorders and infections. Leaves and bark are the parts most frequently used, usually in recipes involving a single plant and mainly prepared as aqueous solutions. Although there is a positive correlation between the accessibility of plants and the frequency of their use (H = 17.64; p < 0.001), some less accessible forest plants have very high use frequencies. Consensus between traditional therapists is high overall, especially for musculo-skeletal disorders (= 0.83) and infections (= 0.80). Although the degree of fidelity to a plant for a given category of ailments is low overall, it is always high for at least one plant in all categories. Our results, although exploratory, suggest that certain medicinal traditions are well rooted in the region's local communities. This assumes a good local knowledge of medicinal plants, intergenerational transmission of that knowledge and a degree of cooperation between traditional therapists. Further studies are needed to assess these different aspects with greater precision. info:eu-repo/semantics/published SCOPUS: ar.j

Leclair de Bellevue; Christelle Barthe; Françoise Posny; Philippe Ricaud; Abdel Abchiche; Robert Delmas;Since the nineties, atmospheric measurement systems have been deployed at Reunion Island, mainly for monitoring the atmospheric composition in the framework of NDSC/NDACC (Network for the Detection of Stratospheric Change/Network for the Detection of Atmospheric Composition Change). The location of Reunion Island presents a great interest because there are very few multi-instrumented stations in the tropics and particularly in the southern hemisphere. In 2012, a new observatory was commissioned in Maïdo at 2200 m above sea level: it hosts various instruments for atmospheric measurements, including lidar systems, spectro-radiometers and in situ gas and aerosol measurements. This new high-altitude Maïdo station provides an opportunity: 1. to improve the performance of the optical instruments above the marine boundary layer, and to open new perspectives on upper troposphere and lower stratosphere studies; 2. to develop in situ measurements of the atmospheric composition for climate change surveys, in a reference site in the tropical/subtropical region of the southern hemisphere; 3. to offer trans-national access to host experiments or measurement campaigns for focused process studies. © 2013 Author(s). info:eu-repo/semantics/published SCOPUS: ar.j
