Reserve networks are a major tool of ecological management aiming at biodiversity conservation. Maximizing the number of species conserved with the minimum land sacrifice is a primary requirement in reserve design. In this study, we examine the efficiency of five different scenarios to conserve: (i) the biodiversity of one target group and (ii) the overall biodiversity of an area. The study was conducted in Dadia Reserve, in northern Greece. Six groups of species were selected to represent its biodiversity: woody plants, orchids, Orthoptera, aquatic and terrestrial herpetofauna, and small terrestrial birds. The scenarios examined represent different conservation approaches to select network sites. For each approach, the starting point was one of the above six groups of species, considered as the target group. In scenario A, which reflects the hotspot approach, the sites richest in species are selected. Scenario B selects the sites most complementary in terms of species richness. The next two scenarios use the principle of environmental representativeness, expressed in terms of habitat (scenario C) or vegetation (scenario D). Under scenario E, sites forming the network are selected at random. The rank of scenarios in terms of preserving the species of the target group was always B>A>C>D>E, irrespective of the group considered as target group. Their rank, when preservation of the total biodiversity was the issue, was B, A>C, D>E. © 2004 Elsevier Ltd. All rights reserved. [less ▲]

Wildlife meat is an important source of animal protein for rural and urban populations in Congo. Quantitative and qualitative surveys on the consumption of bushmeat were undertaken in Brazzaville in 2006, in about 1,050 urban households. The main objective was to establish the profiles of consumers and of species concerned. The results showed that 88.3% of the surveyed households consumed bushmeat. Their average size was 5.7 ± 3.2 persons. The average monthly income of an urban consumer with a permanent job was 98,334 (US$197) ± 84,306 (US$169) FCFA. It appeared that households preferred to consume bushmeat for two major reasons: the taste or flavor (67.8%) and food habits (14.7%). Meat from mammals was preferred, the top three orders of this class being artiodactyls (48.3%), rodents (28.3%), and primates (13.0%). Some of them are listed as threatened in Congo Brazzaville and are included in the IUCN Red List. The results showed that in Brazzaville, bushmeat consumption remains important and is determined by socio-economic parameters. The promotion of game farming, and breeding of domestic species such as poultry and fish, in the Brazzaville suburbs could help to meet Congolese demand for bushmeat. [less ▲]

Endowed with 3,260 km of coastal line and 112 estuaries, Vietnam has a high potential for aquaculture development. However, long coastal line is also embedded with natural high risks under climate changes and sea level rise. Vietnam is ranked at the 18th in the 2015 world risk index and the vulnerability index of 50.9%. Relying on coastal resources, aquatic farmers have adopted a number of strategies to cope with aquaculture risks. By using the OECD holistic approach, this research used several tools to identify farmer's performance on clam farming practices and their risk management strategies (RMS) in Thaibinh province (the largest area of the clam production in the north and north central coastal part of Vietnam). RSMs are found of diversification and flexibility among farmers. For production risks, the RSMs are: (1) enlarging clam raising size and (2) actively controlling clam production by experience and technical innovations. For market risks, the RSM is searching for more clam market channels in both input and output market. For financial risks, RSMs are (1) securing family from clam farming loss by diversifying livelihood activities and (2) accessing secure financial sources in term or interest and bond conditions. Although some RSMs had resulted positive impacts but in overall, the clam farming risks have not managed well by those strategies due to the limitation in capacity of households comparing with level of risks. To cope better with different risks in clam sector, besides the adjustment in RSMs of farmers themselves, it is necessary to have the intervention from government (from national to local level) to address the aquaculture risks which the farmers cannot handle by themselves, such as (1) addressing the issue of polluted wastewater to the clam field; and (2) more focusing in supporting farmer in linkages to the both formal financial market and output market. In addition, supports for technical training targeting on improving farmer's skills and knowledge in farming decision making and market information is also of high value to clam farmers in coping with farming risks.

Quantitative studies are commonly realised in the biomedical research to compare RNA expression in different experimental or clinical conditions. These quantifications are performed through their comparison to the expression of the housekeeping gene transcripts like glyceraldehyde-3-phosphate dehydrogenase (G3PDH), albumin, actins, tubulins, cyclophilin, hypoxantine phsophoribosyltransferase (HRPT), L32. 28S, and 18S rRNAs are also used as internal standards. In this paper, it is recalled that the commonly used internal standards can quantitatively vary in response to various factors. Possible variations are illustrated using three experimental examples. Preferred types of internal standards are then proposed for each of these samples and thereafter the general procedure concerning the choice of an internal standard and the way to manage its uses are discussed.

First in the USA and then in many other countries, scholarship on environmental inequality has sought to shed light on the unequal environmental conditions borne by poor people and ethnic minorities, and to challenge public policies and their unjust impacts on those target groups. Housing quality, especially the indoor characteristics of homes, offers an innovative perspective in this field of research. In previous research on environmental inequality in the Walloon context, housing quality has been proven to be a major determinant of quality of life and environmental well-being. This paper analyses housing quality through a twofold approach: through indoor characteristics on the one hand, and outdoor subjective and objective externalities on the other. It reveals the disparities between the most deprived and the wealthiest segments of the population. The evidence for this study is based on a housing quality survey carried out in 2012 and 2013 on 6,018 households in Wallonia (Belgium). The key findings are that poor people are found to live in housing of lower quality, in densely populated neighbourhoods and those with mixed use, with compensating amenities provided at the local level. Moreover, consistent with environmental inequality scholarship, deprived households are found to bear the burden of environmental degradation outside the home. People live in areas with poorer air quality, but are found to benefit from greater access to green spaces. The results of the survey reveal an interesting point concerning the environmental inequality literature; the interior features of housing are found to differ more widely between deprived and wealthier people than the surrounding environment does.

Algorithmic and computer programming in the bachelor’s degree is a course that demands a large involvement of students in performing non-standard exercises. This practical aspect is incompatible with classical ex cathedra course. It is the reason why we implement a blended learning approach much more responsive to students in a bachelor class of Bio Engineering at the Gembloux Agro Bio Tech Faculty (University of Liege, Belgium). This course alternates theoretical classes, take-home lessons with the help of online pedagogical resources and video and debriefing sessions where students have the possibility to benefit from teacher’ support. In doing so, the students are better prepared for the examination. They also gain in confidence and motivation. The teacher no longer simply transmits the knowledge but assists the students in their reflection process and their mastering of programming tools [less ▲]

Monetary valuation of ecosystem services (ES) is gaining growing interest in scientific papers, policies and awareness-raising documents for its potential as a communication tool illustrating the societal importance of biodiversity. However, simultaneously, its limitations are increasingly discussed in the literature. In this paper we argue that monetary valuation of ES should be seen as representing only one component of ES valuations. We provide basic standards to ensure integrated approaches to ES valuation that can effectively contribute to preserving cultural and biological diversity by acknowledging boundaries to resource exploitation and by building on the various interests and socio-cultural values of involved stakeholders. We base our discussion on a recent study that assesses the economic value of the world-famous Virunga National Park in the Democratic Republic of Congo, home to some of the last mountain gorillas (Gorilla beringei beringei). We alert against some ES monetary valuation that narrowly frames biodiversity conservation in terms of economic calculus and argue that subjugating conservation efforts to profit logics downplays the importance of intrinsic, symbolic and other non-economic values of biodiversity. We conclude by providing principles and methodological guidelines to enhance ES valuation as a tool to promote awareness rising for biodiversity conservation through the understanding the overall importance of biodiversity for human societies.

Many studies showed the high frequency of cutaneous intolerances to ketoprofen but in 85 percent of them, these are photoallergies. The Belgian dematologists published an article a few years ago, demonstrating that it is important to avoid prescription of topical ketoprofen during sunny periods. Our experience showed the risks of lesions without exposing to UV radiations. These gels, on free sale, are widely used by the public. In physiotherapy, they are also regularly used by practitioners who rarely know the risk of photoallergies and often ignore the possibility of burn. In France, many questions have already been asked about these gels and they were even the object of a temporary withdrawal. [less ▲]

A sharp increase in extreme heat and drought stress is projected in Belgium by the end of the 21st century, with the potential to significantly reduce crops’ yields under current agricultural practices. This contribution uses an agro-hydrological model in order to assess the potential effects of climate evolution on crop development, yield, and water balance for the main agricultural productions in the Meuse catchment. Erosion risk is also evaluated. We show that grasslands and maize yield decrease and yield variability increases under climate change scenarios. The leaf area index study permits to put in emphasis the earlier start of the vegetation due to warmer climate. It appears that all the sensitive stages occur earlier in the season and that crops are negatively affected by summer drought stress. The better understanding of crops development under evolving climate allows us to propose some changes in agricultural practices and to assess their effectiveness. We evaluate different strategies of adaptation in agricultural practices in order to reduce the potential negative effects of climate change on grasslands and maize production. Adaptation strategies proposed are advanced sowing and harvesting date, introduction of a cover crop for maize and advance in the cutting dates for grasslands. In the particular case of the Vesdre catchment, shifting the growth period of maize permits to avoid the water-deficit period and allow increased yield. This shift makes it possible to introduce a cover crop that will drastically reduce winter soil erosion. For grassland, the adjustment of the cutting dates favored the first cut and the earlier start of the vegetation. The second cut is less profitable due to summer drought stress. The vulnerability assessments focused on the main rotation encountered in the cultivated areas and in the difference in the cover type of these crops. [less ▲]
