Contribution des Systèmes d’Information Géographique (SIG) à l’analyse de l’approvisionnement en Eau Potable dans la Commune de Kétou au Sud du Benin

Cette étude aborde le problème de l’approvisionnement en eau potable dans la Commune de Kétou au Sud du Bénin. L’objectif poursuivi était d’évaluer la distribution spatiale des ouvrages d’approvisionnement en eau potable et la satisfaction des populations de la Commune de Kétou par rapport à la demande en eau potable. La distribution spatiale, l’accessibilité et la surexploitation des ouvrages d’approvisionnement en eau potable fonctionnels ont été évalués grâce à la cartographie thématique et l’analyse spatiale. Les résultats obtenus indiquent que les infrastructures sont inégalement réparties sur le territoire de la Commune. L’arrondissement d’Adakplamè est le moins desservi en ouvrages hydrauliques tandis que l’arrondissement de Kpankou présente le plus grand nombre d’ouvrages. Plus de 30% des ouvrages disponibles sont en panne, ce qui crée une surexploitation des points d’eau fonctionnels. L’accessibilité aux différents ouvrages est acceptable seulement dans les arrondissements au Sud de la Commune. Les ouvrages fonctionnels sont surchargés par rapport aux normes de desserte en fonction du type d’ouvrage. Au vu de ces constats, il s’avèrenécessaire de prévoir la réalisation de nouveaux ouvrages et de procéder à la réparation de certaines infrastructures en panne afin de faire face aux demandes croissantes en eau potable dans la Commune.Mots clés : Distribution spatiale, ouvrages hydrauliques, inégale répartition, Kétou, département du plateau.   English Title: Contribution of GIS in the diagnosis of the drinking water supply system in the town of Kétou in south BeninThis study addresses the problem of drinking water supply in the Municipality of Kétou in southern Benin. The objective was to assess the spatial distribution of drinking water supply structures and the satisfaction of the populations of the Municipality of Kétou in relation to the demand for drinking water. The spatial distribution, accessibility and overload of the functional drinking water supply structures were assessed using an approach based on thematic mapping and spatial analysis. The results obtained indicate that theinfrastructures are unevenly distributed over the territory of the Municipality of Kétou. The district of Adakplamè is the least  concentrated in hydraulic works while the district of Kpankou presents the greatest number of works. Accessibility as a function of the time required to reach the various structures is acceptable only in the districts to the south of the Commune. Functional structures are overloaded compared to service standards depending on the type of structure. In view of these findings, it is necessary to plan for theconstruction of new structures and to repair certain broken down infrastructures in order to cope with the increasing demands for drinking water in the Municipality.

Use and selection of sleeping sites by proboscis monkeys, Nasalislarvatus, along the Kinabatangan River, Sabah, Malaysia

The choice of a sleeping site is crucial for primates and may influence their survival. In this study, we investigated several tree characteristics influencing the sleeping site selection by proboscis monkeys (Nasalis larvatus) along Kinabatangan River, in Sabah, Malaysia. We identified 81 sleeping trees used by one-male and all-male social groups from November 2011 to January 2012. We recorded 15 variables for each tree. Within sleeping sites, sleeping trees were taller, had a larger trunk, with larger and higher first branches than surrounding trees. The crown contained more mature leaves, ripe and unripe fruits but had vines less often than surrounding trees. In addition, in this study, we also focused on a larger scale, considering sleeping and non-sleeping sites. Multivariate analyses highlighted a combination of 6 variables that revealed the significance of sleeping trees as well as surrounding trees in the selection process. During our boat surveys, we observed that adult females and young individuals stayed higher in the canopy than adult males. This pattern may be driven by their increased vulnerability to predation. Finally, we suggest that the selection of particular sleeping tree features (i.e. tall, high first branch) by proboscis monkeys is mostly influenced by antipredation strategies

Proactieve en gestructureerde zorg voor kwetsbare oudere patiënten in de eerstelijn: Achtergrond, opzet en uitvoering van een screenings- en zorgprogramma

De huidige zorg voor de oudere, kwetsbare patiënt is reactief, gefragmenteerd en voldoet niet aan de behoefte van de patiënt. Gezien de verwachte sterke toename van de groep thuiswonende, kwetsbare oudere patiënten is een transitie nodig naar proactieve en geïntegreerde zorg. In de hier beschreven studie onderzoeken we twee innovatieve interventies in deze zorg: een screenings- en monitoringsprogramma voor kwetsbare ouderen op basis van routine zorggegevens en een multidisciplinair interventie programma door een verpleegkundige ouderenzorg in de huisartsenpraktijk. De effectiviteit van de interventies wordt onderzocht in een drie-armige, cluster gerandomiseerde trial, die plaats vindt binnen 58 huisartsenpraktijken in Utrecht, de Bilt en Maarssenbroek. 3008 patiënten zijn geïncludeerd. Primaire uitkomstmaat is het effect van de interventies op de dagelijkse bezigheden, gemeten met de Katz vragenlijst. Secundaire uitkomstmaten zijn kwaliteit van leven, mortaliteit, opname in een verzorgings- of verpleeghuis, bezoek aan een spoedeisende hulp of huisartsenpost, opnames in het ziekenhuis en mantelzorgbelasting. In dit artikel beschrijven we de achtergrond, opzet en uitvoering van een proactief en gestructureerd screenings- en zorgprogramma voor kwetsbare thuiswonende ouderen. De resultaten van de interventies worden elders beschreven

Faecal particle size in free-ranging proboscis monkeys, Nasalis larvatus: variation between seasons

Reducing the size of food particles is crucial for herbivores. Seasonal dietary changes are known to influence animals’ chewing efficiency. Proboscis monkeys (Nasalis larvatus) are foregut fermenters, with a high chewing efficiency allowing them to achieve very fine faecal particles. In this study, we investigated how proboscis monkeys’ chewing efficiency varies between wet and dry seasons, hypothesising differences possibly related to diet change. Faecal particle size analysis is an established approach to estimate chewing efficiency in mammalian herbivores. We analysed 113 proboscis monkey faecal samples collected in the Lower Kinabatangan Wildlife Sanctuary, between 2015 and 2017. By following standard sieve analysis protocols, we measured a mean particle size MPS0.025–8 of 0.45 ± 0.14 mm, and confirmed a previous result that proboscis monkeys have a very low faecal MPS. This study highlights a seasonal influence on proboscis monkeys’ chewing efficiency, with smaller MPS (better chewing efficiency) during the wet season. During that time of the year, individuals may potentially change their diet, as all faecal samples contained intact seeds. Whether the seasonal MPS difference in proboscis monkeys is smaller than in other colobines due to their “rumination” strategy remains to be investigated

Seed dispersal by proboscis monkeys: the case of Nauclea spp.

Frugivorous vertebrates such as primates are important dispersal agents in tropical forests, although the role of folivorous colobines is generally not considered. However, recent studies reported seed dispersal by endo- and epizoochory in colobine primates, including the proboscis monkey (Nasalis larvatus), suggesting that the role colobines play in seed dispersal might have been underestimated. In the Lower Kinabatangan Floodplain in Sabah, Malaysian Borneo, we investigated whether seeds were still able to germinate after being ingested by proboscis monkeys. Faecal samples (n = 201) from proboscis monkeys were collected between 2015 and 2017. Intact seeds belonging to eight plant species were found in 77% of the faecal samples. Nauclea spp. were the most abundant plant species, accounting for 98% of all intact seeds. This study is the first to conduct germination trials on seeds defecated by proboscis monkeys. Higher germination success was recorded in ingested Nauclea spp. seeds than in control seeds, from both ripe and unripe Nauclea orientalis fruits (P < 0.001). Therefore, we suggest that proboscis monkeys play a role in seed dispersal by enhancing the germination success of defecated seeds for at least some plant species. Similar to other colobines, although proboscis monkeys may provide a lower contribution to seed dispersal (low seed diversity over short distances) than other sympatric frugivores, this study emphasises that proboscis monkeys do contribute to the dispersal of intact seeds, such as Nauclea spp., in potentially suitable riverine habitats

Proactive and integrated primary care for frail older people: design and methodological challenges of the Utrecht primary care PROactive frailty intervention trial (U-PROFIT)

<p>Abstract</p> <p>Background</p> <p>Currently, primary care for frail older people is reactive, time consuming and does not meet patients' needs. A transition is needed towards proactive and integrated care, so that daily functioning and a good quality of life can be preserved. To work towards these goals, two interventions were developed to enhance the care of frail older patients in general practice: a screening and monitoring intervention using routine healthcare data (U-PRIM) and a nurse-led multidisciplinary intervention program (U-CARE). The U-PROFIT trial was designed to evaluate the effectiveness of these interventions. The aim of this paper is to describe the U-PROFIT trial design and to discuss methodological issues and challenges.</p> <p>Methods/Design</p> <p>The effectiveness of U-PRIM and U-CARE is being tested in a three-armed, cluster randomized trial in 58 general practices in the Netherlands, with approximately 5000 elderly individuals expected to participate. The primary outcome is the effect on activities of daily living as measured with the Katz ADL index. Secondary outcomes are quality of life, mortality, nursing home admission, emergency department and out-of-hours General Practice (GP), surgery visits, and caregiver burden.</p> <p>Discussion</p> <p>In a large, pragmatic trial conducted in daily clinical practice with frail older patients, several challenges and methodological issues will occur. Recruitment and retention of patients and feasibility of the interventions are important issues. To enable broad generalizability of results, careful choices of the design and outcome measures are required. Taking this into account, the U-PROFIT trial aims to provide robust evidence for a structured and integrated approach to provide care for frail older people in primary care.</p> <p>Trial registration</p> <p><a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2288">NTR2288</a></p
