RĂ©silience Communautaire Des Riverains Autochtones Batwa Dans Le Contexte Du Conflit Au Parc National De Kahuzi Biega, Est De La Rd. Congo
Introduction : Les délocalisations des peuples autochtones de leurs terres ancestrales en faveur de la création des réserves naturelles ou aires protégées datent de quelques siècles et se sont effectuées dans plusieurs pays. Elles ont suscité des conflits entre les peuples autochtones et les gestionnaires des aires protégées et produit un état de choc chez les autochtones riverains Batwa dans le cas de la RDC. L’étude vise à identifier les initiatives de résiliences communautaires développées par les riverains autochtones Batwa dans le contexte de conflits, dans la partie haute altitude du Parc National de Kahuzi Biega à l’Est de la RDC. Méthodologie : Les données utilisées dans cette étude ont été collectée au moyen des discussions de groupes menées, accompagnées des interviews approfondies avec certaines personnes ressources et les leaders autochtones Batwa. Résultat : Les résultats montrent que vingt-trois (23) initiatives résilientes communautaires ont été identifiées dont cinq (5) initiatives endogènes et dix-huit (18) exogènes. Les initiatives endogènes de résilience ont eu plus d’impact significatif dans le mode de vie des riverains autochtones Batwa que les initiatives exogènes de résilience. Conclusion: Les initiatives de résiliences communautaires auxquelles s’adonnent lesriverains autochtones Batwa dans le milieu d’accueil, sont juste à classer dans leur capacité d’adaptation et non de transformation dans l’hinterland du Parc National de Kahuzi Biega car cela nécessite les mécanismes de gouvernance, les politiques / réglementations, l'infrastructure, les réseaux communautaires et les mécanismes formels de protection sociale qui font partie du système plus vaste dans lequel les communautés doivent s’intégrer.
Introduction: The relocation of indigenous peoples from their ancestral lands in favor of the creation of reserves or protected areas dates back a few centuries and hastaken place in several countries. This has led to conflict between indigenous peoples and protected area managers. These evictions have produced a state of shock among the indigenous Batwa riverside dwellers. The study aims to identify community resilience initiatives developed by indigenous Batwa riverine dwellers in the context of conflict in the high altitude part of Kahuzi Biega National Park in eastern DRC. Methodology: The data used in this study was collected through focus groups discussion, accompanied by in-depth interviews with resource persons and Batwa indigenous leaders. Result: The results show that twenty three (23) community resilience initiatives were identified, including five (5) endogenous community resilience initiatives and eighteen (18) exogenous community resilience initiatives. The endogenous resilience initiatives had a more significant impact on the lifestyle of Batwa indigenous residents than the exogenous resilience initiatives. Conclusion: The community resilience initiatives that Batwa Indigenous neighbors are engaged in the host environment are aptly categorized as adaptive rather than transformative in the Kahuzi Biega National Park hinterland as this requires governance mechanisms, policies/regulations, infrastructure, community networks and formal social protection mechanisms that are part of the wider system into which communities need to integrate

Introduction: Women become vulnerable to certain pathologies during pregnancy in rural areas and the use of traditional pharmacopoeia using medicinal plants is the solution often adopted. This article focuses on the use of medicinal plants among pregnant indigenous Batwa women living around the Kahuzi Biega National Park (KBNP). The knowledge and practices of these women have enabled us to inventory and determine the different uses of these plants. Methodology: The data used in this study was collected by means of an ethnobotanical survey conducted using a questionnaire following the semistructured interview method. The data collected, which included ethnobotanical characteristics, were processed and analyzed with appropriate ethnobotanical and statistical software in order to select a few plants for future laboratory testing. Result: Most of the traditional practitioners interviewed were women (83.88%) and a large proportion of them (35%) were over 65 years of age. The plants used were classified according to the different stages of pregnancy development. Thus, Dichrocephala integrifolia, Kalanchoe pinnata, Pennicetum purpureum, Plantago palmata, Commelina difusa , Physalis angulata , Aloe barbadensis, Rumex bequaertii, Cannabis sativa, Carapa grandiflora Myrianthus arborea and Acmella caulirhiza have a 100% fidelity. The most commonly used organs are leafy stems (3714 %) and pressing (66, 6 %) is the most cited preparation technique. Conclusion: These results illustrate the richness of these peoples and these plant resources deserve scientific interest in order to be properly valorized

Community perceptions of the impact of war on unintended pregnancy and induced abortion in Protection of Civilian sites in Juba, South Sudan
Conflict and mass displacement into Protection of Civilian (POCs) sites in South Sudan led to the breakdown of community and family structures, increasing women and girls’ vulnerability to gender-based violence and exacerbating already poor sexual and reproductive health outcomes. As one component of a study on post-abortion care, this study explores community perceptions of unintended pregnancy and abortion in a POC in Juba. Four focus group discussions were conducted with 36 women and married men aged 18-45 living in the POC. Although initial reactions to induced abortion were generally negative, participants discussed that unintended pregnancy and induced abortion appeared to have increased during the current conflict. Their discussion of abortion became less condemnatory as they described changes in people’s situation due to war, including instability and poverty, transactional sex, disruption of marital norms, rape, and low contraceptive use. This is one of the first studies to investigate community perceptions and practices related to unintended pregnancy and abortion in South Sudan. Despite beliefs that these are taboo topics, the discussions provide an opening to reduce abortion stigma. To ensure lasting stigma reduction, investment in women and girls to improve gender equity is needed
Copepod diversity along the Congo River Basin: a first approach
peer reviewedThe free-living copepods of the Congo River Basin in Africa, the second largest in the world just after the Amazonas River Basin, are still insufficiently known because of problematic accessibility and complex logistics related to sampling. We analyzed samples from 82 sites obtained during expeditions in 2010 and 2013. The Congo River main channel and its main mouth tributaries (1700km; between Kisangani and Kinshasa), and the Kasai River and its main mouth tributaries (600km) were visited. A Schindler-Patallas trap was used in the open waters, with five samplings at each site. Twenty-five taxa were found, with dominance of immature forms (nauplii and copepodites). We recognized three undescribed species of Cyclopoida. The most speciose genera were: Microcyclops (five species), Mesocyclops, , and (three species each). The most frequent species were: Microcyclops varicans (27,6% of the samples) and Cryptocyclops sp. (10,6%). Few presumably cosmopolitan species were found, like pocyclops prasinus, , and Microcyclops varicans. Few diaptomid calanoids were found. Rarefaction and extrapolation curves revealed that the diversity found is about half that estimated considering just the open water species here studied. Spatially, the highest species richness was found in the main channel of the Congo River (23) compared to Kasai (20) and other tributaries (14, 9 from the Congo tributaries, 6 from the Kasai). The abundance of adult individuals was low, with an average of 2,36 individuals per sample when considering all water bodies. A distance-based redundancy analysis based on abundance and Bray Curtis dissimilarity index revealed two large groups of copepod species in the sites of the Congo main channel, plus two minor groups with mixed sites among Congo and Kasai main channels, and tributaries of both rivers, the latter being represented by small groups correlated with nitrogen forms, total phosphorus, and oxygen concentrations. Concerning the two large Congo´s channel groups of species, one was associated with water transparency, chlorophyll, and phytoplankton dominated by Dinophyceae, Chlorophyceae, Cryptophyceae, and diatoms. The other was correlated with conductivity, chlorophyll-a and Cyanophyceae. Kasai main channel sampling sites were dispersed among the four groups resulting from our analysis. Our results indicate that the copepod species in the area are separated into two large groups associated with black and white waters, with low and high primary productivity, respectively. The results showed a high copepod diversity along the Congo Basin as expected for large tropical rivers, and a low abundance for the adult copepods, as in other lotic environments. More species are expected to be discovered in this basin with the continuation of this investigation
Kajian potensi ekstrak bilberi sebagai penunjuk pH untuk memantau kesegaran makanan secara kromametri
Penunjuk pH sebagai suatu pendekatan untuk memantau kualiti atau kesegaran makanan semasa telah mendapat perhatian industri pembungkusan makanan. Penggunaan sumber semula jadi pigmen tumbuhan terutamanya daripada buah-buahan dan sayur-sayuran menjadi pilihan para pengguna untuk menggantikan pewarna sintetik dalam memastikan keselamatan makanan yang diambil setiap hari. Dalam kajian ini, ekstrak daripada bilberi telah digunakan sebagai pewarna sensitif pH. Perubahan warna sampel dikaji secara terperinci melalui kaedah kromametri dan juga kaedah spektrofotometri ultra-lembayung nampak. Warna merah terang terhasil dalam pH berasid, merah pudar pada neutral dan magenta ke kuning dalam pH beralkali. Keputusan kajian kromametri menunjukkan bahawa ekstrak bilberi berupaya mempamerkan perubahan warna yang jelas terhadap perubahan pH, iaitu terdapat perubahan nilai warna a* yang menyumbang kepada perubahan yang bererti dalam perbezaan warna keseluruhan (ΔE*). Nilai ΔE* juga ditentukan wujud hubungan linear dan kuantitatif terhadap julat pH tertentu. Oleh yang demikian, ekstrak bilberi didapati berpotensi sebagai bahan sensor untuk pH dalam membangunkan satu sensor pH bagi memantau kesegaran makanan terutamanya hasilan laut berbungkus memandangkan tahap kerosakan produk tersebut berkait rapat dengan perubahan pH ke arah alkali
Neotropical and Afrotropical freshwater copepods: recent advances
peer reviewedI present new perspectives and advances on the knowledge of free-living copepods in large tropical river basins. Currently, the greatest copepod diversity is known from the Palearctic region, with a surface about twice or thrice that of the Neotropical and Afrotropical areas, respectively. Interestingly, biological diversity estimators suggest a much higher and largely unexplored diversity in the two latter regions, potentially reaching or exceeding that of the Palearctic. I show trends for both regions, focused on Brazil and Congo Basins. Brazil comprises almost 40 % of the Neotropical region surface, including four rivers among the 20 largest in the world. Based on the literature review, there are 190 free-living copepod species in the country. Among the 12 hydrographic regions in Brazil, the richest are the Amazon and the Paraná basins, with the largest surface. Taxonomical studies on Brazilian copepods were predominant until 1979, yet, between 1980 and 1989 ecologically-oriented works were developed and became a main trend after 1990, representing over 80% of copepod studies after 2000. Molecular diversity and functional ecology are still poorly studied. Ecological studies with molecular-based diversity parameters, functional attributes or comprehensive spatialtemporal data of copepod species behavior and environmental variables have been used to detect effects of environmental changes both at population and community levels. Cyclopoid copepods composition and abundance changes according to the trophic level, but calanoids appear to be influenced by conductivity. The presence of cyanobacteria and phytoplankton of lower nutritional value can cause a bottom-up effect on the copepods, resulting in low functional diversity and increase of functional uniformity. Large filtering copepods can be replaced by small cyclopoids at increasing eutrophicated conditions. The Afrotropical region comprises four of the largest rivers worldwide. The most studied environments have been the great lakes of the rift valley (e.g. Tanganyika, Victoria, Kivu), the Nile River, and several places in South Africa. The Congo River, the second largest in the world, is almost entirely unknown in terms of copepod composition and ecology. Herein, I show initial data revealing the lack of knowledge of the l extant Congo copepod diversity, with a high potential for new species. Two expeditions made in 2013 and 2015 along the Congo and the Kasai River revealed 15 copepod species, but rarefaction and extrapolation diversity curves suggest the presence of at least double of this number. There are four large groups of copepods species in the Congo Basin, being the two largest separated by differences in primary productivity (white waters rivers) or microbial food web (black waters rivers). Copepods within the main channel of the Congo River seem to be less dissimilar than tributaries, thus reinforcing the effect of upstream basins, a trend observed in other large tropical river basins. Each large river has different copepod species especially for diaptomid calanoids and also for some Cyclopoida species, but just the last have shared species between Afrotropical and Neotropical regions. The river continuum and the flood pulse concepts were applied in these large tropical rivers, but both were disrupted by reservoirs. The large rivers of these tropical regions appear seem proportionally equal in copepod diversity according to this surface, and linked to their historical biogeography
