Authors: Shehzadi Samreen , Shah Zahir , Mohammad Wisal 
Published: February 2022

Description of the subject. Soil organic carbon (SOC) plays critical role in terrestrial carbon (C) cycling and is central to preserving soil quality, food security and environmental protection in agroecosystem. The prevailing soil and climatic conditions of cultivated and irrigated soils in warm semi-arid areas favor the rapid decomposition, mineralization and loss of SOC to the atmosphere which contribute to global warming. One potential strategy to address this C loss is the addition of organic amendments. Objectives. To investigate the effect of four contrasting organic wastes with and without NPK mineral fertilizer on SOC retention, water use efficiency (WUE) and wheat yield in irrigated wheat-maize cropping system. Method. A 2-year field experiment was conducted using four organic wastes included municipal solid waste (MSW), farm yard manure (FYM), sugar industry waste (filter cake) and maize cropping residues. All wastes were applied at 3 t C·ha-1 alone and with a full or half dose of NPK mineral fertilizer. Results. On average, among organic wastes as sole treatment, highest SOC content in the 0-15 cm layer was recorded in filter cake (6.5 t·ha-1) and MSW (5.9 t·ha-1). Addition of NPK fertilizer along with organic wastes, improved the SOC contents with the highest SOC (7.7 t·ha-1) by filter cake + full NPK treatment followed by the MSW + NPK (6.9 t·ha-1). On average, maximum wheat grain WUE (18 kg·ha-1·mm-1) and grain yield (4.8 t·ha-1) were obtained by MSW + full NPK treatment followed by filter cake + NPK. Conclusions. These results indicate that the targeted addition of organic wastes (filter cake or MSW) have the best potential for improving SOC retention, WUE and wheat yield in irrigated maize-wheat cropping system.

Introduction. De nos jours, la gestion des ressources forestières ne se focalise plus sur l’exploitation exclusive du bois d’œuvre, mais prend également en considération les produits forestiers non ligneux. Entandrophragma cylindricum (Sprague) Sprague, de son nom commercial « sapelli/sapele », de la famille des Meliaceae, illustre parfaitement cette situation. Le présent article fait un état de l’art des connaissances concernant E. cylindricum et présente quelques informations sur la chenille qui lui est inféodée. Littérature. Le sapelli est une des espèces ligneuses les plus exploitées d’Afrique centrale pour son bois d’œuvre. Il est répandu dans la forêt dense humide semi-caducifoliée du domaine guinéo-congolais. C’est une espèce semi-héliophile, son mode de dispersion est anémochore et sa phénologie est régulière. Selon la sylviculture appliquée, sa croissance en diamètre peut atteindre jusque 0,82 cm par an. Cette essence est également l’hôte d’une espèce de chenille comestible riche en protéines, Imbrasia oyemensis Rougeot. Fortement appréciée par les populations locales, cette chenille fait également l’objet d’un commerce régional et international. Enfin, l’écorce du sapelli est reconnue pour son intérêt ethnobotanique, particulièrement en médecine traditionnelle. Conclusions. Les informations tirées de la littérature ont permis de mettre en évidence certaines lacunes relatives à l’écologie et au mode de reproduction de cette espèce et, ceci, en dépit de son importance pour le commerce du bois. De plus, les inconnues quant à la productivité et la saisonnalité des chenilles d’Imbrasia oyemensis sur cet arbre nécessitent de développer des recherches complémentaires pour garantir la durabilité de l’exploitation simultanée de la ressource ligneuse et non ligneuse et pour proposer des modes de gestion concertés entre exploitants industriels et populations locales.

Description du sujet. Au Nord-Togo, particulièrement en milieu rural, les populations utilisent des biens d’espèces ligneuses et des services écosystémiques pour satisfaire des besoins multiples. Dans un environnement marqué par une déforestation accrue, se développe une pression anthropique croissante avec une incidence sur la vulnérabilité et la valorisation de ces ressources. Objectifs. Cette étude sur la diversité et les usages des ligneux permet d’apprécier la richesse floristique des terroirs et d’évaluer, à partir de quatre paramètres, la vulnérabilité des espèces répertoriées et connues des populations en zone de savane sèche. Méthode. L’approche méthodologique est basée sur des enquêtes ethnobotaniques et socio-économiques menées auprès de 14 groupes ethniques par interview individuel et au sein de « focus groups ». Les analyses ont porté sur des calculs de fréquences et d’indices de valeurs d’usage et d’importance des espèces répertoriées. Résultats. Au total, 149 espèces ligneuses utiles ont été identifiées et réparties en 45 familles. Neuf principaux usages reconnus sont relevés : alimentaire (69 espèces), médicinal (91 espèces), bois-énergie (57 espèces), fourrager (57 espèces), artisanal (37 espèces), soins hygiéniques (36 espèces), bois de service (40 espèces), rituel ou magico-spirituel (35 espèces) et cosmétique (26 espèces). Ces usages portent essentiellement sur les feuilles, racines, fruits, graines, fleurs, bois et écorces. Sur l’ensemble des espèces répertoriées, 42 (28 %) présentent un risque élevé de vulnérabilité, celle-ci étant évaluée sur base de quatre paramètres : la fréquence de citation, le nombre d’usages différents, l’organe collecté et le mode de collecte. Conclusions. L’étude montre que l’utilisation des espèces ligneuses varie selon le milieu géographique et la valeur d’importance des espèces explique la vulnérabilité de celles-ci dans la savane sèche.

Description du sujet. Cette étude détermine les conditions optimales d’utilisation de déjections de lapin dans la production de macroinvertébrés benthiques pour une production de poisson à faible cout. Objectifs. L’objectif de cette étude est la détermination de la dose optimale de déjections pour une production plurispécifique de macroinvertébrés d’eau douce. Méthode. Pour ce faire, six traitements dont un témoin ont reçu respectivement 0 %, 10 %, 25 %, 50 %, 75 % et 100 % de déjections par rapport au volume total de substrat. Les cultures ont été réalisées dans des seaux qui ont chacun reçu au total 10 dm3 de substrat, 16 dm3 d’eau de forage et 4 dm3 d’eau d’étang. La densité initiale d’ensemencement est de 6 ind·dm-2 d’Odonates et d’Annélides (soit 3 ind·dm-3, pour une profondeur de 0,5 m), 8 ind·dm-2 de Chironomidae (soit 4ind·dm-3) et 10 ind·dm-2 de Mollusques (soit 5 ind·dm-3). Les paramètres physico-chimiques et biologiques de la culture ont été suivis tout au long des 63 jours d’expérimentation. Résultats. Les densités les plus élevées de macroinvertébrés benthiques sont obtenues avec le traitement T2 (192 ± 1,20 ind·dm-2 de Chironomidae, 52 ± 0,8 ind·dm-2 de Mollusques, 6 ± 0,33 ind·dm-2 d’Odonates et 4 ± 0,33 ind·dm-2 d’Annélides soit, 96 ± 1,20 ind·dm-3 de Chironomidae, 26 ± 0,8 ind·dm-3 de Mollusques, 3 ± 0,33 ind·dm-3 d’Odonates et 2 ± 0,33 ind·dm-3 d’Annélides). La biomasse la plus élevée des Chironomidae et des Mollusques est obtenue avec T2, soit respectivement 728,1 ± 2,23 mg matière sèche·dm-2 et 699,98 ± 22,49 mg matière sèche·dm-2 (ou encore respectivement 364,05 ± 2,23 mg matière sèche·dm-3 et 349,99 ± 22,49 mg matière sèche·dm-3). Conclusions. Au regard de ces résultats, le traitement T2 (140 g de matière sèche·dm-2, soit 75 g de déjections de lapin sèches·dm-3 de substrat) constituerait la dose à recommander pour une production plurispécifique optimale de macroinvertébrés benthiques d’eau douce.

Pendidikan saat ini dipandang berjarak dengan realita kehidupan. Melalui pendidikan, sejatinya pelajar dapat memahami dan memaknai realita sosial dan menjadi bekal bagi mereka dalam menjalani kehidupan yang lebih bermakna. Karena itu, bentuk pembelajaran yang dianggap sesuai adalah pembelajaran kontekstual. Namun, pembelajaran kontekstual sering tidak menjadi prioritas sekolah dan pendidik karena prioritas utama adalah memenuhi standar kurikulum dan terbatasnya keahlian pengajar dan pendidik untuk menyediakan pendidikan yang sesuai dengan kehidupan dan realita yang dihadapi pelajar. Untuk melengkapi kekosongan penyediaan pendidikan kontekstual, diperlukan peran aktif berbagai kelompok, seperti universitas melalui kegiatan pengabdian kepada masyarakat untuk membantu pihak sekolah dasar dan menengah untuk menyediakan pengetahuan dan keahlian yang terhubung dengan pengalaman pelajar dan realita sosial, atau relevan dengan lingkungan alamiah mereka. Kegiatan pengabdian masyarakat yang dilakukan Jurusan Ilmu Hubungan Internasional dan Jurusan Teknik Informatika Unpar di pesantren Bani Yasin Sukabumi bertujuan untuk melengkapi pihak pesantren dengan pengetahuan dan pengalaman yang kontekstual. Di satu sisi, kegiatan ini memberikan pelajar muatan pendidikan lokal seperti pertanian, menjadi pekerja migran, literasi dasar, dan pengembangan nilai di ranah afektif. Pelajar dapat menghubungkan antara pengalaman dan kehidupan keseharian mereka dengan pengetahuan dan keahlian yang diberikan dalam suasana yang menyenangkan. Kegiatan ini juga mendorong pentingnya menekankan aspek partisipasi dan kerjasama universitas dengan pihak lain yang lebih berpengalaman dalam memberikan pengetahuan dan keahlian yang sesuai dengan kebutuhan pesantren, dalam hal ini yaitu pertanian. Di sisi lain, kegiatan abdimas ini terkendala situasi pandemi yang menghambat proses refleksi dan optimalisasi kreativitas pelajar untuk mengolah pengetahuan yang diperoleh dari interaksi ini ke dalam cara mereka menyelesaikan persoalan kehidupan.
Análisis del Marco Normativo de Economía Circular en Ecuador Orientado al Sector de los Plásticos
Authors: Portilla-Jiménez Jenny Gabriela 
Published: February 2022

A nivel mundial el sector industrial del plástico es uno de los sectores productivos más relevantes por generar empleo, satisfacer necesidades, solucionar problemas sanitarios entre otros; sin embargo, también genera un alto impacto negativo al ambiente lo que provoca problemas para el ser humano y las demás especies de flora y fauna, no solo en su fabricación (debido a la emisión de gases de efecto invernadero) sino también por los residuos plásticos generados por décadas que hoy en día contaminan ríos, laderas, quebradas, océanos, y otros ecosistemas marinos y terrestres. El crecimiento de la producción de plásticos en los últimos 65 años superó a cualquier otro material fabricado. Se estima que cerca de 8300 millones de toneladas métricas (Mt) de plásticos vírgenes se han producido hasta la actualidad. En Ecuador la realidad no es distinta, la producción, el consumo y la generación de desechos plásticos ha crecido de manera descontrolada, por lo que la generación y aplicación de normativas que regulen el comportamiento de la sociedad es absolutamente necesario y urgente. Por medio de la presente investigación se analizó el marco normativo ecuatoriano y cómo este apoya a la transición de una Economía Lineal a una Economía Circular en el sector del plástico, como una solución global a la gran contaminación que ha generado el plástico por décadas. Se realizó además, un análisis de los avances que el Ecuador está teniendo en el contexto de la sostenibilidad a partir de la generación de políticas de Economía Circular tomando como caso de estudio al sector industrial de plásticos, así como el nivel de aplicación de las mismas. Se concluye que a pesar de contar con un marco normativo sobre la aplicación de Economía Circular, a nivel general y en el sector plástico las iniciativas, proyectos y lineamientos son encaminadas al fomento del reciclaje y la incorporación de material reciclado posconsumo en la fabricación de los mismos productos de un solo uso, fomentando una cultura de comodidad y alejándose de una aplicación de los principios de Economía Circular. El país que debe iniciar su cambio cultural no solo en la gestión integral de residuos sino las políticas encaminadas a la producción e importación deben alinearse con el cumplimiento de los principios de la Economía Circular y el desarrollo sostenible.

Published: February 2022

The development of subak as tourist attraction will be inline within Bali cultural tourism development, since subak and tourism in Bali are both are Balinese culturally basis. This is an effort to maintain the sustainability of subak while controlling the paddy field conversion and supporting environmental sustainability. However, the absence of subak strategy as tourist attraction becomes a problem. This paper analyzes the internal and external environmental factors that influence Subak Padanggalak, Denpasar City, Bali as tourism attraction and designing the subak strategy as tourism attraction in urban area. To do so, it will be analyzed using SWOT and Quantitative Strategic Planning Matrix (QSPM). The I-E matrix analysis falls into cell V, namely using maintain subak as tourism attraction dan pushing market penetration and product development. SWOT analysis produces four alternative strategies, namely: (a) S-O strategy (expansion of tourist markets, provision of subak tourism facilities), (b) S-T strategy (stressing agricultural activities and rituals as tourist attractions, tourism activities based on subak norms and rules, involving subak members in subak tourism activities), (c) W-O strategy (subak is more involved in developing tourism attraction and cooperating with government), and (d) W-T strategy (strict rules for controlling land conversion, limiting the coming of external labor working in subak, and adequate facilities to empower farmers and foster public appreciation of subak). Priority analysis of the subak strategy successively starts from the development of tourist attraction based on agricultural activities and rituals in subak through cooperation with the government and entrepreneurs to empower farmers through providing additional sources of income from tourism activities. To ensure the sustainability of subak, it is necessary to have strict rules to control the conversion of agricultural land functions, and limit the external workforce to subak. The strategy must be is in line with subak norms and rules to achieve sustainability of subak-based urban tourism attraction. Keywords: attraction, Denpasar, development strategy, subak, tourism

Published: February 2022

Land-use change from a rubber plantation into the ITERA campus area causes an ecological transition. The components of ecology affected are vegetation and wildlife (bird). Geographic information systems can be used to assess the condition of vegetation and its relation to the ecological component. This study analyses bird diversity, vegetation condition through the NDVI value distribution, and then analyses the bird distribution based on vegetation condition. Observation in transect is the method for collecting bird distribution data. Analyses of vegetation condition was carried out based on NDVI. Analyses of bird distribution based on vegetation condition was carried out spatially by overlaying thematic maps of vegetation with bird distribution. This research found 28 bird species belonging to 18 families with diversity index (H’) 1.84. The highest abundance species were Lonchura punctulata, Passer montanus, and Hirundo tahitica. The NDVI values ranged from -0.64-0.87. ITERA vegetation conditions are divided into five classes: very rare vegetation (VRV), rare vegetation (RV), m vegetation (MV), dense vegetation class (DVC), and very dense vegetation (VDV). Total encounters with birds in this study were 753. The distribution of birds to the vegetation conditions in ITERA has a higher tendency and diverse vegetation have implications of birds to use the vegetation. In the VRV class, there were 4 encounters, RV 37, MV 157, DVC 235, and VDV 315. Also, the number of bird species tends to increase along with the increasing vegetation value. Lonchura punctulata is a bird with the highest abundance in each vegetation class, followed by Passer montanus and Pycnonotus aurigaster.
