Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The practice of closing an area from human and animal intereference to restore degrded lands is becoming a common and cultural practice in the degraded drylands of Ethiopia, particulraly in Tigray. The recovery and restoration of vegetation is fast and cheap compared to planting in these areas. Areas which have been fragile are now put under area enclosures and easily restored. It is taken as one of the best tool for the restoration of degraded drylands. In addition to the economic importance obtained throught the collection of grass and wood, local people admired for the ability of the enclosures to quickly restore local biodiversity. It has become a common phenomenen to observe accelaration of plant, but also animal, diversity with time, after the establishement of enclosures. In areas where they had been established, enclosed areas are among the green spots.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Oxytenanthera abyssinica is known to be one of the lowland perennial grass species in Ethiopia. This study was conducted to assess its woody species diversity based on homestead agroforestry system, carbon sequestration potential and its socioeconomic benefits at Tselemti district. A total of ninety nine plots, ninety from less than five year, five to ten years and greater than ten years domestication of O. abyssinica based homesteads and one exclosure with nine plots as comparison were taken. In total, 27 culms were randomly selected for biomass and carbon stock determination using three levels of age and three DBH levels. A total of 153 households were surveyed to assess socioeconomic benefits of O. abyssinica. The study revealed that species density, richness and diversity were significantly higher in the exclosure than in the three homesteads (p0.000). Carbon stock was significantly higher in one to three and greater than three years than less than one year culm age (P0.001).This study confirmed that woody species diversity was higher for those households that domesticate O. abyssinica on their homesteads earlier than those households that domesticate later.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Oxytenanthera abyssinica est reconnue comme l'une des espèces de graminées vivaces des plaines en Éthiopie. Cette étude a été menée afin d'évaluer la diversité des espèces ligneuses associées au système agroforestier des exploitations familiales, le potentiel de séquestration du carbone et les avantages socio-économiques de cette espèce dans le district de Tselemti. Au total, 99 parcelles ont été sélectionnées : 90 provenant d'exploitations familiales cultivant O. abyssinica depuis moins de cinq ans, entre cinq et dix ans et plus de dix ans, ainsi qu'une zone d'exclusion comprenant neuf parcelles à des fins de comparaison. Au total, 27 tiges ont été sélectionnées au hasard pour déterminer la biomasse et le stock de carbone en utilisant trois tranches d'âge et trois niveaux de diamètre à hauteur de poitrine (DBH). Au total, 153 ménages ont été interrogés pour évaluer les avantages socio-économiques d'O. abyssinica. L'étude a révélé que la densité, la richesse et la diversité des espèces étaient significativement plus élevées dans la zone d'exclusion que dans les trois exploitations (p < 0,000). Le stock de carbone était significativement plus élevé pour les tiges âgées de un à trois ans et de plus de trois ans que pour celles âgées de moins d'un an (P < 0,001). Cette étude a confirmé que la diversité des espèces ligneuses était plus élevée pour les ménages ayant domestiqué O. abyssinica sur leurs parcelles plus tôt que pour ceux l'ayant fait plus tard.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - L'Oxytenanthera abyssinica è nota per essere una delle specie erbacee perenni di pianura presenti in Etiopia. Questo studio è stato condotto per valutare la diversità delle specie legnose presenti nel sistema agroforestale delle fattorie, il potenziale di sequestro del carbonio e i benefici socioeconomici nel distretto di Tselemti. Sono stati presi in esame un totale di novantanove appezzamenti, novanta dei quali con un periodo di domesticazione dell'O. abyssinica inferiore a cinque anni, compreso tra cinque e dieci anni e superiore a dieci anni, oltre a un'area di esclusione con nove appezzamenti a scopo di confronto. In totale, sono stati selezionati casualmente 27 fusti per determinare la biomassa e lo stock di carbonio utilizzando tre fasce di età e tre livelli di DBH. Sono state intervistate 153 famiglie per valutare i benefici socioeconomici dell'O. abyssinica. Lo studio ha rivelato che la densità, la ricchezza e la diversità delle specie erano significativamente più elevate nell'area di esclusione rispetto alle tre fattorie (p.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - A Oxytenanthera abyssinica é conhecida por ser uma das espécies de gramíneas perenes das planícies da Etiópia. Este estudo foi realizado para avaliar a diversidade de espécies lenhosas com base no sistema agroflorestal de propriedades rurais, o potencial de sequestro de carbono e os seus benefícios socioeconómicos no distrito de Tselemti. Foram analisadas um total de noventa e nove parcelas, noventa provenientes de propriedades rurais com domesticação de O. abyssinica com menos de cinco anos, entre cinco e dez anos e mais de dez anos, e uma área de exclusão com nove parcelas para efeitos de comparação. No total, foram selecionados aleatoriamente 27 colmos para a determinação da biomassa e do stock de carbono, utilizando três níveis de idade e três níveis de DBH. Foram inquiridas 153 famílias para avaliar os benefícios socioeconómicos da O. abyssinica. O estudo revelou que a densidade, riqueza e diversidade de espécies eram significativamente mais elevadas na área de exclusão do que nas três propriedades rurais (p<0,000). O estoque de carbono foi significativamente maior em colmos com idade de um a três anos e superior a três anos do que em colmos com menos de um ano (P < 0,001). Este estudo confirmou que a diversidade de espécies lenhosas era maior nas famílias que domesticaram a O. abyssinica nas suas propriedades mais cedo do que nas famílias que o fizeram mais tarde.…
