  • ethnobotanical study of medicinal plants from degraded dry afromontane forest in northern ethiopia species uses and conservation challenges
    Journal of Herbal Medicine, 2016
    Co-Authors: Kidane Giday, Lutgart Lenaerts, Kindeya Gebrehiwot, Gidey Yirga, Bruno Verbist, Bart Muys
    Abstract:

    Abstract The large variation in climate, geology and Land Forms in Ethiopia has led to a great variety of ecosystems with high plant species diversity. The authors sought to provide a comprehensive documentation on forest based medicinal plants, indigenous knowledge, and conservation challenges in degraded dry afromontane forest in northern Ethiopia. Ethnobotanical data were collected using semi-structured interviews (n = 272) and focus group discussions (n = 26) with key informants. Frequencies were calculated and cross tabulated to see the medicinal value of plants found and effect of demographic characteristics on medicinal plants use. Thirty-four medicinal wild plants species belonging to 33 genera and 26 families used as cure for 35 human and livestock ailments were documented. Shrubs were dominantly used (48.8%), followed by trees (25.6%), and herbs (16.3%). The largest number of remedies (29%) was used to treat gastro-intestinal disorders followed by joint pain (25.8%). The administration routes for human medicines were oral (42%), traditional smoke bath (36%), dermal (7%), nasal (5%) and auricular (2%); while oral (32%), dermal (25%) and tie (27%) were for veterinary medicines. Leaves (33%), roots (22%) and stem (16%) were commonly used plant parts for herbal preparation. The authors suggest encouraging in situ conservation of the existing medicinal plants. As a result of heavy exploitation, many forest associated medicinal plants in the area, like Laggera tomentosa, Phytolacca dodecandra, Verbena officinalis, and Zehneria scabra are becoming rare and difficult to find. The authors suggest domestication of some of the wild medicinal plants by households or usage of communal Lands for long term conservation of the species and continued availability for the use by local communities.

  • estimating soil erosion risk and evaluating erosion control measures for soil conservation planning at koga watershed in the highLands of ethiopia
    Solid Earth, 2017
    Co-Authors: Tegegne Molla, Biniam Sisheber
    Abstract:

    Abstract. Soil erosion is one of the major factors affecting sustainability of agricultural production in Ethiopia. The objective of this paper is to estimate soil erosion using the universal soil loss equation (RUSLE) model and to evaluate soil conservation practices in a data-scarce watershed region. For this purpose, soil data, rainfall, erosion control practices, satellite images and topographic maps were collected to determine the RUSLE factors. In addition, measurements of randomly selected soil and water conservation structures were done at three sub-watersheds (Asanat, Debreyakob and Rim). This study was conducted in Koga watershed at upper part of the Blue Nile basin which is affected by high soil erosion rates. The area is characterized by undulating topography caused by intensive agricultural practices with poor soil conservation practices. The soil loss rates were determined and conservation strategies have been evaluated under different slope classes and Land uses. The results showed that the watershed is affected by high soil erosion rates (on average 42 t ha−1 yr−1), greater than the maximum tolerable soil loss (18 t ha−1 yr−1). The highest soil loss (456 t ha−1 yr−1) estimated from the upper watershed occurred on cultivated Lands of steep slopes. As a result, soil erosion is mainly aggravated by Land-use conflicts and topographic factors and the rugged topographic Land Forms of the area. The study also demonstrated that the contribution of existing soil conservation structures to erosion control is very small due to incorrect design and poor management. About 35 % out of the existing structures can reduce soil loss significantly since they were constructed correctly. Most of the existing structures were demolished due to the sediment overload, vulnerability to livestock damage and intense rainfall. Therefore, appropriate and standardized soil and water conservation measures for different erosion-prone Land uses and Land Forms need to be implemented in Koga watershed.

  • biogeography of the kimberley western australia a review of Landscape evolution and biotic response in an ancient refugium
    Journal of Biogeography, 2014
    Co-Authors: Mitzy Pepper, Scott J Keogh
    Abstract:

    Aim We review the biogeography of the Kimberley, with a particular focus on the geological and Landscape history of the region. We identified broad geological and biogeographical discontinuities across the Kimberley, and propose a number of testable hypotheses concerning how the evolution of these LandForms may have harboured and structured genetic diversity across the region. Location The Kimberley region, north-western Australia. Methods The literature available on the Kimberley is summarized, in particular regarding the evolution of Kimberley Landscapes and climate. Previous genetic work was assessed in order to establish whether common patterns exist, and to identify concordance with four putative broad-scale biogeographical breaks to be tested when appropriate fine-scale genetic data become available: (1) the geological division between the Kimberley Plateau and surrounding deformation zones of the King Leopold and Halls Creek orogens; (2) the east– west geological divide between different sandstone units of the Kimberley Plateau; (3) major drainage divisions and river courses; and (4) the previously defined bioregions and subregions of the Interim Biogeographical Regionalisation for Australia (IBRA), the Northern and Central Kimberley. Results Genetic patterns across a number of taxonomic groups in the Kimberley lend support to the four biogeographical scenarios we outline, and these now need to be tested with additional data. Main conclusions The biogeographical patterns emerging from studies of Kimberley biota are characterized by high endemism and deep divergences. In addition, a complex relationship between the Kimberley and other monsoon tropical bioregions and the adjacent deserts suggests multiple expansions into the arid zone, and vicariance and isolation in upLand refugia within the topographically complex region. Fine-scale genetic data are beginning to be accumulated for Kimberley taxa, and concordant phylogeographical patterns across disparate groups suggest that regional differences in geological structure and Land-Forms may have played an important role in shaping the distribution and evolutionary patterns of extant biota. Future palaeoecological, geomorphological and finer scale phylogenetic investigations based on increased sampling and emerging genetic technologies will shed more light on the evolution of the Kimberley biome amidst one of the greatest environmental changes in the Cenozoic: the widespread aridification of the Australian continent.
