The groups of people in Omo valley, are facing the worst declining of the biodiversity and of indigenous practices, where the higher threat being man-made. Irrigation schemes for large-scale agriculture by the government like Kuraz Sugar Development Project (KSDP), with its planned 175,000 hectares of large-scale farmland and extensive implementation strategies is among the cause. United States Agency for International Development (USAID) and the UK’s Department for International Development (DFID) reported that it will have a profound impact on some of Ethiopia’s most important protected areas, including the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site, and the riparian forest along the Omo River. Besides, forced resettlement implementations are raised as the reason for human rights abuse in the area; most of the resettlement place doesn’t bear fertile agriculture and pastures as it is degraded and covered by invasive plant species. Hence ethnobotanical study and documentation of medicinal and wild edible plants used currently or in the recent past by the people of lower Omo valley, became our main objective, planned to collect ethnobotanical data of traditional knowledge of medicinal and wild edible plants, to conduct taxonomic identification and deposit samples of the claimed medicinal and wild edible plants in the National Herbarium of Addis Ababa University, to identify the threats and opportunities of indigenous knowledge and ecological conservation.

My research area of interest is renewable energy. Since energy is the engine of everything that does many works. For my research specifically on Organic Solar Cells’ power conversion performance using Plasmonic Nanoparticles at different layers of inverted Organic solar cells, I am studying the title « Unraveling Plasmon-Coupled Power Conversion Efficiency Enhancement in Wide-Band Gap Polymers-Based Organic Solar Cells: Both Experimental and Computational Approaches » at Addis Ababa University under the supervisors of Prof. Newayemedihin Aberra Tegegn and Dr. Nika Bekri Abdullah from Ethiopia. This study aims to solve the world’s energy problem and the Horn of Africa, which will contribute to the future of the rift specifically Ethiopia because Ethiopia is found in the Horn of Africa and is one of the parts of the rift.

I’ m interested in exploring and underscoring hominin behaviours in relation to food procurement strategies in the past, stone tools manufacture and the synergetic links between hominin-environmental interactions, cognition abilities and subsistence systems. Specifically, I uses phytolith analysis in combination with archaeological and plant micro-remains data in order to reflect the nature and type of environments that were occupied by early humans and the plant environments surrounding their habitats during the Pleistocene-Holocene epochs.

Based on the field trip experience, I observed the people were faced with a lot of climate uncertainties  » extreme weather events » leading to the occurrence of drought and flood interchangeable over years. The decline of natural resources within rift could be as a result of climate and environmental change which have been intensify by human activities. Other identify problems were as follows;

1. The Maasai pastoralist lived with their cattle’s within the rift which gave room for water contamination and other related sanitation issues resulting to water related illness among the populace which could affect their productivities (output).
2. The increasing population (human and animals) over the years could cause conflict between the farmers and pastoralist due to shrinking land for farming (rain fed agriculture) and grazing over the years.
3. There evidence of sheet and rill erosion process which could affect the fertility and condition of arable land for rain fed agriculture.
4. Depreciation of the ecological services within the Maasai conservation area of the rift was observe and needs urgent attention.
5. Drought and flood have affected the livelihood, health and well begin of the Massai people of the rift.
6. The people are living in hamlet and in dispersed form of settlement which could be difficult for the Narok government to provide preventive measures against diseases like malaria and water relate problems to the people.
7. There is need to understand the past climate before the development of the rift, present micro climate and predict what the future micro climate will be within the rift system. These will give more light on the implications

Thématiques de recherche : sociétés de chasseurs-cueilleurs de la fin du Pléistocène et du début de l’Holocène en Afrique. Je m’intéresse à l’organisation de la technologie lithique des chasseurs-cueilleurs, notamment à l’approvisionnement en pierre. Mes recherches explorent comment l’organisation technologique peut être étudiée pour comprendre les changements évolutifs et démographiques majeurs des cent mille dernières années en Afrique.

Actuellement conservateur des collections paléoanthropologiques au Musée National d’Ethiopie à Addis Abeba, et en doctorat au laboratoire PACEA à Bordeaux pour l’étude des fossiles africains d’hominines, notamment l’analyse 3D des dents.

J’étudie les pollens et les phytolithes en tant que marqueurs paléobotaniques des végétations passées dans le but de reconstituer les paléovégétations associées aux homininés du Mio-Pliocène et du Pléistocène en Afrique Centrale et de l’Est.

Je m’intéresse aux interactions plantes, végétation et climat actuel en zone tropicale, et à l’influence de ces trois facteurs sur les marqueurs botaniques pour tracer les changements climatiques et au sein des communautés végétales survenus dans le passé. Depuis 2018, je participe à la mission paléontologique OGRE dans la Formation de Shungura, Vallée de l’Omo, Ethiopie.
