Crop Theft and Soil Fertility Management in the Highlands of Ethiopia

Theft of crops in rural areas is largely attributed to poverty and hunger. Crop theft has the consequence of soil fertility management being vastly impaired, a possible association examined by very few studies. The emphasis of most soil fertility studies has been on the effect of biophysical conditions and economics, which are the lack of capability of farmers as well as the failure of macro-economic policies to support good soil fertility management practices. The challenges that farmers face at the individual, household and community levels, as well as the barriers hampering farmers from practicing adequate soil fertility management, are still poorly understood. We need to extend our thinking beyond contextual issues of poverty, hunger, climate and seasonality to acquire a more nuanced understanding of food security in transforming rural agrarian societies. This study investigated the role of crop theft, particularly of legume bean crops, and its impact on soil fertility management. The results revealed that crop theft of legume bean crops deteriorated local intercropping and crop rotation soil fertility management practices. Crop theft had serious consequences on other socio-economic and cultural aspects of day-to-day life that deteriorated human relationships and eroded trust

Tackling Household Food Insecurity: The Experience of Vietnam

This paper is a systematic review of the facts and figures related to the issues of food security in Vietnam. Based on a comprehensive definition of food security as “access by all people at all times to enough, nutritionally adequate, and safe food for an active and health life†(Kennedy 2002), it describes and analyzes food security in connection with poverty or macro policies, in order to identify and understand thoroughly the problems related to food security. It shows that poor households are, per se, food-insecure, and that policies which target rapid economic growth using a socioeconomic approach help alleviate poverty and food insecurity. Its findings mainly confirm that household food security─specifically issues concerning food safety, availability, access, adequacy, and vulnerability ─ is still a vital concern in Vietnam.

Studying Resilient Action Strategies of First Line Managers

Background: One important key to an organization’s long-term competitiveness is the ability of first line managers (FLMs) to handle their role as a leader in daily work. FLMs main task is to contribute to a high and stable production output according to customer demands from an input that is characterized by instability and variability. To do so, FLMs must develop resilient action strategies – ways of working and daily problem solving that systematically facilitate to cope with instability. In this study protocol we present a methodological approach developed to evaluate and improve these. Methods/Design: The research approach is collaborative and developmental and performed together with two companies. The approach integrates and extends the theory and application of a model on interactive research and a framework on activity analysis. It will be applied using data collection techniques like interviews, diaries, observations, document analysis, and questionnaires. The analysis and development stages will be performed both separate and in collaboration in workshops and the result is planned to end up in the joint writing of a generic handbook on advantageous action strategies for FLMs’. Discussion: This study contributes with a new integration of two methodological approaches which provides a novel way to understand and develop dynamic on-the-job behaviour in work settings

Influence of socio-demographic factors on medicinal plant knowledge among three selected ethnic groups in south-central Ethiopia

Background The influence of socio-demographic variables was widely explored to evaluate their impact on indigenous and local ethnobotanical knowledge. However, the studies conducted in Ethiopia mainly focused on rural areas. They were limited to exploring and documenting ethnobotanical knowledge and the associated impacts of socio-demographic variables in rural-urban interface areas among ethnic groups. Hence, this study aimed to document plant-based indigenous and local ethnomedicinal knowledge and the associated impacts of socio-demographic variables among selected three ethnic groups in south-central Ethiopia. Methods Ethnobotanical data were collected using semi-structured interviews with 189 key informants, floristic species inventories, and field observations. Quantitative approaches were used to evaluate the use values (UV) of the most important medicinal plants, the informant consensus factor (ICF), fidelity level (FL), relative popularity level (RPL), and rank-order priority (ROP). Statistical tests were applied to evaluate the influences of socio-demographic factors and associations between variables on local ethnobotanical knowledge across ethnic groups in different informant categories. Results Statistical analysis revealed significant differences (p < 0.05) in the mean number of medicinal plants reported among age categories. There was also a positive association between the respondent's age and plant knowledge acquisition. Croton macrostachyus Hochst. ex Delile, Albizia gummifera C.A.Sm., Zingiber officinale Roscoe, Aloe macrocarpa Tod., Gymnanthemum amygdalinum (Delile) Sch.Bip., Calpurnia aurea (Aiton) Benth, and Allium sativum L. had the highest use values among ethnic groups. The highest informant consensus factor values were recorded for circulatory system disorders (0.68) followed by febrile illness and reproductive organ complications (0.66 each) across the three studied ethnic groups. The highest FL, RPL, and ROP values were noted for Lactuca inermis Forssk., Moringa stenopetala (Baker f.) Cufod., Withania somnifera (L.) Dunal, Allium sativum L., Citrus limon (L.) Osbeck, Ricinus communis L., Schinus molle L., Antiaris toxicaria (J.F.Gmel.) Lesch., Brucea antidysenterica J.F.Mill., Echinops kebericho Mesfin, Ocimum jamesii Sebald, Afrocarpus falcatus (Thunb.) C.N.Page, Searsia natalensis (Bernh. ex Krauss) F.A.Barkley, and Ricinus communis L. across ethnic groups in the study areas, which showed the conformity of knowledge on species curing potential and their prevalent uses. Conclusion The study revealed that the ethnic groups of Gedeo, Oromo, and Sidama have considerable indigenous and local ethnobotanical knowledge practices. Statistical analysis shown high variation in the acquisition of local ethnobotanical knowledge among age groups, which boosted our understanding of the effects of socio-demographic factors on the local ethnobotanical knowledge dynamics. Thus, this finding advocates for efforts to repair the observed generation gap via continued professional support and educating local communities to preserve traditional knowledge and practices through systematic documentation

Ethnobotanical study on medicinal plant knowledge among three ethnic groups in peri-urban areas of south-central Ethiopia

BackgroundDocumenting traditional knowledge on plant use among ethnic groups has enabled researchers to obtain a better understanding of how indigenous flora is seen and used in daily life. Their therapeutic applications will also encourage future conservation and phytochemical research, potentially leading to the development of novel drugs. However, past ethnobotanical studies conducted in Ethiopia mainly focused on rural areas, and limited coverage to document the ethnobotanical knowledge at the rural-urban interface. Therefore, this study was conducted to document and analyze traditional ethnobotanical knowledge on medicinal plants among three selected ethnic groups in peri-urban areas of south-central Ethiopia. In addition, we attempted to investigate the range of cultural similarity and disparity between the studied ethnic groups in relation to traditional medicinal plants and diseases treated.MethodsData were collected using semistructured questionnaires and in-depth interviews of 189 key informants, floristic species inventories, and field observations. Several cultural importance indices and Rahman's similarity indices were applied to analyze the relevance of medicinal plants and cultural similarity among the ethnic groups.ResultsA total of 189 therapeutic plants representing 159 genera and 69 families were identified and documented across the three studied ethnic groups. Of these, the Sidama, Gedeo, and Oromo ethnic groups reported 28, 34, and 38%, respectively. Most medicinal plants were represented by herbs (36%), followed by shrubs (31%), trees (27%), and herbaceous climbers (7%). Rahman's similarity index (RSI) revealed considerable ethnobotanical knowledge variation among ethnic groups. Oromo and Sidama showed the highest disparity (63.8%), followed by Gedeo and Oromo (63.2%). Of the total collected therapeutic plants, 78 most important medicinal plants were selected for the cultural importance analysis, which revealed that Croton macrostachyus Hochst. ex Delile scored the highest point in the Gedeo and Oromo ethnic groups and Zingiber officinale Roscoe in the Sidama ethnic group. Whereas Cinnamomum verum J.Presl, Psidium guajava L., and Melia azedarach L. are the least.ConclusionThe present study revealed the presence of cultural differences in medicinal plant knowledge practices and therapeutic plant use among the studied ethnic groups in rural-urban interface areas of south-central Ethiopia. The diverse healing potential of plants would support future pharmacological investigations, emphasizing the need for adequate documentation of indigenous knowledge and versatile flora to prevent their further loss
