Upgrading Starchy Staples for Tackling Malnutrition in South-West Ethiopia
(2018)
Child undernutrition is a critical public health challenge in Ethiopia. One of the immediate causes of child undernutrition is inadequate dietary intake as a result of relying on one or few starchy staples. Utmost attention should be given to improving diets of infants and young children if significant and fast changes are to be seen in the reduction of undernutrition. This dissertation examines the potentials of utilising appropriate food processing technologies for developing upgraded food products for infants and ...

The role of price in consumers’ purchase decisions on organic food
(2018-05)
Trotz des über die letzten Dekaden anhaltenden Wachstums des Marktes für ökologische Lebensmittel bleibt der Sektor hinter seinem Potential zurück. Als wesentlicher Grund hierfür wird häufig der Preis von Öko-Lebensmitteln genannt, der von Konsumenten als zu hoch empfunden wird. Der derzeitige Stand des Wissens bietet jedoch kein klares Bild über das Verbraucherverhalten in Bezug auf den Preis von Öko-Lebensmitteln. Das Ziel dieser Dissertation ist daher, Erkenntnisse zur Preissensitivität von Verbrauchern bei ...

Development of Maize Post-harvest Loss Reduction Mechanism Owing to Mycotoxin-producing Fungi Contamination Along Agro-ecology and Supply Chain in Southwestern Ethiopia
(2018)
Kurzfassung In vielen ländlichen Gebieten Äthiopiens ist Mais mit seinem hohen Kalorienwert das vorherrschende Grundnahrungsmittel und zudem für die Landwirte eine wichtige Einkommensquelle. Hohe Nachernteverluste sind jedoch ein landesweites Problem, allerdings gibt es hierzu kaum belastbare Daten, die die Ausarbeitung einer Reduzierungsstrategie erlauben würden. Insbesondere gilt das für die Verluste durch Pilzbefall und die daraus folgende Mykotoxinbelastung, wie dies häufig in den heißen und feuchten Klimabereichen ...

Effect of different types of soil conditioners (plant-derived composts and animal manure) and application methods on quantitative and qualitative characteristics of tomatoes and selected soil parameters
(2018)
World population prospect has increased the need for food production, therefore ensuring the sustainable production of food has been of interest to researchers of agricultural sciences, as well as politicians, due to high demands by consumers in various countries in the world.
In this dissertation, we have investigated the effect of different types of composts, from residual biomass (household compost (HC), Spent mushroom compost (SMC) and Vermicompost (VC)), on different characteristics of plant and soil in organic ...

Boxwood Borer Heterobostrychus brunneus (Coleoptera: Bostrichidae) Infesting Dried Cassava: A Current Record from Southern Ethiopia
(2017-01-27)
Insect specimens of adult beetles and larvae of 7–9 and 9–10 mm length, respectively were collected from infested dry cassava at two locations from multiple stores in southern Ethiopia. The specimens were identified as Heterobostrychus brunneus (Murray, 1867) commonly known as boxwood borer and auger beetle. The study presents a current record of H. brunneus in Ethiopia, particularly in the context of infesting food products. Additionally, a wide geographical distribution of the pest was reviewed and presented in ...

Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities
(2016-11-19)
In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri-) urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso) and Tamale (Ghana). Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping ...

Participatory Mapping as an Approach to Identify Grazing Pressure in the Altay Mountains, Mongolia
(2018-06-11)
Sustainable rangeland management is crucial for maintaining forage resources in pastoral systems, globally. However, pastoral regions are often remote and therefore data poor when it comes to resource monitoring. We tested participatory mapping as a means to rapidly assess rangeland use to identify areas with high grazing pressure. Participatory geographic information system data and herbaceous biomass production data were collected and georeferenced to establish a grazing pressure index for a summer pasture in the ...
