Finding Spaces for Urban Food Production – Matching Spatial and Stakeholder Analysis with Urban Agriculture Approaches in the Urban Renewal Area of Dortmund-Hörde, Germany
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
Using the case of an economically declined neighbourhood in the post-industrial German Ruhr Area (sometimes characterized as Germany’s “Rust Belt”), we analyse, describe and conclude how urban agriculture can be used as a catalyst to stimulate and support urban renewal and regeneration, especially from a socio-cultural perspective. Using the methodological framework of participatory action research, and linking bottom-up and top-down planning approaches, a project path was developed to include the population affected ...

Effect of management strategies on the performance of ruminant livestock production systems and the safety of plant and animal products in the city of Sikasso, Mali
(kassel university press, 2012-05-02)
The regional population growth in West Africa, and especially its urban centers, will bring about new and critical challenges for urban development policy, especially in terms of ensuring food security and providing employment for the growing population. (Peri-) urban livestock and vegetable production systems, which can contribute significantly to these endeavours, are limited by various constraints, amongst them limited access to expensive production factors and their (in)efficient use. To achieve sustainable ...

Influence of quebracho tannin extract and activated charcoal on nutrient intake and digestibility, digesta passage, nitrogen balance, and quality of faecal excreta in goats
(kassel university press, 2015)
The current study investigated the possibilities of producing manure that meets the specific requirements of irrigated organic cropping systems under arid sub-tropical conditions.
Therefore, two trials with goats were conducted that investigated the impact of control diets on their digestibility and faecal concentration with the goal to lowerfaecal concentration levels and meet the requirements of irrigated organic cropping.
Feeding ruminants with condensed tannins (CT) will lower ruminal protein degradation, ...

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 ...

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 ...

Integrated bioenergy and food production
(2015)
Rising global energy needs and limited fossil fuel reserves have led to increased use of renewable energies. In Germany, this has entailed massive exploitation of agricultural biomass for biogas generation, associated with unsustainable farming practices. Organic agriculture not only reduces negative environmental impacts, organic farmers were also prime movers in anaerobic digestion (AD) in Germany. This study’s aim was to identify the structure, development, and characteristics of biogas production associated with ...
Dissertation
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 ...

Using Grass Cuttings from Sports Fields for Anaerobic Digestion and Combustion
(2017-03-18)
Sports fields provide a recreation space for citizens, but also generate grass biomass, which is cut weekly during the main seasons and therefore could be used in energy generation (combustion or anaerobic digestion). To evaluate the technical suitability of the grass cuttings, silage was produced from four sports fields during one vegetation period and investigated for relevant properties. Potential methane yield was determined with batch tests. Mean methane yield was 291.86 lN·kg−1 VSadded (VS, volatile solid). ...

Urban Agriculture Oriented towards Self-Supply, Social and Commercial Purpose: A Typology
(2016-08-17)
Urban agriculture, a dynamic multifunctional phenomenon, affects the spatial diversification of urban land use, its valorization and its governance. Literature acknowledges its contribution to the development of sustainable cities. The dimension and extent of this contribution depends significantly on the particular form and function of urban agriculture. However, the complexity of interests and dimensions is insufficiently covered by theory. This paper proposes a typology for urban agriculture, supporting both theory ...
