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 ...

How to tackle alveolar milk ejection problems during milking in dam rearing? Influence of different stimuli in the parlour and effects of half-day compared to free contact
(2018-07)
Dissertation Katharina Zipp 2018: Wie können Alveolarmilch-Ejektionsstörungen beim Melken bei muttergebundener Kälberaufzucht reduziert werden? Einfluss verschiedener Stimuli im Melkstand und Auswirkungen von halbtägigem im Vergleich zu freiem Kontakt
Bei der muttergebundenen Kälberaufzucht, bei der Milchkühe zusätzlich zum Melken ihre eigenen Kälber für mehrere Wochen säugen, kann die Menge der ermelkbaren Milch stark reduziert sein. Ein Grund hierfür sind Alveolarmilch-Ejektionsstörungen. Daher zielt diese ...

Morphological and Genetic Diversity of Sea Buckthorn (Hippophae rhamnoides L.) in the Karakoram Mountains of Northern Pakistan
(2018-07-30)
Sea buckthorn (Hippophae rhamnoides L.) is a dioecious, wind-pollinated shrub growing in Eurasia including the Karakoram Mountains of Pakistan (Gilgit-Baltistan territory). Contrary to the situation in other countries, in Pakistan this species is heavily underutilized. Moreover, a striking diversity of berry colors and shapes in Pakistan raises the question: which varieties might be more suitable for different national and international markets? Therefore, both morphological and genetic diversity of sea buckthorn ...

Estimation of Vegetable Crop Parameter by Multi-temporal UAV-Borne Images
(2018-05-22)
3D point cloud analysis of imagery collected by unmanned aerial vehicles (UAV) has been shown to be a valuable tool for estimation of crop phenotypic traits, such as plant height, in several species. Spatial information about these phenotypic traits can be used to derive information about other important crop characteristics, like fresh biomass yield, which could not be derived directly from the point clouds. Previous approaches have often only considered single date measurements using a single point cloud derived ...

Roots of symptom-free leguminous cover crop and living mulch species harbor diverse Fusarium communities that show highly variable aggressiveness on pea (Pisum sativum)
(2018-02-14)
Leguminous cover crop and living mulch species show not only great potential for providing multiple beneficial services to agro-ecosystems, but may also present pathological risks for other crops in rotations through shared pathogens, especially those of the genus Fusarium. Disease severity on roots of subterranean clover, white clover, winter and summer vetch grown as cover crop and living mulch species across five European sites as well as the frequency, distribution and aggressiveness to pea of Fusarium spp. ...

Lesson learnt from Smart Rice Actions in Indonesia
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Smart Rice (SR) actions are innovative farming practices derived from climate smart agriculture (CSA) concepts and are directed to comply with mitigation and adaptation strategies to climate change. This study provided information about the plausible implementation of SR actions in Indonesia based on literature reviews and stakeholders’ consultation with key informants work- ing on crop management and climate information. The SR actions recommendations are a set of farming practices applied to fulfill the needs of ...

Carbon footprint for wheat and corn under Egyptian condition
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Egypt agriculture is facing a great joint challenge of ensuring food security and mitigating greenhouse gas emissions under climate change. Characterizing the carbon footprints of crop production by life cycle analysis is be critical for identifying the key measures to mitigate greenhouse gas emission while sustaining crop productivity in the near future. Agriculture contributes a significant share of greenhouse gas emissions and concurrently represents a carbon dioxide (CO2) sink; it thus has two fold opposing impacts ...

Aqueous Leaching Prior to Dewatering Improves the Quality of Solid Fuels from Grasslands
(2018-04-04)
Renewable energies are necessary to reduce greenhouse gas emissions in energy production, and biomass plays a dominant role in the renewable energy sector. Combustion of biomass constitutes an efficient conversion technique, but is hindered by harmful elements which are frequently contained in residual grassland biomass. We investigated the effect of leaching on solid fuel quality with three independent experiments including the following treatments: (1) with or without leaching, (2) with leaching at various water ...

Farmers’ Perception of Water Quality and Risks in the Mashavera River Basin, Georgia: Analyzing the Vulnerability of the Social-Ecological System through Community Perceptions
(2018-08-28)
Competing natural resources usage that leads to dramatic land use changes can threaten the balance of a social-ecological system. When this is the case, communities are directly exposed to the negative consequences of those land use changes. The Mashavera River Basin is considered one of the hotspots of environmental pollution in Georgia. This is of importance for public health because the food production from this basin meets a substantial proportion of the country’s food demand. The farmers’ perception of the water ...
