A value chain analysis of baobab (Adansonia digitata L.) products in Eastern and Coastal Kenya
(2019-11-14)
A growing demand for the highly nutritious baobab fruit pulp from Europe and North America raises the question whether the marketing of baobab (Adansonia digitata L.) products could be an opportunity as an income source for rural communities in Kenya, or if the increased demand from overseas would disturb domestic baobab use. To gain an idea of domestic baobab use, a value chain analysis of edible baobab products was performed, using qualitative methods. By using a non-probability sampling, 134 baobab value chain ...

A sequence analysis of organic and conventional food consumers’ visual information acquisition
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-07-26)
It is of significant importance in food marketing to know which pieces of information available during shopping are most relevant to consumers. The visual search behaviour of consumers allows inference on the relevance of information based on what information is acquired and when. It is assumed that price is a major barrier to the purchase of organic food. However, little is known about consumers’ actual acquisition of information on organic food prices. To examine the information acquisition behaviour of consumers ...

Laying hen welfare -The prevention of feather pecking and keel bone damage
(2019-05)
Feather pecking (FP) and keel bone damage (KBD) are important animal welfare problems in laying hen housing, in both organic and conventional systems.
This PhD project aimed (1) to give an overview over results from scientific studies regarding factors with preventive effects on FP, and on the extent practice recommendations are based on this scientific evidence; (2) to identify further influencing factors on FP and to test the significance of the extent of compliance with recommendations; and finally (3) to discover ...

Africa’s future: Demarginalizing urban agriculture in the era of climate change
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-06-05)
Africans are migrating to cities. With the continent’s cities projected to double in population by 2050, the issue of food insecurity in urban areas is increasingly becoming a major concern. To sustain this urban explosion, the question of how to maintain constant food supply to urban residents remains an urgent priority since these locations do not always get access to adequate food. There has, however, been little work on examining urban agriculture (UA) as an alternative means of reducing hunger in Africa, especially ...

Factors influencing consumers’ gaze and purchase behavior for food products labeled with nutrition and health claims
(2019-11)
Short Summary:
The labeling of food products with a nutrition or a health claim is a widespread practice in the EU. These claims are short sentences on the front of food packages which highlight positive nutritional characteristics or beneficial health effects for the body. Research on nutrition and health claims shows a lack of consensus on whether these claims have a positive or a negative effect on consumers’ preferences and purchase behavior. Therefore, the research objective of this dissertation was to investigate ...

Quality of black bean seeds harvested with different moisture contents and submitted to two different storage systems
(2019-12-05)
Bean (Phaseolus vulgaris L.) is one of the main foods of the Brazilian diet. However, to achieve high yields, one of the determining factors is seed quality, which can be influenced by harvesting time and storage. The objective of this work was to evaluate the physical quality and physiological performance of black bean seeds as function of the moisture content at harvest and storage method. For that, black bean seeds, cultivar BRS Campeiro, were used. The harvest was performed when the seeds reached moisture contents ...

Applying Least Absolute Shrinkage Selection Operator and Akaike Information Criterion Analysis to Find the Best Multiple Linear Regression Models between Climate Indices and Components of Cow’s Milk
(MDPI, 2016-07-23)
This study focuses on multiple linear regression models relating six climate indices (temperature humidity THI, environmental stress ESI, equivalent temperature index ETI, heat load HLI, modified HLI (HLI new), and respiratory rate predictor RRP) with three main components of cow’s milk (yield, fat, and protein) for cows in Iran. The least absolute shrinkage selection operator (LASSO) and the Akaike information criterion (AIC) techniques are applied to select the best model for milk predictands with the smallest ...

Happy growers! Relationship quality in the German organic apple chain
(IFAMA, 2014)
Relational factors between supply chain actors have been acknowledged to contribute significantly to competitiveness.

Structured interviews were conducted with selected actors of the supply chain. Actors at all levels of the supply chain proved to be highly committed and described their business relations as satisfying and trustful. Strong vertical and horizontal ...
