Enlarging a training set for genomic selction by imputation of un-genotyped animals in populations of varying genetic architecture
(BioMed Central, 2013)
Background: The most common application of imputation is to infer genotypes of a high-density panel of markers on animals that are genotyped for a low-density panel. However, the increase in accuracy of genomic predictions resulting from an increase in the number of markers tends to reach a plateau beyond a certain density. Another application of imputation is to increase the size of the training set with un-genotyped animals. This strategy can be particularly successful when a set of closely related individuals are ...

Assessing the impact of agricultural drought on maize prices in Kenya with the approach of the SPOT-VEGETATION NDVI remote sensing
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2016-12-23)
The high cost of maize in Kenya is basically driven by East African regional commodity demand forces and agricultural drought. The production of maize, which is a common staple food in Kenya, is greatly affected by agricultural drought. However, calculations of drought risk and impact on maize production in Kenya is limited by the scarcity of reliable rainfall data. The objective of this study was to apply a novel hyperspectral remote sensing method to modelling temporal fluctuations of maize production and prices ...

Post-harvest handling practices and associated food losses in sweetpotato and cassava value chains of southern Ethiopia
(2018-02-12)
In dieser Studie wurden die Nachernte-Ketten von Süßkartoffel und Maniok in Südäthiopien untersucht. Schlüsselfaktoren, die für Nahrungsmittelverluste verantwortlich sind, wurden identifiziert und mögliche Verbesserungsmaßnahmen vorgeschlagen.
Es wurden innerhalb der Süßkartoffel-Wertschöpfungskette die landwirtschaftlichen Betriebe und der Einzelhandel mit einem Ausschuss von bis zu 20% bzw. 25% als "hot-spots"

Entwicklung eines Online-Messverfahrens zur Bestimmung des Bodenbedeckungsgrades bei der Stoppelbearbeitung zu Mulchsaatverfahren
(2010-08-13)
Die vorliegende Arbeit ist Teil eines Verbund-Forschungsprojektes mit dem Ziel, eine Präzisions-Bodenbearbeitung in Abhängigkeit von verschiedenen Bodenparametern sowie dem Bodenbedeckungsgrad zu realisieren. Ziel dieses Teilprojektes war die Bereitstellung einer Online-Messung des Bedeckungsgrades, um die Bearbeitungsintensität während der Feldüberfahrt regeln zu können: Ein Kamerasensor vorne am Schlepper ermittelt die Bodenbedeckung und ein Tiefen-Sollwert wird an das Regelsystem eines Gerätes zur teilfächenspezifischen ...

Agroecological transition in Southern Benin: What challenges for more efficient vegetable farming systems?
(2022-10-18)
In Benin, agroecological intensification and agroecological transition of vegetable farming systems is an undeniable necessity for achieving the objectives of food and nutrition security while preserving natural resources, human and animal health. The present study analyses vegetable farming systems in southern Benin, to highlight bottlenecks and challenges in the process of an agroecological transition and intensification of these systems. Data were collected with questionnaires and interview guides through individual ...

Entwicklung und Erprobung einer kognitiv-sensorischen Methodik für die Erhöhung der Reliabilität von erhobenen Daten in Bezug auf Nachhaltigkeit und Konsumentenverhalten in Deutschland und in der Ukraine
(2023)
Die menschlichen Sinne werden als Brücke zwischen der Mitwelt und dem menschlichen Körper sowie als entscheidender Faktor bei der Bildung von Ernährungserfahrungen beginnend schon im Mutterleib betrachtet. Diese Studie zielt darauf ab, wissenschaftlich zu untersuchen, wie der Wandel hin zu einer nachhaltigen Ernährung unterstützt werden kann, indem das Konsumentenverhalten sowie deren Flexibilität und Änderungsbereitschaft mithilfe einer neuen kognitiv-sensorischen Methode bewertet und bemessen wird.
Im Literaturteil ...

Global Peasants Rights: International Congress 2017
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2017-06)
“Reaffirming that all human rights are universal, indivisible, interrelated, interdependent and mutually reinforcing and must be treated in a fair and equal manner, on the same footing and with the same emphasis, and recalling that the promotion and protection of one category of rights should never exempt States from the promotion and protection of the other rights, recognizing the special relationship and interaction between peasants and other people working in rural areas, and the land, water, nature and territory ...

Lignocellulosic biorefinery with a thermo-biological pretreatment concept
(2023)
There is great interest, not only in technologically advanced societies, in developing innovative sources of raw materials, especially lignocellulosic biomasses such as cereal straw, which do not interfere with food production. In Germany, 4 – 9 million tons of cereal straw, mainly wheat, are utilized annually, corresponding to an energy potential of 57 – 129 PJ/a. Lignocellulose, found in plant cell walls, consists of hemicellulose, cellulose, and lignin, and it requires complex fractionation to enable its polymers ...

The effect of the addition of pineapple residue (Ananas comosus L.) on texture, physicochemical properties, and sensory acceptability of the plant-based minced meatball
(2023-05-14)
This study aims to develop plant-based meat alternatives with unique textures by adding pineapple residue at four different ratios (0, 5, 10, 15, and 20% w/w). The developed products' textures, sensory characteristics, nutritional values, and consumer acceptance were all assessed. The results showed that an increase in the pineapple residue content caused lightness (L*), redness (a*), as well as yellowness (b*) to increase. The textural properties of the plant-based minced meatballs in this study were relatively lower ...
