The circular economy and the water-food nexus
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-12-16)
The global economy is based on a take-make-consume and dispose model where natural resources are turned into products and the waste disposed of instead of being reused as a resource. In the Asia-Pacific region climate change along with rapid population and economic growth is resulting in increased demand for water and food, potentially leading to economic and political instability. Europe has developed policy and technological innovations that can facilitate the transition towards a circular economy where waste becomes ...

Silage von jung genutzter Luzere (Medicago sativa) als heimisches Proteinfutter in der ökologischen Geflügel- und Schweinefütterung
(2017-06-07)
Die EU-Öko-Richtlinien sehen in der Schweine- und Geflügelfütterung den Einsatz ökologisch und möglichst betriebseigener oder regional erzeugter Futtermittel vor. Außerdem ist ein tägliches Raufutterangebot obligatorisch. Luzerne, die jung geerntet wird, weist im Vergleich zu Sojakuchen und Erbsen pro 100 g Rohprotein (XP) hohe Lysin- und Methioningehalte auf. Da diese einheimische Pflanze in vielen ökologisch wirtschaftenden Betrieben Teil der Fruchtfolge ist, liegt es nahe, ihr Potential als Eiweißfuttermittel für ...

Entwicklung eines ökonomisch ausgerichteten Zuchtprogramms für die bedrohte Schweinerasse „Bunte Bentheimer“
(2016-03-03)
Das Ziel dieser Arbeit war, ein ökonomisch ausgerichtetes Zuchtprogramm für die bedrohte Schweinerasse „Bunte Bentheimer“ (BB) zu entwickeln. Ein wesentlicher Bestandteil von Zuchtprogrammen für bedrohte Rassen ist der Erhalt der genetischen Diversität durch Vermeidung von weiterer Inzucht und Reduzierung des Inzuchtzuwachses. In Kapitel 2 wurde die Population der BB unter Berücksichtigung der vorhandenen Abstammungsinformationen in Bezug auf genetische Diversität, Inzucht und Verwandtschaft analysiert. Durchschnittlicher ...

Are practice recommendations for the prevention of feather pecking in laying hens in non-cage systems in line with the results of experimental and epidemiological studies?
(Elsevier B.V., 2017-10-14)
Feather pecking (FP) in laying hens is an important animal welfare problem in practice, despite extensive research and increasing sources of advice for farmers. We aimed to give an overview over results from experimental and epidemiological studies. We included non-cage systems, covering the rearing and laying phase. The investigated factors were categorised into those with either good, contentious or no evidence regarding preventive effects on FP. Moreover, we wanted to know to what extent recommendations for farmers ...

How to measure dairy cows´ responsiveness towards humans in breeding and welfare assessment? A comparison of selected behavioural measures and existing breeding traits
(Elsevier B.V., 2017-08-08)
For dairy cattle breeding as well as animal welfare science reliability and validity issues regarding measures of cows’ responsiveness towards humans are relevant. The objective of this study was to investigate reliability and validity aspects of four selected behavioural measures at the feeding gate (BM) and to compare them with existing breeding traits and with observations of cows’ behaviour during milking. This included the analysis of criterion validity at animal and at herd level and of repeatability of the BM ...

Palm oil supply and demand characteristics and behavior: A system dynamics approach
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Like other commodities, palm oil is characterized by common commodity cycles in the market. However, in this study, we argue that the palm oil market has distinctive traits compared to other commodity markets with regard to the cobweb theorem by elaborating on the characteristics of the Malaysian palm oil market and its basic underlying behavior. In an attempt to understand the behavior of the industry, researchers had been changing the paradigm of modelling the palm oil market by using the operationally-based modelling ...

Use of aquagel-Polymer as a soil conditioner for celery plants grown in sand culture
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Celery plants were grown in ten liter black plastic containers filled with sand substrate then mixed with three levels of aqua gel-polymer. Three levels of irrigation water were applied by using drip irrigation for each aquagel-polymer treatment. The experiment was carried out at the Protected Cultivation Experimental Farm in Dokki, Giza, Egypt to determine celery growth and yield under different studied treatments. Various levels of aquagel-polymer as well as irrigation water levels were applied in a factorial design ...

Labelling schemes for organic food: Consumer attitudes, preferences and willingness-to-pay in six European countries
(2011-12-12)
Since July 2010, all pre-packed organic food produced in the European Union (EU) must carry the new mandatory EU logo for organic food. Voluntary organic labels (such as national governmental logos and logos of private farmers’ associations and control bodies) can still be used, but only in addition to the mandatory EU logo. This change in the regulatory environment of organic labelling raises a number of questions regarding consumer preferences for different kinds of organic certification logos, which the present ...

German consumers' attitudes and preferences with regard to organic food and food from different origins
(2016-06-23)
In dieser Studie geht es darum, ein umfassendes Bild bezüglich der Konsumenteneinstellungen, Präferenzen und Zahlungsbereitschaften für ökologisch produzierte Lebensmittel und Lebensmittel verschiedener Herkünfte in Deutschland zu erhalten. Obwohl die regionale Herkunft von Lebensmitteln nicht offiziell und einheitlich geregelt ist und keiner Zertifizierung unterliegt wie die ökologische Produktion von Lebensmitteln, zeigen nationale und internationale Studien gleichermaßen, dass Konsumenten bereit sind, mehr für ...

Wastewater Treatment Project for Palma Soriano, Cuba: Assessment of Cultural and Ecological Conditions
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2014-06-10)
The Palma Project is an experiment in the use of cultural identity as a social trigger to address ecological degradation. The research methodology draws from environmental, social and urban analyses to unveil the best strategy to address the ecological, river restoration and water treatment challenges in Berkeley, California’s “Sister City” in southeast Cuba, Palma Soriano. The objective is to provide a better quality of life and to create new opportunities for the local community to reconnect with natural cycles ...
