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 ...

Natural and land-use drivers of primary production in a highly vulnerable region of livestock production (Sierras del Este – Uruguay)
(2019-02-21)
Sierras del Este is one of the two regions in Uruguay that are most vulnerable to climate change. A relevant vulnerability factor is the variability of the natural grasslands’ productivity. The objective of this study was to analyse the role of natural and land use drivers on grassland productivity as an essential factor for increasing the adaptive capacity of livestock production and reducing their vulnerability to extreme climatic events. The period 2000–2015 was analysed using the aboveground net primary production ...

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 ...

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 ...

Assessment of a pragmatic strategy to improve health of kacang goats in subsistence agricultural communities in Indonesian Borneo
(2019-11-22)
Poverty limits options available to smallholder, subsistence farmers to prevent or reverse livestock malnutrition and endoparasitism, two of the global drivers of goat morbidity and mortality in resource-constrained, tropical, agricultural communities. Our first study objectives describe changes observed in body condition and anaemia after implementation of three feasible and simple husbandry changes to improve health of smallholder herds of kacang goats in rural, Indonesian Borneo. These changes included routine ...

Untersuchungen zur Entwicklung einer wassersparenden Methode für die streifenförmige Beregnung von Dammkulturen im Feldgemüsebau
(2019-04)
Im Freilandgemüsebau der gemäßigten Klimazone Europas erhöhen Witterungsunsicherheiten und Trockenstress im Frühjahr und Sommer das Risiko für Ernteeinbußen und –ausfälle. Insbesondere bei im Dammanbau dicht unter der Oberfläche der Dammkrone gesäten Kulturen, wie beispielsweise der Möhre, besteht bei trockener Witterung die Gefahr eines ungleichmäßigen und verzögerten Auflaufens mit Folgen für die Bestandsentwicklung. Eine boden- und pflanzenschonende Beregnung der Dammkrone, die genügend pflanzenverfügbares Wasser ...

Physical and chemical optimisation of the seedball technology addressing pearl millet under Sahelian conditions
(Kassel University Press, 2019-01-16)
This study deals with the development of the seedball technology in particular for dry sowing under Sahelian conditions and pearl millet as crop. At first, our participatory evaluation in Senegal showed that (i) local materials needed for seedball production are locally available, (ii) the technology conforms to the existing management systems in the Sahel, and (iii) socio-economic conditions do not hinder seedball adoption. Afterwards, seedball was mechanically and chemically optimised. Pearl millet seedlings derived ...

Biofuels and livelihoods: Empirical findings on the welfare impacts of Jatropha cultivation in the Mangochi district, Southern Malawi
(2019-11-27)
This study evaluates the welfare impacts of jatropha (Jatropha carcus) cultivation measured as consumption expenditure per adult-equivalent for smallholders in southern Malawi. Household survey data from the southern region of Malawi collected in 2014 from 303 smallholders using purposive and random selection strategies were used. Propensity score matching and endogenous switching regression methods were employed to address the selection bias problem and to control for observed and unobserved covariate effects. The ...

What climate-smart agriculture means to members of the Global Alliance for climate-smart agriculture
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-06-05)
Climate-smart agriculture (CSA) is a recently proposed solution to address increasing concerns about food scarcity caused by climate change. The UN Food and Agriculture Organization defines CSA as an increase in agricultural productivity while adapting and building resilience to climate change and reducing greenhouse gas emissions, where possible. However, this definition of CSA and relevant methods are central to a debate between different groups of stakeholders, such as NGOs, policy-makers in developed and developing ...
