Robustness of portable and laboratory-based visible/near- and mid-infrared spectroscopy for optimized determination of temporally and spatially variable soil properties
(2021)
Application of visible/near- (VISNIRS) and mid-infrared (MIRS) spectroscopy to the field of soil science is promising, as it allows information about a range of properties to be collected simultaneously and rapidly, thereby providing high spatial and temporal resolution data for use in, e.g., soil mapping, precision agriculture, and long-term monitoring. However, investigation of the conditions under which visNIRS and MIRS can replace traditional lab methods is required, as the accuracy, robustness, and efficiency ...

Adoption and utilisation of Zai pits for improved farm productivity in drier upper Eastern Kenya
(2020-03-06)
Inadequate and poorly distributed rainfall and declining soil fertility have led to low crop productivity in most smallholder farms in sub-Saharan Africa. As a result, there has been a renewed quest for sustainable and resource-use efficient agricultural production practices. Zai pit technology is a practice that has the potential to alleviate water stress and enhance soil fertility. We assessed the factors that influence farmers' adoption and utilisation of Zai pits in Tharaka-Nithi County in upper Eastern Kenya. ...

Determinants of households’ membership in agricultural cooperatives in Bhutan
(2021-10-05)
The Royal Government of Bhutan has been promoting agricultural cooperatives (ACs) in the country; however, the number of people joining ACs is small. This study was conducted to identify the factors influencing households' decision to join ACs in Central Bhutan. A cross-sectional survey was conducted to collect data from 384 households (192 AC members and 192 non-AC members). Trained enumerators collected data in June and July 2018 using structured questionnaires. The binary logistic regression showed that households ...

Using Grass Cuttings from Sports Fields for Anaerobic Digestion and Combustion
(2017-03-18)
Sports fields provide a recreation space for citizens, but also generate grass biomass, which is cut weekly during the main seasons and therefore could be used in energy generation (combustion or anaerobic digestion). To evaluate the technical suitability of the grass cuttings, silage was produced from four sports fields during one vegetation period and investigated for relevant properties. Potential methane yield was determined with batch tests. Mean methane yield was 291.86 lN·kg−1 VSadded (VS, volatile solid). ...

Effects of three leafy vegetables on the growth performance of Giant African Snail Achatina (Lissachatina) fulica
(2019-06-07)
This present research was performed to evaluate the effects of three leafy vegetable diets [bitter leaf (Vernonia amygdalina), fluted pumpkin leaf (Telfairia occidentalis) and pawpaw leaf (Carica papaya)] on the growth performance of Giant African Snail (Achatina fulica). A total of ninety (90) A. fulica were used for the study. Thirty (30) snails each were subjected to three different dietary treatments in three replicates of 10 snails per replicate and fed with the fresh leaves of these vegetables over a period of ...

Food commercialization, hidden hunger and malnutrition: A study of food and nutrition security, focusing on the marginalized society in Sri Lanka
(2020-09)
From 2016 to 2019, a collaborative research project between the Rajarata University of Sri Lanka and the Department of Organic Food Quality and Food Culture, University of Kassel, Germany, was carried out to investigate the food commercialization, hidden hunger, and malnutrition in marginalized societies in Sri Lanka.
Consuming a healthy diet, maintaining good health, and chronic diseases is a challenge for those struggling with poverty and food insecurity for various reasons in Sri Lanka, including limited financial ...

Urban Agriculture Oriented towards Self-Supply, Social and Commercial Purpose: A Typology
(2016-08-17)
Urban agriculture, a dynamic multifunctional phenomenon, affects the spatial diversification of urban land use, its valorization and its governance. Literature acknowledges its contribution to the development of sustainable cities. The dimension and extent of this contribution depends significantly on the particular form and function of urban agriculture. However, the complexity of interests and dimensions is insufficiently covered by theory. This paper proposes a typology for urban agriculture, supporting both theory ...

Consumer insights that drive value creation opportunities in the Indonesian domestic apple supply chain
(2019-07-10)
Agrifood chains that are based on the values defined by end consumers are able to secure a competitive edge over other chains, but securing that competitive edge requires a thorough understanding of the consumers and their value preferences. This study was conducted with a view to understanding domestic apple consumers in Malang, Indonesia, and using that information to guide the opportunities for domestic apple supply chain development in Indonesia. Data were collected through an intercept survey of 200 apple ...

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 ...
