A review of soil fertility management communication in sub-Saharan Afrika
(2021-02-12)
In sub-Saharan Africa (SSA), declining soil fertility is among the factors a ecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socioeconomic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM ...

Determinants of protected tomato production technologies among smallholder peri-urban producers in Kiambu, Kenya
(2021-03-05)
Climate variability and the rise in incidences of pests and diseases continue to undermine production of high value vegetables among smallholder farmers in sub-Saharan Africa. In order to respond to these challenges, protected farming technologies (PFT) (such as greenhouses) which modify the plant environment and therefore aid in avoiding the harmful eects of climatic factors have been promoted. Greenhouses protect the crops against high solar radiation and heavy rainfall that have the potential of destroying vulnerable ...

Dependency and economic benefits of use of wild food plants use among tribal communities in Malai Madeshawara Hills wildlife sanctuary, Southern India
(2021-01-31)
Wild food plant resources and their indigenous knowledge of use, are in danger of being lost in areas where rapid environmental and cultural transformations have led to changes in eating habits and practices. The study assesses the dependency and economic value of wild food plant use among forest-dwelling communities. Community perceptions are used to assess the use patterns and interrelations of human well-being. The data is collected through a combination of semi-structured interviews, household questionnaire survey, ...

Was steht dem Wissenstransfer zur Tiergesundheit in der landwirtschaftlichen Nutztierhaltung entgegen?
(2021-09)
Produktionskrankheiten sind (auch in der ökologischen) Nutztierhaltung weit verbreitet und werden in der Gesellschaft zunehmend als negativer externer Effekt wahrgenommen. Sie führen zum Einsatz von Antibiotika, sind Ausdruck eines beeinträchtigten Tierwohls und verursachen den landwirtschaftlichen Betrieben Ausfallkosten. Obwohl zu den Ursachen und der Vorbeugung viel geforscht wurde sind Produktionskrankheiten weit verbreitet. Ziel der vorliegenden Arbeit war es, den mit dem Begriff Wissenstransfer beschriebenen ...

Investigation of drying behavior and color development of beef slices for development of non-invasive monitoring approaches
(2021)
Meat drying has a long tradition worldwide and technically dried meat is increasingly valued as a low-fat snack or high-protein food product. Convection drying is widely used in industrial food preservation and has to provide high process efficiency and high product qualities, which can be contradictory. Therefore, it is important to understand the changes that occur in the product in order to develop drying strategies that consider process and product efficiency each at an acceptable level. The objective of this ...

Numerical Modeling and Characterization of Drying Process of Agricultural Products
(2021)
The main goal of this work was to experimentally characterize the hot air-drying process of agricultural products (Potato, Carrot, Tomato) and verify it with numerical solutions at single layer and industrial scale dryer using Comsol Multiphysics® 5.3.
Input parameters at single layer dryer effects on quality attributes were examined. Two strategies of drying were applied on batch dryer to examine the input effects on quality attributes. Constant input parameters strategy was designed by using central composite ...

The relation of food business with nature – an investigation of ecological accounts of the food industry
(2021)
Unternehmen sind angehalten, freiwillig oder gesetzlich, für ihre Handlungen Rechenschaft abzulegen. Nachhaltigkeitsberichte (Engl. sustainability reports oder ecological accounts) sind ein Weg aufzuzeigen, inwiefern sich unternehmerische Entscheidungen auf die soziale und ökologische Umwelt auswirken. Der Grund für die Untersuchung solcher ecological accounts im Rahmen dieser Dissertationsschrift ist der Einfluss von Lebensmittelunternehmen auf die soziale und natürliche Umwelt. Das Forschungsziel dieser Arbeit ist ...

Food rescue and donation in socioenvironmental policies on tackling food loss and waste: a systematic review
(2021-12-20)
In recent years, there has been an increasing concern among governments about food loss and waste – FL&W and, in this context, the food rescue and donation – FR&D has emerged in the scenario of socioenvironmental policies as a strategic factor for FL&W reduction. Despite FR&D have potential to establish a “win-win” arrangement between the spheres of waste management and demands of food security, it still has been perceived as a less attractive alternative than forwarding the surplus food to the waste treatment system. ...
