Planungshilfen zur Geschwisterkalbhaltung – Management und Kostenkalkulationen
(2022)
Im Rahmen der vorliegenden Bachelorarbeit wurden Planungshilfen entwickelt, die die praktische Umsetzung der Geschwisterkalbhaltung auf Milchvieh- oder Kooperationsbetrieben erleichtern sollen. Dabei sollen zum einen die Betriebsleiter*innen bei der Erarbeitung von betriebsspezifischen Szenarien für die potenzielle Geschwisterkalbhaltung unterstützt und zum anderen eine Berechnung der mit der Umsetzung verbundenen Kosten ermöglicht werden. Als Basis für die Entwicklung der Planungshilfen diente eine Literaturstudie. ...

Der Einfluss von Befahrung alter Rückegassen mit einem schweren Rückezug auf mechanische, strukturelle und funktionelle Eigenschaften eines mit Fichten bestockten Lössbodens in Abhängigkeit von der Fahrwerkkonfiguration
(2023)
Bei der maschinellen Holzernte mit schweren Holzerntefahrzeugen wird der befahrene Waldboden deformiert und damit potenziell in seiner forstwirtschaftlichen Produktivität eingeschränkt. Mögliche Lösungsansätze für diese unerwünschte Nebenwirkung des Technikeinsatzes sind die Beschränkung der Befahrung des Waldbodens auf permanenten Rückegassen und die Verwendung tragender Bogiebänder. Es besteht jedoch eine Forschungslücke zur Veränderung der physikalischen Eigenschaften von vorverdichtetem Boden bestehender Rückegassen ...

Income and price elasticities of animal food demand and welfare in Indonesian urban: an application of the LA-AIDS
(2022-12-30)
Protein consumption can be a measure of the welfare of society. Developed countries consume more protein than developing countries. This study analyzes the effect of rising prices and income on demand and welfare in urban Indonesia. The research data use the 2018 Household National Socio-Economic Survey (Susenas) data in household consumption and expenditure data collected by the Central Statistics Agency (BPS). The number of samples is 133,873 households. The demand systems approach uses the Almost Ideal Demand ...

Exploring inclusiveness of vulnerable and marginalized people in the cassava value chain in the Lake Region, Kenya
(2023-03-21)
Vulnerable and marginalised groups (VMGs) who comprise widows, orphans, people living with disability and HIV, have not been given sufficient attention in agriculture in sub-Saharan Africa (SSA) by policy makers, development partners, research, and extension, yet they comprise nearly one-quarter of all smallholder farmers. This study explored inclusion of VMGs in cassava value chain in the Lake Region of Kenya. Formal survey, focus group discussions (FGD), and key informant interviews (KIIs) were used to collect data ...

Sustainable Eating Futures: A Case Study in Saudi Arabia
(2022-10-25)
Food systems are central to human societies. Developing sustainable, nutritious, and healthy food systems will be crucial to accomplishing sustainable development goals. The multifarious politics underlying food production, distributions as well as consumption are often ignored. The present paper analyses different factors affecting food consumption in the local population of Saudi Arabia and relates them to the supply chain. Different futuristic scenarios are discussed to develop sustainable food consumption practices ...

Solar energy integration in agro-processing in the tropics: a case study of large and small-scale cassava processing
(2023)
Agro-processing is key to reducing post-harvest losses. Agro-processing is defined as a set of techno-economic activities applied to all the products originating from the agricultural farm, livestock, aqua cultural sources, and forests for their conservation, handling, and value-addi-tion to make them usable as food, feed, fibre, fuel, or industrial raw materials [12]. Processing can be sophisticated (relying on industrial plants and machinery) or simple (depending on the sun or indigenous small-scale processes). The ...

Economic evaluation of biological nitrogen fixation in flooded rice cultivation in subtropical lowlands
(2023-06-13)
This study aimed to assess the economic viability of biological nitrogen fixation in flood rice cultivation in subtropical lowlands. A field experiment of seven treatments was carried out during the cropping seasons 2015/16, 2017/18, 2018/19 and 2019/20 at the Lowland Experimental Station of Embrapa, in Pelotas, RS, Brazil. The evaluated treatments were: (1) negative control (without N and inoculant); (2) positive control with recommended N-fertilization (120 kg N ha-¹, without inoculant) (standard recommendation); ...

Effect of Fermentation on the bioactive compound of cocoa Beans: a systematic review and meta-analysis approach
(2023-05-30)
Several studies have found the effect of cocoa bean fermentation on bioactive compounds through various fermentation characteristics; however, none of these studies adopted the meta-analysis approach. The effect of cocoa bean fermentation on six bioactive compounds: epicatechin, catechin, total phenolic content (TPC), anthocyanins, theobromine, and caffeine were systematically reviewed. This study aims to determine which variables that can affect the loss of bioactive compounds during fermentation so that their ...

Identification of fungal pathogens causing postharvest rot of bulb onions (Allium cepa L.) in selected major growing regions of Kenya
(2023-06-27)
Rot is a major cause of bulb onion losses in Kenya, accounting for about 14 % of total postharvest losses. In Kenya, the fungi associated with bulb onion postharvest rot of onion postharvest rots are not well known. Therefore, this study aimed at identifying the fungal pathogens contributing to bulb onion postharvest rot in major growing regions of Kenya. Bulb onion samples were collected from seven major markets and isolates were obtained by cutting 3 mm tissue segments from the edges of rotten lesions. These were ...

Measuring the economic performance of smallholder organic maize farms; Implications for food safety and security
(2023-05-31)
The use of chemical inputs in conventional agriculture is associated with some health and environmental issues. This led to a call for more sustainable and environmentally friendly agriculture with no health issues. However, there is low participation in organic farming in Nigeria, which could be linked to less knowledge about its profitability. The study investigated smallholder organic maize farming profitability in Northern Nigeria. We employed descriptive statistics, profitability analysis, and a multiple regression ...
