Effect of different types of soil conditioners (plant-derived composts and animal manure) and application methods on quantitative and qualitative characteristics of tomatoes and selected soil parameters
(2018)
World population prospect has increased the need for food production, therefore ensuring the sustainable production of food has been of interest to researchers of agricultural sciences, as well as politicians, due to high demands by consumers in various countries in the world.
In this dissertation, we have investigated the effect of different types of composts, from residual biomass (household compost (HC), Spent mushroom compost (SMC) and Vermicompost (VC)), on different characteristics of plant and soil in organic ...

Boxwood Borer Heterobostrychus brunneus (Coleoptera: Bostrichidae) Infesting Dried Cassava: A Current Record from Southern Ethiopia
(2017-01-27)
Insect specimens of adult beetles and larvae of 7–9 and 9–10 mm length, respectively were collected from infested dry cassava at two locations from multiple stores in southern Ethiopia. The specimens were identified as Heterobostrychus brunneus (Murray, 1867) commonly known as boxwood borer and auger beetle. The study presents a current record of H. brunneus in Ethiopia, particularly in the context of infesting food products. Additionally, a wide geographical distribution of the pest was reviewed and presented in ...

Effects of climate change on fungal community structure and organic matter turnover in soil profiles along elevation gradients in alpine ecosystems
(2019-10)
Although elevation patterns of diversity for plants and animals are well known, understanding of variations in fungal community structure along elevation gradients is limited. Soil fungi play an important role in soil microbial communities, where they improve soil organic matter (SOM) turnover and nutrient circulation. Hence, any change in fungal community structure will have strong effects on soil and ecosystem functioning. The main purpose of this thesis is therefore to investigate how climate induced shifts in ...

Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities
(2016-11-19)
In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri-) urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso) and Tamale (Ghana). Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping ...

Comparison of decent work status among smallholder pig farmers in Kenya; An empirical approach using Principal Components
(2019-11-07)
Agricultural production in Kenya is dominated by smallholder enterprises which provide up to 60% of the country's workforce. The agrarian transition to enhance smallholder participation in neoliberal capitalistic markets demands compliance to sanitary and phytosanitary standards and with codes for worker's welfare and thus the concept of decent work. Evaluation of decent work deficits in the informal economy however remains a challenge associated with sector uniqueness and differences in socio- cultural attributes ...

The eating culture of the Sundanese: Does the traditional salad (Lalapan) improve vegetable intake and blood β-carotene concentration?
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-09-12)
This study explores how consumption of the traditional salad Lalapan, central to the eating culture of the Sundanese, is associated with skin quality perception, daily β-carotene intake and blood β-carotene concentrations. This cross-sectional study was conducted in Gunung Malang Village and Leuweung Kolot Village, Bogor District, West Java. 60 healthy Sundanese women, aged 30-49 years, were selected using simple random sampling. Their body weight and height were measured, and they were interviewed about the eating ...

Distribution of Alternaria leaf blight of sunflowers caused by Alternaria alternata in South Africa
(2019-11-07)
Alternaria leaf blight (ALB) has been shown in recent years to be one of the major potential disease threats of sunflower capable of causing yield losses in all major production areas. The aim of this study was to determine the causal agent, prevalence and geographical distribution of ALB in the major sunflower production areas of South Africa. Surveys were conducted during 2012/13, 2013/14 and 2014/15 growing seasons at commercial sunflower production fields and at commercial cultivar trials. In the three growing ...

Biological control in pest management in Turkey: Comparison of the attributes of participant and non-participant greenhouse farmers in government-subsidized biological control practices
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-11-29)
The adoption of biological control methods is increasing in crop production due to concerns and awareness of consumers about food safety and pesticide residue conundrum. Biological control methods are a key component in pest management practices as they minimize the usage of pesticides, hence create less environmental and health problems. Biological control practices have been supported in Turkey since the year 2010 to ensure economical greenhouse production and to reduce the consumption of pesticides for sustainable ...

Participatory Mapping as an Approach to Identify Grazing Pressure in the Altay Mountains, Mongolia
(2018-06-11)
Sustainable rangeland management is crucial for maintaining forage resources in pastoral systems, globally. However, pastoral regions are often remote and therefore data poor when it comes to resource monitoring. We tested participatory mapping as a means to rapidly assess rangeland use to identify areas with high grazing pressure. Participatory geographic information system data and herbaceous biomass production data were collected and georeferenced to establish a grazing pressure index for a summer pasture in the ...
