Alternate furrow irrigation of four fresh-market tomato cultivars under semi-arid condition of Ethiopia – Part II: Physiological response
(Kassel University Press, 2016-11-14)
Understanding the variation in physiological response to deficit irrigation together with better knowledge on physiological characteristics of different genotypes that contribute to drought adaptation mechanisms would be helpful in transferring different irrigation technologies to farmers. A field experiment was carried to investigate the physiological response of four tomato cultivars (Fetan, Chali, Cochoro and ARP Tomato d2) to moderate water deficit induced by alternate furrow irrigation (AFI) and deficit irrigation ...

Towards an assessment of on-farm niches for improved forages in Sud-Kivu, DR Congo
(Kassel University Press, 2016-10-20)
Inadequate quantity and quality of livestock feed is a persistent constraint to productivity for mixed crop-livestock farming in eastern Democratic Republic of Congo. To assess on-farm niches of improved forages, demonstration trials and participatory on-farm research were conducted in four different sites. Forage legumes included Canavalia brasiliensis (CIAT 17009), Stylosanthes guianensis (CIAT 11995) and Desmodium uncinatum (cv. Silverleaf), while grasses were Guatemala grass (Tripsacum andersonii), Napier grass ...

Land use change from rainforests to oil palm plantations and food gardens in Papua New Guinea: Effects on soil properties and S fractions
(Kassel University Press, 2016-12-14)
Changes in soil sulfur (S) fractions were assessed in oil palm and food garden land use systems developed on forest vegetation in humid tropical areas of Popondetta in northern Province. The study tested a hypothesis that S in food gardens are limiting nutrient factor and are significantly lower than in plantations and forests. Subsistence food gardens are under long-term slash and burn practice of cropping and such practice is expected to accelerate loss of biomass S from the ecosystem. From each land use, surface ...

Pollination of Acacia woodlands and honey production by honey bees in Kitui, Kenya
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Acacia woodlands dominate arid and semi-arid areas across the world and are an important source of livelihood supporting activities. This is also the case in Kenya, where the Acacia woodlands are under pressure, partly due to the extractive activities that generate household income, such as collection of fuelwood, building poles, charcoal burning and livestock fodder. There is an apparent dilemma between the extractive and non-extractive use of the Acacia woodlands, and a need to develop income generating activities ...

‘Green Consumption’ beyond mainstream economy: A discourse analysis
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013)
In contemporary society, green consumption is a popular concept. The life styles of people and consumption behaviors are moderated in accordance to the ‘green ideology’. The process of green consumption can be observed through social behaviors such as preference of bio foods, recycling, reusing, limiting the over consumption and using environmentally friendly transport systems. However, mainstream economic analyses on green consumption argued that consumer behaviors are due to the rational choice of individuality ...

Vertical price linkages in food markets: Evidence from the tomato value chain of Northern South Africa
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Price transmission in agricultural fresh produce markets is a subject of considerable interest to policymakers given that improved market performance for agricultural commodities promotes market development and maximization of social welfare. In northern South Africa, where tomato production dominates the country, studies exist on the general production, marketing, and consumption of fresh produce. However, the literature lacks an analytical component that is pertinent to the mechanism of price transmission and ...

Assessment of genetic diversity in Agropyron desertorum accessions using ISSR molecular marker
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Molecular markers, such as Inter-Simple Sequence Repeats (ISSR), are relatively easy to use and are highly effective for genetic diversity studies. This research was carried out to evaluate polymorphism and variation among Agropyron accessions. Genetic variability was studied for 13 accessions of Agropyron desertorum using molecular markers. Genetic variations for 13 accessions were screened using 15 ISSR primers and 12 primers were scored. The ISSR primers produced 61 bands, of which the polymorphism was observed ...

Growing through Connections – A Multi-Case Study of Two Alternative Food Networks in Cluj-Napoca, Romania
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-03-12)
In a context of urgent global socio-ecological challenges, the aim of this paper has been to explore the potential of localised and socially connected food systems. More specifically, through a multi-case study of two alternative food networks in the city of Cluj-Napoca, Romania, their contribution to a sustainable food paradigm has been explored. An important synergy within the networks is how good food is equated with peasant produce, but issues regarding quantity, delivery arrangement, power relations and inclusiveness ...
