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 ...

Linking sustainable diets to the concept of food system sustainability
(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)
Based on insights from an ongoing research project on food sustainability, we argue that discussing sustainable diets in isolation from food systems poses risks. Among these risks are making healthy diets exclusive, or ignoring externalities like biodiversity loss, land concentration, and encroachment on commons. Case studies from Bolivia and Kenya show how marked shifts from traditional to more uniform diets rich in sugar, salt, and fatty acids come with a radical transformation of food systems. Systems formerly ...

Seaweed farming as a sustainable livelihood option for northern coastal communities in Sri Lanka
(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)
Sri Lanka has recently contributed to the growing significance of seaweed farming in the globe. This study attempted to assess the financial feasibility, employment generation, perceived importance, social acceptability and major constraints associated with seaweed farming in the Northern part of Sri Lanka. The study sample included 160 seaweed farmers from the area. A questionnaire survey, in-depth interviews and focus group discussions were conducted to collect data and information. Descriptive analytical, investment ...

Typological characterisation of farms in a smallholder food-cash crop production system in Zimbabwe – opportunities for livelihood sustainability
(Kassel University Press, 2018-09-11)
The diversity of smallholder farms in space, resource endowment, production and consumption decisions are often a hindrance to the design, targeting, implementation and scaling out of agricultural development projects. Understanding farm heterogeneity is crucial in targeting interventions that can potentially contribute to improved crop productivity, food security and livelihood sustainability. The study sought to define and understand farm typology in a resettlement smallholder food-cash crop production area in ...

Applying phosphorus indices at a small agricultural watershed in Southern Brazil
(Kassel University Press, 2018-04-04)
Best management practices at watershed scale are essential to mitigate water pollution. The objectives of this study were: (1) to estimate the P-index in a small watershed with intensive agricultural use applying five P-index versions at three scales (watershed, sub-basin and agricultural field); (2) to assess the effect of the connectivity factors (distance between the agricultural field and the stream and width of riparian native vegetation) in estimating the risk of P loss. The five P-index versions resulted in a ...

Motivations to consume agroecological food: An analysis of farmers’ markets in Quito, Ecuador
(Kassel University Press, 2018-08-21)
This paper examines the motivations to consume agroecological foods in Quito, Ecuador. Using data from a survey (n = 254) conducted among the customers of farmers’ markets, the results reveal that agroecological consumers are substantially different from the rest of the population in terms of education, income and life style. The perceived healthiness of agroecological food is by far the main motivation to buy at farmers’ markets, with environmental concern as the least important motivation. In terms of who spends ...

Impact of agricultural activities on pesticide residues in soil of edible bamboo shoot plantations
(Kassel University Press, 2018-04-04)
Edible bamboo shoot is one of the most important vegetables in Asian countries. Intensive agricultural management measures can cause many negative influences, such as soil acidification and excessive pesticide residues. In the present study, more than 300 soil samples were collected from edible bamboo shoot plantations in six areas throughout Zhejiang province, China, to investigate the soil pesticide pollution and its change after different agricultural activities. Thirteen organic chemicals were detected; nine less ...

Mathematical Models in the Description of Pregnane X Receptor (PXR)-Regulated Cytochrome P450 Enzyme Induction
(2018-06-15)
The pregnane X receptor (PXR) is a drug/xenobiotic-activated transcription factor of crucial importance for major cytochrome P450 xenobiotic-metabolizing enzymes (CYP) expression and regulation in the liver and the intestine. One of the major target genes regulated by PXR is the cytochrome P450 enzyme (CYP3A4), which is the most important human drug-metabolizing enzyme. In addition, PXR is supposed to be involved both in basal and/or inducible expression of many other CYPs, such as CYP2B6, CYP2C8, 2C9 and 2C19, CYP3A5, ...
