Aqueous Leaching Prior to Dewatering Improves the Quality of Solid Fuels from Grasslands
(2018-04-04)
Renewable energies are necessary to reduce greenhouse gas emissions in energy production, and biomass plays a dominant role in the renewable energy sector. Combustion of biomass constitutes an efficient conversion technique, but is hindered by harmful elements which are frequently contained in residual grassland biomass. We investigated the effect of leaching on solid fuel quality with three independent experiments including the following treatments: (1) with or without leaching, (2) with leaching at various water ...

Human and farm influences on dairy cows' responsiveness towards humans - a cross-sectional study
(2018-12-31)
The human-animal relationship can have a major impact on cow welfare and stockpersons´ work safety and quality. This cross-sectional study investigated possible effects of stockperson and farm related factors on cows´ behaviour towards humans in different test situations on a range of farm types including farms with automatic milking system. On 32 dairy farms, cows´ avoidance distances (AD), tolerance to tactile interactions (TTI), behavioural reactions during and after release from restraint (RB) and expressive ...

Effects of Water Quality and Post-Harvest Handling on Microbiological Contamination of Lettuce at Urban and Peri-Urban Locations of Ouagadougou, Burkina Faso
(2018-12-16)
Vegetable production in urban gardens of Ouagadougou contributes to food security, but water for irrigation is often of low quality. This is particularly acute if irrigation water is taken from wastewater polluted channels. This study aimed at (i) verifying to what degree irrigation water quality is correlated with contamination of lettuce with Escherichia coli, total coliforms, and Salmonella spp., and (ii) assessing effects of post-harvest handling on pathogen development during the trade chain. We tested pathogen ...

Water Quality in Surface Water: A Preliminary Assessment of Heavy Metal Contamination of the Mashavera River, Georgia
(2018-03-23)
Water quality contamination by heavy metal pollution has severe effects on public health. In the Mashavera River Basin, an important agricultural area for the national food system in Georgia (e.g., vegetable, dairy and wine production), water contamination has multiple influences on the regional and country-wide health. With new industrial activities in the region, sediment extraction, and discharge of untreated wastewater into the river, its tributaries and irrigation canals, a comprehensive study of water quality ...

A Paradigm Shift in Water Quality Governance in a Transitional Context: A Critical Study about the Empowerment of Local Governance in Georgia
(2018-01-01)
The management of water quality is an important part of natural resource governance. Assurance of water quality therefore requires formulation of the regulatory framework and institutional process. Water quality-related problems and their management are mainly recognized as local responsibilities in Integrated Water Resources Management (IWRM). The politics of environmental policy-making should consider the political economic dynamics and socio-ecological patterns. Decentralization by providing more power to the local ...

Nutrition Transition and Traditional Food Cultural Changes in Sri Lanka during Colonization and Post-Colonization
(2018-07-13)
Sri Lanka was a colony of the Portuguese, Dutch, and British. The simplification of Sri Lankan food culture can be seen most clearly today, including how the diet has been changed in the last 400 years since the colonial occupation began. Therefore, greater efforts must be made to uncover the colonial forces that have undermined food security and health in Sri Lanka. Also traditional eating habits, which are associated with countless health benefits, have been gradually replaced by the globalized food system of ...

Sustainability Tensions in Supply Chains: A Case Study of Paradoxes and Their Management
(2018-02-06)
The comprehensive coverage of sustainability issues in a supply chain incurs goal conflicts—i.e., sustainability tensions—and is often limited by market characteristics, such as the availability of sustainable materials and services. While the mainstream business is prioritizing economic goals, a number of entrepreneurs are trying to move forward to more sustainable business practices for their own company and their supply chain. Fairphone represents such a case in the electronics industry, which is openly communicating ...

Exploring the Supply-Demand-Discrepancy of Sustainable Financial Products in Germany from a Financial Advisor’s Point of View
(2018-03-23)
Although retail investors’ interest in sustainable investment is constantly increasing, German credit unions and co-operative banks offer few sustainable financial products. The purpose of the study is to explore the current gap between supply and demand of sustainable financial investments in German retail banking from a financial advisor’s point of view. We use qualitative analysis of interviews with financial advisors based on a Grounded Theory approach with the aim to identify the key causation in the cause-effect ...

The relevance of herders’ local ecological knowledge on coping with livestock losses during harsh winters in western Mongolia
(2018-01-29)
In many regions of the world, traditional and local ecological knowledge is still important today for coping with environmental challenges. This study explored the relevance of such knowledge for predicting and coping with harsh winter conditions (dzud) in a remote area of western Mongolia, where government support to disaster-affected herders is restricted by weak infrastructure. Structured face-to-face interviews were held in 50 households (HHs), addressing aspects of livestock possession and management as well as ...

The ‘forma specialis’ issue in Fusarium: A case study in Fusarium solani f. sp. pisi
(2018-01-19)
The Fusarium solani species complex (FSSC) has been studied intensively but its association with legumes, particularly under European agro-climatic conditions, is still poorly understood. In the present study, we investigated phylogenetic relationships and aggressiveness of 79 isolates of the FSSC collected from pea, subterranean clover, white clover and winter vetch grown under diverse agro-climatic and soil conditions within Temperate and Mediterranean Europe. The isolates were characterized by sequencing tef1 and ...
