This issue of PLoS Genetics contains the second of two important papers describing the high levels of meiotic failure caused by exposure of female mice to a chemical known as Bisphenol A (BPA) [1]. In the first article [2], Pat Hunt and her collaborators demonstrated high levels of meiotic failure in females exposed to BPA, suggesting that BPA exposure affects maturing oocytes. This conclusion ...
Population growth and climate change challenge our food and farming systems and provide arguments for an increased intensification of agriculture. A promising option is eco-functional intensification through organic farming, an approach based on using and enhancing internal natural resources and processes to secure and improve agricultural productivity, while minimizing negative environmental i...
The management of hydrologic catchments typically faces the challenge of keeping a reasonable balance between water quality demands and farming restrictions. In order to handle this problem it is most important to identify farming areas whose land use have a high influence on the nutrient leaching into the receiving stream. This identification can be regarded as a sensitivity analysis (SA). Cha...
Anecdotal evidence suggests that care farming practices have the potential to provide positive outcomes for young people in foster-care and residential care environments. A systematic review (searching; CINAHL, Web of Knowledge, PsychInfo) was conducted to explore how participation in care farming initiatives impacts attachment in children in foster-care and what aspects of care farming initiat...
Vegetable production constitutes an important sub-sector of the agricultural economy of KwaZulu-Natal. Most vegetables are cultivated in mixed-cropping types of farming systems. The technical efficiency of vegetable based cropping systems was estimated in order to identify the potential increase in production without incurring additional costs. The factors affecting technical efficiency and con...
We investigated aquaculture production of Asian tiger shrimp, whiteleg shrimp, giant river prawn, tilapia, and pangasius catfish in Bangladesh, China, Thailand, and Vietnam by using life cycle assessments (LCAs), with the purpose of evaluating the comparative eco-efficiency of producing different aquatic food products. Our starting hypothesis was that different production systems are associated...
This study was conducted with the objective of testing the hypothesis that tomato fruits from organic farming accumulate more nutritional compounds, such as phenolics and vitamin C as a consequence of the stressing conditions associated with farming system. Growth was reduced in fruits from organic farming while titratable acidity, the soluble solids content and the concentrations in vitamin C ...
Background: The study examined the impact of a contract farming scheme on the farmers’ income, food security, and nutrition. Methods: Simple random sampling was used to select 100 respondents for the study. Data were analyzed using descriptive and inferential statistics as well the Propensity Score Matching technique. Results: The major determinants of participation in contract farming included...
Drawing on interviews in Switzerland and New Zealand, we explore the concept of autonomy as part of a farming self. The farming self encompasses the dialectical relationship of autonomy as both value and tool that help us understand farmers within a wider set of economic, environmental and interpersonal relations. Farmers describe autonomy as a value in three related but slightly different ways...
