The relationship between agriculture and nature is a central issue in the current agricultural debate. Organic Farming has
ambitions and a special potential in relation to nature. Consideration for nature is part of the guiding principals of organic
farming and many organic farmers are committed to protecting natural qualities. However, the issue of nature, landscape, and
land use is not straightforward. Nature is an ambiguous concept that involves multiple interests and actors reaching far beyond
farmers. The Danish research project Nature Quality in Organic Farming has investigated the relationship between nature and organic farming. This article will focus on an expert workshop held
in connection with the project that investigates the way different actors conceptualize nature. Farmers, scientists, and non-governmental
organizations came together to discuss their experiences of nature and expectations of organic agriculture. From this interaction,
it was clear that nature is a contested notion. Different understandings of nature exist within the three groups and there
is disagreement as to whether emphasis should be given to biological qualities, production values, or experiential and aesthetic
perspectives. This complexity provides a challenge to organic farming as well as to the implementation of nature considerations
in general. It illustrates an underlying battle for the right to define nature and nature quality and essentially decide what
organic farmers should work towards. We argue that successful implementation requires organic farmers to carefully consider
what expectations they wish to meet. Optimally it is dependent on a dialog between stakeholder interest groups that allows
for multivocality and pluralism. 相似文献

The EEC directive on ‘Major Accident Hazards of Certain Industrial Activities’ has been implemented in Denmark. This means that risk analyses of some activities must be made before July 1989. One of the first plants that was analysed was a warehouse for the mixing, repackaging and distribution of organic chemicals. The analysis was performed as a commercial contract by Risø National Laboratory. The report has been submitted to the authorities but the plant has not yet been approved due to submission of a large amount of analyses of other plants. This paper illustrates how a risk analysis of a chemical plant can be made. 相似文献

Synthetic musk compounds used in detergents and cosmetics include nitro and polycyclic musk compounds. These compounds are discharged after use via domestic wastewater and sewage treatment plants to the aquatic environment. Quantitative detection of nitro musk and polycyclic musk compounds by GC/HRMS in Danish farmed trout and human milk from primiparous mothers are reported. The polycyclic musk, HHCB, dominated the synthetic musk compounds found in trout samples from 1999 with a median concentration of 5.0microg/kg fresh weight (n.d.-52.6microg/kg fresh weight) and in trout samples collected in 2003 and 2004 with a median concentration of 1.2microg/kg fresh weight (n.d.-28.0microg/kg fresh weight). It was also found that the concentration of musk xylene in trout sampled at the same fish farms decreased considerably from a median concentration of 5.1microg/kg fresh weight in 1992 to a median of 0.5microg/kg fresh weight in 1999 and to a median less than the detection limit (0.23microg/kg fresh weight) in 2003. HHCB also dominated in Danish human milk samples collected in 1999 with a median concentration of 147microg/kg fat (38.0-422microg/kg fat). Human dietary intake assessment and body burden calculations on data from 1999 indicate that the main source of exposure to human cannot be attributed to the consumption of farmed trout. 相似文献

The main purpose of the present work is to study the concentration of atmospheric particles in the Candiota region, in the state of Rio Grande do Sul, where the Presidente Médici coal power plant is located. Aerosol samples were collected at the studied locations between December 2000 and December 2001 during 24 h periods at 15 day intervals using HV PM10 and dichotomous samplers. Then, the values obtained with the ISCST (Industrial Source Complex Term) model, with the HV PM10 sampler at all studied stations, and with the dichotomous sampler at the 8 de Agosto station were compared with each other. The results show that the values for the model had been underestimated in relation to the HV PM10 data for the studied stations, but agreed with the values obtained with the dichotomous sampler. 相似文献
