/ This study is concerned with the role that communication can play in facilitating the utilization of ecological information by different sectors of society involved in environmental decision-making. The ecological information system is used as a conceptual framework. This system is a model for the analysis of interactions between three sectors involved in the management of natural resources: researchers in ecology, change agents, and rural producers. Two case studies of organizations carrying out scientific research aimed at finding and implementing sustainable strategies of resource management were carried out. The purpose was to examine how real situations function in terms of communication strategies and to analyze such situations in relation to the model proposed. The analysis revealed the importance of promoting the feedback of information from change agents and rural producers to the research sector and the incorporation of this information into the research process. It also emphasized the relevance of having "active utilizer constituencies" within the rural producers who make demands upon the entire system in order to satisfy information needs. The creation of linkage systems facilitating the connection between the generation and utilization of information was supported. In particular, the establishment of special teams within research institutions is proposed, which could promote the links between the sectors through the use of communication as an instrument of work. 相似文献

The paper analyses the costs and benefits of conserving wildlife and reports part of a wider research project which aims to estimate the benefits of certain ecological types and habitats, and to compare the outcome of different techniques used to value wildlife. The authors outline a range of philosophical, technical and methodological problems in deriving cardinal measures of costs and benefits. 相似文献

ABSTRACT: This paper is a computer simulation analysis of an agricultural nonpoint pollution problem. Computer modeling is a universally applicable tool that can be used for establishing the linkages between and the quality of agricultural runoff in both surface and subsurface flow. The tradeoffs between the costs of soil conservation practices and water quality are reported, and the economic implications of such tradeoffs are discussed. Soil and nutrient losses resulting from crop production practices are analyzed using a field-scale computer simulation model (CREAMS). No-till planting, reduced tillage, and sod waterway systems are more cost effective than other practices for controlling soil and nutrient runoff losses. Nitrate leaching losses are increased slightly by most soil conservation practices. Terrace systems and permanent vegetative cover impose the greatest societal cost for water quality protection. Public cost sharing and tax incentives encourage farmers to adopt expensive structural practices, and policies are needed to get cost-effective practices implemented on critical acreage. Extensive treatment of land is necessary for agricultural best management practices (BMPs) to significantly improve water quality in areas that are intensively farmed. 相似文献

This paper is a revised version of one presented to the Regional Science Association Conference, University of Leeds, September 1983.
The extent of rural poverty is largely hidden, yet mean rural incomes are lower than in urban areas. Equally, the differential between low incomes and high minimum house prices in rural areas not always acknowledged. This paper looks at the planning response to these problems against alternative approaches including discriminatory policies against second home owners in rural areas. The paper concludes by identifying a solution restricting private development and augmenting public‐sector provision in rural areas. 相似文献

Flood warning systems offer a large potential for reducing human losses and property damage in flood-prone regions. This article illustrates why official organized systems should not be relied on completely in either developing or developed societies. It then discusses an indigenous flood warning system in a rural area of Eastern India, its value, and its importance in providing an alternative means of detecting, interpreting, and relaying flood warning information to the ultimate users of this information, i.e., those populations most at risk from floods.The National Center for Atmospheric Research is operated by the University Corporation for Atmospheric Research and is sponsored by the National Science Foundation. 相似文献

The Planning Inquiry is used in Britain as a vehicle for resolving conflicts between energy developments and land use in areas of high ecological or amenity value. This is a report of one such inquiry; the Lyndhurst Inquiry which has been regarded as a test case of establishing oil and gas reserves against the importance of environmentally sensitive areas. The ultimate decision is seen as indicative of the complexity of issues involved. 相似文献

Bovine spongiform encephalopathy (BSE) has been documented in 28 countries and adversely affected farmers and rural communities
around the world. Our study examines the impacts of and adaptive responses of producers to BSE in western Canada. Moreover,
it explores the role that holistic management (HM), and its combined focus on environmental, social, and economic sustainability,
might play in mitigating the effects of BSE. One survey was sent to 835 HM producers and another to 9,740 producers across
Manitoba, Saskatchewan, and Alberta. The disease, and concomitant climate change and low commodity prices, had devastating
impacts on both groups. Yet, HM producers were much more optimistic about their ability to adapt to BSE and the future of
agriculture than their non-HM counterparts. Social networks, namely HM clubs and the larger HM community, enabled these producers
to mitigate the impacts of BSE. Agronomic responses, especially those associated with rotational grazing and increases in
on-farm biodiversity were also important. That HM has been such an effective adaptive response to BSE indicates the importance
of this and other grassroots responses to rural crises, whether they be associated with zoonotic diseases or indeed environmental
change as a whole. 相似文献
