/ With over 2500 Australian Landcare groups, 65,000 volunteer members, and considerable evidence of program impact, Landcare is an important example of state-sponsored rural development in a developed nation. The agency-community partnership is a fundamental element of Landcare and getting the partnership right is vital to long-term program success. After reviewing the emergence of Landcare in the state of Victoria, the author reports research from a 1995 survey of Victorian Landcare groups. Survey information highlighted the extent of agency-group contact, the important roles agency staff played in many Landcare groups, and the positive impact of agency contact and government funding upon group activity. Large majorities of groups reported they were satisfied with their relationship with agency staff. However, a majority of groups reported money or materials provided to manage land and water degradation was inadequate. Recently proposed changes to the Landcare program will provide government funding of work on private property and may address this concern. A majority of groups also reported support for leadership and management training was inadequate and respondents emphasized the need to revise program guidelines that limit funding for group coordinators. This information highlighted the importance of articulating a practical model of community participation in Australia and adopting a systematic approach to providing agency support for Landcare groups. Reflecting upon the Landcare experience, the author suggests some of the key elements of a practical model of state-sponsored citizen resource management contributing to rural development.KEY WORDS: Landcare; Australia; Community participation; Rural development; Citizen resource management; Sustainable agriculture 相似文献

One of the most important elements behind the success of Community‐based Therapeutic Care (CTC) programmes for the treatment of severe acute malnutrition has been their ability to achieve high levels of coverage. In CTC, coverage is measured using the Centric System Area Sampling (CSAS) method, which provides accurate and reliable estimates of programme coverage as well as information on the primary reasons for non‐attendance. Another important feature of CTC programmes is their use of socio‐cultural assessments to determine potential barriers to access and to develop context‐specific responses. By analysing data on non‐attendance provided by CSAS surveys, in conjunction with data from socio‐cultural assessments, it is possible to identify common factors responsible for failures in programme coverage. This paper focuses on an analysis of data from 12 CTC programmes across five African countries. It pinpoints three common factors (distance to sites, community awareness of the programme, and the way in which rejections are handled at the sites) that, together, account for approximately 75 per cent of non‐attendance. 相似文献

Soil acidification was assessed in the Eastern Sudetes Mountains (Czech Republic) between 1941 and 2003, i.e. before and after the period of major industrial pollution (1950s-1990s). The twenty sites included in our study were distributed along a gradient of altitude ranging 1000 m. Values of pH have decreased in 80-90% of the pairs of samples after the six decades, on average by 0.7 for pH-H2O and 0.6 for pH-KCl. Organic matter increased in the topsoil, probably reflecting a change in decomposition conditions. The most important finding is that the acidification varies along the joint gradient of altitude/tree layer composition, and displays a changing pattern in three soil horizons (A, B and C). Contrary to expectations, most acidified were soils in beech forests at lower elevations. 相似文献

This study reports a general assessment of the organic composition of the PM2.5 samples collected in the city of Augsburg, Germany in a summer (August-September 2007) and a winter (February-March 2008) campaign of 36 and 30 days, respectively. The samples were directly submitted to in-situ derivatisation thermal desorption gas chromatography coupled with time of flight mass spectrometry (IDTD-GC-TOFMS) to simultaneously determine the concentrations of many classes of molecular markers, such as n-alkanes, iso- and anteiso-alkanes, polycyclic aromatic hydrocarbons (PAHs), oxidized PAHs, n-alkanoic acids, alcohols, saccharides and others.The PCA analysis of the data identified the contributions of three emission sources, i.e., combustion sources, including fossil fuel emissions and biomass burning, vegetative detritus, and oxidized PAHs. The PM chemical composition shows seasonal trend: winter is characterized by high contribution of petroleum/wood combustion while the vegetative component and atmospheric photochemical reactions are predominant in the hot season. 相似文献

Mining-contaminated sites and the affected communities at risk are important issues on the agenda of both researchers and
policy makers, particularly in the former communist block countries in Eastern Europe. Integrated analyses and expert based
assessments concerning mining affected areas are important in providing solid policy guidelines for environmental and social
risk management and mitigation. Based on a survey for 103 households conducted in a former mining site in the Certej Catchment
of the Apuseni Mountains, western Romania, this study assesses local communities’ perceptions on the quality of water in their
living area. Logistic regression was used to examine peoples’ perception on the quality of the main river water and of the
drinking water based on several predictors relating to social and economic conditions. The results from the perception analysis
were then compared with the measurements of heavy metal contamination of the main river and drinking water undertaken in the
same study area. The findings indicate that perception and measurement results for the water quality in the Certej Catchment
are convergent, suggesting an obvious risk that mining activities pose on the surface water. However, the perception on drinking
water quality was little predicted by the regression model and does not seem to be so much related to mining as to other explanatory
factors, such as special mineralogy of rock and soils or improper water treatment infrastructure, facts suggested by the measurements
of the contaminants. Discussion about the implications of these joint findings for risk mitigation policies completes this
article. 相似文献

As a result of Structural Adjustment Programme from the 1980s, many developing countries have experienced an increase in resource extraction activities by international and transnational corporations. The work reported here examines the perceived impacts of gold mining at the community level in the Wassa West District of Ghana, Africa and discusses those perceived impacts in the context of globalization processes and growing multinational corporate interest in Corporate Social Responsibility (CSR). Interview data compared community members' perceptions with those of company representatives in three communities. The results indicate that communities held companies responsible for a series of economic, social, and environmental changes. While recognizing some of the benefits brought by the mines, communities felt that the companies did not live up to their responsibility to support local development. Companies responded by denying, dismissing concerns, or shifting blame. Findings from this work show that lack of engagement and action by government agencies at all levels resulted in companies acting in a surrogate governmental capacity. In such situations, managing expectations is key to community-company relations. 相似文献

Interest in Community Benefits (CB) has increased over the past decade mainly due to the growing number of wind farms and related criticism. Because CB are a voluntary gesture by the developer, there is no standard practice or institutionalised approach for good governance of the benefits; every community has a different approach, tailored to local needs and depending on the stakeholders involved. Additionally, since CB are a rapidly emerging practice, little is known about their governance, what actors are involved and how affected communities participate in decision-making on renewable projects. Using the Farr wind farm in Scotland, one of the first to introduce CB, as a case study, this paper sheds light on the governance structures surrounding the set-up, management and allocation of funds. It also contributes to the emerging body of work regarding transparency and community participation in CB, and the extent to which these might facilitate a transition to a low-carbon future. 相似文献

We analyzed the management, resource use and conservation of the Ankarafantsika National Park (Madagascar) to develop a management plan, which provides a sustainable development strategy of the area while empowering the local residents. Using qualitative methodology we performed interviews with villagers and local organizations to assess the park’s successes and failures from local stakeholders’ perspectives. People living in a village with a permanent Madagascar National Parks (MNP) agent are more favorable to and supportive of the park conservation. People living in the park are supportive but are more divided. On the other hand, people living on the periphery of the park see conservation as more of a burden. Strategies like more equitable distribution of wealth, environment improvement and decentralization of power are discussed to achieve a more sustainable management plan based on community natural resources management. Short-term, medium, and long-term interventions from park authorities are needed to ensure the cooperation of local people in conservation endeavors. 相似文献

Contrary to the assumptions of many previous theoretical models, group size has recently been shown in experiments to have
an effect on the relative (as well as absolute) competitive abilities of group members. Here we introduce a novel and effective
mathematical tool for describing how relative competitive ability will change for any two specified individuals within a group
as group size changes. We show that there is no simple general rule for describing how relative competitive ability will change
with group size. A subsequent empirical test of the model helps to illustrate that very specific knowledge of the system under
study is needed in order to produce robust predictions.
