In recent years, churches across the world have become involved in dialogue on the theory and practice of sustainable development. A number of Western churches have expressed their concern about climate change and destructive living patterns, stressing the need for human beings to exercise the care for all creation based on a life of sharing and sacrifice. Some Orthodox churches, however, quite recently included the environmental issues in their agendas. While the Bases of Social Concept, a major doctrine of the Russian Orthodox Church adopted in 2000, for the first time emphasises the Churchs position in overcoming environmental crisis and presents a solid basis on which to build the future environmental strategy of the Church, the Ethiopian Orthodox Church has not yet drawn up a programme document that might serve as a framework for the Churchs current extensive activities in the field of biodiversity conservation and sustainable forestry practices. Hence, despite certain closeness of both institutions, there is the potential for strengthening their roles in promoting sustainable development, based on the Biblical concept that the Earth belongs to the Lord and humans are responsible stewards assigned the duty to work for creation and care for it. This paper seeks to demonstrate by means of comparable analysis between the two Churches, Orthodox in nature but different in rites and religious practices, that traditional, highly conservative faiths may serve as powerful instruments of spreading out the ideas of sustainable development as the basis of spiritual revival in the situation of the two concurrent and interrelated crises – spiritual and ecological.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue. 相似文献

Walker P 《Disasters》2005,29(4):323-336
This paper reflects on the genesis of the Code of Conduct for the International Red Cross and Red Crescent Movement and Non-Governmental Organizations (NGOs) in Disaster Relief, on the tenth anniversary of its adoption. The origins, usage and future of the code are examined with respect to three debates, current at the time of its inception, namely: the debate about the core content of humanitarianism; the debate about coherence and the consensual nature of the humanitarian community; and the debate about the need for, and the ability to demonstrate, accountability. The paper concludes that although the Code of Conduct was very much a product of its time, its content remains relevant today. However, its future application hinges on the capacity of those who purport to follow it to realise true accountability, and on proving that the code, written essentially for natural disasters, is relevant to contemporary complex emergencies. 相似文献

Public Participation and Effective Water Governance at the Local Level: A Case Study from a Small Under-Developed Area in Chile 总被引:1,自引:0,他引:1
Tarisai?Garande Suzan?DaggEmail author 《Environment, Development and Sustainability》2005,7(4):417-431
The concept of participation in rural development has been evolutionary for the past two decades with those involved, such
as development agencies and governments, particularly in rural water supply, re-evaluating their active role. The move towards
effective community participation has encouraged a shift from the traditional top-down to a bottom-up approach whereby there
is a decentralisation of unevenly distributed resources and power to empower a community and allow mobility of ‘people participation’.
The Molinos water project is the first large-scale development project of its kind introduced into the village of Molinos
in an under-developed area of Chile, where there has been no tradition of people participation. The project objective was
to implement a low technology, low budget water treatment plant to the village of Molinos. Various aspects have hindered the
continued development of the project including both technical and financial. In terms of people participation, the initial
approach used was the top-down approach. There was a failure to fully integrate the community or inform the community in a
formal manner about the project and consult them regarding key project issues. This case study illustrates that the lack of
comprehensive consultation and the low level of participation of the community on the participatory scale does not achieve
much in terms of people-centred benefits. For governance at the local level to be effective, participation should be inclusive and communicative so as to
enhance transparency throughout the project lifetime.
