可持续发展的理论与宏观调控模式 总被引:8,自引:0,他引:8
从可持续发展观和可持续发展战略出发,分析了传统发展观和发展模式的特点及其主要弊端;进而根据有关国际性文件中的可持续发展概念,给出了中国人易于理解的描述及其基本内涵,强调了人与自然和谐、发展与资源环境相协调是可持续发展的核心,并结合实例阐明了协同学理论是可持续发展的基本理论依据;在分析发展与资源环境相协调的基础条件之后,重点论述了它们之间的协调机制,提出了可持续发展的宏观调控模式。 相似文献

This article critically reviews the evolution of urban environmental management in Shanghai since 1978. Established in a transitional
postsocialist economy and shaped by a spectacular urban redevelopment process, the current environmental management framework
of Shanghai has succeeded in mitigating major industrial pollution and improving urban amenities with unprecedented pace and
magnitude. However, it generally failed to take social equity and environmental justice issues into consideration. Based on
Haughton’s models of sustainable urban development, this article proposes four priorities and five principles within the framework
of a fair shares cities model for the future environmental management of Shanghai and briefly discusses their policy implications
and implementation issues. The authors argue that Haughton’s approach is relevant to Shanghai’s case because the essence of
his argument—the multidimensional equity principles—is the core of the concept of sustainable development. 相似文献

The promising spread of sustainable agriculture in Asia 总被引:1,自引:0,他引:1
Despite great successes in increasing food production, Asia still faces enormous food security challenges. Most commentators agree that there will have to be increases in food production from existing agricultural land, but many are pessimistic about the future, judging likelihood of success on the basis of past performance of 'modern' agricultural development. Sustainable agriculture, though, offers entirely new opportunities, by emphasising the productive values of natural, social and human capital, all assets that Asian countries either have in abundance or that can be regenerated at relatively low financial cost.
This paper sets out an assets-based model of agricultural systems, together with a typology of eight approaches for sustainable agriculture improvements. In the 16 projects/initiatives spread across eight countries that are analysed, some 2.86 million households have substantially improved total food production on 4.93 million hectares, resulting in greatly improved household food security. Proportional yield increases are greatest in rainfed systems, but irrigated systems have seen small cereal yield increases combined with added production from additional productive system components (such as fish in rice, vegetables on dykes). The additional positive impacts on natural, social and human capital are also helping to build the assets base so as to sustain these improvements in the future.
This analysis indicates that sustainable agriculture can deliver large increases in food production in Asia. But spreading these to much larger numbers of farm households will not be easy. It will require fundamental policy reform. 相似文献

城市可持续发展及其在我国的现状 总被引:3,自引:0,他引:3
城市可持续发展是一个值得研究的问题。它是指城市的发展必须满足目前的需要又满足未来的需要。城市可持续发展包括经济、社会、环境、资源和技术的可持续发展。中国的城市在可持续发展方面存在着许多问题,如环境污染严重。所以我们必须立即采取措施来改变这种局面。 相似文献

With 20% of the world’s forests, Russia has global potential in bioeconomy development, biodiversity conservation and climate change mitigation. However, unsustainable forest management based on ‘wood mining’ reduces this potential. Based on document analysis, participant observations and interviews, this article shows how non-state actors—environmental NGOs and forest companies—address forest resource depletion and primary forest loss in Russia. We analyse two key interrelated forest discourses driven by non-state actors in Russia: (1) intensive forest management in secondary forests as a pathway towards sustained yield and primary forest conservation; (2) intact forest landscapes as a priority in primary forest conservation. We illustrate how these discourses have been integrated into policy debates, institutions and practices and discuss their relation to relevant global discourses. The article concludes that despite successful cases in conserving intact forest landscapes, there is still a frontier between sustainable forest management discourses and forestry practice in Russia.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01643-6. 相似文献
