依靠科技进步 发展低碳农业

在全球携手应对气候变暖、减少温室气体排放的背景下,发展低碳经济是解决气候变化与经济发展矛盾的有效途径。通过描述气候变化、固碳减排对粮食安全、土壤碳汇、森林固碳、资源循环利用等影响和促进作用,深入分析发展低碳经济与可持续发展的关系,探讨如何在农业领域内开发高效循环生产体系,从而实现农业生产过程的固碳减排目的。由此,提出发展低碳农业是实现低碳经济的目标之一,它是一个复合技术体系,涉及了绿色农业、循环农业、生态文明、可持续发展理念。必须通过科学技术的突破,改造、提升低碳农业技术,改变农业现有的＂高能耗、高污染＂的生产状况,实现低碳生产、生活方式的转变。最后提出发展现代的低碳农业产业经济的对策和思考。     

Challenges to interdisciplinary research in ecosystem-based management

Despite its necessity, integration of natural and social sciences to inform conservation efforts has been difficult. We examined the views of 63 scientists and practitioners involved in marine management in Mexico's Gulf of California, the central California coast, and the western Pacific on the challenges associated with integrating social science into research efforts that support ecosystem-based management (EBM) in marine systems. We used a semistructured interview format. Questions focused on how EBM was developed for these sites and how contextual factors affected its development and outcomes. Many of the traditional challenges linked with interdisciplinary research were present in the EBM projects we studied. However, a number of contextual elements affected how mandates to include social science were interpreted and implemented as well as how easily challenges could be addressed. For example, a common challenge is that conservation organizations are often dominated by natural scientists, but for some projects it was easier to address this imbalance than for others. We also found that the management and institutional histories that came before EBM in specific cases were important features of local context. Because challenges differed among cases, we believe resolving challenges to interdisciplinary research should be context specific.     

Evolution of working conditions under the impact of ICTs

IntroductionInformation and communication technologies (ICTs) play a major role in the current evolution of work. They are both a great tool for emancipating human beings from the most tedious and most dangerous tasks and an effective vector for intensifying work.MethodsOn the basis of three foresight exercises carried out in recent years and by describing concrete examples of work organizations, the authors highlight the main possible trends for the changes to come.ConclusionsThey conclude on a few general principles that could allow the establishment of a win–win policy.     

Regional Research Capacity-Building in Sustainability Science: Facts,Gaps, and Futures in Northeast Asia

Abstract

Evidence shows that some conceptual ideas relevant to both local and global sustainability have been adopted in some official documents in northeast Asian nations, particularly China, South Korea, and Japan. This seems to be a very positive signal for the future development of sustainability science in this region. However, studyes show that there are still some major gaps there. One is the problem of how to build up the regional research capacity of sustainability science among northeast Asian research institutes across different disciplines as well as different political systems. Another is how to shift the conceptual frameworks of sustainability science into the operational policy frameworks. There are four major obstacles to the enhancement of regional research capacity-building in sustainability science. In order to build up the regional research capacity in sustainability science and to realize both local and global goals of the sustainable development in northeast Asia, this paper proposes some basic frameworks, including regional institutional innovations, establishment of a regional sustainability information network, initiatives of the regional assessment programme, and focus on the regional education and training of sustainability knowledge.     

Exploration of Science Parks

Abstract

Science parks have developed greatly in the world, whereas empirical researches have showed that science parks based on linear model cannot guarantee the creation of innovation. Hi-tech innovation is derived from flow and management of information. The commercial and social interactions between in-parks and off-park firms and research institutions act as the key determinant for innovation. Industrial clustering is the rational choice for further developing Chinese science parks and solving some problems such as the lack of clear major industries and strong innovation sense, etc.     

Cross-Platform Framing and Cross-Cultural Adaptation: Examining Elephant Conservation in Thailand

This case study investigates cross-platform framing process and framing alignment strategies of the world famous elephant conservation NGO. It examines how the intercultural adaptation facilitates the frame transformation against entrenched domesticated elephant traditions in Thailand. Besides web observation, this study conducted two field trips to interview the NGO staff and conservation experts, and observed human–elephant interaction. Enhancing the understanding of ecotourism, this study expands the framing theory by incorporating cross-platform and cross-cultural adaptation factors and provides insights of an effective Asian ecotourism model which transcends cultural differences and overcomes resistance by disseminating culturally sensitive and integrated framing strategies through various communication channels.     

Imagining Postscience: Heidegger and Development Communication

Modernization, the dominant contemporary model of development, has technoscientific rationality as its base. Alternatively, development can be understood as the ascent of individuals and communities toward their own conceptions of the good life. Such an understanding of development, it is argued, cannot be communicated under technoscientific assumptions. Instead, under the light of Heidegger's critique of technoscience and his philosophy of communication, a postscientific perspective is invoked for communicating development as good life, less violent to human communities and the environment, and less monolithic in design. Postscience evokes the multiplicity of ways in which we seek credibility for our projects in opposition to the monistic conception of truth and meaning in the technoscientific paradigm. Exploiting Heidegger's understanding of the world-disclosive power of language, development communication is understood as disclosing the genuine possibilities for the good life, concealed in a people's world, in an authentic act of engagement between the people and the communicator of development.     

Mountains and Handrails: Risk,Meaning, and Responsibility in Three National Parks

Where we live, the relationships we maintain, or the experiences we have can tell us about the way we perceive risk and the responsibility for its management. Perceptions of risk and responsibility are particularly relevant in US national parks, where unintentional injury is prevalent, yet support exists for allowing risk exposure. If experiencing risk may be both desirable (e.g., self-affirming) and undesirable (e.g., injury-causing), what is its role in a national park? Moreover, what are the expectations for visitors to encounter or to avoid it? In-depth interviews with National Park Service employees suggest that desired risk is contingent upon the circumstances in which it is encountered, and the values and prior experience of individuals. Employees perceive visitors as responsible for avoiding undesirable risk through information seeking and awareness, but also recognize considerable barriers to doing so. Theoretical and practical implications and avenues for future research are presented.
