Asia is an area filled with vigor and vitality and also conflicts, an area that "takes pride in its rich cultures, religions and diversity."More and more statesmen and scholars are watching closely the human rights conditions in the changing Asia. Asia is no longer a concept in its economic, cultural and geographical sense. It has become a regional community that has had an important impact on the human rights development in the world. In the 21 st century filled with challenges and hopes, people want to see not only an economically prosperous Asia but also an Asia community with increasing humanistic spirit and pursuit for constitutionalist values. 展开更多

In general, China's development is not sustainable because its ecological footprint is beyond its bio-capacity. The sustainability status of each pr ovince in China is presented. Ulanowicz's development capacity formula w as introduced to discuss the relationship of development and ecological footprin t's diversity. The diversity of ecological impacts is related to the e fficiency with which an economy uses the source and sink services of the environment and, in this view, should be a factor in economic output. Developme nt capacity, calculated from the ecological footprint and its diversity , is used to examine the relationship of economic output with the st ructure of the ecological footprint. China and its provinces are prese nted as a case study to investigate this relationship. The analysis s hows that footprint capacity is significant in predicting economic outp ut. Increasing the ecological footprint's diversity is presented as another way to increase development capacity. 展开更多

The purpose of this study was to classify current forest cover types,and to investigate stand development patterns for natural forests in six areas in northern Baekdudaegan,South Korea.Twenty-eight independent forest communities were aggregated into eight forest cover types by species composition in the overstory of each forest community.The forest cover types were of mixed mesophytic,‘‘others’ ’ deciduous,Quercus mongolica dominant,Q.mongolica pure,Pinus densiflora–Q.mongolica,P.densiflora,Betula ermanii,and Q.mongolica–P.koraiensis.The ecological information was organized by importance value and species diversity for each forest type.Based on the correlation between species diversity index and the abundance of Q.mongolica plus P.densiflora for corresponding forest cover types,we compared the developmental process and approximate successional pathway between each cover type.The P.densiflora forest cover type changes into the P.densiflora–Q.mongolica cover type,followed by the Q.mongolica dominant cover type through continuous invasion of the oak trees.Furthermore,the Q.mongolica pure cover type would spread toward the Q.mongolica dominant cover type with a mixture of various deciduous tree species.The Q.mongolica dominant cover type progresses through the other deciduous cover types to the mixed mesophytic cover type with diversified composition and structure.On the mid to lower slopes,with loamy soils and good moisture conditions,various deciduous forest types should progress,by ecological succession,toward the mixed mesophytic cover type without any further disturbance. 展开更多

[ Objective ] The aim was to explore the relation between culture diversity and biodiversity of the Zhuang people. [ Method ] Botany in minority ethnic groups was researched based on information searching, interviewing and surveying with consideration of the importance of cultural and biological diversity. [ Result] The Zhuang culture, involving color, cuisine, geography and song, is closely related to biodiversity, and worship culture, involving plants, animals, and folk cus- tom, plays an important role in protection of biodiversity. However, biodiversity is significantly affected by some factors, including natural condition, population quality, traditional culture, wrong policies, negative effect of modern ecological culture, natural and environmental resources. [ Conclusion] It is suggested that lo- cal education should be enhanced to absorb modem science&technology, to promote the concept of confirming to nature and of harmonious development and to achieve sustainable development in western of Guangxi. 展开更多

The 1998 Conference of Parties to the Convention on Biological Diversity asked national governments to demonstrate the importance of biological diversity in supporting rural communities. This paper introduces‘agrodiversity’as the primary way in which farmers use biological diversity and, more generally, the natural diversity of the environment for production, including their choice of crops, and management of land, water and biota as a whole. Promoting agrodiversity and understanding how it functions in tropical smallholder farming systems is the best way that importance may be shown. A win-win scenario is presented which links agrodiversity to land degradation control and sustainable rural livelihoods as evidenced by food security. It is argued that policies that encourage biological diversity in areas of land use will not only meet countries’ responsibilities under the Convention but will also address land degradation problems and support to rural livelihoods. The human significance of various types of biological diversity is shown. Sustainable rural livelihoods are presented in the new capital assets framework to demonstrate how rural households may use various components to control land degradation. To enable agrodiversity to be implemented practically, it has been codified into core elements of: biophysical diversity, the diversity of the natural environment that controls the resource base for food production; management diversity that embraces the practices (many of them indigenous) of farmers such as live hedges, soil amendments and ridge tillage techniques; agro-biodiversity which is the diversity of crop, plant and animal combinations; and organisational diversity, the way that farms are owned and operated, and the way that capital assets are allocated. Each element is then systematically related to show how agrodiversity controls land degradation and how it promotes food security. The example of the maize-Mucuna system in South America is cited as an evident demonstration of the value of agrodiversity to both soil conservation and to smallholder farmers’ livelihoods. 展开更多

In the framework of biodiversity's studies of animal's genetic resources in general and especially camels, the authors focused, in the case of biodiversity, on the phenotypic and genetic variability of each camel populations studied in southwestern of Algeria. The objective of the present study is to describe the conditions of dromedaries breeding, to analyze their phenotypic diversity, redefine the range flocks, highlight the perspectives of exploitation and use their products in livestock systems sustainablely. Knowing that the camel occupies a vital place in the socioeconomic development of breeders, owing to the multiple functions and services it provides. However, the pressures of diverse origins including population growth and recurrent droughts take serious threats to the development of the species. This survey was conducted during 2 years over 2500 animals owned by 60 farmers were studied. These animals were analyzed in terms of phenotypic and ethno-geographical evolution of breeding. A large number of blood samples (200) were collected, which allowed us to be the first DNA bank of camels in Algeria. 展开更多

Cultural diversity originates from modern cultural industries. The UN's decade–long promotion of cultural diversity coincides with the advancement of China's cultural and creative industries; however, China's situation is different from the creative economy advocated by the UN in terms of developmental logic. The policy of cultural diversity provides a basis for the UN to push forward the development of cultural and creative industries in developing countries. It is derived from the developmental theories of developed countries, which regard creativity(innovation) as a "technique" and overlook its uniqueness. The digital revolution has never given fair play to developing countries which explains why the UN's promotion of cultural diversity has not yet helped developing countries to substantially increase their exports of cultural goods and services in the past ten years. Nevertheless, the development of the in ternet and digital technology may create an opportunity for developing countries to catch up with and surpass their developed neighbors. China's unique approach to cultural and creative development may serve as a model for the international community to pursue sustainable development in the future. 展开更多

Our paper presents an interactive four-dimensional model for studying the long- and short-term development of the communication discipline with Israel serving as a case study: institutional-contextual, institutional-in-field, intellectual-contextual, and intellectual-in-field. Our empirical analysis utilized personal interviews, archive documents, and statistical data. Four main processes were discerned: transition from integration to alienation between institutions of higher learning and the larger political and ideological context; a shift from Hebrew University Institute of Communication's institutional monopoly to a multiplicity of increasingly competitive communication schools/departments; transition from intellectual hegemony to limited intellectual diversity; and gradually improving status for the communication field among social science disciplines. Our case-study analysis validated the interactive relationship among the model's conceptual dimensions, calling for future cross-national comparisons. 展开更多

U-S合作是教师专业发展的重要举措。审视U-S合作的历程可知,U-S合作致力于多方位促进教师专业发展,协同逐渐成为U-S合作促进教师专业发展的底层逻辑。随着合作的持续推进,这一底层逻辑在促进教师专业发展方面所潜在的矛盾也逐渐暴露出来。一方面,大学与中小学的文化差异阻碍了协同的深度发生;另一方面,为了实现大学与中小学的协同,双方不得不做出诸多的妥协,在妥协的语境下,中小学教师往往面临着主体性丧失的风险。与之相对,在求异这一核心理念的引领下,跨界学习旗帜鲜明地提出了“差异即资源”的主张,并通过互动场域的营造和互动系统的建构,为“差异即资源”提供了现实可能,也为优化U-S合作提供了新的思路。 展开更多
