Interdisciplinarity and Responsibility for Land Use, GIS and Eco-systems: Some problems of social traps

Interdisciplinary studies and cooperations are necessary for practical work as well as studies in geodesy. Responsibility is a function of power, impact and knowledge. The more strategically central one’s position is in terms of power, influence and knowledge, the higher one’s responsibility is. This is an idea which can be worked out in more detail by using interdisciplinary approaches and distributive models on different levels. Social traps, Prisoners’ Dilemma situations, etc, as pertaining to land, soil, and environment as well as some examples from geodesics and the study of the usage of nature systems like lakes and flood plain areas are discussed regarding responsibility and distribution problems.“Naturalists’ Dilemmas”(or “Enjoyers’ Dilemmas”) are sketched and potentially solved by proposing a viable distribution strategy.

Responsibility for Eco-systems and problems of social traps and dilemmas

Responsibility is a function of power, impact and knowledge. The more strategically central one’s position is in terms of power, influence and knowledge, the higher his or her responsibility would be. This is an idea which can be worked out in more detail by using distributive models of graph theory and predistribution assignments of rights and duties according to different levels.

Corollary of Marine Eco-system Sustainability by Addressing the Issues of Bycatches

The issue of bycatch in the fisheries sector has been a major concern for the marine biologists over few decades in terms of conservation of marine eco-system and sustainability of the fisheries sector and marine biodiversity.As far as the concept of Bycatch is concerned,these are the unwanted species having less commercial importance,which in most of the cases disposed into the seas onboard or are caught during fishing.The article discusses the social,economic,cultural,and environmental impacts in addressing the issue of bycatch.The concern regarding bycatch is relatively new in the horizon in Indian perspective though it is often considered a major issue faced by developed nations since long.The problem of bycatch poses a serious threat to livelihoods and food security as it acts as a precursor to depletion of the food sources for local consumption with adverse social,economic,cultural,and environmental impacts.The adverse effects of by-catch can be mitigated through commercialisation of bycatch and making profits from the sale of bycatch,opening up of new markets for bycatch species or products,uses of bycatch as fishmeal and application of bycatch reduction devices(BRDs).Reorientation of the present monitoring system to collect fisheries data,strengthening technical know-how,bringing effective policy intervention,efficient co-management,and sincere and honest efforts in reducing bycatch and discards may provide a considerable impact towards sustainability of marine eco-system.

由表及里的苏州市生态城市建设评价(英文)

After the discussion of accomplishments of ecological urban construction in Suzhou City, the current ecological urban construction in Suzhou has been compared with the national standard for ecological urban construction. According to the actual situation of Suzhou urban construction, the health evaluation index system and standards for urban eco-system have been established based on natural, economic and social sub-system. By using mean square deviation, indexes' weights have been identified. After the quantitative research on the health condition of urban eco-system in Suzhou City from 2004 to 2008, it has found key problems existing in its ecological urban construction. The results show that Suzhou urban eco-system develops well in general, but the three sub-systems are coordinated with each other moderately, and natural sub-system suffers severe pressure.

Promising thermal photonic management materials for sustainable human habitat

The spectral characteristics of outdoor structures,such as automobiles,buildings,and clothing,determine their energy interaction with the environment,from broad-spectrum absorption of light energy to high-efficiency thermal emission.Recently developed spectrally selective absorption(SSA)materials permit the reduction of energy loss from human habitat eco-system in the sustainable way and further reduce the utilization of fossil energy to achieve carbon neutrality.Here we review recent advances in SSA materials that enable rational and efficient management of thermal energy and provide new solutions for the resource base that supports human life like comfortable heat management,electricity production,and water supply.The basic principles of thermal photonic management,the regulation of SSA materials,and functional properties are summarized.An outlook discussing challenges and opportunities in SSA material energy management for comfortable living environments is finally presented,which expects the enormous potential of this interdisciplinary research in solving growing resource-shortage of human society.
