Poverty alleviation and social upliftment of rural India is closely linked with the availability and use of energy for development. At the same time, sustainable supply of clean and affordable renewable energy sources is required if development is to be sustainable, so that it does not cause any environmental problems. The purpose of this paper is to determine the key variables of renewable energy implementation for sustainable development, on which the top management should focus. In this paper, an interpretive structural modeling (ISM) - based approach has been employed to model the implementation variables of renewable energy for sustainable development. These variables have been categorized under ‘enablers’ that help to increase the implementation of renewable energy for sustainable development. A major finding of this research is that public awareness regarding renewable energy for sustainable development is a very significant enabler. In this paper, an interpretation of variables of renewable energy for sustainable development in terms of their driving and dependence powers has been examined. For better results, top management should focus on improving the high-driving power enablers such as leadership, strategic planning, public awareness, top management support, availability of finance, government support, and support from interest groups.

This paper marks the first in a series of studies into the potential use of pyrolysis products in the development of more sustainable practices within the agricultural industry. In this study, the immediate benefits of the application of biochar to crop yields of Raphanus sativus (radishes) are assessed. Furthermore, the study reports on the preliminary findings into the potential application of pyroligneous acid (wood vinegar) as a biocidal agent against crop disease. Although germination tests undertaken on biochar/compost blends of up to 1: 2, by weight, showed no significant adverse effect from the addition of the nutrient rich carbonaceous solid, evidence of substantial increases in crop yield through the addition of biochar were not observed. In sharp contrast, zones of inhibition were observed at 3-10 vol. % upon application of pyroligneous acid to two causal agents responsible for certain diseases in vegetable and fruit crops, i.e. Rhizobium radiobacter (agrobacterium tumefaciens) and Xanthomonas campestris, highlighting the versatility in the application of pyrolysis products and avenues for exploration in the development of this biomass conversion technology.

A vállalatok egyre gyakrabban alakítanak ki olyan kapcsolatokat, melyek célja az egymással, illetve más típusú szervezetekkel (pl. kormányzati vagy civil szervezetekkel) különféle célok érdekében megvalósuló együttműködés. Ezen együttműködési formák egy része kedvező hatással van a vállalatok környezeti, illetve társadalmi teljesítményére is, és ezáltal – a szűken vett profitérdekeken túl – elősegíti a fenntartható fejlődés társadalmi céljának megvalósítását is. Jelen cikk célja, hogy bemutassa a vállalati szférára jellemző együttműködési formákat magyarázó legfontosabb szervezetelméleti megközelítéseket, majd ezek tükrében ismertesse a fenntartható fejlődés ügyét is elősegítő együttműködési kapcsolatok korszerű megnyilvánulási formáit. _________ Corporations more and more often engage in relationships, which aim at cooperation with each other and other types of organisations (e.g. governmental or nongovernmental organisations). Some of these collaborative efforts have a positive impact on the environmental and social performance of participating organisations and thus – apart from their positive impact on profitability – also foster the implementation of sustainable economic and social development. The objective of this article is to introduce the most important organisational theories, which give an explanation of the cooperative efforts of the corporate sector and, using this as a basis, to provide an overview of the most up-to-date forms of cooperation, which enhance our chances in the direction of a sustainable future.

Along with the recognition of the increasing environmental and social problems stemming from globalization, the need to address these problems and to develop the relevant international framework has strengthened since the 1970s. The scope of this cooperation gradually broadened and eventually it embraced all issues, which were considered to be critical for sustainable development. The summits on sustainability, namely, the UN Conference on Environment and Development in 1992, the “Rio+5” in 1997 and the World Summit on Sustainable Development in 2002, wished to respond to all unsustainable processes by adopting, reinforcing and expanding a global program. This program is based on a series of important principles and includes various goals and instruments adopted by consensus; however, it also reflects delicate compromises between development related aspirations and environmental barriers, and also between the developed and the developing countries. Actually, there is a serious implementation gap and there are also new challenges. Referring to these problems, the idea of convening an extraordinary summit in 2012 was raised and it was eventually adopted but with a rather narrow mandate and agenda. It turned out that besides the “usual” conflicts between the developed and developing countries e.g. upon the common but differentiated responsibilities or international development financing, there were also diverting views on the green economy and on the ways of institutional strengthening of the international sustainable development and environmental governance. As a consequence, the 2012 Conference concluded with rather modest results.

Az utóbbi évtizedben a környezettudatos gazdálkodás szerepének felértékelődése új tevékenységi területet nyitott meg a bankok előtt, amit nemzetközi szóhasználattal élve green banking-nek neveznek. A fenntartható fejlődést támogató projektek banki finanszírozása számos lehetőséget nyit a pénzügyi intézmények számára – hírnév, új ügyfélbázis, kockázatcsökkentés, jövedelmezőség növelése –, amennyiben a bankok a fenntarthatóság elveit megfelelően integrálják működési stratégiájukba. A cikksorozat második részében a szerzők a bankok fenntartható működését támogató külső és belső motiváló tényezőit veszik vizsgálat alá, amelyet már nemzetközi elvek és megállapodások is szabályoznak és támogatnak. Kiemelt fontosságot tulajdonítanak a környezettudatos gazdálkodás banki stratégiába történő integrálásának, melynek alapjait teremthetik meg a cikkben vizsgált nemzetközi irányelvek. ________ In the last decade, a lot of publications came to light, dealing with the social and environmental responsibility of financial institutions. Banks are expected to improve their competitive advantage by demonstrating economic development, while promoting environment care and social responsibility. This sustainable finance means to manage environmental and social risks in corporate lending and project financing. Green financial institutions have developed a wide range of innovations that can support sustainable development. This article highlights a few external and internal factor that support this aim, and which are regulated by international principles. However the authors’ survey shows that in the relevant literature there are a lot of ways to define sustainability and its achievement. They suggest that all of them can be interpreted associated with green banking operation. The goal of this paper is to identify the role of financial institutions in achieving sustainable development, and stress its strategic importance. The authors also attempt to show, why and how can this sector become the promoter of sustainability.

Iridescent blue leaf coloration in four Malaysian rain forest understory plants, Diplazium tomentosum Bl. (Athyriaceae), Lindsaea lucida Bi. (Lindsaeaceae), Begonia pavonina Ridl. (Begoniaceae), and Phyllagathis rotundifolia Bl. (Melastoma- taceae) is caused by a physical effect, constructive interference of reflected blue light. The ultrastructural basis for this in D. tomentosum and L. lucida is multiple layers of cellulose microfibrils in the uppermost cell walls of the adaxial epidermis. The helicoidal arrangement of these fibrils is analogous to that which produces a similar color in arthropods. In B. pavonina and P. rotundifolia the blue-green coloration is caused by parallel lamellae in specialized plastids adjacent to the abaxial wall of the adaxial epidermis. The selective advantage of this color production, if any, is unknown.

Globalization is eroding the livelihoods of small farmers, a significant and vulnerable class, particularly in the developing world. The cost-price squeeze stemming from trade liberalization places farmers in a race to the bottom that leads to displacement, poverty, and environmental degradation. Scholars and activists have proposed that alternative trade initiatives offer a unique opportunity to reverse this trend by harnessing the power of the markets to reward producers of goods with embedded superior cultural, environmental, and social values. Alternative trade via certification schemes have become a de facto prescription for any location where there is a need to conciliate economic interest with conservation imperatives. Partnerships among commodity production farmers, elite manufacturers and wealthy northern consumers/activists do not necessarily have win-win outcomes. Paradoxically, the partnerships of farmers with external agencies have unexpected results. These partnerships develop into dependent relationships that become unsustainable in the absence of further transfers of capital. The institutions born of these partnerships are fragile. When these fledging institutions fail, farmers are left in the same situation that they were before the partnership, with only minor improvements to show after spending considerable amounts of social and financial capital. I hypothesize that these failures are born out of a belief in a universal understanding of sustainability. A discursive emphasis on consensus, equity and mutual benefit hides the fact that what for consumers it is a matter of choice, for producers is a matter of survival. The growth in consumers’ demand for certified products creates a race for farmers to meet these standards. My findings suggest that this race generates economically perverse effects. First, producers enter into a certification treadmill. Second, the local need for economic sustainability is ignored. Third, commodity based alternative trade schemes increase the exposure of communities to global shocks. I conclude by calling for a careful reassessment of sustainable development projects that promote certification schemes. The designers and implementers of these programs must include farmers’ agenda in the planning of these programs.

The purpose of this study was to explore the attitudes, beliefs, and practices of community college professors regarding education for sustainable development (ESD). In-depth interviews with 14 professors from different disciplines were conducted. The participants taught at Miami Dade College, Florida, a Talloires Declaration signatory since 2006, and all had attended Green Studies professional development workshops. Written documents such as assignments and samples of student work were used for triangulation. The annual report of the college’s Earth Ethics Institute and its Web site served as additional sources. The interviews were recorded, transcribed, and analyzed for common themes. The Talloires Declaration’s 10-point action plan and the key characteristics of ESD (UN DESD, 2006) served as the conceptual framework. The study found that the professors considered ESD an essential issue. The majority discussed the economic and social aspects of ESD; however, the environmental aspect was mentioned most frequently. The professors’ conceptualizations of ESD were influenced by their experiences and evidenced by the metaphors they used. Although their engagement with ESD differed, the professors expressed optimism toward ESD related teaching and learning. They regarded ESD as compatible with their subjects, and most had already been infusing sustainability into their courses or planned to do so. Additionally, the participants’ teaching practices reflected many of the characteristics of ESD. Even though the professors considered ESD challenging, they believed that they could make contributions to the college’s effort. The metaphor of “Planting a Seed” was frequently used to describe this holistic approach. The study also found that many professors regarded interpersonal relationships and communication significant factors for the advancement of ESD. The participants described several challenges to integrating ESD at their college. These related to time constraints, density of curriculum, institutional size and fragmentation, dearth of administrative support and incentives, students’ lack of academic preparation and sustainability awareness, students’ inability to focus on ESD because of personal, social, or economic circumstances, and professors’ frustration about a divisive atmosphere as a result of their engagement with sustainability. Despite these obstacles, the professors believed that ESD could be successfully woven into the community college experience.

The future power grid will effectively utilize renewable energy resources and distributed generation to respond to energy demand while incorporating information technology and communication infrastructure for their optimum operation. This dissertation contributes to the development of real-time techniques, for wide-area monitoring and secure real-time control and operation of hybrid power systems. ^ To handle the increased level of real-time data exchange, this dissertation develops a supervisory control and data acquisition (SCADA) system that is equipped with a state estimation scheme from the real-time data. This system is verified on a specially developed laboratory-based test bed facility, as a hardware and software platform, to emulate the actual scenarios of a real hybrid power system with the highest level of similarities and capabilities to practical utility systems. It includes phasor measurements at hundreds of measurement points on the system. These measurements were obtained from especially developed laboratory based Phasor Measurement Unit (PMU) that is utilized in addition to existing commercially based PMU’s. The developed PMU was used in conjunction with the interconnected system along with the commercial PMU’s. The tested studies included a new technique for detecting the partially islanded micro grids in addition to several real-time techniques for synchronization and parameter identifications of hybrid systems. ^ Moreover, due to numerous integration of renewable energy resources through DC microgrids, this dissertation performs several practical cases for improvement of interoperability of such systems. Moreover, increased number of small and dispersed generating stations and their need to connect fast and properly into the AC grids, urged this work to explore the challenges that arise in synchronization of generators to the grid and through introduction of a Dynamic Brake system to improve the process of connecting distributed generators to the power grid.^ Real time operation and control requires data communication security. A research effort in this dissertation was developed based on Trusted Sensing Base (TSB) process for data communication security. The innovative TSB approach improves the security aspect of the power grid as a cyber-physical system. It is based on available GPS synchronization technology and provides protection against confidentiality attacks in critical power system infrastructures. ^

The non-timber forest products (NTFPs) sector in Nepal is being promoted with the concept of sustainable management as articulated by the Convention on Biological Diversity. To promote and regulate this sector, Nepal adopted the Herbs and NTFP Development Policy in 2004. The goal of this thesis was to assess the effectiveness of this policy along with other forestry and natural resource policies in Nepal concerning the conservation and sustainable use of NTFPs. I conducted open-ended semi-structured interviews with 28 key informants in summer 2006 in Nepal where I also collected relevant documents and publications. I did qualitative analysis of data obtained from interviews and document review. The research found many important issues that need to be addressed to promote the NTFP sector as envisioned by the Government of Nepal. The findings of this research will help to further implement the policy and promote the NTFP sector through sustainable management practices.
