Salir de la escuela: entre la tradición y la educación ambiental para la sostenibilidad = Excursions from school: between tradition and environmental education for sustainability

Las actividades escolares fuera del centro constituyen una marca de calidad del pasado y del presente educativo, y tienen que seguir siéndolo en el futuro. A partir de una investigación cualitativa se identifican las razones aducidas por enseñantes para salir del aula y, con ejemplos concretos, quedan plasmados algunos de los objetivos perseguidos, así como otros que se añaden a la propia actividad. Se identifican salidas vivenciales y otras más experimentales, se reconocen valores positivos, pero también se echa en falta un trabajo más coherente con los principios actuales de la educación ambiental. Precisamente esta educación es la propuesta como el camino a seguir para renovar objetivos, técnicas y procedimientos para salir del aula

Mining in Developing Countries: A Case Study of Sustainability Challenges

Mining has severe impacts on its surrounding. Particularly in the developing countries it has degraded the environment and signigicantly altered the socio-economical dynamics of the hosts. Especially relocation disrupts people from their homes, livelihoods, cultures and social activities. Mining industry has failed to develop the local host and streghten its governance structures; instead it has further degraded the development of mineral rich third world countries, which are among the world poorest ones. Cash flows derived from mining companies have not benefitted the crass-root level that however, bears most of the detrimental impacts. Especially if the governance structure of the host is weak, the sudden wealth is likely to accelerate disparities, corruption and even fuel wars. Environmental degradation, miscommunication, mistrust and disputes over land use have created conflicts between the communities and a mining company in Obuasi, Ghana; a case study of this thesis. The disputes are deeply rooted and further fuelled by unrealistic expectations and broken promises. The relations with artisanal and illegal miners have been especially troublesome. Illegal activities, mainly encroachment of the land and assets of the mine, such as vandalising tailings pipes have resulted in profits losses, environmental degradation and security hazards. All challenges mentioned above have to be addressed locally with site-specific solutions. It is vital to increase two-way communication, initiate collaboration and build capacity of the stakeholders such as local communities, NGOs and governance authorities. The locals must be engaged to create livelihood opportunities that are designed with and for them. Capacity can also be strengthened through education and skills training, such as women’s literacy programs. In order to diminish the overdependence of locals to the mine, the activities have to be self -sufficient and able to survive without external financial and managerial inputs. Additionally adequate and fair compensation practises and dispute resolution methods that are understood and accepted by all parties have to be agreed on as early as possible.

Regional innovation strategies and sustainability in selected EU countries

This study focuses on regional innovation strategy (RIS) and sustainability aspects in selected regions of European Union (EU) countries. It is known that RIS helps a region to innovate locally and to compete globally and it is considered as one of the main policy tools of the EU for innovation support at a regional level. This study is conducted to explore the existence and adoption of RIS in different regions of selected EU countries, and to highlight and compare regional RIS characteristics. The study is also aimed at identifying the factors that characterise the formulation and implementation of RIS as well as the problems associated thereof. In this study, six regions of EU countries are considered: Päijät-Häme Region (Finland); London Region (United Kingdom); Mid-West Region (Ireland); Veneto Region (Italy); Eastern Region (Poland); and West Region (Romania). Data and information are collected by sending questionnaires to the respective regional authorities of these selected regions. Based on the gathered information and analysis, RIS or equivalent strategy document serves as a blueprint for forwarding innovative programmes towards regional sustainability. The objectives of RIS in these regions are found to be dependent on the priority sectors and state of the region’s development. The current environmental sustainability aspects are focused on eco-design, eco-products, and eco-innovation, although each region also has its own specific aspects supported by RIS. Likewise, regional policies typically follow the RIS yet translated in various sectoral focus or priority areas. The main enhancing factors supporting RIS among selected regions have some similarities and variations; among others, some regions are strongly supported by EU while others have support from own regional agencies, organisations and professional networks. RIS implementation is not without challenges and despite the differences in challenges, almost all of reviewed regions consider financial resource as a common problem. Generally, it is learned from this study that RIS and regional sustainability are reinforcing each other mutually. In this study, the strong focus is given towards environmental sustainability in the regions although regional sustainability also includes economic and social aspects. A well-focused and prioritised RIS is beneficial for regional sustainable development.

Quantitative Sustainability Disclosure –An international comparison and its impact on investor valuation

This research focuses on the link between quantitative sustainability disclosure and information asymmetry. It builds upon previous research which links information asymmetry with voluntary disclosure. Stakeholders from the financial services sector claim that sustainability disclosure needs to be more numerical and comparable between companies. This research covers 111 firms from Denmark, Finland, the Netherlands and Sweden from non-service industries and studies how quantitative their sustainability disclosure is, and whether or not there is a negative relation with information asymmetry. The results support the hypotheses, where two out of three information asymmetry proxies have a significant negative relation with quantitative disclosure. Size is supported as a moderating factor. Quantitativity also proves to have a significant link with third party sustainability ratings. The direct link between quantitativity and cost of capital is not however supported.

Diversidade e índice sucessional de uma vegetação de cerrado sensu stricto na Universidade Estadual de Goiás-UEG, campus de Anápolis

A composição vegetal, estrutura, diversidade, estádio sucessional e distribuição de espécies do cerrado do campus da UEG com 6 ha, foram inventariados usando 30 parcelas com 100 m² cada. A partir de dbs superior ou igual a 5 cm foram amostrados 515 indivíduos, representados por 20 famílias, 28 gêneros e 46 espécies. As famílias de maior riqueza foram Leguminosae, Vochysiaceae e Malpighiaceae. As espécies Qualea grandiflora, Byrsonima crassa, Erytroxylum tortuosum, Qualea parviflora e Miconia ferruginata apresentaram os maiores VIs. A diversidade da área (H¢ = 1,353) é menor que valores descritos para Cerrado, o que pode ser conseqüência tanto da abundância de espécies como Q. grandiflora e B. crasssa quanto de interferências antrópicas no local, incluindo queimadas. O valor do índice sucessional (IS = 2,3) indica uma comunidade em estágio intermediário de sucessão, já que seu valor oscila de 1 a 3 . A comunidade ajustou-se apenas ao modelo log-normal, o que, de acordo com a literatura, pode ser influência da proporção da abundância de espécies dominantes, intermediárias e raras.

Densidade e composição florística do banco de sementes de um trecho de floresta estacional semidecidual no campus da Universidade Federal de Viçosa, Viçosa, MG

O objetivo deste trabalho foi caracterizar o banco de sementes de um trecho de Floresta Estacional Semidecidual Secundária, por meio da análise florística e da densidade de sementes. Denominado Mata da Praça de Esportes, o fragmento está situado no Campus da UFV, em Viçosa, MG, cuja área corresponde a 10,65 ha em regeneração há 75 anos. A área amostral foi subdividida em 40 parcelas de 3 x 5 m, distribuídas em quatro transectos paralelos. Amostras compostas foram feitas em 20 dessas parcelas e posteriormente distribuídas dentro de 40 caixas de madeira, em viveiro. O montante foi dividido, submetendo-se cada metade a sombreamentos de 11,5% e 60%. A germinação total e das espécies arbustivo-arbóreas foi comparada nas duas condições de sombreamento, utilizando-se o teste t para amostras independentes. O banco de sementes foi constituído predominantemente por ervas invasoras, pertencentes, em sua maioria, às famílias Asteraceae (15 espécies), Solanaceae (4 espécies) e Poaceae (3 espécies). Foram quantificadas 5.194 plântulas, com predomínio das pioneiras arbustivo-arbóreas das famílias Melastomataceae e Cecropiaceae. A germinação das sementes conduzida sob sombra foi significativamente maior do que no ambiente de menor sombreamento (luz). Espécies zoocóricas foram mais abundantes, indicando a importância dos fragmentos florestais como fonte de recurso e abrigo para a fauna local. A alta densidade de indivíduos de espécies arbóreas e arbustivas pioneiras, como Cecropia hololeuca, as espécies de Melastomataceae, Asteraceae e Piperaceae, importantes para a regeneração da floresta, reflete a capacidade de resiliência da área estudada, na ocorrência de distúrbios.

Energetic sustainability of three arabica coffee growing systems used by family farming units in Espírito Santo state

Three growing systems of Arabica coffee were evaluated under the energy perspective, in the state of Espírito Santo in Brazil. The systems are conventional cultivation (CC), cultivation with good agricultural practices (CGP) and organic farming (OF). It was made a comparison of the energy flows within these three systems to show sustainable levels of each one based on production average data of several family-farming units. Therefore, we analyzed crop yield, total energy efficiency reverse (TEER), energy efficiency of ripe coffee (EERC) and non-renewable energy efficiency (NREE). OF system had values for TEER, EERC and NREE of 3.3 4.7 and 7.9 respectively. Yet CC showed values of 1.8, 1.9 and 1.6 for TEER, EERC and NREE respectively. Furthermore, CGP presented values for TEER, EERC and NREE of 0.7, 1.3 and 1.4 respectively. The highest yield was observed in CGP, reaching an amount of 1794 kg ha-1(17,455 MJ); however, this system expends more energy than it converts. Thus, over those points, OF is the most sustainable system.

THE ROLE OF INFORMATION TECHNOLOGY IN CREATING SUSTAINABILITY VALUE FOR FINANCIAL INSTITUTIONS IN 2020 : a scenario planning approach

The growing importance of global sustainability issues has been causing many changes to the financial services industry. Facts such as climate change, social development and the financial crisis in 2008 have been making banks reconsider the manner that they consider environmental, social and economic factors in their decision-making process. At the same time, information technology (IT) has been transforming the financial service industry and its fast development has casted doubts on the way it should be managed within an organization. This current changing environment brings a number of uncertainties to the future that cannot be addressed using traditional forecasting techniques. This research investigates how IT can bring value to sustainability in the financial service industry in 2020. Through the use of a scenario planning technique, we analyzed how trends in the current environment (considering the relation between sustainability, financial institutions an IT) can lead to four different future scenarios. Then, we discussed how IT can improve a bank’s sustainability performance, considering the limitations of each scenario.

Disruptive innovations at the bottom of the pyramid : can they impact the sustainability of today´s top companies?

Due to the different dynamics required for organizations to serve the emerging market which contains billions of people at the bottom of the pyramid (BOP) coupled with the increasing desire for organizations to grow and be more multinational, organizations need to continually innovate. However, the tendency for large and established companies to ignore the BOP market and rather focus on existing markets, gives an indication of the existence of a vulnerability that potentially disruptive innovations from the BOP will not be recognized in good time for a counter measure. This can be deduced from the fact that good management practice advocates that managers should learn and listen to their customers. Therefore majority of the large existing companies continually focus on their main customer/market with sustaining innovations which leaves aspiring new entrants with an underserved BOP market to experiment with. With the aid of research interviews and an agent-based model (ABM) simulation, this thesis examines the attributes of BOP innovations that can qualify them as disruptive and the possibilities of tangible disruptive innovations arising from the bottom of the pyramid and their underlying drivers. The thesis Furthermore, examines the associated impact of such innovations on the future sustainability of established large companies that are operating in the developed world, particularly those with a primary focus which is targeted towards the market at the top of the pyramid (TOP). Additionally, with the use of a scenario planning model, the research provides an evaluation of the possible evolution and potential sustainability impacts that could emerge, from the interplay of innovations at the two pyramidal market levels and the chosen market focus of organizations – TOP or BOP. Using four scenario quadrants, the thesis demonstrates the resulting possibilities from the interaction between the rate of innovations and the segment focused on by organizations with disruptive era characterizing the paradigm shift quadrant. Furthermore, a mathematical model and two theoretical propositions are developed for further research. As recommendations, the thesis also extends the ambidextrous organizational theory, business model innovation and portfolio diversification as plausible recommendations to limit a catastrophic impact, resulting from disruptive innovations.

Comparison of sustainability of technologies for water desalination

The aim of this work is to perform an in-depth overview on the sustainability of several major commercialized technologies for water desalination and to identify the challenges and propose suggestions for the development of water desalination technologies. The overview of those technologies mainly focuses on the sustainability from the viewpoint of total capital investment, total product cost, energy consumption and global warming index. Additionally, a systematic sustainability assessment methodology has been introduced to validate the assessment process. Conclusions are:1) Reverse osmosis desalination (RO) plants are better than multi-stage flash distillation (MSF) desalination plants and multiple-effect distillation (MED) desalination plants from the viewpoint of energy consumption, global warming index and total production cost; 2)Though energy intensive, MSF plants and MED plants secure their advantages over RO plants by lower total capital investment, wider applicability and purer water desalted and they are still likely to flourish in energy-rich area;3) Water production stage and wastewater disposal stage are the two stages during which most pollutant gases are emitted. The water production stage alone contributes approximately 80~90% of the total pollutant gases emission during its life cycle; 4)The total capital cost per m3 desalted water decreases remarkably with the increasing of plant capacity. The differences between the capital cost per m3 desalted water of RO and other desalination plants will decrease as the capacity increases; 5) It is found that utilities costs serve as the major part of the total product cost, and they account for 91.16%, 85.55% and 71.26% of the total product cost for MSF, MED and RO plants, respectively; 6) The absolute superiority of given technology depends on the actual social-economic situation (energy prices, social policies, technology advancements).

Relações hídricas em espécies lenhosas no campus Pampulha/UFMG, Belo Horizonte, MG

O presente trabalho objetivou avaliar as relações hídricas em função da demanda evaporativa e da densidade da madeira em Swietenia macrophylla King, Joannesia princeps Vell., Inga edulis Mart., Licania tomentosa (Benth.) Fritsch e Centrolobium tomentosum Guill. ex Benth. O potencial hídrico foi determinado com uma câmara de pressão e a condutância estomática, com porômetro de difusão na estação chuvosa, na estação seca e nas situações transicionais. J. princeps foi a espécie que apresentou maiores valores de potencial hídrico no "predawn" (psiPD > - 0,25 Mpa), e I. edulis os menores valores (psiPD = - 1,5 MPa). J. princeps apresentou maiores valores de potencial hídrico durante o dia (psiMD > - 1,5 MPa), e os menores valores foram observados em S. macrophylla e I. edulis (psiMD < - 3,0 MPa). As amplitudes diárias do potencial hídrico (Dy = psiMD - psiPD) foram relacionadas positivamente com o déficit de pressão de vapor (DPV) e os maiores valores foram observados em S. macrophylla e I. edulis. Geralmente a condutância diminuiu no início da tarde e I. edulis apresentou menor restrição à transpiração. Os maiores valores de condutância foram observados em um dia nublado na estação chuvosa, com baixo DPV. Uma regressão quadrática (r² = 0,635, p < 0,01) sugere que, não necessariamente, as espécies com maior densidade apresentam maior Dy, uma vez que pode ocorrer uma grande restrição à perda d'água como verificado em L. tomentosa, a espécie com madeira mais densa.
