Polluting production – environmentally sound alternatives; A general model of production externalities

With the determination of principal parameters of producing and pollution abatement technologies, this paper quantifies abatement and external costs at the social optimum and analyses the dynamic relationship between technological development and the above-mentioned costs. With the partial analysis of parameters, the paper presents the impacts on the level of pollution and external costs of extensive and intensive environmental protection, market demand change and product fees, and not environmental protection oriented technological development. Parametrical cost calculation makes the drawing up of two useful rules of thumb possible in connection with the rate of government in-terventions. Also, the paradox of technological development aiming at intensive environmental protection will become apparent.

Biomass gasification: Environmentally sound technology for decentralized power generation, a case study from India

This study aims at understanding the need for decentralized power generation systems and to explore the potential, feasibility and environmental implications of biomass gasifier-based electricity generation systems for village electrification. Electricity needs of villages are in the range of 5–20 kW depending on the size of the village. Decentralized power generation systems are desirable for low load village situations as the cost of power transmission lines is reduced and transmission and distribution losses are minimised. A biomass gasifier-based electricity generation system is one of the feasible options; the technology is readily available and has already been field tested. To meet the lighting and stationary power needs of 500,000 villages in India the land required is only 16 Mha compared to over 100 Mha of degraded land available for tree planting. In fact all the 95 Mt of woody biomass required for gasification could be obtained through biomass conservation programmes such as biogas and improved cook stoves. Thus dedication of land for energy plantations may not be required. A shift to a biomass gasifier-based power generation system leads to local benefits such as village self reliance, local employment and skill generation and promotion of in situ plant diversity plus global benefits like no net CO2 emission (as sustainable biomass harvests are possible) and a reduction in CO2 emissions (when used to substitute thermal power and diesel in irrigation pump sets).

A proposal for a clean technology directive: European patent law and climate change

This article charts the conflicted, dissonant policies of the European Union towards intellectual property and climate change. It contends that there is a mismatch between the empirical work of the European Patent Office and the quietist policy options contemplated by the European Union. This article contends that the European Union needs to develop a Clean Technology Directive to allow for a differentiated approach to patent law and clean technologies - especially given the past complicity of the European Union in global warming and climate change. It highlights essential elements in a comprehensive policy package for the reform of patent law - considering patentable subject matter; patent incentives; and patent exceptions.

Rio+ 20: Who owns the green economy?

The Rio+20 summit has raised a number of difficult questions about law and technology: what is the relationship between intellectual property and the environment? What role does intellectual property play in sustainable development? Who will own and control the Green Economy? What is the best way to encourage the transfer of environmentally sound technologies? Should intellectual property provide incentives for fossil fuels? What are the respective roles of the public sector and the private sector in green innovation? How should biodiversity, traditional knowledge and Indigenous intellectual property be protected?

Renewable energy and energy conservation technologies

Energy systems should be consistent with environmental, economic and social sustainability in order to ensure regional sustainable development. This enhances both current and future potential to meet the human needs and aspirations. Sustainable development, a process of change, in which, the exploitation of resources, the direction of investments , the orientation of technological development and institutional change are in harmony. National energy programme should prioritize the development of renewable energy sources, which offer the potentially huge sources of primary energy. The path for sustainability in the next millennium is the low energy path through wise use of energy. Energy conservation and energy efficiency measures would certainly result in meeting the energy demand with as little as half the primary supply at current levels. This requires profound structural changes in socio-economic and institutional arrangements. Environmentally sound, technically and economically viable energy pathways will sustain human progress in the long term future giving a fair and equitable share of the underprivileged and poor of the developing countries. Renewable energy is considered by some as the only hope for the survival of planet yet by others it is viewed as a marginal resource with limited resource. All too often, however, the facts behind the role that renewable energy can, and will, play in the regional energy scene are disguised or ignored as rival camps distort the evidence to suit their own objectives. It was in the light of this confusion that the Energy Research Group at Centre for Ecological Sciences, Indian Institute of Science undertook investigation in Kolar and Uttara Kannada Districts in Karnataka State, India to identify the potential contribution of several types of renewable energy sources: Solar, Wind, Hydro, Bioenergy, etc.

Urban Growth Analysis Using Spatial and Temporal Data

Urban growth identification, quantification, knowledge of rate and the trends of growth would help in regional planning for better infrastructure provision in environmentally sound way. This requires analysis of spatial and temporal data, which help in quantifying the trends of growth on spatial scale. Emerging technologies such as Remote Sensing, Geographic Information System (GIS) along with Global Positioning System (GPS) help in this regard. Remote sensing aids in the collection of temporal data and GIS helps in spatial analysis. This paper focuses on the analysis of urban growth pattern in the form of either radial or linear sprawl along the Bangalore - Mysore highway. Various GIS base layers such as builtup areas along the highway, road network, village boundary etc. were generated using collateral data such as the Survey of India toposheet, etc. Further, this analysis was complemented with the computation of Shannon's entropy, which helped in identifying prevalent sprawl zone, rate of growth and in delineating potential sprawl locations. The computation Shannon's entropy helped in delineating regions with dispersed and compact growth. This study reveals that the Bangalore North and South taluks contributed mainly to the sprawl with 559% increase in built-up area over a period of 28 years and high degree of dispersion. The Mysore and Srirangapatna region showed 128% change in built-up area and a high potential for sprawl with slightly high dispersion. The degree of sprawl was found to be directly proportional to the distances from the cities.

Paisaje de energías: conocimiento estético en el enfoque ambiental del proyecto

Desde hace ya varias décadas la praxis de la ecología ha venido reconociendo la necesidad de estudiar los múltiples sistemas de interacción del ser humano, como especie viva, y su entorno. Entidades espaciales como el paisaje geográfico son empleadas para delimitar sistemas territoriales operados por la sociedad, precisando campos concretos de su acción física, biológica y cultural. La ecología aborda así el conocimiento científico del territorio como asentamiento humano, rastrea sus patrones espaciales y analiza su compleja estructura funcional. En ese contexto, la transferencia de herramientas e instrumentos desde la ecología al ámbito proyectivo posee ya un bagaje de más de cinco décadas. Cada vez con más frecuencia el proyecto emplea parámetros, inventarios, fórmulas, indicadores y tecnologías que tratan de dar una respuesta ambientalmente adecuada a los condicionantes de contorno, por ejemplo aprovechando las condiciones climáticas en la optimización energética o proponiendo programas de usos del suelo que eviten perturbaciones en ecosistemas de interés. Con todo, en el momento presente surgen voces que, ante el dominio indiscutible de los enfoques netamente deterministas, tratan de recordar que los principios del pensamiento ecológico van más allá del mero control cuantitativo de los procesos biofísicos. Recuerdan que la etología demostró a principios del XX que el ser humano, como ser consciente, inviste una relación de intimidad con su entorno que supera tales perspectivas: a través de la correspondencia entre percepción y significación, entre lo físico y lo psíquico, entre interioridad y exterioridad, las personas abrazan la plenitud de aquello que les rodea en un acto de profunda conciliación afectiva. De tal ligadura de intimidad depende, sí o sí, y en toda su profundidad, la aceptación humana del entorno construido. A través de la noción de ambiente [Umwelt] se demuestra que la relación del hombre con su entorno es inseparable, bidireccional y coordinada y, por lo tanto, desde una posición coherente, la experiencia del espacio puede ser examinada a partir de la reciprocidad que constituyen, en continuidad, la persona y el lugar. De esta forma, la tesis dirige su objetivo principal a explorar y considerar, desde el proyecto, el significado y la influencia de la experiencia ambiental del espacio construido en la vida humana. Es más que probable que buena parte de los problemas de desafección del hombre con los paisajes transformados de su contemporaneidad tenga que ver con que tanto las intensidades de la experiencia y percepción humana, como la potestad interpretativa de sus productos culturales, incluyendo la arquitectura, han sido fuertemente reducidas. Ante este problema, la investigación toma como hipótesis la oportunidad que ofrece el pensamiento ecológico de reformular la experiencia estética como un acto de conocimiento, como un evento donde se da el encuentro físico y se construyen significados, donde se sancionan valores sociales y se mira hacia el futuro. Se ha de señalar que la presente tesis doctoral arranca en el Laboratorio de Paisaje del Grupo de Investigación Paisaje Cultural de la Universidad Politécnica de Madrid dirigido por Concha Lapayese y Darío Gazapo, y por tanto hace suyos para el estado del arte los principales conceptos e ideas bajo los que el trabajo teórico y práctico del grupo se viene orientando desde hace años: la consideración del paisaje como acontecimiento; la oscilación de la interpretación entre un paisaje específico y un paisaje genérico en un mundo globalizado; el reconocimiento de la experiencia estética del paisaje como una toma de conciencia social; y en definitiva, la reivindicación de la interioridad en el proyecto contemporáneo. La investigación profundiza en una línea de oportunidad que se abre al promover lo que se ha llamado un conocimiento por lo sentido como estrategia ambiental que permite contrarrestar mitos profundamente arraigados en las estructuras sociales. El primer paso en ese recorrido sería explorar ecológicamente el aporte de la experiencia estética; esto es, su consideración como forma de conocimiento específico. Resultaría pertinente impulsar la idea de la inmersión en el paisaje como fenómeno experiencial, sensual y corporal, y enfrentar, desde ahí, el problema de la aceptación social de lo nuevo y lo trasformado de acuerdo con el momento actual. La exploración sobre la afectividad en el ambiente no es, en cualquier caso, un asunto nuevo. Sin pretensiones de historiografía, dos momentos del siglo XX concentran el interés de la investigación. La primera se corresponde fundamentalmente con la segunda década del siglo, en relación a una serie de influencias que desde los avances científicos determinaron singulares aventuras del arte más experimental. La segunda se posiciona en el entorno de 1970, época en la que es conocido el interés que despertaron las cuestiones ambientales. En ambos casos se han estudiado aportaciones que desvelan conceptos determinantes en la definición de la experiencia estética como un evento de adquisición de conocimiento por lo sentido. Es conveniente adelantar el rol de centralidad que para la investigación tiene el concepto de energía, tal como el propio título subraya. La energía como realidad material y sensible es el sustrato que permite navegar por el principio de unidad epistemológica que subyace al pensamiento ecológico. Sus continuas referencias simbólicas, físicas y metafóricas entre los artistas estudiados no son un mero recurso iconográfico: mantienen inherente el principio de continuidad ambiental en el cual el ser humano y la inmensidad del cosmos navegan indisociables. Un discurso unificado y consistente sobre los aportes de la experiencia estética enfocada como forma de conocimiento por lo sentido hila la lectura histórica, conceptual y práctica de toda la investigación. Con ello se alcanza a hilvanar un diagrama conceptual, modelo de análisis proyectivo, que recoge ideas científicas, filosóficas y proyectivas. De alguna manera, el diagrama trata de dibujar, desde los principios del pensamiento ecológico, la correlación de continuidad que, vacilante, tensa, sutil y frágil se desplaza incesante e irresuelta entre interioridad y exterioridad. ABSTRACT Over the last few decades ecological practice has come to acknowledge a need for studying the multiple systems of interaction between the human being - inasmuch as it is a living species - and its environment. Spatial entities such as the geographic notion of landscape have been used to delimitate the territorial systems operated by society and to describe in detail specific fields of its physical, biological and cultural action. Ecology has thus managed to address the scientific knowledge of the territory as a human settlement, tracking its spatial patterns and analysing its complex functional structure. In this context, the transfer of tools and instruments from the field of ecology to that of design has a tradition already going back more than fifty years. Increasingly more often, design makes use of parameters, inventories, formulas, indicators and technologies to give an environmentally sound response to contour conditions: for instance, taking advantage of the local climate for the optimisation of energy consumption or proposing land uses that avoid disturbing valuable ecosystems. Yet in the present day some voices have arisen that, against the uncontested domination of purely positivistic approaches, are trying to draw attention to the fact that the principles of ecological thought go beyond mere quantitative control of biophysical processes. They point out that, in the early 20th century, ethology proved that the human being, as a conscious entity, invests itself into a relationship of intimacy with its environment that surpasses such perspectives: through the correspondences between perception and signification, between physical and psychological or between inside and outside, people embrace the entirety of their surroundings in an action of deep affective conciliation. It is on this link of intimacy that - fully and unquestionably - human acceptance of the built environment depends. Through the notion of environment [Umwelt] it can be proven that the relationship between the human being and its environment is inseparable, bidirectional and coordinated; and that, therefore, from a coherent position the experience of space can be examined through the reciprocity constituted continuously by person and place. Thus, the main goal in this thesis is to explore and acknowledge, from the standpoint of design, the meaning and influence of the environmental experience in human life. It is extremely likely that many of the issues with mankind’s alienation from the transformed landscapes of the present day arise from the fact that both the intensity of human perception and experience and the interpretive capacity of its cultural products –including architecture - have been greatly reduced. Facing this issue, research has taken as hypothesis the opportunity offered by ecological thought of reformulating aesthetic experience as an act of knowledge – as an event where physical encounter takes place and meanings are constructed; where social values are sanctioned and the path towards the future is drawn. This notwithstanding, the present thesis began in the Landscape Laboratory of the Technical University of Madrid Cultural Landscape Research Group (GIPC-UPM), led by Concha Lapayese and Darío Gazapo; and has therefore appropriated for its state of the art the main concepts and ideas that have been orienting the practical and theoretical work of the latter: the understanding of landscape as an event, the oscillation of interpretation between a specific and a generic landscape within a globalised world; the acknowledgement of the aesthetic experience of landscape as a way of acquiring social awareness; and, all in all, a vindication of interiority in contemporary design. An exploration has been made of the line of opportunity that is opened when promoting what has been termed knowledge through the senses as an environmental strategy allowing to counter myths deeply rooted in social structures. The first step in this path would be an ecological exploration of the contribution of the aesthetic experience; that is, its consideration as a type of specific knowledge. It would be pertinent to further the idea of immersion into the landscape as an experiential, sensual and corporeal phenomenon and, from that point, to face the issue of social acceptance of what is new and transformed according to the values of the present day. The exploration of affectivity in the environment is not, at any rate, a new topic. Without aspiring to make a history of it, we can mark two points in the 20th century that have concentrated the interest of this research. The first coincides with the second decade of the century and relates to a number of influences that, arising from scientific progress, determined the singular adventures of the more experimental tendencies in art. The second is centred around 1970: a period in which the interest drawn by environmental matters is well known. In both cases, contributions have been studied that reveal crucial concepts in defining the aesthetic experience as an event for the acquisition of knowledge through the senses. It is necessary to highlight the role of centrality that the concept of energy has throughout this research, as is evident even in its title. Energy as a material, sensitive reality is the substrate making it possible to navigate through the principle of epistemological unity underlying ecological thought. The continuous symbolic, physical and metaphorical references to it among the artists studied here are not a mere iconographic source: they remind of the inherency of the principle of environmental continuity within which the human being and the immensity of cosmos travel indissociably. A unified, consistent discourse on the contributions of the aesthetic experience addressed as knowledge through the senses weaves together the historic, conceptual and practical reading of the whole research. With it, a conceptual diagram is constructed – a model of design analysis – gathering together scientific, philosophical and design ideas. Somehow, the diagram tries to draw from the principles of ecological thought the correlation of continuity that, vacillating, tense, subtle and fragile, shifts incessantly and unresolved between interiority and exteriority.

Acibenzolar-S-methyl and methyl jasmonate treatments of glasshouse-grown freesias suppress post-harvest petal specking caused by Botrytis cinerea

Compounds that activate host plant defence responses potentially offer socio-environmentally sound alternative methods for disease control. In a series of glasshouse trials over 2 years, pre-harvest sprays with acibenzolar-S-methyl (ASM) and methyl jasmonate (MeJA) were tested for suppression of post-harvest infection of cut Freesia hybrida L. flowers by Botrytis cinerea. For the ASM treatments, variability in reducing the incidence of B. cinerea disease was observed between years freesia varieties, incubation temperatures and ASM concentrations. In the first year, the greatest reductions in lesion numbers on ASM-treated var. 'Cote d'Azur' were recorded using 2.86 mM ASM. For three different post-harvest temperature regimes, the relative reductions in lesion numbers, compared to untreated controls, were 45% at 5 degrees C, 40% at 12 degrees C and 30% at 20 degrees C, respectively. In the second year, lesion numbers were most reduced using 1.43 mM ASM to treat freesia var. 'Dukaat' flowers. Here, the relative reductions were to 44% at 5 degrees C, 26% at 12 degrees C and 51% at 20 degrees C. MeJA treatments were, in general, more consistently effective than ASM treatments in reducing lesion numbers and lesion diameters on cut freesia flowers. MeJA-treated (0.2 mM) freesia flowers (var. 'Dukaat') incubated at 20 degrees C showed relative reductions of 62%, and 45% for lesion number and lesion diameter, respectively. The differing efficacy between ASM and MeJA treatments could be attributed to their differential abilities to induce the salicylic acid (SA)-mediated vs. the jasmonic acid (JA)-mediated host defence pathways, respectively.

Sonic technologies of postmodernity and the grain of the voice in Robert Lepage’s Lipsynch

This paper unpacks the relationships between the human voice and sound technologies by re-reading and re-evaluating Roland Barthes seminal essay, ‘The Grain of the Voice’ an oft cited but frequently misunderstood text, in the light of Robert Lepage’s Lipsynch (Canada, 2012). This production explicitly uses analogue and digital sound technologies to reveal the complexities and contradictions operating within the sonic economy of the performance with particular reference to the way it uses digital dubbing, miming, voice-overs and lip-reading to unsettle assumptions about the connections between the language, speech and the human voice. The paper will also unsettle any simple understanding of the voice as the locus of identity, and uncover the manner in which sonic digital technologies enable us to better apprehend ‘the body in the voice as it sings, the hand as it writes, the limb as it performs’ (Barthes, 185) while remaining sceptical about the existence of a primordial, unconstructed body.

Environmental pollution from shipbreaking industry : international law and national legal response

The international legal regime on shipbreaking is in its formative years. At the international level, the shipbreaking industry is partially governed by the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal. However, how far this convention will be applicable for all aspects of transboundary movement of end-of-life ships is still, at least in the view of some scholars, a debatable issue. Against this backdrop, the International Maritime Organisation (IMO) has adopted a new, legally binding convention for shipbreaking. There is a rising voice from the developing countries that the convention is likely to impose more obligations on recycling facilities in the developing countries than on shipowners from rich nations. This may be identified as a clear derogation from the globally recognized international environmental law principle of common but differentiated treatment. This article will examine in detail major international conventions regulating transboundary movement and environmentally sound disposal of obsolete ships, as well as the corresponding laws of Bangladesh for implementing these conventions in the domestic arena. Moreover this article will examine in detail the recently adopted IMO Ship Recycling Convention.

Identification of genes involved with tick infestation in Bos taurus and Bos indicus

Tick resistant cattle could provide a potentially sustainable and environmentally sound method of controlling cattle ticks. Advances in genomics and the availability of the bovine genome sequence open up opportunities to identify useful and selectable genes controlling cattle tick resistance. Using quantitative real-time PCR and the Affymetrix bovine array platform, differences in gene expression of skin biopsies from tick resistant Bos indicus (Brahman) and tick susceptible Bos taurus (Holstein-Friesian) cattle following tick challenge were examined. We identified 138 significant differentially-expressed genes, including several immunological/host defence genes, extracellular matrix proteins, and transcription factors as well as genes involved in lipid metabolism. Three key pathways, represented by genes differentially expressed in resistant Brahmans, were identified; the development of the cell-mediated immune response, structural integrity of the dermis and intracellular Ca 2+ levels. Ca2+, which is implicated in host responses to microbial stimuli, may be required for the enhancement or fine-tuning of transcriptional activation of Ca2+- dependant host defence signalling pathways.
