3.1 Introduction So what are the principal energy systems used by humanity at present, and how sustainable are they? Until quite recently, human energy requirements were modest and our supplies came either from harnessing natural processes such as the growth of plants, which provided wood for heating and food to energise human or animal muscles, or from the power of water and wind, used to drive simple machinery.
2.4 Natural science valuation: towards ecological restoration While the previous two subsections dealt with the social sciences, the ideas of ecology represent more the natural sciences tradition. In the early years of controversy around how to practise sustainable development, some concern was expressed about the perceived bias towards social rather than natural sciences. Bryan Norton (1992), for example, is critical of the social scientific approach. He argues that reliance on standard economic and other social scientific tools will not be enough to e

5.3.4 Plan testing and validation It is one thing to have a plan; it is another thing to have a plan that you can rely on to work. There is an old military maxim that ‘A plan only gets you into first contact with the enemy. After that, you fly by the seat of your pants’ (Anon). A 1993 IBM report on business continuity planning confirmed this when it revealed that ‘half of the plans failed completely or substantially when they were first tested’ (IBM, 1993, p. 5). The IBM report identified three categories of pla
4.1 Introduction Annual costs to employers from accidental injury and occupational illness are on the order of 5–10 per cent of the gross profits of UK industry. The total social cost, including the cost of benefits and National Health hospitalisation and treatment, make this a truly staggering drain on the nation's coffers! 2 Setting priorities Consider whether the relative economic aspects should determine the degree of priority given to different aspects of the risk scenarios in Author(s): Learning outcomes After studying this course, you should be able to: define risk in the most appropriate way, and appreciate the need to prioritise risks appreciate the costs of illness associated with workplace activities describe in outline the development of models used to explain the cause of incidents and to promote prevention recognise the multiple causes contributing to many incidents, and be able to represent them diagrammatically 4.5 The Kew Gardens Millennium Seed Bank Appeal Acknowledgements Cover image: reynermedia in Flickr made available under Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence.

One such model was developed in the 1950s and 1960s by Abraham Maslow. Although it exists in many variants it is generally known as Maslow's hierarchy of human needs. In the most common interpretations it places the fundamental material needs of survival, such as food, shelter and safety at the base of a triangle, rising through social needs of belonging in human society, to 3.2 The agreement to protect the ozone layer After a decade of controversy about the possible effects of CFCs, in 1985 British scientists discovered over the Antarctic a quite unexpected 'hole' in the ozone layer which was the size of the USA. This helped to galvanise the international community into action (though some who took part in the negotiations claim it played little part). By 1987 the first international agreement to control substances damaging to the ozone layer, the Montreal Protocol, was established. Interestingly th 2.4 Changing environmental attitudes So, from the start of the Industrial Revolution, people have been aware that the development of an industrial economy brings problems as well as benefits. But the benefits, in terms of productive capability, mobility, convenience, cheap consumer goods, and profits, were usually felt to outweigh the disadvantages, particularly by those in positions of power. Many of the accompanying negative factors, such as poverty and unemployment, or the creation of more destructive machines of war, if they 2.1 Issues of responsibility The aftermath of the 2004 Indian Ocean tsunami saw an unprecedented aid effort to assist the affected regions. In the early days after the disaster, pledges of financial assistance from overseas governments were often outstripped by the generosity of their own populaces. This was a case when ordinary people around the world saw and were moved by the tragic circumstances of others far away (Rose, 2006), and they responded with gifts of money and provisions, and even with offers of their own sk Learning outcomes After studying this course, you should be able to: recognise the interaction of human and physical processes in the making of environments and the understanding of environmental issues understand coastal regions as dynamic and contested environments consider the contested nature of coastal management policies using the case study of managed retreat. 5 Conclusion International economic relationships are constituted in large part by international trade and investment. I have argued that the current trade regime, apparently one of voluntary adherence to negotiated rule-making, is actually systematically weighted against the needs of developing countries. This asymmetry is rooted in a context where rich countries are eager to prescribe free trade for others but reluctant to impose it on themselves and able to avoid doing so. Its consequences are exacerba 3.1.1 Agriculture According to the UR Agreement on Agriculture, import quotas were to be abolished, but since no country was prepared to expose its farmers abruptly to the rigours of free trade, quotas were to be replaced by ‘equivalent’ tariffs, which were to be reduced over time. However, the calculation of equivalent tariffs is subject to wide margins of error, and since it was left to each country to determine its own tariffs, most were set at extraordinarily high levels – exceeding 200 or even 300 p Introduction Free trade or fair trade? This unit will help you to analyse the relationship that exists between developed and developing countries under the World Trade Organization regime of Development Round negotiations. The current world trade regime has a very mixed record in promoting growth and reducing poverty.

In the last 50 years, developments in technology have had a profound effect on the production, recording and manipulation of music. The 8 video tracks in this album introduce Simon Whiteside, a television and film composer, explore his recording studio and explain how he uses MIDI to create music for films and television programmes. Using an example of one of the programmes he has worked on, Simon illustrates the technical and creative processes involved. This material forms part of TA212 Techno
Major retailers today face a major challenge to manage and distribute goods from suppliers around the world. What systems enable big business to keep in touch with latest sales information from their stores? How are Internet and Web technologies and their associated applications used in practice? This album explores how these technologies are changing the way businesses operate internally and externally. The seven video tracks examine a Tesco supply chain and present an insider's view of web ser
