ecosystem degradation
Degradation or destruction of large natural environments. When one ecosystem is under attack as a result of natural or man-made disaster it is extremely difficult to calculate the ripple effects throughout nature. When two or more ecosystems are being degraded the probabilities of synergistic destructiveness multiply. Ecosystems in many regions are threatened, despite their biological richness and their promise of material benefits. (Source: WPR)

polychlorinated biphenyl
PCBs are a family of chemical compounds which do not exist in nature but which are man-made. Commercial mixtures are clear, pale yellow liquids, manufactured by the replacement of hydrogen atoms on the biphenyl molecule by chlorine. Because of their physical properties, PCBs are commonly found in electrical equipment which requires dielectric fluid such as power transformers and capacitors, as well as in hydraulic machinery, vacuum pumps, compressors and heat-exchanger fluids. Other uses include: lubricants, fluorescent light ballasts, paints, glues, waxes, carbonless copy paper, inks including newspapers, dust-control agents for dirt roads, solvents for spreading insecticides, cutting oils. PCBs are stable compounds and although they are no longer manufactured they are extremely persistent and remain in huge quantities in the atmosphere and in landfill sites. They are not water-soluble and float on the surface of water where they are eaten by aquatic animals and so enter the food chain. PCBs are fat-soluble, and are therefore easy to take into the system, but difficult to excrete. (Source: PZ / PHC)

appropriate technology
1) A flexible and participatory approach to developing economically viable, regionally applicable and sustainable technology.
2) Technology designed to be used in developing countries. Typical requirements are that it should: be easy to use by the unskilled; have no difficult-to-get parts; be easily repaired on the spot. Typical example: a simple windmill to pump water rather than a diesel-driven pump. The terms `alternative', `intermediate' and `appropriate' are often used interchangeably.

reverse osmosis
A method of obtaining pure water from water containing a salt, as in desalination. Pure water and the salt water are separated by a semipermeable membrane and the pressure of the salt water is raised above the osmotic pressure, causing water from the brine to pass through the membrane into the pure water. This process requires a pressure of some 25 atmospheres, which makes it difficult to apply on a large scale. (Source: DICCHE)

environmental economics
A recognized field of specialization in the discipline of Economics that embraces the issues of pollution control and environment protection, in which costs and benefits are difficult or impossible to estimate, much of the subject matter falling outside the competitive market system. Yet, it is an area in which immense common property resources need to be allocated sensibly to the overall public good. The subject is also very much concerned with ways and means to achieve this sensible allocation such as emission and effluent charges, user charges for the treatment or disposal of waste, environmental taxes, product charges, deposit refunds, tradeable pollution rights, performance bonds, natural resource accounting, and the economic implications of sustainable development.
