afvalstortplaats landfill The oldest method of waste disposal for the solid matter discarded in the domestic dustbin, along with the packaging material and paper from high street shops and offices. Landfill sites are usually disused quarries and gravel pits. When they were filled, previous practice was to cover them up with soil and forget about them. Housing estates have been built, often with disastrous consequences, on old landfill dumps. Waste burial has now become a serious technology and a potential source of energy. Landfill sites can be designed to be bioreactors, which deliberately produce methane, gas as a source of biofuel or alternative energy. Traditionally, waste tips remained exposed to air and aerobic microbes - those which thrive in air - in order to turn some of the waste into compost. However, open tips also encourage vermin, smell in hot weather and disfigure the landscape. In the 1960s, as a tidier and safer option, landfill operators began to seal each day's waste in a clay cell. While excluding vermin, the clay also excluded air. Decomposition relied on anaerobic microbes, which die in air. However, the process produced methane (natural gas), which was a safety hazard. The methane is now extracted by sinking a network of perforated pipes into the site. (Source: WRIGHT)

Agenda 21 Agenda 21 Agenda 21, the Rio Declaration on Environment and Development, is a comprehensive programme of action to be achieved by governments, development agencies, United Nations organizations and independent sector groups in every area where human activity affects the environment. Agenda 21 was adopted by the United Nations Conference on Environment and Development, the Earth Summit. Agenda 21 is the response to the UN General Assembly's call, in December 1989, for a global meeting to devise strategies to halt and reverse the effects of environment degradation 'in the context of increased national and international efforts to promote sustainable and environmentally sound development in all countries'.

AIDS AIDS The acquired immunodeficiency syndrome is caused by HIV-virus manifested by opportunistic infections and/or malignancies, and the mortality rate is very high. The syndrome results from a breakdown of the body's disease-fighting mechanism that leaves it defenceless against infections, such as pulmonary tuberculosis, Pneumocystis pneumonia, certain blood infections, candidiasis, invasive cervical cancer, Kaposi's sarcoma or any of over 20 other indicator diseases. No effective treatment is available. A striking feature of AIDS is the wide spectrum and frequency of infections with life-threatening pathogens seldom seen in normal hosts. The illness may begin with insidious signs and symptoms, and the process may be more diffuse than when the same conditions are seen in other immune-compromised patients. Four patterns of disease occur in AIDS patients. The pulmonary pattern, the central nervous system pattern, the gastrointestinal pattern, and the pattern of fever of unknown origin. Most patients who recover from a given opportunistic infection subsequently either have a relapse or develop a new type of infection. Many patients continue to have a wasting syndrome and experience such infections as oral thrush. Feelings of depression and isolation are common among AIDS patients and can be intensified if health care workers display fear of the syndrome. (Source: WPR)

aluminium aluminium A light white metal, ductile and malleable, and a good conductor of electricity. It occurs widely in nature in clays and is the third most abundant element in the Earth's crust. It is extracted mainly from bauxite by electrolysis of a molten mixture of purified bauxite and cryolite. The metal and its alloys are used for aircraft, cooking utensils, electrical apparatus, and for many other purposes where its light weight is an advantage. Aluminium became implicated as an environmental health hazard in the 1980s on two counts.

Asbestos also causes cancer of the lung and the gastro-intestinal tract, and mesothelioma, a malignant cancer of the inner lining of the chest. However, because it is a poor conductor of electricity and highly resistant to heat it has been widely used over the years in fire-fighting suits, and building and insulating materials.

atmosferische inversie atmospheric inversion A temperature inversion in the atmosphere in which the temperature, instead of falling, increases with height above the ground. With the colder and heavier air below, there is no tendency to form upward currents and turbulence is suppressed. Inversions are often formed in the late afternoon when the radiation emitted from the ground exceeds that received from the sinking sun. Inversions are also caused by katabatic winds, that is cold winds flowing down the hillside into a valley, and by anticyclones. In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high level dischargers, hence the case for high stacks. Furthermore, high level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing. (Source: GILP96)

The coral is thought to have formed initially on a flat surface: then as the sea-level rose in post-glacial times, thereby submerging the irregular wave-cut platform, the coral growth kept pace with the rising ocean level, so creating the great thickness witnessed today in such places as the Great Barrier Reef off the East coast of Queensland, Australia. This stretches for more than 1900 km and varies in width from about 30 km to 150 km. (Source: WHIT)

behandeling van gassen treatment of gases Gas is treated before it can be supplied to the marketplace. The extent to which gas needs to be processed will depend on its quality, the amount of associated impurities such as water, carbon dioxide and sulphur compounds, and the ultimate end-use for the gas. Common gaseous impurities found in natural gas are carbon dioxide and sulphur compounds. Both have an acidic reaction and are given the generic name 'acid gases'. These gases can be removed by a number of commercial processes, using either a physical or a chemical solvent. Physical solvent processes tend to be used where gas pressures are high and for gases with lower levels of propane and heavier hydrocarbons. (Source: SHELL)

bodemvervuiler soil pollutant Solid, liquid and gaseous substances that detrimentally alter the natural condition of the soil.
bodemverzilting soil salination The accumulation of soluble mineral salts near the surface of soil, usually caused by the capillary flow of water from saline ground water. Where the rate of surface evaporation is high, irrigation can exacerbate the problem by moistening the soil and causing water to be drawn from deeper levels as water evaporates from the surface. The evaporation of pure water leaves the salts behind, allowing them to accumulate, and they can reach concentrations that are toxic to plants, thus sterilizing the land. (Source: ALL)
bodemverzuring soil acidification A naturally occurring process in humid climates that has long been the subject of research, whose findings suggest acid precipitation effects. The generally accepted impact of soil acidification on the productivity of terrestrial plants is summarised as follows: as soil becomes more acidic the basic cations (Ca, Mg) on the soil exchange are replaced by hydrogen ions or solubilized metals. The basic cation, now in solution, can be leached through the soil. As time progresses the soil becomes less fertile and more acidic. Resultant decreases in soil pH cause reduced, less-active population of soil microorganisms, which in turn slow decomposition of plant residues and cycling of essential plant nutrients.

bodemvocht soil moisture 1) Water stored in soils.2) One of the most important elements involved in pedological processes and plant growth. There are three basic forms: a) water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. b) Water forming thicker films and occupying the smaller pore spaces is termed capillary water. Since it is held against the force of gravity it is permanently available for plant growth and it is this type of soil water which contains plant nutrients in solution. c) Water in excess of hygroscopic and capillary water is termed gravitational water, which is of a transitory nature because it flows away under the influence of gravity. When the excess has drained away the amount of water retained in the soil is termed its field capacity, when some of its pore spaces are still free of water. (Source: LANDY / DUNSTE)
bodemvochthuishouding soil moisture regime The water regime of the soil is determined by the physical properties and arrangement of the soil particles. The pores in a soil determine its water-retention characteristics. When all the pores are full of water, the soil is said to be saturated. (Source: DUNSTE)
bodemvorming soil formation The combination of natural processes by which soils are formed. It is also known as pedogenesis. The most important soil-forming factors are parent material, terrain, climate, aspect, vegetation cover, microorganisms in the soil and the age of the land surface. Some pedologists would add to this list the influence of human activities. All the factors exhibit varying degrees of interrelationship and some are more important than others, with climate often being singled out as the most important. (Source: WHIT)

cesium caesium A soft silvery-white and highly reactive metal belonging to the alkali group of metals. It is a radiation hazard, because it can occur in two radioactive forms. Caesium-134 is produced in nuclear reactors, not directly by fission, but by the reaction. It emits beta- and gamma-radiation and has a half-life of 2.06 years. Caesium-137 is a fission product of uranium and occurs in the fallout from nuclear weapons. It emits beta- and gamma-rays and has a half-life of 30 years. Caesium-137 was the principal product released into the atmosphere, and hence the food chain, from atmospheric testing of nuclear weapons and from the Windscale fire and Chernobyl nuclear accidents.

chloor chlorine A very reactive and highly toxic green, gaseous element, belonging to the halogen family of substances. It is one of the most widespread elements, as it occurs naturally in sea-water, salt lakes and underground deposits, but usually occurs in a safe form as common salt (NaCl). Commercially it is used in large quantities by the chemical industry both as an element to produce chlorinated organic solvents, like polychlorinated biphenyls (PCBs), and for the manufacture of polyvinyl chloride plastics, thermoplastic and hypochlorite bleaches. Chlorine was the basis for the organochlorine pesticides, like DDT and other agricultural chemicals that have killed wildlife. The reactivity of chlorine has proved disastrous for the ozone layer and has been the cause of the creation of the ozone hole, which was first detected in the Southern Hemisphere over Antarctica and then over the Northern Hemisphere.

In insects and other animals these compounds act primarily on the central nervous system. They also become concentrated in the fats of organisms and thus tend to produce fatty infiltration of the heart and fatty degeneration of the liver in vertebrates. In fishes they have the effect of preventing oxygen uptake, causing suffocation. They are also known to slow the rate of photosynthesis in plants. Their danger to the ecosystem resides in their rate stability and the fact that they are broad-spectrum poisons which are very mobile because of their propensity to stick to dust particles and evaporate with water into the atmosphere.

The principal outcomes of the Summit were a declaration, conventions on controlling climate change and preserving biological diversity, and a lengthy agenda outlining the extent of global environmental problems and the measures needed to tackle them in order to achieve the agreed goal of 'sustainable development'. Opinion was divided as to how far the conference could be termed a success. Many environmentalists stressed its failure to set binding targets for resolving environmental problems, and to address adequately the links between third world poverty and environmental degradation. Others, such as many of the world leaders who attended the conference stressed that it should be seen as a first step towards sustainable development, and an important acknowledgment of the seriousness of the problem and of the fact that global co-operation is needed to overcome it.

de invloed van veranderingen in het klimaat climatic effect Climate has a central influence on many human needs and activities, such as agriculture, housing, human health, water resources, and energy use. The influence of climate on vegetation and soil type is so strong that the earliest climate classification schemes where often based more on these factors than on the meteorological variables. While technology can be used to mitigate the effects of unfavorable climatic conditions, climate fluctuations that result in significant departures from normal cause serious problems for modern industrialized societies as much as for primitive ones. The goals of climatology are to provide a comprehensive description of the Earth's climate, to understand its features in terms of fundamental physical principles, and to develop models of the Earth's climate that will allow the prediction of future changes that may result from natural and human causes.

The nutrient-rich sediment is deposited by rivers at the point where, or before which, the river flows into the sea. Deltas are formed when rivers supply and deposit sediments more quickly that they can be removed by waves of ocean currents. The importance of deltas was first discovered by prehistoric man, who was attracted to them because of their abundant animal and plant life. Connecting waterways through the deltas later provided natural routes for navigation and trade, and opened up access to the interior. Deltas are highly fertile and often highly populated areas. They would be under serious threat of flooding from any sea-level rise. (Source: WRIGHT)

divers product miscellaneous product
DNA DNA The principal material of inheritance. It is found in chromosomes and consists of molecules that are long unbranched chains made up of many nucleotides. Each nucleotide is a combination of phosphoric acid, the monosaccharide deoxyribose and one of four nitrogenous bases: thymine, cytosine, adenine or guanine. The number of possible arrangements of nucleotides along the DNA chain is immense. Usually two DNA strands are linked together in parallel by specific base-pairing and are helically coiled. Replication of DNA molecules is accomplished by separation of the two strands, followed by the building up of matching strands by means of base-pairing, using the two halves as templates. By a mechanism involving RNA, the structure of DNA is translated into the structure of proteins during their synthesis from amino acids. (Source: ALL)

EG-milieukeur(merk) EC ecolabel The European Community (EC) initiative to encourage the promotion of environmentally friendly products. The scheme came into operation in late 1992 and was designed to identify products which are less harmful to the environment than equivalent brands. For example, eco-labels will be awarded to products that do not contain chlorofluorocarbons (CFCs) which damage ozone layer, to those products that can be, or are, recycled, and to those that are energy efficient. The labels are awarded on environmental criteria set by the EC. These cover the whole life cycle of a product, from the extraction of raw materials, through manufacture, distribution, use and disposal of the product. The first products to carry the EC eco-labels were washing machines, paper towels, writing paper, light bulbs and hairsprays. (Source: WRIGHT)

emissietoestand emission situation
emissievoorspelling emission forecast The final step in a clean air plan is to predict future air quality to demonstrate that we can (if we can) meet the health standards by implementing the measures proposed in the plan. This is done by first projecting the emission inventory into the future, taking into account changes in population, housing, employment in specific business sectors, and vehicle miles traveled. These data are obtained from various sources and the resulting emissions are adjusted to account for regulations and control measures scheduled for implementation during the same time period. Additional adjustments are made to reflect large facilities that are expected to start up, modify, or shut down. The resulting inventory is an emission forecast, and is usually expressed in tons per day of particular pollutants for a given year. Additional steps may be required to determine how the forecasted quantities of air pollution will affect the overall air quality. One way to accomplish this is through computer modeling. A computer model simulates how pollutants disperse, react, and move in the air. The inputs to such a computer model are complex. They include weather patterns, terrain, and the chemical nature of air pollutants. (Source: APCD)

Europees Milieuagentschap European Environment Agency The EEA is being set up to provide the European Community and its member states with objective, reliable and standardized information on the environment. It will assess the success of existing environmental policies and the data will be used to develop new policies for environmental protection measures. It will gather information covering the present, and foreseeable, state of the environment. The priority area are: air quality and emissions; water quality, pollutants and resources; soil quality, flora and fauna, and biotopes; land use and natural resources; waste management; noise pollution; chemicals; and protection of coastal areas. The Agency will also take into account the socio-economics dimension, cover transboundary and international matters, and avoid the duplication of the activities of other bodies. (Source: WRIGHT)

eutrofiëring eutrophication A process of pollution that occurs when a lake or stream becomes over-rich in plant nutrient; as a consequence it becomes overgrown in algae and other aquatic plants. The plants die and decompose. In decomposing the plants rob the water of oxygen and the lake, river or stream becomes lifeless. Nitrate fertilizers which drain from the fields, nutrients from animal wastes and human sewage are the primary causes of eutrophication. They have high biological oxygen demand (BOD).

genenbank gene bank Storehouses of seeds or vegetative tissue, kept in low humidity and temperature, to help maintain genetic diversity. Sometimes known as seed banks or germ plasm banks. their contents mostly originate from a wide range of primitive strains and wild crop varieties. The International Board for Plant Genetic Resources (IBPGR), which was established in 1974, promotes the collection, documentation, evaluation, conservation and eventual use of genetic resources of significant plant species. Gene banks are the subject of international controversy because they contain seeds that have mostly been acquired from the developing countries by the industrially rich countries, where they have been used in breeding programmes to develop new strains. Instead of taking decades over a traditional plant breeding programme by fertilization, it is now possible to manipulate directly the genes of plants, creating genetically modified organisms (GMOs), which are plants modified to give a higher resistance to disease and improved growth and yields and, therefore, increase the profit of the plant breeder and farmer.

The values of various inputs of the model are then varied and the resultant change in the output variable is monitored. Large changes in the output variable imply that the particular input varied is important in controlling model behaviour. Within this general definition, sensitivity analysis has been applied to a variety of model inputs including state variables, environmental variables and initial conditions. (Source: YOUNG)

gewasbescherming crop protection The problem of crop protection has changed dramatically since 1945. There is now a whole arsenal of chemicals with which to combat agricultural pests and diseases, but this development has itself many drawbacks. Such sophisticated techniques are available only to a minority of farmers; in most parts of the world the standard of crop protection remains abysmally low. In addition, modern crop protection methods have been criticized for relying too heavily on chemical control. Biological controls, both natural and contrived, have been neglected. In some cases involving misuse of agricultural chemicals, crops must be protected from the very measures intended for their protection. Meanwhile previously localized pests and diseases continue to spread worldwide. (Source: WPR)

grensvlak tussen het oceaanwater en de lucht ocean-air interface The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water. (Source: PARCOR)

invloed van energie op het milieu environmental impact of energy Energy and environmental problems are closely related, since it is nearly impossible to produce, transport, or consume energy without significant environmental impact. The environmental problems directly related to energy production and consumption include air pollution, water pollution, thermal pollution, and solid waste disposal. The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Diverse water pollution problems are associated with energy usage. One major problem is oil spills. In all petroleum-handling operations, there is a finite probability of spilling oil either on the earth or in a body of water. Coal mining can also pollute water. Changes in groundwater flow produced by mining operations often bring otherwise unpolluted waters into contact with certain mineral materials which are leached from the soil and produce an acid mine drainage. Solid waste is also a by-product of some forms of energy usage. Coal mining requires the removal of large quantities of earth as well as coal. In general, environmental problems increase with energy use and this combined with the limited energy resource base is the crux of the energy crisis. An energy impact assessment should compare these costs with the benefits to be derived from energy use. (Source: RAU)

Improper application of fertilizers has changed the types of vegetation and fish types inhabiting nearby waterways and rivers. (Source: RAU / WPR)
invloed van recreatie op het milieu environmental impact of recreation Recreation and tourism are often accompanied by extensive damage to the environment. Aquatic ecosystems are particularly vulnerable to the effects of an increased tourist trade and the resultant building of hotel accommodations, sewage disposal works, roads, car parks and landing jetties on banks and coastlines; and the increased angling, swimming, water skiing, shooting or use of motor-boats in the water body. These all produce direct deleterious effects when conducted on a massive scale, including shore damage, chemical changes in the water, and sediments and biological changes in the plant and animal communities.

invloed van visserij op het milieu environmental impact of fishing Fishing may have various negative effects on the environment: effluent and waste from fish farms may damage wild fish, seals, and shellfish. Fish farmers use tiny quantities of highly toxic chemicals to kill lice: one overdose could be devastating. So-called by-catches, or the incidental taking of non-commercial species in drift nets, trawling operations and long line fishing is responsible for the death of large marine animals and one factor in the threatened extinction of some species. Some fishing techniques, like the drift nets, yield not only tons of fish but kill millions of birds, whales and seals and catch millions of fish not intended. Small net holes often capture juvenile fish who never have a chance to reproduce. Some forms of equipment destroy natural habitats, for example bottom trawling may destroy natural reefs. Other destructive techniques are illegal dynamite and cyanide fishing. (Source: WPR)

Cockroaches are usually found in tropical climates, but a few species, out of the total 3.500 known species, have become pests. They are common household pests in many countries, imported by ship and carried home in grocery bags. Cockroaches eat plant and animal products, including food, paper, clothing and soiled hospital waste, fouling everything they touch with their droppings and unpleasant odour, to which many people are allergic. They are a major health hazard and carry harmful bacteria, protozoan parasites and faunal pathogens, including those that cause typhoid, leprosy and salmonella. Conventional insecticides make little or no impact on the cockroaches population. (Source: WRIGHT / WPR)

kernbrandstof nuclear fuel Nuclear fuels are obtained from inorganic minerals extracted by mining. Although they are at least partially consumed when used in nuclear reactors for the production of heat, they differ from fossil fuels in the way they release energy. Burning of fossil fuels, such as coal, oil and gas, is a chemical reaction. Nuclear fuels, such as uranium, are destroyed by a process of spontaneous disintegration, called fission, and prompted by natural radioactivity. If the process is left to occur naturally in uranium-bearing rock, the rate of change is imperceptibly small. In a man-made nuclear reactor the energy-releasing processes of disintegration, which in the natural state happen slowly over thousands of millions of years, are compressed into minutes. The release of energy is harnessed to generate steam which drives electricity generators. (Source: WRIGHT)

klimaat climate The average weather condition in a region of the world. Many aspects of the Earth's geography affect the climate. Equatorial, or low, latitudes are hotter than the polar latitudes because of the angle at which the rays of sunlight arrive at the Earth's surface. The difference in temperature at the equator and at the poles has an influence on the global circulation of huge masses of air. Cool air at the poles sinks and spreads along the surface of the Earth towards the equator. Cool air forces its way under the lower density warmer air in the lower regions, pushing the lighter air up and toward the poles, where it will cool and descend. (Source: WRIGHT)

Lead exposure may be due to air, water, food, or soil. Lead in the air is primarily due to lead-based fuels and the combustion of solid waste, coal, oils, and emissions from alkyl lead manufacturers, wind blown dust volcanoes, the burning of lead-painted surfaces, and cigarette smoke. Lead in drinking water comes from leaching from lead pipes, connectors, and solder in both the distribution system and household plumbing. (Source: KOREN)

marktgewas cash crop Crops that are grown for sale in the town markets or for export. They include coffee, cocoa, sugar, vegetables, peanuts and non-foods, like tobacco and cotton. Huge areas of countries in the developing world have been turned over to cash crops. Those countries with no mineral or oil resources depend on cash crops for foreign money, so that they can import materials do develop roads, for construction, or to buy Western consumer goods and, indeed, food. However, critics argue that cash crops are planted on land that would otherwise be used to grow food for the local community and say this is a cause of world famine. Cash crops, such as peanuts, can ruin the land if it is not left fallow after six years of harvests. Moreover, if the best agricultural land is used for cash crops, local farmers are forced to use marginal land to grow food for local consumption, and this has a further dramatic effect on the environment.

mutatie mutation A change in the chemical constitution of the DNA in the chromosomes of an organism: the changes are normally restricted to individual genes, but occasionally involve serious alteration to whole chromosomes. When a mutation occurs in gametes or gametocytes an inherited change may be produced in the characteristics of the organisms that develop from them. Mutation is one of the ways in which genetic variation is produced in organisms. A somatic mutation is one that occurs to a body cell, and is consequently past on to all the cells derived from it by mitosis. Natural mutations, at this stage of biological evolution, when they occur in the cells of higher animals, almost always produce deleterious characteristics. Both natural and artificial mutations can be brought about by ionizing radiation (hence the genetic and carcinogenic dangers of nuclear weapons) and by certain chemical substances called mutagens.

natuurreservaat nature reserve Areas allocated to preserve and protect certain animals and plants, or both. They differ from national park, which are largely a place for public recreation, because they are provided exclusively to protect species for their own sake. Endangered species are increasingly being kept in nature reserves to prevent them from extinction, particularly in India, Indonesia and some African countries. Natural reserves were used once to preserve the animals that landowners hunted, but, in the 19th century, they became places where animals were kept to prevent them from dying out. Special refuges and sanctuaries are also often designated to protect certain species or groups of wild animals or plants, especially if their numbers and distribution have been significantly reduced. They also serve as a place for more plentiful species to rest, breed or winter. Many parts of the world also have marine and aquatic reserves to protect different species of sea or freshwater plant and animal life. (Source: WRIGHT)

oestercultuur oyster farming There are two types of oyster farming: suspension culture, in which oysters are grown off bottom, in floating trays, is a labor-intensive form of cultivation that requires continuous tending and cleaning of both gear and shellfish, and bottom culture, which is similar to conventional crop farming on land; it involves selecting areas of the sea floor that provide a natural food supply, necessary currents, minimum exposure to predators, and proper temperature and then 'seeding' the bottom with shellfish stock that are left to grow to market size. Then they are harvested with a bottom drag from a boat. Both suspension culture and bottom culture depend on natural food supplies for growing the shellfish being raised. (Source: MSTF)

olieproductie oil production (chain) The petroleum industry is a complex industry utilizing complex combination of interdependent operations engaged in the storage and transportation, separation of crude molecular constituents, molecular cracking, molecular rebuilding and solvent finishing to produce petrochemical products. Treatment may involve oil separation, precipitation, adsorption, and biological treatment. The refining operations can be divided into four major steps: separation, conversion, treating, and blending. The crude oil is first separated into selected fractions (gasoline, kerosine, fuel oil, etc.). Some of the less valuable products such as heavy naphtha, are converted to products with a greater sale value such as gasoline. The final step is the blending of the refined base stocks with each other and various additive to meet final product specifications. The major pollutants emitted are sulphur oxides, nitrogen oxides, hydrocarbons, carbon monoxide, and malodorous materials. (Source: PZ)

It is often done without factors such as climate and topography having been sufficiently studied and on lands where slope nature of the soil or other physiographic characteristics clearly indicate that the land involved is suitable only for forest. Although these practices may lead to a temporary increase in productivity, there are also many indications that in the long run there is usually a decrease in productivity per unit of surface and that erosion and irreversible soil deterioration often accompany this process. Many factors contribute to forest cover destruction: timber production, clearance for agriculture, cutting for firewood and charcoal, fires, droughts, strip mining, pollution, urban development, population pressures, and warfare.

opgeloste zuurstof dissolved oxygen The amount of oxygen dissolved in a stream, river or lake is an indication of the degree of health of the stream and its ability to support a balanced aquatic ecosystem. The oxygen comes from the atmosphere by solution and from photosynthesis of water plants. The maximum amount of oxygen that can be held in solution in a stream is termed the saturation concentration and, as it is a function of temperature, the greater the temperature, the less the saturation amount. The discharge of an organic waste to a stream imposes an oxygen demand on the stream. If there is an excessive amount of organic matter, the oxidation of waste by microorganisms will consume oxygen more rapidly than it can be replenished. When this happens, the dissolved oxygen is depleted and results in the death of the higher forms of life. (Source: PORT)

organisch gebonden stikstof organic nitrogen Essential nutrient of the food supply of plants and the diets of animals. Animals obtain it in nitrogen-containing compounds, particularly aminoacids. Although the atmosphere is nearly 80% gaseous nitrogen, very few organisms have the ability to use it in this form. The higher plants normally obtain it from the soil after microorganisms have converted the nitrogen into ammonia or nitrates, which they can then absorb. This conversion of nitrogen, known as nitrogen fixation, is essential for the formation of amino acids which, in turn, are the building blocks of proteins. (Source: WRIGHT)

osmose osmosis The passage of a solvent through a semipermeable membrane separating two solutions of different concentrations. A semipermeable membrane is one through which the molecules of a solvent can pass but the molecules of most solutes cannot. There is a thermodynamic tendency for solutions separated by such a membrane to become equal in concentration, the water (or other solvent) flowing from the weaker to the stronger solution. Osmosis will stop when the two solutions reach equal concentration, and can also be stopped by applying a pressure to the liquid on the stronger-solution side of the membrane. The pressure required to stop the flow from a pure solvent into a solution is a characteristic of the solution, and is called the osmotic pressure. Osmotic pressure depends only on the concentration of particles in the solution, not on their nature. (Source: DICCHE)

oude afzetting old landfill site Landfill that has been filled and covered with topsoil and seeded. The most common end use for landfills is open spaces with no active recreation taking place over the completed landfill. The obvious reason for this use is that the completed surface is steeply sloped to provide rapid runoff. Also, no irrigation of the cover grasses should be allowed. It is very unlikely to think that commercial or industrial buildings will be constructed on a completed landfill. If the end use is such that the public will be walking on the site, it is important that all manholes be properly secured, leachate lagoons fenced, and other potential hazards eliminated.

overbeweiding overgrazing Intensive grazing by animals, for example cattle, sheep or goats, on an area of pasture. It has become a serious threat to the world's rangelands and grasslands. Several factors have led to overgrazing, which leads to the soil being degraded and becoming liable to erosion by wind and rain, and even to desertification. The main pressures leading to widespread overgrazing have been the need to increase the size and numbers of herds to produce more food for an increasing human population, and the transformation of traditional pasture land into plantations to grow cash crops. Throughout the dry tropics, where traditionally herds ranged over vast areas, intensive livestock-rearing schemes have taken over, mostly to provide meat for the export market. Well-digging operations have also led to heavy concentrations of animals in small areas. (Source: WRIGHT)

polybroombifenyl polybrominated biphenyl A chemical substance the composition of which, without regard to impurities, consists of brominated biphenyl molecules. (Source: KOREN)
polychloorbifenyl 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)

posidonia (soort schaaldier) posidonia Plant with elongated, planar, green leaves which measure up to 1,5 m. The flowers come out in the autumn but not every year. The fruits are dark balls, which one often finds washed up on beaches after storms. The same happens with the leaves which wilt and separate from the plant at the end of summer. It grows on sandy substrates, and has a rhizome from which several plants grow. The compact form of its growths retains the sediments pulled by the currents along the sea bed. Neptunegrass forms extensive prairies, always on the continental shelf. The plant's presence, apart from constituting an excellent refuge and food reserve for many species, gives an indication of the maturity and good condition of the whole marine ecosystem.

rapporteringsproces reporting process
raster raster One of the two major types of internal data organization used in GIS. Raster systems superimpose a regular grid over the area of interest and associate each cell-or pixel, to use the image term- with one or more data records. The values associated with each grid cell may represent either real values or any scalar or nominal data values associated with the cell coordinates. Among the strengths of the raster method is its ability to accept data directly from remote sensing systems and to represent transitional information. Raster systems tend to be relatively storage-intensive and this imposes practical limits on the area of coverage, the resolution, or both of these. Capacity constraints are, however, becoming less significant as computer memory and storage become more powerful and as data compression techniques become more readily available. (Source: YOUNG)

A study financed by UNEP, reporting in 1992, found that about 10,5% of the world's vegetative surface had been seriously damaged by human activity since 1945. The study found that much of the damage had been masked by a general rise in global agricultural productivity resulting from expanded irrigation, better plant varieties, and greater use of production inputs, such as fertilizers and pesticides. More than 1/3 of the damaged land was in Asia, almost 1/3 in Africa, and 1/4 in Central America. Some land had been damaged beyond restoration. The greatest sources of soil degradation were overgrazing, unsuitable agricultural practices, and deforestation. (Source: GILP96)
