| rare species (Species which have a restricted world range) | sjelden art | |
| 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) | raster | |
| raster to vector (Methods to convert remotely sensed raster data to vector format. A number of raster-to-vector and vector-to-raster conversion procedures have been developed and introduced to current releases of many GIS packages) | raster til vektor | |
| rate (The amount of change in some quantity during a time interval divided by the length of the time interval) | hastighet | |
| raw material (A crude, unprocessed or partially processed material used as feedstock for a processing operation) | råstoff | |
| raw material consumption (The developed countries depend on a stable supply of raw materials for their industries. Total resource requirements are increasing rapidly over the entire world. In developed countries, although population is increasing slowly, per capita use is increasing rapidly, while the opposite is happening in developing countries. Traditionally raw materials have been classified as non-renewable resources, but a distinction may be important between "loosable" resources, such as oil and coal, and "non-loosable" resources, such as metals, which can be used several times over by recycling processes) | råstofforbruk | |
| raw material securing (Measures used to ensure the provision of or the access to crude, unprocessed or partially processed materials used as feedstock for processing or manufacturing) | råstoffsikring | |
| raw water (Water that has not been treated) | råvann | |
| reaction kinetics (That branch of physical chemistry concerned with the mechanisms and rates of chemical reactions) | reaksjonskinetikk | |
| reactor (A device that introduces either inductive or capacitive reactance into a circuit, such as a coil or capacitor) | reaktor | |
| reactor safety (Those studies and activities that seek to minimise the risk of a nuclear reactor accident) | reaktorsikkerhet | |
| reasonableness | rimelighet | |
| reclamation industry (Industry for the transformation of solid waste into useful products) | gjenvinningsindustri | |
| recombinant DNA technology (Techniques and practical applications associated with recombinant DNA (deoxyribonucleic acid artificially introduced into a cell that alters the genotype and phenotype of the cell and is replicated along with the natural DNA)) | rekombinant DNA-teknikk | |
| recommendation (Recommendation refers to an action which is advisory in nature rather than one having any binding effect) | anbefaling | |
| recording of substances (No definition needed) | stoffregistrering | |
| recovery of landscape (Reclamation measures taken to restore the environmental quality level of a landscape to its predisturbed condition) | landskapsutbedring | |
| recovery plan (A formulated or systematic method for the restoration of natural resources or the reuse of materials and objects) | utbedringsplan | |
| recreation (Activities that promote refreshment of health or spirits by relaxation and enjoyment) | rekreasjon | |
| recreational area (A piece of publicly owned land, especially in a town, used for sports and games) | fritidsområde |
