| Terms for subject Environment (31552 entries) |
| dégradation des forêts | forest degradation | |
| dégradation des paysages | damage to the countryside | |
| dégradation des polluants | pollutant degradation (The physical, chemical or biological breakdown of a complex polluting material into simpler components) | |
| dégradation des polluants | pollutant degradation | |
| dégradation des qualités récréatives et esthétiques du paysage | degradation of the recreational and aesthetic quality of landscape | |
| dégradation des ressources en eau douce | freshwater degradation | |
| dégradation des ressources en eau douce | freshwater degradation (Pollution immediately or eventually involves the hydrological cycle of the earth, because even pollutants emitted into the air and those present in the soil are washed out by precipitation. Water is considered polluted when it is altered in composition or condition so that it becomes less suitable for any or all of the functions and purposes for which it would be suitable in its natural state. This definition includes changes in the physical, chemical and biological properties of water, or such discharges of liquid, gaseous or solid substances into water as will or are likely to create nuisances or render such water harmful to public health, safety or welfare, or to domestic, commercial, industrial, agricultural, fish or other aquatic life. It also includes changes in temperatures, due to the discharge of hot water) | |
| dégradation des ressources naturelles | degradation of natural resources | |
| dégradation des ressources naturelles | degradation of natural resources (The result of the cumulative activities of farmers, households, and industries, all trying to improve their socio-economic well being. These activities tend to be counterproductive for several reasons. People may not completely understand the long-term consequences of their activities on the natural resource base. The most important ways in which human activity is interfering with the global ecosystem are: 1. fossil fuel burning which may double the atmospheric carbon dioxide concentration by the middle of the next century, as well as further increasing the emissions of sulphur and nitrogen very significantly; 2. expanding agriculture and forestry and the associated use of fertilizers (nitrogen and phosphorous) are significantly altering the natural circulation of these nutrients; 3. increased exploitation of the freshwater system both for irrigation in agriculture and industry and for waste disposal) | |
| dégradation des sols | soil degradation | |
| dégradation des sols | land degradation | |
| dégradation des sols | soil deterioration | |
| dégradation des sols forestiers | land degradation | |
| dégradation des terres | land degradation | |
| dégradation des villes | urban decay | |
| dégradation du capital foncier et forestier | deterioration of land and forest potential | |
| dégradation du paysage | skyline destruction | |
| dégradation du sol | soil degradation (Soil may deteriorate either by physical movement of soil particles from a given site or by depletion of the water-soluble elements in the soil which contribute to the nourishment of crop, plants, grasses, trees, and other economically usable vegetation. The physical movement generally is referred to as erosion. Wind, water, glacial ice, animals and tools in use may be agents of erosion) | |
| dégradation écologique | ecological damage | |
| dégradation en taches | patchy degradation |
