Terms for subject Environment (5582 entries)
deep sea deposit depòsit en fossa marina
deep sea fishing (Fishing in the deepest parts of the sea) pesca marina
deep sea mining (The most valuable of the marine mineral resources is petroleum. About 15% of the world's oil is produced offshore, and extraction capabilities are advancing. One of the largest environmental impacts of deep sea mining are discharged sediment plumes which disperse with ocean currents and thus may negatively influence the marine ecosystem. Coal deposits known as extensions of land deposits , are mined under the sea floor in Japan and England) activitat minera en fons marí
deep-sea disposal (The disposal of solid waste or sludge by carrying the wastes out to sea, usually in a barge, and dumping into deep water) abocament en fons marí
deer (The common name for 41 species of even-toed ungulates that compose the family Cervidae in the order Artiodactyla; males have antlers) cérvol
defence (The act or process of protecting citizens or any geographical area by preparing for or by using military means to resist the attack of an enemy) defensa
defoliation (1. The drop of foliage from plants caused by herbicides such as Agent Orange, diuron, triazines, all of which interfere with photosynthesis. The use of defoliants, as in Vietnam or in jungle clearance for agriculture, can permanently destroy tropical forests. Once the tree cover is removed, the soil is subjected to erosion and precious nutrients are rapidly leached away. 2. Destroying (an area of jungle, forest, etc.) as by chemical sprays or incendiary bombs, in order to give enemy troops or guerilla forces no place of concealment) defoliació
deforestation (The removal of forest and undergrowth to increase the surface of arable land or to use the timber for construction or industrial purposes. Forest and its undergrowth possess a very high water-retaining capacity, inhibiting runoff of rainwater) desforestació
degradability (The capacity of being decomposed chemically or biologically) degradabilitat
degradation (A type of organic chemical reaction in which a compound is converted into a simpler compound in stages) degradació
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) degradació de recursos naturals
degradation of the environment (The process by which the environment is progressively contaminated, overexploited and destroyed) degradació del medi ambient
degradation product (Those chemicals resulting from partial decomposition or chemical breakdown of substances) producte de degradació
degreasing (1. Removing grease from wool with chemicals. 2. Removing grease from hides or skins in tanning by tumbling them in solvents. 3. Removing grease, oil, or fatty material from a metal surface with fumes from a hot solvent) desgreixatge
dehydrated sludge (Sludge whose water content has been reduced by physical means) fang deshidratat
delegated management (The process of assigning or transferring authority, decision making or a specific administrative function from one entity to another) gestió delegada
delinquency delinqüència
delta (A delta is a vast, fan-shaped creation of land, or low-lying plain, formed from successive layers of sediment washed from uplands to the mouth of some rivers, such as the Nile, the Mississippi and the Ganges. 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) delta
demand (The desire, ability and willingness of an individual to purchase a good or service. The consumer must have the funds or the ability to obtain funds in order to convert the desire into demand. The demand of a buyer for a certain good is a schedule of the quantities of that good which the individual would buy at possible alternative prices at a given moment in time) demanda
demesnial water (A body of water that is owned and maintained by a national governmental body or agency) aigua de domini públic
