| deposition (The process by which polluting material is precipitated from the atmosphere and accumulates in ecosystems) | jalkitze | |
| deregulation (The removal or relaxation of government control over the economic activities of some commercial entity, industry or economic sector) | desarauketa | |
| dermapteran | dermapteroak | |
| desalination (Removal of salt, as from water or soil) | gatzgabetze | |
| desalination plant (1. Plants for the extraction of fresh water from saltwater by the removal of salts, usually by distilling. 2. Parts of the world with severe water shortages are looking to desalination plants to solve their problems. Desalination of water is still nearly four times more expensive than obtaining water from conventional sources. However technology is improving and costs are likely to decrease slightly in the future. There is now more interest in building distillation plants beside electric installations so that the waste heat from power generation can be used to drive the desalination process) | ura gatzgabetzeko zentral | |
| desert (A wide, open, comparatively barren tract of land with few forms of life and little rainfall) | basamortu | |
| desert (A wide, open, comparatively barren tract of land with few forms of life and little rainfall) | desertu | |
| desert climate (A climate type which is characterized by insufficient moisture to support appreciable plant life; that is, a climate of extreme aridity) | klima basamortutar | |
| desert locust | basamortuko oti | |
| desertification (1. The development of desert conditions as a result of human activity or climatic changes. 2. The process of land damage which allows the soil to spread like a desert in arid and semi-arid regions. There is a loss of vegetative cover and the soil deteriorates in texture, nutrient content and fertility. Desertification affects the lives of three-quarters of the world's population, 70% of all drylands and one quarter of the total land area of the planet. There are many reasons for desertification, but the majority are caused by human activities, overgrazing, deforestation, poor land management and over-exploitation. Agenda 21 states that the priority in combating desertification should be establishing preventive measures for lands that are not yet, or are only slightly, degraded) | desertifikazio | |
| desertification control (Remedial and preventive actions adopted against desertification include irrigation, planting of trees and grasses, the erection of fences to secure sand dunes, and a careful management of water resources) | basamortutzearen kontrol | |
| design (A graphic representation, especially a detailed plan for construction or manufacture; project) | diseinu | |
| desk study (No definition needed) | azterketa teoriko | |
| desorption (The process of removing a sorbed substance by the reverse of adsorption or absorption) | desortzio | |
| destination of transport (The targeted place to which persons, materials or commodities are conveyed over land, water or through the air) | garraioaren norako | |
| desulphurisation (The removal of sulphur, as from molten metals or petroleum oil. Sulphur residues in fuels end up as sulphur dioxide when the fuel is burned causing acid rain) | desulfurazio | |
| desulphurisation of fuel (Removal of sulfur from fossil fuels (or removal of sulfur dioxide from combustion fuel gases) to reduce pollution) | erregaiaren desulfurazio | |
| detection (The act or process of discovering evidence or proof of governmental, legal or ethical violations) | detekzio | |
| detector (A mechanical, electrical, or chemical device that automatically identifies and records or registers a stimulus, such as an environmental change in pressure or temperature, an electrical signal, or radiation from a radioactive material) | detektagailu | |
| detergent (A surface-active agent used for removing dirt and grease from a variety of surfaces and materials. Early detergents contained alkyl sulphonates, which proved resistant to bacterial decomposition, causing foaming in rivers and difficulties in sewage treatment plants. These hard detergents were replaced during the 1960s with soft biodegradable detergents. Apprehension continues to be expressed about the use of phosphates in detergents, helping to promote the process of eutrophication. No satisfactory substitute has yet emerged) | garbigarri |
