| Terms for subject Environment (6407 entries) |
| demonstrability (No definition needed) | frogagarritasun | |
| dendrochronology (The science of dating the age of a tree by studying annual growth rings. It is also employed to interpret previous environments and climatic variations by examining certain kinds of trees. It is based on the theory that the width of the growth ring reflects the amount of rainfall and the temperature of the year in which it was formed) | dendrokronologia | |
| dendrometry (The measuring of the diameter of standing trees from the ground with a dendrometer that can also be used to measure tree heights) | dendrometria | |
| denitrification (1. The loss of nitrogen from soil by biological or chemical means. It is a gaseous loss, unrelated to loss by physical processes such as through leachates. 2. The breakdown of nitrates by soil bacteria, resulting in the release of free nitrogen. This process takes place under anaerobic conditions, such as are found in water-logged soil, and it reduces soil fertility) | desnitrifikazio | |
| denitrification of waste gas (Current methods for controlling NOx emissions in motor vehicles include retardation of spark timing, increasing the air/fuel ratio, injecting water into the cylinders, decreasing the compression ratio, and recirculating exhaust gas. For stationary sources, one abatement method is to use a lower NOx producing fuel or to modify the combustion process by injecting steam into the combustion chamber) | hondar-gasen desnitrifikazio | |
| density (The mass of unit volume of a substance) | dentsitate | |
| deposited particulate matter | jalkitako partikulak | |
| deposited particulate matter | jaliktako zatikiak | |
| 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 |
