| land use planning (The interdisciplinary process of evaluating, organising, and controlling the present and the future development and use of lands and their resources in terms of their suitability on sustained yield basis. Includes an overall ecological evaluation in terms of specific kinds of uses as well as evaluations of social, economic, and physical contexts to the land concerned) | zemes lietošanas plānošana | |
| land use regime (Relation existing between the landowner and the tenant farmer who cultivates the land) | zemes izmantošanas režīms | |
| land value (The monetary or material worth in commerce or trade of an area of ground considered as property) | zemes vērtība | |
| land-based activity | sauszemes saimnieciskā darbība | |
| land-based marine pollution | sauszemes saimnieciskās darbības izraisīts jūras piesārņojums | |
| land-management intervention area (Any expanse of land which requires a person or agency with authority to interpose or interfere in how it is used or administrated) | zemes resursu apsaimniekošanas intervences zona | |

| landfill | apglabāšana poligonā | |
| landfill (The oldest method of waste disposal for the solid matter discarded in the domestic dustbin, along with the packaging material and paper from high street shops and offices. Landfill sites are usually disused quarries and gravel pits. When they were filled, previous practice was to cover them up with soil and forget about them. Housing estates have been built, often with disastrous consequences, on old landfill dumps. Waste burial has now become a serious technology and a potential source of energy. Landfill sites can be designed to be bioreactors, which deliberately produce methane, gas as a source of biofuel or alternative energy. Traditionally, waste tips remained exposed to air and aerobic microbes - those which thrive in air - in order to turn some of the waste into compost. However, open tips also encourage vermin, smell in hot weather and disfigure the landscape. In the 1960s, as a tidier and safer option, landfill operators began to seal each day's waste in a clay cell. While excluding vermin, the clay also excluded air. Decomposition relied on anaerobic microbes, which die in air. However, the process produced methane (natural gas), which was a safety hazard. The methane is now extracted by sinking a network of perforated pipes into the site) | pildizgāztuve | |
| landfill base sealing (Sealing of a landfill with a relatively impermeable barrier designed to keep leachate inside. Liner materials include plastic and dense clay) | pildizgāztuves hidroizolācija | |
| landfill covering (The protective shielding, consisting of soil or some other material, that encloses disposal sites for compacted, non-hazardous solid waste, or secures disposal sites for hazardous waste to minimize the chance of releasing hazardous substances into the environment) | pildizgāztuves segums | |
| landfill degasification (Landfill gas is highly dangerous as methane is highly explosive; therefore it must be controlled at all operational landfill sites, whether by active or passive ventilation or both especially in the case of deep sites. There exist venting systems for shallow and deep sites respectively) | pildizgāztuves atgāzēšana | |
| landfill gas | atkritumu gāze | |
| landfill gas (Landfill gas is generated in landfill sites by the anaerobic decomposition of domestic refuse (municipal solid waste). It consists of a mixture of gases and is colourless with an offensive odour due to the traces of organosulphur compounds. Aside for its unpleasantness, it is highly dangerous as methane is explosive in concentrations in air between 5 per cent, the Lower Explosive Limit (LEL), and the Upper Explosive Limit (UEL) of 15 per cent. Landfill gas must be controlled at all operational landfill sites, whether actively or passively vented or both especially in the case of deep sites) | pildizgāztuves gāze | |
| landfill leachate (Liquid that has seeped through solid waste in a landfill and has extracted soluble dissolved or suspended materials in the process) | pildizgāztuves notekūdeņi | |
| landform (Any physical, recognizable form or feature of the Earth's surface, having a characteristic shape and produced by natural causes; it includes major forms such as plane, plateau and mountain, and minor forms such as hill, valley, slope, esker, and dune. Taken together the landforms make up the surface configuration of the Earth's) | reljefs | |
| landliving animal | sauszemes dzīvnieks | |
| landscape (The traits, patterns, and structure of a specific geographic area, including its biological composition, its physical environment, and its anthropogenic or social patterns. An area where interacting ecosystems are grouped and repeated in similar form) | ainava | |
| landscape after mining (The process of mining disfigures the surface of the land, and in the absence of reclamation leads to permanent scars. The process spoils the vital topsoil, disrupts drainage patterns, destroys the productive capacity of agricultural and forest land and impairs their aesthetic and social value) | ainava pēc izrakteņu ieguves | |
| landscape alteration (Landscapes might change through time as a result of human activities or natural processes such as fires or natural disasters. Changes in landscape structure can be documented by using data from aerial photographs or satellite images, and new technologies, such as remote sensing and geographic information systems) | ainavas pārveidošana |
