| green manure (Herbaceous plant material plowed into the soil while still green) | سماد أخضر | |
| green revolution (The name given to the widespread development of high-yield strains of wheat, corn and rice during the 1960s and early 1970s. It was more formally known as the Indicative World Plan for Agricultural Development. The revolution came after the Food and Agricultural Organization held the World Food Congress in 1963. A "Freedom from Hunger" campaign was set up with the goal of increasing food supplies and solving the world's hunger problems) | الثورة الخضراء | |
| green space (A plot of vegetated land separating or surrounding areas of intensive residential or industrial use and devoted to recreation or park uses) | مساحة خضراء | |
| green tide (A proliferation of a marine green plankton toxic and often fatal to fish, perhaps stimulated by the addition of nutrients) | المد الأخضر | |
| green vegetable (A vegetable having the edible parts rich in chlorophyll and forming an important source of vitamins and micronutrients) | خضراوات خضراء | |
| greenbelt (1. An area of land, not necessarily continuous, near to and sometimes surrounding a large built-up area. The area is kept open by permanent and severe restriction on building. 2. An irrigated, landscaped, and regularly maintained fuelbreak, usually put to some additional use, such as a golf course, park, or playground. 3. A planning designation that mandates the setting aside of otherwise developable lands for the purpose of creating natural or semi-natural open spaces. Greenbelts are usually linear parkways, tracts, or belts of land running through or around urban conurbations. 4. An area or zone of open, semi-rural, low-density land surrounding existing major urban areas, but not necessarily continuous. The zone is to be kept open by permanent and severe restrictions on new development) | الحزام الأخضر | |
| greenbelt | حِزام اخضر | |
| greenhouse cultivation (Cultivation of plants, especially of out-of-season plants, in glass-enclosed, climate-controlled structures) | زراعة الصُوَب | |
| greenhouse effect (The warming of the Earth's atmosphere caused by the increasing concentration of atmospheric gases, such as water vapour and carbon dioxide. These gases absorb radiation emitted by the Earth, thus slowing down the loss of radiant energy from the Earth back to space) | ظاهرة الاحتباس الحراري | |
| greenhouse gas (A collective expression for those components of the atmosphere that influence the greenhouse effect, namely carbon dioxide, methane, nitrous oxides, ozone, CFCs and water vapour, GHG) | غاز مسبب للاحتباس الحراري | |
| greenhouse gas sink | مصارف الغازات المسببة للاحتباس الحرارى | |
| greenhouse sink | مصارف الغازات المسببة للاحتباس الحرارى | |
| gridding (A system of uniformly spaced perpendicular lines and horizontal lines running north and south, and east and west on a map, chart, or aerial photograph; used in locating points) | التقسيم إلى مربعات | |
| grinding (To reduce to powder or small fragments) | سحق - طحن | |
| gross domestic product (The total output of goods and services produced by a national economy in a given period, usually a year, valued at market prices. It is gross, since no allowance is made, for the value of replacement capital goods) | الناتج الإجمالي المحلي | |
| gross national product (Gross domestic product adjusted for foreign transactions, i.e. to the figure for Gross Domestic Product must be added any income accruing to residents of the country arising from investment and other factor earnings abroad and from it must be deducted any income earned in the domestic market by factors owned by foreigners abroad) | الناتج الإجمالي المحلي | |
| groundwater (Water that occupies pores and crevices in rock and soil, below the surface and above a layer of impermeable material. It is free to move gravitationally, either downwards towards the impermeable layer or by following a gradient) | مياه جوفية | |
| groundwater endangering (Threat to the quality and quantity of groundwater by activities related to the use of land. As some activities (e.g. landfill) present a particular risk of pollution, the closer an activity is to a well or borehole, the greater the risk of the pumped water being polluted. The type of soil, the geology, the rainfall and the amount of water pumped out of the ground must all be taken into consideration) | تهديد المياه الجوفية | |
| groundwater extraction (The process, deliberate or inadvertent, of extracting ground water from a source at a rate so in excess of the replenishment that the ground water level declines persistently, threatening exhaustion of the supply or at least a decline of pumping levels to uneconomic depths) | استخراج المياه الجوفية | |
| groundwater pollution (Contamination of any water found under the earth's surface by any leaching pollutants, such as inorganic compounds (chlorides, nitrates, heavy metals, etc.), synthetic organic chemicals (pesticides, fertilizers, etc.) and pathogens (bacteria, parasites, etc.)) | تلوث المياه الجوفية |
