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) |

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) |

flaring (1. Flares use open flames during normal and/or emergency operations to combust hazardous gaseous. The system has no special features to control temperature or time of combustion; however, supplemental fuel may be required to sustain the combustion. Historically, flares have been used to dispose of waste gases in the oil and gas industry and at wastewater treatment plants having anaerobic digestors. Regulation for thermal destruction of hazardous wastes limit the practical use of flaring to combustion of relatively simple hydrocarbons, such as methane from digesters or landfill gas collection systems. 2. A control device that burns hazardous materials to prevent their release into the environment; may operate continuously or intermittently, usually on top a stack) |

| degassificazione di discarica |
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) |
