NIMBY(Not In My Back Yard) is an acronym for the opposition by local residents to construction of intrusive facilities, which are often intended primarily to serve people living far away: such as new roads or rail lines, power plants, waste storage facilities or the like, or intended to serve "undesirable" people locally, such as drug rehabilitation centers, Halfway houses and the like. Other concerns expressed include increased traffic due to apartment buildings, occluded views, or loss of open space or parks. Such opposition typically comes from homeowners who fear that such developments will cause the resale value of their real estate to fall.
Generally people who express NIMBY sentiments acknowledge the need for the facilities, while arguing that they "just don't want them nearby". For example, most Americans agree that long distance electric power transmission lines are necessary, yet hardly anyone wants to live within sight of them - whether due to concerns for their safety or just because they look "ugly".
Some skyscraper aficionados use the term NIMBY for anyone who hates any kind of tall building or wants them torn down or restricted.
Extreme NIMBYism would be where someone moves into an area, and then complains about things like a small airfield that has been there for decades before they moved in, and all their neighbours have happily lived with. Unfortunately, at least in American law, the alleged source of the nuisance cannot raise "you came to the nuisance" as a defense.
NAMBY is also used to describe the Not in Anyones Back Yard philosophy.
NIMBY (an initialism for Not In My Back Yard) is an acronym for the phenomenon in which residents oppose a development as inappropriate for their local area, but by implication do not oppose such development in another's.
NIMBY and its derivative terms NIMBYism, NIMBYs, and NIMBYists, refer implicitly to debates, of development generally or a specific case, and as such their use is inherently contentious.
Also, it is a relatively recent term, the first printed usage of which the Oxford English Dictionary identifies as being in 1980 in the Christian Science Monitor, and the nuances of which are still disputed.
The blame for the detrimental effects that NIMBY suits have on both the environmental justice movement and the spirit of environmental laws cannot be placed solely on the members of the community.
Although NIMBY suits often involve concerns over environmental hazards, they are more often then not politically palatable fronts for concerns such as decline in property value or a desire to shift the project away from neighborhoods with political influence.
NIMBY suits often result in the loss of facilities that would have had a positive benefit for the community and the environment because of the expense of going through a judicial proceeding.
