Environmental mitigationFrom Wikipedia, the free encyclopedia

Environmental mitigation, compensatory mitigation, or mitigation banking, are terms used primarily by the

United States government and the related environmental industry to describe projects or programs intended to

offset known impacts to an existing historic or natural resource such as a stream, wetland, endangered species,

archeological site or historic structure. To "mitigate" means to make less harsh or hostile. Environmental mitigation

typically a part of an environmental crediting system established by governing bodies which involves allocatingdebits and credits. Debits occur in situations where a natural resource has been destroyed or severely impaired an

credits are given in situations where a natural resource has been deemed to be improved or preserved. Therefore,

when an entity such as a business or individual has a "debit" they are required to purchase a "credit". In some case

credits arebought from "mitigation banks" which are large mitigation projects established to provide credit to

multiple parties in advance of development when such compensation cannot be achieved at the development site o

is not seen as beneficial to the environment. Crediting systems can allow credit to be generated in different ways.

For example in the United States, projects are valued based on what the intentions of the project are which may b

to restore, create, enhance, or preserve a natural resource.

Advantages

Environmental mitigation and crediting systems are often praised for the following reasons:

Development friendly

Mitigation is a more development-friendly alternative to strict environmental laws because it allows development to

occur where environmental laws might prohibit it.

Mitigation industry

Mitigation inevitably creates a "mitigation industry". By requiring those who impact natural resources to purchase

credits, a demand for mitigation credit is formed. Businesses related to environmental work typically benefit from

such a system.

Targeting ecological value

Assuming regulation assures that credit adequately reflects ecological value, mitigation has the potential to save and

restore the most valuable environmental resources at the least cost. This is because buyers are typically looking for

mitigation credits that are both cheap and the most likely to meet regulatory requirements for creation of credit.

Cost burden

Mitigation systems place the environmental costs of development mostly on the individuals or entities that are

impacting the environment. Without environmental mitigation, costs of alleviating environmental damage caused by

development could be placed in the hands of the government which would in turn pass costs on to taxpayers not

responsible for environmental impacts.

Benefit to landowners

Land previously unused or impractical for development is given greater monetary value under a mitigation system.

For instance, land in floodplains may be impractical for commercial or residential development but conductive for

mitigation activities. Land in rural areas with very little potential for growth are more valuable when given the

opportunity to be used for mitigation credits.

The following are criticisms of environmental mitigation and crediting systems:

Incorrect allocation and valuation of credits and debits

Mitigation regulations may not properly take into account the total ecological losses and gains associated with

environmental impacts or mitigation when allocating debts and credits. Governing bodies are primarily responsible

for prescribing the ecological criteria required to attain credits for mitigation. They are also responsible for valuatio

of credit. Problems with the allocation and valuation of credits and debts might be due to the complexity of

assessing the ecological value of natural resources, their capacity to change over time, and/or a lack ofunderstanding about what is beneficial or harmful to the environment.[citation needed]

Effects on land cost and availability

Some mitigation work requires buying large amounts of land or putting it in conservation easements. Because of

this, mitigation could be seen as contributing to increasing the cost of land. Mitigation can be in direct competition

with other rural land uses such as agriculture and residential development.

Problems with pre-existing credit

3/3



Because mitigation credit can be applied to existing natural resources, landowners can be given credit to sell for

resources that already exist and would have been preserved or naturally restored regardless of mitigation laws.

Undermining preservation efforts

Despite its goals of minimizing ecological loss, mitigation can be seen as a "loophole" that allows environmental

destruction to continue.[1] The lower the cost of credits are, the more cost effective it becomes for buyers to simpl

mitigate for environmental impacts rather than preserving them. Because ecological success of mitigation work is nguaranteed, there is a greater risk of net environmental loss through failed, ineffective mitigation work intended to

compensate for existing functioning natural resources.[citation needed]

Mitigation can also undermine existing preservation efforts. If an environmental asset is set aside for mitigation

purposes, that asset can continue to be damaged until a project arises that requires mitigation. At that point, the

asset in question may be damaged beyond repair or the cost of mitigation may increase. Even if no further damage

has been done, a net loss to society has occurred if the cost of mitigation is higher than if volunteers completed the

work.
