# FEMA Ecosystem Service Value Updates

Source: FEMA [June 2022](https://www.fema.gov/sites/default/files/documents/fema\\_ecosystem-service-value-updates\\_2022.pdf)

Primarily utilizes the seminal Millennium Ecosystem Assessment (2001) categories.

FEMA has updated its approach to hazard mitigation by incorporating Ecosystem Service Values (ESV) into its Benefit-Cost Analysis (BCA) Toolkit, measured in terms of dollars per acre per year ($/ac/yr). These updates extend across nine different land cover and ecosystem types and 14 categories of ecosystem services. The inclusion of ESV not only makes the toolkit more comprehensive but also simplifies the application process for subapplicants seeking to implement Nature-Based Solutions (NBS). Recent policy changes have expanded eligible NBS activities and eliminated previous benefit-cost ratio requirements, making it easier for projects focused on ecological benefits to receive funding. This marks a shift towards more sustainable and equitable hazard mitigation strategies.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.basin.global/appendix/ecosystem-services-classification/ecosystem-services-frameworks/fema-ecosystem-service-value-updates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
