Ecopath with Ecosim (EwE) is a free and
Components
EwE has three main components:
- Ecopath – a static, mass-balanced snapshot of the system[2]
- Ecosim – a time dynamic simulation module for policy exploration[3]
- Ecospace – a spatial and temporal dynamic module designed for exploring the combined impacts of fishing, the placement of protected areas,[4] and changing environmental conditions.
Capabilities
The Ecopath software package can be used to:
- address
- evaluate ecosystem effects of fishing[7]
- explore management policy options[8]
- analyze impact and placement of marine protected areas[9]
- predict movement and accumulation of contaminants and tracers (Ecotracer)[10][11]
- model effect of environmental changes,[12][13]
- facilitate end-to-end ecosystem model construction[14]
Development Ecopath version 6.0[15] received support from the Lenfest Ocean Program and the Pew Charitable trusts. In 2011 the Ecopath Research and Development Consortium was founded to share the responsibility of maintaining and further developing the approach with institutions around the world. EwE exclusively relies on user involvement for continued software development and releases of new versions.
The desktop version of Ecopath with Ecosim runs only on
Funding
In 2013, development efforts were centralized under Ecopath International Initiative, Spain, which coincided with a switch to a community-driven development model overseen by the Ecopath Research and Development Consortium.[17] As the approach does not receive any core funding, the Ecopath with Ecosim approach now relies entirely on user-contributed project funding for continued development and releases.
