2.7 Measuring changes in the system
2.7.1 - Describe and evaluate methods for measuring changes in abiotic and biotic components of an ecosystem along an environmental gradient.
2.7.2 - Describe and evaluate methods for measuring changes in abiotic and biotic components of an ecosystem due to a specific human activity.
2.7.3 - Describe and evaluate the use of environmental impact assessments (EIAs).
Environmental impact assessment
EIA is a report prepared before the project is started and it estimates human impact and possible environmental consequences of certain action. An EIA involves production of a baseline study before any environmental development, assessment of possible impacts, and monitoring of change during and after the development.
Firstly, it was introduced in 1969 in the US, where government passed National Environmental Policy and since then all governments around the world seem to like this assessment. Governments use EIA to protect nature and ensure its sustainable living. Nearly all countries have limits on Environmental impact and it is a requirement in every developed country. EIA shows relative disadvantages and advantages of development. These measurements are represented as basic study measurements. EIA mainly displays changes in:

- Microclimate (climate)
- Biodiversity
- Specific identification of impact. (Scoping)
- Predicting the scale of potential impact.
- Limiting the impact and doing project sustainably. (Mitigation)
