Tikta – Software for implementing the Water Framework Directive and Marine Strategy Framework Directive

What is Tikta?

Tikta enables users to assess the risks posed by multiple human pressures on marine ecosystem components through customisable spatial and non-spatial analyses. It integrates data and metadata management, spatial analysis and visualisation of results through maps and tables within a single platform.

The software currently includes two core assessment methods:

• CEA – Cumulative Effects Assessment.
• NEAT – Nested Environmental status Assessment Tool.

Additional analytical methods and functionalities will be incorporated in future releases.

What challenge does it address?

Tikta supports the integrated assessment of the cumulative impacts of human activities on marine ecosystems.

It is designed primarily for scientists and technical users experienced in handling environmental and spatial data, while its outputs are presented in a format that is readily interpretable by managers and decision-makers.

Although the software is not tied to a single regulatory framework, it directly supports assessments required under the Marine Strategy Framework Directive (MSFD), the EU Biodiversity Strategy and the Nature Restoration Regulation. It is also compatible with the Water Framework Directive (WFD), the Habitats Directive, and other environmental policy frameworks.

How does it work?

Tikta combines spatial and environmental data to assess ecological status and cumulative risks through two main modules:

• CEA (Cumulative Effects Assessment): performs spatial analyses of the cumulative risks associated with multiple human pressures on ecosystem components, producing GIS-based maps that identify the most affected areas.
• NEAT (Nested Environmental status Assessment Tool): assesses environmental status using ecological indicators and spatial data in accordance with the MSFD. It identifies the contribution of individual habitats and ecosystem components to overall environmental status and supports the definition of measures to improve or maintain Good Environmental Status.

Key benefits

• Regulatory compliance – supports assessments in line with the Marine Strategy Framework Directive.
• Flexible application – suitable for different spatial scales and a wide range of marine ecosystems.
• Integrated assessment – combines multiple environmental indicators within a single assessment while quantifying uncertainty.
• Scientifically robust – developed and validated through international research projects.
• Decision support – helps inform conservation strategies and the sustainable management of the marine environment.

Success stories

• Used in European research projects and by the European Environment Agency (EEA) to support environmental status assessments of marine and coastal ecosystems.
• Applied in environmental monitoring programmes aligned with European Union legislation.
