Strata is a partnership for practice, research and innovation.

Strata is a collaboration between the United Nations Environment Programme. (UNEP) and the Food and Agricultural Organization of the United Nations. (FAO) under the EU-UNEP Climate Change, Environment, and Security Partnership. The platform is powered by Earth Map., a user-friendly tool for complex land monitoring based on Google Earth Engine’s big data capabilities, allowing users to undertake complex analysis of earth observation, environmental and climate data in a simple manner.

The Strata methodology. and prototype were developed in 2021-2022 in partnership with the University of Edinburgh. and EarthBlox., with support from the EU and the Government of Norway. Find out more about the methodology here.

Since the beginning, Strata has been guided by three values:


For effective solutions, Strata uses meticulously sourced data and rigorously validated methodologies, delivering trusted insights for informed decision-making.


Strata ensures equitable access to crucial information by utilising open-source data and offering a user-friendly interface. Our commitment to accessibility empowers users to identify high-risk areas without barriers.


Tailoring to diverse user needs, Strata provides insights at various scales—from national to local levels —alongside customisable layer views and flexible export options, ensuring adaptability to unique contexts and requirements.

The challenge

Across the globe, the impacts of climate change, environmental degradation and the mismanagement of natural resources are undermining livelihoods and damaging essential infrastructure. In already fragile or crisis-affected contexts, these impacts can exacerbate existing socio-economic risks in ways that can lead to increased competition over scarce resources, displacement, and conflict. At the same time, violent conflict and political instability can undermine climate change adaptation efforts, leaving vulnerable communities poorer, less resilient, and ill-equipped to cope with the effects of climate change.

The UN Security Council, the African Union, the G7, and other organisations have called for improved analyses of interlinked climate change and security risks to inform policy and programmes in crisis-affected contexts. Up to now, however, the capacity for data-driven assessments of converging environmental and security risks has remained in the hands of a limited set of experts. There is an urgent need to democratise environmental and climate security analysis by making such capacity available to practitioners and policy makers without prior technical know-how.

The Solution

The United Nations Environment Programme (UNEP) and its partners have developed Strata to enhance monitoring, analysis, and early warning of environmental and climate-related security risks. This web-based, easy-to-use data platform supports practitioners and policymakers to identify and track environmental and climate stresses potentially driving threats to peace and security.

Strata allows analysts, policy makers and practitioners to access and use climate security data in their daily work, including to raise awareness of converging risks, to design and prioritise policy and programming responses, and to monitor and evaluate interventions.
