The system calculates industry-leading metrics through a "spatial-first" engine. This means at a minimum, each farm needs to be represented on a map (e.g. a red-line boundary) to calculate key indicators such as county, waterbodies, proximity to flooding and more. 
When a habitat map (either current "baselines" or future "land management plans") are also shared, the metrics allow for a detailed assessment of those habitats' impact on risk and resilience. These can be detailed connectivity scores, or broader "habitat cover %" of the farm or portfolio - helping track key targets such as 30 by 30. 

The NRRR system is the product of years of sector-wide partnerships. This includes building on the Defra Biodiversity Metric (which underpins Biodiversity Net Gain), closely working with the UKHab Ltd team on iterations of the UKHabitat Classification, and numerous research bodies, such as UK Centre for Ecology and Hydrology (UKCEH), Oxford University and Rothamsted Research. 
Land App is also grateful to its wide-user base whom contributes iterative feedback for it's development. 

Land App has built the Nature, Risk and Resilience System to protect farmers' data. Therefore, we follow the Farm Data Principles.

Whichever user created the map owns the data (as it was created by and for the end-user).

The NRRR system provides a route for the "analysis" of that data (e.g. the metrics) to be shared with one or more recipients. At any-point, that "end-user" can revoke access, thus being "forgotten"  by the system.
