Land Utilisation and Capability Indicator (LUCI) is a tool that allows users to explore the capability of a landscape to provide a variety of ecosystem services, such as agricultural production, flood and diffuse pollutant mitigation, carbon sequestration, and habitat provision. It allows for the development of alternate scenarios so that different management decisions can be assessed and compared.
The Land Utilisation and Capability Indicator (LUCI) model allows the mapping of ecosystem services from the sub-field to national scale, and modelling of the impact of management services on these services. It also allow assessment of likely trade-offs and opportunities for spatially optimising interventions. Currently services include agricultural productivity, flood risk, erosion, nitrogen, phosphorus loss to rivers, carbon storage and emission rates, habitat diversity, and connectivity for broadleaved woodland species.
LUCI, which started off as Polyscape (see Bagstad et al. 2013; Jackson et al. 2013), is an integrated, spatially explicit, multi-ecosystem services framework that identifies the impact and trade-offs of land management actions from a very fine (subfield) scale to a regional or national level.
LUCI is a GIS toolbox that uses multiple criteria analysis to explore the impacts of decisions on land use or management changes. It is primarily an effective visualisation tool for determining trade-offs in different ecosystem service provision at the landscape scale, with a strong focus on agricultural landscapes.
There are six tools; five consider current and potential impacts of land management change on single service criteria. These are 1) habitat networks; 2) flooding; 3) erosion/sediment delivery; 4) carbon sequestration; 5) agricultural productivity. The sixth tool displays synergies and trade-offs amongst any number of these five ecosystem services. The tool is implemented in ArcGIS.
All LUCI calculations and valuations are produced at the resolution of the input digital elevation model (DEM). This is the obvious choice for water and diffuse pollution services and allows for sub-field management changes e.g. riparian strips and field boundaries as well as sub-catchment and catchment changes to be assessed.
It is designed to be simple and transparent, with the ability for engagement by (and customisation for) stakeholders. LUCI uses innovative algorithms that maintain biophysical principles and spatial connections, but which are orders of magnitude faster than previous approaches.
Changes in land management at field level can be inputted to the tool and “traffic light” coded impact maps, produced in seconds to minutes, allowing quick visualisation of the impact of different decisions on ecosystem services manifest at landscape scales. Interactive capabilities to facilitate stakeholder engagement and to allow local requirements and knowledge to be easily incorporated in decision making are included.
LUCI is particularly useful if you are interested in the cumulative impact of many small features (or changes to these features) in the landscape on a variety of ecosystem services. For example,if you are a land manager you can explore how riparian planting might change river water flow and quality, or where you might be able to plant trees to improve drainage on your land and provide shelter for stock. If you are managing a catchment, you could investigate where and how you could retain water in the upper catchment to improve flood protection downstream.
Such a tool may also be used in the future to further conservation in areas outside public conservation land (e.g. agricultural landscapes), including where conservation is contentious due to conflicting social, economic and environmental values, by:

Spatially explicit GIS model. Links combined spatial input data for each pixel with a lookup table and applies process representation for flow of water and nutrients over the landscape. Habitat connectivity is simulated based on cost-distance approach taking into account characteristics of adjacent habitats. The model is temporally lumped- calibrated to give long term annual average values.

Each application uses increasingly detailed input data and the results are compared to OVERSEERTM predictions, as well as instream nitrogen (N) and phosphorus (P) measurements.
