This paper explores the application of multiobjective Genetic Algorithms (mGAs) to rural land use planning, a spatial allocation problem. Two mGAs are proposed. Both share an underlying structure of: fitness assignment using Pareto-dominance ranking, niche induction and an individual replacement strategy. They are differentiated by their representations: a(More)
Silvopastoral agroforestry can satisfy some objectives required of European land-use systems: reduced agricultural production, increased timber production, increased product diversity and environmental enhancement. A national network experiment was set up on four sites, each representative of a UK grassland farming area, with three replicates of common(More)
Silvopastoral systems, where stock graze between widely spaced trees, are a viable land use option in the British Isles. An experiment (the National Network Silvopastoral Experiment—NNE) was set up at 6 sites in the late 1980s to quantify outputs from and to study the ecological interactions occurring between components of the system. Studies were carried(More)
