WP0 - Landscape selection

In each region, between 30 and 90 landscape of 1 km by 1 km have been selected to represent independent gradients in crop diversity and crop configuration (crop mean size or total border length). This selection was based on existing land cover maps or high-resolution land cover data derived from satellite and airborne imagery using the same protocol.

The objectives of this protocol were:

  1. to select agricultural landscapes (more than 60% of production area)
  2. to maximize the selected range of heterogeneity for both variables (crop diversity and crop configuration)
  3. to minimize confounding factors (e.g. proportion and type of natural habitats, crop ID, spatial trends)
  4. to select suitable sampling points within each landscape
