Expert opinion and model of natural pest control in agricultural landscapes

<table> <tbody> <tr> <td> <div>The survey asks expert How they would estimate the capacity different land use (herbaceous semi-natural habitat, forest edge, forest core) to support the abundance of the following insect groups in the landscape: &lsquo;complete generalists&rsquo; &lsquo;specialized predators&rsquo;, &lsquo;parasitoids&rsquo;. The score is provided on a scale from 0 (no relevant capacity) to 10 (very high relevance). For each opinion, experts provided a level of confidence: 1 'I don&rsquo;t feel confident with my score', 2 'I feel fairly confident with my score&rdquo; and 3: 'I feel confident with my score'. In the same way experts were asked to rate a baseline scenario of agricultural fields defined as as a conventionally managed average field (with an average field size of 3-7 ha, fertilization and pesticide application compared to the region of interest) of medium crop diversity with three functional groups over 4 years (e.g., cereal, oilseed crop, root crop). Then experts were asked how much a single change from one practices to an alternative one (e.g., conventional to organic) would affect the score they provided - 50 to - 100% = considerably worse -20 to -50%= notably better -1 to -20% = slightly worse 0 = no change +1 to 20% = slightly better +20 to 50%= notably better + 50 to 100%= considerably better +100 to 200% = extremely better/</div> <div>&nbsp;</div> <div>Finally experts were asked about the distance at which landscape change affect the abundance of the three group of natural enemies.</div> <div>&nbsp;</div> <div>The survey was conducted from April to June 2021.</div> <div>&nbsp;</div> <div>The scores for each practices are derived by mixed effect model and provided in the file Code_Habitats.csv. This file is used in the R model provided here to calculate natural pest control using the weighted moving window describe in Riggi et al., 2024 Ecological Indicators. NPC_Model_Riggi.R is the code of the model Fields_AOI.shp represent an example of fields with agricultural land use information CadasterEnv_AOI.tif is the land use map CADASTERENV_Label_to_change_input.csv allows the reclassification of land use into forest edge, core and herbaceous areas Code_Habitats-1.csv contrains the values associated to each support of land use for natural pest control.
