Yang, P.Cai, X.Khanna, M. Dec. 2, 2020. Data from: “Farmers’ Perceptions of Marginal Land for Biofuel Crops.” University of Illinois Urbana-Champaign. DOI: 10.13012/B2IDB-3074705_V1.


Maps show (a) marginal land likelihood; and (b) the factor that dominated in the determination of (a). (Total_area: farm size, Prcp_grow: growing season precipitation, Rootaws: root zone soil water capacity, Mean_slope: average slope, Tmean_grow: growing season mean temperature, Trange_grow: growing season diurnal range of temperature)

The dataset includes the survey results about farmers’ perceptions of marginal land availability and the likelihood of a land pixel being marginal based on a machine learning model trained from the survey.

Two spreadsheet files are the farmer and farm characteristics (marginal_land_survey_data_shared.xlsx), and the existing land use of marginal lands (land_use_info_sharing.xlsx).

Note: the blank cells in these two spreadsheets mean missing values in the survey response.

The GeoTiff file includes two bands, one the marginal land likelihood in the Midwestern states (0-1), the other the dominant reason of land marginality (0-5; 0 for farm size, 1 for growing season precipitation, 2 for root zone soil water capacity, 3 for average slope, 4 for growing season mean temperature, and 5 for growing season diurnal range of temperature). To read the data, please use a GIS software such as ArcGIS or QGIS.
