    Sustainability Consequences of Making Land Change Decisions Based on Current Climatology in the Brazilian Cerrados by Daniel S. Silva, Eugenio Y. Arima

    Published 2023-04-01
    “…However, as areas with better soil and climate for agriculture become scarce, farmers have been advancing to the ecotone between the savanna and xeric shrubland, where precipitation is less reliable for rainfed agriculture. The expected increase in temperature will lead to extended drought periods, with negative consequences for surface and groundwater resources. …”

    Evaluating Crop Area Mapping from MODIS Time-Series as an Assessment Tool for Zimbabwe's "Fast Track Land Reform Programme". by Konrad Hentze, Frank Thonfeld, Gunter Menz

    Published 2016-01-01
    “…Although general LULC patterns were depicted in classification results and an overall accuracy of over 80% was achieved, user accuracies for rainfed agriculture were limited to below 65%. We conclude that phenological analysis has to be treated with caution when rainfed agriculture and grassland in semi-humid tropical regions have to be separated based on MODIS spectral data and phenological parameters. …”
