This tar.gz contains four folders, for two parameterizations of two crops: wheat and peas. Par 1 and Par 2 for each crop represent high and low assumptions about agricultural intensity, respectively. See Contreras et al. 2018 for details or parameterizing LPJmL for past agriculture. The paleoclimate reconstruction used to generate these iterations of LPJmL is a downscaled version of the Guiot and Kaniewski 2015 dataset.

This dataset includes LPJmL (the Lund-Potsdam-Jena managed land model; see Bondeau et al. 2007 for details) results for high and low assumptions (Par 1 and and Par 2, respectively) about agricultural intensity for two crop types (wheat and peas) over the period 8400 – 1400 BP. Parameterization of LPJmL for past agriculture is based on archaeological, historic, ethnographic, and experimental data about pre-industrial agriculture, detailed in Contreras et al. 2018. These 300m-pixel annual reconstructions of potential agricultural productivity are based on paleoclimate data downscaled (see Contreras et al. 2018b) from Guiot and Kaniewski’s Mediterranean-wide Holocene reconstruction (Guiot and Kaniewski 2015).
