v3.8 was released in November 2020, provided with a full re-estimate of the time-series (to 2021) that heavily relies on “now-casting” economic structure (and environmental extensions). The time-series extends into the future (2021), but this is based on the now-casting procedure and projections of GDP and aggregate trade of the IMF.

Identifying production hotspots for global crop and livestock consumption by a Spatially Explicit Multi-Reginal Input-Output model ( Zhongxiao’s work on Global Food Security). Keywords: primary crops; animal husbandry; spatially explicit; Multi-Regional Input-Output(MRIO) analysis. Research background Food security is challenged by increasing global food demand driven by population growth and animal-based diets. More crop production requires increasing areas of land and fresh water, causing associated environmental impacts1. Also livestock should be a focus as their feed contains harmful ingredients2 which will released to our environment finally.

The Leontief production function does not allow for substitution between inputs. Scenarios of lockdown Lockdown periods Strictness of the first lockdown period Strictness of future lockdown periods Labour loss dominates the economic loss in the model.
