Agricultural diversification, productivity, and food security across time and space

Abstract This article presents an investigation of agricultural production risk over time and across space its implications for food security. The econometric approach involves a Quantile Autoregressive (QAR) model copula to provide flexible representation the distribution yield evolution space. analysis relies on two‐step estimation method evaluate multivariate spatial temporal evolution. Linkages between economics security are explored, with welfare cost insecurity. is illustrated in application regional wheat corn yields Italy. provides new useful information evolving linkages risk, productivity, Our integrated documents role diversification productivity growth along their effects
