The dynamic nexus between climate changes, agricultural sustainability and food-water poverty in a panel of selected MENA countries

This study attempts to examine the dynamic relationships between climate changes, agricultural sustainability and food-water poverty in a panel of MENA countries over the period 1990–2016. A panel co-integration, pooled least squares regression, pooled fixed effects, and pooled random effects models...
