Rethinking Food Systems

Over decades, as populations have grown, more people are consuming – and wasting more food – than ever before. Unsustainable food production and consumption patterns are a common thread, running through many of the greatest challenges facing humanity today.

Between 2000 and 2010, large-scale commercial agriculture accounted for 40 per cent of tropical deforestation; and local subsistence agriculture was not far behind, accounting for another 33 per cent. But human food systems depend on biodiversity to function, and conventional food systems reduce biodiversity – effectively destroying their own foundation.

Epidemiology and evolution of Middle East respiratory syndrome coronavirus, 2012–2020

The ongoing transmission of the Middle East respiratory syndrome coronavirus (MERS-CoV) in the Middle East and its expansion to other regions are raising concerns of a potential pandemic. An in-depth analysis about both population and molecular epidemiology of this pathogen is needed.

Methods

MERS cases reported globally as of June 2020 were collected mainly from World Health Organization official reports, supplemented by other reliable sources. Determinants for case fatality and spatial diffusion of MERS were assessed with Logistic regressions and Cox proportional hazard models, respectively. Phylogenetic and phylogeographic analyses were performed to examine the evolution and migration history of MERS-CoV.
