The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee
Agribusiness, EarlyView.ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Dust-wind interactions can intensify aerosol pollution over eastern China
Nature Communications, 2017 Anthropogenic aerosol and calm conditions give rise to winter haze episodes in eastern China. Yanget al. show that these weak winds also decrease natural dust emissions, reducing the land–ocean temperature difference and associated winds, enhancing air ...
