African migrant workers harvest in Spain vegetables and fruits for supermarkets in northern Europe. They earn below the minimum wage and live in deplorable conditions, in selfmade houses with no acces to clean drinking water and electricity. Their hovels are most of the times hidden on wasteland behind the farms they work for. Covid-19 has drastically worsened conditions for migrant workers around the world, this is also the case in Spain. More migrants had arrived from Africa, because of the bad economic situation in their country due to COVID-19, also there was less work in Spain and migrant workers couldn’t return to Africa or move freely within Spain. As a result the 'chabolas' - the shantytowns of selfmade houses - are overcrowded. The UN has ordered to stop this tragedy and calls it a violation of hyman rights. It is the tragedy of the European food supply.
