On the anniversary of the establishment of the United Nations Food and Agriculture Organization (UN-FAO), October 16th, World Food Day (WFD) calls for global action against hunger. Eradicating hunger is one of the Sustainable Development Goals and a major societal challenge, in particular in view of climate change and rising populations. This edition of WFD is themed ‘Climate is changing. Food and agriculture must too.’ and calls upon countries to address agriculture in their climatic plans. A message that will hopefully be taken up in the important discussions of the UN Climate Change Conference, COP-22, that takes place in Morocco in November. To this occasion, PROBA-V takes a false-colour look at modern agricultural fields with centre-pivot irrigation (in red) and consumption of underground water resources in the Wadi As Sirhan basin of Saudi Arabia, amidst the yellowish desert sands and surrounding low hills and rocks.
