March 22 is World Water Day, designated to focus our attention on the importance of water. The theme for World Water Day 2018 is ‘Nature for Water’ – exploring nature-based solutions to the water challenges we face in the 21st century. But of course water is essential for life, and thus affects every aspect of human development, as well as the ecosystems that support us. Today, 2.1 billion people still live without safe drinking water at home; affecting their health, education and livelihoods. Earlier this week, on a visit to CABI Headquarters in Wallingford, CABI book author Dr Stroma Cole gave a talk on gender equality and tourism in which, with World Water Day this week, she focused particularly on water issues, and how women bear the brunt of the problems which can be created when tourism development increases demand for water. Dr Cole, a senior lecturer in tourism geography at the University of the West of England and a Director of Equality in Tourism, has worked on tourism and water inequality in Indonesia, Costa Rica and India, and in her presentation focused particularly on the situation in Labuan Bajo, a rapidly growing gateway town to Komodo National Park in Indonesia.
