Only about 0.007 per cent of the planet’s water is available for human consumption, with the vast majority of water – in frozen glaciers or seawater – of no use for drinking, cooking, bathing or cleaning. Furthermore, the scarcity of freshwater is exacerbated by polluted rivers, lakes and groundwater, and the depletion of these water sources in many populated areas.
Around the world, 785 million people lack access to safe water and children are amongst the most affected by the threats linked to a lack of safe water, sanitation and hygiene services. While these diseases are preventable, every 90 seconds, a child dies from a water-related disease.
Desertification, and specifically the loss of fertile arable land, is a phenomenon that poses a major threat to global food production, particularly in the developing world. About 12 million hectares of arable land is lost to erosion each year, and it is estimated that land degradation in the next 25 years has the potential to reduce global food production by up to 12% (UNCCD).
Vaccine wastage is a global problem: WHO estimates that up to half of all vaccines are lost every year, largely due to the vials not being stored at the right temperature during storage and transport.
For this reason, many children miss out on essential vaccinations. To help combat this issue, Expo 2020 Dubai’s Global Best Practice Programme selected the UNICEF Drones Programme, which works towards efficiently delivering vaccines via drones, as a way to spotlight and expand the initiative on a global scale.
At least 2.2 billion people are blind or visually impaired. That’s more than a third of the global population who may have difficulties with daily tasks that are dependent on the ability to see correctly: checking expiration dates, distinguishing colours, reading instructions, etc.
