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.

170 years ago today, the United Kingdom invited ‘All Nations’ to the Great Exhibition of 1851. Taking place in Hyde Park between 1 May 1851 and 11 October 1851, Expo 1851 London was an occasion for the United Kingdom and international participants to showcase human progress, notably in the area of industry and technology.

Here are some interesting facts about this unique global event:

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.
