The Expo 2015 (Universal Exposition) opened in Milan on 1 May and will run until 31 October. By following the theme Feeding the Planet, Energy for Life, 145 countries will show their commitment to creating sustainable ways of producing and delivering food across the globe in a bid to safeguard the planet.

Although the exposition was welcomed by many, it has also been the object of severe criticism by people from the so-called "No Expo" movement. One day before the opening, hundreds of students marched through the streets of Milan, as they believe the event will not benefit Italy but only corporations collaborating with it. On the day of the opening, masked protesters clashed with police and set cars and shops alight in central Milan.

As the six-month-long event continues amid financial scandals and protests, IBTimes UK looks at some of the best pavilions at the exposition that an estimated 20 million people are expected to visit.

Nepal

The Nepal pavilion aims to shed light on the country's need to develop programmes that can guarantee all its citizens have enough to eat. The decision was made as the country's food production is not at the same level of the population growth.

The pavilion also shows Nepal's biodiversity, with a focus on mountain farming. The building was completed by Italian and Nepalese volunteers after the country's representative went back following a devastating earthquake that killed more than 7,500 people.
