A unique ‘tree twinning’ project between British and Nepali schools has shown how trans-continental partnerships like these can increase green cover even in crowded urban centres, help clean the air and get school children involved in environmental protection.

Under the project initiated by the Dwight London School in collaboration with school members of the Nepal Trust for Nature Conservation’s (NTNC) Friends of the Zoo program, when a tree is planted in the UK, another tree is planted in Nepal. London’s Barnet Council is providing 2,000 saplings and space to plant them.
 
On 8 September, Deputy Mayor of Barnet Council Lacchaya Gurung inaugurated the partnership by planting a Himalayan Birch tree at Dwight School London. Gurung, who was in the Brigade of Gurkhas in 1980 and retired after 18 years of service with the rank of staff sergeant, was optimistic about  the long-term impact of the project.
