Charity fundraiser David Walker helped sew the seeds for a sustainable future for malnourished youngsters in Tanzania during an emotionally charged trip of a lifetime to Africa.

David from Webheath, Redditch in Worcestershire, was part of a delegation from leading business-to-business express delivery company, TNT, who flew out to Kilimanjaro to support the United Nations' World Food Programme (WFP) feed and educate impoverished orphans and youngsters.

Along with colleagues from all over the UK, David, the company's Head of Communications, flew more than 5,000 miles to witness, first hand, how the WFP makes the best possible use of TNT's annual donation of more than £7.5million to help feed and sustain hungry children.

One of the highlights of the five-day trip was a visit to the Kinyamwenda Primary School in the Singida District of Tanzania, where hundreds of children are fed and educated, courtesy of funds generated by TNT and the work conducted on the ground by WFP volunteers.

During his time at the school, David helped prepare agricultural land for new crops to provide for future harvests and ensure sustainable food supplies for years to come. In addition he delivered a speech - in the local Swahili dialect - to a crowd of more than 2,000 children, tribal leaders and villagers as part of the friendship mission.

Remarking on the whole experience, David said: "It was very humbling, especially after spending time with young orphans and children who survive on just one bowl of rice and maize a day.

"I felt privileged to have spent time with some remarkable children. They have so little in life and yet they never seemed to stop smiling. They melted our hearts and it put into perspective how fortunate we are with what we have and how we are able to live here in the UK."

TNT Express Services is the country's biggest and most successful business oriented courier company and, as such, is very aware of its corporate social responsibility obligations. Apart from huge backing for the WFP, it has also raised millions for the UK-based children's charity, Wooden Spoon.
