The East African nation brought just a one-member team here to the 2017 edition.

David Emong made Ugandan history last night after claiming the country’s first-ever medal at the biennial event with gold in the men’s 1500 metres T46 event. 

The UPC had hoped, however, to see three other athletes to join the Rio 2016 silver medallist  - Christine Akullo, Sam Mubajje and Al-Bashir Bwaga.

But Bumali said the cost of the event meant they could only afford to bring Emong.

"This event was so, so expensive and really for developing countries like Uganda it becomes very difficult," he told insidethegames following Emong's medal ceremony today. 

"We started preparing for this event with 10 people, then out of the 10 we realised we cannot raise that money - €880 (£770/$1,010) for the participation fee, then £780 ($1,020/€890) for accommodation, then almost $1,500 (£1,150/€1,310) for the air ticket - so in total it was too much for an athlete to come here.

"So what we did, we decided to reduce the number to four, three men and one woman, but then again we failed to raise the money for the four people in time.

"When we communicated to the IPC that we could get money for four people, then they said, 'No we have already come out with the schedule, we cannot change the schedule because of Uganda', so we were not able to take those three athletes."

Bumali is now appealing to the IPC to look into the cost of the event.

"If we’re looking at developing sports, if we're looking at inclusive participation then they should have an alternative for such countries," he said.

"Africa has 54 countries, but we have less than 15 here.

"Not because they have no athletes, but because the event is very, very expensive.

"So as they look for sponsorship for this event, they should also look at ways of helping these countries that are coming out to participate so that we give opportunities to these other athletes. 

"Otherwise, as African athletes, we lose."

Bumali claims he sent around 100 e-mails prior to the Championships, appealing to the IPC to either waive or reduce the costs.

"They were saying there's no compromise on participation, there’s no compromise on accommodation fee," he said.

"I started communicating, I think, from March, but it did not bear fruit.

"When I came here, I again spoke to two members of the IPC and I told them, 'Look here, if you really want Africa to benefit in this, you must devise means of developing African countries because representation is very important'.

"If it’s a World Championships it must be inclusive, but it cannot be because of some resources that are required."

Emong beat defending champion Samir Nouioua of Algeria to claim the men’s 1500m world T46 title.

Nouioua was the man who beat him to the gold medal at Rio 2016.

Bumali described it as a "real joy" to see Emong, Uganda’s first and only Paralympic medallist, triumph.

"It sends a message - it sends a message to the country, it sends a message to sportsmen in Uganda, it sends a message to corporate companies," he said.

"So I’m really happy and I’m happy on behalf of David because he said when we were in Rio and he got a silver medal that 'The Algerian guy has robbed my gold medal, but I’m going to fight for it in the World Championships'.

"Indeed he has made it.

"I almost cried when he also almost was unable to come, but I’m happy he finally made it here and he achieved his dream."

Emong now has eyes set on claiming the Paralympic gold medal at Tokyo 2020.

"When we were talking this morning he told me, 'President I need to continue training because I want to get the same gold medal in Japan' and we will definitely give him the support to achieve his dream," Bumali said.

Southern Africa nation Namibia were only able to take part in the Championships here after a late financial deal was arranged so they could travel to the event.

There had been uncertainty about their participation after the Namibia Sports Commission claimed they did not have the funds to finance the trip. 

Disability Sport Namibia, however, provided the necessary funding of NAD$470,000 (£28,000/$36,000/€31,000) to ensure the team's participation. 

When contacted by insidethegames about Bumali's comments, the IPC said: "We fully appreciate the financial challenges many countries face. 

"This is why we are currently reviewing the delivery model of the Championships with an aim to increase the financial investment in all areas. 

"By increasing the investment in events, we will ultimately be able to reduce the costs to our membership.

"Through the Agitos Foundation, the IPC’s development arm, we are also working to improve the organisational capacity of developing countries. 

"By doing this we aim to better their own fundraising efforts through marketing activities and stakeholder relations.

"Currently Para-sport is not in a position to deliver world class events solely through commercial and broadcast revenue. 

"Around 80 per cent of the monies generated via competition fees go directly into covering an Organising Committee’s costs, with the remainder providing support to the International Federation to cover its administration and development activities.

"It must be highlighted as well that the fee for World Para Athletics competition has not changed over the last eight years. 

"During this same period of time the level of services provided to athletes and the delivery of the Championships have increased dramatically, as highlighted here at London 2017."
