Kampala, Uganda (CNN) When Ugandan climate change activist Vanessa Nakate attended the World Economic Conference in Davos, Switzerland, she was excited to share her message with the world.

Instead, she ended up at the center of a fierce debate over race and representation in the media.

Nakate, 23, had been invited to attend a youth climate science event. When news coverage of the event emerged, she noticed she had been cropped out of a photograph , where she appeared alongside activists Greta Thunberg, Isabelle Axelsson, Luisa Neubauer and Loukina Tille.

Nakate told CNN that the incident points to a wider issue of erasure of African voices in climate action conversations.

"Africans have truly been erased from the map of climate action," Nakate said during an interview at her home in Uganda.

"Very many African activists have been doing a lot of work, putting in a lot of effort, trying to get their message heard and listened to," she added.

'Sad and worthless'

The cropped photo was taken by a photographer for The Associated Press, and Nakate confronted the agency about the incident on Twitter, writing "Why did you remove me from the photo? I was part of the group!"

She added in a video statement: "It was the first time in my life that I understood the definition of the word 'racism.' "

The AP apologized in a statement Friday saying it regretted publishing the photo.

The incident prompted soul searching within the organization, according to an AP news story. The story reported that the AP intended to expand diversity training for employees.

Nakate says the experience left her feeling "sad and worthless," because not only was she initially cropped out of the AP image, her presence was also not reported in initial versions of an article on the conference.

"My reaction was more of a feeling of sadness and a feeling of being worthless and having wasted my time at the press conference. Because I did not just see the photo, I went ahead to read the article. And, in the article still, I was not introduced as one of the activists who were at the press conference," she says.

Her name appeared in later versions.

A movement ignored

Nakate was inundated with support on social media after the AP photo went viral. Thunberg condemned the agency's action on her social media pages.

I'm so sorry they did this to you... you are the last one who would deserve that! We are all so grateful for what you are doing and we all send love and support!!❤️❤️💖💖💖hope to see you soon again!! — Greta Thunberg (@GretaThunberg) January 24, 2020

"The online reaction has been so powerful and very supportive. Despite all the hurt and the depression, I had very many people who came out and supported me," she said.

"People have been pouring out all kinds of support, and speaking against any kind of discrimination or injustice towards African climate activists."

Rather than erase her from the conversation, the crop instead has strengthened her voice and catapulted her to global recognition, with a newly verified Twitter account and thousands of new followers to her cause.

Can we all agree, that this's actually been a blessing in disguise for her? shit! for VANESSA NAKATE(apparently you MUST mention the name😂). I mean now more people around the world know & follow her.

Nakate says what happened to her is not an isolated incident and is she will fight to ensure that African activists have a seat at the global table.

"Many of these [African] activists have been going through these things, but they just did not have the strength to air them out," she said.

"Now is the time to put an end to it."

Reactions echoed Nakate's sentiment that the crop was symptomatic of a movement that largely has been ignored by Western mainstream media.

Climate justice activist Jamie Margolin said , "The press has been consistently 'cropping out' youth of color in their coverage of the climate action movement for years. We must rise up and demand better."

Africa most vulnerable to climate shocks

Nakate grew up in Kampala and got involved in activism in December 2018 after being bothered by unusually high temperatures in her country.

Drawing inspiration from Thunberg, she staged a solitary strike outside Uganda's Parliament to protest climate inaction and rising temperatures that was met with interest by security forces, she said.

'When I went to the Parliament, a couple of policemen checked my placard quite a number of times trying to look for a message or any kind of plot that I had against the government," she said.

Nakate is the founder of the climate action groups, Youth for Future Africa and the Rise Up Movement . She has taken part in 56 Fridays for Future protests and has spent more than 80 days campaigning for the Congo forests.

Experts say Africa is the most vulnerable to climate shocks, with more frequent droughts and floods stretching people to their limits as farmers and herders are left with little time to recover.

East Africa, which comprises Nakate's home country of Uganda, is facing its worst locust invasion in decades after one of the wettest seasons in 40 years came on the back of drought — a situation scientists say is becoming the new normal.

In Uganda, floods and landslides have become more frequent in recent years, and government sources estimate that 300,000 people have been affected and 65,000 displaced.

Over the weekend, Nakate returned from Davos to the home she shares with her parents and four siblings in Kitintale, a middle-class suburb of the country's capital, Kampala.

She said she believes the cropping incident has kickstarted a conversation that will change the framing of African climate change activists.

"Everyone is speaking against the erasure of African activists and the world has set their eyes on these African activists. I believe that now is the time for them to be given the platforms to speak out and to be listened to."
