The Gates Foundation’s work with vaccination will have a huge impact as longevity increases and child mortality drops, people tend to respond to the lower risk by having smaller families. Plus the general education and empowerment of women is a big strategy to control birthrates as well since it gives women more life options beyond motherhood. You will notice that the overall western narrative is that we have a low birthrate crisis and need to support family life better, but in Africa the effort is to bring that birthrate down. Touchy, touchy subject, especially since a massive population increase in the global south is already baked into the math and is as close to inevitable as it gets.
Zero-sum thinking can get you into a whole lot of trouble here, which is why I am basically a solar punk. If that’s not realistic we are screwed anyway and will tear each other to pieces over the last scraps of the biosphere.

Perhaps there are good solutions worth talking about, such as what kinds of crops and foods we incentivize and disincentivize, with concomitant impact on the environment and, ultimately, the space we need to thrive. Or another is giving women access to birth control so that they can make decisions about what they perceive to be an improvement to their own lives and that of their families.
