Reminds me of the infographic "over half the world lives in this circle", the circle containing countries in the region of China, India and ASEAN. All on or near equator. All countries in a position to develop rapidly short-term. India/Bangladesh/Pakistan/continental ASEAN corridors are prime waterwars candidates. The only saving grace of island ASEAN is they're geographically constrained from massive conflict and migration. There's a lot of zero-sum resource competition in the area which doesn't bode well.
