The rise in agricultural output is mainly due to increased mechanization, better pest control, improved crops, fertilizers and farm management. But you cannot keep improving those indefinitely; population growth and land reduction will inevitably break the trend.
Good job on taking in other people. We're not that spacious, and barely above sea level (as yet). I won't see my house flood over, but my son might
Still, I'm better of than half of my nation living below sea level, dikes protecting them.
Raising a dike say 2 meters makes them about 4 times as expensive.
