pop growth and land tweak
This mod does two things:
1) Increase pop growth rate to make late game population growth more historical. For example, late game annaul pop growth rate for a developed country (>15 sol) will be around ~1.5% instead of <1% in vanilla.
2) Added 2 new decisions: national cultivation program & land reclamation program which unlock after researching relevant techs. These decisions will increase arable land.
Reasons:
Population growth rate for great powers at 20th century hovers around 1.6%. In villina late game pop growth rate rarely exceeds 1%. Moreover, increased pop growth rate solves the problem where modernised countries run out of manpower in the late game.
Logically speaking, available arable land increases over time due to cultivation and reclamation. Gameplay wise, extra arable land allows for more subsistence farms which tampers the problem of over-population caused by increased growth rate in early to mid game.
Results:
A more historically accurate population in the late game. In vanilla, ai Russia has ~130M pop in 1920. With my mod, ai Russia ends with ~160M pop in 1920. According to google, Russia has 164M population in that time period.
