Unfortunatelly, current models show that the problem of sustainable human population is too hard for current Global social and economic system. See the work done for NASA/GSFC titled "Human and Nature Dynamics (HANDY): Modeling Inequality and Use of Resources in the Collapse or Sustainability of Societies" http://www.atmos.umd.edu/~ekalnay/pubs/2014-03-18-handy1-paper-draft-safa-motesharrei-rivas-kalnay.pdf
Dear Alex, NASA does not support the outcome of the project; anyhow it is fascinating issue
