Currently, Lord Mayor Boris Palmer (Green Party) has set the ambitious goal of increasing the population of Tübingen to 100,000 within the next several years. To achieve this, the city is closing gaps between buildings within the city proper by allowing new houses to be built there; this is also to counter the tendency of urban sprawl and land consumption that has been endangering the preservation of rural landscapes of Southern Germany.
