As a result of rapid urbanization in recent decades, the percentage of farmland in Hangzhou, China has shrunk at an alarming rate, with the food self-sufficiency rate dropping from 57% to 20% in just 20 years. Moreover, losing farmland means local farmers lose their original rural lifestyle and are forced to relocate to poorly constructed apartments provided by the government. Traditional farming practices are being lost, and future generations may opt for urban lifestyles and education, eventually leading to the disappearance of rural land traditions. This thesis proposes to establish junction areas in Hangzhou city’s main urban area to limit the speed and direction of urban sprawl. This will help preserve a large number of farmland areas to support the main city region in Hangzhou, meet a higher standard of self-sufficiency, and avoid the food security issues faced by first tier cities in China.
