"Kadayawan sa Dabaw" is Davao City's premier festival and showcases the natural and cultural bounty of the land. A movable feast in August, the week-long merrymaking highlights the manifold tribal cultures of the region which are vividly expressed in traditional songs, dances, games and crafts. It is also on this occasion when a lively trade fair, capped by a flower-and-fruit float parade, takes place. Street dancing and popular entertainment complete the celebration. Agriculture-based industries thrive in the Davao region. A major exporter of bananas, citrus, mangosteen and other tropical fruits, it is also the biggest producer of cultured flowers in the country. Its surrounding waters are rich sources for commercial fishing. The world's largest city in terms of land area, Davao covers all of 244,000 hectares.
