Unlike Java, Madura is troubled by low rainfall and poor soils. Because of the aridity, rice may be grown only once a year. For the same reason, Madurese emphasize livestock production; they raise sheep, goats, and especially cattle, some of the latter for export to Java. Further, population pressure results in small landholdings, and therefore many Madurese must work as traders and handicraft producers. Many also are fishermen, using outrigger canoes and large nets. Women work as traders and as laborers for wealthy farmers. Land is owned individually, but most villages also set aside communal land and land used to support village headmen.
