Meanwhile, data from both provinces showed that all jobs in the households are informal. Workers in formal employment receive significantly better wages than those in informal employment and male workers are better off than their female counterparts who are more likely to involve in informal jobs. As more workers leave this sector to find better-paying careers in industry and services, moves can be made to intensify agricultural production, with rising demand for engineers, engineering geologists, planners and managers specialising in these fields. Addressing these changes will require the development of a range of higher level skills associated with leadership, technical expertise, problem solving, management and sustainability. An increase in traffic might also call for more skilled merchant mariners and port co-ordinators.
