4.3.2.2.The Socio-economic Conditions in the Subproject Area a) Socio-economic Condition from Field Survey: Demographics - The average household size in the samples surveyed is 4.8, which is higher than the national average of 3.89 (Statical yearbook, 2013). Household size for household is smaller on average than men-headed households (4.85 people compared with 4.91 people, respectively) which is expected as most of them are single parent households. Table 4.9: Average member and labor in a household Household Size (Group Average) Members in a household (%) 1-2 people 3-4 people 5-8 people 9 people and more Total 4.8 17.5 36.2 35.3 11.0 Commune/ward Ngoc Son commune 4.8 17.5 36.2 35.3 11.0 Group of gender + Headed men household 4.91 17.5 34.6 36.7 13 + Headed women household 4.85 21.9 31.9 31.2 15.0 Group of income Group 1 (poorest) 17.0 26.9 36.2 19.9 Group 2 15.5 32.1 34.6 17.8 Group 15.3 3.5 37.5 13.7 4 8.7 49.7 34.7 6.9 Group 5 (richest) 13.5 49.3 35.2 2.0 Source: Survey data The data showed that in the sub-project area large household size is relatively in higher proportion than in other areas of Vietnam. In general, large household size means more labor for the family in the rural areas thus contributing to the relatively lower poverty rate in the area. Occupation - The agriculture, forestry and fishery sector provides the main source of employment for the inhabitants in the sub-project area, accounting for 41.6% of the working age population. Still significant percentages are reported to be working in the trading services (14.3%) and handicrafts (15.6%). Table 4.10: Main occupation of laborers (included all household laborers)
In the land and stone mines, contractors should follow the environmental protection issues, including: - Machines and construction equipment need regular maintenance, in accordance with quality requirement during operation. - The hazardous such as oil and other chemicals must be strictly managed, stored in separate areas around the constructive area, waiting the treatment from competent authorities. Workers need to be equipped with protective tools while working in the made ground. - Mining area must have fences, the entrance gates must have protective latches in order to prevent the entry of people and animals; - During dry days, the land mine should be sprayed with water. - The contractor must select the material provider that has the suitable business license. - These mitigation measures are simple, easy to implement, and do not need the complex technology and technique. - However, the contractor must prepare the constructive machines, warehouse, and yard before starting construction. - It should be coordinated between the specialized units to ensure that the waste is being handled. - These measures will bring good results if the construction contractors and workers are aware and educate about environmental protection, and they are tested by the project owner and other stakeholders. 7.2.1.3.
