Abstract | This study of land use change and its implications on local livelihoods was conducted in Tam Dinh commune located in the Ca River Basin, the central of Vietnam. Land use classification for three years 1989, 1998 and 2005 was done using landsat TM, and ETM+ images in integration with GIS tools. Factors of land use changes were identified and examined by applying linear regression model at p<0.05 which showed the relationship between each land use type and its influenced factors, the correlation among factors affects on the land use types. Local livelihoods assessment was analyzed employing Sustainable Livelihood Assessment framework combined with weighting index method to assess the level of accessibility to the assets of local people and their livelihood strategies. Household survey was carried out with 68 households in two villages focused on the spatial location of each village compared to road systems. The results showed that land use mapping achieved high accuracy as 94.7% of land use map 2005, and 88.5% and 88.42% were achieved for 1989 and 1998, respectively. There was a big change in swidden agriculture in both periods with 72.3% of rice swidden being degraded forest (767.5 ha) and 10.9% of that being secondary forest in period 1989-1998 and there were 44.1 % rice swidden area converted to degraded forest and 27.0% of it was converted to secondary forest in the period of 1998-2005. Forest land changes give a good signal of reforestation with the transition of degraded forest to secondary forest and secondary forest being natural forest. The transition of degraded forest to secondary forest experienced huge amount of forest area 1,406 ha (28.8%) and 1,852 ha (37%) in the periods of 1989-1998 and 1998-2005, respectively. The area of secondary forest generated to natural forest was 508 hectares in the period of 1989-1998 but it got highest growth rate in the period of 1998-2005 with a huge area of 1,357 hectares equivalent 32.2 % of total natural forest area. Factors of land use change, especially agricultural land use, has been addressed as the number of household members, education and land holding size played the highest roles. Local livelihood components were presented by labor forces, rate of educated household member, agricultural occupation, forest land holding size, income from livestock. Since the area of irrigated paddy was not increased due to limitation of suitable land, livelihood of people in Tam Dinh being more depended on the swidden cultivation, collection of firewood. Recently, household member has to earn their job from big cities, or urban area for labor wage. Furthermore, land use change need to model for future planning with the more involvement of socio-economic data. |
