Community participation on Namsam upstream forest management a case study at: Khangthi, Houaxieng and Tham village, Samneau District, Houaphan Province

Abstract: This paper studied community participation in management of Namsam upstream forests is case study of Khangthi, Huaxieng and Tham village, Samnuea district, Houaphan province. The study aimed on the approaches to water quality management and exploredthe social and economic conditions affecting the forest and analyzed the condition of the village in the forest protection contribution. The research collected information from interviews, participatory observations to inspire people to understand the importance of water management. The research focused to three villages, including 318 households and interviewed 100% of each village. The community participation on upstream forest management activities has illustrated that there are 8 main activities such as forest monitoring, wild life management, aquatic animals forbidden management area, making the regulations on upstream forest management, dissemination campaign, forest restoration and maintenance and raising awareness. Socio-economics was investigated in three villages for estimating average of income and expenditure. The average income per household per year at Khangthi is 2,416 US$, Houaxieng is 1.989 US$ and Tham village is 1,672 US$. The expenditure per household per year at Khangthi is 726 US$, Houaxieng is 675 US$ and Tham village is 625 US$. Participation of each household level to be percent, the rich household for 52.78%, medium 85.80% and poor household at 84.46%, and there are 8 factors attracting community participation on upstream forest management. The species diversity at Khangthi village is 60 species, 41 families and 382 trees. Houaxieng is 75 species, 44 families and 415 trees and Tham village is 93 species, 51 families and 378 trees. The average height was 16.45 m, the average DBH per plot was 19.57 cm, the average volume per plot was 21,116 cubic meters, average of volume per hectare was 351.940 cubic meters and finally the average density was is 678 trees per hectare. The value of concentration at Khangthi village such as Dissolved Oxygen (DO), Electrical Conductivity (EC), Potential of Hydrogen (pH) and Chemical Oxygen Demand (COD) were higher than Houaxieng village and the water flow was the lowest. There was no over standard value of water quality. Houaxieng village has shown that water flow, DO, EC, pH, COD and TDS were lower than Tham village, and special DO value was lower than standard which would affect human health and aquatic life. The result of soil analysis from each plot were shown as follows: pH value in Khangthi village from lowest to the highest was 5.62 -6.61; P: 0.048-1.321g/kg, N: 0.677-3.883g/kg and K: 2.659- 4.412g/kg. The pH value in Houaxieng village from the lowest to highest was 5.44-5.76; P: 0.178-2.127g/kg; N: 0.533-4,083g/kg and K: 2.471-7.357g/kg. The pH value at Tham village from the lowest to the highest was 5.13 - 5.67; P: 0.038-1.877g/kg, N: 0.637-2.073g/kg and K: 1.735-5.865,g/kg
