Planning and development strategy for effective management of community forestry: lessons from the Thai experience

The forestry laws and regulations imposed by the Thai government to solve chronic deforestation have created conflicts between rural communities and government agencies over the use and control of forest resources. Therefore, the research carried out for this article focused on the study of community-based forest management practices in the northern region of Thailand to determine whether community-based forest management can lead to sustainable use and reverse the deteriorating situation and related problem of deforestation.
This study was conducted in a district of Phayao Province in northern Thailand, where a natural watershed has recently been managed jointly among ethnically diverse local communities living in upstream and downstream areas under the promulgation of the National Park Act. Research was based on both secondary and primary sources of data and information. An intensive field survey was also conducted through a standard questionnaire, supplemented by group discussions and informal interviews to understand the historical development of settlements in the study area.
The joint management of the community forest by the community, government and non-governmental organisations (NGOs) was recommended under the decentralised and participatory planning framework in the study area and also in other areas with similar environmental conditions. Equally important in promoting community forest management were the facilitating role of forest officials, the provision of support services, monitoring and enforcement of control mechanisms, and capacity building of local organisations.     

Excessive fluoride consumption increases haematological alteration in subjects with iron deficiency,thalassaemia, and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency

Excessive fluoride consumption leads to accelerated red blood cell death and anaemia. Whether that increases the haematological alteration in subjects with haematological disorders (iron deficiency, thalassaemia, and G-6-PD deficiency) is still unclear. The fluoride in serum and urine and haematological parameters of students at Mae Tuen School (fluoride endemic area) were analysed and compared to those of students at Baan Yang Poa and Baan Mai Schools (control areas). Iron deficiency, thalassaemia, and G-6-PD deficiency were also diagnosed in these students. The students at Mae Tuen School had significantly (P < 0.001) higher levels of mean fluoride in the serum and urine than those in control areas. In both control and fluoride endemic areas, students with haematological disorders had significantly lower levels of Hb, Hct, MCV, MCH, and MCHC than those without haematological disorders. Moreover, the lowest levels of Hb, MCH, and MCHC were observed in the students with haematological disorders who live in the fluoride endemic area. Thus, the excessive fluoride consumption increased haematological alteration in subjects with iron deficiency, thalassaemia, and G-6-PD deficiency and that may increase the risk of anaemia in these subjects.
