In order to reveal the relationship between the geo-environment, especially drinking water, and the disease, the senior author has made an investigation on the pathogeny and epidemiology of the disease and some characteristics of drinking water, including the source, chemical composition and radioactivity of all kinds of drinking water (river water, spring water, running water). We adopted a routine method to analyze major ions and the atom spectra of the minor elements. At the same time, we made similar investigations in Muyu Town for comparison. The results showed that all the indices of surface water & ground water in the two towns have not gone beyond 《Water Quality Standards for Drinking Water Source》 (CJ3020-93) and that the radioactivity (γ-ray) of the water from Songbai Town is higher than that of the water from Muyu Town, but the incidence of the disease is higher than that in Muyu Town. So, it can be concluded that there is no direct relationship between the disease and the hydro-environment.展开更多

Data were collected through questionnaire surveys, in-depth key informant interviews, physical field visits and documentary reviews. A total of 44 subjects were involved in the study. SPSS, Microsoft Excel and content analysis were used in data analysis. Findings indicated that inadequate capacity building, passive community participation and involvement in VLFRs management fostered the continued forest degradation and deforestation in the study area. It was further observed that on average 2.04 ha of forest was being lost every year through anthropogenic activities, mainly farm expansion, charcoal business and firewood. In order to achieve VLFRs sustainability, the study recommends improvement of relationship and coordination among VLFRs key stakeholders, participatory preparation of forest management plans, enforcement of community forest management bylaws, and use of energy saving stoves to reduce overdependence on forests as source of energy.展开更多
