Following the water surey along the Everest highwey I had taken befor, this time I took the survey in Annapuruna Sanctuary. I have tried to see the difference in pollution in these areas. Stretching around the Dodhkoshi tributary river basin as far as high above, grazing gounds for yak. are developed, and this causes relatively high pollution. But in the Modi Khola tributary river basin, gazing grounds (for water buffalos and cattl) are not located at so high an altitude, and thus water pollution is lessserious. It is likely that the differences in poliution among tributaries depend on thevariety ofdomestic animals kept there. Compared with the Dodhkoshi area there are more farm houses inthe Modi Khola area where the NH4+ emmision is also by and large higher. Concerning waste disposal systems, several rubbish dumps are to be found, but garbage is not properly treated. This is because anti-government activities are rampant in Annapuruna and public order is unstable. Political stability is essential for environment conservation. |
