Inle lake in Shan State, one of the country's biggest tourist draw,is a national treasure and
a major attractive destination. The lake is also home to about 25,000 people- many from the
native Intha group-who have lived along its shore for centuries.
Now their homeland is danger. Sewage and agricultural chemicals are poisoning the water. Sediment
is making the lake more shallow, breeding weeds and algae while killing fish. Population growth
and tourism add to the strain, while new fish species threaten the fragile ecosystem.
The polluted water has become unliveable for some native fish. They also suffer from competition
with exotic fishes which have spilled into the lake from nearby fish farms during floods.
According to environmentalists's saying, the biggest pollutants are pesticides and fertilizers
from the floating tomato gardens scattered across the surface of the lake; the chemicals easily
seek to the water.
The population on the lake has jumped 20 per cent since 1983, according to Immigration and
National Registration Department statistics. Increased boat traffic, household waste,
agriculture and cottage industries have "compounded the acceleration of environmental
degradation", according to the report by the department.
Not long ago, the lake was the sole source of drinking water for Inle's residents. As pollution
rises they depend more on tube wells and bottled water. But many are stay left without a safe supply.
The sewage is a major source of pollution, and as the population grows, the risk of water-borne
disease is a major concern.
A bigger threat to long term sustainbility is the build- up of sediment on the bottom. This has
made the shallower and changed the balance of minerals in the water- letting plants and algae
thrive but hurting native fish.
The sediment has been increasing, mainly due to slash-and-burn agriculture on the hills around
Inle, which accelerates erosion into the lake. The build-up of sand and stones in the lake has
destroyed some farms.
The sediment is starting to build up in the middle of the lake, overriding Inle's ability to
clean itself.Nine artificial lakes built a century ago to catch sediment are mostly full.
Until about eight years ago, the lake bed was mostly clear of plants. Now weeds have choked the
bottom and are shooting up to the surface. Too many plants reduce the amount of oxygen in thewater, making it difficult for fish and other organisms to survive. The department of irrigration
has been trying to clear out the weeds on the main waterways, but it is an uphill battle. The
weeds have now spread across the entire lake.
"Our mother (Inle) has given us many resources so that we live well..... Now she is old and
wearing out",said a concerned Intha who is active in the conservation movement.
"It is a delicate time to realise that our turn has come to take good care of her".
