Q & A

What is the Tonle Sap Lake known for in terms of biodiversity?

The Tonle Sap Lake is known for its remarkable Wetland habitat, being the largest and most important freshwater lake in Southeast Asia, covering over 12,000 square km. It supports a rich biological diversity, including over 400 species of fish, as well as reptiles, mammals, and birds.

Why was the Tonle Sap designated a biosphere Reserve by UNESCO?

The Tonle Sap was designated a biosphere Reserve by UNESCO in 1997 to ensure the long-term conservation of its vibrant ecosystem, which is crucial for the region's biodiversity and human livelihoods.

How has the fishing industry on the Tonle Sap Lake changed over time?

The fishing industry has seen a decline with fewer fish due to environmental changes and overexploitation. In the past, people could catch enough fish to support their families, but now the lake is poorer with fewer fish, indicating a need for conservation efforts.

What is the significance of the flooded forests in the Tonle Sap Lake ecosystem?

The flooded forests are critical habitats for fish production, providing spawning grounds and nourishment for the rich biodiversity. They are also essential for the livelihoods of the people living around the lake, as they support the fishery that many depend on.

What are the challenges faced by the communities living around the Tonle Sap Lake?

Communities face challenges such as overexploitation of fish stocks, degradation of the flooded forest for farmland and fuelwood, increasing pollution, and soil erosion. These issues threaten the health of the lake and the livelihoods of the people.

How does the hydrological cycle of the Tonle Sap Lake affect its productivity?

The unique hydrological cycle of seasonal flooding plays a significant role in the lake's productivity. During the dry season, water flows out, and in the rainy season, the Tonle Sap River reverses direction, causing the lake to swell and providing a rich environment for fish to spawn and flourish.

What is the role of the floating villages in the Tonle Sap Lake ecosystem?

Floating villages like Chong are communities that have adapted to the annual cycle of flooding. They rely on the lake's resources for their livelihoods, primarily through fishing. However, the growth of these villages also contributes to pollution and the pressure on the lake's resources.

What measures are being taken to protect the Tonle Sap Lake and its resources?

Measures include community involvement in resource management, promoting alternative livelihoods, increasing public awareness, making changes in laws and institutions, and establishing protected areas like sanctuaries and fish reserves.

How does the commercial fishing industry impact the Tonle Sap Lake's ecosystem?

Commercial fishing operations can be highly effective in exploiting the fishery, leading to overfishing and conflict with small-scale fishermen. They use large nets and exclusive fishing areas, which can deplete fish stocks and harm the lake's ecosystem.

What is the significance of the Water Festival in the context of the Tonle Sap Lake?

The Water Festival celebrates the reversing of the Tonle Sap River and the opening of the fishing season. It's an opportunity to educate the community about the importance of the flooded forest and sustainable fishing practices, ensuring the lake's resources for future generations.
