Sustainable tourism means taking responsibility for your own actions and the impact they might have on the environment as you travel. It means paying attention to the environments you find yourself in and respecting the communities you visit. The International Ecotourism Society (TIES) defines eco-tourism as responsible travel to natural areas that conserves the environment and improves the well-being of local people. One thing you will notice in Cambodia is that respect for locales is low. Rubbish and plastic bags are simply thrown out onto the street. Heavily polluting vehicles often create a thick haze over towns and cities. You don't have to join in. Dispose of your own waste, don't use detergents or shampoo in lakes and rivers, and don't use electricity wastefully.

The environment in Cambodia has taken a real beating over the years. It is considered one of the most vulnerable countries in Asia by environmental activists and experts. High-canopy rainforest that once covered much of the country has been decimated by legal and illegal logging. To give you an idea of the scale of this, in 1970 Cambodia was 70% primary rainforest. By 2007, it was 3.1% primary rainforest. The soil erosion resulting from the mass deforestation is also a long-term problem. What hasn't been achieved by active plunder has been achieved by population growth in a country where subsistence-level living is the norm and resources are not used in a sustainable or renewable way.

A lot of the wildlife has also been poached or trafficked. Three-fourths of Cambodia's wildlife areas have disappeared as a result of the ravages of logging. Endangered species in Cambodia include three species of gibbon, several species of wild dog and wildcat, leopard, tiger, Asian elephant, Sumatran rhinoceros, Thailand brow-antlered deer, kouprey, giant catfish, Indian python, Siamese crocodile, and estuarine crocodile. As of 2001, 23 of Cambodia's mammal species and 18 of its bird species were endangered. Cambodia has a problem with the illegal hunting of rare species, something to keep in mind when shopping in the markets.

There has been some progress in environmental tourism and attempting to preserve what is left. In Kratie, for instance, fisherman no longer use grenades to fish, thereby killing the endangered river dolphins. Yet there is also a lot to be worried about, including the rapid development of Cambodia's coastline and nearby islands, particularly around Sihanoukville. There is a great deal being built there, and the developers are almost entirely unregulated.

"Heritage Friendly" Establishments -- Much of Cambodia's ancient history has been lost, thanks to its violent past and the continued looting and trafficking of Khmer artifacts. To help prevent this, look for the "Heritage Friendly" logo. This logo was created by the Heritage Foundation (, an organization working to preserve Khmer antiquities and culture. The presence of the logo indicates that a business or organization has met certain standards that help protect Cambodian heritage. Travel to Cambodia is good, but responsible travel is even better.

Eco-Tourism in Cambodia

With the construction of the brand-new road from the Thai border at Koh Kong-Hat Lek (near Trat), the Cardamom Mountains, one of the last areas of forest wilderness in mainland Southeast Asia, is set to become the scene for eco-tours, with Koh Kong as its base. This is something that will have to be managed very carefully, if it is to do more good than harm. Hoteliers have also begun to adapt to the ecofriendly trend, opening ecoretreats and a few carbon-neutral options.

In Ratanakiri and Mondulkiri, there are more and more opportunities to enjoy one of Cambodia's most remote areas. The heavy jungle is home to 12 different Khmer Loeu ethnic minority groups. On the way, you can stop in Kratie and go dolphin spotting on the Mekong. The rare freshwater Irrawaddy dolphins break the surface every now and then, but they remain powerfully shy.
