Agriculture, forestry, and fishing

remains the most important sector of the Cambodian economy in terms of its share of the gross domestic product (GDP), and it employs the vast majority of the workforce. Rice is Cambodia’s major crop, its principal food, and, in times of peace, its most important export commodity. Rice is grown on most of the country’s total cultivated land area. The principal rice regions surround the Mekong and the Tonle Sap, with particularly intensive cultivation in Bătdâmbâng, Kâmpóng Cham, Takêv, and Prey Vêng provinces.

Cambodia traditionally has produced only one rice crop per year because it has lacked the extensive irrigation system needed for double-cropping. Under traditional patterns of agriculture, planting normally begins in July or August, and the harvest period extends from November to January. Where there is little irrigation, the amount of rainfall determines the size and quality of the crop.

The government of Democratic Kampuchea made great efforts to build irrigation systems throughout the country. The results occasionally were notable, and in a few parts of the country farmers were able to grow two or, more rarely, three crops of rice per year. In some cases the irrigation works were poorly conceived and hastily built, and they soon collapsed. Most of those that survived were abandoned after 1979. Another significant problem is that millions of land mines remain in Cambodian fields from the years of warfare; this has severely restricted the amount of land available for cultivation.

In addition to rice, other food products include cassava, corn (maize), sugarcane, soybeans, and coconuts. The principal fruit crops, all of which are consumed locally, include bananas, oranges, and mangoes, and are supplemented by a variety of other tropical fruits, including breadfruits, mangosteens, and papayas.
Cattle, particularly water buffalo, are used principally as draft animals in the rice paddies and fields. Hog production has also played a large role in agriculture. Efforts to replenish the number of livestock—depleted by years of war—have been hampered by uncertain social conditions and the prevalence of animal diseases.

About three-fourths of Cambodia was forested in 1970, but by the early 21st century that portion had decreased to roughly half, with Cambodia carrying one of the highest deforestation rates in the world. The provinces bordering Thailand and Vietnam continue to be logged by large companies to whom the government has granted concessions, as well as by smaller entrepreneurs, many of whom do not obtain official permits. Illegal logging is a persistent and serious problem despite efforts to curb it.

Fisheries are important in the domestic economy. Fish in its various forms—fresh, dried, smoked, and salted—constitutes the most important source of protein in the Cambodian diet, and subsistence fishing is part of every farmer’s activity. The annual freshwater catch includes perch, carp, lungfish, and smelt. For larger-scale fishing, the government sells two-year leases to harvest segments of the Tonle Sap and inland rivers. Revenues from these sales have been significant at times, but the program has been fraught with corruption. Overfishing and environmental degradation around Tonle Sap have decreased the fish supply and driven up prices, and the sustainability of freshwater fisheries has become a matter of public concern.
