Thailand is one of the world's leading exporters of agricultural produce--fiber and food crops. With the exception of rice, an important part of these export crops are produced in the Northeast and has resulted in widespread deforestation. Much of the cleared land has been planted to cassava and kenaf--both stemy crops that provide little protection to the soil. Clearly, soil erosion losses in the Kingdom as a whole and the Northeast in particular, are so severe that action must be taken to protect the valuable resource base. The project envisioned in this proposal is designed to make a major impact on changing farming practices and installing appropriate soil conservation practices that will measurably reduce soil losses in targeted project areas.
