摘要：The vast land and fertile soil in the Agusan River Basin lured people to use the land for agricultural andtree plantations. The agricultural plantation development in the floodplain may have some implications to the wetland ecology, particularlyon the water movement, biodiversity and in the overall relationships of the various aspects of the basin. Thus information on the agricultural plantation development and the use of agrochemicals that can contribute to water contamination in the basin were assessed as inputs for the management of Agusan River Basin toward sustainable development. Corn and rice are the dominant agricultural crops planted in the river basin. For the period 2005-2012, area for rice and corn production has been expanding. Likewise, the production area of oil palm (Elaeis guineensisJacq.) is increasing in the buffer zone of the basin. The contract growing scheme of large oil palm companies in Agusan del Sur is the major driver that encouraged landowners and cooperatives to venture in oil palm production resulting to the conversion of natural habitats in the buffer zones. Expansion of banana plantation and rubber has also reached the drier areas of the basin. The continued expansion of agricultural areas has changed the habitats in the basin. With the land use conversion, interconnectivity is reduced which is detrimental to the biodiversity. A policy review is, therefore, necessary to look at how to strike a balance between food production and biodiversity conservation.
