Sustainable agriculture has emerged as a key issue in agricultural development andnatural resource management because of widespread and growing concern about the seriousness ofdegradation of the world's natural resource base and ever-increasing pressures on these resources fromcontinuing rapid population growth. This paper examines the changes in land use and the problem oftropical deforestation affecting the world's land resource base for sustainable agricultural development.Global land-use changes have been slow in the last decade. However, changes in land-use patterns havebeen significant in many developing countries, especially the conversion of forest land into agriculturalland to meet increasing demand for food and fibre. It is estimated that over 11 million ha of tropicalforests are cleared every year in Latin America, Asia, Africa, and the Pacific Islands. The most seriousconsequence of tropical deforestation is soil erosion, which may greatly increase after forests are cleared.It is also apparent that tropical deforestation is contributing to global climate change. Improvedagricultural sustainability, combined with policies to protect natural resources, is urgently needed tosupport the rapidly increasing population in developing countries.
