The preservation of biodiversity is a high priority among biologists, ecologists and environmentalists. The impact that human activities have on biodiversity is clear; however, few studies have focused on the importance of biodiversity to natural and agricultural ecosystems. In fact, many natural species are essential to sustainable agricultural programs. A new school of thought is appreciating the ecological principles and benefits that diversity of natural biota have for humans and the environment. Landscape ecology and agroecology can play a major role in protecting the environment and conserving biological diversity. The practical opportunities for improving the sustainability of agriculture and making it more environmentally sound were discussed at the Symposium on Agroecology and Conservation Issues, from which 22 papers were collected for this volume. Strategies for increasing biodiversity in agricultural landscapes are provided alongside discussion that agriculture will continue to spread into forests, to meet the growing need for food. Although humans recognize the value of crop and livestock species, few really appreciate the fact that agriculture and forestry cannot function in a productive sustainable way when significant numbers of species in natural biota are lost.
