Cover image: Pictured are rice farmers in the village of Wongaya Gede in Bali, Indonesia, where the landscape is a rich mosaic of rice terraces and agroforestry crops and has been listed as a UNESCO World Heritage cultural site. These farmers adapt constantly, combining traditional irrigation and agronomic techniques with innovative use of genetic material and locally adapted mechanization. Jeffrey Sayer and Kenneth G. Cassman suggest that agricultural innovations such as those used in Bali are essential to address concerns about the environmental impact of agriculture while producing enough food to support the world’s population. See the Introduction to the Agricultural Innovation to Protect the Environment Special Feature by Sayer and Cassman on pages 8345–8348. Image courtesy of Agni Klintuni Boedhihartono.
