From the About Us: "DIVA-GIS is developed by Robert Hijmans. Previous versions were co-developed with Edwin Rojas, Mariana Cruz, Rachel O'Brien, and Israel Barrantes. The development has benefited greatly from intellectual and practical contributions by Luigi Guarino and Andy Jarvis. Our objective is to develop a free, and simple but versatile GIS program, that is particularly useful for studying the distribution of biodiversity. Development of earlier versions of DIVA-GIS was supported by several CGIAR institutes: Bioversity International, the International Potato Center, the International Rice Research Institute, and by the University of California, Berkeley, Museum of Vertebrate Zoology and others."
