From 1972 to 1980 he worked as agroclimatologist at the Central Research Institute for Food Crops (CRIFCI) in Bogor, Indonesia, in the framework of a bilateral agricultural assistance programme between Indonesia and the Netherlands. His research activities focused on the relationship between climate and rice-based-cropping systems.

From 1980 to 1982 Roel worked as guest researcher at International Institute for Land Reclamation and Improvement (ILRI), Wageningen, the Netherlands.

Roel was a visiting scientist at the International Rice Research Institute (IRRI), Los Banos, Philippines from 1982 to 1985, where he was a Project Manager of a joint IRRI-WMO Rice-Weather Studies program.

Since the mid 1980s until his retirement in 2002 he worked at ISRIC, Wageningen, The Netherlands. First as senior scientist and as part of his duties he worked for 12 months on the agroecological characterization of Madagascar in the framework of a Rice Research and Training Project of the International Rice Research Institute (IRRI). From 1987 to 1990 Roel was the Project manager of a joint UNEP-ISRIC project: World Map on the Status of Human-Induced Soil Degradation (GLASOD, published in 1990). That map has been widely used and was his masterpiece.
