Main fields of research and expertise

Research engineer at the IRD, attached to the Institute of Ecology and Environmental Sciences of Paris (IEES-Paris), Jean-Louis Janeau worked for MSEC program during 15 years. The last period was in Thailand from April 2016 to August 2019 in the Land Development Department (LDD), as expert-hydro-ecologist for the TICA program Towards an improvement of soil and water quality in the context of land use and climate changes in Thailand. Previously, he coordinated the activities of the MSEC regional project (Multiple Scales Environmental Changes), in which he has already been involved in previous positions (2000-2006) within the International Institute for Water Management, IWMI-IRD in Thailand and Vietnam (2010-2015 as head of the MSEC Vietnam).

During his 38-year career, he has worked in various research programs in West and South Africa, Mexico, and Ecuador. His areas of expertise are hydrophysical measurements and erosion parameters in natural and agricultural environments, and mapping of soil surface features. He also worked as a consulting engineer in hydroecology for natural disasters (El Nino and 1998 landslides) in Ecuador, with the Ecuadorian government and for the establishment and management of hydro-sedimentary balances of ecosystems. natural and anthropised within the municipality of Quito for 4 years. He also transmits his experience by intervening in a Master’s degree from the University of Tours.

JL Janeau is strongly involved to IRD since years as member of scientific committees and scientific council and since 2013 member of the steering committee. Moreover, he was acting representative of IWMI in Thailand and he is was acting representative for IRD in Thailand.

Since September 2019, he is posted at IEES-Paris, Sorbonne university, France.
