Serie 2-7; This series was shot on October 28-31, 2019, in Jambi province (Sumatra), during visits I conducted, together with CIRAD researchers Jean Ollivier and Alexis Thoumazeau and partners from rural development NGOs and Jambi University professors, of several places and projects related to agronomic practices in the local oil palm production sector. I also visited, with the invitation of professor Aiyen Tjoa (universities of Jambi and Palu), the EFForTS research project of universities of Jambi and Gottingen, on the effects of landscape transformation associated with the development of rubber and oil palm plantations. The subjects include the warehouse of a local input supplier, a plant nursury, an oil palm mill, the plantation of an independent smallholder (in the area, many of the recent plantations are installed not by firms, but by independent farmers), the delivery of fresh fruits by smallholders to an intermediate collector with his truck, a meteorological station installed for the EFForTS project, plantation workers transported in a truck. I coordinate the research project EXPALMIND on the effects of plantation agriculture on land use and food security, funded by the Mutalim CNRS-INRAE fund in 2019-2021, and this project involved geographers from CNRS-LETG and CIRAD-Systèmes de pérennes, and my participation was part of that project.
