#Ongoing Projects

Nutrilift (2021-2026) : Role of perennial vegetation as a « nutrient lift » within the critical zone ; ANR AAPG ; PI : Jean RIOTTE

The objective of this project is to quantify the nutrient uplift and redistribution in a forest ecosystem (Mule Hole) and in two agrosystems (Berambadi), including agroforestry and irrigated agriculture, all located in the Kabini CZO/ SNO M-TROPICS. These systems represent a decreasing gradient of interactions between the lower and upper parts of the Critical Zone. For this, we aim at developing a new methodology involving several scientific disciplines, combining direct measurements of nutrient availability by depth, roots characterization and dynamics, detailed quantification of nutrient uptake that will be used in an integrated hydro-eco-geochemical mode.

HiDRATE (2023-2027) : integrating High resolution Data from Remote sensing And land surface model for Transpiration and Evaporation mapping ; ANR/FNR ; PI : Gilles BOULET

The HiDRATE project aims to estimate the space/time subcomponents of evapotranspiration and therefore gain a better knowledge of the respective roles of the ecophysiological constraints on the vegetation functioning and the surface soil moisture extraction through evaporation.

TransIndianDairy (2021-2024) : agroecological TRANSition of INDIAN DAIRY systems : a focus on institutional change ; ANR JCJC ; PI : Marie DERVILLE

The project TransIndianDairy aims at understanding the role of technical, organisational, and institutional innovations in driving agroecological transition of Indian dairy systems. We hypothesise that institutional innovations are central for triggering evolutions of stakeholders’ thinking and acting (institutional change), which will enable an evolution of the management of productive resources and / or of their configuration (structural change).

(2018-2024) : Multiple Isotope Fingerprints to Identify Sources and Transport of pesticides in the tropics ; AIEA CRT ; PI : M. SEKHAR, L. RUIZ

SMARA (2022-2023) ; CNES

The objective of the SMARA project is to evaluate the potential of the very high spatial and temporal resolution of VENμS to characterize surface landscape properties related to agriculture and water resources in semi-arid and tropical agrosystems: agricultural practices, land use, surface water storage and soil surface moisture and water stress.The project is dedicated to two contrasting and complementary contexts characterized by high spatio-temporal variability of surface landscape properties: the Berambadi watershed in Karnataka (India) and the Merguellil floodplain near Kairouan and Lebna in Tunisia.

TRISHNA (2021-2023) : Thermal infRared Imaging Satellite for High-resolution Natural Resource Assessment ; CNES-TOSCA ; PI : Jean-Louis ROUJEAN

The Indian and French Space Agencies, ISRO and CNES, have conceptualized a space-borne Thermal Infrared Reflectance (TIR) mission, TRISHNA. Its main objective is to monitor the evapo-transpiration and the water stress of the vegetation. Assessing evapotranspiration and furthermore Gross and Net Primary Productivity (GPP and NPP) will in turn assist in quantifying water use in rainfed and irrigated agriculture, water stress and water use efficiency, with expected applications to agricultural drought and early warning, crop yield prediction, water allocation, implementation of water rights, crop insurance business and agro-advisories to farmers.
