About Kritee

Kritee K

Senior Scientist


Areas of expertise:

Climate smart agriculture, Soil carbon, Soil Health, Rice, Methane and nitrous oxide emissions, Nitrogen & Water use efficiency, Environmental microbiology, Stable isotope biogeochemistry, and Mercury pollution


Kritee has close to twenty years of cross-disciplinary research experience. At EDF, she is a part of EDF’s climate team that is helping accelerate rural poverty alleviation, strengthen adaptation to the effects of climate change and promote climate mitigation in Asia. Her work is laying the groundwork for landscape level agricultural carbon offset protocols for small land holdings. Between 2011-2016, she directed a multi-partner research team working on “Climate smart agriculture” at six labs across five states in rural India and examined the effectiveness of different farming practices for rice and other regional crops in increasing yields, improving farm economics and soil quality as well as decreasing greenhouse gas emissions.

Kritee is also helping lay the groundwork for jurisdictional level government action on land use change in India such that triple win (i.e., food security, economic prosperity, and climate adaptation and mitigation) can be achieved. She supports EDF’s engagement with Fair Climate Network (FCN), a network of NGOs in India that have worked together to test scalable climate smart rural development approaches such as deploying clean cooking systems and climate smart agriculture.

She also provides scientific input to EDF’s domestic legal teams’ efforts to improve government policies related to the energy sector, with a focus on mercury pollution from electric generation units.


Kritee gained postdoctoral experience on nitrogen cycling in the environment as a Camille and Henry Dreyfus post-doctoral fellow in Environmental Chemistry at Princeton University. Kritee also served as a Governor’s Executive Fellow at Eagleton Institute of Politics.
