Graduate student Chong Seok Choi conducting research in Bogor, Indonesia on the opportunities to incorporate micro-scale renewable (solar) energy into existing cropping systems. The project goal is develop colocated crop-solar PV systems to maximize the efficiency of agricultural land along with providing several co-benefits (rural electrification, employment generation, energy for processing agricultural commodities locally)

Ravi, S. Solar-Agriculture colocation: Synergies and Tradeoffs, The 6th IPB talks on Complexity and Sustainability Sciences: Renewable Energy and Agriculture , Bogor, Indonesia, August 2017. (INVITED Speaker and panelist).

Graduate student Chong Seok Choi and undergraduate researcher Alex Cagle at the National Renewable Energy Laboratory’s solar energy test site near Golden, Colorado. They are conducting field experiments to investigate the environmental impacts (on soil properties and hydrological processes) of large solar energy infrastructures. (funded by DoE)

In summer 2017, Sujith Ravi was an invited visiting professor at the Intitute of Desert Control Science & Engineering, IMAU, Huhhot, Inner Mongolia.

Yu et al. in Ecohydrology (2017)  uses a novel process-based modelling framework to investigate the complex dynamics resulting from the introduction of exotic grasses under variable climate. Results indicate that  the system converges towards different steady states, depending on the magnitude of climatic variability.
